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.
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.
@@dominicksoto6390 Yes, it worked for me! Unfortunately it was temporary, even if I installed a new battery. It lasted for 4 days (stopped working yesterday). But during these 4 days it was working properly and it was able to charge. On the 4th day it stopped working. It would not switch on and if I tried to turn it on, it would only display the LG start logo and then would power off again. So today I repeated the procedure. I used the hairdryer again to heat up the processor and voila! It works again!!! So what should I do? How many times should I repeat that fix with the hairdryer? I think it would be best to install a new motherboard for a permanent fix.
@@ДауренЖумабай-с6ъ Well, it was a temporary fix only. It worked again for 4 days and then died. So I bought a new motherboard for 30 euro from Aliexress, installed it myself and my phone works perfectly until this day. The conclusion is that this kind of video was very instructive and helped me take the initiative and start fixing phones by myself. Now I can build G4s from scratch. You can assemble your own G4 for just 80 euro, buying each part separately from Aliexpress.
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!
@@ΠαναγιώτηςΓκόλφης probably not. Just reheating (with out flux) does not work because broken solder joints temporarily touch to make the phone work, but stress and current eventually break the temporary bond and phone breaks again. That's why the guy used foil to push the chip and make it last bit longer
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.
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 :)
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.
I remember owning this phone. When the bootloops started, I connected it via USB to a laptop and then stuck the phone in the freezer. This kept it going long enough to get my data off.
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.
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 👍🏻
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!
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.
Yeah, just be sure to look for a new phone right away. Did it 3 times, phone worked for 2 days each time and then completely died with no signs of life :D
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.✌
Yes but hair dryer doesn't get hot enough. Best to get a digital cooking thermometer for few bucks and test how hot your hair dryer gets. It needs to be at least 240 deg C to melt lead free solder. If you use hair dryer or hot air gun and don't get temperture hot enough to melt lead free solder, there is good chance LG G4 will simply go completely dead because heating simply made cracks grow wider.
@@ΠαναγιώτηςΓκόλφης No probably not. All these reheating chip methods do not address fundamental issue of oxidized cracks in solder balls. reheating only temporarily bridge the gap.
I have an LG G6 for almost 3 years and it's working perfectly, LG fixed this Boot loop problem, their latest smartphones don't have these problems anymore, you can buy one and use it for how long you want.
@@sonicfanfirst I called LG Spain and despite of knowing that was a massive fabrication problem of thousands of LG G4 around the globe they denied to fix me the motherboard... OK I will never buy LG and I will never recommend LG to any friends/family... that's fair!

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.
Another suggestion would be to use hot air rework station, not general purpose heat gun. It's easy to fry motherboard using powerful general purpose heatgun without any temperature control.
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
I got an easy fix...its called Return it for free repair ! Lol no seriously for real i just returned it at the beginning of october this year i didnt have to pay a dime they said just put it in a box that fits with the paid for shipping label that all i had to do was print and tape up to the box. Just days later they handed me back my lg g4 FIXED (new motherboard) with fresh new battery and i didnt have to pay a dime!

Can you guys please help me get a replacement of my bootlooped phone. Say that let me know what they say
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?
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
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

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?
Don't use hair dryer - temperature is too low to reflow lead free solder. Get cheap hot air rework station like no-brand 858D (on ebay for around $35). If you use general utility heat gun (like in video), it may work but you can easily fry the motherboard as temperature is not controlled.
@@cristianene164 To be honest, even with best hot air reflow station, you can get only temporray fix on LG G4. Why? Because of the unusually crappy lead free solder used by LG for it's ram chip on LG G4. Note, that for LG G3, just reflowing ram/cpu chip stack can produce good results. LG G3 had better quality solder and hence far fewer bootloop failures can be seen. But for LG G4, only permanent solution is to desolder the ram chip and resolder it using good leaded solder. That unfortunately takes good skill with micro soldering.
1. Using heat gun without temperature control is horrible idea 2. PCB should be placed horizontally to avoid elements falling off the board 3. Use proper thermal paste (even silicone one), not flux! 4. All this heating (as it is said in this movie) is usually temporary solution, because in most cases you just warm contacts inside of chip which have failed. If you don't believe me just watch this : ua-cam.com/video/1AcEt073Uds/v-deo.html
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.
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
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?
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.
heat gun is a special tool to me. but hey first i seen of how to get to mother board. i have a LG 52 but it is same back with same switch and camera. i just like to get my contacts transfered. went to phone shop and they give you a shrug and dont even offer to assist. just sell new phone
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 ?
