Answer 1

Can not access Android system

After press the power on key, it can show the “Android”. But it can not startup the Android

system normally, then stopped or reboot itself.

1) Check the energy the battery is used out or not. Try to charge the battery for some time

2) Try to reload the firmware.

3) Try to re-solder every Pins of the wireless Module.

4) Try to change the mainboard with another normal one to test it.
