Reply with quote

I have a problem removing the mix from an SM324Q controller.

- Flash type (USB, CF, SD...) USB
- Controller name SM324Q
- Flash chips amount (2)
- Flash chip name and Config file content (Show config) -write next time (2 chips with 2 banks)
- Dumps amount 4
- Do you found FAT? yes. Once inverted.
- Is there mix? Yes
- Do you remove mix? that is where I have a problem.

I inverted the 4 dumps
I find FAT in 2 banks. In bank 1b and 2b.
Value pieces of FAT in these bank (eg. 0x13fb000-0x13fbe70) is this same. In 1a and 1b bank, in adress 0x13fb000 is pieces of dirs and files.


How do I get rid of this mix?

look for marker at position 512/513.
analize bloks with marker=0011.
skip bloks with marker=0044, 0045...

1. To get 300K use flash_Extractor:
-open file
-goto FAT
-press "copy" button, choose 300K to file

2. in 300K I see FAT tables with marker 0044
search for FAT table with marker 0011
for example: f8ffff/h/528/0
