now it is keeping flashing power led, the progress bar does not move.
sometime it will reboot itself and loop back this keeping flashing power led with no progress bar forward.

I have tried many method of recovery.
1. pressing next and back button during first time show "opening book..." but no progress bar moving.
2. use sd rescue in microsd and press home and menu during first time show "opening book...". There is progress bar moving but keep stuck in completed progress bar page. After reset the device back to the original problem.

I have tried "rupor-rescue.7z" and it is ok to use putty to control my device but still cannot recover it.

what should i do? any suggestions?

actually i just brought it to about 3500m mountain and after return to ground, i found the device turn on by itself and out of power finally. after charge up and reboot the problem shown in youtube is there.
