LG G3 is bricked, unable to turn on, and Code Error 43. NEED HELP ASAP!

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 found the problem. After doing some research, my phone is being half brick and I'm on Qualcomm HS-USB QDLoader 9008(COM3) port 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

I had the same problem .. I tried to update my phone with ota and the same happend to my phone .. I downloaded the latset stock software it was .kdz and i used lg tool and from control panel i changed the port to 41 and it did work

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.

nothing just black screen no led either but the computer recognizes the phone on devices settings it shows LGE androidnet usb serial port.
i tried every guide here on xda to unbrick and a few on other sites and noghting

the only thing i did not try yet is a tool called lg smart boot diagnosis tool that theres nowhere to download only an xda member seems to have this tool but im waiting to see if he can share the tool or no

I dont have much experience with lg yet but if there is a flashing tool for it since u can still get the computer to read you just the tool and stock rom reflash and startover

i tried that already the problem i got now is the phone cannot get to be on download mode lg flash tool gets me an error that can't change to dlmode. it seems im running out of options maybe i should send my phone to lg for repair but i rather not i would like to try a little more before doing that

To put it simply if you cannot get to download mode, at this time you are sol. Maybe in the future if we get the qualcomm files you could fix it if your pc recognizes in one way or another it is connected under ports. But right now as we stand we do not have the files to recover from your type of brick.

thanks for you reply it seems that im gonna have to send it to lg for repair i bought it second hand so t-mobile will not help me with this.

Can you get adb to recognize it? You might be able to extract the laf.img and use adb to flash it back to your phone. Then you'll have download mode back.

no adb either i tried that. i try all kdz methods,flash tool with tot file and modded dll it gets stuck on can"t change to download mode. thanks for asking

the only method i did no try yet is the lg smart boot diagnosis tool that a xda member has but dont wants to share the tool

no nothing happens just a black screen

Black screen might not mean its not doing anything

This is true but two problems exist:
1) Correct me if this is wrong, if you brick your phone and don't automatically boot into fastboot mode there is no way to do it. You need to flash the full fledged laf.img so it is booted when you do the vol + plug in instead of booting to lg boot loader.
2) Even if his computer can recognize the phone what he has done probably makes it boot into QHSUSB mode and at this time we have no solution to fix it.
I have read somewhere on the g2 forum of fixing one of the types of QHSUSB bricks (they come in a couple of flavors) but I can't remember which one. I do remember he needed to flash the full fledged fastboot laf somehow then flash the aboot partition via fastboot. So if I was you I would do some digging in the g2 forums.

thanks everyone for trying to help.well i just send my phone back to lg for repair i will inform everyoneif lg repair my g3 or not thanks again

LG G3 D855: Bricked After OTA Update

Please help with my bricked G3 (D855)
Hello!
i would like to ask you, that can you maybe help me with my LG G3 (D855). I live in Europa, Hungary
I bought the device as used, and i would have liked to download the latest software via wifi, then on the phone restarted, and was only the TWRP on the phone, i restarted the device again, but i could entry only in the TWRP. I downloaded a ROM from the XDA (G3 Cloudy), and i made a mistake, i installed the D851 software. The phone is bricked, no download mode. I tryed to unbrick, but every method need the download mode. If i put the device on the PC, the PC see only as modem. LGE AnroidNet USB modem, and the the port name LGE AnroidNet USB Serial Port Com4. If the battery is low, i see on the display, that show that need to charge, but nothing more life signal. If you can help me with some information or via teamviewer, i will very glad for you, and naturally also donate. As i wrote the PC sees my phone only as modem, and LGE AnroidNet USB Serial Port Com4. I downloaded the QDLoader HS-USB Driver_64bit for my PC, but i dont see Qualcomm HS-USB QDLoader 9008 between the ports.
I hope that someone can help me. Sorry for the bad english.
Have a nice day!

May be a dumb question since u don't have download mode, but can you enter recovery? If not you may be hard bricked as recovery and download are your only options and if neither work....

no, i dont have recovery mode

No download and no recovery mode, seems ur hard bricked. Sorry to say, I May be wrong but I'm pretty sure. Flashing different models is detrimental.

Even though you installed the D851 version of Cloudy, you should still be able to enter TWRP. After a battery pull, you're holding down the power+volume down buttons until the LG logo appears, then releasing both and again pressing them until the Hard Reset menu displays? In the future, never take an OTA update if you have a third party recovery like TWRP or CWM installed.

I cant entry in the TWRP, no download mode, no recovery mode, nothing
can someone help me?

Give a read through this thread...

so does anything show up when you turn it on? how far does it get in booting? it goes to DL mode everytime? and that's what is in device manager in DL mode?

it boots into dl mode but i cant flash firmware yesterday i recorded it. it boots to lg logo and after 29 seconds it boot to the android guy i did find something in yellow text but it flickers and that says. in short
E: failed to mount /cache (no such file or directory) then can't mount /cache/recovery/log
can't open /cache/recovery/log
and it repeats that text 3 times from what i saw

did you install twrp? i would check your drivers or the cable for the communication failure in dl mode

My goal is to try and install TWRP my phone fully stock I checked everything even my charging port. I'm using the lg cable... My main goals are to get this fixed before March 3 and all I need is an alternative. Get TWRP or return back to stock

at least give me a script to boot to stock android recovery without adb. cause obviously i cant use adb and i hope anybody reading this can remember that with lg flash tool 2014 kdz method it goes to 4 and stops unless you guys find fix to that. all i need is to get this thing fixed before march 3rd. so if you guys help me find any kind of fix this is all i need
here is info but my phone
model: lg-d852 (don't really need it though)
status: stock unrooted device and has never booted into the system
android version: 4.4.2 kitkat
main problem that needs to be fixed: it cant mount cache cause apparently there is no file or directory according to my phone
that's it. if you guys need anymore info about my phone let me know (except imei or serial number cause that's all private stuff) thanks

I used every method

then you must force it into the 9008 mode using the following guide. I would check the dll you are using, drivers, or cable first through. I would be EXTREMELY SUPRISED of a g3 in DL mode that is non-responsive.

i'm surprised that my lg g3 in download mode with the correct dll, tot, kdz. every single program with a fully working charging port and an lg cable is that unresponsive. although at one point the arrows in download mode started spinning an then it stopped and on the monitor it said on lg flash tool (tot method). CAUTION: Primary gpt has invalid value there must be something blocking the connection
oh and my phone is still getting fixed soooooooooo no updates just yet. but like i said if there are no results i'll update you
