[Q] Help to unbrick my LG G3 - G3 Q&A, Help & Troubleshooting

Hello friendly devs,
So I messed up big time. I updated to 23C via the OTA and then discovered I couldn't do everything that I wanted, so I searched around a bunch for a way to put TWRP on it (never had it on this phone before) and of course no good way. I tried flashing it, and I got the fun certificate verify error trying to get into recovery. I could still boot normally at this point. I should have stopped.
Anyhow, I found a post about flashing the 12b aboot and that would let me throw TWRP on there w/o downgrading and losing all of my data. So, I tried it. Needless to say, this did not work. Now, I cannot do anything really.
If I try to boot normally, I see the certificate verify error with the initial LG splash, then screen goes blank. One red LED and then persistent blue LED until I pull the battery.
If I try to boot into download mode, I get the same thing (except the download mode symbol - which stays until I release volume button) and then screen blanks, LEDS, etc.
Sounds like from doing some looking that I'm basically up a creek w/o a paddle. I can maybe try to get into qualcomm mode (but I haven't found out how to do this), and try to follow these: http://forum.xda-developers.com/lg-g3/general/fix-unbrick-lg-g3-stuck-qualcomm-hs-usb-t2933853.
At this point, I'm thinking that's my only option. Does anyone have another idea, or at least advise on how to get my phone to recognize as 'Qualcomm HS-USB QDLoader 9008 mode'
Thanks for your help...

Thanks @jac10000, I appreciate your help! Unfortunately, that set of instructions didn't work for me. I get an error that says ''Model information check failed' when i try the security error section. I think it could be that my phone won't even show as an LG device. The best I can do is QDLOADER (and even that with special drivers, it plugged in as QSUSB_BULK), even though I had proper LG drivers installed (from previously using ADB...that's how I borked it originally). Do you know of any other things I can try? I've done many at this point and am starting to feel hopeless. Thank you again for trying to help me!

You need a different set of drivers I think. I had a big problem with the qhusb_bulk mode but after installing the drivers I linked on my post in this thread it read as Qualcomm 9008: http://forum.xda-developers.com/showthread.php?t=3072091.
Try it out and report back to us. You should be able to then run the boarddiag tool as per the instructions on the attached pictures of the op in this thread: http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091.
Follow all the instructions very carefully and you should be able to bring it out of a bricked state!!!

I was able to get it into Qualcomm 9008 state, so that's a positive. I tried some similar, but I guess slightly different instructions using board diag and wound up with 'Failed loading flash programmer' errors. I'll try these other directions tonight. maybe if they're more specific I'll have more luck.
thanks again!

I have somehow apparently screwed myself over worse. Before about half the time my computer was recognizing my phone when i plugged it in, and with the drivers, as the qualcomm 9008. But now, I can't even get that! I plug it in in download mode, or normal, or not on at all and the computer doesn't recognize it. I've tried uninstalling the drivers, reinstalling them, rebooting, not rebooting. I opened it up to try and short the test pin, as the instructions stated, but there was a metal covering over the qualcomm chip which I couldn't remove. I am starting to think I'm screwed. I have seen lots of people having success with d550 and d551, etc, but I'm worried the verizon model is different.
thanks again for helping me. If you have any other ideas, I'll try pretty much anything at this point!

I had my VS985 hard bricked when I used "DD" command to mess around to try to put TWRP on it. I tried every possible method out there and I found that they don't work on VS985. KDZ and TOT flash all failed, no ADB. I tried it for 2 weeks and I gave up and sent the phone back to LG for warranty service. Guess what? Even LG couldn't fix it. They had to replace the motherboard! I would advise you the same path. Since your phone is so screwed, LG probably won't be able to tell what you did to it. Just play dumb and say one day you wake up to a dead phone. It worked for me.
By the way, who told you to put a KK aboot to a L rom? That seems to be a sure way to hard brick your phone. OTA does not work with a modified phone (no root, no TWRP). When you get your phone back from LG, TOT it to 10b, Stomp root it, and install TWRP manager to install TWRP. Then you can find the Jasmine flashable zip to upgrade to L. Avoid all OTA stuff.

oh wow, huh. Was your bricked in the same way as mine, showing the 'secure booting error' when you try to start it up in any mode? That super good to know. I may just try. thanks for the advice!
Yeah, I will definitely follow your advice and do that, if I ever get it back! I followed a thread I found, but was clearly making a huge mistake. If only I knew that then!

When booting up, my phone did not show the LG and Verizon start up screen. Even the LED wouldn't light up. It vibrated once, so you know it was powered on. The screen was completely dark. When connecting to computer, the normal LGE device showed in Device manager and I could change the COM port to 41 for TOT flash. However, the flash would fail just like yours. The phone model, IMEI were all blank. KDZ errored out too. KDZ is more forgiving in mismatched phone model, and if even it fails, then you probably cannot save it.

Interesting. I appreciate the advice. I'll probably give it a try, since I seem to be out of other options, but I suspect the secure booting error will be a give away that i did something to violate my warranty.

LG G3 dead. Black screen. No booting. Help????

Hi,
I tried to install a custom rom on my LG G3 d858hk model. I was in twrp recovery and trying to install rom. Suddenly the phone got stuck. I waited for some time and then pulled the battery out and reinserted it. But still no light etc. Even nothing happens when I plug in charger. Looks like its completely dead. Any body any idea, how can i recover it from the black screen.
Regards,
Khurram.

Do you have a warranty for you phone ? do you tried to download mode, fastboot mode and not working? In case the phone is completely dead, I can suggest you the option boarddiag (open phone) and jtag.

Yes I have a warranty. But I had installed a custom ROM (cloudy g3), so I guess that violates mine. The phone is dead, and shows up in device manager as LGE AndroidNet USB Serial Port. Don't even know why its showing up like that
Okay, am i'm searching for any available software fix that's gonna work for me at least before I resort to opening up the phone
Let me shed some light on what caused my phone to go dark, to save someone else from repeating the same mistake... I was trying to upgrade twrp from version 2.8 to 3.0. I thought using autorec would help me achieve that. But once it had finished, I attempted to boot to recovery and since then my phone has gone completely dark
OK, you could try to carry the cellphone to LG support and you can tell that after an upgrade, your phone has not returned to turn on. Usually, they change the motherboard. If you want to do it through BoardDiag, here is an explanation:

Thanks for your help. Ive been able to get my phone to 9008 mode. So, am getting the part where I have to use the boarddiag tool, but am abit confused. What should be the value of my target dir, and AP chipset?. For the chipset, i'm thinking I should use the value that's similar to the one at this guide

The first thing you should do is download the .tot file corresponding to your Variant (D855), I think that you can find it here: http://forum.xda-developers.com/lg-g3/help/tot-dll-file-d855-t2859828
Follow this guide to use boarddiag:
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
In the "Image EXTRACTION" sections, in "BIN" must locate the file .tot that you downloaded.
In "DIR" you put the location where will be extracted the content of the .tot file.
Note that "DIR" and "TARGET DIR" should be the same location.

And then, every time I unplug the device and plug it back into the PC, the device ends up being undetected by windows, and I have to redo the shorting procedure again. Is this normal behaviour, or something is wrong??
Also, when I put the battery back, and plug the device, it shows up as LGE androidnet usb

I had be not dealt with edl on LG in a long time been on Samsung for a while that being said i could suggest maybe be uninstall the current 9008 driver and try to find a different source or updated and or try other usb ports. We on s8 have a lot of issues with usb 3.0 ports on pc's

VS986 Hard Bricked

So my VS986 wont boot, light up or anything. No download mode either. Saw a tutorial on a fancy http://www.droidsavvy.com/unbrick-qualcomm-mobiles/ unbrick method however it didnt work. The only thing I can get is in device manager under Ports - Relink HS-USB QDLoader 9008 Com4. Sadly nothing came up under disk drives. I havent been able to really find anything on fixing it from this bad. Most threads fell off around a month ago with no more replies. Any ideas?
You might want to supply a little more info. How did it end up like this? What were you doing when it happened?

Well I was removing xposed so I could try and get Snapchat to work. That didnt go so well. Decided to flash back to factory. I think I may have selected the wrong kdz file using the LG Flash Tool via CSE Flash, but I cant confirm. ANy other info you would like to know? SOrry for lack of info, first time its happened this bad.
I can't remember will flashing the kdz wipe my rooted system img off my internal sd?

I hard bricked my phone while trying to root. Tried various steps but nothing helped.
Finally I did an RMA. Sent to LG. They loaded 13b and sent it back. The whole process took a week. No charge. They even covered shipping both ways.
If nothing works this is an option.
Why would you need to remove xposed to get snapchat to work? I have xposed with 2 snapchat modules downloaded and snapchat works fine.
I'm in a similar situation.I am using the Droidsavvy giude for the qualcom tool QFIL. I have gotten my phone to get the "Qualcomm HS-USB QDLoader 9008” MODE.
I need the "Flash.xml file " and the right rom type files to possibly restore my phone. can anyone help?
(nothing else will work I have tried all flash tools and still only the ( 9008 mode will come up)
Such a hard brick *might* happen if you downgrade. Or at least that's what I think happened, because although it's not often, the partition table does get changed every once in a while. And when it does, you can only move forward.

I have lg g4 ls991. mistakenly flashed a lower version firmware thinking it was the latest. the device is now hard bricked. no power, no download mode. luckily, I have extracted the firmware form the phone before bricking. I came across a few post where its possible to fix via sd card direct emmc. You will need to have SystemImage.bin file and win32Disk Image. I need someone to assist me on how to create the SystemImage.bin file. any help will be greatly appreciated!

I didn't had the same issue as you, but had a similiar one (phone didn't get discovered neither by LGUP nor LG Flash Tool). Yesterday I fixed it by following this guide:
http://forum.xda-developers.com/showthread.php?t=2785089
In particular the part where you change your device to COM41 in the device manager.
After you get it discovered by LG Flash Tool flash an official KDZ.
Reboot the phone and connect it to your Windows, allow the connection from the phone screen.
It should promt you to install drivers on the computer, do that (they are different from LG Drivers you download from the web mind you)
Now you can change your COM port back to 3 and everything should be fully discoverable by both LGUP and LG Flash Tool.
I think I replied to you on reddit (same photo) Have you tried plugging the phone in while in download mode ? Did you try installing drivers from the internet ? Coz thats how I fixed the same problem you have.

Exactly, here I am running around in circles over this BOOST Stylo 2, just got it with MM 6.0.1 out of the box 2 days ago. I caught the 454.4mb update it has been trying to do! Got that baby downloaded! 1.02gb unzipped and renamed to kdz. Got a script for Terminal that will replace Kingroot's temp root with SuperSU but I am not going to attempt any further until I know LGUP will recognize and flash my .zip the bas****s deem not worth enough to put up for download on LG's site!
I got LGUP to recognize it in download mode, reads out LGLS775 but still says it cannot open it...............
His info on how he got it to work would prolly have solved this dillema..............
oh well

ok had a LG G3 that's done this- as long as you can get download mode it should recover, YOU need to use the LG mobile support tool from LG website ( LG UP sees phone as unknown model ) run LG mobile Support tool and in option choose UPGRADE RECOVERY . follow instructions and allow to start process, it took 57 minutes to repair my phone - it will seem frozen anywhere from 0% to about 22% JUST WAIT IT OUT!! lg up / twrp flashes in 5 to 10 mins -- the LG m.s.t writes block by block and takes 1 hour +
so hints and info took 3 goes to find and start upgrade recovery - error on a couple of attempts. phone seems frozen around 10% and 15% of firmware upload -- go make a coffee drink it, go pee then come back and worry! A watched pot never boils!....

It didn't. It's EVEN MORE broken :'(
I figured out how to get my PC to recognize my D851. Apparently all the LG software didn't like how many COM ports I have. As soon as I unplugged everything else from my PC, the software worked. In this case, it was LG Flash Tool 2014, but I couldn't get any of them to work before.
Try running LGUP as Admin!!! For me it worked!

Hope someone can help me. I flashed a rom for a d855, d855g30 I think, and although I can access download mode all aps for flashing fail saying it's the wrong model number. Even the generic DLL file cant trick it. It still starts booting the rom but boot loops before entering. I no longer have twrp and when I try to do safe mode or factory reset I get a boot validation error or something similar. Just seem to be stuck. Im using a VS985.
One cause of LGUP "UNKNOWN"
While an old thread, it'll be found in searches. For anybody who gets "UNKNOWN" device with LGUP for the LG G3, I found that LGUP for the G3 is often distributed with the wrong DLL file. See the details here, post #11. After installing LGUP, make sure that the "model" subdirectory in the LGUP program directory is the same number as the processor in your phone, in my case c:\Program Files (x86)\LG Electronics\LGUP\model\8974 (was 8994 with the "LGUP for G3" I downloaded).

It's probably not lost, but you'll need to get to work & it is a mild pain in the a** to do so...

Dont mind the sprint variant, just use the proper files for your phone this time around
I brought a phone up last week via this method. The hardest part is getting the phone to show up as qualcomm 9008 & to communicate with it(need the proper drivers and need a good cable). It can be a little tricky, but once you figure that part out the flashing part is easy.
*The method I linked above should be considered a last resort.*
But I thought you posted you can get into download mode earlier, so make sure your computer isn't the issue. Uninstall all lg drivers & reinstall them. If you have download mode/firmware update displayed on your phone screen and it shows up as lge serial port(or something like that) in device manager you should just be able to TOT or KDZ your stock firmware. I believe there are instructions for that in the link as well; if not - google is your friend.
Gd luck:good:

[problem] lg g3 d855 unrooting and installing stock ROM from Fulmics 6.9

So I got my lg G3 a while back, and until a couple of weeks ago it worked perfectly fine, rooted, custom recovery and custom ROM's(currently running Fulmics 6.9 on it).
Then, I noticed it started to fade to black(a well known problem, not the subject of this thread), and I want to send it to a care taker, since technically the time period of warranty isn't over.
So, I began to try and unroot it according to multiple internet guides, failing time after time. then, I noticed I don't have download mode, and it goes into safe boot mode instead. On top of that, I can't access my bootloader. I tried several methods, some including LGFlashTool and LGMobile support tool but with no success. So, considering I'm not exactly an expert in this matter(I'm clueless about what to do) I come here with a request for help. Any help is much appreciated and I'd be happy to provide any extra information if needed. Thanks a lot in advance.

Take a look here, if you haven't seen that thread already. Since you are on MM right now, you need to use LGUP tool. The full instructions are in the Post #3 in the thread; just follow them. Note that you don't need to enter the DL mode - just keep your phone turned on, and plug into your PC. As long as you have proper drivers installed, your device will be recognized when you launch LGUP, and you should be good.
I personally haven't tried this going back to stock from Fulmics, but I did successfully use this method several times when I was playing around and trying to root my phone and install TWRP.

so I tried following the instructions in the thread you provided, but LGup doesn't recognize my phone so i cant enter it.
tried looking for a solution but i cant find anything. I'd appreciate it if you could help me.
Thanks.
EDIT: I've figured out the identification problem but lgup does require Download mode, it just enters it by itself.
this brings me to the original problem-I don't have download mode hence I cannot use lgup.

Hold VOLUME UP while connecting phone to pc and it will enter download mode. Then start LGUp and flash kdz by following instructions

When I try and start download mode it writes fastboot mode and then the screen goes black and the led flashes red and blue. I tried to look for a solution for it but couldn't find anything.

OK, this I don't know how to fix, sorry... I was thinking that you just can't enter the DL mode manually for some reason, so the LGUP tool would do it for you. But from what you are saying, it appears that your phone can't enter the DL mode, period. That's really weird, and I have no idea what can be done in this case...
