またVerも最新のものにしています。

メモ帳で線を何本か描いてみたのですが綺麗に縦に色が塗れなくなっていました。

普段お風呂に入る際に浴室にiPhoneを持ち込んでいるため、原因として考えられるのは水没かと思うのですが、こちら復旧させるにはどうすればよいでしょうか。

iPhone 12のスクリーンを交換しています。

スピーカーとセンサーアセンブリを移植し、本体に接着する前に動作確認を行いました。この時点では正常に動作していたのですが、いざ本体と接着するとタッチが反応しなくなってしまいます。どのような原因が考えられるでしょうか？

  • 再度本体からスクリーンを取り外し再起動して、浮かせた状態では正常に動作します。
  • また、別な交換用スクリーンを試してみましたが同様の状態になってしまいます。
  • 本来ついていた純正のスクリーンに戻した場合は問題なく動作します。

1週間後、熱くなることはなくなりましたが、時折スクリーン上に緑色の縦線が入るようになりました。再び電源を切り、半月後、この問題はなくなりました。

携帯電話のすべての機能が使えるようになりましたが、FaceIDは使えません。Appleストアに持っていったところ、カメラユニットを一度外して再装着するだけでいいと言われました。しかし、水濡れの痕跡があるため、Appleストアで修理はしてもらえません。

Face IDの障害を回復できる簡単な作業や、それに関するアドバイスをお待ちしています！Face ID機能があるからこそ、このiPhone Xを大切にしています。

My iPhone 5 (model A1429) will not boot into iOS.

When the power cable is connected, the iPhone boots up initially and displays the apple logo for ~3.5 seconds. Then it goes to a blank screen for another ~2 seconds and the process repeats (indefinitely it seems - at least at this point).

When the power cable is removed, the screen instantly goes blank again. Nothing happens if I press the power button when the iPhone is not connected.

I can get the iPhone into recovery mode by holding the home button before I plug it in, and then it stays on the recovery screen, not coming on and off like the apple logo was earlier. Again, when I unplug the cable it goes back to a powerless blank screen.

The iPhone is detected on iTunes in recovery mode and I have attempted to restore it, using both my MacBook and a Windows PC. Each time, it results in an error at the point when the iPhone appears to restart. I see Error 2001 on the MacBook and Error 21 on the windows PC.

I've updated to the latest iTunes version, restarted the computer several times, and tried different USB ports.

I was also able to get the iPhone into DFU mode, where the screen was blank—but it was recognized in iTunes as being in recovery mode. Just as before, the device will not restore, and I get various error codes across my Mac and PC.

I have since opened the device up and confirmed that the battery is securely attached to the logic board.

It is also worth mentioning that my iPhone is no longer under warranty.

At this point. my assumption is that the battery itself is dead, and won't hold any charge, which is why the device shuts off immediately after removing the power cable. Does this seem reasonable and should I order a new battery? Any other suggestions?

Many thanks,

Bradley

Now, I'm having a few problems with it. I will explain the problems one by one, after doing all the diagnosis I can on my end:

  • When I charge my iPhone, it shows the battery percentage indicator, but the battery percentage doesn't increase.
  • The charge indicator will stick on the number that's currently on the display.
  • After restarting the phone, I see the battery percentage increase—but this doesn't work every time.
  • Sometimes the phone charges properly, but I have to face this issue most of the time.
  • When I do a hard reset (home+power button), the battery percentage drops from around 25% to only 8%.
  • When I try to connect my phone to my PC, the phone restarts again and again.
  • Sometimes, when I use my phone while charging, the battery percentage will not increase.
  • When I charge my phone with the battery below 10%, the phone restarts again and again.
  • Sometimes, when the battery is totally dead and I try to charge it, the phone won't start, and it will only show the red indicator on the screen.
  • I've been facing this issue for the past week. My phone is currently on iOS 7.1.1.
  • When the phone gets to 100% charge, it does not show the full charge indicator on the battery.
  • I need to unplug and connect a few times to make the iPhone connect to iTunes, but iTunes works fine on the phone.
  • The phone has never been repaired before.
  • I've tried changing the charger and cables. I've also recalibrated the battery and performed a restore, but that didn't fix the problem.

Is this issue due to a bad battery, or is there some problem with the phone's logic board?
