I had a near-brick experience today, managed to get it mostly solved.
Working:
Boots to system, call, text, wifi
ZVC radio [came stock with ZVA] and Optimus DE rom
TWRP recovery, with ADB
Not working:
Download mode [freezes at the screen that says 'download mode']
fast boot mode? not sure how to get into it
I'd like to flash back to stock, but I messed something up earlier and for most of the day I could only boot into recovery. Managed to get ADB working and flash a working system back on. if I could boot into download mode, or fastboot mode to fix download mode, I think I'd be alright, but I don't know how with the tools I have.
EDIT;Fixed network data! I'd still like to fix download mode though

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)

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.

Don't know if it's of any help but check out my post on fixing a hard bricked g2 had a similar problem an was able to get it fxed
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.

Hi,
I tried to install Grola Rom on my phone and unfortunately I think that I may have flashed the ROM for the D802 (I tried to find a faster DL than the FShare link).
My phone is now stuck in Fastboot Mode. I've tried every method to try to get my phone back into regular working condition, but my laptop does not recognize my phone. No matter which driver I install, it shows up as Android in device manager and ADB devices and Fastboot devices shows up nothing.
I was able to get it to boot into download mode for about two seconds before it boots itself back into download mode immediately.
I've tried accessing recovery and download mode, but nothing works.
How would I either get back to recovery or at the very least back to download mode so I can go back to stock?
Thanks,
mjoecarroll
Edit: When I boot up it just says Fastboot Started.
When I plug it in, it says:
--reset--
--portchange--
--reset--
--portchange--
Same problem did you fix it?
Hello!
On my LG Leon 4G LTE H340n there is a problem with booting, it stuckts at LG booting logo. When I try to put it in download mode (volume up and connect usb) it displays security booting error and then black screen showing only.
So I can't get it into download mode, can't boot it, and I tried putting it in fastboot (with volume down and connect usb), but that fastboot mode doesn't really work it gives failed command not found on every command.
So how is it possible to reflash the stock recovery (to allow download mode) and then the ROM?
I already have the needed .img files (laf.img, recovery.img, etc..)
I read on other threads that it is possible to write those img files to the correct partition but you need to short testpoint. So how to do this on this phone?
Thanks in advance!
To me the time that I came out this error was installing a Custom Recovery and could not fix it I had to send it to sat and I made a change of motherboard do not know if there will be someone alla able to fix it but I think since you can not access the fastboot or the dowloads mode. Sorry for my English but this translated with google translator
I never need to enter into download mode in my lgms345 to flash a kdz file and all occurred fine!
Lg flash tool put the phone automatically into download mode but your phone need to. Stay connected to your PC
So I was installing twrp and everything went right until it didnt boot to the recovery and from then it keeps booting to lg logo and bootloader warning forever.
I know I can install the stock rom with lg up by I cannot enter download mode since the phone isnt technically turned off. Does anyoene have a solution.
It's my main phone and I literally cannot afford a phone right now.
A way to turn it off would be the solution. Battery was around 70% so it will take a long time to actually have 0%.
Update: I got to the fasboot menu from where I can run fastboot reboot recovery after installing twrp again. Now I have some mounting issues and I cannot flash any zip without entering bootloop. Im trying to use the shut down menu of twrp to try to enter download mode.
2nd Update: solved using lg up with the latest android version.
