At this time, yes, the correct size of dump was a little bigger than the one from NAND reader so I uploaded the bigger one. Sorry. Uploading FE dump with .bb file.

There is alot of bit errors

Can see them if select layout
AU6989 1146 Xor 6771_258 56-1

It not match by ECC, not match by XOR

But it can unxor first sector of page

MBR:
0x1bf78000

Sector with zeros after MBR:
0x1bf78200

Screen attached


And we can see alot of bit errors

There is no RR code for this chip
I dont know how to make read quality better
May be try read with different voltage

Sector Size 1150
Xor 6771

There is no such layout in FE
But i can not make new one, because of bit errors
