Thank you SO much for the tutorial! I was able to get it fixed on the first run. Also added the heat sink to make sure it stayed cool while the data was being transferred. Worked perfectly, all data saved!! Gonna keep the V10 as a backup phone
I have collected three LG V10's that over the years have suffered this boot loop issue. I had forgotten about two of them until it recently happened to my wife's phone. I successfully revived all three phones and all tests look good. Now I have to figure out what to do with them. THANK YOU SO MUCH!!!!
I have an LG V10, it died on August of last year, after a few months I decided to revive it and bought a new mainboard and immediately installed the copper heatsink, but i replaced the thermal pad with actual thermal paste, works like a charm, no more overheating, and this thing flies, for a 2015 phone, this is still amazing, it's such a shame that such a good phone is prone to this issue though, gonna upgrade to V40 asap :) thx for making this video, it saved my phone
As a previous owner of three different G Flex 2 units, I can say they are extremely prone to bootloop. Many show up on eBay with this issue and many reports are on forums like XDA and Reddit. However, the media and even lawsuits never seem to cover this phone as part of the LG bootloop discussion. It is likely due to so few users after all the bad Snapdragon 810 news that it runs hot and thermal throttles often. That very issue combined with the poor LG manufacturing quality (G Flex 2 was made around same time as the G4/V10 and inside layout is very similar) make GF2 units exceptionally vulnerable to bootlooping. Fortunately the heatsink mod in this video can help reduce bootloop risk. Sometimes a battery swap is needed as well.
I used thermal paste por pc and the copper paper and the temps drops 10°C. worth the risk if you apply it properly and isolate the circuits around with tape
I have 2 v10(vs990) both have a boot problem and I got my hot air rework station out set the temp at 300c and set the air flow at 1 and timed it at 1 min. I don't think it was to long of a time it took 3 tries . both phones are fully working now I just thought I would share the temp and air settings Thank you
@@cyberpilot6512 Yes 220c is too low to melt crap unleaded solder used by LG. Need to push 300C to get it to flow. It's only temporary fix, and will bootloop again, unless you desolder the ram chip and replace lead free solder with good leaded solder.
You Saved my life, Thank you so much. I repaired my phone by myself. If your phone Stuck on Logo Please repeat Heater Steps. -------------------------------------------------------------------------------------------------------------------------- Your Videos are AWESOME.
I'm glad it work for you 😊 I suggest you immediately backup important data because we can't tell for sure how bad the damage is and when the bootloop happen again. I think i'm lucky enough that since this video uploaded till today, my phone still working fine (for proof, you can see my recently uploaded video is about this phone (LG V10) review).

Lg is the worst. I have never had this problem with any other brand phone. But all lg brand seems to have this problem. Yet the company do nothing about it
Instead of thermal tape it'd probably be better to use thermal paste used between PC CPUs and heatsinks, like Arctic Silver. Can be a little messy, but would probably give slightly better thermal conductivity.
For anyone wonder if this works I can confirm that it does however results may vary. In my experience of trying to revive the v10 (of which I have tried a few of the DIY methods) this one feels like the one that has the best chance of success. However my v10 lasted for about 24 hours after reviving it via this method opposed to the 20 minutes I got from just firing the whole motherboard in the oven. If you're in a position where you need to get something important out of your phone like say a contact then save yourself the efforts and fling it in the oven but if it's more transferring photos and other media that takes a while then this is definitely your best shot. I was able to move a few gb worth or data, browse YT for a while and then the next day my gf was testing it by playing candy crush on it and that's when it started looping again. Realistically I could probably heat up the cpu again and try to refix the solder but honestly I think it's just a patch on a sinking ship and I wouldn't advise people to try this if they are expecting to get even a few months outta their phone. Still great video, and all the best to anyone attempting it.
@@GlakeGG lol yeah man. It was a while ago, I saw a vid on yt about doing it. If I remember rightly then it was about 180 degrees and for around 5 minutes. Make sure to preheat your oven lol.
Reflowing ram/cpu stack is only temporary fix for LG G4/V10. Good for saving data from phone, but that's about it. Only permanent fix is to desolder ram chip, replace crap lead free solder with good leaded solder
Unhelpful way another method on another channel much better with the liquid heat sink worked well for me now 7 months no problems at all thank to Android Egypt One method.
funny mine was stuck in "life is good" and no longer boot past that. few months later it wont boot anymore just black screen even charging animation no longer shows up.
