4 Gb mp4 firmware extraction
 

I work repairing mp3/mp4 players here in Argentina. The last one i get to repair is a ipod nano clone of 4Gb. This is the firmware this one have.

2006/10/30
9.0.50
act2097_s72_1
2006/04/25

I get one working too, but i can´t extract the firmware of the workimg ome to put it in the dead one. The formware extractor show it to me like UNKNOWN (can read it but appears to be incomplete)

Anyone have the firmware to this mp4 complete? or something to extract the firmware of the working one? with the MP3 UTILITI4.05 i can write the device but with the S1FWX 3.1 i can´t extract the firmware.

Please some help here and thanks!

CoYoTe , S1fwx v3.1 does not support v9.0.50 yet. However, you can try using S1fash at S1mp3.de instead, it could extract the working firmware and memory files, and flash into the dead player.
