しばらくは快適でとても気に入っていましたがある時から全く持って外側画面がつかなくなりました。閉じても中がずっとついている状態で通知などが来ても閉じてる状態なのに中の画面が光っていました。

落下や水没などはしておらずまた fold switcherなどを利用して無理やりサブディスプレイを起動させようとすると電源が落ちてしまいます。

adbにて一通りのログを取ってみたのですがどうやらサブディスプレイそのものを物理的に読み込んでいませんでした。また通常なら開け閉めを読み取って角度を出す部分もうまく表示されていません。そこで一度中を開けて差し直してみたりしたのですが症状は変わらずです....

このような場合サブディスプレイをフレックスケーブルごと交換したら治りますか？それとも内部のフレキシブルケーブルの断線によるものでしょうか？一応サブディスプレイ側のバッテリーは読み取っているのでヒンジにあるフレキシブルケーブルの断線等は無いのかなと思っています。

どなたか詳しい方お助けお願いします。

This means that, sporadically, it will register as being constantly held down.

Beyond being irritating when trying to listen to something and the volume bar appearing constantly on the screen, it is more functionally serious.

Whenever I reboot my phone, or it runs out of power, it will boot into the recovery menu and endlessly scroll through the options. I have to get lucky and wait for a period where the button is not registered as held and attempt to boot the phone. This can take many attempts (half an hour this morning) and I worry will eventually become impossible.

My question: can the volume button be repaired at home? Various sources online suggest that one cannot reach the volume button, even with a full tear down. I am unwilling to power off the system to check given the above.

SoC: A15 Bionic (8110 Rev 11)

iOS Version: 17.4.1 (21E236) / Darwin Kernel 23.4.0

Symptom: Device automatically restarts every 3 minutes in a continuous reboot loop.

Hi iFixit community,

I am troubleshooting an iPhone 14 Plus that triggers a panic-full reboot every 180 seconds. Below is the raw header and panic log extracted from the device:

}

Technical Analysis:

• Hardware Identification: Model identifier iPhone14,8 and target d28 both confirm this is an iPhone 14 Plus.
• Sensor Array Error Code: S.sensor array explicitly flags value 0x500000 (which corresponds to 5242880 in decimal).
• Bus Failure: On the iPhone 14 Plus architecture, 0x500000 is the combined bitmask representing the Dock Flex / Charging Port thermal sensor array (0x100000) combined with the Wireless Charging / Back Glass sensor line (0x400000).
• SMC Assert: The System Management Controller fails communication over the BSC (Bus Status Controller) due to missing SMBus/I2C thermal readings from TAOP/TAOJ.

Local shops suggested a battery replacement, but the panic log contains no battery gauge failures (TG0B, TG0V, or Gas Gauge).

Questions for the community:

1. Has anyone resolved this exact 0x500000 / SMC BSC failure on an iPhone 14 Plus strictly by replacing the Dock Charging Port Flex Cable with an OEM pulled part?
2. Does a missing/damaged Wireless Charging Coil flex connector trigger this entire 0x500000 bitmask on its own, or is the Dock Flex always the primary culprit?
3. If a new OEM Dock Flex does not resolve the panic, which diode readings / filter components near connector J6400 should be checked?

Thank you!

my co-worker checked his phone yesterday morning when it was still plugged in, the phone was in recovery mode. When at work, he handed me the phone and i tried booting it, it began boot looping.

Did the standard force restart, it boot loops until it goes into recovery mode

I took it back home and attempted to update the iPhone to the latest iOS Version using my MacBook Air with no luck after several attempts with the error code 4013 showing up (I even updated the macOS Software to the latest version to see if that help out but same results).

I changed cables, did the same procedure again but on my Windows 11 PC using Apple Devices, still no change.

I used 3utools and checked the logs, i included the photo to show

I am starting to believe this is stemming from an hardware issue, the best thing would be opening up the phone and checking which component is causing this issue. Is my work accurate?

I tried JCI Drawings; but it has nothing for the Samsung SM-G975U Mobile Phone.

I also tried DZKJ, W2R and ZXW Software but none of them have schematics or real Board view for SM-G975U.

As I'm sure many know, the SM-G975F board and design is completely different compared to the SM-G975F.

I need REAL SCHEMATICS with part numbers and values of components for Samsung SM-G975U.

I have board view of the SM-G975U but it has no real part numbers.

I need to be able to look up parts on Board view and find the part on the schematics.

Please let me if anyone has these or know how I can get the real FULL SCHEMATICS and BOARD VIEW that have part numbers (NOT JUST A PART LAYOUT with non-standard Part numbers).

Please let me know ASAP.

Best Regards,
-James
