great post! I didn't delete any apps, because I had read on another forum that deleting system apps had messed up a previous OTA for someone on a rezound. I just had frozen apps, so I'm going to try your other suggestion:
-reflash GB backup and take OTA
-restore current backup(dont reboot after)
-wipe cache and dalvik cache
I am thinking about using this opportunity to install another ICS rom, not sure if I want to install nils or a senseless ROM...hmm. I am happy with newts but I'm worried ROM won't be updated any further.
So I'm going to try ViperRez for now. Someone asked on the other thread which ROMS were based on the .12 software build. It's basically the ones that have updated in July, I think. So ConROM, nils business sense (Sense 4 version), viperrez, senseless chaos, neomax (senseless) and OTA-ICS-Plus (stock ICS rom with a couple of addons).
I am not sure whether newts one xxx 3.2.1 (6/30) or ineffablis deus (updated 6/26) are based on .10 or .12. Not that there's a huge difference but still...
EDIT: Guess I will be trying this method after all, as my GB backup didn't restore through Amon RA
