Pheone gurus please help on this one, I just bought this Q10 from my friend, then I wipe the phone and when the phone was completely wipe and start again, then the problem comes, it keep ask for BlackBerry Anti-Theft email and password and I took it back to the guy and the guy doesn't remember the email he actually use(he get like 6-10 emails and he doesn't remember the one he use), I've taken it to engineers and whenever they upgrade the phone it will still ask for the anti-theft... except I downgrade the phone instead of upgrade and the current version on the phone doesn't support some features (Apk apps keep closing anytime it's loaded) including Amazon app store.. Please Any idea on how to remove dis anti-theft and upgrade this phone....

Well, ask the seller to unlock it. it's his part to play. Else you return the phone
