Hi all,
Just got news of the marshmallow being available to my LG G4 (H815). I was aware of the update having been rolled out to Poland and Korea before so I thought it was a safe bet.
I plugged in my phone, started the LG Bridge software which prompted me with the update. I went on and downloaded it, which happened without any issues.
However, when the process was over and my phone restarted, it went through the usual "app optimization" window and after that started boot-looping. I have the initial audio cue from LG playing every few minutes, with the same "app optimization" for 12 apps (when the first time it was around 90).
I initially left it for a while (5-10min) before i started losing patience. I removed the battery but that didn't change anything.
I initiated the Recovery mode, but it prompted me with a "factory reset" question, which I didn't feel like doing before having tried anything else.
My phone is not rooted and was running Android 5.1, the LG variant. I never fiddled with this phone.
Has anyone else experienced issues updating? Do you have any suggestions on what I can do to recover my data? Because for me, that's mostly what I'm concerned of.
Thanks!
Edit: In addition, I'm facing a new problem... while boot-looping, my phone is actually draining more energy from the battery than my charger can provide (yet, it's a 1,8A @ 5V).
It's now down to 10%, which I've been able to verify by removing the battery thus shutting down the phone, putting the battery back inside, and plugging the phone in while being off. However, this automatically turns on the phone, so it briefly displays the battery charging animation before booting... My phone was at 100% during the Marshmallow update.
Which S/N (serial number on your box) do you have? 505 and 506 are known for this issues..

yes it can be a issue of the 505.. Not to scare you or anybody else (there are people here that are crying and closing threads because i talk things like this.) But 505 is a known issue that some of the motherboards have defects. I hope you can fix it for yourself or call the cheap manufacturer LG..

Are you aware of this being a reason for replacement units to be issued? I didn't buy it through LG directly but through amazon, so I'll get in touch with them, but just wanted to know if you've had any experience or know of anything regarding this. And thanks for letting me know.

Np chief. They will fix your phone, just say it is in a bootloop after LG's official update. Call Amazon or LG itself to fixe this problem. (you mentioned you didnt root anything etc so you are good to go boss).

I figured, they would just try to restore my device and send it back to me, so I tried it and it worked. I'm still disapointed for two reasons:
- I still lost valuable data which I can't retrieve any more
- I'm still stuck with my device which could very well be prone to other issues in the future (any future update ?)
There are issues with this phone because i had 3 Rma's because of motherboard and dead pixels. My wife has also dead pixel and has version 506. Just use your phone, Marshmallow update is out so maybe they changed something in the system to stabilize the motherboard.

I finally ran into the bootloop problem that is common with early G4's (if you have a serial number that starts with 505, you're basically gonna be screwed at some point). Since it's a hardware issue that LG acknowledges, I sent it back to the factory under warranty, waited for two weeks using my old backup phone, and finally received it back today.
Ready for the fun part? They had repaired something that wasn't broken (kind of like surgery on the wrong body part) and had not touched the bootloop issue! They fixed "No power with cable" by replacing the flash memory. This was never an issue. The frustrating thing is that they didn't even restart the phone to find out if it had been fixed, because if they had it would have gone right back into the bootloop. Arg!
The G4 is now back on route to LG. I said they should give me a new phone, but customer service said they only do that if it cannot be repaired. I'll keep my fingers crossed that they go to the trouble to turn on the phone after "repair" this time.
Thanks for letting me rant!
I have currently my 2nd G4 that has run into this issue. This one has serial number starting with 506, so I guess it might stem a little further into production also. This is driving me nuts, I could not send my phone to LG because of how long it takes so had Verizon send me one and of course I run into the same exact issue with the bootloops. Last time I was able to still flash kdz's, this time won't even go past the LG boot screen. Really wish I could wipe my data at least.
I can attest to LG's incompetence. On March 2nd I sent in my G4 because it was bootlooping. Sent it in no problem, and after about a week I received my G4 back with the problem "fixed" by flashing the memory. Well guess what, it wasn't fixed. As soon as I turned it on, it started to bootloop again. I called LG and they arranged another RMA. Sent it back again, and about a week and a half later, I had my G4 back. This time they "fixed" it by replacing a capacitor. Guess what! Still not fixed. It still continued to bootloop. Called LG extremely angry and filed a complaint. LG arranged another RMA. At this point I had been without my phone for over 20 days. Finally, LG fixed it properly by replacing the motherboard. Now its fixed and it only took them over a month to figure it out.
While I applaud their easy RMA process, whoever the idiots are actually doing the repair are just that.. idiots. Its as if they don't even turn the phone on and ensure it fully boots up before they claim its fixed and ship it back. Whats worse for me is my phone was rooted on VS986B. Got the phone back on Marshmallow 24C and it took the update to 25a overnight. Now I'm stuck with no way of rooting.....
When you get your phone back from LG, chances are it will be on 24C. If you plan on rooting, do so quickly and downgrade.

