[Q] D801 Stuck In Fastboot Mode - G2 Q&A, Help & Troubleshooting

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?

[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:

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

(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!

Bootloop problem, no recovery, no download mode (Non rooted and No custom recovery)

Hi, I just bought an LG G2 D802 20B Model a couple days ago, yesterday I wanted to downgrade to 4.2.2 and I ended up bricking the phone.
The phone is non rooted, doesn't have any custom recovery, and not recognized by adb even though i installed all the drivers ( koush drivers, PdaNet, Lg drivers ...)
At first I flashed with .kdz file and it ended in bootloop, I tried to factory reset but it doesnt have any effects with the stock recovery it only shows the green android bot and blue progress bar and then restart in 3 seconds and reboots to lg logo and start looping.. After a restart the download mode didn't work anymore it showed me fastboot error, I searched for the tutorial that actually worked and I flashed with .tot method but there is still bootloop and the download mode is stuck at the image attached. The phone is not recognized by neither windows or ubuntu therefore I can't use adb to fix the partitions.
Can any body provide me with a solution? The phone is still new and it will be a shame if its transformed to a brick in 3 days :crying:​
Hey..hmm i think thats how download mode it is...so did you tried to flash again a firmware?

Thanks for your reply, however the phone is not recognized on windows neither on ubuntu therefore this tutorial can't help ...
I am in the exact same situation.
Mine is a D802 32GB Hong Kong model. I stupidly ran AutoRec which soft-bricked my phone. Managed to get Download Mode working, then flashed 20C and 20B which bootlooped. Then I attempted to flash 10B, which got me into this exact state:
Download Mode not working (only shows "Download Mode", does not go to firmware recovery screen, not detected in Win/Linux)
Factory reset (Power + Vol Down) can go to factory reset screen, after factory reset, still bootloop.
Once in a while, I also get the Android icon which then disappears after a few seconds and goes to LG logo again.
If I plug the phone in and do a factory reset, Windows detects the LGE AndroidNet modem, and Linux will detect cdc_acm USB Abstract Control Model driver. Flash Tool and LG Mobile Support seems to detect the phone and attempt to flash, but the phone restarts after a short while.
I have no idea what else to do

[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.

LG G2 Hard Bricked

So I wiped the system partition on my LG G2/D800 (mostly out of stupidity) and now I'm stuck in the boot loop.
Symptoms are following:
1. Stuck in the boot loop
2. Will not go into download or recovery mode
3. When turning on the LG logo appears and disappears repeatedly
4. Device is not detected when plugged into the USB
5. Factory reset using VolDown+Power doesn't do anything
I've tried most of the ideas I've been able to find on the forum, but it looks like I'm stuck mostly because I cannot enter download mode and the phone is not detected in any way when plugged into the USB (no many partitions or anything).
Will be grateful for any ideas how to get out of it?

so vol up and then plug usb, does not take you to download mode?
if not try using srk tools.. if that doesnt work i think you need to short circuit your motherboard.

Indeed I cannot enter download mode with vol up then plug usb.
Good news is that I was able to enter qhsusb mode by short circuiting the moterboard. I used srktools to unbrick in qhsusb mode, however it didn't work. The linked guide recommends to flash only laf.img, aboot.img and boot.img. I don't really understand how flashing more can hurt. I also don't completely understand why flashing these should help. After all, I messed only with the system partition. I'll try to follow the guide more closely, but I'm thinking that a better idea would be to flash system partition in a qhsusb mode. I just need to figure out where to get system.img from.

So now I can consistently get into ghsusb mode by short curcuiting the motherboard, and I can flash img files with dd. I flashed every partition from the stock FW which was on my phone. Now when hold vol up and plug in usb, I'm ending up in a stock recovery. However, I still cannot enter download mode and the phone still suffers from boot loop if I choose to reboot the phone.
