Since the phone won't turn on, the following recovery methods will cause you to lose data, please make a backup of your key data.

Local upgrade of SD card.

Prepare an SD card with a capacity of 2G or more to ensure that the free space is larger than the size of the upgrade package, and it is recommended to use brands such as Sandisk, Kingstone, or KingMax.

Plug in the charger, press and hold the volume up and down buttons, and press and hold the power button for more than 10 seconds to start the phone. The phone will enter the SD card to force the upgrade, if it will not be able to start because the battery is exhausted or the battery is low, charge it before upgrading to ensure that the phone can start, please insert the charger during the upgrade process, otherwise the upgrade will fail if the battery is insufficient.

After the phone enters the upgrade, the upgrade will be completed automatically, and the upgrade time is about 5 minutes, if the upgrade fails, you can try to try again.

If you can enter recovery, flash the machine; You can't just "save bricks".

After the copy is complete, you can disconnect the phone and the computer.

Turn off the phone first, then press and hold the power button and the volume 10 button at the same time to enter the recoveryr mode, the power button confirms the cursor, the volume button selects the cursor address, selects --wipe cache partition to clear the cache partition, selects --wipe data factory reset to clear the data partition and restore the factory settings, and finally selects the line with rboot to confirm the restart.

Generally, don't look for what is the cause of this situation, I don't know what the reason is without testing, so I try it directly with the following methods, such as electromechanical separation.

The phone can take off the battery from the boot to see if it is useful. Restore, restore, and see if this phenomenon still exists.
