Recovered 473MB, 3,174 Files in 183 Folders.
2-3 files are red, as there are about 10 conflicts.
The recovery is almost perfect.
Congratulations to you all. Very Happy





In FE V 6, Flash_Extractor_207.exe

First started with 01_01.dump.
FE detected
Model AU6986 ec d7 55 b6 1x1
Layout AU6986 528 (but all blocks red)
Assembler Block number

Layout SM3254 528 all blocks green

Block Pair 0x80000, 0x1000

Here I don't know how to split by dump+join by page, so I let it create the image.

Conflicts:
Image 0x0c400000 (00c4) Bank 00 Block 0c4
0x0c4 / 0x03000000 (0030) Block 00c4 ECC OK SA 2c c4 00
0x0c4 / 0x09500000 (0095) Block 00c4 ECC OK SA 24 c4 00

Image 0x85d00000 (085d) Bank 02 Block 0c4
0x85d / 0x83000000 (0830) Block 00c4 ECC OK SA 2c c4 01
0x85d / 0x89500000 (0895) Block 00c4 ECC OK SA 24 c4 01

MBR green, FAT32 red



Than tried with split by dump; 01_01.dump halves in new files;
rename halves as 01_01, 01_02.dump

It detects better:

Model AU6986 ec d7 55 b6 chips 1, banks 2
Layout SM3254 528
Assembler Block Number

Input 0/1
Block pair 0x80000, 0x1000
Join by Page 2, 0x2000



Assembler Block Number
Block Size 0x200000
Divide Block 1
Cross Block 1

But get MBR red
at 0x245a0000 do not find MBR

In both cases raw scan gives almost nothing, except several very small files.
