I have an LG G2 AT&T D800.
After I rooted my phone successfully, I also flash a custom recovery successfully.
After I did that, I wipe out my data / cache.
And i tried to install a ROM and Google Apps.
I rebooted my phone and I'm stuck with " Fast boot mode started "
I had download mode working but i accidentally made it stop working after i did CMS88168 steps from this page.
http://forum.xda-developers.com/showthread.php?t=2477595
Now I don't have my download mode starting to work and I have no clue on how to fix my phone.
Please help.

Look here
It's for the F320 variants but there is also a link to search for other variant files.
Also just in case you are unable to do what phoost suggested, what i did was keep tr ying to get into recovery, the lg logo would blink fast, but you just have to keep tr ying, and i finally got it and reflashed my rom and its been fine ever since...i did get scared tho, but my g2 is only 4 days old right now, so i can always return and get another, but just do what i said
help

i got the same problem here when flashing the slimkat.
fastboot is like adb sideload.
when you see the usb command, you need to plug the phone to the PC to sync them.
This happened to me a while back the link in post two is how I solved it. You just need to find the laf.img for your model, put it in the same folder as adb and run the adb commands in the tutorial. You might have to change the directory in cmd prompt to where adb is located. Once the laf is successfully flashed you can boot into download mode and flash the kdz for your model.

I tried this but it starts download mode but then goes to fastboot. I was trying to keep download mode. I used the laf.img in the the link you posted. I'm on verizon lg g2 is that the right laf.img?
***Got it thanks***
In the link above that is for the Korean g2 I believe. If I remember correctly there's a link to other img files in his thread. You might also consider flashing the proper boot.img as well. It was a while ago that this happened so I don't recall exactly but if you flash the Verizon boot.img and laf.img you should be good.

I have the same issue. Flashtool thinks my phone is a D801. It boots normally for a few seconds and keep rebooting. Im Reading, dowloading and trying every method around since yesterday afternoon with no luck. I did replace the .dll you provided but i have a different error now, something like mismatch different files and it shows both files names. I just got this phone from a friend. it shows d801 tmo versión in flashtool so i think he was messing around with any tmo based rom (if exits). So flashtool does not let me flash the phone because of this(Think this is a 801 tmo)
I also tried lg suppor tool but it never download the firmware. It get stuck on downloading firmware or checking phone settings (something like that), I found my cell model on the back on the phone so im pretty sure is a SL980. So what comboof files i can use? Do i still can use the.dll provided? Do i have to rename something?(btw...i did and didnt work).
Any other tip? Did i miss something? I have no phone now so im kinda desperate. Thanks in advance for any help.
Sorry for any mistake, english is not my first language.
I will try ti explain you later what i did to fix this issue
Cant you go in fastboot mode?

ok this is what i did to unbrick my phone in your same conditions, in some steps maybe i made some mistakes but i went to the fastboot mode and there i replaced all kernel files of ls980 to fix the issue:
first you have to proceed to back to stock your phone with the T-Mobile USA D80110C_1.kdz :
http://forum.xda-developers.com/showthread.php?t=2432476
now your phone is a full d801, it will boot the system but will be unstable, you must be fast to go to make the developer options and debug your phone, make it on plane and and charging mode, maybe you will be able to do it after some reboots, u must insist.
download the ioroot11 program to root your device, remember always that is unstable, your device will be recognized for not long time, so you have to open the ioroot program often until it recognize your device and root it with the program.
after this step, if your phone is rooted but is still too much ustable to use the adb command (i tried to sideload and push the recovery but it always made me a sideload error), download this program:
http://forum.xda-developers.com/showthread.php?t=2633941
is a simple tool to flash the recovery, it worked in my case, you have to install the recovery of the d801, in my case the philz recovery worked, if everything will be right, you will flash the recovery.
When i was inside the recovery i tried to flash the justin sprint t mobile through the sideload command but it didn't work, same with cm11, i flashed the ls980twrp.zip and when i tried to go to recovery again i was in fastboot.
from fastboot i used the command fastboot erase to erase the partitions: aboot, boot, dbi,laf,misc, persist, recovery, rpm, sbl1, tz.
to erase you must use the command fastboot erase aboot aboot for example, to erase the boot you must repeat boot(fastboot erase boot boot) and so on.
after erased all files i flashed the partitions of ls980:
http://downloads.codefi.re/autoprime/LG/LG_G2/LS980/Stock_Firmware/zv7_partitions
cmd fastboot flash aboot aboot and so on, (i didn't flashed the primaryGPT).
when i flashed all these files i pushed power volume+ and i was in upgrade firmware, so i went back to stock with zv7tot and dll..
it wasn't simple to find a way to back to stock, i guess to made some mistakes but i fixed my issue in this way, i am responsible of what i do with my phone, i cannot guarantee the same results with the others

if you can go to twrp you can flash with adb, i wasn't able to go in recovery, just download with the d801 firmware, that explains why it was complicated
Thanks for all your help. I was able to erase everything via fastboot and my phone fell down and power off before flashing img and now is dead. I have a big blue pitbull inside the house who makes the disaster.,.lol. i just got one white from a friend for $160. Im sure this thread can help any people with a brick device. Thanks again.

but i get no adb?
what ToledoG28 said is exactly what I have been attempting to do to correct this issue but I am facing an additional issue. I had got to the point where I am running the d800 version on my ls980 and it is unstable as you said. I believed I had found a way out but when I connect to the computer no matter what I do I get no adb for no reason as far as I can tell.
makes no sense at all to me as I had adb before all this perfectly fine.

you gotta go do device drivers and your device will show up as some unknown device so you install the adb devices for your phone and then you should get adb to show.

As said, the device does not leave the screen of the leeco, does not start in recovery and fastboot mode. So there is no way I can restore using TWRP. The device is recognized only by the qualcom tool. I need a guide on how to use it. Anyway, thank you for your time.

Try to boot into fastboot from ADB and install a new twrp
Greetings, I tried flashing my LG H440F to its original state via LG Flash Tool.
At the time being it was stuck on 1% and after several errors I desisted and tried another KDZ to flash with same result (stuck at 1%)
Now the phone is stuck in fastboot, I can't boot it to Download mode neither do a Hard Reset as it does nothing.
Adb does not recognize the device and fastboot always throws a FAILED (remote: unknown command) when trying to do anything.
Did I just entirely brick my phone?
Best regards.
No one?

Try to post it in general thread. Maybe someone there will look into it. Btw, fastboot is disabled on lg spirit, so any fastboot command won't work on it.

so unfortunately this phone has no fastboot command except unlock or relock bootloader
i hope you don't have recent 20g firmware. If that so, you can install LG Bridge to update your phone to latest OS (I believe laf/download mode will restored) then try to root again carefully.
if you already using latest 20g firmware then wait untill T-mobile release new update so you can update it via LG bridge

lg flash tool is outdated version of lgup. be patient, i believe t-mobile will release G6's Pie update soon or later. I can't help any further now, sorry man.
Relax, you can still use your phone right? just stay out of root dependent apps and find another alternatives :cheers

Some custom rom has built in root which can activated in setting app (possibly inside developer menu) good luck for that.
