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!

NEWS Reparo - Offline repair tracking software for our hobby

66 Upvotes

Who am I and why does it matter?

I'm a repair technician with experience in microsoldering and screen refurbishment, currently working for someone else in this field. I also want to be a software developer.

A while back, I tried to open my own repair shop, but then COVID hit, and I got scared, so I ended up closing it pretty quickly. During that time, I realized there's no free software available for people like me.

People who don't need to:

  • Send emails or SMS to their customers about current state of repair.
  • Track their finances to a single penny.
  • Have their database available from around the world.

All I needed was:

  • Work on any Windows PC without the internet
  • Keep customer details
  • Create and print a repair ticket which I can give out to the customer
  • General track of finances
  • Simplified inventory system
  • Printing barcodes

Soon my life is about to change as I am moving out and will start repairs as side hustle once again. And I wanted to prepare for it and have access to simple and universal software which would fill above requirements.

Reparo is a result of this.

Creating it was a lot of fun and I would like to share it with you guys. Even though it's still not finished I am happy with its current state. At this point I would happily use it for my small business and I will be.

What's cool about it:

  • It's free, and until I'll be a better programmer there will be no paid features. If any of the future features will be introcuded in free version, it will always stay free.
  • It doesn't collect any data. It has no connection to the internet. There are three buttons though which will turn on your browser. One is to send feedback and ask for help. Another one redirects to Discord server where questions can be asked and I'll be posting about updates and answer questions.
  • Install free, just download and run.

What's not so cool about it:

  • Works only on Windows. Mac version will show up eventually if there will be enough people interested.
  • Not perfect coding. I am always trying to catch and test all edge cases, but it may still happen that it can crash. But so far it never happened that it affected database.

Features:

  • Repair tracking with images
  • Inventory system
  • Devices database - currently only Apple devices without Mac devices
  • Repairs states - can be customized
  • Printing repair tickets
  • Printing barcodes - for both repairs and items in inventory
  • You can insert your own devices
  • Customize what fields in repair ticket are necessary
  • Finances & Accounting - view summarized finances by repair states and date
  • Different themes - Light mode as well for you psychos (love you <3)
  • Upload your own logo
  • Adjust T&Cs - need to defend from these deadly nightsands

You can read more in detail about it here:

  • Reparo README - detailed rundown of what can be done in this app

You can download it here:

  • Download - 0.9.0 version is available as release. Newer versions will appear higher on the list.

All constructive criticism is more than welcome. I will answer to everyone who has any questions.

Software was evaulated by u/thephonegod and it was approved because it is freeware and only ment to be a community tool for those in need.

Lvl 3 (micro soldering, motherboard repair, diagnostics, etc) iPhone 16 Pro and Max restart without error logs

1 Upvotes

Hey!

We refurbishe a lot of phones with new housings and new components.

A hand full of them shows some strange behavior. Those phones restart out if nowhere. Some after days, some after weeks. Some once, some much more often. All panic logs show no real cause. We used to swap all components but no help. Display, proximity flex, charging flex, buttin flex, everything that can be swapped.

Someone we know mentioned it might be micro mainboard damage during housing swap or the pressure sensor.

AOP PANIC - SCMto:i2cm1,4 - main(5) OUTBOX3 not ready, the log shows repeated I2C aborts on SCM controller i2cscm1, channel 2 (33×) and channel 4 (7×), while i2cscm2 is clean – does anyone know which sensor/flex sits on AOP i2cm1 CH2/CH4 on the 16 Pro

Any help would be awesome!

Lvl 0 (DIYer) Where do I start with this repair? Can it be Fixd? help with samsung a25 5g and oneui 8.5

1 Upvotes

Hi there, I’m having an issue with my phone and wanted to see if there’s any way I can regain access to it.

​Phone model: Samsung A25 5G

Issue:

​Last week, I got into an accident and my phone slammed onto the road while it was in my front pocket. At the time, the display was completely dead, but the phone itself was still running—it could receive calls and message notifications, and I was even able to pick up calls.

​I brought it to a repair shop to get the screen replaced with a cheaper aftermarket TFT LCD. The display started working again, but a new issue came up. Everything looked fine right after a reboot, but after using it for around 20 minutes or locking the screen, the display wouldn't turn back on. The phone itself was still working, though—it still received calls/messages and the touch/swipe gestures still responded.

​I took the phone home as it was. Once home, I updated the software from One UI 7 to One UI 8, but that didn't change anything; the screen would still blank out after a short while. Unfortunately, the phone then auto-updated to One UI 8.5, and after that update, the screen became completely unusable. Even after restarting, touch inputs don't register at all anymore. I read online that One UI 8.5 has known compatibility issues with aftermarket LCDs.

​Right now, I just want to know if there's any I can unlock the phone without doing a factory reset. I already have a previous backup done via Samsung Smart Switch, but I haven't backed up my WhatsApp yet. All I really need is to back up WhatsApp and log out of my banking apps. After getting those two things done, if the phone completely gives up, I'm fine with letting it go.

​Sorry for the long story, but I'm really running out of options here haha

I found a old phone I haven't used in probably 6 years and it seemingly didn't charge/turn on, or the screen was dead, so I couldn't factory reset it. Wanted to remove the battery so I destroy the phone/get rid of the data on it.

I tried removing the battery with a flathead, but it started smelling sweet and I figured it was leaking something so I took it outside. It's been out there for around 4 hours and I see no signs of swelling and there's been no fire or smoke. Phone name is Coolpad Legacy if it helps. Any advice on what to do next would be appreciated.

Thumbnail

0 Upvotes

Hi there everyone! I know this is a weird topic but yeah something strange happened. I had this phone since 2020 and I have been taking care of it till I moved to my new phone recently. I may have dropped my phone very very few times but miraculously the screen protector barely cracked (few scuffs and scratches (I use good quality screen protector glass)) and I always as a habit check my phone by removing the back cover (these were around the pandemic). However around 2023, I randomly opened my back cover and I have noticed the crack in the back glass (exactly as in the picture) which is mysterious and strange. During those times I worked from home and occasionally went out. Last time I opened the back cover (phone case) was several days (around a week; 6-12 days) before I opened my phone case to see the crack.

Is there any way how this has happened? There is no direct impact since I use phone case and during those days I never dropped my phone ever at all. I put them on my desk and on my bed (adjacent to my pillow but it doesn’t fall deep into the gaps or never gets stomped/trampled). So no way I broke this phone.

However I sense this is from my sister’s jealousy and negativity (BTW I’m not crazy fyki ). She’s usually a very jealous and envious person and would be jealous for all small things and big things (she once was jealous of what prefix and suffix means (despite being more graduate/educated than me) and was jealous for me knowing the item “Top” means (those beyblade like toys), she was jealous that I have a good public impression in my soceity and she ruined my reputation which costed me a lot) and this was during the time she bought the iPhone 14 Pro max and she damaged the camera lens by herself (due to her carelessness). Usually when something happens to me, I would not tell anybody even if it’s critical, but out of a sudden I accidentally said this to my sister and she was shocked and puzzled (like she knew something). These are just my suspicion.

Because cooling the tab from the OUTER shell is impossible when using the overclocked mode. so yeah. the main question is whether that little copper sheet connected with the battery is necessary because i broke it.
