Half-Dead Tylex MP4 player

[arzakem]

Hi. Merry Christmas. Its a bit tasking that I seemingly brought my brother's Chinese made TYLEX MP4 (1 gig with FM) to its doom by flashing it with an upgrade. Now whenever flash it with different firmwares from the download page, I get the following results:

result 1: only a blue background with hourglass; USB drive not readable
result 2: only white background; USB drive readable
result 3: white background that responds to button press; USB drive undetected
result 4: white background with clicking sounds; USB readable

I provided the pics below of the MP4 and I dont know what's the best flasher tool or firmware version for it. I have already used Upgrade tools 3.68, 4.12, 4.15 and finally 4.05.



Any suggestions please? Thanks a million!!
