Problem description
iPhone 14 fails to restore and throws Error 9 during iTunes / 3uTools restore. The restore process may begin normally but fails mid-way.
Upon inspecting the restore logs, communication failure is traced to the ROSE IC, confirming a hardware fault.
This issue requires board-level repair and cannot be resolved via software.
Symptoms
- Restore fails with Error 9
- Device stuck in Recovery or DFU mode
- Restore progresses partially, then fails
- Same behavior with:
- Different cables
- Different computers
- DFU restore
- Restore logs indicate ROSE communication failure
Solution
Diagnostic Steps
- Attempt restore via iTunes / 3uTools
- Confirm consistent Error 9
- Review restore logs
- Look for ROSE-related errors
- Rule out:
- Bad cable
- Faulty charging port
- Low battery voltage
- Confirm issue persists in DFU mode
Once logs confirm ROSE fault → proceed to board repair.

1. Prepare the Board
- Remove logic board from device
- Remove shields as necessary
- Protect sensitive components
2. Split the Sandwich Board
