Hi..need some help with bt and wifi address not available in my ptm z mini. Even after using SN to write a new address and was confirmed successful but when i switch on the phone, it still shows unavailable.. have not been able to use the bluetooth or wifi, anytime i try to start any of them, it will not come on. The wifi will keep loading trying to on but at the end of the day, the phone will freeze/hang until i restart the phone.. I also can not load or enter the phone's recovery mode, instead it will show the techno logo and freeze there
