iPhone 14 Pro Max — sensor array 0xa0000: Logic board sandwich
Low confidenceVerified sourceSMC: silent sensor
On the iPhone 14 Pro Max, 0xa0000 means: Logic board sandwich (gyroscope) + front sensors flex.
What does this code mean?
SMC “BSC failure” panic: the system management controller (built into the SoC) periodically waits for a response from each mandatory sensor; here, two faults add up: board gyroscope (0x20000) and proximity (0x80000). With no response, it forces a restart, which repeats roughly every 3 minutes (≈180 s) as long as the sensor stays silent.
Which part to test first?
Test the front sensors flex first (known-good part), then check the interposer and the gyroscope pads.
