iPhone 7 Stuck or "Hung" on Apple logo and looping (Nothing left out)

[@thinklab4598]

I started microsoldering with a $100 USB microscope and a $80 2in1 rework station. The first repair I ever attempted was the iPhone 7 audio ic and got it first go with no sweat. I have done over 20 of them now first attempt with out a hiccup until the other day I was telling my buddy how much of a legend I was and the chip flipped up....After a second reball and reflow she was all good. I have always used Marks gravity drop method and it is hard to fuck up. 2years later I am geared up with hakko, quick, amscope, ect and own every piece of gear anyone could ever want; I predominantly work on MacBooks now and make a very lucrative living from this art. A lot of my success can be attributed to you Jason, and Louis, Jessa, Mark, Paul, and Paul D. Thanks heaps guys and long live the champions!

I'm about 15 minutes in to the video, and planning on watching the rest. Just wanted to say thanks for uploading this. Really interesting to watch these kinds of videos and learn some troubleshooting techniques for diagnosing my own hardware problems. In the case of recent iPhone models, I've now learned to leave it to people with better tools and more patience than I have. Will definitely keep you in mind should I ever have a phone die. Truly appreciate your sharing.

LOL, I know that phone! That's my daughters iPhone7, thus the rose color. She's in ROTA Spain right now and sent it to me to get it fixed. I had quit a few folks to choose from, but I'm hooked on watching Jason's vids!!! Kudos Jason for not making me look like a noob by not trying to re-install the ipsw and update (5:53)!! No worries about the return; crap happens. You and Angie have a crazy fast turn over time. I appreciate your work and videos!! DnAustin

This is an amazing job! And im glad that your hands doesnt shakeing when you soldering this tiny wire, wow

[@illili32]

You're definitely right about the finesse for removing the audio ic. I haven't developed the flip technique, it's on my list. Currently I prefer moving the chip laterally first to confirm all pads are wetting temp before pulling up. The amount of heat required feels like it's almost twice as much as the Meson was for the 6/6+. I'm amazed at how well this board eats heat.

[@stefanmarius3087]

Hello. to fix pin C12 audio and do not need to remove it, you can insert a wire. the thread is inserted through the side of the audio chip by removing the bumpers (only the nand side) and r3201. this variant is tested and running, it raises the risk of disturbing the baseband

Definitely worth trying :)

[@aktisfm]

My iPhone has been stuck in a bootloop for the past month, and only now am I taking it to the apple store to repair it. I was very worried about having to do a full restore and erasing all the data off of my phone, especially since I don't have any recent backups to restore from and I have all my important data on the phone. This gave me a bit of hope when it comes to getting a my phone to a place where I could back it up for good measure and transfer the data to a new device (since I will be getting a new phone with more storage anyway).

[@donkeedic366]

cant agree more. My phone iphone 7 stopped working out of nowhere a few days ago and I'm distraught at losing all my pictures for the past year. Fucking apple products

[@aktisfm]

@@Angelahuofficial unfortunately yes. I had to restore from my most recent backup, which was from december of last year. But i found a bunch of those photos and it's alright now, but if i hadn't posted them or sent them to others using platforms other than imessage (since messages got deleted as well) they were lost to oblivion. Honestly screw apple, we shouldn't have to pay extra for icloud storage just to keep all our data saved.

[@aktisfm]

@@Angelahuofficial I only found those photo's because I sent them to others using chat services that weren't connected to my phone storage itself (like instagram chat, discord, and other things). If you don't have any backups and haven't sent those photos to anyone using services like that, I'm sorry, you're out of luck.

[@sspro7768]

The way you film makes me want to watch this video even tho i care nothing for all the technical stuff. I found this video quite therapeutic. Strange but nice !

[@MM-dy3ws]

Good job. Although you didn't insulate the wire jumper. Which could easily have come loose when you refitted the audio IC.

[@OnYourSquare]

There's no need. The wire, the trace and that leg of the IC, all solidify together. The only real danger of bridging is while the chip is being heated.

[@ElivinMendez]

Hey man, thanks for what you do. I had my iPhone repaired last year by you and has been working amazingly great! It was a different issue than this one. Unfortunately, I ran into this issue as well. I was transferring my data and I left my phone unattended and I saw the black screen with the white apple logo on it (so similar to this except for what the screen looked like) I will more than likely be sending it back to you because I want keep my data intact... I do not want to lose it. Now, quick question: did it take you to the welcome screen because the phone was already reset or will the repair reset the phone and make you lose all data?