Worked great for me, at first try. I blowed air on cpu 3 times: 2min. - 1min. - 1min. (with a pause between the heatings). Then I put two layers of excellent thermal pad (17W/mK) bought on FrozenCpu.com Many thanks for the video!
The electrical tape method worked for my sister's V10 but the screen now has a subtle little burn mark right where I set the fix. Also the top screen (second screen) started to leak the backlight a little bit. Still, she got a working phone from her drawer again. She said she will never buy an LG phone again.
I have a strange issue with an LG Stylo 2 Plus handed down to me from an aunt. What happens is: sometimes when the phone overheats, the phone shuts down and refuses to reboot beyond the LG logo unless I first plug it into a USB charger. This happens to me at various battery charge levels depending on how continuously I use the phone: when I use it sparingly or moderately (with phone breaks in between), I get down to about 23% charge before the phone turns off; when I make heavy use of it, then the shutdown happens somewhere between 40% & 50% levels; and even once this shutdown happened to me earlier at 57% while using the camera. And everytime this issue happens to me, the CPU area feels abnormally hot and refuses to either turn back on or boot up beyond the LG logo, but inexplicably, when I immediately plug it into a USB charger or computer (with the CPU still feeling abnormally hot), the phone boots up normally and even reaches the home screen (with that CPU still hot!). What do you think could be going on with my Stylo 2 Plus?
@Danlerie Montoya Tried it and in 99% of the time it doesn’t help. Only plugging it to USB power will wake it up again, no matter how long I wait for it to cool down. But it doesn’t matter anymore - I replaced the battery and it seems the problem vanished. And I smelled the other battery and it smelled toxic. No good, must recycle it soon!
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.
My phone has only just started the boot loop problem and i'm desperate to retrieve my data because it contain photos of my children. appreciate your advice, best wishes
it worked for me three times..it worked each time for a month or more..but i did not use copper plate...my mistake....it works just prevent it from overheating ..
No it's not long term fix. The reason is that LG used crap lead free solder in LG G4/V10 which caused bootloop issue, and it will fail again. Only permanently fix is to desolder the ram chip and resolder with good lead solder.
Well, it all depends on how bad the damage is. Some people only last for few hours, some others (like me) can last for months. I don't other better way than repeat the same steps.
We'll wait for the result. And please write the result in a new comment, it is easier to spot. If you make a video about it, you can share it here. Thanks friend 🙂
its worked for me .. but now i have 2 lines from screen.. but it worked enough for to get files off of it... hair dryer worked did it for 2 min and pressed down.. still working.. but like i said.. screen messed up..
I'm not technician so I don't know how to test the IC. For the temperature, you can search on the comment in this video, some other people already mention the temperature that works for them.
Thanks, @@gadogamix ^^ Here is my results : - Using micro-heatgun on CPU, good way, the phone turn on and full acces But... butbutbut, i must place the sim inside, so, turn off, and... green screen of death again Re-heating with the micro-heatgun, and... one correct boot and... freeze in menus (gasp !) So, i'll use my micro-oven, with this method, i will be sure the heat will go everywhere (i think not only the CPU is mad :P ) The main goal is to keep my datas in the inside-flash memory (contacts and GPS points in priority), so next good stard, i'll not touch even if sim is out :P Even if the phone is completly fix, i'll consider it as dead (Its new function, camera or for peices ;) ) and i think a Trekker-X4 will be my new machine ^^ So, to be continued ;)
I can't answer for sure. Some people able to revive their phone only using hair dryer, some others work by using iron, some with heat gun. If you use hot air station, I suggest set at 360 degree, low air flow, and try for 5 seconds only. If it still fail, try longer time, but for safety reason, do not exceed 10 seconds. The solder will melt at approximately 20 seconds.
I think that is a different problem friend. I think it won't work using this method, but you may try it if you feel nothing to loose. Before that, make sure the battery is properly charged before try anything, sometimes the problem is just the battery.
Well I just tried this. I had no Thermal tape, so ended up cutting sheets of copper in the shape of the cover. Put one inside the silver cover, then a square piece on top of that in the square hole, then another big sheet in the shape of the entire cover. I used a small(very small) piece of double sided tape to keep the pieces from moving. Then I had another weird issue. WHen I put all the screws back in, the phone wouldn't function. WHen I left the 3 screws in the main chip area off, the phone works. Not sure for how long it's gonna hold up. This is a beautiful phone, too bad it has these issues. Will never buy another LG.
