How to flash a tablet yourself

There may be many situations in which you will need to know how to reinstall Android on a tablet. For example, the system is working slowly and I would like to “refresh” it. Or you just want to upgrade to a new version of the operating system.

It is also possible to install Android OS on a tablet with Windows, but in this article I discussed flashing within one OS, namely from Android to Android. Reinstalling Android will solve most software problems, including viruses and various glitches. You can reinstall the system at home, absolutely free.

All you need to do is prepare the gadget, choose a flashing method and strictly follow the instructions.

Preparing the device

Before updating the system, the device's battery must be fully charged. If you will use a laptop or PC for flashing, you should take care of an uninterruptible power supply.

Losing power while reinstalling software can have catastrophic consequences comparable to corrupting the BIOS on your computer.

Remove the SIM card and memory card

We recommend that you remove the SIM card and memory card without fail. You never know what will go wrong. In addition, sometimes it is SD cards that cause system glitches.

Creating a backup

Installing a new Android will completely wipe the system, so first you need to create a backup and save all data to an external drive.

You can save the data to your Google account or any third-party storage device. Synchronizing with Google is the easiest way. Enabled in device settings. You need to select a work account and click “Synchronize”. When you log into your account from a new device, all data will be restored automatically.

The procedure for creating a backup is as simple as possible:

Turn off the device.
Turn on by holding Volume Up and Unlock key. Sometimes you additionally need to press “Home”. The exact combination depends on the tablet model.
Use the volume buttons to select “backup and restore” and confirm with the power button.
Wait for the backup to be created (this will take 5-10 minutes) and select “reboot now”.

If there is no such point, a system backup can be made using third-party programs. You need to install Titanium Backup (download from the Play Market), run the utility and provide superuser rights, then select “Back up user software and system data.”

Other feature-rich applications that you can use to create a backup:

ROM Manager. A manager with a large number of settings that provides convenient work with ROM files.
SP FlashTools. The professional program supports Chinese models of phones and tablets with a MediaTek processor.
Helium (formerly Carbon). A simple solution with convincing functionality. The set of copying functions is limited, but root rights are not required.

Firmware via computer

Using a PC or laptop running Windows OS, you can update the software of a tablet that does not turn on. The most convenient way is to download a special program. You can install the new version from the official website of the device manufacturer. Or by downloading from w3bsit3-dns.com specifically for your model.

Instructions:

Download the utility and install it on your PC.
Connect the tablet via a USB cable and select the “Software” mode. Some devices require a reboot after this.
It will search for updates in auto mode. If there are any, a window will appear with the “Start update” button active.

You can also update the firmware via a PC using third-party programs (the best ones are described below).

Necessary:

Install software that will update the device software.
Install the latest drivers on your PC.
Download the update file on the Android developer forums 4pda (site in Russian) or xpda (English).
Unpack the update into the desired directory. For example, when using FlashTool, it is recommended to unpack it into the program folder.
Launch and add firmware files. Scatter is always added first, which forms a list of the remaining software update files. In the Flash Tool, adding is done by clicking on Scatter-loading.
Connect the device to your computer via USB and start downloading. The update begins, after which you need to disconnect the tablet or smartphone from the PC and reboot.

With different device models, software and software versions, the update procedure is approximately the same. This means that after flashing, for example, Explay SM2 3g, you can easily reinstall the system on any other tablet.

Installing updates via wi-fi

After release, the OS update is not immediately available.

If after the release of the official update the system does not reinstall automatically, you need to do the following:

Erase application data to free up space so the update can install faster.
Connect to Wi-Fi.
Go to “Settings”, select “About tablet”.
Select “System Update” – “Check for Updates”.

This way, only official updates are installed, but not custom ones.

Update using third-party recovery

Every Android device, including the Samsung Galaxy Tab 2 tablet or Honor 8 smartphone, has a “recovery mode”. But third-party software has more functions and is much more convenient to use.

CWM Recovery

The latest version (6.0.5.3) is available in a standard version and an improved version with touch controls. In the first case, control is carried out using the volume buttons, and in the second - using touches. The modifications differ only in power consumption, the functions of the utilities are the same.

