Hi. Thanks for using www.bosstech.co.za I’ll be giving you reset instructions below. Remember, hard resetting your phone will delete all the data on your phone.
Switch off your phone
Press and hold power button and volume down. This will take you to the factory mode.
Use volume down button to scroll down to “clear emmc” and use power button to select.
Your phone will format all data and restart.
These are tested instructions and proven to work on this device, use the comment button below to request for further assistance on the same topic or use the ask box on top to ask a new question.
