Hello, I have a Samsung Galaxy S2 sph-d710 for Boost Mobile. A few weeks ago I attempted to put an international rom onto it, and it softbricked my device. I took it to someone to get it fixed and he seemed very "seedy"... I was wondering if it's possible for him to put codes in there to make the phone destruct, or for him to read any text messages, or anything to do with spying. Thanks!
