I bought this unit in a non working condition. After trying to reset the unit (ak1025 pin 6) for 1000 times, the player came back to live two times!! That's were I was able to wrote down the firmware data:

But after powering the unit OFF, the player starts allways stucked with a "loading" message...
So I decided to stamp a new firmware to the unit, but I still can't recover it. (By the way, I was unsucesfull on triyng to backup the existing one..)
Have no problem with the flash, I'm able to access it, have formated it twice under fat and fat32, place some songs, etc. Also can access the device as an ADFU 2.0 device!
All this firmwares have been stamped, but none of them have worked!!
With this only one, the display flashes twice, the remains off, and I'm able to use the the unit as a pen drive.
