Hi there,
I've been exactly there with my H815. I have tried numerous solutions, but to no avail. On your reddit post I saw that you tried the recovery key combination and ended up in download mode again? Did this happen, after you pressed a button? With my phone, when the LG factory reset screen appeared and I confirmed twice, a long time nothing happened. After a couple of minutes the Android recovery (not TWRP) screen appeared. Maybe you'll have a chance to get your phone recognized via adb sideload or sth. Or start fastboot mode. Maybe you can reflash TWRP? But if you are facing the same problems as me, it probably won't help you.
For me, I ended up sending my phone to LG, despite the fact that the warranty was void. They changed the mainboard and never said anything about repair fees and apparently the phone is on it's way back to me as I write. I hope it arrives tomorrow and I can let you know.
Hang in there! :fingers-crossed:

My warranty is over ( 2 Years ) Do you think I could try ?? (Bootloader unlocked/ Custom rom and recovery have been installed)
But I can access to the LG recovery if you mean the one with Restore factory with double Yes ? But when I press Yes my phone freeze like 15 seconds and reboot in download mode...

I cannot give you any guarantees, as I am not associated with any LG support haha. Technically, I am still on warranty, but as I also unlocked the bootloader, installed Custom ROMs etc... the warranty would be void anyway.
I got a reply from LG support that i should send it to their repair shop (some shop in Germany) and they would reply with an estimate of the repair costs. Now, all I got is the tracking number, the phone's on its way home and they did not charge me at all (as of yet). So you could be lucky, but you very well may not be.
I'd say, take your chances and contact LG support, send it in. If they want to charge you a huge amount of money, they can still send it back to you unrepaired and you might be able to fix it yourself. In any case, I wish you the best of luck!

the thing is after you have flashed TWRP you HAVE to boot directly to TWRP afterwards. otherwise it gets overwritten.
You can also setup SALT and depending on what your current firmware is you can flash TWRP with SALT too.
For that IRC is much better though http://webchat.freenode.net/?channels=carbonfusion-user

Hi,
A belated little update. My phone has found its way back to me and is working perfectly again. The main board had some dysfunction, it was exchanged.
LG didn't charge me a dime, so I can't complain. Flashed LOS 14.1 just now and everything is running smoothly. Hope you had some luck with your phone as well?
Cheers
Ok I tried everything with salt, with the motherboard ! Last thing I can do is to contact the support ... Waiting their answer and i'll tell you the feedback

XDA,
I just got into a bootloop while on the Facebook App and I pressed the home button. I read that it happens to random people, but I want to make sure that I am safe.
I rooted roughly 5 months ago, when I got this phone and I've never had an issue.
What are my options? If I call VZ/LG will they accept my rooted phone? Or can I fix this bootloop? Will using this method http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848 help me ?
Thank you,

EDIT: My phone booted up, the apps were optimizing, but then it just rebooted back to the LG screen and now it's stuck there.

http://forum.xda-developers.com/g4/help/lg-g4-stuck-bootloop-t3268734
I had full bootloops apart from when MM was installed, it just sat there on the LG logo. Could be that your on MM with the issue?
I have tried LG Bridge, Flash Tool and LG Up with various different roms, both LP and MM nothing worked.
Mine is also Rooted, with the bootloader unlocked. LG UK have been sat with my phone for over a month - hopefully I will find out soon if they have fixed it using the warranty - but even if they do, mine is with LGUK not LGUS ...
Think what I am trying to say is, try all the methods and if it doesnt work send it for RMA with your fingers crossed :/

Just so I understand you, I basically have to RMA my phone? All the other options seem like they resulted in a bootloop. And RMA I'm assuming you mean using warranty?
And I'm not on MM.
Just out of curiosity, would the fact that I rooted my phone disqualify me for using mywarranty?
I guess you rooted with injected system.img. If you can go to download mode you could write the original system.img back, so then you are not rooted. Or you could write a KDZ file in LGUP.

As far as I'm aware, simply restoring an original unrooted system.img backup will still show "Modified" in the download mode status, once it's been rooted. The only way to clear that status is by flashing the KDZ. (You can still keep your personal data with that option though.)

Based on what I've read in the main bootloop thread, the bootloop issue is a hardware problem that requires the phone motherboard to be replaced so I don't think they will be able to detect the root during the RMA process:
...
I have received confirmation from LG that series from May, June, July and August are afflicted by this issue and that the revision number doesn't matter. They also said that it is not necessary that all phones in these series will fail, but that under certain circumstances (not disclosed to me) they will start producing the bootloop issue which is h/w bound.
...
Update: It seems not all bootloops are due to deffective motherboard as on some phones they were able to detect the root and refused the repair under warranty.
So maybe for some G4's stuck in bootloop there might be a solution to be soft repaired.
I saw this in another thread, can you try this?:
...
Using DL mode (device off -> press and hold volume up while(!) connecting to PC) and LGUP you should be able to push any KDZ on your device and get out of the boot loop.
...
I don't have the bootloop problem so I can't test it but it might.
What's the build date of your G4 (between May-August 2015?)? What are the 1st 3 digits of your phone's S/N?
If you root any phone you automatically void your warranty. There's no exception to this and I actually understand why they do that because most people don't need to be rooting their phones lol but if u find a KDZ you're str8, use the flashtool and you'll never get into a permanent bootloop and you can use your warranty. But most likely something you modified or something another app was doing caused the bootloop not a hardware issue. Also it'd probably the last thing you ever even thought that caused it lol

