:) hi, this is a partial succes story ,i had a totally dead mp4 from ebay,china,(upgraded it with wrong firmware and never made a backup),anyway i have the new atjxxx chip so its been a problem getting it even to be recognised as a flash disk,but i finally did it after 3 days of looking and trying different fw.my chip is atj2093h it should be 4 gig but is only 2 gig. i installed firmware tool 4.07(from this site) then used firmware full ver 1.5 lcd 9.0.48(also from this site) now its just biding my time untill an updated firmware can be installed,im sure it will be upped soon on this site by someone, hope this will help someone get that little bit closer to fixing their mp4 too :)

WhatTheHeck. I may be new to this whole mp4 player thing but from what I gather from the rest of the forum it is not yet possible to extract firmware from devices with the 9.0.48 (or 9.0.50) firmware. I managed to do it with my player (9.0.48 firmware) but s1fwx won't repair the dumped firmware, therefore making it unusable.

You can try an s1clone dump, make sure it is empty of all files first so the dump will be smaller (s1clone dumps the entire contents of NAND flash chip).
