Default Re: Can I recover my dead MP4 player with a backup firmware

dump.bin contains BRECF285.BIN and FWIMAGE.FW.
Code:
amy@box14:~$ fwx l misc/mpx/dump.bin
BRECF285BIN     00001000        00004000
FWIMAGE FW      00005000        00600000
-- BRECF285.BIN seems to be a valid boot record. I haven't validated the checksum though.
-- FWIMAGE.FW is 6MB of zeros.

Code:
amy@box14:~$ fwx l misc/mpx/QUART-M-450_ORG_BACK.FW
BRECF285BIN     00001000        00004000
FWSCF285BIN     00000000        00000000
ADFUS   BIN     00270600        00002400
HWSCAN  BIN     00000000        00000000
FWIMAGE FW      00005000        00854a00
It seems you're missing FWSCF285.BIN and HWSCAN.BIN, both entries have 0 offset and 0 size. FWIMAGE.FW appears to be valid though.

The same situation occurs with QUART-M-450_MODED.FW
Code:
amy@box14:~$ fwx l misc/mpx/QUART-M-450_MODED.FW
BRECF285BIN     00001000        00004000
FWSCF285BIN     00000000        00000000
ADFUS   BIN     00270600        00002400
HWSCAN  BIN     00000000        00000000
FWIMAGE FW      00005000        00854a00
Also, what version of s1res are you using?

important bugfix: firmware import produced invalid-brec
This may be the cause of your problem. If the BREC is invalid, the BROM will not try to run it but go into ADFU mode immediately.
