HTC Desire U hard reset

Before you buy a new cell phone or new tablet, please try the following procedure to repair your device. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card. It is impossible to recover your data after doing a hard reset, so online backup is always important. For all of your data, a backup should be done on an external device, hard drive, raid system or media.

reset by using the hardware buttons on HTC Desire U.

You can return your phone to its original state, as it was when it left the factory. This is also called a hard reset. You might want to do this if you are giving your phone to a friend or relative and you want to remove all your data first, or if your phone has a persistent problem
that is not solved by powering off the phone and then powering it on again.
A factory reset will permanently erase all your personal data and customized settings, and also removes any programs you have installed. Make sure that you have backed up the information and files you want to keep.
If your phone hangs or freezes, we recommend that you do a “soft” reset instead of a hard/factory reset. To perform a soft reset, remove the battery, wait for a few seconds, and then re-install it. After re-installing the battery, turn on the phone.
