Hi XDA,
This morning I was just browsing Reddit when my phone suddenly shut down. When I tried to restart it I found that it was stuck in a bootloop.
I can only seem to get into download mode. Hard reset just doesn't seem to be working. Maybe I'm doing it wrong, maybe it's broken, I'm not sure. I was running the low effort root, and hadn't modified anything recently. Using the 2014 flash tool just gives me a "Connection to server failed. Try again in a moment" error.
Does anyone have any idea how I can fix it?
Edit:
THE ONLY KNOWN FIX IS TO RMA AND THERE DOES NOT SEEM TO BE A WAY TO RECOVER YOUR DATA
For some more information, the issue appears to be purely hardware based, and based on this thread seems to have primarily occured in the last months. Our phones randomly died during regular usage, then most users reported that rebooting it showed the "optimizing apps" thing (I personally did not see this) and then it rebooted again and went into a bootloop. Reinstalling the software often succeeds but doesn't actually fix anything, as your phone will just start looping again (still worth a try though, maybe you have some other unfortunate issue?). I myself and multiple users have tried the following things (text stolen from @dentralp because he wrote it up in such a good way):
Attempted Fixes:
1) Tried using LG bridge
-it says its updating to marshmallow (succeeds)
-then sits at LG boot screen without looping
2) Flashtool 2014 - Europe OPEN H81510D.kdz
-said that it couldn't connect to server
-clicked ok
-clicked retry
-says S/W update in progress
-stopped due to an error
-This is on my main PC, had issues with Flashtool before, will check on my laptop and feed back
-Fails on 9%
3) LGUP
-Only see's my device when I enter download mode
-Says my device is unknown so won't do anything with it
-Restarted Computer
-Wants a .tot not .kdz, contrary to the guide posted - out my depth, whats the difference between a kdz and a tot?
-Click on upgrade
-Chose Europe OPEN H81510D.kdz
-Close and reopen LGUP
-Making sure Refurbish is chosen (kdz should still be active file)
-Click Start
-80% Reboots, Reboots, reboots, reboots...
-100% "Click here to continue" on computer
-Reboot
-Bootloop
4) Longshot
-now I assume that I'm back on lp, moving back to step 2 Flashtool 2014
-Connection to server failed
-ignored
-seconds later it starts flashing
-Bootloop
5) LGUP
-Same as 3 above, but with MM H81520a_00.kdz
-Complete
-Bootloop
-repeated to go back to Europe OPEN H81510D.kdz
edit 26-1-2016
LG finally recognized the issue. They state that the problem is a loose connector. Article here: http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/
As far as I can tell, the issue is not restricted to certain phones, but primarily phones with serial 505xxxxxxxxxxx appear to be victim to this.
UPDATE: PEOPLE ARE CLAIMING THERE IS A WAY TO SAVE YOUR DATA
People are claiming that you can save your phone and recover your data by disabling the Big core. This means disabling everything that makes your phone fast. It may be a good way to recover your data if it's critical, but I would not recommend it as a real permanent fix, since it does make your phone a lot slower (a phone has 4 little cores and 4 big cores, the little ones are very energy efficient but slow, and the big cores are fast but not efficient). I don't have a clue whether this voids your warranty or not, and I've not seen many people confirm that it's working either, but it's worth a try! More information on the comment by gabriel713281 here and in the reddit thread here.

Hey there! You could go back to stock and fully wipe your phone using this method. Should work.
If the problem still remains I'd believe it's a hardware related problem. Hit thanks if it worked for you

When you get the ''connection to server failed'' error, just wait. it actually flashes but for some reason you get that error.
Hey, same thing happened to me. Went to my carrier the day after because I have warranty there. It ended up in them replacing the circuit board, now my phone wasn't rooted but it was in a bootloop and it just wouldn't start. We may not have the same problem but it could be so.

