Gentlemen,

I'm sorry to disturb you again. Fighting with a strange dump from a broken USB stick:

Controller:
SM3257EN L
-AA 1130

FLASH Memory:
Flashbay.com (instead of TOSHIBA)
TC58NVG6T2HTA00
0x98 DE 98 92
WL + DDR (SDR: "stripes" of 0xFF in dump)
Power mod: 1/0x80ac

Could you please check the dump for XOR?

Thank you very much in advance!

Thomas

Dear Sergey,

it works. Thank you so much!
You're the hero!! Very Happy

Block Mutate
Block 9216
Cut 0/0x60

means, remove leading 96 (0x60) zeros from each block, right?

Kind regards,

Thomas
