LG G2 Hard Bricked? - G2 Q&A, Help & Troubleshooting

Hello friends.
Just today I tried to flash CM13 on my D802. I did. After that, I pressed reboot system as usual.
This is the weird thing: after pressing that, the phone showed the LG logo for a second then the screen went full black.
Now I can't boot the device. I have download mode available... No download mode though.
When I plug the device to my PC I get a ton of Windows Explorer prompts saying "You need to format the »something« in orded to use it". Like 10 of these.
Please help? I still have download mode available to me.
I already tried LG Flash Tools to return to stock but when it gets stuck on 60%. Then i get the message "the phone is disconnected from PC or USB". When I try the R&D Test Tool i get the message "Port or Serial not found"... Please help...

D802T won't boot past the LG Logo

Here's the story in brief:
I connected the phone to LG PC Suite, it offered an upgrade to D80220C. I started the update, and left the phone connected to PC Suite over night to allow PC Suite to download the file.
I wake up in the morning to find the phone stuck on the LG Logo with the LED blinking like it does on start up.
Since then, the phone will not boot past that logo.
I tried the few guides for Stock ROM Flashing, but LG Flash Tool always says the phone isn't connected while in download mode.
Can anybody recommend a way to make the phone work again anyhow?

I cannot Factory Reset the phone, it gets stuck on the LG Logo itself. And I am unable to use the Flash Tool as well in Download Mode as Windows Keeps saying phone is not connected.

[Q] Phone bricked, no download mode. Please help.

Hello,
I've looked for solutions everywhere and have spent the last days trying to fix my phone but i can't find a solution. Here is my problem:
I bought a second hand phone, it was working fine however it had been rooted and was running on Cyanogen.
I therefore tried to revert this to a stock EU ROM I downloaded. I was able to do this through the LGMobile Support Tool.
However when the process completed, my phone was stuck in a reboot loop on the LG logo. So I went back to the LGMobile Support Tool and selected 'Upgrade Recovery'.
After completing this, my phone was still stuck on the loop, but now I'm unable to access download mode, or recovery mode.
My phone is detected in device manager as LGE AndroidNet USB Serial Port (COM4) and LGE AndroidNet USB Modem when plugged in.
I don't know what to do? Please help.
This is now resolved thanks to bender_007

Try wiping through stock recovery mode (hold volume down and power, wait for lg logo then hold volume up and volume down-without power button)

Mode download doesn't work

Hello,
I want upgrade my LG G2 with a new rom 5.xX
This phone have only the operator update. No custom, no trwp, nothing...
I installed drivers and when i want access to download mode. I can't. I use the good proccess with vol up then plug usb cable always with vol up presses.
follow this procces after a little moment my phone show me battery logo charging.
So i can't access to download mode.
I would use this process
t was NOT bricked. I finally tried playing around with the LG Mobile Support Tool (B2CAppSetup.exe). Of course it detected that my phone already had the latest firmware from T-Mobile, but then I clicked Options>Upgrade Recovery.
It downloaded for a while then I noticed it had put my phone into download mode (it said "Rooted" in red letters at the bottom). Then it flashed the same firmware over and I immediately tested, it entered download mode right away. But I didn't end up needing that as Stumproot was able to brute force it now after the recovery flash.
Anyway, I couldn't find an answer anywhere else. Most results also have a bricked phone, but that wasn't my issue. This solved my problem and maybe it could work for others.
but it's impossible for me to install B2appsetup on my pc the installation begin then stop after 5s then nothing.
I have Win 10.
Do you have a solution for me , please??

Were you using a custom recovery? (i.e. TWRP)? If so, are you able to boot into recovery? It was a few years ago but whenever that happened to me I would have to use the hard reset option. If I remember correctly, on my LGG2, I would hold down the power button and the volume down button at the same time until the LG logo appears, then right when it appears, release and re-press both buttons again holding them down again until the hard reset option showed. Then when it asked me if I was sure I wanted to reset my phone, select yes (it made nervous the first ten times or so). Eventually I began to trust it would, in fact, do what I was informed it would do which was boot into TWRP without actually resetting anything. From there I was always able to flash a new ROM etc. Anyway, if you knew all that sorry, just trying to help. If not, please get second opinions since I will not be held responsible for your device and since it's been years since I tinkered with mine. Having a Samsung now, I don't mess with it cause rooting a Samsung Note trips Knox and then Samsung Pay is disabled.
Anyway, happy flashing and best of luck to you. It was an awesome hobby while I was involved with it.
Cheers!

First of all power of your phone by long pressing power button until screen light goes off completely
Then keep pressing volume + button and connect it to PC via USB cable. [DOWNLOAD MODE]
Now you must be in download mode, simply flash stock firmware.
If you can't enter download mode then you might be in fastboot mode.
here are some threads..find out which one is related to your problem follow instructions carefully.

Thank you my friend for all your answers. In substance;
I can't open my phone. (Staying at LG logo screen.)
I can't do "Hard Reset" with phone buttons. (Because of "boot certification error" screen.)
I can enter "Download Mode" but I can't loading any .KDZ file with Flash Tool. (Stuck at %2)
My computer can't see my phone when I plug that.
Very hard situation. :crying:

Reinstall LG drivers and PDA
then connect phone with PC in download mode.
open device manager and search for 'COM ports' list if you see your device there then you are ready to go.
If your device is not there then search under 'Other devices' and manually install drivers.
If you can boot into download mode and still you can't see your device in your PC then it's not problem with your G2. It's your PC which is causing it all.
Try another PC.
