If your tablet begins to lose its functional potential, frequent errors occur in work, braking and other unpleasant moments - it's time to think about flashing the device. This process is forces to implement each user. In this post you will learn how to flash the tablet on Android in various ways. The article presents the mass of tips on how to firmware gadgets. Given these recommendations, you are guaranteed to flash without the "skirting" and many other errors.

What is the firmware and why it is necessary for the device

The firmware is called the operating system, which is preinstalled on the gadget. The purpose of the operation of the OS is to adapt the work of the mechanics of the device directly under the tasks that the user puts.

Without firmware, your multifunctional device is an ordinary mechanical unit that cannot even perform the calculator functions.

Varieties of firmware

Almost every year, Google pleases the admirers with new software versions, significantly expanding the user's capabilities. Android 8 Oreo appeared on the market, although many more manufacturers have just begun to adapt the software shells of their products under Android 7 Nougat.

It should be completed with the fact that progress does not stand still, and every year manufacturers will delight us with something new in terms of software products.

At the same time, practice shows that it is possible to classify the Android firmware not only in the growth line. Today the firmware market is divided into original and custom. Many enthusiasts and whole companies systematically work on the manufacture of their platforms for different versions of Android OS. The varieties of firmware on the market every year becomes more and more.

When the Android tablet firmware is required

The reasons for flashing the gadget is an impressive set. The most frequent of these include systematic hangs of the device and braking. Due to the appearance of new OS, manufacturers of applications and games increasingly began to forget about the support of users of old gadgets. Hence the result in the form of constant departures, hanging and unstable OS. The problem solves the firmware update to a more recent version.

Another common reason to install Android firmware on the tablet of a newer version is the desire for new features. Each Android OS gives a new, richer functionality.

For example, Android 7 Nougat pleases the user with a multi-color mode, and MarshMallow compared to previous versions has an intuitive interface setup for any user needs.

Android tablet firmware options

Inteblishing the firmware closest process, you will familiarize yourself with the four ways to update software, each of which has its own characteristics and disadvantages.

We are talking about updating:

• "By air";
• through PC;
• through recovery;
• via SD drive.

The firmware for the Android tablet can be carried out by any of these methods. The main thing is to take into account certain criteria when reinstalling the system. These include the availability of the firmware functional archive.

Swing only from proven sources. If you use third-party PC hardware, make sure that the installed current version of the drivers and a good USB cable are installed.

Separate attention to share the battery. The energy accumulator must be at least 50%. Otherwise, the installation of a new software can stop at the most inopportune moment and the gadget "snaps up."

Fota Firmware Update

Update "By air" (FOTA) is provided in almost every android device. The utility that is responsible for the firmware is sewn into the structure of the software.

The essence of the process is that the user independently checks the availability of the official firmware from the device manufacturer. It requests the manufacturer servers to search for a fresh firmware version.

If the software is found, it remains to give good to install. When using the update "By air", you should connect to a free Wi-Fi network. Otherwise, mobile traffic will be charged.

The most universal method of firmware of multifunction devices based on Android OS is rightfully considered an upgrade through a PC. At the same time, each user should be extremely attentive, because how to properly flash the Android tablet through the computer is not written in every article on the Internet.

When firmware, the gadget takes into account the most different parameters from the manufacturer of the device and ending with the presence of custom and original archives that can give those or other users.

Separate attention deserves and the variability of firmware using PC. At the moment, the Android tablet firmware through a computer, via USB can be carried out when using additional software from both official gadget manufacturers and third-party developers. On the open spaces of the global network, there are many utilities that allow flashing devices through a PC using a wide variety of principles.

A fairly convenient way of firmware of the device is the installation of the latest version by the recovery menu. This procedure allows you to reflash Android on the tablet through the tablet without using additional software or equipment.

For this you need to follow the two main conditions. First of all, you need to download the firmware from the official site of the gadget manufacturer or from other proven sources to your tablet. Then move the archive to the root directory of the gadget and go to the recovery.

For each device, the transition to the menu assumes its key combination.

Using an SD card

An equally popular method of firmware, which we will touch in this post is the installation of software through an SD card. This firmware method also implies the use of recovery, but it has a number of significant differences.

Initially, the firmware of the device moves to the SD-drive, and the entire installation process runs from it. This method of firmware is perfect for users with "skipped" devices that cannot download the firmware directly or do not have the ability to connect the tablet to the PC, for example, due to a faulty USB module.

Data backup and old firmware on Android

Interested in the issue of software updates on the tablet, take care of creating a copy of personal information in advance. We are talking about programs that subsequently allow you to make a backup firmware from the cloud.

The need to create a copy of the data is due to the fact that not all firmware are installed smoothly and subsequently work without failures. In fact, creating a copy for a backup allows the user to protect yourself.

The tablet does not turn on after the firmware update

Any manipulation with the firmware can lead to serious problems, up to the fact that your gadget will stop switching on or reacting to the commands set. Practice shows that not only the owners of tablets are facing such situations, which decided to update the firmware using custom archives, but those who preferred official assemblies.

You should not panic when these situations occur. It is better to immediately get acquainted with the options for the exit of the current situation.

Restore the standard parameters of Android firmware

If you do not have a desire to reflash the tablet, but you are faced with a number of problems affecting practicality and efficiency during the work, try to restore software to the initial indicators.

It often happens that the manufacturer of gadgets with each version of the Android versions ceases to support one or another phone or tablet. Also the user can wish to return previous versionwhich he liked more. Or the device stopped turning on. In this case, you need to know how to flash the Android tablet through the computer yourself.

