I recently bought a Samsung Galaxy S II on eBay.
Found it to be running a custom Orange firmware
I flashed the firmware back to the standard stuff and now am up and running on the device.
I have since discovered that the CSC didn't update from ORA to XEU (which I believe any sim-free UK devices should be?)
I know the standard methods of changing the CSC involves a factory reset so my question is - what is the best app I can use to backup everything on the device so that I don't have to restore anything or what I do have to restore can be kept to the absolute minimum.
All of my contacts etc is on my Google account but I'm not sure what I need to backup to minimise what I need to manually restore.
Can anyone assist?
