The article describes a method for flashing Samsung phones running Android via a computer using the Odin program.

Phones are flashed not only after long use, but sometimes immediately after purchase. If we talk about, like or something like that, then often the system cannot do without viruses, advertising and other things. Therefore, we are looking to make working with the phone comfortable and convenient.

We will divide this article into 2 parts. The first part will be dedicated to Samsung devices, and the second part to other brands. We will also look at ways to flash a phone and what programs are needed for this.

Firmware methods

An Android device can be flashed in two ways:

You may like:

1. Using a computer
2. Through recovery

Firmware via a computer is carried out using special programs, and through recovery the device is flashed almost without the participation of a computer, but more on that later.

Types of firmware

There are two types of firmware: official and custom. Official firmware is developed by the manufacturer itself, while custom firmware is made by ordinary people sitting at home. There is also such a thing as stock firmware. Stock firmware is the firmware that was installed by the manufacturer on the smartphone. Naturally it is official.

Programs for Samsung firmware

For Samsung phones and tablets there is a special flashing program called . It is intended only for gadgets from Samsung, so there is no point in even trying to flash a device from another brand using Odin.

This program is downloaded and installed on the computer, its main window looks like this:

Firmware instructions

First, install the Odin program on your computer. Next, download the archive with the firmware and unzip it to a convenient place on your computer. We open the folder and see five files there, of which we need four. Now let's launch Odin.

In the program we see four items: Bootloader, PDA, PHONE, CSC. Each item needs to upload its own file. There are 4 files in the firmware, the first two letters of which tell you where to download the file. Here is the scheme according to which you need to upload files:

AP file – PDA tab, BL – Bootloader tab, MODEM – Phone tab, CSC – CSC tab. If you are using Odin version 3.10, then the first letters of the firmware files in it match the names of the items in the program.

But there are firmwares with only one file in the archive. If your smartphone has exactly this firmware, then this file needs to be uploaded to the PDA. Don't touch the rest of the items.

Now let's prepare the phone. First you need to turn it off. Now you need to simultaneously hold down the power button, volume down and the Home button. Different inscriptions will appear, press the volume up button. You will be taken to a special menu.

We connect the smartphone to the computer using a USB cable. After connecting, under the inscription “ID:COM” the port number on the computer to which you connected the smartphone should be displayed. If the inscription appears, another inscription “Added!” should appear in the lower left corner, and then press the “Start” button. The firmware process will begin, which will take from 5 to 15 minutes.

Upon completion of the firmware, the inscription PASS will appear in the upper left corner. The caption box at the end should say “All threads completed. (succeed 1 / failed 0)". This means that the process is completed, 1 is installed, 0 errors. This means everything is installed. You can turn on your smartphone.

The first startup will take longer than usual, so don't worry.

After the firmware, it is advisable to make wipes. This is a reset of all settings. To do this you need to go to . To go there you need:

• Turn off your smartphone.
• Press and hold the Home button, the power button and the volume up at the same time.
• Select the Wipe Data item by scrolling to it with the volume rocker and pressing the power button to select.
• Select “Yes”
• Select Wipe Cache
• Select “Yes”

At the request of some readers, I finally decided to write an instructional article on firmware for SAMSUNG I9000 Galaxy S (hereinafter simply SGS). Causes:

1. Yesterday's flagship still looks quite an attractive purchase today, especially against the backdrop of the ever-decreasing cost of the gadget. Powerful hardware, excellent screen, good build, attractive appearance (I agree in advance that it’s not for everybody, but I’m satisfied with all the other advantages, so I’ll ask in advance without discussing the appearance in the comments, that’s not what the article is about). As we see, SAMSUNG also does not discount this device, has released several modifications of it and continues to develop the SGS line.
2. The manufacturer, as always, is in no hurry with official firmware updates through the standard KIES channel, however, on thematic sites you can always find the latest versions of factory firmware, received there from insiders. In addition, delays in official updates are due to regional aspects. In fact, no one can forbid you to use any new firmware for another region; Russian and Ukrainian languages, from experience, are present everywhere, you will not notice the difference with the “localized” version.
3. I can say that the SGS is one of the most interesting phones for geeks, because... has a very powerful community on the xda-developers website and on other sites on the Internet, which is constantly developing improvements, fixes, software, hacks, visual themes and, of course, the firmware itself (hereinafter referred to as ROM) for this device. At the moment, you can count about a hundred firmware versions of Android 2.1-2.3 for every taste. More details about developments for SGS on the xda forum here: http://forum.xda-developers.com/forumdisplay.php?f=656 and on the Internet. The topic of custom software is especially relevant against the backdrop of problems with factory firmware (memory management, slow file system, music playback artifacts, etc.). In addition to fixing factory errors, custom ROMs often offer additional functionality and a host of improvements.