How to update the firmware on the tablet

Consider this issue on the example of Oysters T72 3G. Before starting to conduct any manipulations that affect the firmware on the tablet, you need to make sure that the following conditions are followed:

1. Oysters T72 3G tablet has a battery level of at least 50%.
2. The computer installed the SP Flash Tool program.
3. File with firmware in advance downloaded.

The firmware update file is preferably downloaded from the manufacturer's official website. After all the preparations are made, you can start an update:

• the device is turned off and connect using a cord to a PC;
• click on the "Reset" button, which is located near the power button;
• now run the program SP Flash Tool;
• in it, click "Download Agent", while the folder will open in which this utility is located;
• we find a file with the name "mtk_allinone_da.bin" and open it;
• now in the utility window, click on the "Scatter-Loading" button and in the window that opens, we find and open the folder "FW_ROM";
• it requires a file with the name "MT6582_Android_scatter.txt";
• after that, the Utility window opens a list of modules on the tablet;
• to select the firmware mode, you need to select "Firmware Upgrade" in the drop-down list;
• click "Download";
• once again, check whether the tablet is connected to the PC and click on "Reset";
• reflash.

If the process has not begun, you need to press "Reset" again. If the Android on the tablet has been updated successfully, a notification will appear in the utility window. After that, you need to disconnect the device and press "Reset" again, but only for a second, and then turn on the gadget.

The most important condition for all this procedure is in no case to disconnect the device from the computer, otherwise all actions will have to be repeated.

Install the desired version

Before reflashing android using a computer, it is necessary to make a complete backup system. This applies to both updates and return to any previous version.

Consider how to flash Lenovo A3500-H tablet through a home PC. The difference in this case is only that the Lenovo A3500-H can be downloaded to any version of the firmware, even alternative. Just for security, the source site must be verified.

To change the version of Android on Lenovo A3500-H, you will need the same SP Flash Tool utility. On the way to the folder where the downloaded file with the firmware will be located, you can not use any unnecessary characters and letters of any other alphabet, except English.

Procedure for installing the desired version of Android on Lenovo A3500-H:

• we repeat 3, 6 and 7 actions from the previous paragraph;
• be sure to enable the DA DL All WITH CHECK SUM option to avoid the possibility of turning your gadget in "Brick";
• in the Options menu, we also definitely turn on USB MODE and DA DOWNLOAD ALL;
• click on "Firmware Upgrade";
• now you can connect the device turned off;
• after notifying the success of the operation, you can disable your Lenovo A3500-H and use.

How to flash a chinese tablet

Problems can create not only chinese phone, but also a Chinese tablet. The thing is that with different system errors or refusal to work at all, the owner will have to spend quite a long time to search for the desired version of the firmware. It is also necessary to have a special bootloader to transfer the firmware to the memory card.

To make your device more workable, you need:

• find the file itself with the firmware, for which in the search engine it is desirable to drive the exact name of the model;
• a separate memory card (no more than 2 GB) in advance in FAT32 format, and then throw this file to it (it is better to do with a PC or laptop with cards);
• fully charge the device;
• insert the prepared flash drive;
• turn on the device again;
• the firmware will automatically boot, after which the flash drive must be removed;
• we overload the tablet and check the result.

In case of unsuccessful firmware

It also happens that the devices are reflashing, but the result from this is deplorable - it starts the problems in the work or it simply does not start. In other words, the user received the usual brick.

Android is an open source system. Developers can modify software, add new features and create your own images. Any user can install a third-party firmware on its device. Today we will tell how to reflash the tablet on android.

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

The most common cause of flashing is to reduce the performance of the device (i.e. the tablet freezes, it is buggy, sometimes the procedure is required after repair and installing new approxtent modules).

Top 5 reasons Reset the system:

1. Get the latest version of OS, with updated packages of the city. Some manufacturers are completing product support after sale. As a result, the user cannot update the system automatically.
2. Refusal from branded shells. Noname-branded non-quality firmware brakes system work. Clean Android shows a record speed and returns standard settings.
3. Removal of pre-installed software and / or viruses. The flashing will allow you to get rid of unnecessary software by aggravating the system, and to install Yandex or Yula can the user can independently.
4. Access to K. engineering settings and additional features. AOKR firmware, Chinese LEWA and OPPO are based on stock android, but strongly expand the possibilities of customization.
5. Safety. Freely distributed software can be safer than a product from Google. In user software, you can enable parental control or other options for data protection.

In some cases, for the tablet (if it does not turn on, it slows down or is not charging, although there are no problems with the memory and port) flashing is the only way to return the device to life.

Risks

There are problems with which you can encounter when experiments with update by:

• the flashing process is quite simple, but at some degree of unsaturation and inexperience, you can turn the device into an unnecessary brick with chips;
• custom firmware may not be optimized for the device, will quickly discharge the battery or disrupt the operation of the navigator, overlapping the signal from satellites;
• new software can support the technical part of the device only partially, the result - errors and non-working modules;
• after flashing, the user loses the warranty.

It is worthwhile to update on yourself when you are ready to take risks. Without an understanding of the work of software and minimal technical skills, in the absence of a desire to study the topic, it is better to entrust the flashing by a specialist.

Preparation of the device

Before upgrading the system, the battery device must be maximally charged. If a laptop or PC is used for flashing, you should take care of the source of uninterrupted power supply.

Disable power during reinstallation of software can cause catastrophic consequences comparable to the damage to the BIOS on the computer.

Remove sim card and memory card
