You can flash the most recent version of clockworkmod recovery with rom manager but I suggest using the instructions here http://androidforums.com/thunderbol...91-how-some-root-terminology.html#post2812075 to flash the rom. I don't think rom manager will wipe all partitions that it should and can cause issues IMO
