Bootloop and random restart issues in android (Gionee A1 plus)
Did it suddenly started to do weird things? Can you specify the cause.
As per the mentioned details, you need to flash stock firmware from SPFlash Tool(as you have a MTK device). You can google for your firmware. And flash it while your phone is in download mode.
I too have faced many bootlops while flashing roms. So I flash stock firmware and all good.
