So....... my LG G3 had a new OTA update for T-Mobile and I was an idiot to download and install the Update(YES I WAS REALLY DUMB TO DO THAT). So when my phone restarted, it automatically went to TWRP and I couldn't boot to system. I tried everything from hard reset to fiddling with the settings. When I attempted to turn on my phone, it wouldn't turn on even with charging the phone, using the buttons, and especially when I plug my phone into my computer. It gives me Code Error 43( Unrecognized USB Device) and now I'm in a hellhole attempting to fix this device by tomorrow. I need help ASAP before I lose my mind
P.S I'm rooted with Purple Drake and using ZoneROM
Can you boot into Download mode ? (Device turned down hold Vol Up then plug in to pc)
Nope. Can't even turn on the device and keeps on saying error 43. PLEASE SOMEONE HELP ME OUT OF THIS NIGHTMARE

Try to plug it on another usb port. And when you try to boot into download mode nothing happens ?
Yep! For two hours straight and I have all the drivers downloaded. Drivers worked perfectly until it turned off.......
I hope it turns on before tomorrow. Keeping my head up until it is fixed
http://answers.microsoft.com/en-us/...cognised/6a2a5531-8b80-4798-9aa6-ee2dcb705c7f
and if that doesn't help try to uninstall that Unknown Device from your device tree in Device Manager and install the drivers again.
That didn't work either. I believe its my LG G3 because I was fiddling with the "SD Card Partition" and it had an System Fat32 error and it shut my phone off completely and now it won't turn on after that. Is there a way to reset or reverse my Partition settings?
Update: The phone is charging on my portable charger but won't turn on nor connecting via Windows 8.1
I found the problem. After doing some research, my phone is being half brick and im using Qualcomm HS-USB QDLoader 9008(COM3) but I don't know how to push files or how to use qhsusb_dload on the LG G3. PLEASE HELP ME

I've never seen a device that doesn't boot into Download Mode.
So you're doing everything exactly like this man does and on 0:25 you can't see that Download Mode icon ?
Nope not working at all, either its trolling me or its officially dead. It just says im still ported into Qualcomm on my screen instead of download mode
Please help guys, I really need help before tomorrow. No boot, no screen,no download mode, no usb connected except for qualcomm hs-usb qdloader 9008 (com3) and can not use lgflashtool. Does this means its a hardbrick and I can't do anything to unbrick this device and I need to call T-Mobile for another phone or can the dev gods help me fix this phone problems soon. Please answer asap
U said, u fiddle with the sd card partition which I think shouldn't do... Best option is to take back for a replacement or repair my friend...
Thats the only option? I heard there is another way to reset it

Put the phone into download mode, go into device manager, ports(COM), you should see LGE then right click on properties, Port settings, advanced, then change COM port 41.then click ok and you should be fine.

It has to be similar to this but I dont think the LG G2 variant would work on this and forgot to mention the usb is called qhsusb_bulk
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.

its bricked. but why how,? but well. i think you must send it back for repair. i think i have hears people telling LG that while you were upgrading using LG bridge it didnt finished and i guess they should fix it. or unless you use service like JTAG but its called diferent i think.

Hi everyone
I having this problem with my lg g3 d855 ... My phone was at 5% then i wanted to remove kingroot because i wanted to flash super su. After uninstalling kingroot (in the app) the app crashed ant after few seconds my phone turned off... i was thinking my phones battery just died, but i was wrong. My phone wont turn on now :/... Only response i get from it then i plug it in the charger without battery (it show no battery error)... then i put battery in, screen goes blank.
And also i installed twrp using app from store (Forgot the name, but for d855 model)
*LG G3 D855 Android 6.0 official* (if needed.)
i tried:
holding power button for 15sec without battery and then charging it... Didn't work :/.
Putting another battery (Galaxy s3... Charged to 30% at least. I don't have another lg battery ), same result.
New battery also doesn't do anything...
EDIT:
i tried method in http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359 but i can't find nor make .tot file :/ anyone can link mby?

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.

Hello there pals, I have a problem, I have an Lg H815P (Mexico Version), and i was using it normally for about 15 days, then suddenly the home screen freezed, and then the phone restarted, i thougt it was just a lagging issue, but then, when the phone booted up again, after like 5 secs it freezed up again and restart, a infinte loop, then i said, this Rom must be corrupted (Stock TELCEL Rom v20b Android MM), and decided to do a hardware keys factory reset, then the phone restarted but when it was android upgrading apps, it kept restarting, at last it booted up but the problem persist. So im kinda worried, how a problem cant be fixed at a full hard reset? When im trying to flash a KDZ file From lg flash tool, the program fails because cant find phone, a kinda weird thing because the adb detects it sometimes, others not, i booted the phone in safe mode and the problem persist anyway, what can I do? I already have the drivers, the lg up, and the lg bridge apps, they all said that im running the last software for my mobile device, i´ve tried another battery as well, so im kinda lost, another thing, after the hard reset, the phone was able to stay on like 15 mins, sometimes 5, sometimes just secs, dunno what is happening but i really need some ideas, can you help me to work this out?
Greetings pals!

I have had this problem occur because of the launcher. Try cleaning the cache and data and see whether an updated version is available. You could also try a 3rd party one and see if that helps or simply re-install the LG launcher.
If no luck, you could try flashing another kdz with LGUP-NEW: https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
There are a couple of TCL kdz's listed on this site: https://lg-firmwares.com/lg-h815p-firmwares/
Scroll sown to LG H815P Firmware List.
Back up everything first.

Make sure you are using the correct LG Mobile Driver on your PC: LGMobileDriver_WHQL_Ver_4.2.0
If you are using the drivers your PC installs, you will have issues. Check in Device Manager on your PC.
Use LGUP-NEW to install a kdz.

If the phone is still recognized on your PC, see if you can get into download mode. If you can, try re-installing the KDZ from there. Make double sure it is the same kdz that was installed on your phone when it worked.
The other option is to see if you can get into recovery mode and try a factory reset.
It is possible that the freezing you were experiencing before when it booted up was, as raptordd suggested above in post #4, an early sign of the hardware bootloop issue that has now manifested fully. The only real option then is to send it in to LG for repair and tell them your phone, you believe, has developed the hardware bootloop issue. Even if out of official warranty, they should replace the motherboard in that case, at no cost to you.

Now that u mention that, the phone was recognized by pc, but i installed a lot of kdzs, and none of them made the phone boot, every one of them were for h815p v20a, the one that was installed, but now i connect it to pc and then says download mode but doesnt enter and then the lg logo appears again, even the charge is meesed up now, i think i screwed the download mode and the charge mode, is that possible? but i tried the factory reset when i had the working firmware but the problem persists. Now im thinkin my only option is to use a octoplus box to revive it, but dunno if that will fix the restart problem, about that warranty stuff, i can send it to lg mexico and they should change my motherboard for free? That sound too good to be true.

See if you can enter recovery using the hardware buttons and try executing it again.
LG has been replacing motherboards in a lot of cases where the issue is attributable to their own hardware issue (ILAPO). You don't really want to discuss the things you have done to get it working again with them ... if you get my drift, i.e., play dumb ...

Ok if none of the baove works, ill do that, but no, it has no recovery neither, not even stock, i read about a bootloader way to fix the download mode, im gonna try that but i doubt i can cuz bootloader is factory locked cuz is latin version.
No luck at all, phone is still bricked, is there any way to flash stuff via bootloader or abd without bootloader unlocked or root?
