I am running a stock rooted 2.2 ROM and want to upgrade to 2.2.1 stock rooted. I used ROM Manager to install Clockwork Mod Recovery then I downloaded the FRG83D rooted ROM. I select "Install ROM from SD card" in ROM Manager and select Backup existing ROM and Wipe Data and Cache. My phone then reboots and the Moto logo comes up for what seems like longer then normal then the screen goes blank, the Moto logo comes up again for a long time and then the phone boots normally. It is still running FRG22. Any ideas why Clockwork Mod isn't backing up the existing ROM and installing new ROM?