When they finally replaced the motherboard, did the physical serial number on the phone change?

No, that's the same. The board was replaced, but the plastic piece that holds that battery, which is on top of the board, was not replaced.
Happy to report that all is well after the second repair. Came back with 6.0, but I downgraded to 5.1, rooted, and have just about everything working again (can't get Exposed to work, but I'm sure I'll figure it out eventually). Nothing like spending 3+ weeks on a 2011 Droid Bionic to make me appreciate my G4!
Would one of you care to explain how you contacted LG to set up the repair. I have filled out the online form twice and have never heard a word. Thanks.

Im not sure if you are in the U.S., but here's their support phone number 800 243-0000. They are usually pretty easy to deal with over the phone.
I am still kicking myself that I didn't downgrade as soon as I got my phone back. I hate not having root anymore.

Droid bionic.. I wish! I originally dug up my old Galaxy Nexus, but the battery life was so bad that I swapped it out for my son's old Droid Razr. Of course, I had to safestrap it and put a custom ROM on there because I have a LG G Watch R and android wear was not compatible with the factory software on the Razr. It was a pretty horrible experience overall. I'm glad I have my G4 back, but I really miss root.
You can still downgrade to 5.1 and root. Mine was on the latest version when it came from the factory and I didn't have any problems with the process.
Same thing happened to me. It took 3 RMA's in a row and about 60 days until they finally fixed it. They scratched it, too. OP, I highly recommend you start documenting everything. LG CS will also tell you escalating will get you nowhere; but with persistence you can get a hold of someone. You can only go up to a supervisor, and that's it. LG has specifically designed their CS (including their facebook and twitter) to contain and ignore you.
In less than 1 calendar year i am on my 3rd phone.. Figuring the 1st phone was a flop... serial numbers since my 1st phone are 511 and 505. So yeah.. im debating at what a ticking timebomb i havenow. The 3rd one came w/ MM installed but I downgraded to LL to keep root. Im sure it goes w/o saying that I'll not buy an LG phone ever again.. and this was my 1st one. They could offer to upgrade me to a G5, but honestly there are NO guarantees this sort of thing will happen again. You break trust you pay the price, look at Samsung w/ the no MicroSD card fiasco.
LG just accepted my 15 month old G4 for warranty repair
Even though my phone is 15 months old, LG has accepted it under warranty repair. When requesting repair I wrote that it was the bootloop issue but their repair confirmation states the issue is "No Power with Cable". I hope they fix the correct issue! BTW, my serial number began with 511
The US warranty is 18 months, so LG didn't do you any favors. I have three of these POS phones to get warranty repaired and hope they fix them correctly the first time.

