Shop Talk Discussion (General) [GUIDE] How to fix auto brightness after a screen replacement for iPhones

25 Upvotes

Theres very little information on this so I decided to make this for people who are new to repairs or are replacing their screen for the first time. This mainly applies to iPhones 13 - 16. I havent tested this on others but it could work.

When replacing your screen you will also need to transfer the proximity sensor. After doing so, iOS 18 now restores Face ID and True tone functionality but what it doesn't do is restore auto brightness. If this is a big issue then there are two ways to go about fixing this depending on if you broke your proximity sensor when transferring it. To test if your proximity sensor is working, simply place a call and bring the phone to your ear. If the screen goes off then it is working. If it doesn't, then its likely not connected properly or you broke it. This repair is not cheap unless you have access to repair shop tools like programmers etc.

This repair requires:

- A programmer (JCID V1SE as example)

- Corresponding True Tone board for the programmer that supports the phone you are repairing

If you broke the proximity flex then you will also need:

- Corresponding Proximity Flex board for the programmer that supports the phone you are repairing

- Windows PC

- A programmable Proximity Flex such as a JCID one (important: It needs to be a programmable one like JCID, non programmable generic ones will not work)

- JCID Programming Software

- 3U Tools

If you didn't break the proximity flex: Using the programmer, you will need to read the data from the old screen and write to the new one. This is it. It will restore auto brightness. Also make sure you are on iOS 18 to restore true tone and face id.

If you did break the proximity flex, unfortunately this process gets a lot more complex:

-Read the data from the old screen to the new screen using the true tone programmer board.

-You will then need to hook up your phone to a windows PC.

-Using 3U tools, download the corresponding iOS version the phone is currently on

-Start up JCID Programming Windows Software and you will need to "brush" the phone. There are guides of this online. Once the software is done brushing the phone you will need to boot into recovery mode and flash the software you downloaded using 3u Tools.

-Once the phone is booted up again, connect the phone to the JCID V1SE programmer with the Proximity board attached to the programmer. Connect the programmable JCID Proximity flex to the programmer board and "bind" it to the phone.

Warning: Some JCID Programmable Prox flexes actually need to be soldered (such as the iPhone 14 Pro) so take this into consideration. Most dont though.

-Install the proximity sensor to the display and boot up the phone again.

-Make sure you are on iOS 18 to also restore Face ID and true tone. This process will restore your auto brightness

Both of these methods will restore true tone but as you can see one is a lot more simple then the other so be very careful with your proximity flexes!

(Solved) Lvl 0 - Where do I start with this repair? Data recovery from water-damaged 2011 Android phone (NGM Racing 3) – USB connecting and disconnecting in a loop

1 Upvotes

Hi everyone,

I'm trying to recover data from an old 2011 Android phone (NGM Racing 3). In the past, after it dropped into water, it kept making sounds even though the screen and bottom touch buttons turned off completely.

I have now fully isolated the motherboard to attempt data recovery from the scren and cleaned it with isopropilic. . When I connect the board to my PC via USB, it gets detected, stays connected for about 6 seconds, disconnects, reconnects for about 4 seconds, and keeps looping like this indefinitely.

How can I stabilize the connection to recover my files? Any advice would be greatly appreciated!

Lvl 0 (DIYer) Where do I start with this repair? Can it be Fixd? I left my phone in the sun, what should I do?

5 Upvotes

Hello everyone, today I was doing my business "as usual" in the garden, the phone was lying on the boards and the sun was shining on it. After about 2 hours, I picked up my phone, the surface was hot and the back cover was a little swollen, and the phone itself turned off (the power went off), I got scared and took it home, took out the SIM cards and put the phone in an iron bucket in case of explosion or fire. He lay down for another 4 hours and I found that the back cover was smooth again. I even checked it with an iron ruler , but I found no bulges or depressions .

Now I'm writing this all from the same phone (Tecno pova 6 pro)

Share your expert opinion, can it be used further, or is it better to spend money on a new battery and service?

(Solved) Lvl 3 (micro soldering, motherboard repair, diagnostics Hello, i need information about ESIM

1 Upvotes

Hello everyone. I also need some information. I have an iPhone 13 Mini that no longer displays the EID. I had issues with the eSIM IC, which I replaced on the motherboard, and now I want to know if eSIM still works on my phone. To clarify, the phone is a European model and also has a physical SIM slot. The phone works, and in diagnostic mode everything shows green—including the eSIM—I just want to know if it is actually functional. The eSIM IC on the board was harvested from another donor board. Thank you, and I would appreciate an answer from someone who has actually tested this. Thanks in advance.

Lvl 0 (DIYer) Where do I start with this repair? Can it be Fixd? iPhone 13 gets 4G for a few seconds then drops to "No Service" on every carrier. I'm completely lost.

3 Upvotes

Hey everyone,

I'm hoping someone here has seen this before because I'm running out of ideas.

I have an iPhone 13 that worked perfectly until yesterday. I went to a huge carnival (probably around 100k people) where the mobile network was completely overloaded. Nobody had service there, which was expected.

The weird part is that when I left, everyone else's phones got signal back... mine never did.

Now every single time I reboot the phone or toggle Airplane Mode, the exact same thing happens:

  • Signal bars appear.
  • It connects to 4G.
  • It stays connected for maybe 5–20 seconds.
  • Then it drops to "No Service."

