my buddy got a used optimus m on 2.2.1 and wants to root it. now i could just go thru the long process to root on 2.2.1 but i would rather downgrade (if i can) to 2.2 and use z4root. how could i tell (if i even can) if it came stock with 2.2 or 2.2.1? stock 2.2.1 as i understand it cannot be downgraded but a phone that came with 2.2 and then updated can, am i correct?