Don't bother with this if you can prove your "NEW" purchase of the LG V10. LG is still repairing the V10 under recall warranty... That's right, the phone is basically still under a recall warranty. Just got mine fixed for free May 22, 2019.
On 7/26/17, This happened to my mom's phone like this. She Purchased it 2/25/16 and it lasted 17 months and a day total. I STILL want to fix this problrm with it.
does that solution is permanent? or just for few mins cause thats what happens when i heat up mine , then again turns of , it only gives me ,3 mins to save and transfer my files and data to pc,,, you know what , No never mind ,it did indeed work,so far has been on for over 6,7 hours hopefully it stay steady and finally permanente . thank you for your tutorial ,👌👌👌
No not permanent. Rejoining cracked solder connections using just heat is only temporary. Flux is needed for successful reflow, but due to epoxy underill, it's not possilbe to apply flux to cracked solder joints.
I got a LG phone my phone keep track off and on off and on off and on and I got a new battery I'm trying to find out what's wrong with it I got T-Mobile thank you
@@angel-xe9fn , unfortunately no, there's a way but it's way complicated. Some paid softwares or tools can help but most of them are scams, they will disappoint you at the end.

@@miboiboi2372 Id be surprised if any house hold dosnt have a small star head screw driver. If not then run out to the store n get a 3 dollar tool to fix it. . .
@@FuskyTheHusky81 im just proving a point because i dont have a star screwdriver and it says *no* special tools needed which makes me click on thinking i wont need anything else
He waited till the end to say that it is a temporary fix
Thank u. It worked. Not as hard as I thought it would be. Question is for how long tho???
Hours or weeks or maybe more
all u need to do is change the battery...thanks for mentioning it
Hahah.
I tried to do so, it didnt work. My LG V10 is now ruined. My wife called me "Demolition man". But I can spend a lot of parts. The screws are all right. LoL I like the V10 because the battery can be changed.
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 :)
Hi! Does it work now?
This is so funny I remember having this problem but I still like lg anyways lg fan, now I'm with the lg g8s
This does work, but you should know that this is a temporary fix. It's only for giving you time to backup all your files and you have to be fast.
I just pop off the back normally it works if not i take the battary out but WHO AM I TO SAY im useing an lg umm K8 4G but im glad who ever has this problem with this type of phone they have ppl like u
How much would it cost to ask you to fix it
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?
Don't use hair dryer - temperature is too low to reflow lead free solder. Get cheap hot air rework station like no-brand 858D (on ebay for around $35). If you use general utility heat gun (like in video), it may work but you can easily fry the motherboard as temperature is not controlled.
@@springer-qb4dv thank you for your reply. I will try it and revert with an update.
@@cristianene164 To be honest, even with best hot air reflow station, you can get only temporray fix on LG G4. Why? Because of the unusually crappy lead free solder used by LG for it's ram chip on LG G4. Note, that for LG G3, just reflowing ram/cpu chip stack can produce good results. LG G3 had better quality solder and hence far fewer bootloop failures can be seen. But for LG G4, only permanent solution is to desolder the ram chip and resolder it using good leaded solder. That unfortunately takes good skill with micro soldering.
Great thorough tutorial. Thank you for sharing!
No tools or easy fix. You took the fucking phone apart!!
1. Using heat gun without temperature control is horrible idea
2. PCB should be placed horizontally to avoid elements falling off the board
3. Use proper thermal paste (even silicone one), not flux!
4. All this heating (as it is said in this movie) is usually temporary solution, because in most cases you just warm contacts inside of chip which have failed. If you don't believe me just watch this : ua-cam.com/video/1AcEt073Uds/v-deo.html
louis is talking about gpu tha fails internally and not the balls to the motherboard, watch again
Great video and explanation, i hope mine works. Thank you
hair dryer will not do anything, and special tools (heat gun) are needed for this repair.
Thanks bro it worked i used a hairdreyer it was quick and easy😄😄😄😄😄
can I also put it in oven? instead of using heat gun or hair dryer?
very good ! your Video help a lot to repair my smartphone. Thanks
Nice bro tnx from Philippines
Thank you very much my friend.
Your movie helped me a lot, I thank you
Thank you very much, I managed to recover my LG G4
it really worked
@@rammyboy9739 it didn't work it just made my screen black
@@HeyShaded loosen the screw that worked for me
@@nerrisamontiero9430 the phone is broken stop buying new phones
>Easy fix
>18 minute video
It only took me 5 mins to do. The explanation was that long but the actual job was easy and quick.
@@skoobie2962 It's not worth it, LG phones are complete shit.
