iPhone 5: No imei, blank baseband iPhone 5 water damage.

Wed, 03 Jun 2015 01:25:55 -0700

I have a problem with a iphone 5 that had water damage.

The iPhone worked fine no problem at all. The only problem it had was making calls. When you made a call you couldnt hear the person or the person couldnt hear you. audio IC problem i think.

So i have opened the shield cleaned the logicboard with isopropanol. After that i made a call and it worked.

So i closed the iphone but after that the problem came back.

Cleaned the logicboard again and put the phone together, i wanted to test the phone, but phone stopped reading sim. I noticed that imei was gone and baseband was blank.

Did some research and could be the U601_RF baseband power supply failure.

I marked where there was corrosion

also a resistor of conductor is been missing from the logicboard.

what kind of component is the missing one ?

With the missing component the sim has been read, and also the live call were successfull.

I want to know how i can troubleshoot which component i need to fix these problems. I have micro soldering experience and the right tools to do this repair.

iPhone 6: Home Button Unresponsive After Water Damage?

Wed, 15 Sep 2021 12:37:03 -0700

My Iphone 6 had recently suffered water damage. The water damage came from an accidental drop into the pool. I did the rice trick and after about 5 days it worked. But, the home button doesn't work. However, it does respond after a few minutes. I have done my research and am recently trying an alcohol trick. I used a cotton ball with a dab of rubbing alcohol and pressed on my home button with a circular motion. I was told that the rubbing alcohol dries up the water, therefore contributing to my thoughts of clearing up any leftover water damage. After this, I have chosen to put it in rice for another day. Any ideas on what I could do, if this doesn't work, without going on the inside of the Iphone?

iPhone 6s: iPhone 6S can't restore error 6 or error 9

Mon, 20 Apr 2020 18:50:18 -0700

Yesterday one of my customers came to me with an iPhone 6s that changed the LCD by himself. After replacement the battery started drain faster than usual, I told him that it is not battery problem but LCD problem and need to be replaced again. He didn't want to pay for other LCD and he insisted to change the battery. This didn't solve the problem and after 7 days of use phone stack on apple logo and started boot loop. then he left the phone charging all night but it didn't help, his last action was to restore the phone but it failed. Now I have the phone and every time I try to restore I see sometimes "error 6" and sometimes "error 9". Does this phone has motherboard issue? Has someone come up against same situation? I would appreciate if someone could help me, thank you!!!

i checked the motherboard by myself with a microscope, i am not so experienced but nothing unusuall and no missing parts near the FPC connectors, but when i push the power button and phone start and try to boot this part of the motherboard get really hot

There is the Memory Chip in this part of the motherboard and i think that this phone is shorted in there. Can someone tell me if this phone can work again or not?

iPhone 5: iPhone 5 Overheating after Water Damage and cleaning

Mon, 11 Dec 2017 23:10:56 -0700

Hi. I went swimming in a saltwater pool for about 30 minutes with my iPhone 5 in my pocket. Never tried to turn it back on. Left it in rice for 4 days, then took it completely apart using the iPhone 5 teardown guide here. Removed the EMI shield, as well. Cleaned the board, connectors, basically everything I could find with 91% alcohol and a small brush. I did not replace the EMI shield... just left it off. I also replaced the battery.

When I plugged the phone in and tried to turn it on, it got really hot to touch on the back of the phone, and the LCD was blank. Took it back apart, cleaned the connectors again and made sure they were seated properly.

After putting it back together, I plugged it in and got the dead battery symbol (meaning the LCD did work). Let it charge for hours, and when I turned it on, I only had 6% battery, got the overheating warning, and the touchscreen was completely unresponsive.

Any ideas what to check next?

iPhone 7 Plus: How do I fix a loose charging port without replacement?

Tue, 10 Mar 2026 23:23:20 -0700

The charging cable was pulled at an angle and it wasn't removed properly. Now when a charging cable is inserted, it goes in but there is no audible click and is loosely fitting. Is there a way to fix this without a port replacement? Is there a way to bend something in the connector so it grips the lightning plug more?

I think it's the wings inside of the lighting plug that are loose but is there a way to bend it inward without a device disassembly? I have a photo of what I am referring to below.

iPhone 7: Touch id Not working on my iPhone 7

Sun, 23 Nov 2025 12:30:16 -0700

So just the other day, I subconsciously just started using my pass code more to unlock my phone, I hadn't realized it until now, but my touch id isn't being accepted anymore.

