There's no point for me to go into my backup as the only back up I have on my phone is one I did earlier before I started messing around with trying to install new ROMs, so I'm still stuck. Who would have thought trying to install 2.2 on a rooted phone would be so difficult, I've literally been at this all day. Trying RUUs to flash it back so it wasn't rooted. All was well until I got an error trying to install it "error[140] Bootloader version error".

I'm nearly giving up with this, I really wish I hadn't have rooted my phone so I could have just got the update normally like everyone else. Instead I just get a signature verification error.