How long would I have to wait? After how long would I have known that it did actually fail? Or should I just leave it for a while and guess? If I remember correctly it actually reset the installing percentage as well, but don't quote me on that quite yet (I'll try again overnight or tomorrow morning).
Same issue today. Anyone got any idea what's going on?
Everyone with bootloop please write down model, operator and more importantly the initial three digits of their serial number (or production date from "Lg phone from" app in play store)

H815EU - unlocked bootloader / TWRP / Root
Last Update: 10/03/2015 - END OF THE SAGA
Solution 1 (Clean Software): RMA to LG or place of purchase
Solution 2 (Modified Software - within 6 months - UK): Return to retailer
Solution 3 (Modified Software - UK): Return to LG
Solution 4 (Modified Software - after 6 months): Find some paper to weigh down
Solution 5 (General): Don't buy LG's Hardware - quality control is questionable at best
The Journey
Although some people have reported getting some functionality back, no such luck for myself and majority of others.
What I didn't try
-Flashing MM20b - any method
-Flashing MM20c - any method
in fact, not even checked that they exists (no phone, lg has it!)
Don't think it was about when I was trying to recover (?) - I also highly doubt that flashing these will help you

Agent "Do you know its gone to the out of warranty repair centre.."
Me "Yes, I was told that it was so busy that they had to but I would get same quality repair"
I am hoping this isn't because of an unlocked bootloader, especially with the issue being duff hardware. Although this hasn't even been mentioned so far.... Starting to worry now. My house is full of LG electronics but I might not be using them again... !

Been bouncing back to carrier all day re the consumer rights act in England and the EU directive. They seem to think as a retailer that they have no responsibility.
Which is a UK Consumer champion with extended rights, it discusses the Consumer Rights Act at that link.

The Solutions
Solution 2
After 3 months saying the same thing and not leaving them alone, raising complaints about there complaints handling, contacting the Citezins advice, contacting which and reminding my carrier that;
the Sale of Goods Act 1979 (amended) protects me in this case OUTSIDE manufacturer warranty and that you are not only liable but have a legal responsibility due to the goods being of unsatisfactory quality and unfit for purpose.
Click to expand...
Click to collapse
My carrier eventually offered me a replacement phone, a Samsung Galaxy S6 Edge.
Solution 3
It seems that if you refuse to let them bully you and you remind them of the text on THEIR OWN website;
Once your phone is unlocked, it will no longer be covered by LG warranty.
As we cannot guarantee the proper operation of our hardware with custom software, we are not able to maintain the full scope of warranty for your device after you have unlocked the bootloader.
Because of that we have a responsibility to let you know that defects which may result from, or were caused by custom device-software may not be covered by LG warranty.
Click to expand...
Click to collapse
That they eventually offer to fix your phone;
Ok, here goes.
1) SBE suck major ass - don't even try to talk to them
2) NEVER stop emailing, if they say the case is closed, open a new one while copying in your old one (both to the same cic email, but nevermind it harasses them)
3) Remember, YOU ARE in the right, articulate it.
4) If you unlocked with their bootloader, you did so by the terms on their website. When doing so it DID NOT warn you that you would lose warranty for pre existing hardware faults, only that failure due to SOFTWARE may break warranty. With this your warranty is in fact 100% in tact and as warranty is a legal intent they are obliged to fix your phone. If you had been warned that warranty would IN FACT be broken, even for unrelated issues, you would never have unlocked the bootloader. The FACT remains that LG is not acting upon ITS OWN guidance, this is a PRE EXISTING issue and they MUST fix or replace. - I have NO legal experience, but I know companies will try to fob you off to make you back down. If you are in the right, keep at them, bring in more people to the mix, make life AS HARD as possible for them.
5) Word it better than I did in my emails below, I was a little bit annoyed writing them and they were often drafted on a Lumia 930
6) This is the end of a back and forth and what I personally believe turned the tide;
These emails are from the email thread, therefore read them the BOTTOM ONE FIRST
Me,
After lengthy discussions with our upper management team and senior technician we have decided to repair the boot loop issue on your device as a gesture of goodwill. Please note that this offer is for the boot loop issue only and you handset will not carry any further warranty with LG after the repair is complete.
If you wish to accept this offer please reply with the date (Mon-Fri) and the UK address (we currently have [address] on your file) that you would like the phone collecting from and I would be happy to arrange this for you.
Kind regards

No you haven’t, you entirely ignored my email again. Please explain the excerpts from your website, I will include the full quote;
“Once your phone is unlocked, it will no longer be covered by LG warranty.

