The cause of the kernel panic is SMC BSC failure with sensor array 0-7 is 0, 3145728, 0, 0, 0, 0, 0.

I was checking the iFixit page with the different hex codes but it has not been updated for the 16 Pro Max. I saw somewhere that the issue is the charging port flex, could anyone confirm? By the way I will check how much damage there is inside before ordering a new charging port flex.

I reset Bluetooth and checked connections, but the phone still shows it’s “talking to someone” or stays connected to something I can’t see. It started around 2–3 days ago after a weird disconnection event.

Could this be a rogue Bluetooth pairing, AirPlay hijack, or something more serious? I’ve already tried:

– Resetting network settings

– Turning Bluetooth off/on

– Hard reset

– Forgetting all devices

Any advice? I’m worried something might be hijacking my audio.

Symptoms:

- The button still makes a "click" sound when pressed, so it's not physically jammed.

- The Volume Down button works perfectly and shows the volume bar on the screen.

- The Volume Up button does not show the volume bar or respond at all.

- I have already tried a force restart and checked the settings, but the issue persists.

Could this be a loose connector on the logic board caused by the drop, or is it more likely that the internal flex cable needs to be replaced? Since this is a newer model, are there any specific things I should watch out for before opening it?

I'm trying to identify the component behind a recurring SMC panic on an iPhone 16 Pro Max (iPhone17,2).

• iPhone 16 Pro Max (iPhone17,2)
• Current iOS version installed
• Device had a liquid exposure / water damage incident approximately 3 months ago

• Phone boots normally
• All functions appear to work correctly
• Cellular, WiFi, Bluetooth, cameras, Face ID, charging, speakers and microphones appear functional
• No noticeable overheating
• No performance issues
• Device consistently reboots after approximately 2 minutes 50 seconds of uptime (~180 seconds)

I have collected multiple panic-full logs from different reboots.

All logs show the same panic:

SMC PANIC - ASSERT
SMC BSC failure, TAOC

Additional entries:

Misc(2) OUTBOX1 not ready

Sensor data:

S.sensor array 0 - 7 is:
0, 2097152, 0, 0, 0, 0, 0

F.sensor array 0 - 1 is:
0

The value is always:

2097152

which equals:

0x200000

• Opened device and visually inspected logic board and connectors
• No visible corrosion found
• No green residue
• No obvious liquid damage remains
• Cleaned accessible connectors with IPA (isopropyl alcohol)
• Reassembled device successfully
• Issue remains unchanged

Does anyone know what TAOC maps to on the iPhone 16 Pro Max / iPhone17,2?

Is TAOC:

• a temperature sensor?
• part of the USB-C / charging port assembly?
• a sensor on the lower daughterboard?
• a logic board sensor?
• another SMC-monitored peripheral?

Before moving to board-level repair I am considering replacing the complete lower USB-C / charging port assembly because of the previous liquid exposure.

Any information regarding TAOC, sensor array bit 0x200000, or similar cases would be greatly appreciated.

Thanks!

Details:

• Storage is completely full (0 bytes free)
• No iCloud backup and no computer backup at all
• All photos, videos, WhatsApp chats, contacts… are extremely important – data loss is NOT an option

What I already tried:

• 3uTools → fails with error -100 at ~71% (filesystem writing blocked by full storage)
• Recovery mode & DFU mode → same result

I need a way to fix this while keeping 100% of the data (Retain User Data / no erase). I’m okay going to a trusted technician in Cairo if needed.

Any working method or recommendation for a reliable repair shop in Egypt that can solve this without wiping the phone?

Thank you so much for any help!

Here are the details:

• The phone sometimes powers on, shows the Apple logo, and then immediately restarts.
• I have checked that all connectors (battery, display, Face ID, MagSafe) are seated properly.
• The device does not stay stable even without the back glass connected in some tests.
• Attempting a DFU restore does not work; the phone either restarts during the process or gives errors.
• All screws were double-checked, and no obvious damage is visible on the board.

Has anyone experienced a similar issue after a back glass replacement on the iPhone 16 series? Any guidance on diagnosing or fixing this problem would be greatly appreciated.
