Release buttons when the ZTE logo or Android Robot appears.
Navigate to Recovery Mode using volume keys and select using the Power button.
If presented with "No Command," press and hold the Power button, then press Volume Up once, and release both.
In the Android Recovery menu, select Wipe data/factory reset.
Select Yes to confirm.
Once the process is complete, select Reboot system now.
