I am not rooted. I have stock recovery. I was running clockworkmod recovery and buggless beast. I used rsd lite to flash to stock recovery. I tried to to do a manual install of official 2.2 and I get an error that says failed to verify whole file signature installation aborted. I tried several different download mirrors, made sure the file was named correctly update.zip not update.zip.zip I have no clue what to do. I don't know if the ota update will do the same. I would prefer to get it installed without having to wait any longer. Thanks in advance. Also I hope this is in the right spot.