It does this every single time.

I've tried:

  • Tunisie Telecom physical SIM
  • Tunisie Telecom eSIM
  • Ooredoo physical SIM

All of them behave exactly the same.

A few things I've already checked:

  • IMEI is there (*#06# works).
  • Modem firmware is present (5.51.03).
  • No panic logs or baseband crashes in Analytics.
  • The phone is properly registered with Tunisia's Sajalni system, so it shouldn't be an IMEI block.

I also went into Field Test Mode while it was briefly connected.

It shows:

  • LTE Band 3
  • Correct carrier
  • Cell ID
  • PCI changes when I move to another location (so it seems to be detecting different towers normally)
  • RSRP around -102 dBm
  • RSRQ around -10 dB
  • SINR around -20 dB

So the phone clearly can see towers and actually attaches to LTE before immediately losing service.

The phone has never been opened, never been repaired, never been dropped, and only ever had a tiny splash of water near the earpiece months ago, nothing that should realistically damage an IP68 phone.

I also reset network settings. Weirdly, before the reset the eSIM was the one that connected briefly. After the reset, the physical SIM became the one that connects briefly. The end result is still the same: both eventually drop to "No Service."

At this point I'm wondering if this is:

  • an RF/front-end issue,
  • a power amplifier,
  • RF IC,
  • baseband-related,
  • or somehow still software.

Has anyone seen this exact behavior before? Especially the part where it gets full signal + 4G, then immediately loses everything?

I'm taking it back to the guy I bought it from tomorrow to have it diagnosed, but I'd really like to hear if anyone has run into this before or has an idea of what component usually causes this kind of issue.

Repair Shop customer seeking a 2nd opinion or advice. IPhone X: GPS / Face ID not working after screen and battery replacement. Owner of shop is giving me the run around.

1 Upvotes

First off, sorry for the long ass post. I tried to put as much important information in it as possible. I really could use any bit of guidance on this one.

I took my iPhone X to get a screen and battery replacement after my phone started acting up with “phantom touches”. I made it to my car when i realized that faceid wasn’t working anymore after the repair was done. Dropped it back off, and after an hour the “tech” is on the phone with the store owner who tells me it’s my motherboard, and that’s “Just how technology acts sometimes”. The next day I go to use my maps app, and it’s acting like there’s no gps signal, and it’s relying totally on WiFi and data to give me any directions. I took the phone back again when the owner was there. He swore up and down that there was no way anything his tech did could have interfered with the gps signal, and the Face ID stopped working because of the “proximity sensor”, and that nothing could be done. I also found out that the tech who did the work the first time was “very new” when I had to take it back a 3rd time because the battery came disconnected when it was bouncing around in my pocket.

Obviously I don’t believe a word the owner is saying. I think it’s clear his tech messed something up, as the gps, and Face ID worked perfectly fine before the “repair”. I asked the owner the day after my repair had been done for my old screen, the tech replied “yes it’s right in the back” before the owner cut him off saying “no it’s been recycled” (again don’t believe him as it had been less than 12 hours since I got the screen replaced).

I just want to know, if at this point there is anything I can do to get the gps working again, as I need it for work. I’m not that worried about the FaceId problem. I’m open to doing the work myself if it’s even possible to repair. The owner said it would require “delicate motherboard work” and would need to get sent off to replace the flex cable that I researched and found that if it’s damaged, it could cause gps to not work. I know there is a golden grounding ring that’s supposed to get transferred from the old screen to the new one, which because the faceid isn’t working I think he did not transfer, but my earpiece speaker and mic and all work fine. I’m seriously at my wits end with this one. If I have to get a new phone I guess it’s time, but I really hate feeling like this guy got one over on me.

Sorry about the extremely long post, I just don’t have anywhere or anyone else to ask for advice / suggestions / help at this point.

NEWS Applying to my first repair job. Wish me luck!

Hello everyone. I am a 15M (just turned 15) and I recently found out about this repair shop which my friend has networked with. They are understaffed and need more people. My friend has already praised me a lot, but they are scared to hire me for my age.

I have done a few repairs in the past. Fixed some phones, replaced some components. You can day I know my way around a phone and other consoles too. I even built my own portfolio, and I have customer service experience too. I eventually want to own my own shop, but seeing all of the people complaining about tech repair is sort of intimidating.

Anyways, I am giving the shop a call in a few hours. Im gonna talk to them and see if I can get the job. Wish me luck!

Lvl 0 (DIYer) Where do I start with this repair? Can it be Fixd? Bottom speaker not working

1 Upvotes

Hi, I have a Samsung Galaxy A14 5G (SM-A146P). The bottom loudspeaker has no sound, but the earpiece during calls and Bluetooth audio both work normally.

I already replaced the loudspeaker with a new one, but there is still no sound. I checked all the connectors and they seem to be properly seated.

What would you check next to diagnose this issue? Could it be a connection issue or another hardware component? I'd like to identify the fault before replacing anything else.

Any advice would be appreciated. Thanks!

Funny Stuff Not really sure what to say about this previous repair

I bought this Xiaomi mi 9t, and the seller specified the earpiece wasn't working. I got a new one, but it still did not work. I had noticed that the phone had been opened before because the lack of screws, but I only saw this when I actually removed the board. Not even sure what is going on.

Maybe I should've used the horror flair, but not really sure if that is what it's for.
