Hi Sergei,

When i try this, i get an error:

Canceled.
Data Corrupt: Fix Bank record format error

When i leave Fix Bank empty, i dont get this error, but all retrieved files are corrupt.

Any idea how to solve this ?

Thanks in advance,

Marc

Sergei,

In the mean time i found out that there are two memory-banks in the chip.
I mutated, split and joined each of them.
How can i make one file out of them now so i can process it further ?
What are the parameters i should use to join them ?

Best regards,

Marc

Solved:

I joined the two mutated dumps by 2112 blocks; then used the SM32xx utility with
Fix Bank empty, block size 42000, bank space 400, update size 1 and all builds True.

Using datarecovery software i could then extract the data from the image!

You read it in txt file?
We use this files for import and export.
You can import it at properties screen by pressing left arrow button.

In this case <Fix Bank: 0> mean: leave this field empty.
0 = 0 lines inside :)
Its format of export file :)

I think i send this txt file to you by e-mail.
I have 2-3 support cases at day.
I don't remember all details after some days.
And of course, after new year / chistmas holidays :)

Please use forum for support.
Even after some weeks i can see all history of questions and answers.
And if i absent my friend can help you :)

Repeat all steps carefully.
If i remember true, I do this and had success.

Don't repeat steps with new cards blindly.
As every time, you need:
- Find FAT.
- Remove mix
- Calculate Block_Size
- ...
