How to reflash Android a phone or tablet if it does not turn on

There are several reasons why a device on OSAndorid may stop turning on: incorrect flashing, unsuccessful attempt to acquire ROOT rights, as well as any actions aimed at changing the OS system data. But all this in most cases is solved by a regular flashing, so I'll tell you how to flash Android if it doesn't turn on.

Solution

The problem is solvable, unless the bootloader is touched. You can make sure that it is operational by pressing the 'Power' button: the display should at least somehow react. It can be a lying robot, Android, or just an exclamation mark; all this will show that the problem is in the system, which means – in 90% of cases – there is nothing wrong.

Note: there were times when the display did not react at all when switched on. Then you should connect the device to the PC and try to press the 'Power' or 'Power' + 'Vol–' button: if the computer sees a connected new device, then there is also a chance to flash a dead Android.