Your quote is from a title, the contents and description of the terms are then spoken about in the section below it. You are referencing my reference cylindrically and it only enforces my point.
If you can’t answer the simple questions I would like you to put me on to someone who can.
Also, define developer. My bsc hons is in computing and I have worked with Linux since redhat. I fully understand hardware and software and for one effects the other which is why i am so upset about the crap hardware you made.

Dear Mr ME,
In answer to your question regarding the official LG website which allowed you to unlock your device, it clearly states at the top of the page “"Once your phone is unlocked, it will no longer be covered by LG warranty". As you can see this statement is very clear and there are no stipulations or exemptions to this rule. Just to clarify when we say “it will no longer be covered by LG warranty" this means for any and all faults including faults that are unrelated to the bootloader being unlocked.
It also clearly states at the top of the page "Please be advised that this feature is intended for developers only" therefore if you are not a developer you have ignored a clear warning which is there for your own protection.
I hope I have clearly explained our position to you and the matter can now be closed. I understand that you are disappointed with our decision and am genuinely sorry that we have not been able to come to a more mutually agreeable conclusion.
Kind regards

If these are indeed wrong on therefore misleading they need removing from YOUR website.
As you can see, I followed a process provided by LG. Any issue that arose was not in relation to this and therefore by the wording of your own website, your own process, my warranty is IN FACT still in tact.

Whilst I do appreciate your comments and the disappointment caused by our decision I feel I have explained the reasons behind our decision at length on several occasions and as such I am not able to offer you any further assistance.
Please note that we at LG take all complaints very seriously and also accept that mistakes will be made and that we will occasionally fall below our service standards.

You should chose your words more wisely.
"unauthorised alterations "
The alterations were not unauthorised, in fact, they were enabled by LGE and was only possible due to LGE emailing me with an unlocked bootloader to flash.
http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS
"As we cannot guarantee the proper operation of our hardware with custom software, we are not able to maintain the full scope of warranty for your device after you have unlocked the bootloader.
Because of that we have a responsibility to let you know that defects which may result from, or were caused by custom device-software may not be covered by LG warranty."
THIS WAS NOT A DEFECT THAT RESULTED FROM CUSTOM DEVICE SOFTWARE.
Wording - MAY NOT BE COVERED BY LG WARRANTY.
This clearly leaves open that some warranty would be honoured, like catastrophic failure in the manufacture process. This clearly suggested that my hardware warranty is in fact in tact.
YOU provided me with a way to unlock my phone
YOU provided me with the software to do so
YOU provided the disclaimer leaving open the question about warranty
"LG will not be responsible for the damages caused by any custom software being flashed to your phone."
Custom software DID NOT cause damage to my phone
IF YOUR DISCLAIMER HAD STATED OUT RIGHT THAT AN UNLOCKED BOOTLOADER WOULD FULLY VOID WARRANTY I WOULDNT HAVE DONE IT. AS IT HAPPENS, NOTHING RELATED TO THE UNLOCK BROKE MY PHONE. YOUR MANUFACTURING DID.
Please read your OWN disclaimers, I 100% find YOU at fault for this.
It is only reasonable that you fix my phone - based on;