So I deleted my finger prints, and then added new ones on. It worked for an hour or so and now It just doesn't take anymore. It's denying my fingerprint either, It just does nothing.

iPhone 13: Does replacing the Proximity Sensor flex cable disable face id?

Sun, 15 Jun 2025 23:09:54 -0700

As most of us know, any Apple device with Face I.D. functionality has that functionality linked to the front camera assembly and the proximity sensor flex cable. In past generations, damaging the proximity sensor flex was relatively easy to do on accident, and rendered Face I.D. disabled unless you employ micro-soldering to transfer the flood illuminator to a new flex cable.

I have been searching for an answer about this on the iPhone 13 series. When these phones were first released, screen replacement would disable Face I.D. unless an IC chip on the back of the display assembly was transferred. This has since been changed, but I do not know about the proximity sensor flex. No tutorials or guides that I have found have mentioned anything about transferring the proximity sensor flex cable, so that leads me to believe that it's not necessary anymore as long as you have another one.

So my question is this: Does the proximity sensor flex cable need to be transferred to retain Face I.D. functionality as it has in past generations, or is it no longer linked in the same way that it used to be?

iPhone SE: Water damage, is my iPhone beyond repair?

Tue, 24 Dec 2024 05:22:25 -0700

My iPhone SE was not completely submerged in water, it was face down in a puddle and now my phone is damaged. It still sort of works, I can still use it and it still connects to wifi with a slightly distorted screen. Unfortunately, it doesn't recognise the SIM card and the speakers don't work although the vibrate function still works. I want to get this repaired as soon as possible and plan to take it in to a professional repair place but I'm really worried that it's broken beyond all repair, especially after hearing that water damage is not covered in my phone's warranty and the reputation of iphones breaking.

Is my phone beyond repair or can it be saved?

Thanks in advance!

iPhone 5s: Broken iPhone screen, Now it wont turn on

Tue, 22 Mar 2022 12:04:02 -0700

So I dropped my Iphone and the screen shattered, i mean there was glass on the floor. I continued to use it for a few days until i got a new phone then I put it in my room. I picked it up again a few days ago and plugged it in. Left it over night to charge. I don't get a charging sign, and the phone wont turn on. I've been told to plug it into my computer to see if after a while iTunes will detect it, and i'll know if its just the screen. But I'm wondering if that is what I should do seeing as my phone used to work even with the broken screen.

Any ideas?

iPhone 5c: iPhone 5c dropped > screen blacked out

Sat, 11 Jul 2020 13:56:48 -0700

I dropped my iPhone 5c the other day and watched the screen slowly fade to black. No cracks or anything, the fall couldn't have been from more than waist high onto concrete. The phone fell with the screen up. I've experienced symptoms that have progressed as follows:

First the screen showed a row of white squares at the bottom and that was it. The phone would still ring and I could still answer and field calls with the headset button. When I plugged it in to my computer it would make the "bong" noise every nine seconds or so.

I turned it off and then on again and the squares disappeared. The backlight was still on, while the screen was still nothing but black it was brighter than nothing at all. I could still answer calls and even attempt to communicate with Siri (who would tell me I couldn't access his/her help until I unlocked the phone, which I couldn't do).

I came home from work to a dead phone the next day, I charged it up and now the screen won't illuminate at all, and I can't seem to turn it on and field calls with it anymore. No matter what I do it will no longer ring or make any notification sounds other than the "bong" every nine or so seconds when I have it plugged in to my computer or an outlet.

I've opened it up with the proper tools and checked the cable connections, everything seems in order. What I'm worried about is the possibility of ordering a new screen/display/lcd unit from ifixit and finding out that there is something wrong with the backlight or something worse.

Is there any explanation for why the phone suddenly stopped fielding calls or even ringing? Is there any explanation for the backlight to stop illuminating the screen, even on a blacked out screen?

Any help at all is greatly appreciated. I'd like to figure this out myself and fix it, but I can't pull the trigger without having some belief that I'm doing something that will actually be productive.

Hello Everybody,

I have a problem.

I replaced a iPhone 5s screen and everything goes well like always, but this time the Touch ID doesn't work.

If i go to the settings i see that the Touch ID still has save the finger 1, but on the unlock screen it can't read any finger anymore.

I replaced it with a new one, but i seems that the iPhone 5s doens't accept the new Touch ID flex cable.

Is this impossible to replace?

What can i do ?

Thank you.
