I recently bought a Galaxy S2 that was flashed with cricket. I love cricket so far but my phone is a sprint phone and it keeps telling me to install the updates. I was told at the store that I bought it from to never touch the updates or it will mess up the phone. Well my kids play on the phone all the time and I am afraid they are going to push the install button on accident. If I wanted to sell my phone as a sprint phone could I do a factory reset on it so I can purchase a real cricket phone? If not what can I do to make it stop saying the install now? Thanks everyone.
