Solutions to tablet computer crashes:

1. There is a hardware problem. If there is nothing you can do, call the manufacturer for repair matters!

2. System problems, the solutions are as follows:

First of all, try to restart the tablet, first check whether the tablet has power, and if it is out of power, charge it first.

The most common solution to the problem of being unable to boot after a crash:

You can try to use a long and thin object, such as a toothpick or ballpoint pen, insert it into the RESET port on the tablet body, and then try to turn it on. If booting is unsuccessful, you can try plugging in the RESET port again and try again. In addition, you can also try to press and hold the power button for more than 10 seconds. Some models need to press and hold the power button for a long time to restart. If none of the above methods work, it is recommended to try other solutions or contact the manufacturer’s after-sales service for help.

Flashing your phone is actually very simple. If you are not sure about your operating skills, you can also spend 50 yuan to find a professional in the Computer City to help you flash your phone.

General flashing steps are as follows:

① Go to the official website of the product to download the firmware package for the corresponding model (go to the official website of the brand of your tablet)

Normally, the firmware package will contain multiple files after decompression, including a flashing tutorial. Just follow the tutorial. If you have any questions, please consult the manufacturer’s after-sales service or other machine friends.

Note: The flashing method and firmware package of each brand cannot be universal. Do not use third-party software to flash the machine. Only use the official software and methods. It is recommended to flash the machine on WIN7 and XP computers, as it is easier to install the driver. To flash WIN8, you need to turn off the driver to force signature first.
