A friend of mine who also has the DX is trying to .sbf to install CM7. He is still on Froyo as he never took the GB OTA. He's having an issue with RSD Lite. It won't recognize (connect) to his X. It's worked in the past for him so I'm thinking a different version of RSD Lite may not help. (he has MS Vista) Since he's still on froyo, would it really be necessary to .sbf? Maybe just a factory reset with a wipe cache and dalvik cache would work? Any suggestions?
