No special tools (pulls out hydro plasma gun)

Holy schnitzels this worked. I waited almost 6 years to get the pics of my sons birth off my dead LG G4. Took less time to to do this fix than it did to transfer all my pics off. My wife is unbelievably happy. You see, my phone died (boot loop) just after we took pics of her giving birth. It died in the delivery room. We thought they were lost forever. Thanks!!!

This is best video I've seen on youtube for DIY LG G4 bootloop repair, and also excellent honest advice - that this is only temporary repair and all important data should be transferred out of the phone immedietly. I would suggest if you can't get a hot air rework station, at least "calibrate" the hot air gun by putting a piece of lead free solder on a penny and see how long it takes hot air gun to melt it.

The internal design of the G4 is so practical, I remember how it's a pain in the ass to open a Samsung S9. You're amazing for finding the solution, you may have stopped the beginning of LG downfall if you had found this solution earlier.

I bought a battery by itself like others did but that not works for me, so I found your video, watched and close it after I memorize what you did now I am here saying THANK YOU!

OMG! it only bloody worked! first ever yt self-help vid I've watched from start to finish & I was so surprised I nearly dropped the fone after it powered up 👍🏻

This worked perfectly for me, thank you so much!!! I bought a $14 heat gun from a discount hardware store, and used it on the low setting. I was worried how long to heat it, and how close, so I literally played your video while I copied your movements. I didn't have any thermal paste, so I skipped that step for now. But I reassembled it, put the battery in, and it powered up without problem!

LG, Life’s Good LIFES NOT GOOD IF YALL LG COMPANY FIX THIS OVERHEATING PROBLEM ITS LIKE MY PHONE HAS A FEVER EVERYDAY!

Thanks for the video. I got my phone working in no time and got all my data from it backed up.

I followed all your steps- and it worked !!!!! alhamdullilah

I’m really surprised that my phone come to life . Thank you for detail and accurate explanation

granted the title may be slightly misleading, as per everyone's hurt feelings here, this was a darn good tutorial. Completed in about 10min, so far seems to be working. Good stuff.

Finally resolved my boot issue with this phone. Thank you for this video. I have an extra glorified music player, now. My equipment: fingernail, small Philips head, Dyson hairdryer, small piece of paper, and aluminum foil. Wish I had this fix 4 years ago.

Did not have a hair dryer or a heatgun, so just held it above electric stove. Fixed it, so yeah, no need for special tools :D Thanks for the video

Easy fix! Thank you so much for uploading this video brother's phone had this problem and he asked me if i could fix it for him at first, didn't work but that was because I was being extra careful with heating the components (only heated the cpu for 2 mins/overrated my hair dryer) but heating it for 6~mins solved the problem! Thanks again

This why i had my own LG G4 thrown in the trash and I will never buy anything again from LG .

Great job I had a LG v10 and it had the booting loop like that, probably was a battery are a bad mother bored. Thank you

Swap batteries to fix the LG4 bootloop? I understand why a loose processor would cause the boot loop, but why would a different battery solve the problem?

Thanks for the instructions. I just funneled hot air for 5 minutes on the processor using a common hairdryer. It worked immediately! I use an Lg g Flex 2 which kept working properly for 3 years. Then started the bootloop, which made it very hard for the device to start. And when it managed to start, it would only work for a few minutes until it would start rebooting continuously and so becoming useless. Unfortunately I kept insisting to try to turn it on and even managed to do the factory reset, until the device became quite dead. One day it stopped turning on and did not charge even. So then I replaced the battery because, like it is mentioned on this video, I heard that it could solve the problem of the bootloop, but nothing happened. It remained dead and would not charge either. I don't know what would have happened if I had replaced the battery immediately when the bootloop started. So just using the hairdryer for 5 minutes made it work! It immediately started charging and turned on and works properly for the moment. I don't know how long will it last, but if it dies again I know that I can repair it by replacing the motherboard. Tip : I used aluminum foil on the end of my hairdryer to create a tube with a smaller diameter to make it more effective.

It worked for a couple hours! Enough time to get my files back! Thanks!

Awesome!! Thanks iSmart for this helpful video This method can also be helpful to other series of LG phones with the same boot loop problems. I've changed my LG G Flex 2 Battery and it only worked for a month then started to boot loop again. Problem - CPU over heat when it restarts and wants to resume opened applications. Solution - Put it inside a deep freezer for about 3 mins, then once your phone starts, close opened apps specially CPU demanding apps and WiFi. You can "under volt the CPU" for a permanent solution :)

It actually worked!!! I suggest you remove the SIM card while heating though... mine is a little melted now🤣

It also works with hairdryer for 5 mins. It wasnt so unbearable hot. I used a thin chocolate carton paper (usually premium chocolates and 200g chocolates have carton paper) instead of business card. And I used wrigley's gum alu paper as heat sink, and I used a simple paper glue to stick it in place. It was totally okay for that 15 mins while I saved all my data from internal storage.

