Re: Having trouble with a UBI filesystem

[Ron Bowes <ron@xxxxxxxxxxxxxxxxx>]

Hey folks,

Thanks for the pointers! I removed all the OOB data, which gave me a
pristine dump. I was able to extract other stuff (like the kernel and
boot image) once that was all removed. I also grabbed a clean dump of
the UBI filesystem, without all the OOB stuff.

Once that was done, I used ubi_reader to convert it to a ubifs (I'm
sure I could have done that with mtdtools as well).

Then I used this guide, pretty much as-is, to mount it:

Thanks so much for your help!