I just got mine back today june 1st 2017, Sent G4 for bootloops 1st time a week ago. No power / Mainboard was replaced. it was purchased november 2015 and Serial number is 511 which is right after the supposed bad batch. I got the phone back in the same great condition it left. The repair guy reported phone condition has minor scratches when it doesn't, Not sure why he would report that. So far its working great, like a new phone. I can only hope this board has been redesigned to not fail under a year and a half, but thats just wishful thinking. Everything was completely free even though phone was like 5months+ after its warranty. Even though costumer service on phone sounded like she was doped out on crack and ignoring all my questions, it was still ez to do and I got it back fast. The IEMI number or whatever was also changed and they put a new sticker over top the old one under the battery. I tried checking the number on that website and it doesn't even have it registered so i can only hope its brand new.
Got a couple of VS986s back from bootloop warranty repair. Mainboards supposedly repaired, but IMEI stayed the same and nothing on label under battery changed . I recall other people mentioned changes to label information.
Last week a representative told me the current warranty on the G4 for this issue is 27 months from date of manufacture or 24 months from date of purchase.
Mine has S/N 508. It started bootlooping while I was pooping (browsing Facebook on Chrome browser) on June 5.
I attempted the hot-air rework station fix 5 times (for processor on mainboard), and that worked on the 2nd, 3rd, and 4th tries. Each time the phone worked for up to ~4 hours. On the 5th try the phone no longer booted or even showed the LG logo.
It's en-route to LG right now. I opted to ship it without battery or back cover (my back cover has a wireless charging tag).
Using my old Samsung Galaxy S3 running an AOSP-variant on 4.4.2. Actually isn't a bad phone.
My old LG G2's touchscreen no longer responds to touches on roughly 50% of the screen... can't even unlock it via pattern lock any more.
Thinking LG won't be the next new phone I buy...
Well, my G4 is on its way back to me after LG's warranty repair. Turn-around time at the LG service facility was ONE (1) DAY!! So that was super fast. Should get it tomorrow or the day after. Contemplating putting it back up for sale or trade-in though... it's basically gonna be a virgin device that will require root, xposed, restoring apps/messages/call log/etc., then adjusting everything else to my liking. Would be a shame to do all that work and then the bootlooping problem happens again.
Got mine April 1st. Worked great until May 9th. In the morning it hung and went into a boot loop. After 7 or so reboots (at various stages of boot cycle) it came back. A few hours later it did it again. This time 4 or 5 times and went dead. I tried battery pull, SD card/SIM card pull, and even swapped to my fully charged spare battery. It will not power on.
Called Sprint and they offered to sell me a used phone or fix it for a fee. Called LG. LG said they would take care of it but I would have to send in the phone for repairs and it would be about a 2 week turn around.
It's too bad because I really do like the phone but It'll take a while to regain my confidence in it...coupled with the locked boot loader...I don't know. It has the potential to be a great phone but LG may be shooting themselves in the foot.
Yeah I've had the same issue. For some reason sometimes it would get itself stuck in a boot loop. I would wonder like what the heck is going on... My camera also stopped working functionally and I couldn't make phone calls. I tried factory resetting it and issues were still there. I had to send in my phone which was super dumb... Not only is my phone not working but I have to be without it for like two weeks.
This used to happen with G3... I went back to Samsung. But now i got G5 and i havent had any problems.

my boot loops all happened in the same area, my wife's work. First time when I dropped her off on my way to work and again when I picked her up on the way home. I've noticed before there's a spot where I get really bad reception in the driveway of work and the phone switches to 3G or worse. Both loops started when that occurred. It may have just been a coincidence...and I've certainly been other places with various degrees of worse reception...I was at a datacenter inside a faraday cage just the week before and didn't have any problems.
Since these phones can't be rooted yet I haven't done anything that any consumer wouldn't be able to do. I DID disable some services and installed adguard, but anyone can do that and none of it requires elevated privilege or voids the phone's warranty.
The status on the LG web site is now "repair in progress".
Fortunately I use GV so I can answer my calls and texts from any phone and just went back to my G3 while thr G5 is out for repairs.
Interestingly, when I called LG they didn't even ask me for details. They immediately said "send it back and we'll fix it". Either they have really good no-hassle customer service (they might, this is my first experience with LG customer service so I have no frame of reference) or this is more common than they let on and they know about it.
phone is on the way back. the fault on the repair order is listed as "power management IC".
Let's see what others with this problem get....if you sent your phone to LG for repairs the diagnosed problem will be listed on the email from LG notifying you the phone has been fixed. Looks like the PMIC problem was present in the G4 as well.
I wonder if there was a manufacturing defect in the first batch.

How long did it take LG to fix your phone once they received it? How long was it actually at LG before they shipped it back to you?
11 days

Nothin to do with first batch g4s even repair still doing it. They said any g4 aft sept 15 was good. Nope even more are looping everyday.
I haven't experienced this issue. I have had the screen ghosting issue, and my volume-down button just stopped working altogether a month ago. I've debated sending it in for repair, but I have been able to manage with the on screen controls. I really cannot go two weeks with no phone in my line of work.

Anyone know about the bootloop issue that affects our phones and lg is offering full refund long as have the receipt. The part that causes the bootloop is not available. Anyone know about this or experience this issue? http://www.androidpolice.com/2016/1...unds-for-some-malfunctioning-nexus-5x-phones/ …
Yes, I got the bootloop last week. Sent my phone in to LG and am awaiting response. Will post back if I receive the email listed in your article.
Side note. I had the exact same issue with my previous LG G4 and was actually successful with getting the device working by 'cooking' the motherboard. Now that definitely voids any warranty and is not foolproof, but if people don't want to lose their device for a payout, it's something they could try. (Again AT THEIR OWN RISK!)
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
