before we get started I highly recommend not attempting this project in any way shape or form Apple has made this repair impossible on purpose I did find a few methods that work for removing the back glass on an iPhone 8 and an A+ but the risks involved are extraordinary and your phone might very well end up looking worse after the repair than it did before you start it now that we have that out of the way I am going to attempt this repair while leaving all the guts of the phone intact so let's get started there are a few videos online of people using extreme heat to remove the broken glass on their iPhones the heat is so extreme I figured it might be safer to move to the other end of the thermometer and see how cold we can get the adhesive before it gets brittle and loses its effectiveness so it will break off with the glass putting your phone in a conventional freezer for a few hours will not work since a standard freezer is about zero degrees Fahrenheit or negative 18 degrees Celsius and the epoxy holding the glass to the metal inside of the iPhone is still effective at that temperature if you are considering doing this yourself first of all you're crazy and second make sure you watch this video all the way through I explain a lot my first attempt is with the refrigerant I got off of Amazon it brings the temperature down to about negative 60 degrees Fahrenheit tetrafluoroethylene is the chemical used inside of this spray and it can displace oxygen meaning that if you use it in an area that's not well ventilated you might suffocate and die so try to avoid that part the can was inexpensive and seems to be working for the most part you can see the frost start to accumulate over top of the glass as the temperature drops the lower the temperature the less holding ability the adhesive has under the glass remember right now we're working at about negative 60 degrees Fahrenheit safety glasses are pretty mandatory since glass is basically going everywhere so that negative 60 is working but it's still taking longer than I would like after about 10 minutes I've only cleared 20% of the glass hit that subscribe button if you haven't already and let's take this repair to the next level with a safely liquid that's much much colder liquid nitrogen is involved in our next attempt at removing the glass in the back of an iPhone but don't freak out because it's actually not that hard to get a hold of luckily I'm pretty good friends with the king of random over here and he has a good supply but grant tell us where people can get liquid nitrogen on their own if they need some if you guys want to get some liquid nitrogen it's actually super easy to get it would be a lot closer than you think if you get on Google or yellow pages if everybody uses that anymore look for a welding and gas supply company they're probably gonna have some the only qualifier is you're gonna need some safe way to transport so you're gonna need something like a Dewar it's about dwar Durer it's basically a glorified insulated thermos made for liquid nitrogen so if you have one of those no permits are required and it costs you about $5 per litre if you go in there with something like a thermos you can pick up one of these for maybe 10 or 20 bucks my first one was $5 at Walmart depending on the person you talk to they may let you take some liquid nitrogen there's no guarantee this is gonna work but huge thanks the king of random for attempting this experiment with me let's see what happens all right so now the phone is able to sit inside of the liquid nitrogen and hopefully it gets to temperature we want that back panel and the metal to be about the same and I can hear the 18 heard crafty man even hear the glass cracking hopefully that's the epoxy or the adhesive underneath the glass in the middle alright just getting it back to temperature again keep in mind that there is clear adhesive on the front of the phone holding the front glass to the LCD which is also affected by liquid nitrogen I'm making sure to only allow the back of the phone to dip into the liquid so the screen doesn't get destroyed as the liquid nitrogen evaporates into just regular nitrogen it's a dielectric gas meaning it won't affect the electronic internals of the phone the extreme cold on the other hand might liquid nitrogen is negative 321 degrees Fahrenheit so keeping the liquid off of the internal circuits as much as possible is important there are specific cryogenic machines that circulate liquid nitrogen under a metal plate made specifically for cell phone repair so if you have a repair shop and are doing this on a regular basis you might want to invest in one of those it's a little more controllable than the pure liquid it took about seven minutes to remove all the glass from the iPhone using this liquid nitrogen much quicker than the tetrafluoroethylene the camera lens frame is welded to the metal frame of the iPhone and it might be possible to preserve this but since my lens was already cracked from a previous drop test I'll just crush out the lens with my pliers replacement lenses are pretty inexpensive on Amazon I am removing the camera lens last because glass dust can get inside the optical image stabilization mechanism and cause the focus to stop working like I mentioned before if there is quite a bit that can go wrong during this operation luckily the phone still works and turns on thumbs up for that the lithium battery does need to get back to room temperature before will behave like normal so we were successful in removing the back glass panel what do you think about that I think it looks crazy you know I almost feel like you should just take some epoxy and make see-through epoxy just keep the phone that way cuz that's a pretty intense look I'm actually really surprised that turn back on I mean liquid nitrogen I wasn't sorry about I was just worried about the condition of this phone flow in a way that it's working so what do you think with the liquid nitrogen inside of the phone are we more worried about the contacts like the solder points or the battery being disrupted by the liquid nitrogen what's the weakest point inside with cold temperatures I honestly think contraction is probably gonna