I believe the reason for the boot looping is because when the phone boots up, the phone tries to get in contact with the chips and sensors. When the chip disconnects with the phone, the phone tries to get in contact with the chip, but the chip doesn’t respond. The phone then waits for a response, but it never comes. I had to replace the earpiece in a cheap eBay phone, which kept bootlooping until I replaced the assembly. I believe that is what happens, but I might be wrong.

I bought a 32gb Iphone SE from Best Buy two months ago. I only got it because it was $150 (downside is it is locked to a network) I didn’t care about that as I was only using it as a iPod for work. Anyways, I took it an apple store for WiFi issues. And come to find out, the touch of the screen was bad. Kept failing their diagnostic test. They sent it out for repair and ended up just replacing the whole phone. The best part. The new one they give me isn’t locked to a network.

I have a product red Iphone 7 plus 128gb and 3 months into my ownership of the phone it started getting these exact same symptoms (coincidentally a few days after i watched this video) so i used these steps and contacted apple, i mentioned loop disease and how many 7’s are affected by it but of course they denied ever knowing about it so they just asked me to take it to my nearest apple authorised dealer to send it to them so i did just that and little over a week and a half later i got a message saying that my phone was ready for pick up, walked in the store and got handed a brand new device in the plastic. without this video i wouldn’t of known how to go about the situation and would of ended up spending money on a new device which would of been unnecessary. so i just wanted to say thank you for this quality video and saving me a bunch of money, definitely earned a new subscriber 👍🏽

I’m so jealous that you have so many iPhones and repairing skills😅

I’ve had my iPhone 7 since the year it released (4 years now), and it just today fell victim to this. It’s been through a lot and honestly I had no plans to replace it any time soon, so this is really disappointing. RIP

“I bought this iPhone just to make this video” true fan commitment

You scored by getting it so cheap, and having apple replace it with a brand spanking new one! I have a Matte Black 128gb iphone 7 and love it! Mine is mint inside and out, hopefully I dont have any issues later on, because I plan to have this phone for a long time

If this was Apple in the US, they would've probably inspected the phone and charged you for the aftermarket parts. I also sent a 7 away and used all used OEM parts including the adhesive for water resistance so that Apple could service it. In the end, I got the phone fixed for free!

Honestly one of my favorite videos so far keep it up

Nice! Always enjoy your videos. I'd probably give this a try and give it to my mom :)

Wow thank you for the look out I will definitely check if I have those symptoms

Thanks for this video man, I work for a refurbishing shop, and we have now 4 phones with these exact issues. We googled it, but when I saw you mention Loop disease, it cleared a lot up. I dont know yet if we are going to perform boards repairs or not, but this video made our situation a whole lot easier, thanks mate!

my brother had the loop disease symptoms, took it into apple, and they told him to update his phone to the lastest ios version. he did that and it still didn’t work. he took it back again and they simply said they can’t to anything about it and he needs to buy a new phone. took it to a repair shop and got it fixed. apple in north america sucks bro

So glad I stuck to my 6s+ 128gb. Its been trouble free since brand new in 2015.

Awesome video Hugh and also thanks for showing us your video music names

THANK YOU finally a proper video showing this major problem

Great video once again! Greetings from Czech republic!! :))

I've had my 7 for about two years now and it's had all these same issues since about November

Thank you for making this video, my phone has had loop disease for a while but I didn’t know loop disease was a thing. So I was watching videos then saw this and realized I had it. Hopefully I can get it fixed or get a replacement soon

I have watched 20+ videos of yours in just 2 days. I AM ADDICTED TO YOUR VIDEOS PAL!!!

Nice video keep up the good work!!!

This channel is so underrated it's depressing.

new camera? quality is great. keep up the good work!

Another amazing video like always!

I’ve had my iPhone 7 for over 2 and a half years and it’s gone through a lot, luckily it still works fine

What a great video love your vids thanks for letting me know.

Great videos dude!! I want more restoration ones :3

Nice repair as always

You are so cool keep up the work

Hi Hugh! I've been watching for a few months now and you inspired me to buy several iPhones myself! I've recently picked up a iPhone 6 for £27 that has a rather random boot loop that has gotten me clueless. Whenever it is on charge it will go into a boot loop that you cannot get the phone out of. However when the device is off charge and it still boot loops but when it reaches the apple logo you can hit the phone off a desk three times and the device will boot up as normal. Once booted, the device will show battery percentage for well over 10 seconds before correcting itself to the correct value. And also if you try and unlock the phone immediately after it has booted it will freeze and then proceed to boot loop once again. Once you do eventually get the phone booted and unlocked it works like any iPhone should. Battery has a total capacity of 93% and supporting normal performance. Any advice from yourself or anyone in the comments with experience with this issue who can point me in the right direction would be greatly appreciated!