I did this now my v10 keeps freezing and restarting. Boots back into system repeatedly works for a few minutes and sometimes for hours. The phone is not over heating... Could this be a software issue? I have no audio on the loud speaker and the test codes are not working. Model H900 running Android 6.0 At&T
Your phone (for example the screen) will feel hotter because the heat from CPU will transferred to other phone parts. However, the CPU temperature will be cooler. It will help a little but don't expect great difference.
Does lg g5 have the same problem as bootloop and fix it like lg v10 ... i want to buy lg g5 but i'm afraid of this problem .. and the likelihood of it happening is bigger lg g5 or lg v10
Any smartphone from any brand and type might experience bootlooping because of various cause, but for LG G5, I think there is no common issue (massive issue) with the bootloop. So I think you don't have to worry about bootloop issue on G5.
G5 is good but ive heard some sensor issue between the battery and phone detachment all the time, try xiaomi a1 or g6 for smooth experience or maybe a v30
I bought an lg g7 and downloaded an untrusted app. The next morning the boot loop started. The phone never felt like it was overheating...i always thought it was the unknown app.
I have lg v10. It doesnt turn on. ,i try to reheat the cpu and emmc then i try to on then it boots up. But the problem is after 20-40 minutes of using it shutsdown again and never turn on. Then i reheat again for the second time then turns on. What is the problem of this?
The problem is as I mention in the video. It might because of bad solder. To really fix it permanently, I think we need to reballing the CPU and eMMC, but I bet 95% service center can't do reballing CPU. Only a few highly skilled electrician can do reballing phone CPU on their own.
@@gadogamix It's actually ram chip and cpu sitting on top of one another. Ram chip is easier to desolder and reball than cpu which has many more connections. Just reballing ram chip can fis many bootloop issues.
Because some other people said that I should put music on my video 😅 Maybe you can silent the video and read subtitle only. There's a chance you don't understand my words anyway (because of my accent) lol 😁
My LG G4 did bootloop and I try to fix it by some ways but it fails then it turns off and doesn't turn on again but when I connect charger to it it charges battery It is a bootloop? Or a problem with power ic and bootloop together
Are you already try to turn on the phone while connected to charger? Maybe the battery is too low to start your phone, try to charge it first for around 30 minutes, then try to turn it on again.
yes same here issued to my wife's G4..the bootloop starts when she using data for internet and she always experience since then..but i bought a new battery (please bought genuine or a high quality replacement battery) and the bootloop problem gone!
Hey bro i had up my mobile vereion to marshmallow but its hang when i open cant even work for 5 sec can u tell me how i can make its version to lollipop again pls answer
I never try to flash any firmware in this phone so I'm sorry I don't know how to do it. But one thing for sure, it's a different problem than shown in this video. Yours is a software problem, so you can't fix it with method in this video. Maybe you can try to find an answer through this forum: forum.xda-developers.com/lg-v10
my lg g3 keep restarting ! i replace the battery and now the phone stuck on lg logo or boot screen for 2 to 3 minutes then automatically get restarted by itself ! does this is a software issue or hardware ! should i try to repair it or buying a new phone ? and thanks
Try to flash the firmware first. I hope it's only a software issue. If you have spare time and want to learn something, try to repair it first of course. Buy a new phone after you try to fix it and failed. However, if money it's not a problem for you, then I think buying a new phone it's better choice, LG G3 is pretty old right now and you can get better phone with quite affordable price nowadays. You can use your precious time to do other things than fixing your phone. So, it's your call
It depends on how bad the "damage". Some people only last less than a day, mine work ok for several months then it dies for another cause and I haven't try to resurrect it again.
This is a miss-concept - heating will not fix the bootloop but will slow it down. It will eventually come back, sooner or later. Installing a heatsink can prevent bootlop and not fix it.
If you experience bootloop issue on Nexus 5, I think it's only a software issue and you don't need to do this. Just try to reflash the firmware (software).
I'm sorry I don't open a service shop and I don't have a courage to do it on other people phones. The reason why I brave enough to do it on my own phone is because I'm ready for the worst case scenario and thankfully it works on my case.
