Open recordApple error codes: restore, update and sign-in errors
Apple's numbered errors mostly appear when an iPhone or iPad is being restored or updated from a computer, and when you sign in to an account or a store. A restore error shown in Finder or iTunes names a number such as a four-digit code, and the number usually points to one of three things: the computer's connection to the device, the computer's security software, or the device's storage and hardware. The first step is the same for all of them: use the original or a certified cable, plug it directly into the computer and not into a hub, and restart both the computer and the device.
Update the computer's software first, since an old Finder or iTunes is a common cause of failure, and check that the date and time on the computer are correct. Security software and a VPN can interrupt the connection to Apple's servers during a restore, so switch them off while you restore. Free space matters too: an update needs room to unpack, and a device with little storage may fail partway through.
For sign-in and store errors, check that the Apple Account is in good standing, that the device's date and time are right and that Apple's system status page shows the services as available. Errors that name a payment method are cured by updating the method or by clearing a balance, and errors that name a device are cured by signing out and in again. If the same error returns after a restore in recovery mode, the cause may be hardware, and an Apple Store or authorized provider can run diagnostics.
Our iPhone and iPad page covers the restore and update errors we handle in detail. Before a restore, back up the device if you can, because a full restore erases it, and keep the device's serial number ready for Apple.