Have you tried a hard factory reset? Usually helps
Well, my GF's G4 started bootlooping a few days ago, the local store she bought it from doesn't honor the warrenty and says it may be something we did. I didn't like hearing that and decided to take legal action.
In the meanwhile, she asked if the data can be restored, I started playing with it and reading online. The phone bootlooped anytime I took the battery out and reinserted it, then go off. I decided to put it in the freezer after reading about many successful attempts to boot the device. The first time I put it in a plastic bag for 5-10 minutes (when I took it out it had humidity on it which I wiped), it turned on! and went into Android app optimization and we were thrilled, It went off after 2 minutes so I decided to put it in again for 30-40 minutes in a sealed plastic bag (as many recommended), when I took it out it didn't turn on at all no matter how many tries I tried switching batteries, connecting to the charger etc. (it had humidity on it again when taken out of the freezer).
From then on, the phone won't turn on at all, I put it in a bag of rice in get rid of humidity/water but that didn't help and the device won't bootloop at all.
Now, I have no case as it doesn't bootloop and the store can claim there's damage not governed by warrenty, I can't claim it bootloops as it is a brick.
I'm worried the water caused corrosion which totally cancels her warrenty.
Hope someone can help me fix this out, cant believe I hope it will bootloop again.
Thanks.
What version of G4 have you ? H815 ? or other ?
you can try to flash official firmware with LG UP with .kdz file or if you have another G4 with .tot file
You must have computer with drivers installed and LG UP installed
Watch tutorial
It's H815, SN: 505***
How can I flash it if its not booting at all? Can you elaborate on how flashing the official kdz will help? The phone is not rooted.
Is there a way to restore the bootloop? I want to claim my warrenty but without the bootloop scenario Im screwd.

1. volume up and connect to pc
2. flash the "core disable" kdz/tot (whatever it is)
3. it should boot but it won´t be as fast as i has been

To be honest with you pal i very much doubt you'll get it back working as the serial is a 505 which means it's included in the bad batch of faulty motherboards on the phone and its that which is causing the bootlooping , you need to tell the place where you got it that the hardware has failed out of your control if they don't help try contacting LG directly you could be lucky....

When I did the following steps, I was able to get back into the phone with all my apps and internal data right where it was. It only fixed the corrupt system files. It seemed to work like startup recovery on Windows. But as a warning, I've only done this once so cannot guarantee you the same.
i) Make sure you have the LG Drivers installed from here: http://oceanhost.eu/e4h2px4e0hkd/LGM..._4.0.4.exe.htm
ii) Download the LG Bridge software from here: http://www.lg.com/us/support/product...reinstall-apps
iii) Remove the battery and reinsert it so the device it is fully off.
iv) While holding the up volume button, insert your USB cable.
v) You should enter download mode. Go to the Software Update tab of the LG Bridge. It will say connecting and then should say your device is up to date. Click on the recovery text on the bottom right and then follow the instructions. The software will download the system image for you and this is roughly 1.6GB so make sure your firewall doesn't block this connection.
I was lucky and this didn't remove any of my data.
If you have problems with LG Bridge detecting your device:
i) Make sure you have the drivers installed and are using a reliable cable and USB port.
ii) Open up device manager and look for your phone. It should be named [...... COM#].
iii) Right click and go to the ports tab and click advanced. Select COM41. This seemed to work for me.

you could do 2 things.. one download KDZ use LGUP flash it and see if it was software related or something went wrong at flash.. if it keeps doing it then it has the bootloop issue.. and need to be sent back for repair....can you provide your first 3 digits of your serial number...?

yes it is its pretty easy... . file is big though... download kdz for you variant.. what android you are using.? MM or were you on stock LP.?
well i think since your phone is from 2015 august. that bootloop was supposed to be fixed by then. but newer phone are still getting hit by the bootloop.. but be aware unlocking the bootloader voids warranty.. some been lucky that phone were repaired some were denied repair..

