Hi Sergey,
A little help please..
I just got my reader, and managed the first recovery on my own, a 512Mb stick based on the OTI 1002168. A simple read, and convert to disk image.
But I now have two virtually identical Sandisk 4Gb drives.
The nand chip is SDTNKLCHSM-4096.
Which cfg file do I need for this? Or what configuration data?
I used SDTNIGHSM-4096, amended to 4096Mb and changed ID to suit the ID read from the chip.
But the data don't look right, no FAT and loads of verify errors. Same on both chips I tried.
edit: Just noticed that every other byte is "00"
Both chips are clean.
Thanks!

Select cfg file.
Right click -> Show config.
Copy log to forum.
Show me log of Read_ID in 1,2,3,4 banks.

I made the modification to reader.
Still show many, many errors on verify.
Still not looking good 
| Code: |
Read_ID 45 b7 96 e5 Error
Start 0x0
End 0x108000000
Size 0x108000000
Block 0x0
Verify...
Diff: 00042000
Diff: 00063000
Diff: 000c6000
...etc...etc |
I read the chip two times, and compare reads with Winhex. Both same.

Yes I did add wire. Join bottom empty connector to pin next to it.
Picture below, is correct?

Enachnt is correct.
Attach 300k from any dump place with data.

Here it is..

Is it normal also, to get so many differences in verify?

oh...this SunDisk....
Every time they make something special :)
Dump_Converter / Swap
Swap_Size = 1
Try find FAT
if yes, attach 300k

I've now swapped words in the dump, looking a bit more like data.

P.S. This 300K dump is from the beginning, not from where "FAT" is found. If I try to dump from there, it actually dumps 310K and will not ZIP or RAR to less than 304Kb!