Great thorough tutorial. Thank you for sharing!

So many thanks for LG G4 reboot loop fix.

Hi my name is john patrick palisoc iwant you to know that video is so awsome itry this tutorual in my lg and wow it works !!thank you for this video . Iwant to learn more came from you :)

Thank you for this. Fixed mine by heating the cpu chip with hot air gun at about 250 degree celsius for 3 minutes and i put thermal pad 2mm thick on the chip but it had too much pressure maybe 1.5mm would do. Phone is now running with no issues 4 days from now

"no special skills or tools needed" *proceeds to take apart phone with tools and use heat gun*

Holy crow this worked flawlessly for me! Thanks so much!

Worked well! Unbelievable!!.... Thank you!

Good gob thank you Where i can find the plastic part with the 10 screws which keeps the external cover?some of the teeths are broken thank you.

The principal is sound. I am not saying you did this wrong. On the contrary, it's excellent. If I may offer a couple of points for your interest...? Seeing as how there already isn't much room in the phone for stuff, a more permanent fix, would be to ditch the cardboard, business card, or whatever, as it is more of an insulator, than the tin foil. Doing a 2, 3 or 4 layer of only the tin foil to fill in the tiny gap, won't have a tendency to push the back side of the processor against the back of the screen, with too much force (and at this scale of tolerance, it is considered BRUTE force!). The biz card is what makes it a less than idea solution, on several levels. Ditch it. You also might use thermal paste, instead of what you did use, even though nothing is intended to be applied anywhere, inside these phones. Thermal paste has the best chance at filling this role, as it does not interact with motherboard/SMD materials, and will contribute to the heat transfer. Thank you for this tutorial, and I hope you will accept my comments in the spirit of fostering the continuing the conversation, between those of us in the tech-space.

very good ! your Video help a lot to repair my smartphone. Thanks

Great video and explanation, i hope mine works. Thank you

My LG G4 does not turn on at all. Does this trick help? The battery is fine, I measured voltage with a multi-meter.

How did the chip get hot enough without burning your fingers?

Will this technique work for an LG Rebel 4? Thank you so much!!

Thank you very much my friend. Your movie helped me a lot, I thank you

I have a lg g4 with the the same problem but i dont have a heat gun or hair dryer what can i use to get it hot enough to fix it

great work champ

can I also put it in oven? instead of using heat gun or hair dryer?

Thanks bro it worked i used a hairdreyer it was quick and easy😄😄😄😄😄

Thanks for this. My G3 has just died in the past week. I may just try this trick. I don't have much to lose, except the money to buy another phone. I fear that it's gone past this point though.

incredible thank you!

Thank you a lot, for me it is working. I recommend everyone to try!

If it is a soldering problem, will reballing the processor be a more permanent solution?

Hi the battery has almost gone for my lg g4 model ..could you sugguest from where to get 1 original one...please help

This is so funny I remember having this problem but I still like lg anyways lg fan, now I'm with the lg g8s

If you have hair dryer , it is a good Idea to get tin foil wrap it around the top of the hair dryer and help you focus the heat better and help Direct the heat on the processor as opposed to everywhere , because the hair dryer is not as intense as the heating gun.✌

thanks man u saved my life it really works big thumbs up

Good .. My phone need to repairing i think it s expose to heat and work than shout down again ..

Tip : DONT use the fast charger provided in the box. It gives 9 volt in the super charger mode wich is degrading the battey quickly and causing overheating issues. Use a standars 5v 2a charger or even better put the cable into usb port on your laptop or computer.Its not worth gambling,forget the super charger.. Heat kills electronic components and battery and causes the boot loop

Hi.i hv same problem.i want to ask is there a way to change the processor on it so that it can start and i can retrieve my locked photos??

This is epic, thanks!

I tried thermal paste and heat, didn't work. What temp on heat?

hello, my lg is working thanks to your tuto but the phone is getting soooo warm when im using it (i fix it 1h ago). Should i stop using it in this condition ?

Hi this Is Valerio from Italy. I'm facing a new issue with my zuk z2 pro. I was using my phone normally. I didn't install any new app or upgrade of any kind. After I switched off my mobile restarting it's stuck on zuk logo and instead of charging os It won't boot and recharges zuk logo. It makes me wonder to a softbrick or bootloop but I can't understand why. Could It Be a software or hardware issue? I Need desperatly datas. Is there any way to start os this way? Thanks in Advance.

Hello dear, I watched your video but I used hair dryer but it didn’t on. It’s showing the same issue. What should I do

Thank you very much, I managed to recover my LG G4

Can i put thermal paste istead of aluminium foil ?

i have the same issue but on my lg v20. how do you fix

I phone dose not getting stuck but it drains phone batteries fast. I change it 100% when i turn on the phone phone change get 100 to 40 or some time 3%. I change my batteries 3 times but nothing happened. So my question is it also have the same problem. And can i fix it?