Going to give this a whirl now mate, thanks.
Hi,
I've searched over xda and google before but haven't found anything relevant so I've decided to post my own problem.
My G4 freezed unexpectedly while listening to music, I had to remove the battery to put it off.
But it never passed the LG logo again.
So, i've been stucked on this LG logo, looking for an answer and found about this hardware issue but I'm not certain to get the same error.
It's not a bootloop (even if I sometimes got stuck in bootloop while trying everything to revive my phone), I have been able to get to the download mode and TWRP (which I don't have anymore because I went back to stock using LGUP and LG bridge), even though I hardly get to the download mode now (I sometimes manage to do it though). I've also managed to save my data when I've managed to enter TWRP (plug in, remove battery, push volume down + power while putting battery in) which, people with hardware issue haven't, as far as I know.
I've tried everything I could and wouldn't even be able to describe it all.
Do you guys know how I could be sure if it's hardware or software related ?
Last try: update via Lg Bridge, succeed but still stuck on LG screen.
Thanks a lot !
Flash a lollipop kdz via LGUP, then try the ILAPO (works only with lollipop, no marshmellow) metod, there is a thread on xda.
There is a video on youtube too

I gave a look on what you've suggested, but is that going to let me use the phone or only backup ?
From what I understood (and I might be wrong), this only allows to backup because the phone would be worthless...

You'll be abble to use the phone, but it would be slower duo to the fact that with ILAPO you disable the "2 more powerfull" cpu cores... this metod let only 1 core active from the other 4, if you want to use the other two you have to gain root permissions and install an .apk to reactive the other 3. It's a litle triky but better than nothing I guess ��
PS: if you dont want to deal with all this bulls**it send it to LG
Same problem
This morning my Lg G4 also got stuck in boot Lg screen. Did you manage to fix your issue or got the data backup ?
sometimes flashing stock LP firmware fix it.. sometimes you must send it back to LG for repair..

I managed to backup, it's a weird trick and you need to have TWRP installed I guess:
- Remove the battery
- Plug your phone (I used my laptop but I'm guessing it also work directly from the charger)
- Push volume down + power
- Insert battery holding those buttons
I managed to enter TWRP and backup with this.
It didn't work at first, I had to try it several times.
I also read you have to keep holding volume down + power until the phone reboot itself once, and then you get access to TWRP but I tried so many times differently I don't remember which one worked best. Anyway, it worked for me that way.
I didn't fix the issue and I sent it to LG... I'm so frustrated, it's been 10 years I'm into this stuff and I always managed to fix everything
Hi guys,
So my G4 just came back from LG, they replaced the motherboard and that's it... A bit disappointed to not having been able to fix it myself but at least, it worked.
I didn't have to pay anything since it was a hardware defect, LG took care of it.
Thanks for those who tried to help, I hope this post would be useful for some with the same issue.

I'm having this same issue out of the blue. Is your serial number one of the infamous "before 509" ones? I'm on TMo with the H811, so it may not be similar at all....but I'm at my wits end. I've never had a spontaneous boot loop happen to me before now. It was always something I'd done.

Indeed, my serial number was 505 something.

Interesting... Especially since mine was a 509 or something. I guess they missed some units. Oh well, I just JUMP'ed early with my TMo plan to the G5. That was my second G4 after a similar issue 13 days into owning the first one back in November. Having your phone spontaneously die is quite a fun way to spend your anniversary -____-. I wasn't about to give that model a 3rd try. Thanks for replying.
So my mom had an LG G3 D850 from at&t. was totally fine, then she updated whatever she had to 6.0 and it started bootlooping. Tried the LG Flash tool with a tot stock firmware. Went through the whole process got the blue screen with the red 3, it restarted, kept bootlooping. Tried it again but then it got stuck on 5% for like 4 hours, unplugged it and now no matter what i do i cant get into download mode. It shows the LG screen then goes straight to firmware update (even if i dont hold vol up) and it says 910K Bxx QEM (the xx changes) I was able to get into recovery mode, recovered it. same thing. Im losing my mind a little bit here so any advice, or pointing me to a tutorial would be greatly appreciated. Ive looked all over the internet and cant find anything helpful apparently the qualcomm thing where you short the motherboard doesnt work for this phone either?

Qualcmomm method you are describing is just to bring your phone into download mode. I have done this to my brother's g3. You have to flash using LG flashtool using different settings and then hard reset your phone. If it doesn't solve your problem.try to replace battery and then use custom rom.
tried that

no matter what settings i set LG flash tool to it doesnt recognize the phone. and no matter what i do the phone jumps to the firmware update screen, it skips the download mode screen. I have two batteries and ive repeatedly switched them back and forth :/ even after reseting the phone with factory reset it goes back go the firmware update screen

totally forgot to switch to com41, did everything exactly like that. got to the red 3, restarted it, and it still bootloops. i guess ill try a custom rom cause this stock one isnt working.
apparently cant do custom roms either, I got it to boot the the set up screen for 5seconds befores it crashed so i guess im throwing it away cause im sick of looking at it.

Try LG PC Suite go to option update error recovery it will download the stock rom flash it dont worry it will take some time so be patient also what happened is when ur g3 wasnt fully updated meaning it got stuck or turned off when updating
.hit like if its helps
