Hello guys,
I've bought two mp4 digital players from china,they are both supposed to be 8gb,thought i don't think that's the real capacity of the flash memory,as on memory chipset the only writings i can see are 1GAAA,so probably 1GB.
By the way,this is not the problem i'm facing.
I tried to upgrade firmwares on one of the two players,before doing that i used the s1fwx tool to backup the original firmware.
The backed up firmware has checksum errors,most of the FWIMAGE.FW files are empty,and after the "s1fwx f" command the player didn't work properly anymore,even if i still hadn't tried yet to update the firmware.
If i tried to back up again an error occured,the s1fwx was unable to switch "f-mode" on the device anymore.
So i updated firmware,and now the player is dead,i tried recovery mode with many firmwares but none of them worked properly.
I tried even to backup firmware from the other player,still with s1fwx,but as it happened with the first one,the backup was almost empty,and now even that player does not work properly as it used to.
So,i hope someone can help me,looks like the s1fwx is not working properly with my devices cause it fu*ks them up,btw i will include all the specs of the player,which is a black fake nano:

SCREEN cm60009act6 20060705 {1.5'}
MEMORY 1GAAA
CHIPSET ATJ2085H {F8160AB C8P}

If anyone can help me plz contact me on MSN/email "giacomomargaria@hotmail.com".

I need a firmware to have the players back working.
I have pics of the player and some screenshots taken from the original firmware i'd be glad to send this stuff via mail or msn to everyone who's interested in helping me.
Thank you very much in advance.
Bye