What temperature is your gun? What temperature for how long? Plus, if the issue was not loose contact but only heat transfer during boot, could we put the phone in freezer for some time and then turn it on?

Thank you so much, it worked

I have a dell latitude 2 n 1 tablet and can't get it unlocked from the dell security lock can u help please

Merci ya3tik saha khoya

Need help somehing strsnge ppeared on my lg g5 after trying to turn it on. An exclamation mark appeared on the left inside a phone with a cross on the botton amd an arrow in between a green circle

Hi, ismart I have been watching your videos for a long time now, I have what is practically a brand new LG G4 it is the best version of the LG G4 phone you can get, it is the one from India, I can't remember now, I think it's the 820 or something, it takes two SIM cards but in your video, you mentioned the possibility of getting a new battery sorting out the Boot loop, I wonder if you can help me decide, if perhaps my phone is suitable for the new battery because it will not charge and when I get a small change into it for like half a minute maybe it will go into a bootloop but someone else,I also said to me that at the fact that mine will not charge is more symptomatic with needing a new battery what do you think. I always liked the phone and it was a pretty good phone the camera was second to none actually at the time they were around 2 I think they were supposed to be the best camera in the world at the time all of the phones lunch but I have a lot of information and pictures in the phone that I would like to get out plus I would also like to get the phone going again what do you think

Sir I updated my phone then after a few days it got bot looped and I can't reboot it because it shuts down when I tried to.

how about LG k350 is corrupt ang not working properly?

Thx very much! It worked

LG makes experienced technician out of its owners. I own a G8, no problems so far I can't wait to initiate my career.

could you not use just the foil and thermal paste for better heat wicking?

Any substitute for the sticky goop this guy used

Thank you so much

I was just trying to get some files from my old phone and was confused by how my phone kept saying boot failure when it worked fine a couple months ago. But then again left it in a heat storage so :/

Hi I have an lg g8x thinq stuck in boot loop. I know this is not unusual to these phones. Intuitively I knew the processor was confused and could not load. I fixed 3 different times by patiently hard starting/rebooting...until got back info. When it shuts off on its own I have to start this whole process again. It has been several days of working on it this last time and it gets all the way to home screen on occasion w out loading apps just like b4 which was a sign i was getting close to it loading on further attempts. But now instead of loading apps eventually it goes from what i described to a white screen...and once from white to pale slightly yellow screen b4 reboot. I have tried putting the phone in freezer w protective baggy and it works better for a while in getting to homescreen pic b4 it gets overly hot but can get past this last hurdle. I.portant info on device that can't loose. Don't care bout phone. Any help us greatly appreciated. Afraid of the heat gun option.

I have a problem will my lgp769 shock on loading screen

Hi iSmart, My wife got a bit of rain water in the usb-c charging port on her LG V20 and shortly after went to charge it. After it ruined the cable by getting hot, I noticed a the charging port also looked slight melted inside the phone. It worked for a few more days but was picky on what charger it worked with. Eventually, this phone started to boot loop and now we cant get it back on at all to recover the data on the phone. It just boot loops. Any suggestions? BTW.. I'm comfortable taking the phone apart, have all the tools, have replaced screens several times and work in IT.

Thanks alot. It work for me too

Worked for me. Ty.

Did this a few times, still stuck in Boot loop also replaced the battery. Wish LG would have just replaced any phone that has this issue. I lost 200 bucks, phone was only 90 days out but turned to be out of the 1 year warranty.

thank you so much it worked

Thanks its really works

gonna utilize this since my lg g4 has bootlooped to death...

hello i have a phone , lg glex2 but a few years ago he dead :)😅 i mean , my phone was off one second and never work again . i went to fix that and the sayed this is for board and i don't have this part ,, now i know you i want to say what should to do ?my phone will fix again ?

i tried your technique but it didn't work(ps :i have the LG G4 stylus). i don't know what is the problem i tried everything that you did in the video. can you give me an advice? thx

Can work at LG K350 Sirr!?

"no special skills or tools needed" lol

Hello. I have an LG Stylo 3, semi bad condition but it has all my information. My phone was working until Wednesday now it willnstart (lg) screen but will not turn on. Repair place mentioned it was the motherboard, could it be the same issue? I just need it to turn on long enough to do a backup.

Hello! Thank you for the tip! Unfortunately it worked for 5 min, then it got back to the boot loop. What else may be done? Should I apply heat for more time? I used a hairdryer. If this is a temporary fix, what would a permanent fix be?

Work for LG k530dy ?

Very good bro

Uses screw on the video Tools: am I joke to you
