A Finish Repair entry can mean the installed part still needs Apple's calibration workflow. It is not a carrier-unlock request. First separate an unfinished software-assisted repair from an incorrectly installed or ownership-protected part; those problems need different help.
Understand what the message establishes
Apple's Repair Assistant installs calibration data after supported repairs. The affected model and component determine whether the workflow is available. A message alone does not prove that a replacement is counterfeit, and successful calibration is not a physical inspection of every connector or seal.
Keep the repair receipt and the exact on-screen wording. If a shop installed the part, its responsibility for completing the work is more relevant than an unrelated phone-unlocking service.
Work through supported prerequisites
- Find the exact iPhone model and which component was replaced. Compare that combination with Apple's current Repair Assistant table. Do not assume a supported display means every other component is supported too.
- Use a trusted ordinary Wi-Fi connection. Apple excludes captive networks and networks requiring 802.1X authentication from this workflow; a working hotel login is therefore not the same test as a suitable home connection.
- Check Apple's power and software prerequisites: more than 20 percent battery and the latest supported iOS version. Follow safe update preparation and preserve important data before changing software.
- Open Settings, General, About, then Parts & Service History. Where offered, choose Restart & Finish Repair and follow the displayed instructions. Avoid instructions copied from a different model or operating system.
- Recheck the entry after completion and test the repaired function. If the process still fails, give the installer the model, part, exact error and prerequisite checks already completed.
Ownership and hardware limits
Apple warns that an installed part can be protected by Activation Lock and directs customers back to the service provider when appropriate. No public code generator, carrier unlock or screen-passcode change supplies the missing authorization. Do not pay someone promising to bypass it.
Escalation
Stop if the phone is damaged, unusually hot or behaves unsafely. Do not reopen it merely to clear the message. Ask Apple or the repair provider to distinguish calibration, installation and part-ownership issues. This guide does not offer internal repair instructions, guarantee biometric restoration or certify the quality of the replacement.
