I bricked my LG G3 D855 - G3 Q&A, Help & Troubleshooting

Hey guys,
So I was screwing around with some Cyanogenmod ROMs on my LG G3, but after installing a snapshot cm12, the Phone won't boot up anymore.
I can't access TWRP, download mode, recovery mode, I can press all the buttons but nothing happens, the battery is 100% when I installed CM so that's not the problem.
I think it is bricked, but maybe you guys can help me, first time this happened to me.
Thanks in advance,
Noah van der Woude

Thanks for responding, if the warranty doesn't replace my phone I'll try this, I think it's too tricky trying that.

Hard bricked. Jig? Please help.

I hard bricked my v500. Just black (dont ask why, its too stupid). Could I implement a jig? How? Thanks for your help.
What you mean with black ? Black screen ?
And what was the last you doing.
Are you tried to restore the FW with the LG mobile Tool.

Ok. I rooted stock, then downloaded lg update. This resulted in a boot loop to cwm. Then - big mistake - I installed a cwm boot fix for a lg handy from cwm. This surely screwed up boot entry. After that it is black no matter what I try.

lol. yea you pretty much F'd it up.
Hmm try LG Recovery Program.

Yeah, f***. I should have followed the rules of survival. You are in a dangerous situation, stay calm, do not rush. Now think twice, no fast solution. Which is the logical course of action? Too late. I was downloading recovery from LG Mobile support tool 1,5GB, thought, lets see if I can have a faster solution...
What is LG Recovery Program?
I think the only thing helping would be a jig.
Could something like this archieved?
http://forum.cyanogenmod.com/topic/71825-hard-brick-to-hell-and-back-guide-to-recovery/
Or I try this one here:
http://www.fonefunshop.co.uk/cable_picker/96296_LG_3-in-1_Micro_USB_Unlock_and_Flash_Cable.html
Its really hard to cope with my stupidity in the moment...
My gut instinct is that a jig could get you into download mode but I have no idea what pins to use.

I tried the jig from the link above. Nothing. It is dead alright. Gonna send it back for repair.

HELP needed! G4 Bootloop!!

Hello guys!
It all started today in the morning when I opened Instagram application on my G4 (H815 model) and suddenly the phone froze. After 15 or 20 seconds it tried to reboot itself but it went straight into bootloop. It's not acctually a bootloop. It tries to go past loading screen and reboots another time and after that all I can see is LG logo.
I tried to enter recovery mode. No success. I tried updating/flashing KDZ file with LG Flash Tool and I got error everytime saying there was not enough information....
Last thing I tried was to boot into download mode. It shows Firmware Update screen but I don't thing ADB is working. I tried command adb devices and it found nothing.
I'm so desperate now as I need phone tomorrow. I hope it's not hard-bricked. Do any of you have idea what to do?
Any help apprechiated
TIA

lots of people report bottloops theres a thread and i said about 80% suffers from it.. its a hardware problem from lg .
thers the flash kdz to disable big core ,phone will be slow but usable.. and some have reported that warranty was denied and some had luck and phone was fixed give it a try..
because the first phone are suppose to be more likely to suffer from it.. so to know if its old earlier phone. or new one . that soeant suppose to happen anymore but it still does..

Thanks for the info. I checked serial number on the box and it says 507. I know a lot of 505 has this issue.
Do you have a link to that thread to disable main cores? I can still sell working phone rather than bricked
And I'm so pissed now because I didn't do anything wrong. Damn LG! Life's not good anymore!!
Is there possibility to flash KDZ with other program than LG flash tool? I can't get it working, it always says it couldn't find right information...

Yes it's LG issue, but if you had not unlocked the bootloader , you would still have warranty. They will be fix this without problem

well only time will tell most will do .its just a matter of time.. since they are new and the ones getting bootloops are older.. so they say it takes about 8-9 months to show.. will need to wait and see. in 10 months from manufacturing date.
you cant tell wich one will but, LG says they fixed the issue in new phones..

Yes, I tried everything. I've sent LG G4 for repair with unlocked bootloader, they replaced it without problems. I was without phone for 16 days though. It's working now, but I have some WiFi issues (slow download speeds)

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..

Its been unlocked for ages and running the cyanogen rom, this is what is now stuck but was running fine. lg website doesnt have the programme any more, will hunt for it. so this will work even though phone doesnt boot?

Need help after hard brick

My phone died while surfing and clicking a link (link was ok I checked on a notebook). It seemed to restart but ended with the LG logo - and after that ended with a black screen. Then I tried every combination to boot again (Volume down+Start button to get into recovery, Vol- + USB cable to get into download mode, took out the accu) but nothing happenend. Just dead. Do you have any idea to let my phone start again? Thanks for any help!
Either the ilapo bootloop. Or if its a hrd brick only fix is octoplus box with jtag support. Were u flashing anything or did it just reboot into a bootloop

What is "ilapo"? And sorry, but I don't know octopus box, too. I wasn't flashing anything, just surfing on a website. For a short moment I saw the LG Logo, after that it was black...
Hrdware failure mother board is bad. Called infinite loop auto power off. Its a defect. Call lg. They may fix it under extended waranty
After I have a read a lot about this specific problem in this forum, I think it's the same with my phone. I will send it back hoping it will be repaired.

Any idea if LG will fix your phone? I also have a hard brick on my BRAND NEW G4.
I tried TK's root method on my H811 but my version is 10d and seems like it does not
work with his version of the root image (10h).

I hope they will. But ath the same time I'm looking for another phone, too. Because I don't know whether the fixed phone will survive for a long time. Obviously LG shouldn't be the first choice at the moment.

There are even refurbed phones that lg has fixxed ilapoing too. From what i understand no g4 is safe.
Seems like you had an old G4. What is your serial number? Only digits matter. Mine is 602 and so far noone got bootloop on 602, if your is 500-510 ur very likely to get bootloop. You can still turn on your phone with modifying hardware but best way is just to give it back on warranty

Did the same, bought a zenfone 2 yesterday. So far really happy, great for the price. I don't like the bloatware so I unlocked, rooted and installed CM13. Very easy and smooth process. Working great.

Bootloop, soft or hard?

Hi,
I've got H815 stuck on LG logo. I've tried flashing stock fw, the I've tried the LG Bridge way, all of them completed but still stuck. Then I've tried the hard reset but no luck. Is this hardware issue then?

I've tried that already. Flashing goes well, but then it's still stuck on LG logo. Another thing, when I leave the phone without the battery for night, then in the morning it boots up up to optimizing apps, blue led flashes but then goes back bootloop. Some people here recommend lgup with different dll files and particular fw but I don't know if there's a point.
Yea I unbricked my bootlooped H815T with thiskdz give it a try..
I got this phone second hand and the guy said he was trying to downgrade fw, after which the bootloop happened. Is it possible that it's just the anti-rollback and not the faulty motherboard? How to make sure?
My phone is in the freezer now and we'll see how it goes...

I've just tried something that definitely prooves that's hardware issue. I've disabled big cores using that guide and phone works now. It's just single core though. You can make images to run on 4 cores but it's only temporary solution and I'm afraid the phone may die at any time. I think I'm gonna do the return but the guy is not really happy to do that.
Maybe try to unlock the bootloader and flash twrp. It's what I would do.
Best of luck
It is unlocked. I'm just gonna return the phone. Guy sold it as having a software issue, but disabling big cores proved it's an infamous LG ilapo. It can run on 4 cores, there are guides how to do it, but you can never be sure when it dies completely. Thanks for help anyway.
