Well that didn't help at all. CM 7.0.3 crashed twice before I could even get into the apps drawer. Crashes all the same, probably more. Now, any tips how to get it back to how it was from the store? (I currently restored the backup of the original ROM I made with CWM) - how do I remove CWM (restore the original loader) and "unroot" it?
Uhmmm... CM 7.0.3 is old! Its the nightly 174 that should be used and is way better than the RC version.
As matter of interest did you do both a 'wipe data/factory reset' and 'wipe cache'.
That is a mandatory and necessity prior to flashing.
(Go into Clockwork, and there's two menu options as mentioned) Then all should be good after.
