According to the latest statistics, the number of sold tablet computers is increasing every year. The reasons for this are very different: the balance between the dimensions and computing capabilities of devices; absolute silence during operation, no additional components (keyboard and mouse); energy efficiency; high reliability due to the absence of moving parts. However, if there are no questions with the first points, then with the last one, everything is not so simple.
Now on the market there are a huge number of inexpensive tablets from Chinese manufacturers that are not distinguished by too high build quality, which sometimes leads to certain malfunctions. In some cases, you can’t do without contacting service centers, and sometimes it’s enough just to find information on how to fix a tablet at home and apply the knowledge gained in practice. Surprisingly, most often you can "lift" the device yourself, saving money and time. The main thing is to constantly remember that the answer to the question “is it possible to fix the tablet” is always in the affirmative, but you should not even start without faith in yourself.
Diagnosis
Any repair starts withfault definition. All of them can be conditionally divided into two categories: software, in which, for one reason or another, a “software” failure occurs, as well as hardware, when any internal electronic component fails. Depending on this, the approach to repair also differs.
The probability of self-recovery is higher when it comes to a system error. Although in the first case, you can fix the tablet. A broken screen is one of the most common breakdowns that can be fixed without outside help. To do this, you should decide on the designation of the display, which is indicated on it, order a new one and replace it. Note that models listed as compatible may not work in this configuration. Therefore, a 100% match in designation is desirable. If the operation of the tablet is disrupted due to updating system files, obtaining root access rights, attempting unsuccessful firmware, then, unequivocally, the problem is software, which is solved by returning the file system to its original state. This type of error occurs most often. Consider how to fix the tablet if it does not turn on.
Preparation
In order to restore the functionality of the tablet computer lost due to a software failure that caused the inability to boot or any other similar troubles, you need to download the Flash Tool program to your computer. In fact, it should be familiar to anyone whoat least once wondered "how to fix the tablet." This application is designed to work with processors from MTK.
Next, we will talk specifically about tablet models based on such computing cores, since they are the most common. It is recommended to refuse old versions of the program, since compatibility with new models may not be ensured in the proper amount. It is worth paying attention to version 5.х.х. This software solution allows you to write new system files to the internal memory of the device, i.e., perform the so-called flashing.
System Dial
You also need to find and download the firmware archive to your computer. It is a set of system files, usually distributed in a single archive. It is important that it is intended specifically for the tablet model being restored, including its revision.
It is best if the firmware is obtained from the device developer's website. So, for example, for the Oysters tablet, you should not look for a suitable product on network resources from Apple, Lenovo, etc. Also, do not ignore the possibility of searching for the desired software solution on specialized forums if the model is not supported on the official website for any reason. And finally, you need a cable that allows you to connect the tablet to your computer.
Define modification
It often happens that two seemingly completely identical devices actually differ. For example, a manufacturer, when assembling a new batch, may startinstall another type of display matrix in the tablet, similar in characteristics, but controlled by other drivers. Accordingly, two revisions of the same device will appear on sale, differing in the driver embedded in the firmware. Thus, anyone who wants to figure out how to fix a tablet is simply obliged to correctly determine the modification of the gadget.
If the system's performance is not completely lost, then this can be seen in the "About phone - Build number" section. For example, in one case, the version is SA0001, and in the other SB0001. In such a situation, firmware from one device to another will not work. The modification is also indicated on the board, which is very useful if the device does not start at all.
New system boot process
Archive with firmware must first be unpacked into a folder containing only Latin characters or numbers in the name. Then run Flash Tool. In this program, select the scatter file, and MTKxxx.bin, to specify the paths to which a dialog is displayed. The flashing mode must be set to Download. After that, you need to press the green button to start the process and connect the tablet to the computer. If everything is done correctly, the system will start booting to internal media.
Food
The case discussed above with the loading of new control programs is, so to speak, an ideal variant. Although service centers require impressive remuneration even for such work, there is nothing complicated inthis is not the case, unless, of course, a suitable firmware is selected, and the failure is software. But how to fix the tablet if it does not turn on due to a completely “dead” battery? In this case, any attempts to turn on the device are useless, and connecting the charger does nothing. In fact, this is not a breakdown, but a feature of work, which also applies to smartphones, registrars, etc. The reason lies in the features of the charge controller that controls the filling of the battery with energy.
How to fix a tablet that turned off and won't charge? With a regular plastic card with sharpened edges, you need to disassemble the gadget's case and get to the battery. It is usually connected to the main board with two wires through the block controller. Most often it is black ("minus") and red ("plus") cores. You need to take any charging unit that produces the desired voltage (current - preferably at least 1 A), and determine the polarity of the wires - often it is indicated directly on the case. Then unsolder both battery wires from the main board of the tablet and wind / solder them to the wires from the prepared charge, observing the correspondence. In this case, the block should heat up (up to 50 degrees) depending on the parameters. When finished, the controller will abort the process and the temperature will drop. The wires can be soldered back and the tablet can be assembled. If the problem was over-discharge, the device will turn on and be fully functional.
How to fix a broken tablet
Perhaps thisone of the most difficult breakdowns. If the repair is expedient (the device is not smashed to smithereens), then you need to carefully examine the damaged element and find a designation on it, which is a set of letters and numbers. Then, having this data in hand, order a replacement. In this case, every character is important. In fact, there is nothing complicated about how to fix a tablet. One of the conditions for the successful completion of this operation is the correct selection of programs (in case of a “software” malfunction), as well as the exact identification of component models by designation numbers - if the failure is hardware.
