How to Do a Master Reset on a Cell Phone
Sometimes you can reset your cell phone to resolve some common issues you may experience, including inability to email, text or connect to the Internet. A reset may also help improve call quality issues, such as garbled sound or dropped calls. During a master reset, all data on the phone is erased, and the cell phone is restored to its original factory condition. The steps to accomplish a master reset on a cell phone will vary slightly by model.
Tap or press the "Menu" or "Start" key on your cell phone.
Tap or click "Settings" and scroll down to "Security."
Tap or click "Delete/Reset." Depending on the model of your phone, you may need to choose "Reset Phone."
Click "Reset Phone" or "Erase All Data." Enter your phone's security code. By default, the security code for most cell phones is either the last four digits of your cell number or the last four digits of the account holder's Social Security number.
Confirm that you want to reset the phone by clicking "OK." Wait for the phone to power off and on.
