I don't understand what you mean with 'regained root'?
I translated it with google, but thats says: 'weather', so I don't think thats what you ment.
My ROM basis is the UK 2010 update from T-Mobile.
Now, I'm running just the original update from T-Mobile till this ROM fully works.
Thanks, and greetz,
Really strange problem, recommended wipe all and install from start. Is the phone also UK based T-Mobile?
