LGE AndroidNet USB Modem not recognized, and hard-brick - G2 Q&A, Help & Troubleshooting

Good morning everyone!
Yesterday I flashed into my LG G2 D802 the CloudyG2 3.1 over the last Lollipop firmware. I didn't like it too much, so why not returning to the stock?! I wiped everything with the recovery and I put my phone in download mode, how I did a lot a lot of times (not a newbie in modding). But this time is different. When I plugged my phone on my computer, it didn't recognize it.

I've tried with all possible ways. I have naturally LG drivers on my computer, last version, but the situation doesn't change. I tried many times to uninstall and reinstall drivers but this is not the problem. I also tried to switch computer, reinstalling there drivers, but always the same! I really don't know what to do. It's bricked so I can't do anything with the phone turned on, I've only access to download mode and to TeamWin recovery (I tried a lot of times to rewipe everything again, nothing).
Please please help me!

Device no found after 4.4

Hey,
I'm using 4.4 and I want to put 4.4.2. Problem is that I'm rooted and bootloader unlocked. So I need to put a new bootloader in other to get the OTA update but I can't because no matter what I do, I get Error: device not found.
All drivers installed and reinstalled many many times.
Have you tried going into developer options and selecting "revoke USB debugging authorization"? Then plug your device back into the PC ....

Hey,
I don't think that is the case since I have a brand new Win7. The phone was never connected to it. Anyway I tried of course and it didn't work.
I plug it on the PC and it asked for authorization and I give it. Then I disconnected, turned it off and went to fastboot mode. Re-pluged and no detection.
RSD Lite detects but adb no.
Have you tried PTP (camera) mode?
Or this

LG L5-II doesn't boot up, only goes to download mode

Hi,
I have an lg e460 (L5-II); when i boot up it's stuck on the icon of android update

.
It doesn't move on; the only thing that i can do is go to download mode: i've tried many things, installing software with lg mobile support tool and with kdz software but without results.
It looks like the phone is recognized by the computer and also by the software (i've already installed all the drivers, tried to disable the lg modem in device settings in windows); while installing the firmware on the phone there is just the write "download mode" without the % of progress, and after the it finish at about 94% the phone reboot and all it does is again being stuck on the icon of android update.
It doesn't go in recovery or in emergency mode.
I don't know what to do anymore.
Is there anyone that can give me some advice?
Thanks in advance.

USB device not recognised - toolkit, reinstall drivers, nothing works!

Normally whenever I connect the phone to my PC (Windows 10), the normal USB options screen would pop up on the phone, giving me a choice between charging/file transfer etc...
a few weeks ago it stopped doing this, and the same result on my other pc's.
maybe its to do with the big windows 10 update that was rolled out, I don't know.
but anyway - I simply cannot get windows to recognise my phone at all, it just says

I have tried reinstalling windows drivers, tried the toolkit to install the drivers, restarted phone etc, nothing seems to be working.
I don't know what else to do, please can anyone help?

This is what the device is recognised as even after installing many different qualcomm drivers; I have the correct Msm download tool on my pc too(Phone not detected); im relatively new to this whole process but my understanding of computers is intermediate to say the least, Device with touch installed worked perfectly; shut it down to charge one evening; woke up to it not powering on with the power button but I managed to put the device in EDL mode. I'm not sure what else you guys might wanna know but for sure ask any questions you may need to help me in my recovery; i'm hoping to flash the phone back to stock and already have my desired image installed. TLDR; the poor guy aint being detected and I don't know why because im a noob
Tried multiple USB cables, PC doesn't have a USB 2.0 Port, installed oneplus usb drivers,
