Layout
KMSJS000KA 62_1114 Xor v1

added to FE_1047

Only Xor and ECC

There is no Sector Numbers in SA
I think it is Translator Table based

Amazing job! I test on one case. With:

Layout
KMSJS000KA 62_1114 Xor v1
Mix
Input
Order 0
Block Pair
Block 0x100000
Page 0x2000
Assembler
Raw
Block Size 0x200000

I get about 50% good photos.

If need some more patterns to find TT let me know, I will prepare.