You can install CWM Recovery using special utilities (Galaxy Nexus, ROM Manager) or from the command line.

In the Galaxy Nexus Toolkit this is done like this:

Select tablet model and firmware.
Turn off the device and enter Fastboot mode by holding down the Volume and Power keys.
Connect to PC.
Press 6 in the Galaxy Nexus Toolkit (this is the item “Flash Recovery [CWM Touch, TWRP Touch or Stock]”).
Select CWM.

You can launch CWM from the OS using ROM Manager or through the Recovery item in fastboot mode.

TWRP Recovery

You can download the recovery from the Internet - there is an official TeamWIN page on the Internet.

This is how the software is installed on Samsung:

TWRP Recovery program.

Disable OEM locking on 2015 and newer tablets.
Download the Odin program.
Go to Download mode and select Twrp Recovery.
Connect your tablet and start updating.

TWRP can be installed on any device only through third-party ADB and Fastboot, the official Official Twrp App, Rashr, Twrp Manager, Flashify utilities.

ROM Manager

ROM Manager is the easiest way to update your tablet's operating system at home and with minimal experience.

Instructions:

Get root rights.
Install ROM Manager.
Create a backup.
Download firmware for tablet.
Select the “Install ROM from SD card” item in the ROM Manager menu and select the file with the firmware.
Wait until the procedure is completed.

The method works on Prestigio Multipad and other common tablet models.

A user of a smartphone based on Android OS, who already knows what to do if the phone does not turn on and how to see what firmware is on the device, also has an idea of the need to timely update the system version. This can be done in several ways - either directly on your phone or tablet, or using a computer. We'll talk about the easiest ways to update Android.

Firmware for tablet via SD card

You can use an SD card to reinstall Windows or Android on your tablet. Sometimes the system asks for root rights.

This can be done using programs:

Root Checker. Simple software for checking the presence and correct installation of superuser rights.
FramaRoot. Download and install the apk file into the device memory. The utility bypasses Android protection, so the built-in antivirus can block the software.
KingRoot. Suitable for most Android versions and mobile device models. To manage the acquired rights, you additionally need to install KingUser.

You will need Bootloader Unlock (there are program options for different smartphones and tablets: Asus, HTC, Samsung).

You can unlock the bootloader in another way, for example through a PC:

Get the unlock code on the manufacturer's official page. The code is available by IMEI or Product ID.
Connect your smartphone or tablet to your PC via USB and enable debugging mode.
Go to the Android SDK – Platform Tools folder. Hold Shift, right-click and select “Open command window.”
Enter the required command: fastboot flashing unlock for Acer, fastboot flash unlock unlock.bin for LG, etc.
Reboot or start the device.

Then you can start reinstalling Android:

Download the required firmware version to the DLOAD folder on the SD card.
Go to the “For Developers” menu. Enable OS installation mode.
Reboot the device in operating system installation mode (press the volume and lock keys).
After completing the installation of the system, you need to restart the tablet. The first switching on can take a long time - up to 10 minutes.

Reinstalling via a USB flash drive is more difficult compared to the procedure via a PC, due to the need to install additional software. But if the tablet or smartphone supports the built-in ability to reinstall the system, then dancing with a tambourine will not be required. For example, everything is much simpler on tablet computers running Windows.

Let's sum it up

You can update Android on your phone or tablet either using a computer or without it. The easiest and safest way is to install a new version “over the air,” during which the device receives data over the Internet from the manufacturer’s web resource. In addition, the owner can bring the system up to date by manually downloading the firmware and installing it in recovery mode or connecting the smartphone to the PC via cable.

Why do you need to reinstall Android?

First of all, the tablet owner needs to make sure whether it is really time to reinstall the operating system. Typically, this is done in several cases:

in case of malfunctions of the installed operating system;
to expand the functionality of the device, increase user privileges and the ability to install certain applications that did not work on the tablet before;
to improve security and privacy by removing a number of out-of-the-box features. For example, to disable the ability to transfer the device’s GPS coordinates, phone number and other personal information directly to Google servers without the user’s knowledge;
sometimes experienced users decide to replace the factory OS with so-called custom firmware, which is more convenient to use, uses fewer system resources and allows you to get rid of pre-installed applications;
If the tablet computer was purchased abroad (or through an “overseas online store”), it may not have the Russian language. Reinstalling the operating system may help solve this problem;
some custom firmware, in contrast to the standard pre-installed Android OS, gives the user more opportunities to personalize and modify the system to his taste.

