iPhone 13 mini — sensor array 0xc00: Lower board
Low confidenceVerified sourceSMC: silent sensor
On the iPhone 13 mini, 0xc00 means: Lower board (gyroscope) + charging port 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 on the iPhone 13 mini: lower board gyroscope (0x400) and charging port (0x800). 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?
Fix the charging port first (known-good flex), then the lower board interposer/gyroscope.
