Mlais recently release their Android 5.0 Lollipop upgrade and for those not familiar, you can find the step by step tutorial below. Just remember to do all this with caution and note that the procedure will probably brick your phone if done incorrectly.
The Mlais M52 is the phone manufacturer’s recently released budget phone that has a striking resemblance with Xiaomi Red Note. Also remember that the ROM is tested only on the specific phone and will probably not work with other phones with similar specifications. The procedure is done via Cable Flash method.
What you need:
- Download the ROM and Flash Tool here
- PC (make sure to run as admin to avoid errors)
- Mlais M52
- Charge battery at least 70% or higher
- Micro USB data Cable
- Patience (the procedure is quite long but detailed enough)
