Hi. I recently bought a g4 without much research. Now i see that a lot of people complain about that bootloop problem. The good news is that it hasnt happened to me (yet atleast) but i kinda worry for it so i wanna ask some questions. Is there any way to prevent it from happening? If it happens, what can i do to repair my phone? When it happens, does it wipe all my stored data (phone contacts, photos etc) or everything is safe and the phone just refuses to get started? Is there any other info i should know about that issue? Thanks in advance
Hi. The problem is that it is likely to happen to every G4. It's bad, but true.
In fact, you should be lucky to not happen this to you.
There is probably no prevention against this. But after it happens to you, you can try to put the phone to the freezer for about 30 minutes to recover the most important stuff from your phone like photos, video, SMS, etc.
And because it is HW problem somewhere between motherboard and something else, you will lose your data because your motherboard will be changed as same as everything what's integrated on it.

If the bootloop happens then what should i do? Do i need to go my phone to a (tech) store to be fixed? And if it happens and i finally repair it, is it possible to happen AGAIN?
Yes, you need to go to a tech store and let them fix it. And as I read, it is possible to happen again. I have my motherboard changed just once and I hope it won't happen again, but it is possible.

Omg what a problematic phone.. Okay and i got 1 more question. Im ok with the 32gb internal storage of the phone, but im now considering buying a card (its called sd i think) to move my photos there. They will be safe there, right? If so, do all do the same thing or theres better and worse ones?
Yes, true. This phone is great anyway except these problems.
Dont worry to buy SD card, but be careful of its speed if you are recording FHD/4K video or if you are (like I do) listening FLAC music. If so, you will need SD like I have which is about 60/15 down/up stream. And if bootloop happens and you have your photos etc on the SD card, they will be safe, as you said.
Thank u my friend. Now this topic can be locked or whatever, i dont have any further questions for the moment atleast.
Just for the record: if your G4 does suffer from the bootloop at some point, there are no "local shops" that can fix the problem, it's something that only LG itself can resolve. The best you can hope for is registering the G4 with LG under your own name, picking a date of purchase like September 15 2016 or something (note that if that were the purchase date it would have factory warranty until September 15 2017), and if it does end up dying at some point before the warranty would expire (based on the date you entered as the date of purchase) then you might be able to get LG to replace the motherboard (at their expense including the shipping both ways) by contacting them through their online chat support service if and when it becomes necessary.
There has never been a conclusive answer as to why the G4 (and the other LG devices) suffers this problem but it's believed - note I'm saying it's believed and that's based on some sound principles of how and why phones can and do die - to be heat-related and also related to a manufacturing defect aka they used pretty crappy solder in the manufacturing process on the assembly lines.
The belief is that when the G4 and the other devices run very warm like when using 4K video recording or playing a game for an extended period of time or perhaps running device benchmarks in a loop for stress testing that the SoC (the Snapdragon 808) heats up enough to where the solder points holding it to the actual motherboard become softer and develop micro-fissures which are literally small breaks in the connections and after multiple such heat-up cool-down heat-back-up-again cycles that the small micro-fissures become larger and eventually they become large enough to prevent the proper flow of electricity aka electrons.
Think of pavement on roads. In the summertime that pavement heats up and it expands (literally) and then as night comes on it cools down and contracts, then the next day it heats up again and expands, then cools, over and over again - over a period of time that heating up expansion and cooling down cycling causes cracks in the pavement, and as vehicles drive over those cracks it'll cause chunks of the pavement to break off, more and more all the time which is how the classic pothole develops.
Same principle with the G4 and the other devices suffering from these bootloop issues (again that's the belief). Why LG let it happen for so long across multiple devices (some G3, a whole lotta G4, some G5, some V10, and even a V20 or two have been reported, and of course the Nexus 5x too) is beyond me but it's not relevant anymore. There's a class action lawsuit against LG (I'm part of it having owned several G4's that did bootloop and I currently have yet another G4 that's working fine so far) so maybe it'll get resolved at some point. LG has repaired all the G4's I've had issues with and I fully expect them to do it again with this F505S I currently have if it dies.
Anyway, that's some background on the issue. If the G4 you have dies, nobody is going to be able to repair it except LG so, go to LG's website (in your country) and then register it in your name (you'll need to create an account if you haven't got one already) and the use the info/IMEI to get it properly registered, say you bought it in a carrier store (unless it's an H815 then just you got it from LG direct), pick a date sometime in the latter part of 2016 as noted and see what happens.
Good luck...