In principle, instructions for SGS firmware are found quite often on the Internet, but mostly they are all in English, which creates certain difficulties for users from the former CIS. I hope that this instruction will really help those who do not know English well.

In this article we will look at the main fundamental points that you need to understand when you are flashing a phone. I will not be tied to any specific ROM, because... they all have a different installation sequence, usually described in the xda forum topic header, where you will also find links to the necessary files. If you understand the theory, you can flash any firmware and install any update.

Preparing the phone for firmware.

The first thing you need to check is whether your phone has a three-button boot mode. If you are just getting ready to buy, it is best to do this right in the store. With the device turned off, press the volume down, home (center button) and power buttons in sequence. Hold until the phone turns on. You should see something like this:

If you see it, then everything is OK, if not, it means the boot mode is blocked at the factory (this also happens). If you already own an SGS and it doesn’t work, don’t despair, the three-button mode can somehow be unlocked, how to do this - look at the xda forum in the corresponding topic (I didn’t go into too much detail - I was lucky and everything works for me). If you have not yet made a purchase, it is better to look for another copy. In the absence of a three-button mode, you will only be able to receive updates through KIES, which is absolutely unacceptable for a geek! To exit download mode, just remove the battery, nothing bad will happen.

Download the ODIN Multidownloader software on your Windows computer. This program has many versions, I use Odin 1.3 and it has never let me down. The program consists of one file, starts from a folder and does not require installation on a PC. This is what it looks like when launched:

Since the program is intended for use in service centers, you can flash up to 8 phones at a time. You see at the top eight slots with indicators for connecting phones to virtual COM ports (that’s why multidownloader). You most likely will not need this, so the main thing is the first slot, which will display all the stages of connecting and downloading the firmware to the phone, then keep an eye on it as you work.

Have you looked at the program? Now close it! The next step is to connect your PC to your phone in download mode. Usually, to do this in Windows 7, you just need to connect the SGS with the download mode enabled to the PC. Important note: Use the USB port on the motherboard for this connection. Perhaps everything will work through the front panel and all sorts of splitters/hubs, but I don’t recommend it. From experience there can be problems. Make your first connection without running ODIN. The system will see the hardware and install drivers. If something goes wrong (especially on XP), install the KIES package and the device drivers will be loaded onto the computer. After installing the drivers, check if the ODIN program sees your phone. TURN OFF KIES!!! Launch ODIN, enter SGS into boot state, connect to PC. If the connection is successful, you will see a yellow indicator in the first slot. Congratulations, everything is ready to upload the software to your SGS!

Phone firmware. ODIN program options.

What can you do with the ODIN bootloader? You can upload any ROM, factory or custom, with or without a complete repartition of the file system, root the phone, flash a new kernel into the existing firmware. Often, the firmware update procedure via ODIN is included as one of the stages of a more complex phone software update. Attention here! Further, when working with ODIN, always adhere to the following sequence:

1. Turn off KIES if it is running.
2. Launch ODIN and configure it for firmware (we consider the options and options below).
3. Launch download mode on SGS.
4. Connect the SGS to the PC and make sure that the device is initialized by the ODIN bootloader using the indicator in the first slot.
5. Last parameter check, countdown, START!

The main files for SGS firmware are supplied as tar or MD5 archives. Actually, you need to indicate them in the appropriate fields of the Files (Download) section.

