[Q] PLEASE HELP! T-Mobile LG G3 Hard Bricked!

So today I tried flashing android 5.0 on my T-mobile LG G3 D851. I put it into download mode, started the flash and waited. My LG flash tool then crashed and closed. My phone was %6 through the installation however and was just left frozen after it crashed. I tried every way possible to restart it and get out of the screen while keeping it plugged in, but I couldn't...so I took out the battery and put it back in. Now nothing is turning on, I can't put it in download mode and the charging LED doesn't light up, etc. It's completely bricked....what do I do? I've already tried taking out the battery and waiting and plugging in the cord and then battery. Please help! I can't afford the insurance or another phone...
EDIT: Also the battery does have charge...although I don't know how long it will last.
EDIT 2: I just realized this flash was for the 855 variant..not 851. Does this mean that I am just screwed?

It means that you got expensive brick.
You cant enter into download mode or recovery?
Probably only help is jtag. Find someone who can do that.

Sounds like someone has learned a very expensive lesson! Have you tried to factory reset it?

Yeah JTAG is all you got if no download mode

The linked solution works only if the device shows some signs of life - atleast a boot logo.
i have a D851 that a friend bricked. She tried upgrading to Lollipop and flashed the AT&T baseband on this TMobile version. The result is a hard bricked device which does not even seem to power on. Shows no signs of life, except when connected to a windows pc. It shows up as 'LG Androidnet USB modem' in the device manager. No boot logo, recovery, or download mode. Fortunately she has IMEI and twrp backups for this phone (boot, efs1, efs2, radio, rpm, tz). I did some research on JTag solutions. Unfortunately, none of the boxes support the D851, yet.
Any ideas on how to recover this device would be greatly appreciated.

[Q] Help to unbrick my LG G3

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.

Help please. Lg g3 Might be bricked.

I switched the phone screen due to a damage thingy I had the nightly version of the Cyanogen 12. latest version and did alot of problem with my device overheating issues and alot of stuff i did the purple drake rooting guide. so at the end i ended up deleting all the data in the sd cards and i cant enter recovery mode. my computer cant detect the device as well only lg logo comes up and the phones seems dead. what can i do to solve this ? :/ I feel hopeless

[lg g3][hardbricked][emmc fail]

So last night my phone just died.
Nothing is working i can't turn it.
I tried everything on xda and nothing helped.
I was running fulmics rom.
I tried using BoardDiag and it failes during emmc tests. It says boot partition write FAIL.. sector 0x30000
I tried erase on emmc and it passed but it wont write anything on it.
So I don't know if my phone is completly dead or i can save it.

Bro. I had that issue too with lg g3 sprint. Tried board diag. And nothing works. Mine was showing qualcomm 9008 on windows device manager. You might need to j.tag it to see if it will be able to boot to download mode. Mine i had to swap board with lg g3 verizon from someone with a broken screen. That's how i got it back.

(i installed slb1 without battery and then unpluged phone, put battery, hold volume up, putted usb back into phone and tried to put phone into download mode. IT WORKED!! )
And Thanks for replay

I was in the middle of unbrick my g3 from hard brick to soft brick. I flash firmware using lg up at 99% then the phone died as it tried to reboot. It won't boot at all. As you said when remove the battery and connect charger, i can see my motherboard working with exclamation mark. As soon as i put the battery, motherboard out and no sign of life. Is this sign of bad battery or what. I don't have spared battery

I recommend first, to users with similar problems, to try first my guide in following link and after the pins in motherboard-tot files

I have D858HK hard bricked for 2 month and i use v10d to flash every partition. Then it won't boot into recovery. When i use v985 .tot, it successfully boot into recovery. Also on LG Smart Board diagnostic, my model not detected. Even if i manually select, nothing happen when it reboot. Right now, i have no idea whats wrong as i spent countless of hour on google and XDA.

I can't even enter download mode. I use win 10 64bit with all driver installed and disable integrity checks and everything
