Thank you for accepting my request, I have brought my son a 2nd hand iPhone 5c on O2 as I know this takes giffgaff sims.. The owner of the phone said she didn't know the apple id password (but my son has apple id anyway) nor knew the iTunes password, I know the phone isn't stolen.

Well the phone wasn't taking the sim card so I've been on Google and done the hard reset thing and it only ever gets just over halfway through then stops saying error 50 and now my phone won't move on from this.. I have been trying for 6 solid hours now.. I can not tell you how many times I have tried... Can anyone help pleaseeeeee
