I agree it would be crazy. I've been a long time android user and sometimes you have to do crazy things to accomplish what you want...So I am glad to hear. But to make sure i understand. Install id7 Recovery and then we are good to update (if we want to) and AIO will continue to work on .502 through USB?It would be crazy to expect anyone to do the second thing you are suggesting. Plus after updating to 502 downgrading is not possible.
and yes install id7_recovery before updating or you will get locked out.
