iPhone 14: iPhoneの基板（ロジックボード）修理を覚えるには、機材や練習方法などどうしたら良いですか？

Wed, 15 Jan 2025 08:23:50 -0700

iPhoneの基板（ロジックボード）修理を覚えたく、全く初めてになります。

パーツ交換などはすでに出来るのですが、今後は基板修理の世界に踏み込んで覚えたいです。

教えてくれる所がほぼなく、やむを得ず独学でと思っているのですが、必要な機材の購入や練習方法など、まずは入門として、何から始めたら良いでしょうか？

よろしくお願いします

iPhone 14: Why does my iPhone 14 has a smudge on the display?

Tue, 02 May 2023 08:26:28 -0700

My Iphone has a smudge which can be visible mostly on grey screens and also can be seen on screenshots. This is weird, since i can see it in a screenshot i think it has some thing to do with software but I'm not sure.

iPhone 14: How to remove broken back glass iPhone 14

Thu, 15 May 2025 21:13:56 -0700

Hello, I will be repairing a device in the next couple weeks. I am using a old broken one to practice on. For the life of me I cannot get this glass off. I have tried heating the back glass itwould not lift. I have tried with a mat and heat gun. I tried the combo of isopropyl alcohol too. Finally I purposely broken the back glass to mimic the phone I will be repairing. I'm just getting glass everywhere and tearing up the components

Nothing I do will get this glass off. Any tips would be great

I do have the front glass removed on my tester iPhone

iPhone 14: iPhone 14 restarting after a few minutes following screen replacement

Thu, 22 Aug 2024 02:58:06 -0700

I've been reparing iphones for a number of years, so this is by no means a 'noob' question.
I've just replaced a screen on an iphone 14 and the customer is now reporting that the phone keeps restarting every few minutes.
This is not a boot loop/stock Apple logo restarts, issue. The phone boots up as normal but after a few minutes use, simply restarts for no reason.

iPhone 14: Cable between battery and cam

Tue, 09 Apr 2024 18:33:56 -0700

Hi to all,

I bought a used iPhone 14 with already replaced battery. Sometimes it is charging correct and sometimes it paused because of hot battery. But it is not hot! Not even warm. I already ordered a new battery from here (but not delivered, yet).

I opened the iPhone to have a look and I found some scratches on the cable (or thin, tiny, black board) between battery and rear cam. It is connected beside the wireless charging cable.

I think it get those scratches from getting the old battery out of the phone.

Is here a temp sensor on this cable and make this strange problem? What is the name of this cable? Can I buy a replacement here or somewhere?

Regards

Patrick

Dear excellent engineers

After replacing the battery, nfc cannot be used even though the system has been updated.

I don't know if there is any line that will affect the normal operation of nfc.

iPhone 14: Why does my iPhone 14 keep rebooting after trying a repair?

Wed, 31 Jul 2024 10:24:49 -0700

I recently tried to repair my camera. Unfortunately, I damaged the flex cable that was attached to the back of the glass. I immediately stopped what I was doing, reconnected the battery, and camera cable, and put the phone back together without replacing anything. Now my phone reboots every so often when I am using it. Could this reboot be caused by the damaged flex cable?

iPhone 14: Does iPhone 14 work without the charging coil assembly connected?

Wed, 15 Apr 2026 09:17:35 -0700

I ask this because, after changing the back glass cover of this phone, upon reconnecting the charging coil connector and powering up the repaired phone, it crashes every 4-5 minutes without restart. I have to power it up manually, but the phone shuts down automatically. Before opening it, it worked flawlessly.

So the point here is what I screwed up?

This is what iDevice Panic Analyser says.

And it's likely right, but the phone shuts down also with the charging coil assembly disconnected, so I'm left wondering if the phone needs it to run -> I buy another functioning one

The phone has damage in the mainboard and a brand new charging coil does not matter at this point.

I fear the latter is the case, based on experience. Now I can panic like the phone does.

I got a second-hand iPhone14 online, the dealer said the backplate and the battery was replaced. NFC can be recognised by the phone ( Apple Pay pops up just fine), but nothing happens when paying. I’ve got no clue on the problem, and i can’t find any useful info online. Is there any way to fix it?

I dropped my iPhone 2 days ago, and the back completely shattered. I know that it will for sure need to be replaced. However, now my display isn't responding to touch at all, and I have 2 green lines and a purple line on my display (front is not cracked at all). I did a hard reset and it rebooted but still no luck.

iPhone 14: Won't boot correctly after screen repair

Sun, 07 Sep 2025 20:30:33 -0700

I have done a screen replacement on an iPhone 14 and now it will not boot past the apple logo or recovery mode.

When I reattach the old screen the phone boots completely normal (no touch hence the screen replacement) I have now tried 2 different replacement screens and have the same issue, I did manage to get it into recovery mode and do an update via iTunes, but this has not helped.

Any suggestions appreciated!
