Hello guys, please help me with TECNO M3 STOCK backup. My phone was popping error into settings several times. So I decided to flash it with another TECNO M3 file without knowing it won't be compatible with mine. My TECNO m3 was having blue background in the app drawer. The one I flashed it with is having black background. And it is not working. The phone end up in TECNO logo. Help me with the early stock backup that having blue background in the app drawer.
