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 before factory reset. 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. With or without insurance, if your cell phone lost, damaged or stolen at least your invaluable data is backed up in a safe place. If you are about to sell your phone and you want to wipe your personal data, or if your phone affected with virus you have to do a hard reset. In some cases, you can delete the forgotten password or lock pattern from your device as well. All information is for devices with stock based ROMs. If you are using rooted device, always back up your EFS folder first, containing your IMEI info, etc.!

    1. With your thumb or finger, open the back cover by lifting up from the left side of the cover.

    2. The RESET button is located at the bottom left below the battery compartment and SIM card slot. Use a small object with an unsharp, pointed tip such as a toothpick to press the RESET button.

    If a normal reset does not solve a system problem, you can perform a factory reset. After a factory reset, the phone is restored to its default settings—the way it was when you first purchased it and turned it on. You will lose any programs you installed, data you entered, and settings you customized on your phone, and only Windows Mobile software and other pre-installed programs will remain.

    There are two ways to do a factory reset. One way is perform a clear storage process through the phone settings. The other way is to perform a hard reset by pressing certain buttons on your phone, in cases when you are unable to start up your phone and enter the phone settings.

    Warning! Your phone will be set back to factory default settings. Make sure that any additional installed programs and important data on your phone have been backed up before you perform a factory reset.

    Important If Encrypt files when placed on a storage card is enabled, back up all files from the storage card before performing a factory reset (Clear Storage or hard reset) or updating the operating system. Otherwise, you will no longer be able to access the encrypted files on the storage card. Use ActiveSync or Windows Mobile Device Center to transfer files between your storage card and computer. After the procedure, copy your files back to the storage card.
