[Q] Download mode stuck - G2 Q&A, Help & Troubleshooting

Hi guys,
Long-time phone rooter/XDA reader, first time posting.
It seems I have finally come across a problem I can't fix by insane amounts of googling and trial&error.
I am currently on some Kitkat custom ROM variant with CWM 6.0.4.4
I'm looking to get back to stock, but my download mode refuses to open. Its stuck at the blue dots screen. (attached picture for clarity)
I've let it sit there overnight, with no change.
I've attempted to use the LGMobile Tool (even this method), but when it reboots my phone, the phone sits on the "LG" screen, and the LG tool eventually errors out ("communication error").
Recently, I managed to back myself into a corner after (incredibly idiotically) accepting an OWA, when my recovery was corrupt, and my download mode would not even open then - and i had to use some bizarre method of commands in Linux to be able to get TWRP on, then flashed CWM and them my ROM.
So what can I do now? I'm assuming my download mode is corrupt - is there a way to flash a good download mode onto the phone?
Any thoughts/input greatly appreciated.
edit:
Ok looks like I have understimated myself.
I used THIS tool to extract my KDZ, to get the LAF file (then renamed it to laf.img)
I then used the instructions from HERE to flash to the correct place.
It did not reboot into download like the thread said it would, but I did a manual download mode entry (while off, hold Volume Up + insert USB) and viola!

Hey thanks for the post. My download mode will not go past the 5 blue dots screen. I am trying to return to stock but I get the same download mode error. I am rooted and have TWRP installed. This download mode error has happened before. I fixed it by flashing CM and then going into download mode and it worked! But my TWRP is getting an error when installing any rom. It fails and installation and says error executing updater binary. I just need to fix download mode or TWRP. Any help would be great.

Did you already have recovery installed when you were stuck at the 5 dots download mode screen?

How to Connect in ADB ?

My phone is also stucked same as yours, How you connect your phone is adb mode. My Phone just show download stuck screen and have no recovery. Any help would be really appreciated.

LG G2 D801 unable to get to download mode

I recently put TWRP on my LG G2 from Tmobile (D801). I then used it to flash CyanogenMod 10.2. It worked great. Then I decided to see if any other ROMS were available.
I downloaded AEON v3.zip (which I now realize was for D800) and tried to flash it from TWRP. It (obviously) didn't work as I expected, and now I can't get the phone into recovery mode. When I try to get it into the download mode (volume up+plugging in USB), the download mode screen flashes up for a second, but then it just goes to the Fastboot mode started /udc_start() screen.
It appears that I can use the fastboot utility on my computer to interact with the phone. fastboot devices -l results in a question mark (it says "? fastboot").
I've tried downloading openrecovery-twrp-2.6.3.2-g2tmo.img and flashing it to my device with:
fastboot flash recovery openrecovery-twrp-2.6.3.2-g2tmo.img
It indicates that it is successful ("OK") but I still cannot get into recovery mode.
Help?
Try downloading an app from The Play store called Quick Boot, it should let you reboot into recovery. Also, I'd imagine CM has a feature that allows you to boot into recovery from the power menu when you hold your power button down for a sec.
Sent from CAMACHO, my Verizon G2 (VS980) running PAC ROM.
solved
Thanks for the reply! I didn't have a working ROM to boot into, so I was just trying to get into Recovery mode to begin with.
Got some help from autoprime on #lg-g2 and found out that I was using the wrong timing on my recovery mode key presses to get into TWRP.

[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
-says when booting

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] Ruined Fastboot mode, but regular boot works?

Okay, so not sure what I did here.
I have an LG G2 ATT version with 4.2.2 installed.
I was trying to install CM, which I already have on my Nexus 7 and love. But the LG G2 doesn't have a nice one-click install app like the Nexus 7 does.
So, I managed to root it, and got SuperUser installed and Clockworkrecoverymod.
At one point I also had TWRP installed, and I think that is where I went wrong. I went to flash a new fastboot / recovery mode and think I selected the wrong one (LG G2 International).
Ever since then, attempting to reboot into recovery using the hardware method (volume down + power) doesn't work. If i force it into fastboot mode using Clockworkrecoverymod or ioroot, I get a strange message.
All the phone shows is white text on a black background:
[830] Fastboot mode started
[940] -- rest --
[950] fastboot; processing commands
then, if i unplug the USB port, I get a few messages. If I replug it in, I get the above message again, with different time stamps.
If I boot normally, it pulls up the normal stock OS, but any attempt to boot into fast mode gets me this message. I can also boot into download mode, but it hangs at 0 %. I tried Flashing a new Recovery using clockworkmod, and it says it worked, but booting into recovery just results in ending up in the same Fastboot mode deadend.
I see the same message if I try to factory reset the phone through the normal software method in options.
So, it is great that I didn't completely brick my phone when I idiotically installed for the wrong mode, but without being able to get into fastboot mode, what are my options for getting back on there and back to stock so I can try again?
And yes, I tried to make a backup on my device, but when I went to go back to it, clockworkmod said it isn't there. Not sure how I messed that up, but anyone have any suggestions on what I can do going forward?
As I understand; If you're trying to boot it to recovery mode, it goes to fastboot mode, right?
If I understood right; you need just flash recovery to your device.
G2 has a different boot process from other devices. If bootloader failed to boot the thing you want to boot, it goes to fastboot mode. That's why it goes fastboot mode when you try to boot it to recovery.
Ah yeah, i just couldn't figure out how to get it out of Fastmode. I was a little confused about the difference between fastmode and recovery.
I seemed to have fixed the problem by AutoRec, for whatever that is worth. Now it boots into TWRP's recovery mode. Shouldn't be hard to get cyanogenmod now.

d801 boots to cm13 but no recovery and no download mode.

I flashed to cm13 nightly 20160302 and my phone boots to cm with no problem but now I am unable to boot into recovery through any method with twrp 3.0.0.4 or any twrp version I tried inside of twrp manager or flashify, I am put into fastboot mode when trying to enter recovery with 3.0.0.4 and a few other I tried while other versions give me unsecured boot message. When trying to go into download mode I get the first download mode screen and then the screen goes blank and brings up 15 system partitions on my pc with only one partition containing a folder called image with a bunch of files. The phone is detectable through adb and as a storage device on my pc while booted into cm and while in fastboot mode the phone shows up as marshal london device- marshal london bootloader interface in device manager with no storage.
I planned on going to cloudyg2 but now I'm thinking about just going back to stock, would I be able to use the lg flash tool to get back to stock? Or possibly use adb recover to stock or use adb sideload to flash the default lg rom?

Flashing Recovery Post Hard Brick

Hey,
I hard bricked my phone, the one where you connect to the PC 15 or so drives open up (no download mode, no recovery and no fastboot) and then managed to fix it (VIA SRK Tool which flashed a stock recovery instead of a custom one) and got download mode back.
KDZ Method isn't working, it keeps saying I need to restart my device 2%.
So is there any way of flashing the TWRP recovery through the download mode or at the very least any way to extract my data (only a few folders) through the download mode?
I don't know why but no one seems to notice this thread
Thanks a lot, any help will be much appreciated.
PS: Please ask if any further information is required
(I have a D801, I can get to download mode, factory reset screen and LG logo which then leads to the "Security error" coz there is no firmware in the phone.)
