Error 1110 appears during an iTunes or Finder restore when the iPhone cannot complete writes to its NAND flash storage. Apple does not publicly document this error code, but repair community experience consistently associates it with storage exhaustion. The goal is to extract your data before any restore attempt erases it.

The Cause: Full Storage Bootloop

iOS writes temporary files, caches, and system logs to NAND during every boot cycle. When storage is at capacity, those writes fail. The boot sequence aborts, the phone restarts, and the cycle repeats until the device drops into recovery mode.

A standard iTunes restore will fix the bootloop by erasing the NAND and reinstalling iOS, but that wipe destroys all user data. If your photos, messages, and contacts have not been extracted first, they are gone permanently.

Recovery Path for Full Storage

  1. Clear system caches: We use specialized software and hardware utility tools that interact with the device's native update process to safely clear system caches and temporary files. This frees up just enough space for the operating system to complete its boot sequence without erasing your photos or messages.
  2. Boot natively: Because this is a logical filesystem error, no soldering or board-level repair is required. The phone boots on its own hardware once sufficient space is available.
  3. Extract your files: Once the phone successfully boots natively, we enter your passcode and safely extract your files.

Why Generic Software Cannot Help

Tools like Dr.Fone, UltData, and PhoneRescue require the phone to boot and connect via USB. An iPhone stuck on Error 1110 cannot establish that connection, so these tools have nothing to communicate with.

A standard iTunes restore will erase the NAND to install a fresh copy of iOS. If your data has not been extracted first, it is permanently lost. Standard software tools cannot bypass this.

Do not attempt an iTunes restore. A restore erases the NAND to install a fresh copy of iOS. If your data has not been extracted first, it is permanently lost. iPhone storage is encrypted by the Secure Enclave and cannot be recovered after a wipe.

Frequently Asked Questions

What is iPhone Error 1110?
Error 1110 appears during an iTunes or Finder restore when the device cannot complete writes to NAND storage. This can happen because the storage is completely full and iOS has no space for system files. The restore fails partway through and the phone remains unbootable.
Why does a full iPhone cause a bootloop?
iOS writes temporary files, caches, and system logs to NAND during every boot cycle. When storage is at capacity, those writes fail, the boot sequence aborts, and the phone restarts into the same failure. The phone will eventually present a Connect to iTunes screen or enter recovery mode, but a standard restore will erase all user data to free space.
Can I fix Error 1110 with software?
An iTunes 'Restore' will fix the bootloop, but it permanently erases all your data in the process. If your goal is data recovery, specialized tools must be used to clear space and update the device without formatting the NAND.
Is my data still on the phone?
In most cases, yes. The phone cannot boot, but the NAND flash still holds your photos, messages, and contacts. iPhone storage is encrypted with keys tied to the device's Secure Enclave, so the data can only be accessed by booting the phone on its own hardware and entering the passcode. We use specialized tools to free up enough space for the phone to boot normally, then copy your data.