A few users have reported a Blank Screen of Death, with myself included.
The problem being that the phone's display doesn't switch on when you wake up the device. At this time, Everything else will including the Digitizer and Capacitive buttons.
I have spoken with HTC service centers across Australia and NZ to come to the conclusion that this is a motherboard problem. The infamous flickering issue seems to be involved also, which ends up shorting out the video driver.
The issue isn't just limited to the screen not displaying anything either, there's also the possibility that the back light will cut out, and sometimes leading to corruption on the display.
This isn't just with some devices either, it seems like anyone that has had the screen flickering issue are at risk of this.
To give you an idea of how much it costs to fix this issue, I was quoted at $250 AUD for just the motherboard alone.
The best part is, HTC may also deny your warranty for unlocking your bootloader, as they have with me.
I'll be posting more information as it develops.
EDIT 29/07/12 :: I'm going to request a transcript of my last conversation with HTC but until then, they're denying that this is a problem and saying that it's the user's fault. How? We use our phones to much, or inappropriately.
It's becoming obvious that they're trying to avoid spending anymore money fixing these issues, and have decided just to move on and release a new One X model. (according to news sources.)
Also, Boobinator just posted a video of the One X's screen corrupting while it isn't stuck under the BSOD which you can see here and here
Just to recap.
When the initial issues were found with screen flickering and corruption on the display, we were told it was a software issue.
Many months later, I along with many of you are still experiencing it, even though it's not nearly as bad as it once was.
Now there are growing reports that One X's are starting to lose their displays, and the poly-carbonate weakening and bending the antenna pins. (You can find more information here)
This is something you should all be aware about when purchasing this phone.
Best of luck!

Update Bump
Maybe us in America can file a class action lawsuit? I'm no lawyer here but anyone with better understanding of American consumer laws chime in?
This is problem that occurs with normal usage of the phone.
Another day, another hardware issue. HTC is going down the drain, im hugely disappointed in the way they are handling this mess. Improper testing, too slow to fix problems or ignore/deny them. Bull**** games about unlocking and warranty and now they are already talking about releasing more phones. Its easier for them to move on to a new model than to do the right thing and do a complete recall. Is this a QC issue or a design flaw, with all the negative reports I'm thinking its the latter.
HTC better handle this properly, they need to stop development on all new products untill this is solved.
Sent from my HTC One X using xda app-developers app
Can u please send me details about the store that sells the motherboard ?
I have the same problem...and I need my phone fixed !
Thx
Is this the same flickering that happens in some ROMs when you rotate the phone?
Mine too
This just started happening to mine Nothing displayed on the screen, but it still responds to inputs. Even rebooting into fastboot, same problem. So everything is functioning except the display.
Have just handed it back to vodafone for repair, don't like my odds with the unlocked bootloader though :/
I had this issue on Viper or Android Revolution, but not on other ROMs. But I'm starting to get wifi issue, scratches, scratches on camera lins. I should buy S3, not this.
Sent from my HTC One X using XDA Premium HD app
sent it back because of flickering. I just hope they will fix the problem properly and change the motherboard.
Sent from my Legend using xda app-developers app
This happened to my Incredible S too if any one's interested.....
I'm not buying the HOX, I'm sorry. There's just too many different issues for too many people with this phone. It's an expensive top of the line phone, that does appear to be pretty shoddy put together. I don't care if it's under warranty and I have dumbass-insurance if I break it, but I can't send my phone inn all the time even if it's free. You shouldn't have to send it in at all.......
I presume now know we know why HTC is loosing money, market share and their stocks are going down....
This happened to me too, about a month ago, the phones been in repair since then(1 month, are you freaking kidding me HTC). I also unlocked the bootloader, lets see whether HTC charges me or not.
Also, I managed to get the display to work(somewhat) after shaking the device a bit. But even after that the display wont work properly, I even have 2 short videos of the screen acting weird when i got it to work. Here they are - Video 1 Video 2
Sorry for the ****ty quality, got it on my iphone. This was after I shook the device and the display magically started working. Even with the display working you can see it is really weird, even unresponsive at times.
So guys, there are a lot of places you can buy motherboards from, but they will charge you a lot more than what it's worth mainly because of the shortage within HTC.
I'm so sorry all of you are going through this, but i think we need to raise awareness of this issue. People are buying these phones without realizing there's a good chance they're going to have either bad WiFi antenna's or even a bad motherboard.
Send this to your friends, post it around, contact HTC.
Best of luck!
I am having this problem as well, as well as the WiFi antenna issue. The WiFi antenna somehow bent itself somehow, because after a while it was back to normal signal strength, so I didn't feel like sending the phone away for a month. But now with this screen issue it really is unusable, so it seems I don't have a choice anymore

