Restoring Factory Data
If you reset your phone to the settings that were configured at the factory, all of your
personal data stored on the phone, including information about your Google Account,
any other accounts, your system and application settings, and any applications you
have downloaded will be erased. Resetting the phone does not erase any system
software updates you have downloaded or any files on your microSD card, such as
music clips or photos.

1. On the Settings screen, touch Privacy > Factory data reset.
2. When prompted, touch Reset phone, and then touch Erase everything. The mobile phone resets the settings to the original factory settings, and then restarts.

Unlocking Your Huawei U8652 Huawei Fusion phone if you forget the lock pattern
If you have already created a Google account, you can unlock your mobile phone by
the following methods.
• After you have entered the wrong sequence five times, a Forgot pattern? button
will appear. Touch this button to enter the Google account interface. After you have
entered your Google account password, you will be able to reset the unlock pattern.

• After you have entered the wrong pattern twenty times, you will be taken directly to
the Google account interface. After you have entered your Google account
password, you will be able to reset the unlock pattern.

Backing Up your Data

You can use your Google account to back up your mobile phone’s settings to Google
servers. If you replace your mobile phone, the settings you have backed up will be
transferred to the new mobile phone the first time you sign in to your Google account.
1. On the Settings screen, touch Privacy.
2. Select the Back up my data check box.

General advice: Before you buy a new cell phone or new tablet, please try the following procedure to repair your device in a software way. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card before doing 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.! Please also note, that a hard reset operation will not unlock your mobile phone's SIM lock or network lock, but it will remove the unlock pattern, remove the user password or PIN password (NOT the SIM card's 4 digit PIN code). Also note that the firmware version will not be affected in any way, it will not be downgraded, it will remain the same you are using and if you have rooted your device, root privileges remain also unaffected.
