With:

Mix
Input
Order 0
Block Pair
Block 0xc00000
Page 0x4000
Assembler
Raw
Block Size 0x1800000


I get 79 good (big) photos and 3095 broken.

BP 0x600000 and 0x1800000 give worse result.

So still mix is not good. Maybe some cross mix or rotation inside block?

I found an SLC block, perhaps its a translation table? Can you see if your XOR magic can decode it?

Done Uploading...

Job.txt atatched

ECC Fix
ECC Off

Save Image
Make Raw Recovery

With Raw Recovery i get 578 good, 974 broken jpegs

Arvika have carver that can make better raw result

Result can be better
But need Block Cut
And may be Block Renum

Only 155 Jpegs are actually good, the rest are small or broken. Carver yields no better results.

Is this due to XOR step in the Mix not aligning up properly with Block Cut? What Block Cut value should I use?

But with Image Explorer Raw Scan you get 578 good?
Just to check if there is no errors

No

I dont know
It also can be Block Renum

Need more LBA patterns and cases with many FAT dirs