Heat damage.
I doubt it's heat damage, i hardly played games on mine and it had that problem. I think the most i played was Triple Town, and that was it.
Also, wouldn't it be a massive problem if it was heat damage? That means the tegra 3 processor can't handle stress, and given that the phone inherently has heating issues, this just draws the conclusion that the Tegra 3 is bad news?
it may be a faulty soc
From what I've heard, it's been linked directly to the flickering screen problem. Which could mean that the first batch of One X's have all faulty Soc's? I mean, it's not uncommon for there to be manufacturing difficulties for the first few batches, but this is just absurd.

Not all of the first batch flickered. Stop exaggerating.
Once upon a time,about 8 months ago,there was the little newbie me,I that old E975(lgg) and decided he should get a new phone with all those "G4's" "S6's" etc,I wanted a phone with killer specs,and the best camera out there,so I decided to go with the g4,looked up prices online on his country. Pretty damn high,so i found that one shop that sold it for like 100$ less,no official warranty,unofficial warranty for 1 year,that seems fair,I bought it,the biggest mistake i ever made, the phone was so good,it worked like a charm,and god damn that camera was awesome,about 4 months ago i was sending a whatsapp when it just got stuck on that screen,m'kay i tried restarting,won't work,removed the battery and inserted an other one,boot to lg logo and then shut down,alright, i still got warranty. time to use it,went to the store,they said "we can't fix it",worst customer support EVER,ever since that I've been using that ****ty replacement phone,ewo,so today i was really bored and decided to look up the problem and noticed my s/n begins with "505" looked it up,apparently all the g4's with that s/n got stuck eventually,and the store knows that and since my warranty is unofficial I can't do ****,or can I? is there any way to get out of this with a functioning phone?help?
Temp Fix
Mine died yesterday. It's a hardware fault apparently and can't be fixed. You can, however, disable big cores and recover your data, but your phone will be really slow.
Here's the link:

i was just about to cook the phone and teared it apart,i saw the whole oven thing and i thought to myself "Why the hell not" and well it should work...if it will stay the same i'll use your tutorial and probably use the really slow G4 instead of my current 2012 Huawei

Phone doesn't work really slow, if you know what to do. My phone is working since I disabled the big cores what is about 2 weeks now, I'm even on a custom ROM. All you need to do is to root it and using 'Device Control Manager' (Kernel Adiutor doesn't work for me) change the frequency what will enable all 4 cores and with 4 there is no big difference in the performance really. I feel like it's more Qualcomms fail than LG's, cuz look G4 was first phone with Snapdragon 808 wasn't it? What if the first processors they made they sent to LG as they are all now in s/n's 505-509 and what if these are faulty? It actually would make sense, with 6 cores my phone didn't even turn on, with 4 it works as normal, it means there is 'something' wrong with the two faster cores..
It's LG's fault. They have admitted such. It's a faulty connection/motherboard.
UPDATE
i've baked the phone,it works for now,how can i make sure that it'll keep working?
Replace the motherboard.
but they don't sell them on my country,and it'll cost like 400$ with shipping,and nobody replaces mobo's here,so is there any way to make this one keep working?

