So I updated my flash partition with the latest SSU without problems and when I tried it on the mmc2 partition, I got "update error" -yet i didn't do anything to fix this.
I then tried to update my bootmenu and did so successfully a couple of times yet each time I try to boot into mmc2, the tablet tries but then finaly boots into flash.

I think I messed up bad the first time I flashed the bootmenu as I tried to reflash a bootmenu.conf I saved from pre-SSU.

I do have a backup of the mmc2 partition but would really appreciate not having to reclone the Os.

Any ideas of what I can do?
