How To fix 0+ 8.31 too many pattern attempts

I recieved this unit here in our shop, 0+ 8.31 asking for a google account. You must know that this unit has no HARD RESET solution. The only solution is to wipe it via Android Multi-Tools free software.

Here is how:
1. Power on the phone and install first the drivers.
2. After installing the drivers, PRESS Volume DOWN and POWER ON at the same time, and insert USB cable. The unit must be in FASTBOOT MODE state. Take not that when drivers are not installed, the unit can't be in fas mode. So you must keep in mind.
3. If the unit is in fastboot mode,open the Android Multi-Tools, the software will detect the unit.
4. Type 8 and press ENTER. Wait for the unit to restart.
5. You are done!
