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

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

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.

So I went to attach a picture to an email (Outlook for Android) and my phone rebooted. It goes to the LG splash screen and just stays there for a long time. After a while, it flashes off and right back to the splash screen. I've tried pulling the batter and removing the SD card (just in case). Nothing is working.
I stopped by the Verizon store and they said I need to ship it back for replacement. Really don't want to be without my phone that long. Anyone know how to get it back up and going? I can put it in download mode if that helps.
Just checked a few sites and found a thread here. Seems to be a "not if but when" boot loop issue with the early G4's. My serial starts with 505 and that falls in the range of devices others are having an issue with. Great. This will be the third repair in less than a year.
You're gonna need to send it back to LG. They're very nice about it and will pay for the shipping. You'll be without your G4 for a couple weeks, but it will they will replace the circuit board. I just hope you have better luck than I initially did (see my thread about LG's incompetent repair in the General section). Good luck.
dumb question, where are you locating the serial number. I have checked the box and back of the phone. Nothing with S/N or anything that looks similar.
Box only has:
imei
sku
upc
sw ver
icc id
manuf. date
dhhs code,
sim sku

Just got the email that it has been shipped back. I'm guessing "Repair Results: Swap Board (Main/RF) : Others" means they swapped the circuit board. Fingers crossed it is actually working when it arrives.

I found it on the sticker on the back of the phone under the battery.
I was looking into buying a new phone, something with an unlockable bootloader and semi easy to root. I came across the G4 and it looked pretty promising. I was most likely going to buy it then I found this issue with the bootloops. It seems like a fairly common problem with the early models of the phone. I was wondering if I were to purchase a G4 now if it would still have the same problem or it has since been fixed. I couldn't find any recently updated threads on the issue so I thought I'd come over to xda.
Thanks!

It doesn't matter whether your model was European. It all matters when the device was manufactured. What was your serial number? 505xxxx?
My phone was producted in septemmber 2015 does my phone will have bootloop ?

theres a 95% possibility it will..
oct 2015 is suposeldy good. Sept 2015 and earlier are highly prone to loop.
And hardware revision 1.0 is bootloop prone and 1.1 is again supposedly good also. But as raptor said 7 or 8 months seems to be the magic number.
Ive actually moved on to a diffrent device and pit my g4 up for fancy ocasions lol. Lg k7 real low specs but unlockable bootloader.
So this will be my first and last lg phone

i dont understand.. why i have 601, but on HW. 1.0 ?? makes no sense.. unless they wanted to get rid of all the 1.0 MB.
Thats weird. Mines a 1.1. Dont know the serial num but its 10 2015 so mines suposedly the first line that were good.
---------- Post added at 01:33 PM ---------- Previous post was at 01:30 PM ----------
I can find a straigh answer where serial num is. If i go off dec num xxxxx508xxxxxxxxxx is the only 50 type number anywhere thats straight off my box and phone. Is that the proper way to read serial or is th 50 or 60 number somewhere else. Like i said im usind the dec as whole serial num

Welcome to the sinking boat. If your phone is still under warranty then go ahead and raise RMA with LG to have the motherboard replaced. The warranty is actually around 15 months. I bought mine from Amazon in Germany last July and my phone went into bootloop at the worst possible time when I had my flight in the morning and had holidays planned. Can you imagine how this messed up my plans... escalating this with LG to take responsibility but so far I'm only spending the phone for repair to one of LG approved repair centres in UK. I live in UK and European models should be fixed in the country you are in if there is repair centre.

i also have 505 s/n production date of may it still works like it did first day usually bootloop occurs after 9 to 10 months its already been an year n one month:good::good::fingers-crossed::fingers-crossed: i have H815 taiwanese model had a chat with one of LG technician today he says he hasnt yet seen this country's models to bootloop as of yet seen eur,sea and other carrier variants ...
See u guys say the serial is in your case 505 as the first 3 digits Every num on my box here it goes. Upc 528. Dec starts 528. Hex 357. Iccid 890. Rs. 171. These are the first 3 digits in every number on my phone Again how do u. determine the serial num.