[@graphicscardtech3167]

My iPhone 7 Plus is stuck on Apple logo I reball audio ic and nothing there’s no short on baseband could be the pmic baseband?

[@ststele]

It would most likely be nand, cpu or ram. After iOS 12, they will boot without baseband. I run into nand faults really frequently tho. Especially 128gb phones for some reason. I really should make a new video to update this one.

Hi, Is this sympthom familiar? iPhone 7 boot loops, but if I disconnect the front camera flex, it starts, but touch-id and home button doesn't work. But, if I reconnect the front camera AND disconnect the home button, the phone starts too.. I just can't have both parts connected at the same time. I've tried new screen and new front camera flex. Motherboard issue? In that case, which chip? One of those in your video? Btw. ear-speaker works, but not front camera, prox or light sensor.

[@mrsemifixit]

Any tips on pinpointing issues related to baseband reboots without just trying new bb pmic or reballing bb cpu?

[@ststele]

Common flaws is the best I can say here. Many times I go strait for checking shorts on baseband power lines (specifically PP_1V0_SMPS5) because it saves me from wasting too much time on a no-fix. If PP_1V0_SMPS5 is shorted, it's the end of my repair. No heat, no soldering iron, no checking for shorted caps. It's the baseband CPU shorted. I think just about any line could get broken though so outside of detectable shorts, we are left with checking for continuity and comparing diode mode measurements against known good boards.

[@mrsemifixit]

[@ststele]

I bought it from a local insurance agency that used it as a customer checkout counter. I just got lucky that the top-deck was the right height for the microscope post to go through. I drilled a big hole and then mounted the base directly to the bench top. I didn’t plan to do that when I got the bench. It just happened to work after I struggled finding a good spot for the heavy, factory base that came with the microscope stand.

[@kassiethweatt7952]

hi- Enjoy the way you talk and explain. You are so easy to listen to. Glad I found your videos. I am having the worst time with a hand me down iPhone 7 from my brother. I have tried everything- Programs that I have downloaded and trying to put it in recovery mode and so on. The phone is stuck on the logo and that is it. At times I will have charged it the whole night only to take it off the charger and it will not last long. Based on that is this phone fixable? Or should I forget about it and just buy a new one. He had said that it was frozen because he took so many photos of his son that it jammed the phone. Help- I trust your advice. Thank you in advance for any any of your words of wisdom- K

[@markbeshay]

Not sure if you’re still dealing with this issue anymore but although it definitely is fixable, I wouldn’t say it’s worth it. It could very well be a lot cheaper to get a newer iPhone (doesn’t have to be the newest or even brand new) but you’d get a much better deal that way. In terms of your iPhone 7 I’d say put it up on eBay explaining your issue and if nobody’s interested just get the trade in value and use it towards a newer phone with your carrier or sell it for parts through one of those recycling services. Goodluck!!

Over the past 20 years, I have purchased more than 25 cell phones and 15 tablets and not a one has ever had any issues. The list goes from Nokia, Blackberry and on. In the last 5 years, I've been with Samsung. But in Jan 2018 I finally decided to give Apple a try and I was pleasantly surprised. I got an iPhone 7 Plus along with an iPad Pro 12.9 and they have worked great together. I use them every day. I keep them as must as possible out of direct sunlight, leaving them in a HOT CAR and always buy a Great case to protect them. I've watched friends and coworkers treat their cell phones and tablets like a child treat an old toy that they don't want anymore. Also, back in 2014 I picked up an iPad Air 2 for the first time as a main On The Go Tablet and have never looked back. So I must be lucky.

[@brittanyadcock8668]

Out of no where my phone screen went black with the loading on it, but it was still on because I was on the phone with my friend while it was doing this. after I force restarted, it got stuck on the apple logo screen. I do need an update and have been needing to update for a long time now, but now that I hooked my phone up to my computer (the same computer I have used before to update), iTunes is now telling me to respond on my phone to connect... so I cant seem to update or recover or really do anything at all.

[@ststele]

I'm really sorry to hear it. It sounds like yours is hung on an Apple logo like the phone in this video where it starts all the way up to the lock screen (so it thinks) but the display is still showing the startup/Apple screen. So far, it's been the audio chip that causes this sort of a hang up. If you are just trying to run a back up, I could imagine if the phone was a bit warmer or colder at the beginning of start-up, it may go past this without having to do any soldering work. Is very very tiny broken connections that cause it so I think just a temperature difference could affect it to temporarily make it work. The iPhone 7 has been a real lemon. I think I've lost track of the amount of faults that cause them to hang up or loop.