Let's first consider the simplest example - uploading factory firmware. Often this procedure is necessary, including before flashing a custom ROM, to prepare the file system. Typically, the firmware is supplied in the form of three files, the purpose of which is reflected in the name itself - PDA(or CODE - main firmware file), PHONE(or MODEM - the telephone part of the firmware responsible for working with the network) and C.S.C.— regional settings file. Also, when flashing stock ROM, you must have PIT file. I won’t tell you exactly what it is :-) But it’s needed! Apparently it stores service information necessary for the bootloader to flash ROM into the phone. Currently there are two such files for SGS: s1_odin_20100803.pit And s1_odin_20100512.pit. These files are usually loaded with ODIN or supplied with ROM files. The firmware description always indicates which PIT file should be used in a particular case. Here is an example of factory firmware delivery:

Next, as you can see, everything is simple, we substitute these files into the appropriate fields of the multiloader. This is what you should get after setting up ODIN and connecting your phone in download mode, i.e. just before pressing the START button:

click on the picture to enlarge...

After this, you can press the Start button and the phone’s firmware will begin. All stages will be displayed in the Message window. After successful completion of the firmware, the indicator in the slot at the top will glow green and display the inscription PASS. If an error occurs, it will appear in red.

At this stage, let’s immediately discuss the Option block, namely the first two checkboxes (I won’t say exactly what the third one means, it’s on all the time). First Re-Partition— allows you to repartition the file system from scratch, i.e. will completely erase the phone's memory and re-partition the partitions according to the data in the PIT file. Usually, when flashing a factory ROM, this checkbox is checked to avoid file system errors in the future. You will still lose all user data with the full firmware discussed above, so it should be checked. Next point Auto Reboot— when the firmware is completed, the phone will automatically reboot. Again, it should be checked when flashing the factory ROM.

In addition to loading the full ROM, using ODIN you can upload modified kernels, which are used to get root, replace the standard recovery (Samsung 2e and 3e) with ClockworkMod Recovery or SpeedmodKernel Recovery. We will talk about what recovery is and what its functions are later. Now you should understand that using ODIN, you can also upload not three but only one update file in TAR format, which is inserted into the PDA field of the multi-booter. With this type of firmware, you do not need a PIT file and you do not use it. Also, depending on the sequence described in the installation instructions for a specific ROM, you can/should clear the Re-Partition and Auto Reboot checkboxes. Why is this being done? Usually, before installing any custom firmware, you need to flash the factory firmware first. When you further flash only the update, you naturally do not need to repartition the partitions, because their integrity must be preserved. You may not need Auto Reboot when, after updating via ODIN, you need to not reboot the system but immediately go into recovery mode to complete the subsequent steps of the installation instructions. In this case, you simply remove the battery after finishing the firmware, insert it back and load the recovery mode.

Firmware and phone update via Recovery mode.

Here we come to the description of the recovery mode. What it is? This is the phone's service menu, called up in a way similar to calling the download mode, but in this case the volume button is pressed up. So, with the device turned off, press the volume up button, home, power on, hold until the phone screen activates, release. The splash screen will appear for a short time, after which you should see a text menu, usually on a black background, in green, red or yellow letters (it all depends on the current type of recovery). Navigating through the menu is done using the volume keys (up and down), selecting a specific item is the power button, returning to the previous menu is usually the last text submenu.

Using recovery, you can flash and update your phone with files in zip format. In this case, you do not need a PC. The main thing is to upload the update files to the internal card of the device in advance.

The simplest recovery is native Samsung versions 2e and 3e; these types of recovery come with factory ROMs. There are a minimum of points, one of them is “apply update.zip” i.e. The update file should be located in the root of the internal memory card (not sd) and be called update.zip. The update file must be signed and is intended specifically for flashing firmware through this type of recovery. This version of firmware is mainly used to obtain root rights on a phone with factory ROM and is used very rarely (possibly as an alternative to flashing the kernel with root via ODIN).

A more advanced type of recovery comes with custom firmware - this is ClockworkMod Recovery (called CWM on the forums). There are more items and expanded functionality. Using CWM, you can install any firmware or update file in zip format, which can be called anything you like and can be located anywhere on the internal memory card. Select the “install zip from sdcard” item, then the “choose zip from sdcard” item, in the primitive file manager that appears, find the update file and apply it.

In addition to the update functions, depending on the version and modification of CWM, the following actions are possible using the recovery menu and submenu: completely wiping the phone, clearing the cache, backing up and restoring data, clearing the battery log, managing partitions of system and internal user memory, partitioning the SD card and preparing it for apps2sd, creating a swap partition on sd, applying lagfixes and converting the file system to ext, enabling additional functions, such as backlit key notifications and much more.

