ECID Not Registered Install: A Comprehensive Guide to Troubleshooting and Solutions

• registered → enable features and show success.
• pending → poll GET /devices/device_id/status with backoff, or show "Registration pending" with estimated wait.
• failed → show actionable error (e.g., "ECID already registered", "Attestation failed", "Network error") and allow retry or manual.

• If you never saved blobs for the unsigned version you’re targeting, you cannot bypass this error. Apple will not issue new signatures for old firmware.
• The error essentially confirms your ECID is not “registered” (i.e., no valid signature exists) for that install operation.

Webview/Mobile Fix:

Use the AEP Edge Identity extension to pass the native app's ECID to the webview [Source 0.5.6].

1. Put your iPhone into DFU mode (Screen black).
2. Download Zadig (open-source USB driver utility).
3. Open Zadig. Go to Options > List All Devices.
4. Select your device (look for "Apple Mobile Device (DFU mode)").
5. In the target driver box, select libusb-win32 or libusbK.
6. Click "Replace Driver".
7. Rerun your restore tool. The error should vanish.