Very nice post and that sounds logical. I think that the update would be the issue? I did have updates turned off though. I would like to add that I did also manage to get in hard reset mode or whatever that is called, but it just gave a black screen for a minute, then the LG logo, then the android installation icon thing, then went back to a bootloop.
Edit: I live in Holland, so the update would be rolled out in all of Europe probably?
Model: LG VS986LD
Carrier: Verizon
First three of serial: 506
I have flashed the correct KDZ multiple times and it has processed correctly in both LGUP & Flashtool 2014, but after still bootloops. I have done a factory reset from recovery and issue still occurs. Original Bootloop occur out of no where, no recent (5ish days) changes were made.
Hey, This is a BIG problem.
In my country (Thailand), sales model is H818P Dual-sim.
but Something wrong.
almost H818P with s/n 505xxxxxxxxxxx GOT THIS BOOTLOOP in DAILY!! since October after V10f firmware update.
(other s/n get this too. but very fewer than 505xxxxxxxx and most of all bootloop was used G4 for 3-6 month)
It's not software problem, it's a HARDWARE problem. Can't flash KDZ. still BOOTLOOP
Until today, It's about 2-300 user in Thailand ever get bootloop and almost of them is normal user not advance user. They only update via OTA no flash tool, no root, and no any modify. use as normal daily life. camera, social, call, game, even in sleep time. This booloop can be found anytime.
However, LGE Thailand had release 2 announcements about this in this month. but nothing. They only told user can get free mainboard replacement. FOR WHAT??? We have waruntee for 18 months.
IF LG DOESN'T DO SOMETHING BETTER THAN WAIT FOR BOOTLOOP AND GIVE A REPLACEMENT. MAY BE NEXT PHONE OF LG FANBOY IN THAILANG WILL NOT A "LG" BRAND EVEN LG SERVICE IS A BEST SERVICE IN THAILAND.
Sorry for my ENG.
This is a common occurance with G4. In Korea, MM update was pulled by LG for a while b/c it was causing HARDWARE failure! ONLY FIX was to switch out the board. The Korean forums were full of people complaining of this issue. Most common was surfing the net would cause the phone to reboot, then boot loop. In Korea, you can go to a service center, show them your phone, and the board will be replaced in less than an hour. Other common problems are screen ghosting, screen burn in, touch screen lagging...ect. People seems to have accepted the fact that if a G4 malfunctions, the most likey fix will be switching out the board. Luckly my G4 has been working fine since the day one, but I haven't updated to MM. I never update to a new OS when it first comes out. I've had my bad experiences with bugs and incompatible apps and what not whenever a new OS comes out. I think of them as somewhere between alpha and beta. never mind the code change that blocks some mods.
Sorry, I digress. Other people have reported similar symptoms, even if they didn't update to MM. They also say, the launch day released version of the phone ususally has this problem.

Personally I would first delete spotify then reboot see if it fixes it,I personally don't think its the app spotify but worth a try. I would then also backup my data and try a factory reset. If that also does not work consider re flashing a new stock rom.

Nope it may remove the app but not root and service will be able to tell if it's rooted..Best way is to flash a stock kdz to get rid of any traces of it.

Hi, sorry to hijack the thread but my LG G3 d855 is exactly the same. on 29th December i noticed that the wifi wasn't connected to my home network, so did a reboot and still the same. I spent an hour or 2 googling this to find i wasn't the only one. Most had suggested a factory data reset, however said that this doesn't always work. I tried that and still the same so rang my network provider who passed me through to LG UK. It was booked in for a repair and collected on the 5th Jan. I got the phone back on the 26th Jan, and it took me less than 10 minutes to get the same wifi not connecting issue again. On the repair note it states they have changed the ic/pa/filter and updated the software to v20l (although I'm sure i was on later than that anyway). I rang LG again and it was collected the next day. I received the handset on tuesday, and the note this time said software updated, phone tested. I put the battery in, turned the phone on and within a minute found that the wifi would not turn on at all. I also noticed that the build version was V20h, which is a downgrade from the version that was on the phone when i sent it back to them.
I have rang LG again, and was told that they would look at it, but that i might need a new phone. When i questioned the new phone statement and asked why i needed to buyt a new phone, the woman didnt answer me. Anyway, the phone is getting collected today, and i really dont hold out much hope that it will be repaired. I have mailed LG direct to complain about this but i am at the point where i might move away altogether from LG. I am stuck until June waiting for my contract to expire, but am so frustrated with LG and their repair service as they have had my phone over a month now and havent fixed it.
This phone (g3) have bad quality components....my last lg....back to Samsung....I want my S5 again or a new S7 or note 4. Fantastics super amoled displays, great conections, all works. I'm tired of suffering...kkk

Yea Ive been a month without WiFi on it and I've taken it to 2 phone repair shops and its been said to be a motherboard problem and lg would have a big fee to fix it. I'm going to get a new phone soon because this problem is happening a lot right now with lgs