One of the most common modifications of CWM for SGS is SpeedModKernel Recovery (SMK), which offers this expanded functionality compared to standard CWM; there are more points specific to SGS.

Example - the easiest way to install a custom ROM for SGS:

Many custom ROMs for SGS require SMK on the phone to carry out the installation procedure. This can be done directly on the factory firmware; you don’t need to get root, etc. first. - it's a delusion. The easiest way to obtain SMK one-time for subsequent update through this type of recovery is to flash the tar file with the SpeedModKernel kernel using ODIN (insert the file in the PDA field) with Re-Partition and Auto reboot unchecked. After flashing the kernel, you remove the battery from the phone, insert it, call the recovery mode and install any update, for example a custom ROM (the zip file, of course, should already be on your phone).

Some custom ROMs, such as CyanogenMod, require a more complex installation procedure that involves several steps of flashing the firmware via ODIN and SMK. Strictly follow the instructions from the developer and you will succeed! You are not the first, you are not the last! If you consider yourself a real geek, then you simply must master these simple procedures.

ATTENTION!!! The author is not responsible for the consequences of your actions with the phone after reading this article. It's not my fault if you turn your SGS into a brick! The official warranty for the phone disappears after flashing the firmware yourself. However, if something happens, with the help of the knowledge gained here, you can always flash the original firmware into your phone before going to the service center. If the phone is completely dead, no one will be able to determine what firmware is in it :-) make a face with a shovel and take it to the service center with the words: it’s broken... In any case, I repeat: only you are responsible for all your actions and their consequences! In fact, not everything is so scary and any incidents with tragic endings happen very rarely.

Happy firmware!

Samsung, it’s important to get a little familiar with the device itself. This way you can learn some useful things that you didn’t even know about before. Therefore, let's take a short excursion into the cosmic world of Samsung Galaxy devices - such as n9005 Note, n900, S3, N7100 and others.

Galaxy devices are very popular, stylish and high-quality gadgets

Samsung's smartphone market today accounts for an impressive share. The mobile giant in the modern world is the biggest competitor to another popular company that even children know about - Apple. And this is no coincidence, because Samsung presents to the public a large number of a wide variety of devices in all possible price categories. This, in principle, gives the company a certain advantage - the availability of devices for all segments of the population. If a person cannot afford a smartphone for 20,000 rubles, but he needs modern functions, then budget models can provide some of them. And Samsung is doing a pretty good job in this regard: the company’s devices in the budget price segment have a large number of necessary functions in their arsenal.

The most popular models are the Galaxy series. They include both premium smartphones S, S Edge, Note, and more affordable ones - A, Grand, Grand Prime and others. How do these devices differ from each other?

As you know, Galaxy S and S Edge are the company's top smartphones, which are released every year with new characteristics, functions and features, receiving a new number in the name (the latest version of the series is the seventh). Note is positioned as a tablet phone (a fairly popular word today), a device for business people or creative people. For those who constantly need a large screen, the main feature of this device is the S Pen, which allows you to create quick notes, sketches and other types of handwriting directly on the screen in various applications.

Grand and Grand Prime are positioned in the budget smartphone segment as the most popular. And this is not without reason: the devices have two cameras - front and main, a touch screen, support for high-speed networks, access to the global network, the ability to install almost any program (except complex games and applications) and use them.

Naturally, not all available Samsung mobile devices today were named above.

What do you need to know before flashing your smartphone?

So, if you are about to tackle this difficult task, then we hasten to make you happy. Because anyone can flash or reflash Samsung Galaxy (such as n9005 Note, n900, S3, N7100 and others). To do this, you just need to familiarize yourself with the initial data, some features, and most importantly, follow the instructions.

What might you need before you begin your mission?

1. The Samsung device itself with a charged battery (at least 80 percent). This is necessary to prevent unexpected device stops and further program failures.
2. Original USB cable for connecting to a computer. The cord is included, but if you don’t have one, you can use the one you have. However, it is worth remembering that such actions are performed at your own peril and risk.
3. Internet connection with unlimited traffic. This is needed in order to download the firmware itself, which can weigh more than one gigabyte. In principle, tariffs with limited traffic may also be suitable if this does not cause you any inconvenience. If you are unsure about your tariff, be sure to check with your Internet provider.
4. Desire and patience that will become your faithful companion. You may not be able to flash or reflash your Samsung Galaxy the first time. Don't be upset in this case. It’s better to try to carefully reconsider whether you did everything correctly and whether you could have made a mistake somewhere.

