I still don't get which Image is the right one.
I gave image-168167.bin a try, but it contains many errors, I'm not sure
if it contains the first error.

So, which file do I need to download to get the image that contains the first 
error as detected by chk_fs?

The mode of operation of your tool should be:
1. Mount UBIFS
2. Do various filesystem operations
3. Random power-cut (in software)
4. Dump the image to a file X
5. Set chk_fs to 1
6. Mount it again
7. If mount succeeds, drop X, umount and goto 1
   Else if, chk_fs finds a problem. Store file X.

I want file X. :-)

Thanks,
