iPad 3 (A1430) activation fails after restore
I have an iPad 3rd Generation Wi-Fi + Cellular (Model A1430).
The iPad was stuck on the activation screen with the message:
"Activation could not be completed. Please restore the iPad and install the latest version of iPadOS and attempt activation again."
What I have already tried:
- Connected the iPad to a Mac.
- Restored the iPad completely using Finder in Recovery Mode.
- Installed the latest supported iOS version successfully.
- Connected to a working Wi-Fi network.
- Tried activation multiple times.
- Apple Check Coverage recognizes the device correctly and shows it as a valid iPad 3 (A1430).
- Finder and macOS detect the iPad normally over USB.
The restore completes successfully with no errors, but activation still fails with the same message.
Has anyone seen this on an iPad 3 A1430 before? Could this indicate a baseband/cellular hardware failure, or is there another way to diagnose the activation issue?
Any help would be appreciated.