be the weakest point because liquid nitrogen itself isn't gonna damage anything it's not going to affect chemically anything inside the phone all its gonna do is contract it's gonna freeze things to the point where they can track so if there's anything in here that's breakable like maybe solder points if those get too cold they could snap but it wouldn't be because of a chemical reaction at all so I love playing with liquid nitrogen for that reason it's very non-toxic itself so very non corrosive it doesn't do any damage it's it's like using pure alcohol in this thing once it's gone it's gone well if you have not seen it grant Thompson has been able to make liquid nitrogen in his basement I will link that video here now let's see what happens when we take it to the opposite end of the temperature spectrum and use heat to try to remove the back glass panel this time I'll be working on a cracked iPhone 8 plus Apple's out of warranty repair for this piece of glass is currently uninit as its effectiveness as the temperature drops past negative 100 now let's see what temperature the iPhone epoxy starts to liquefy at the other end of the temperature spectrum using heat once again while iPhones might survive the extreme temperatures during the short repair there is still plenty that can go wrong so I don't recommend doing any of this to your phone it's much safer just to put your phone in a case or slap a skin on it to hide the cracks and just pretend you never dropped it and if you're mad that I phones aren't repairable but with wallet and get something else one thing I did wrong with this phone as I pulled off the camera lens too early exposing the fragile plastic sensors to feed and glass dust early on if I ever do this again the camera lens should come off last I found this sweet spot to liquify the adhesive around 350 degrees Fahrenheit just hot enough to melt your fingers off and start your house on fire when Steve Jobs and Apple were designing the first iPhone they specifically sealed it shut because these jobs didn't want people fiddling around inside their phones not even to change the battery so this new unrepairable glass design is right on par with what Steve would have wanted if you were still here I learned a lot about Steve Jobs from his biography on audible which I'll link down in the video description if you're into that kind of thing the guy might have been a bit crazy and not so nice to people who want to fix their expensive electronics but his life story is very interesting audible will let you download his book for free with a 30-day trial just go to audible.com slash jerry-rigged or text the word jerry-rigged to 500 500 even if you cancel your trial you get to keep the book it's a win-win I normally listen while I'm at the gym or running outside during the summer months if you remember it took me about seven minutes to clear the glass off the back of the iPhone 8 using liquid nitrogen but as of now it's been about 25 minutes since I started using the heat gun a common hair dryer which I don't own would not be near hot enough for this project you need a heat gun I do feel like the liquid nitrogen was a bit easier it's been hard to keep the phone heated to that blistering 350 degrees it takes to liquify the adhesive under that glass layer as soon as the temperature drops below 300 the adhesive solidifies again after getting all the glass off and letting the funcle' down to room temperature I turned it on and everything is still working lucky for us you can see both phones here side by side now let's get the replacement panels back on the phones fun fact Apple does not sell replacement parts for their phones to the general public anyway so every glass piece you buy is an illegal copy it's not illegal to sell replacement parts for cell phones just replacement parts with the Apple logo on them since that parts trademark I'll still link some of them in the video description though Apple does sue these counterfeit sellers into oblivion every now so let me know if the nickels at stock lucky for us it's kind of like whack-a-mole and another counterfeit seller usually takes their place pretty quickly I would rather buy replacement parts from Apple directly but since they don't allow that here we are I got rid of the white color on my panel and the Apple logo since clear phones are kind of what I do and I can also add on the replacement camera lens at this point with some flexible clear B 7000 adhesive then I can read here the whole thing down to the phone body with double-sided tape it's obviously not water-resistant anymore but that waterproofing was lost when the back was cracked either way I think it looks sweet you can't see the electronics like inside of a Samsung or LG but it's unique a lot of the replacement backs will come with their own adhesive already installed it just depends on which supplier you're buying from you can see how difficult it is to remove the camera lens with all the little welding points along these inner rings but I was able to salvage this one off of the eight plus even if my camera unit did get melted into oblivion the camera units are cheap and I'll replace that from the inside of the phone on a different day it's my fault for not leaving the camera lens and placed longer for protection not too shabby a few scuffs along the aluminum side from the aggressive glass removal but the back glass panel is now crack free what'd I ever do this again probably not but at least now we know that the back glass panel on phones is replaceable with extreme heat or cold and plenty of blood sweat and tears one of the questions you might have is does the wireless charging still work and yes it does work on both phones here in my truck we can see the yellow light come on when the wireless charger starts interacting with the phones and the battery charging indicator pops up as well if you remember from the beginning of this video I have one more cracked iPhone 10 which might be fun to try with dry eyes it's about half as cold as liquid nitrogen but a little bit easier to obtain thanks for making it this far in the video I hope your phone has a long crack free life and don't forget to check out audible in the video