Well, update so far is they have "repaired" the handset and its on its way back to me so will get it on monday. I was going to bet a guy at work that it wouldnt be repaired but he wouldnt take the bet. if its still not fixed i think i need to go down the replacement route. I have tried to be polite about this, but the fact that they have ignored 3 emails from me trying to raise a complaint, numerous tweets and facebook messages is making me feel like LG are not a company that can be trusted. I realise that I am a tiny insignificant stone on the bottom of their shoe and am meaningless in the grand scheme of things, but i've never dealt with a company that simply ignores you....
I will update on monday when i turn the phone on
So as a follow up, I got the phone back on Monday and so far it is working fine, WiFi is connecting with no problems. The fix that has been reported is replacing the mainboard. 1 niggle now though is that there is now a hiss in the headphones that comes and goes which wasn't there when i sent the phone in for the million repair attempts. I cant be bothered to go through the hassle of reporting it and sending it off for repair so I'm just going to live with it (its not too bad, just annoying when the music is quiet or paused). I only have a couple of months before I can upgrade, and had thought about a G4 or G5 but after the past 2 months i don't think i'll bother.

so sorry for late reply, didnt know you had asked a question. Mine was done under warranty (apparently LG have a 2 year warranty with Three) so mine was fixed under that. I would guess that it would of been about 100 quid though for the work that they did, if not more. It took them far too many attempts to fix it though, which has left me with a bitter taste towards LG, so not sure whether to get the G5 next, the G4 or move onto a different make altogether

Hi all, ok tonight/this morning at work while on my break i went to do my usual thing of having food and watching a tv show via cartoon hd about 2mins in and my phone switched off.....now i thought it was dead so plugged in the charger but no led light, or screen on to say its charging.....i did a bit of googling and find out about the bootloop thingy buuuuut mines not looping, its swtiching on to the LG logo [i did the bootloader unlocker thingy etc so it says tha in the top corner] then it goes off.......i also get pulsing blue led lights too.....if i press, hold the power button after i get nothing, i have to take the battery out and then its rinse and repeat
Hi,
Same thing happened to me today. I was taking a shot and it switched off and same scenario.It seems that we had encountered an bootloader brick in which our device enters in some special bootloader mode in which when you connect it to the computer in the device manager it shows up as Qhsusb_bulk. I read the whole internet and there is a similar brick with G3 the guys were able to fix it. Even there is a tutorial on how to do this which I think is applicable to our device. I was able to install the required drivers and etc. but there is one big problem - I followed the guide and came into one serious problem - we need a special mbn file so we can recover our device and the sad thing is nobody on the internet doesn't have it still. There are many people like us who got selfbricked G4 and cannot fix it without this file. Please if somebody can help us please share the file so we can fix our devices. THANK YOU !

ive seen lots about the bootloop issue, but the thing is mine isnt doing a loop [i have to take the battery out/ pop it it back in, to switch it on then after 10-20 seconds on the LOGO it turns off

on G2 you get security boot error phone is detected as QHUSb_BULK. on G2 the fix was to enter download mode. in G2 vol up then plug usb.
using TOT method and flash tools . flash stock firmware fixed my soft brick.

I have the issue. I don't do anything special but my phone reboot and stuck on lg logo. But now my phone doesn't want to boot. Sometimes he detect when I'm trying to charge it but often not. Yesterday I boot on download mode and recovery but today it's impossible... I think I have some hardware issue ? Or software with the bootloader...
I don't know how to fix that without access to download/recovery mode :crying:
Same here. Sometimes it boots into recovery/download but most of the times it doesn't. It's a hardware problem I think as LG officially confirmed that there were problems during the building proccess of the first G4 series. I don't want to sound bad but soon or later all phones built before october last year will get into bootloop. I was hoping it won't happen to me - I'm very light user with only light standart apps with no games and other heavy stuff, so the problem wasn't caused by overheating by heavy multitasking. Anyway it happened and I'm pretty sure it's harware related but if somebody can provide the tot and mbn files I will be more than happy to try the g2/g3 unbrick method. The main problem is that these files are not available for h815. I found on other forum tot files for other variants than h815 So if somebody have the tot filesfor h815 please share so we can try to unbrick our G4. Thanks!
same thing heppened to my g4 this week. i called lg last night and they agreed to repair it. i'd just gave them a call.
I sent mine for repair today. I hope they will agree to repare it even that it's with unlocked bootloader and with rooted custom rom !!! What you think ? Will I have problems with them because of that ?
Happened with my phone as well. It was rooted so i was hella scared if they didn't accept my phone. But soon they told me phone's motherboard has gone bad and will be replaced. Got my phone with a brand new motherboard after a couple of hours.
P.s. all your data will be gone