I'm sorry, but unfortunately you dug your own grave with that one. You may have saved yourself $100, but caused yourself major issues in the long run sacrificing that warranty.
Honestly, there is apparently no way to ensure it'll keep working. A lot of users have reported their phone dying again after LG has fixed it. A motherboard replacement is the second best option with the first being a phone other than the G4.
Hello guys i've been seeing a lot of boot loop news and lg starting to refund people because they don't have spare parts : http://www.mobilechoiceuk.com/News/...offering-refunds-instead-of-replacements.aspx .
So should I be worried that my 5x will boot loop ? I've been using it for 2 months now on 7.0 september update .
just yesterday happened to mine!
Did you try to fix it or got it refunded under warranty ? Also rooted or stock with update ?
Hi, i guess that nobody could know that, but the problem seems to be the same as LG G4, LG V10, LG Flex 2 (all 2015 devices with almost the same motherboard that the Nexus 5x). You can search on the web "bootloop G4 reddit" "nexus 5x bootloop reddit" and you will find tons of reports, the majority of them (N5x) from last 3 months, and this holds the theory that is a welding issue on the CPU or sometimes on the EMMC chip (apparently LG did not weld very well that year...). The mentioned devices (included ours) seem to last from 9 to 14 months and finally the welding breaks. But now, we know it's strictly a HARDWARE issue NOT caused by 7.0 upgrade, irt's only a question of coincidence between the useful life of the weld and the launch of the 7.0 OTA.
So we all got very high possibilities that this occurs to our devices, eventually. I'm not sure that this is gonna happen to you, it really dependes of many many many factors (heavy usage, kernel profiles, temperature of your country/city/house/workplace, etc etc).
Maybe it never happens to you, but i know what you feel, is not very nice to feel that your phone could die in any moment. It was a low punch for me (i owned a G4 and it bootlooped twice) anyway i am going to sell my N5x due to this problem. Hope i help you with my point of view.
It is solder not weld.
Only Google/LG know how widespread the problem is on 5x.
My guess is it is far more than normally expected for phones but nowhere near as prevalent as posts on forums might make it seem.
So normally you might expect .01% of these types of solder problems. If the problem went up 100x to 1% and you sold 3m phones, that means 30,000 phones with the problem, whereas before you might only see 300.
30,000 people searching google and seeing other people posting about bootloop can start a panic.
If you actually had 10, 20, 30% of people with this problem you would have huge threads.
That's just my opinion.

If you said "It is solder not weld." for me, thanks i didn't know the correct word, english is not my native language (I only learn reading on forums), so i see that you know (or it seems) about solder problems. Look i had two LG G4 both of them die, but not just mine even a cousin had the same issue whit his G4, so i really want to know if you think that the 5x soldering problem is a similar case of high-end 2015 LG Phones G4/V10/FLEX2 (of that magnitude)? or if it's just a "paranoia", i mean we know that the bootlooping issue on this device exists but you would recommend me (i really like this phone) to keep it?
This issue got me really worried due to my bad experiencie with the G4. I just bought the N5x 1 month ago. thank you.
same question how to know if my phone will bootloop...i have my nexus 5x 5 week ago but i bay it not new i bay it used...i upgrade to android nougat no issus right now..ho to know if i will have a probleme in the future iam afraid now

