I have been rooted for a long time now. I was using clockwork recovery and BB.4 Froyo. I used RDS lite to get back to stock 2.0.1 and stock recovery. It worked flawlessly. The only issue is the phone is stuck at 2.0.1. When I go to settings and check for updates it says my phone is up to date. When I was running BB I did install a patch that would trick the phone into thinking it was up to date so I would stop getting the OTA notice. I figured this would be overwritten when flashing back to stock w/o root. I tried searching so if anyone can offer advice or point me to the appropriate post, it will be greatly appreciated.
