How to flash tablet Android: methods and step by step instructions
Despite the fact that devices with Android OS have significant differences from a regular PC, they also require regular updating and reinstallation of OSes. This is required to optimize and improve the work of gadgets. But in some cases, the OS starts to “slow down” or works inadequately. To solve such a problem with the help of a normal reset is often not possible - here you need to completely reinstall everything. For this there are special programs and methods. Let's talk today about how to reflash the Android tablet and what it takes.
Types of firmware
Today there are two types of firmware: official and unofficial. The latter in the language of the inhabitants is also called custom. Official firmware have significantly lower performance and at the same time, unlike the unofficial, more stable. This is where the user has to make a difficult choice.But do not think that custom firmware is worse than the official, because they are productive and more saturated with useful features. So before you reflash the tablet, it is recommended to study the innovations in more detail.
Regardless of what firmware is used, it is required to use special software to install it. At the same time, it can be installed both on the tablet itself and on a PC, which will later manage the reinstallation.
In order to reflash the Android tablet, you can use several methods. The simplest among them are:
- firmware using Wi-Fi;
- PC firmware;
- firmware using a flash drive (self-installation).
Each of these methods has its pros and cons, which must be taken into account when reflashing your tablet. So, let's take a closer look at everything, which further allows you to freely install high-quality software on your gadget.
This method is popularly referred to as FOTA (OTA). Re-flashing using wireless is the easiest.In this case, you just need to agree with the proposal, and the OS will install itself on the tablet. There are also many disadvantages to this method. One of the most important is the ability to install only official firmware versions.
To activate the automatic update of the Android OS, you need to go to the "Settings" menu. Next, find the sub-item “Everything about the device” and check the box next to the “Software Update” checkbox that activates the function. If you decide to independently control the update, you need to remove the checkbox.
Unfortunately, this way it’s almost impossible to flash a Chinese Android tablet. The fact is that the producers of this country place the main emphasis on the release of new products, while the maintenance of an existing one is not carried out. In this case, you need to resort to the following method - installing the OS from a PC.
Re-flashing using PC
This method is perfect for those who want to install custom firmware. First you need to install special software on your PC. As such, they can be used as official programs from manufacturers of gadgets (practiced by Samsung, LG, etc.e.) and informal (created as a third-party product, but no less effective). For those who are thinking about how to reflash a tablet on Android, this option will be the most acceptable. Additionally, it is suitable for those cases where the gadget does not have a slot under the USB flash drive.
After installing the program, no matter which of all types you choose, the tablet will synchronize itself with the program and find the firmware versions. Then you just need to agree to the terms and accept them.
There are also options that require the presence of firmware on the computer. At the same time, the tablet must be disconnected and connected to the PC using a USB cable. Next, the program itself detects the gadget and offers to choose the location of the firmware. After specifying the address, you can agree with a flashing. This is how the Flash Tool, for example, works.

First you need to download to your computer the desired version of the firmware. It can be both official and custom.Next, you need to throw the firmware on the USB flash drive and insert it into the tablet. After such simple procedures, simply hold down the Home button and turn it off. If the first one is touch, then instead of it hold the “rocker” volume up. Hold until the green robot appears on the screen - the Android OS logo. Everything installation went. Now the main thing - to control that the battery does not sit down. If this happens, then there is a high probability of the ultimate "death" of the tablet without the possibility of recovery.
