iPhone panic 0x51, 0xc4, 0xb1: Touch ID / Face ID / Secure Enclave
Panic codes: 0x51, 0xc4, 0xb1, 0xc00000
How to fix it
The panic points to the security parts: Touch ID, Face ID or the Secure Enclave.
1. Check the Touch ID / Face ID flex and connector.
2. If the flexes are good, the problem is on the board (Secure Enclave / CPU area).
