I bought from the hands of BB9700. Initially, the handset was sewn under the MTS. As I understood the seller before selling it unlocked it through Multiloader. Is it possible to roll back all these actions? Get a locked phone under the MTS? And then enter the MEP code to unlock? Because Now when you enter the MEP2 command, the device does not react at all. I would be grateful for the help.
This model is only broken by code, insert another SIM card, check it is unlocked or not
