Recovery Guide not working
 

Hy,
I bought a fake 8gb MP4 player on ebay (Chip SAMSUNG 713K9LAG08UOM PCB0). After Err disk problems, reformating (FAT 32) to 2 or 4 gb (do not exactly remember), the system is not blocked (blue screen with waiting signal).

I try to reset the system using the dead recovery player : when touching the chip pins, I can hear some bips (bip and boup), but the PC do not recognize the MP3 player. What am i doing wrong ?
What can I do more ?

1.The flash u have is 2GB.
2.try format in FAT system.
3.while doing short circuit recovery, battery must take off from PCB. accurately, short circuit between the flash's 29~32pin(count anti-clockwise from the round dot of the flash),keep holding and connect USB.do not short circuit pin 12,13,36,37,u may kill the flash memory chip.
