[Q] VS980 driver help

hello xda, i have a vzw vs980, that is rooted using towelroot, and has twrp achieved through autorec. I am currently on stock 24a 4.4.2 kitkat, but want to flash back to bone stock. i have all the files i need. I have installed the vzw g2 drivers 2.11.1, but when i put it in download mode and connect it to my computer it begins to install on my pc like it should. on my phone i see the download mode screen with the word "rooted" in red in the lower box. i also see B57 in grey. my status bar on my pc just randomly dissapears, and my phone stays at 0% the whole time. i was able to boot back up into my phone, and all is well. i went to lg support, and saw that there was new drivers for my phone, 2.16.1. i havent tried again with these, but my question was that if you knew what my problem was, or if the outdated drivers were the problem.

[Q] Stuck at security error

Hi everybody!
I have Lg g2 D802 Baltics. Yesterday I tried to return to Stock KitKat via Lg mobile support tool and Flashtool, both of them didn't work, they just didn't find my phone in download mode. Then I decided to reroot and reinstall TWRP. The first was done and the second too, but unfortunately my phone restarted and got a Security error and LG logo and can't boot, just permanently restarts. I've already read a hundreds of articles like http://forum.xda-developers.com/showthread.php?t=2432476 . The method written here isn't working for me because the Flashtool just can't find my phone when trying to install a firmware. So, any program like Lg support tool and Flashtool don't find my phone, so I can't do anything with my phone to get it to work. I'm facing i real problem for me and i'm quite shocked. So, please, tell me what to do, how to fix my phone. I tried a lot of thins, nothing helped. What to do?

Problem Going back to stock !

HI There ! I own a LG F320L for sometime now. It came with Kitkat 4.4.2 installed and then i flashed it with CloudyG2 rom and have been using it ever since. For the past 1 month I have this strange touch screen issue with erratic behaviour and phantom touches. It has been addressed as software related issue and going back to stock has fixed some of the users problem.
Now to the main issue, I followed the tutorial of LG FLASH TOOL Method upto the point. Installed drivers and have downloaded the KDZ for stock kitkat but when I enter the download mode and LG flash tool begins to start it doesnt even verify my phone. It keeps stopping at 2% software extraction (sometimes 4%) and then a dialog appears saying Disconnect phone and remove battery and then again put the battery in and connect your phone and try. I have been trying it for many hours but it doesnt make any difference. I have used unrooter tool to unroot my phone for download mode. I have also tried the TOT method for going back to stock but no success. Whenever I plug in my device it appears in device manager but it is not recognized by FLash tool still. Please help me. I have TWRP 2.8.4.0 Recovery installed.
I am running windows 8.1 X64. The drivers install with no problem.
P.S I have searched all the threads regarding flash tool problems and download mode recognition. I didnt find anything helpful.

Download mode and LG mobile support tool not working

Hello all,
usually i deal with my problems by searching the forum, though this time i am really worried as i cant find anything to my help.
You see something went bad with the screen and because the phone is rooted, i cant get it fixed (it is still in warranty), nor can i use it (the touch sucks).
So i am trying to get it unrooted.
So i have downloaded LG mobile support tool and the drivers, i enter the phone to download mode and nothing happens. i get all the time errors. Also, in the lg mobile support tool, i see a software update. Should i do it? I cant though because the start upgrade button is greyed out, and the "LGD802" sign on the left pane is flushing like its trying to verify my g2. Also, should i wait for like 10 minutes or so when i enter download mode for the bar seen at the phone to be completed before the whole process? Lastly, the most of times the lg mobile support tool crashes on the pc.
Please help me folks... :/
the problem is when i hook my phone up the pc and it recognizes it, it starts the download drivers part but it freezes and force closes...

PC doesn't recognize my LG (download mode)

Hey guys!!!
Can you please help me with this?
Yesterday i tried to install a new ROM on my LG Android phone (My LG phone is not working properly, it has a reboot loop). I tried to do a factory reset without success -> the dead Android logo appeared :/
I put my phone in Download Mode and connected to the pc but Windows does not recognize my phone.. it says: "USB device not recognized.. the last USB device you connected to this computer malfunctioned and Windows does not recognize it"
I do not know what to do now.. when i try to flash a ROM with the LG Flash Tool it fails because LG program does not recognize my device..
PS: LG Support Tool recognizes my phone (it shows the model) but i cannot flash a ROM
Thanks!!:fingers-crossed:

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!
