Cannot get into download mode, only fastboot mode - G2 Q&A, Help & Troubleshooting

Before posting this, I tried looking up relevant posts but got nowhere.
I am trying to return my Verizon LG G2 to stock and am following the instructions from this thread to do so: http://forum.xda-developers.com/showthread.php?t=2432476
I am needing to enter download mode to start the process but my phone keeps going into fastboot mode causing for my device to never be recognized to be flashed.
I could use any suggestions at this point to get this to work. Thanks.

See if this thread is of any help getting download mode back, using fastboot commands w/ adb...

[Q] LG G2 ATT D800 stuck in boot loop

I recently got an lg g2 and rooted it, but it would never boot into recovery mode correctly. Well one night i was trying different chargers because it kept saying it was charging and would vibrate and say it was charging again, i woke up and the screen was lit but wasnt booting. I tried to restart it, no affect, tried to recover it, when it does this it goes into the blank screen again and does nothing, it also wont go into download mode. when plugging into the computer around 15 drives pop up and say they need formatting and it says that is is some qual disk drive and wont install any drivers. tried adb and the phone isnt recognized. am I SOL? What else can i try. One disk drive mounts and has a folder named image.
Short version
-wont boot
-no download mode
-recovery does nothing
-computer does not recognize as phone
-comes up with 15 disk drives that needs to be formatted
-one has a folder named image with stuff in it
-adb wont recognize phone
-tried the lg recovery tool and b/c no download mode it will not read the phone (tried to force install the drivers of the phone to see if it would work to no prevail)
Help :crying:

-will not boot
-can get into twrp now

Why not just go back to STOCK?
-for download mode, dont try to BOOT into download mode. Use the method of holding VOL UP while plugging in USB when the Flashtools are ready to go with the TOT and DLL files.

Did this already, didn't repair it, said device does not have enough space during the last step. it allowed it to go into download mode for a second, but will not stay in it.
Solved my problem, will post a guide for others this weekend with the same issue.

(Q) Bricked D801, stuck at LG logo, download mode stuck on blue dots, no fastboot

Recently used autorec to install TWRP on my rooted G2 and it booted me into fastboot mode.
i was stuck there and download mode was not working either. It just kept boothing me back to fastboot mode.
So what i did was i flashed a laf.img file via fastboot and download mode came back but not fully. It was not showing the USB symbol, only the words download mode with some blue dots.
I found another thread that said to flash some .img files to the phone via fastboot and i did so.
Now the phone is just stuck on the LG symbol and the computer doesnt recognize it. I've tried everything on these forums and I'm at my wits end. Any help would be greatly appreciated!

[Q] LG G2[d802] bricked. No download, recovery mode. No fastboot

Need urgent help. Accidentally bricked my lg g2 and cannot do anything.. Have searched for help almost 6 hours straight.. The main problem is that i can't enter download mode and recovery mode. When booting phone only lg g2 logo shows up with security error. Computer doesn't recognize phone also, so i cant use adb sideload and so on. My lg was rooted but i didnt have any custom recovery . Please help.
What happened? What did you flash?

Stuck in Fastboot ls980 4.4.2

Phone was stock 4.4.2 from sprint. I did root the phone. The thread said the auto tool would install recovery so I did not install it beforehand.
I ran OneClick_ROOT_RECOVERY as described in a thread on the Xdaforum by accident. It says for d802 only; my phone is the ls980 sprint. Didn't notice d802 at the top of the thread. Phone is now stuck in fastboot and reboots into fastboot. Phone does respond to fastboot commands from command prompt. Phone was running 4.4.2.
I installed openrecovery-twrp-2.8.5.0-ls980 from fastboot hoping if I rebooted it would launch into twrp. It just keeps rebooting into fastboot.
Tried LG flashtool, can't get phone into download mode. It goes into download briefly, then immediately goes into fastboot. Tried using lg flash tool, can't because phone will not stay in download mode..
Tried factory reset mode, it fails with 'certificate error'.
I'm totally stuck.
There are some repair services on eBay that I have used when I bricked my phone it cost about $15-20.

VS980 (No Fasboot, No Recovery, Download mode OK, Greyish-black screen)

Hey guys, I have a VS980 that was wrongly flashed with the wrong variant of CloudyG2 3.3, causing it to boot to Fastboot mode only. I used guides available on these forums that said I needed to flash the laf.img partition back to the phone to get it out of Fastboot mode but it now went back to Fastboot mode with a greyish-black screen, it did not even show the LG logo. I know it went to Fastboot mode because running the the "fastboot devices" command returned the phone identity. I then used SRKtook 2.1 to fix the Recovery, and this led to the phone going into QHSUSB 9006 mode. I then used the same SRKtool 2.1 to fix the QHSUSB 9006 issue. The tool successfully completed the process and even prompted me to flash the stock firmware, which I did using LGFlashTool 1.8, and one of the available TOT files (V26A). The flashing process completed successfully with a PASS. The phone powered on okay but with the same greyish-black screen as from before. I know the flashing process completed successfully because the the phone charges okay, the touchscreen works (even with the greyish-black screen I can unlock the screen, I can press the Home, Recents, and Back virtual buttons), and calls made to the SIM card inside the phone will ring). The PC recognizes the phone in MTP mode with Device Manager reporting it as being an LGE MTP Android Device, sometimes as a LG VS980 4G. My issues are these:
- What is it with the greyish-black screen? Anything I can do to rectify it? By the way it is not an LCD issue because I have repeatedly swapped screens from my other LS980 to the VS980 and from the VS980 to the LS980. On the LS980 both LCDs work perfectly.
- I can't get into Recovery mode. All the normal Volume Down+Power combo does is power on the phone. What can I do?
- I can't get into Fastboot mode. What can I do?
I am in the process of downloading every VS980 stock firmware I can find (10B, 11A, 26A, 39A, 24A, 27A). I will flash each to the phone, hopefully there'll be one that will fix my phone.
