iPhone panic 0x300000: Proximity Flex / camera (0x300000)

Panic codes: 0x300000

How to fix it

The panic points to the Proximity Flex Cable or the camera (camera failure, autofocus, stabilisation).

1. Test with a known-good Proximity Flex.

2. Then test with a known-good rear camera.

3. Diode-mode the FPC connectors to find any fault.