If you decide to update or completely reinstall Android for one of the above or any other reason, carefully read the instructions on how to do it correctly.

If the firmware was unsuccessful

If problems arise after custom firmware at home, you can return the tablet to its previous state by updating again.

It is recommended to reset Android to factory settings. This can be done through the settings “Backup and reset” - “Reset settings”.

If this does not help or something went wrong during the software update, the lights are turned off, the battery is dead, the equipment shows no signs of life, is glitchy, etc., the best option is to take it to a service center. For a person without experience, resurrecting a brick can be a difficult task. But if you really want to, we recommend searching for utilities on the Internet designed to restore the boot sector of your particular tablet model. In general, you will have to read a lot of swearing for a long time. part and delve into the processes.

Why reflash your tablet?

You can independently reflash an Android tablet or even install Linux (and other third-party systems) through software updates, using the recovery menu or TWRP Recovery, via a computer and a USB cable.

The most common reason for flashing is a decrease in the performance of the device (i.e. the tablet freezes, glitches, sometimes the procedure is required after repair and installation of new hardware modules).

TOP 5 reasons to reinstall the system:

Get the latest version of the OS, with updated security packages. Some manufacturers end product support after sales. As a result, the user cannot update the system automatically.
Refusal of branded shells. Low-quality firmware from noname brands slows down the system. Pure Android shows record performance and returns to standard settings.
Removing pre-installed software and/or viruses. Reflashing will allow you to get rid of unnecessary software that aggravates the system, and the user can install Yandex or Yula independently.
Gaining access to engineering settings and additional functions. AOKR, Chinese Lewa and Oppo firmware are based on stock Android, but greatly expand the customization options.
Safety. Free software may be safer than Google's product. In custom software, you can enable parental controls or other options to protect data.

In some cases, for a tablet (if it does not turn on, slows down or does not charge, although there are no problems with the charger or port), flashing the firmware is the only way to bring the device back to life.

Few words

Many famous manufacturers regularly release updates for their devices, so most users do not think about how to reflash their device. The incoming updates are enough to keep the touchscreen computer in excellent working condition:

Minor improvements;
Error correction;
Changing the user interface and more.

This is what reputable companies do, however, there are also unknown Chinese manufacturers on the market who buy only in large quantities and very rarely accompany their devices. Their low price, relatively average technical characteristics and huge variety attract potential buyers.

However, for the most part, it will not be possible to update them via a computer or server to a new version of the system. More and more topics: how to flash a Chinese tablet appear on thematic forums - in this case, experts, alas, shrug their shoulders.

Risks

The initial stage of flashing the tablet firmware.
There are problems that you may encounter when experimenting with software updates:

The flashing process is quite simple, but with some degree of bad luck and inexperience, you can turn the device into an unnecessary brick with microcircuits;
custom firmware may not be optimized for the device, will quickly drain the battery or disrupt the operation of the navigator, blocking the signal from satellites;
new software can only partially support the technical part of the device, resulting in errors and non-functioning modules;
After flashing, the user loses the warranty.

It is worth updating the software yourself if you are willing to accept the risks. Without an understanding of how the software works and minimal technical skills, and without the desire to study the topic, it is better to entrust the flashing to a specialist.

In what cases is it necessary to reinstall the system?

Like any phone, all tablets come pre-installed with a specific version of the operating system. However, Google is constantly improving the Android OS, releasing newer and newer versions. They have expanded functionality, an informative interface, and have many improvements.

For these reasons, it is recommended to install the latest version of the OS. Some updates contain fixes for critical errors that may occur on specific device models. All these vulnerabilities will be eliminated by updating the operating system. Also, in case of glitches and slow operation of the device, a new version of Android can help you.

Clear signs that Android has taken off are:
