I have a tecno R7 phone that recently began malfunctioning. It initially started with the WiFi and hotspot not coming on(Mac address unavailable but the address is visible when i boot into safe mode) then later it began hanging and sometimes failing to boot properly. It loopboots the tecno and sometimes it just automatically restart after booting to the home screen. I resorted to factory reset and wiping the cache. The problem still persisted. I noticed that anytime I restore userdata, the phone boots normally and works for about 3mins before freezing. I xonsidered flashing the phone. It's mt6589 based phone but following my taking the phone to tecno fo the screen to be replaced. I've noticed the phone always writing"upgrading android" for about 2wks before it stopped writing that. I downloaded the backup ROM from this site but the scatter reads mt6592. I've tried using it to flash the phone but I get "pmt has changed, it must be downloaded". I later booted into safe mode(using power and vol down button) and ran an automatic testing. The WiFi worked and when I went to the "about" option, it showed "bb chipset" to be mt6591" not 6589 or 6592. Please, how do I fix this? Thanks.