I've been dealing with substandard solder since xbox RROD (red ring of death) where everyone was trying to get their xbox cpu reballed until microsoft admitted the problem.
As I mentioned, I'm sure the incident on 5x is much higher than normal phones, but that might still be a low % (even though it is a relatively high absolute # because of the # of phones that are sold)
I have no idea whether 5x is worse, better, or same as G4 problem. G4 seemed even higher, but could be because more phones were sold. Only LG knows for sure.
A lot of folks in US are finding that their credit card actually extends their warranty beyond manufacturers warranty and people will probably get their money back that way if all else fails.
Of course that doesn't help you if you are traveling and the phone dies. I end up using Google Fi as the service provider for this phone, so if that happened I could just shift all the calls and texts to another phone or tablet and keep going until I get a replacement phone, so I'm not super worried.
I regularly back up the stuff on my phone so the most I would lose is like 1 or 2 days of stuff, which I can deal with.
Personally I wouldn't be super worried this is going to happen to you, but be prepared with backups in case it does, but that is good practice for any phone, because it could always get stolen or drop and break.

Well from what I know if you don't have warranty paper then you can't get warranty by just showing the phone . Its not a 100% chance that it will boot loop I think , but if your not safe with it I suggest selling it working rather than looking for help when broken . Thats just my point of view .

Well I think i have the same point of view to sell the phone working rather that having a paper holder . At least for me its the most logical thing to do maybe the chance isn't high for it to happen but I am not secure with a tought that my phone could die + im a heavy user so i migh make it to the boot loop faster .

Hi all,
so here is my problem.
Day before yesterday i had a perfectly working LG g4 H815 model with s/n 511 running on firmware v20h, when i decided to root it and install some mods.
so i flashed TWRP, installed xposed and xtrememusic mod. the phone booted normally after installing these. i didn't install any modules under xposed. the phone worked perfectly for two days. however today morning it hanged while taking photo with the camera app. when restarting it got stuck at LG logo for long time. My brother(who doesn't have any technical knowledge) pulled out the battery and restarted. Again it got stuck at LG logo. thinking somthing wrong he again repeated this only to find that it didn't power on at all this time. No LG logo no notofication light nothing.
Tried charging it(although battery was aroung 60-70%), pressing power button removing the battery. still nothing. the phone is not at all powering up.
However when i connect it with USB cable with laptop, laptop makes sound of getting usb connection detected. i took it to a service centre.
the technical guy there told that IC may have been faulty. he told me that motherboard needs to be replaced. however unofficially he may try heating the IC to get it booting.
What should i do now? Is the IC really fried. had the rooting and installing mod caused it?
Please help.
PS- the phone is imported and cannot be sent back for warranty purpose.
I think you are experiencing the dreaded LG G4 bootloop. I don't think rooting or modding caused a software problem. It "may" have caused a hardware problem simply because it generated enough heat to loosen the IC that little bit that initiates the problems you are describing. I rooted and installed the stock image in Nov 2015. Two weeks ago the phone froze - restarted and then could not be booted. LG sent me a Fedex label and I sent it off. Ten days later I received the same phone back. I assume they replaced the mainboard.
You should contact LG directly. I saw a class action suit that was called off because it appeared that LG will fix this particular problem (failed mainboard) out of warranty. Anyone please correct me on this if I'm wrong.

I rooted and installed the stock image in Nov 2015. Two weeks ago the phone froze - restarted and then could not be booted. LG sent me a Fedex label and I sent it off. Ten days later I received the same phone back. I assume they replaced the mainboard.
You should contact LG directly. I saw a class action suit that was called off because it appeared that LG will fix this particular problem (failed mainboard) out of warranty. Anyone please correct me on this if I'm wrong.

Hi thanks for the help.
But isn't the dreaded bootloop is that where the phone is stuck at the LG logo. Mine isn't booting at all. And the bootloop problem is due to big cores or such and not due to ic?
Mine wouldn't start at all - it bootlooped once for about a split second - then it was dead
Same is the problem with me. Bootlooped twice and then its completely dead. I have tried contacting Lg UK. Lets see what they say.
Ok so i got a reply from LG and they suggested me some steps to take (which are obviously not useful as it is completely dead). however they have also told me that they are willing to help me and asked me about details of purchase etc and "whether it was rooted".
so what should i reply rooted or not? will they detect it as it is dead.