Hopefully yours won't bootloop but somehow I wish that yours bootloop sooner than later before you run out of warranty. Also don't forget to back up your data constantly since when the bootloop hits you it usually hits you when you are the least prepared and when you need the phone the most....

Yes, if you want something similar to LG G4 go for the Moto X Pure, better specs, same price range ($200+ on Best Buy for the 32GB version) fully unlockable and possible fast updates from Google.
*** Of corse I meant S/N and not IMEI in post subject! ***
So, my new (bought end of May) LG G4 just died. No boot loop no nothing. It just won't turn on anymore.
Before dying it stopped charging at a random %, thought that was some random software issue, of course that wasn't.
Anyone else had same issue?

Hey there, 606 here too, bought at the same time. No issues whatsoever. Lets hope it it was just an isolate incident
BTW, did you try to take out the battery and put it back again?

It's not the beginning of your IMEI, that might be linked to device failures, it's your serial number. If your serial number would start with 606, your device would have been manufactured in June 2016.
Lookup your production date etc.: http://imeidata.net/warranty/lg?imei=<IMEI GOES HERE>

I'm pretty sure my S/N is 606. I'll check when I get home, maybe I'm wrong

yeah, tried everything and with a different battery too.
Yes, I really hope that's just bad luck...

It would help to know when yours was actually made as buying a 606 (June 2016 manufacturered) phone in May 2016 = 605 means you bought a phone made in the future.

Helio guys, I'm planning to buy a aecond-handed G4, but I've seen that there's a major issue with it, a bootloop problem caused by the motherboard.
My question is, Did LG repaired that problem on some new G4 models, I saw that phones starting serial number with 505 are the ones that will fail
Thank you
hi,
if you have a phone with serial 50x, then you need a new motherboard (phone) with 6xx

You have to ensure that the serial begins with 603 or higher
also ensure that you do not buy a phone with an already replaced mainboard! Means the phone should be produced in 2016

Thanks for your reply:good:
So, phones with serial starting 603 and higher doesn't have this problem?
The one I'm planning to buy is this, I asked the seller to send me a screenshot of hardware info.
After seeing it, should I ask him for a serial number photo?

this is very interesting! How do you know that from SN 603 there are no more bootloops? Is there a statement from LG?

1. let him pull out the battery and take a pic of the serial there (this is no guarantee though because if it was in repair the sticker could be replaced as well)
2. please consider to buy a h815 international(!) or h811 because only these both can be unlocked!

Just my personal experience and opinion. There are no guarantees or official statements anywhere.
experience means:
I own 2 h815 and both having serial 603 and both are in heavy usage because of development and they are still alive.
regarding the background of my opinion:
LG acknowledged the mainboard issue in January 2016 (http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/) and so we can assume that beginning from then it should be fixed for any newer devices then that date. 603 means March 2016 so I think that beginning from this charge it will be safe. again no guarantees nowhere.

he should get a tmobile h811.
well i can vouch for that too.
after readings lots of complains you can see the pattern that most 5xx failed. and keep failing. some are lucky thoug.
LG claims that from 511 upwards its fixed . but reports are different . only a few 601 and rare 603
it doesnt mean it wont theres no way to tell but chances will be low.
am running a 601.
I saw a poll somewhere (might have been here on xda) showing bootlloop data by SN and as expected most of the bootloops were on 5xx devices. But there were a few problems even on the newer devices.
It seems logical that refurbished units in the past 6 months or so should hold up. At that point LG had determined exactly what the problem was. However, I have read threads on folks who had their G4's replaced with refurbs multiple times. I just think it is a gamble when picking up a G4 because you never know if it will last, these things are like ticking time bombs. It reminds me of the RROD Xbox 360 problem a few years ago. Best bet is to get a warranty.
My personal experience was a G4 505 purchased on release from Verizon June 2015, bootlooped October 2016. Verizon replaced with refurb and SN 506 which has been running fine, no evidence of bootlooping.
