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?
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.

Hello i need help please.
I was trying to flash twrp using adb and fastboot when i accidentally flash aboot.img into system and now it wont boot into the system and it stuck on lg logo and it wont let me boot into recovery mode. When i do the Vol. down + power it directs me to factory data reset and I tried resetting it and gave me an error "Your device is corrupt. It can't be trusted and may not work properly."
Does anybody know how to fix this issue please?.