Great video dude

Very interesting info.... I have a 256gb iphone 7 so I'll be keeping this in mind if something ever happens.....

When hugh didnt post new videos, then im just watching old videos again and again till bloated and died🤧

In the USA, Apple WILL NOT Service or touch ANY device with aftermarket parts like the screen. Please mention that in your video, since this WILL NOT WORK IN THE USA.

Using my iPhone seven plus that has loop disease you literally just diagnosed my phone thanks 🙏

You're a legend dude 😭 I hope it's not late to have a replacement for my 6 plus 😭

What do you tell Apple on how to get it replaced

Is the front camera not working a symptom and restarting it supper long I didn't really understand because my sister has those problems

Thanks Hugh Jeffeys

So I had a phone with loop disease and I noticed all the symptoms, so I just kept rebooting it every time it was happening, and now it works perfectly fine

This also happens when you always have low power mode on. I had a 7+ and always had Low Power mode on to “save my battery “ and it caused a Boot Loop.

My phone was affected

Awesome video Hugh Keep uploading awesome content

Congratulations for 70,000. Subscribers !!!!!

dont they a receipt or any proof that you bought the phone yourself?

What a deal!

Bravo huge Jeffreys So would u recommend going through amazon renewed to get a iPhone 7 Plus?

Another video! As always, it's great!!! ❤

hi there, i have an original Iphone 2G here, with what can only be described as pixel rot, where some whole lines of the LCD are greyed out, and some individual pixels near these lines are also greyed out. I'm happy to send it to you so that you can do a video on the 2G. I'm also in Australia, so please send me a PM if you like.........oh...and i love the videos......keep it up!

its called the audfo ic going out on the phone bro

I love your videos I liked and subbed

This happens to my iPhone too. Exactly the same symptoms as you have.

i have a problem on my iphone 7 where whenever i connect my lightning to headphone adapter and connect my headphones the phone doesnt recognize them and plays music from the speakers even though when i charge my phone theres no problem and i have no issue with voice memos or siri or anything thats displayed above so is it still an audio ic problem?

I had the same problem. I went to the apple store he said they couldn't fix it but apple could buy my phone back for 200 CAD and i can buy a new one for 600-200 =400 CAD. I decide that would not happen and went to my local shop to fix it and they charged me 150 CAD. This is totally wrong they should not say bullshit and actually do something

I love your videos

Thanks for the video - but why did you have to repair the screen before sending it off?

i just folded up a piece of paper (like from a carton box for cigarettes) and put double sided tape on the audio IC part, and put the stand-off screws back in, and my microphone, earpiece, and headphones started working again.

how did you kick it out of the bootloop? n how long did it take? my phone is currently stuck in a bootloop

OMG!! I had this same problem!! I am now on my 3rd iphone 7 that has had this happen

Well done... do we know about how long before they start doing the boot loop? With extreme use?

Hey Hugh! Quick question: I got a new screen for my 4S on 6.1.3. After installing the new screen, I cannot use it with my finger however i can use physical buttons and see the screen. What is this?

I know this is an old video but I need help! I have a iPhone 7 with loop disease and it isn’t at the point yet where it’s in the boot loop but the microphone doesn’t work and it has all the other symptoms. Should I still take it to apple and try get a new one?

Yup my iPhone 7 has these exact symptoms

Boot looping is caused by the audio chip cracking the ball solder joints under it. More, the main board solder ball detaches from the board. The boot up keeps trying to initialize the chip, but can’t finish because the CPU can’t talk to the audio chip. iPad Rehab YT channel has many boot loop videos and Jessa is an expert board level repairer and her videos are very good. The iPhone mainboard is rigidly mounted to the case and there is a flex point if the phone case is bent. That’s why the solder balls break under the audio chip. Great video. Thanks!!

When you buy an iPhone 7 in 2019 doest it still have the loop disease or is it fixed? Please answer

Its causes a boot loop because iOS 11 and later runs a full hardware check before allowing the device to proceed to a booted state. When the AudioIC is not returning any value to this check, or is sending back incomplete data (like if it were damaged or disconnected from the board) then iOS 11 will continue to wait for a response until the system request times out. This is why loop disease is less common on iOS 10

I got a Jet Black iPhone 7. I had the screen and battery replaced at an Apple store a couple weeks ago as well. Hopefully I don't have to worry about loop disease since I can't afford to upgrade to the XR like I would like too.

