Factory Reset for locked Xperia J


I have an Xperia J but haven't used it in about 2 years and I now need it as a back up phone, however, I have forgotten the PIN code I used to lock it and there seems to be no way of getting into it. I have tried downloading Sony PC Companion but that is no help as my phone isn't listed and it won't connect anyways. I have tried numerous "hard factory reset from locked screen" using the buttons on the side but nothing works. 

Please could you tell me how I would unlock it or if I would have to take it to a shop?

Re: Factory Reset for locked Xperia J

If the above does not work then you need to follow this guide which is probably the better option if you want your phone back to factory settings


Performing a system repair using PC Companion - This will factory reset your phone and erase all data

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