What are the firmware methods?

You can flash your device (Samsung Galaxy n9005 Note, n900, S3, N7100 and others) using both official Samsung tools and third-party utilities. Let's look at each of these values ​​and then move on to their instructions.

1. Firmware update using official software. This can be done from the smartphone itself, without using a computer or using it by directly connecting the device via a USB port. This is necessary for those who simply want to update the operating system version, for example, from Android4 to Android 5.0.
2. Flashing or flashing using third-party tools. The most popular service in this matter is the Odin program. It can be easily installed on a computer or laptop and is provided to users free of charge.

Official firmware update

Without using a computer

1. So, you have decided to update the operating system version of your smartphone without any cords or other devices, but only with the help of the device itself. Go!
2. Initially, connect to the Wi-Fi network. Without this there is no point in going further. If there is no access to wireless networks, but you have a computer with access to the global network and a USB cable, then move on to the next paragraph entitled “Using a computer.”
3. Now go to the “Settings” menu and find the “About device” item. Here we will need a tab called “Software Update”. Click the update button.
4. If your smartphone says that updates have already been installed on your device, it means that there are no available firmwares for your device. That is, the latest available version of the operating system is installed.
5. Otherwise, you need to agree to download the updates and wait for it to complete. When finished, click on the install button. After this, your Samsung Galaxy will begin a system update, during which the device cannot be used. Do not turn off the phone under any circumstances, do not try to reboot it or remove the battery - you can get a “brick”, that is, a completely inoperative device.
6. Only when you see the familiar home screen and a message that you have successfully completed the firmware update procedure, can you use the device as usual.

Using a computer

1. To work, you must have Internet access on a computer or laptop. Otherwise you won't be able to do anything.
2. Download Smart Switch software to your PC from the company’s official website (http://www.samsung.com/global/download/smartswitchwin/).
3. Now we connect the smartphone using a USB cable to the PC and wait until the device is detected.
4. The program itself will show you the availability of a new version of the operating system for the device in a special small window. If the outcome of events is positive, the “Update” button will appear, which you will need to click on.
5. All you have to do is wait until the updates are downloaded and installed. Installation may take a long time, so be patient.
6. As in the previous option, do not turn off the device under any circumstances or remove the cord from the computer. Ensure smooth operation of both your PC and phone to avoid unexpected breakdowns.
7. After a successful firmware update, you can continue to use your smartphone as usual.

What should you know after flashing?

Samsung, in its official manual (instructions) for upgrading the operating system, recommends resetting the data after such manipulations. Otherwise, Samsung warns of possible system failures. This will not necessarily happen to your gadget, but you can take it into account when you discover such problems in future work with your phone.

However, it is worth remembering that before resetting it is important to save all existing data: photos, contacts, videos, music, documents. This can be done manually, by simply transferring information to a computer, or using the Smart Switch utility, which allows you to backup data from a Samsung Galaxy n9005 Note, n900, S3, N7100 and others.

Firmware using third-party program Odin

First, familiarize yourself with the basic points that should never be violated. You have been warned about this several times, so that later you don’t grab your head and say to yourself: “What have I done?” Therefore, it is better to play it safe and carefully look at what needs to be done and what you are doing.

1. You perform all operations at your own peril and risk. This is the most important rule, because after flashing the firmware using an unofficial method, you will lose Samsung's warranty.
2. Do not unplug the power cord of your computer or laptop, that is, ensure unconditional operation of the PC.
3. Charge your smartphone at least 80-90 percent so that it cannot run out of charge during the update.
4. When connecting to a PC, use only the original cable.

Preliminary preparation and configuration of services

As you may have noticed, these rules are no different from the requirements for updating through official Samsung means, so you will have no difficulty in complying with them. Now let's move on to the most important thing:

1. First, download the Odin utility. It can be taken from the website (http://androidpru/odin-firmware-samsung/).
2. Now download the firmware file for your device to your computer. If you don’t know where to do this, you can use the Samsung Firmware Linker program, which allows you to find and download firmware specifically for your device.
3. Download the driver for your device to your computer. This is necessary for proper detection and configuration of the smartphone when connecting it to the PC. You can use the resource (http://androidp1.ru/drviver-for-android/).
4. Be sure to save all important data from the device to any other storage medium, just in case. Because when flashing, partial or complete loss of information from the gadget is possible.
5. The preparatory work is over now, and we are moving on to the main process. We put the phone into firmware mode. If you don’t know how to do this, then we try this option: turn off the device, hold down the volume down, center and lock (off) buttons at the same time. If it works correctly, you should go to a special menu, where using the volume up key you will agree to start in firmware mode. If you do not get to such a menu, then find this information specifically for your device.
6. If everything worked out for you, you can connect the device to your computer via USB. Wait a while until the necessary drivers are installed.
7. After this, you can launch the Odin application on your computer. In the left corner you will see that the gadget is connected, which means we are moving on.
8. Now you need to add the firmware files in the correct order. If for single-file firmware everything is very clear (insert the firmware into the AP or PDA field by clicking on the corresponding button), then with multi-file firmware you will have to tinker a little longer.

Multi-file firmware

Let's figure out which files need to be inserted into which field:

1. PIT is inserted into the PIT field.
2. tar.md5 - in BL or Bootloader.
3. File CODE_xxxxx.tar.md5 - in AP or PDA.
4. File MODEM_xxxxx.tar.md5 - in CP or PHONE.
5. tar.md5 - in CSC.

Continuation

1. Please note that you do not need to check any boxes on the left if the firmware itself does not provide for this.
2. After the correct installation of the firmware files, press the START button and wait until the program completes. After finishing, the word RESET or PASS will appear on the left. The device will now reboot and be ready to use again. You can disconnect your smartphone from your computer.

Conclusion

If after flashing or flashing your device you cannot turn it on (the so-called “perpetual reboot”), then try doing a reset. It is also known by its other name - Wipe. We hope that you will still be able to flash or re-flash your Samsung Galaxy n9005 Note, n900, S3, N7100 and others without any incidents. Good luck, dear readers!

I am the owner of the once top-end Samsung Galaxy S2. Lately it has started to slow down and become glitchy, which is why the question arose about rebooting and reflashing it. After re-reading many instructions with old and out-of-date data, I decided to write a short manual for everyone and myself too, from which you will learn how to reflash a Samsung Galaxy of any brand quickly and safely.

This guide was tested on all Galaxy models, from the second generation to 5. I also had a chance to reflash a couple of Note 2 and 3 versions. But you can also apply these instructions to other Samsung phones.

How to reflash Samsung Galaxy

To reflash the phone we need:

1. Required firmware. Download anywhere specifically for your model. If you need the Russian language, then the word SER must be present in the firmware name.
2. Program Odin_v3.09. Download.
3. USB Drivers so that the computer can see your phone via USB. We also download.
4. Data cable.

Instructions for reflashing the phone:

Step 1. Download the firmware (single-file with the extension .md5) and unpack it to any location.

Step 2. Launch the Odin_v3.09 program, click on the AP button and select our firmware. The program will check it for several minutes, then write in the status window (small white window on the left) that the check was completed successfully (Checking MD5 finished Sucessfully).

Step 3. Preparing the phone for flashing. We enter ODIN MODE. To do this, turn off the phone and after turning it off completely, press the following buttons together: Volume (down, down) + center button + on/off button (Power). When you see a yellow triangle, press the button Volume (more, up).

Step 4. We connect the phone to the computer via a USB data cable. The Odin program will recognize your phone and write Added in the status window. After that, press the Start button and wait 10 minutes while the program uploads the firmware to your phone and installs it.

Step 5. Once everything is ready, the phone will reboot and Odin will tell you that everything is ready.

That's it, everything is so simple and easy. This is what the program window looks like, with what you need to work marked in red.

If you want to reset all parameters and, so to speak, format the internal memory of the device in order to clear it of all junk and other files, then that’s a different story. I’ll say right away that it was this cleaning that helped me get rid of the brakes and lags of the device.

How to format Samsung Galaxy

The procedure is as follows:

1. Turn off the phone.
2. Press the following buttons together: Volume (up, more) - central button - on/off button. We are waiting for the menu to appear.
3. We move through the menu using the volume button, and confirm our choice with the power off/on button. We need a line Wipe data/factory reset. We reach it and choose.
4. Next, select Yes — delete all user data.
5. We reboot your phone by selecting Reboot system now.
