Xor 21cd
Other parameters i dont know
Select layout
FC1178 1083_1079 Xor 21cd_128
Jump with block size = 0x2400000 down from zero
You will find many blocks that starts from zeros or FF
But at some place become random data
This looks like software bad bytes
But when i cut bytes at this place next data not become unxored (zeros or ff)
Software Bad Bytes
Block 2304
Group 1

New dumps uploaded...
I think FC1178 1154_1150 Xor 21cd_128 is a partial match.
You can see ExFAT headers here but no real data:
0x8555c000
Thoughts???
