iPhone SE 2022: Motherboard-related vibro and bootloop issues

Sun, 10 May 2026 19:43:44 -0700

Got a phone from Ebay, from a high-profile seller, listing it as "fully functional", the screen was totaled though. When I received it, I didn't check it's functionality, and got to screen replacement immediately. After I was done, I started it up, and to my dismay vibro didn't work. Insult to an injury - upon plugging in a charger phone goes into a bootloop, and only way to break the loop is unplug the charger. Tried different chassis multiple times, but to no avail, which rules all parts besides from MB. Suspected a software issue, but update didn't help. What could that be, and is there any way to save it?

iPhone 17: iPhone 17 dead after battery depleted

Sat, 09 May 2026 19:11:21 -0700

Hi,

So a family member gave me their iPhone 17 to look at. It is currently stone dead. No signs of life at all. They said the battery was at 1% and then the screen went black (assume battery died). After that they said they could not turn the phone back on. They left it charging and still could not turn it on.

I took a look myself and see it is completely dead. There's nothing on screen. There's no battery icon or anything to say it's low on battery. The screen just remains black.

I tried the force restart method (says to quickly press volume up, then down and then hold the power button until Apple logo appears) which did nothing. I've tried multiple cables, computers and wall outlets. Still same.

I have a USB amp meter and I can see when I connect cable, it cycles between different watts. It regularly jumps from 0 to about 2.1W. I see frequent 2.1W readings but it keeps going back to 0 and then up again (sometimes at a lower wattage). It's like it's trying to charge, but can't for some reason.

The phone is still in warranty period, so it can be returned. However, I'd like to check if there's maybe anything that can be done to bring it back to life as it does seem weird that it just died after the battery went out.

Anyone know what could be wrong? If it's a hardware issue, then I'll just send it back for a replacement. But I am hoping there's a way to bring it back to life as this will be faster than waiting for a replacement. It's not looking promising though.

iPhone 15 Pro: iPhone 15 Pro touch not working on edges after two screen replacements

Fri, 08 May 2026 02:50:05 -0700

I am experiencing touch sensitivity issues specifically on the edges of my iPhone 15 Pro. I have already tried replacing the screen with two different 'premium' replacement units, but the problem persists on both. AssistiveTouch 'jumps' or snaps away when dragged to the edges. What could be causing this if it's not the screen? Could it be a logic board issue, a grounding problem with the spring contacts, or something else?

iPhone 11: Why does my phone screen keep going black?

Fri, 08 May 2026 02:04:21 -0700

So, for the past three days I’ve had this problem with my phone. It started Monday, when I’d woke up to watch a bit of YouTube and my hone just went black. I was worried so I contacted Apple Support. I followed their instructions and nothing prevailed. Being the frugal person I am, I decided to wait out the day to see if eventually my phone would work. After leaving it on the charger for maybe three hours my phone’s screen had become back visible and was on the recovery mode screen. I restored the phone and went on with my day. After this, the same issues occurred the next day maybe 20 hours later. I went through the same steps and the phone came on after hours of being on the charge. Today, my phone has went black for a third time. I’m trying to figure out if there is anyway to stop this or what the problem is? Let me give a little information on the condition, when the screen goes black the touch is still responsive and I can still get notifications. I know the screen is responsive because I can still turn the flashlight on. It also still charges. Please send help as this is getting aggravating.

Hi! I have an iPhone 16e and since the OLED screen gives me some trouble because of the PWM dimming, I was considering buying an LCD, and as far as I have seen online and even in the iFixit guide, the 14 and 16e have the same screen and they are interchangeable; so why the 16e replacement is over 500 euro? I guess it's an error? Otherwise I will buy the replacement for the 14 and hope everything works fine.

iPhone 5c: Touch screen problems after screen replacement

Thu, 07 May 2026 21:09:52 -0700

I have been replacing screens on iphones for quite some time now. The iphone 5c and 5s are a different animal. The last few that I've done have me puzzled. It seems as if once I put them back together, the touch response is all over the place. After a hard reset they work for a while and then when you go to touch an icon, another app may open and not the one you touched. I've swapped out the screen with a different one and it does the same thing. Is there some sort of calibration to do on these new phones? It's getting to the point that I'm going to turn down customers that bring them in to be fixed.

iPhone 13 Pro Max: iPhone 13 Pro Max - restarts every 3 mins / Sensor 0x800

Thu, 07 May 2026 12:04:10 -0700

Hello! I have a question. I recently fought with a heavy patient after several services performed by people who badly damaged the iPhone 13 Pro Max. In general, when it comes to the condition of the device, I immediately say that the tapes were not in the best condition, so one of them was definitely damaged during the next (my) disassembly of the back cover of the phone. I'm taking it on the chest! The situation is that the phone restarts after about 2-3 minutes. Evidently watchdag reports some HW corruption. I checked the logs and it is SMC PANIC ASSERTION FAILED - Sensor 0x800. According to what I found on the internet, it will be a damaged charging port. Given that it works properly, I bet on the tape from the microphone. Both microphones work ok. Hence my question - Can the fact that the microphone and the charging port work properly still mean that the tape is damaged to some extent? Are there people in the room who solved this problem?