Nice video I am also watching on an iPhone 7

this is all caused by the audio ic chip coming loose with the solder balls. it costs around £50 to have a professional reball the chup

After making this video expect Apple to to say 'No' to you in future returns of iPhone or iPads.

This is caused by a bad Audio IC control chip on the motherboard, which isn’t easy to fix. The 6 Plus has a similar board issue where the touchscreen often will stop working

Never had mine boot loop, always worked since I bought it

My iPhone SE was doing this, I went to my settings and tried to reset it but every time I pressed the button, it would dim but not do anything, I kept trying and finally I got it to fully reset but when it turned on, it was stuck on the Apple logo, to this day I have an iPhone se that’s stuck turning on, I never jailbroke it it anything.

Good Video

I have an iPhone 7 but I have a iPhone 6 Plus also with Touch Disease, thought i’d open it up as i had not much to loose and a sim card inside seemed to really help, the issue still persists for me but before the phone was totally unusable so I’d say it was worth it.

Yea my both 7 plus had this issue soldering a new memory chip fixes this issue but sometime it also effects the audio chip aswell in that case the board becomes useless as audio chip is also a temporary fix and after that the chip turns bad again

Lööps

Hello! I saw this video and i have the exact same issue. But when i handed the phone over and after some chat with apple support, they wanted me to pay 4000 SEK (~400 Dollars) for an replacement device. The apple support told me that they never heard about this issue and denied the fact that this issue exist. Well i hope i could get a replacement like you in the future... :(

Nice job

Great vid

Hey Hugh, I have been experiencing this problem for about three months now. since I bought the phone first when it came out I thought Apple wouldn't replace it so I wanted to know if Apple would replace it in 2020 since they don't sell iPhone 7's anymore..... pl: I haven't changed any hardware part yet

I'm Italian and I love this channel

my iphone 7 i got from ebay was listed as brand new and worked for a week and then it had loop disease. i believe it happened when i plugged a pair of headphones in it started trying to turn off and was out of control. now ive sent it back and am buying an iphone 8

The audio ic needs replacement when this happens it cost around 25 to actually do it but technicians will charge you around as you have to work on the logic board

if someone could link me where he buys his supplies like from batteries to screens etc please, would be much likely appreciated

Does Apple still do replacements, mines been getting worse over time and Definitely won’t be buying another throw away iPhone, my phone can’t even make calls no more and I can’t even listen to music

Nice stuff

Whoa! This is the first time I found out that the "home button" is actually removable

Dude I got it replaced twice and both of the phones had loop disease

The iPhone 7 at boot will scan the system for sensors and do a official hardware test. If it fails the device will malfunction or won't boot. This is not intended to cause a bug but is a security feature to prevent hardware tampering. A good example of this hardware tampering prevention is the touch ID button being locked with its original iPhone so you cannot replace the old one. Since there are solder issues with the chip the device cannot register the sensors properly so the kernel disables them but if the componet is essential and fails the iPhone can kernel panic and lock up. Like most issues Apple was probably aware of this before launch.

I’ve restored an iPhone 1st gen, 3g, and 3GS. All of which have the hardest mute switch repair

Hugh thanks my 7 I bought to repair has loop disease

Question, as if you’ll even see this, but will they still replace it? Like current date. For awhile now I’ve thought it was the gray speaker bug…

What I'm thinking: The boot loop may be caused by a system driver (aka an audio controller kext that is required) is unable to communicate with the system and thus freezes the system waiting for the device to communicate but then times out then reboots, This also happens on macOS with any kext...

Man mine started doing it. It goes into the boot loop for like 10 minutes before starting, can’t use anything other than Bluetooth headphones, mic and earpiece speaker don’t work, and the cellular modem has recently stopped working

This is very good to know as I have an iPhone 7 plus! 😅

i saw a iphone 7 with locked icloud or whatever its called.. its pretty cheap and in good condition.. is there some way to unlock it for free?

jerry rig everything vs Hugh Jeffreys

Hugh Jeffreys I have the loop disease and I was wondering what were your step on sending it in a getting the new iPhone

Hi hugh Jeffrey I have a question to ask was your iPhone under warranty when the loop disease happened with device
