Performing a factory reset (hard reset)

If you’re passing your phone on to someone else or your phone has a 

persistent problem that cannot be solved, you can do a factory reset 

(also called a hard reset). This returns your phone to the state it was in 

before the first time you turned it on.

Factory reset will not erase the data and files that are on the storage card.

Factory reset is not a step to be taken lightly. It’ll permanently 

delete all your data and customized settings, and will remove any 

applications you’ve downloaded and installed. Be sure to back up any 

data and files you want to keep before you do a factory reset.

Performing a factory reset via settings

Press HOME   > MENU, and then tap 

Settings.

Tap 

SD & phone storage > Factory data reset.

On the Factory data reset screen, tap

 Reset phone, and then tap 

Erase everything.

Performing a factory reset using phone buttons

If you can’t turn on your phone or access the phone settings, you can 

still perform a factory reset by using the buttons on the phone.

With the phone turned off, press and hold the VOLUME DOWN 

button, and then press-hold the POWER button. 
Wait for the screen with the three Android images to appear, and 

then release the VOLUME DOWN button.
Press VOLUME DOWN to select 

FACTORY RESET, and then 

press the POWER button.