So the same problem just happened to my lg H815 with unlocked bootloader, am really f***ed without my phone, gonna call LG UK tomorrow, anything in particular I should say? also looking for solutions I saw many people are starting to have this issue now too - any official comments from LG?
P.S. if you have an LG G4 you should start backing up all your data now
This literally just happened in the last 15 minutes to me as well. Random reboot right after I woke up the phone and now stuck on the LG splash screen. Light user here, never did anything with the phone that would have heavily stressed it physically or computing-wise, so I also concur it's an inevitability for earlier runs of G4 phones.
Luckily, I backed up everything through TWRP last Thursday by chance because I was updating Xposed to the latest version and swapping to a faster 128GB microSDXC. At worst, I might have lost a handful of unimportant text messages.
Not worth the time to try to figure out any cheap fixes myself, I just got done submitting a repair request to LG.
I ordered LG G4 H815 and I hope to not see any kind of these issues

I was regularly using my G4, it was on cyanogenmod 13 nightlys for a good while now and i updated it every week or so. (haven't updated it in at least 10 days this time but it shouldn't be an issue) Suddenly the device turned itself off and went into a bootloop. I found a couple of weird things with this bootloop.
1. it wont boot into the device ever. it just shows the LG logo for a few seconds, goes black for a second then repeat.
2. I cant enter recovery mode, i used the button combination and go to the "factory reset" screen, selected 'yes' twice and i should have been sent to TWRP, which i have installed. But instead it just took a while on the yes/no screen and then blacked out, and rebooted back into the loop.
3. Sometimes it goes a bit further in the loop, and gets a little into the boot animation i have. I found that letting it run a longer time gets me a higher chance to see my little boot animation.
ive heard there was a hardware issue with LG G4's that were bought back in September of 2015 but i bought mine in June last year so i don't think that's the issue.
i didn't backup my phone for a long time so i'd love to get my files back! (otherwise I'm getting a new phone in a couple of days but i still need it until then)
Any and all help will be greatly appreciated! thanks!
What is your phone's S/N?

I have the exact same problem, my phone died like this yesterday. The colder the phone is the longer it runs without rebooting so that might be a hint for you, although i have never seen it boot up completely. Maybe you can put it in the freezer or something like that. I was lucky because i just switched to cm13 and make backups of all my data the day before.

People in the US and some European countries (ie Germany) didn't have a problem getting it fixed under warranty despite unlocked bootloader, root or even custom roms (because it's a known hardware issue unrelated to software).
Others did.
Try, you got nothing lose..
As for a fix, there is a process that involves disabling CPU cores, has worked for some. Check http://forum.xda-developers.com/showthread.php?p=67149552

I bought the phone as an international phone from a phone store. I dont have an LG center here and if i try to ask the store to fix it under warrently i'll probably get turned down because the bootloader is unlocked (you can clearly see that in the LG screen)
I will try talking to them but with ~20 days of warranty remaining i doubt my success chances are high
I brought mine from a phone store unlocked too (Carphone Warehouse in the UK) and it also had an unlocked bootloader running Cm13.
When it started suffering the bootloop problem they repaired it no questions asked. Worth a go.
Mine done that but wouldn't turn on after I took battery out I didn't try asking on here but no luck so I took it to insurance and I ended up with the g5 as they had no g4 repaired and ready to come back to me in 24 hours lol. Carphone warehouse ? big thanks to them now to wait for g5 to get some good stuff ... ?

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.

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
