Hi, The error 47 is a problem with the baseband or IMEI. This can occur because of jailbreak and sim unlock. If you don't jailbreak your phone, it can come from the baseband chipset. Check that IMEI corresponds to that of the box of your phone. For the baseband it must be 6.02.00 for an iPhone 5s iOS 9.3.4.