@@skoobie2962 You must be the world's fastest then if you can unscrew within less than a minute and cut out a piece of card for just 5 mins
then don't watch it Mr.stupid - you came here to learn cause you are stupid .. if your time is important then go buy another phone Mr.stupid
Amazing, it worked.
Used my lighter in 2 second intervals then used the foil top sealer from coffee mate can. It's working.
Thank you mate.
gonna utilize this since my lg g4 has bootlooped to death...
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.
How did the chip get hot enough without burning your fingers?
Uses screw on the video
Tools: am I joke to you
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
Terima kasih...ditunggu video selanjutnya...sangat bermanfaat...ilike this tutorial
could you not use just the foil and thermal paste for better heat wicking?
yes, thermal paste is better
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?
I tried that , it worked temporarily
@@iSmart1 LG must be really proud of itself! :)
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.
Also, we had an extra V20 so we just need to recover the phone data.
Holy crow this worked flawlessly for me! Thanks so much!
does your phone still work 4 month later?
does it still work?
@@dmonk926 probably not. Simple reheating/reflow is only temporrary fix.
Will this technique work for an LG Rebel 4? Thank you so much!!
incredible thank you!
I really like the " no special skill/tools". At 2:04, I began to cry.😭
Already followed your step. My G4 H818P still cannot start. now I'm ordering new board from Aliexpress.
Thanks sir.. this method works on my phone😀👍
Thanks its really works
still working?
@@ΠαναγιώτηςΓκόλφης its working 1 r 2 hours den same problem
I used to love LG Phones. This “Bootloop Bullshit” happened to me 3 times. I went iPhone and haven’t looked back since 🤗
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.
Merci ya3tik saha khoya
Thank you so much
heat gun is a special tool to me. but hey first i seen of how to get to mother board. i have a LG 52 but it is same back with same switch and camera. i just like to get my contacts transfered. went to phone shop and they give you a shrug and dont even offer to assist. just sell new phone
have you tried using LG Mobile Switch?
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 ?
Don't bother with this if you can prove your "NEW" purchase of the LG V10. LG is still repairing the V10 under recall warranty... That's right, the phone is basically still under a recall warranty. Just got mine fixed for free May 22, 2019.
what was the procedure?
Thank you very much, it worked.
How did yrs work can you help me plz
@@sheilanakalema364 died completely some time after, couldn't revive it anymore
still at least I managed to save the data
Good .. My phone need to repairing i think it s expose to heat and work than shout down again ..
This is a great video! Unfortunately, it works but only for a few minutes then it goes in the bootloop again. Any tips regarding this? Thanks!
It happened to me too I was only able to retrieve one picture
On 7/26/17, This happened to my mom's phone like this. She Purchased it 2/25/16 and it lasted 17 months and a day total. I STILL want to fix this problrm with it.
If it is a soldering problem, will reballing the processor be a more permanent solution?
does that solution is permanent? or just for few mins cause thats what happens when i heat up mine , then again turns of , it only gives me ,3 mins to save and transfer my files and data to pc,,, you know what , No never mind ,it did indeed work,so far
has been on for over 6,7 hours hopefully it stay steady and finally permanente . thank you for your tutorial ,👌👌👌
No not permanent. Rejoining cracked solder connections using just heat is only temporary. Flux is needed for successful reflow, but due to epoxy underill, it's not possilbe to apply flux to cracked solder joints.
great work champ
That really work 4 me thank
still working???
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
What was the exact reason you heat up your motherboard ?
solder ball between ram and cpu stack is cracked. Heating the solder above 220 deg C will bridge the cracked solder balls temporarily
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 so much
it worked
what lg u got if you dont mind saying
I got a LG phone my phone keep track off and on off and on off and on and I got a new battery I'm trying to find out what's wrong with it I got T-Mobile thank you
Any substitute for the sticky goop this guy used
It nah work buh give thanks fi detailed, torough vid brethren! Nuff respect!
Very good bro
LG Aristor keeps rebooting. From LG logo to T mobile to home screen, then back to LG logo. Do you have an idea how to fix it?
Try to hard reset it
iSmart Will this cause personal data loss? Phone is not important but personal data are.
Yes, hard reset will erase all your data
iSmart Is there a way to recover the personal data before hard reset?
@@angel-xe9fn , unfortunately no, there's a way but it's way complicated. Some paid softwares or tools can help but most of them are scams, they will disappoint you at the end.
As I was using the same type of phone, it just went off. I tried charging but wasn't working till now, tried all those procedures but did not work. I would like you to give me some advice. Thank you. JUSTICE (UGANDA)
