Sony Xperia C3 problem with changing wallpaper

[Brittany]

Hi, please help. My friend reformat my phone. This sony Xperia c3. After that, he reinstalled some of the internal apps of this phone and I don't know why are they. He reinstalled it to reduce the internal space to keep from the storage for being full. Now here's the case, when I was about to change my wall paper and was about to input photos on mu contacts from my album, the dialog box states that "unfortunately, processing com.sonyericsson.com has stopped" And I cannot edit the photos. Please help thanks a lot.

Try performing a system repair using PC Companion as this will often fix issues - This will factory reset your phone and erase all data so best to backup before you begin

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP
