Dead K9LAG08U0A PCB0, AK1025 player
 

I got a player from China yesterday, the simil square one with 5 keys. Turned on and it was working fine.
When i tried to turn on it today, i can see a flash white screen and nothing else (the screen remains black).
The same white flashes happens when i turn on the player. No hourglass, only a white flashes and the screen goes black......forever!
The chip is Samsung K9LAG08U0A PCB0, AK1025.
Can someone help me recovering this player?
My PC recognise it as USB 2.0 (HS) ADFU device, but i can not see it as a storage drive or with any firmware software.
Pls helpppp
Thanks in advance

Charge the battery.

Yesterday i charged the battery and the player turned on immediately.
Instructions says it must be cherged when is "on", but now i'm charging it and the player doesn't turn on, yesterday it does immediately.
Sure i have to charge it and it's not broken? For how many time i have to charge it?
Many thanks, and sorry to bother

If the device is getting recognized as ADFU it means the firmware is corrupted.

Open it up, post board ID and CPU.
