[Q] D801 Stuck In Fastboot Mode

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--

Same problem did you fix it?

Cant boot into download mode (recovery/rom are ok)

Hi guys! From what I understand the phone has 3 modes of boot. Recovery , normal and download mode.
I installed TWRP as recovery . At some point the cellphone only boot to recovery (in all modes) , I fixed it with some adb commands but now I got recovery and normal mode.... My cellphone is fine but Im not able toi install any original rom with the lg tools.
I already tested the key combinations and with apks that have the option to boot to download mode presing a button. Booting to download mode enter TRWP
My device is a d806 AND im on rooted stock 4.4.2.
Any idea how to fix this?
Thanks
Any help ? nobody knows how to restore download mode? :/

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?

H340n Stuck at boot logo, no download mode, no fastboot

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

HELP : ADP mode only detected in recovery not on fastboot

I softbricked my phone. I was in TWRP and wiped everything including the rom that was on it. So i have tried flashing the stock back on using the various toolkits out there. I have also tried to push a rom file onto the sdcard. However it seems my computer is only detecting the phone in adp mode when its in recovery or sometimes when its stuck on the google logo screen. as soon as it goes into fastboot mode no more detection. Also it seems the bootloader is locked again. hwoever i cant unlock it as i cant get it into the adb mode on thr fastloader screen. someone please help. ?
