I had the oddest thing happen yesterday! I've been running BB v.5 since it was released. It has been running flawlessly since install. Yesterday I rebooted as I usually do since it had been a week since the last time...and when it rebooted it was totally FUBAR'ed. Everything was force closing and I had the welcome screen wanting me to sign into my gmail account...it was like it had become corrupted or something. It would not respond to any inputs. I booted into recovery to restore a Nandroid when I realized I had never created one for the BB install so I had to revert back to an older LFY 1.5 Nandroid backup. So far it's running fine, especially since I turned off compcache. I've been rooted and running custom ROMs since the DroidMod days and have never had a melt down like this. Any thoughts as to why this may have happened, anyone experence a similar situation?
