I applied 2.2.1 yesterday but lost root access. For some reason I cant get root access back. I have tried doroot and the one click root and neither one of them seem to root. I have a full nandroid backup but cant access it since I dont have root access anymore so my bootstrapper doesnt work right now any ideas on how to get root access back? I didnt use the update.zip method so I think my update.zip would be my original...dont know how that works, did it get replaced with the new version when I flashed it over? I guess I could experiment with the stock bootloader and see if it flashes back to 2.2 I just hate not having root access because now I am kind of limited on what I can do
Do not try to restore a backup from 2.3.15. This will probably screw your phone. Download z4root.apk from link below. Put apk on sd card. Click on apk and install app and data