Sorry to be late on reply. I advise to not answer question whether phone was rooted. Here is my reasoning:
1. This problem is widely occuring - only a tiny percentage of people root their phones therefore question is irrelevant.
2. The problem is known to be that an IC becomes loose most likely due to heat - a better question would be - do you place the phone on a hot dashboard with GPS running while you are charging?

thanks for the reply (although late). i have already sent the phone to LG replying as no root. Lets hope they repair it without any problems.
second i didnt do anything of anysort like placing on hot dashboard or such. one day while opening the camera app it decided to just hang and later on die on me.
I hope you didn't think I was saying you might have done something that would overheat your phone such as my second example. I was trying to come up with an example reason the IC loosens. Even if you did that the phone should survive such conditions. Let's hope the replacement motherboards somehow do better. My guess is that the soldering job is fine, the problem is probably bad design that doesn't "vent" the heat from chip.

so what do you suggest after repair should i keep it or sell it? Lg g4 is no doubt the best phone when considering the value for money. no phone even twice in price comes close in camera and screen quality especially. but the unreliability of this phone has made me to consider selling it as soon as i get it back.
I'd keep it if your new board is high serial

Well my old board was also high serial, beginning with 511
I'm going to take my chances - it's a great phone until it bootloops. I'm going to avoid scenarios best I can that could result in the phone heating up inside. That would be charging only if absolutely necessary while in my ProClip dash mount if the car is hot, using backup battery after depletion instead of charging more often etc. Thinking back I rarely put the phone into heat inducing situations - normal use results in the IC becoming loose at the 1 year mark. If mine bootloops exactly a year from now and LG fixes it again I'm an LG fan. If they blow me off no more LG.
I really regret not paying it off early and taking the $15/month deal for an S7 Edge last month

Well lg did mention in my communication with them that this carries 2 year warranty.

I brought a g4 in the new year sale it has the serial of 611 i had a 601 few months back i returned it ran hot and laggy the 611 one is cool running and lag free so i think something changed
Whew boy has this been a troublesome phone. I purchased a new LG G4 off of Amazon January last year. It it had a warranty, it's long expired. I live in the US but mine is a SEA (Singapore) model H815. The serial number starts with 510, which I initially hoped meant it wouldn't bootloop, but it has become obvious even newer models still do it. Now mine has as well.
I tried the hairdryer trick but can't get it to stay on for more than a couple of minutes and bootloops again. Doesn't sound permanent anyways. Doesn't stay on long enough to do anything at all.
As expected, LG support has been no use. When I called (what I assume to be the US support line), they asked for the IMEI and immediately said it wasn't their problem due to the region and I would need to speak with the Amazon seller to get the contact for the right LG branch. I will try that if necessary, but I fully expect to not get anywhere.
To complicate matters, my G4 is rooted (I used the root injection method and still have a locked bootloader). Might make convincing LG to repair even more difficult, assuming I can get that far.
And on top of that, the original official LG battery that came with the phone was defective. It overheated and expanded, it pressed against the display, which now has extreme pink-purple tinted image retention. This fades but is ugly and annoying, though something I can live with (I found an app that seemed to help). I disposed of the original battery immediately (fire/explosion hazard) and replaced it with a TOTHL. Works great, but i'm concerned that it will be another roadblock in getting a repair.
So suffice to say, I have grievances and won't be using LG again (kind of missing my old first gen Galaxy S now). But it sucks to be stuck with an expensive paperweight and I am without a suitable replacement at the moment. Does anyone have any advice for how to approach this situation and possibly get it repaired? Or am I out of luck? I'm not sure whom to contact in this mess, and i'm also not sure if anything can be done given all the complicated factors (rooting, using a third party battery, display issues, it being an international SEA model etc). Any advice would be very appreciated.
