iPhone panic 0x20000: Sandwich board / Gyro not detected

Panic codes: 0x20000

How to fix it

The sandwich board may have separated, or the Gyro on the top board is not detected (iPhone 14 Pro Max restarts).

1. Check the Gyro U7300.

2. Check the pads for the Gyro U7300: 542, 543, 544, 545, 546, 6, 248.

3. A sandwich reball or a bottom board swap may be needed.

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