[Q] Stuck on Fastboot (Unable to go to download mode) - G2 Q&A, Help & Troubleshooting

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.

Hi
I have an international version 802 version with ROM of g.lewarne inside (rooted)
I've received and accepted the new OTA upgrade, and now i'm stick in the Clockworckmod Recovery.
I've flashed my LG back to the g.lewarne ROM but each time i restart my phone it goes directly to the CWM recovery Mode.
Any suggestion of what to do to get my phone starting normally?

It doesn't go to download mode.
What you need to do to fix this
If you´re stuck in CWM you CAN´T enter in download mode...in this case you have one Option.
download a T/zip file WRP Recovery
and
Plug the usb cable to a computer and enter in cwm recovery
next
adb push "name of recovery".zip /sdcard
next
install the new recovery
open a terminal commando and put this:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
Reboot
If you´re stuck in TWRP you have 2 options.
Enter in download mode and restore the firmware from LGMobile or from ADB command to restore your boot.
sorry for bad english
the same here...
I now have the stable version of Cyanogen tested install.
Supposedly he is fertig.Als Note is only: Checking if loki - fying is needed, Updating partition details ...
Otherwise Zip Install Complete
After the wipe reboot and again in TWRP.
In the file manager of TWRP is not to be understood that an installation place hätte.Den Downloadmod tried (the button is held down the top of the lens and USB cable plugged in to it) always comes only the LG logo and then again TWRP.
This helped me

I don't have access to download mode. Now i don't have either access to CWM recovery. All i get when i plug it to my PC is LG logo with the error: secure booting error.
Also adb does not detect my device.
Thank you for your answer.
It seems many people have encountered the same problem with the latest fota from LG.
then my phone goes to black screen while still on.
I have this problem ;(
I have only black screen, I can't go to twrp or download mode. I can't do nothing! :<

ATT D800 Fastboot Loop No Recovery No Download Mode

Hello All,
I've been searching for hours. I had rooted my LG G2 weeks ago with no problems. I then un-rooted it and I thought reset it to factory. Today in Target I pulled it out of my pocket to make a call and it was black screened to Fastboot.
I have tried holding down Volume - and Power and entering recovery to reset to factory but it immediately goes to Fastboot loop.
I have tried holding down Volume + while plugging in USB for Download Mode but it immediately goes to Fastboot loop.
I have tried adb commands, error: device not found.
I have tried manually updating the Android drivers through Computer Management and selecting many of the Android Platform Sooner versions. My Win7 PC recognizes the phone as ADB Interface > Andriod Sooner Single ADB Interface in Device Manager.
I have tried this http://forum.xda-developers.com/showthread.php?t=2477595 and flashed both laf.img and I cannot get into Download Mode.
What else can I do? Does anyone have any other ideas?
Thanks for your time!
hey same exact thing just happened to me. i had it rooted from earlier, but ended up keeping the stock rom on my AT&T LG G2 D800. What I think happened was ATT just pushed out an OTA update (not sure about other carriers), supposedly some small 15mb update to prepare for upcoming releases and despite declining the install, the phone of course did it anyways.
No recovery, no download mode, factory reset doesn't do anything.
Thanks AT&T! :good:
Are we completely boned here?

Did anyone figure this out? I am stuck in fastboot mode. I can run fastboot commands, but thats about it.
I can't get to ADB, I can't get to recovery, I can't get to download mode. I reboot the phone and it goes immediately back to fastboot.
I've tried flashing recovery, the laf.img, and even rom's inside fastboot and nothing is seeming to work.

If you can't get adb access with either single sooner or pdanet drivers, you may have to resort to this..
http://forum.xda-developers.com/showthread.php?t=2582142
(actually kind of sounds like fun to me)
if you're stuck in fastboot mode then you can simply use the fastboot commands to write the aboot, sbl1, boot, recovery, laf, rpm, tz and dbi partitions.
you can substitute stock recovery.img for a properly patched twrp/cwm img (renamed recovery). from there you should be able to boot into download mode... custom recovery.. or boot back up.

I found a site that had the backed up D800 .img files. I had to use Ubuntu to write them back to my device.. after like 15hrs of googling/writing on forums, I finally got my device to boot back up! lol..
of course there was a popup saying that my device was suspected of rooting and it won't update.. but who cares, it works now!

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.

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.

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.

[Q] Fastboot mode, no download mode, bricked autorec Videotron LG G2 D801 D801V20E

I've done my homework but haven't found how others fix this issue.
Sucessfully rooted the Videotron LG G2 D801
.
The mistake: Autorec my LG G2 D801 with autorec D801 version unaware that Canadian D801 must be autorec'd by autorec D803 version.
Status of phone: Boots shows LG logo and goes immediately to black screen 'Fastboot mode started'.
Tried: Download mode attempts bring up the download mode logo for a sec and immediately the phone goes back to Fastboot mode started screen.
User rickthewood2 reported he had the same issue and was provided a fix. http://forum.xda-developers.com/showthread.php?t=2723687.
I tracked him on a french forum where he reported that XDA guy compiled a file for him that unbricked this issue as he was having a hard time with entering commands. He also specified that the trick was to repair his download mode with a laf.img file ... once download mode was repaired he went back to stock rom. This is the link of his post made in french http://www.phonandroid.com/forum/ecran-noir-apres-autorec-t90109.html

that is because the download mode partition is broken because it is the wrong model; if you download the correct model of autorec you can use WinRAR/7zip to get the laf.img from the assets folder and then flash it using adb; I know the process to flash the images through fastboot as long as your device is recognized by your pc I can help
a new hope

Very good files Extracted I see the laf I need to use. So are you saying if pc sees the device I can flash using fastboot but if it doesn't I will have to flash via ADB... right? I'm such a newbie.

it's all done using adb; fastboot is the mood you are in and with adb is how we look for device and send the commands
after going into your adb folder(android sdk>platform-tools or ioroot folder) you make sure to copy the laf image into it and then after opening cmd window and cd into the adb folder you use the adb devices command if after starting daemon it show your device in fastboot mode then you do the following:
fastboot erase laf
fastboot flash laf laf.img
actually you can flash all the partitions using fastboot(the images inside assets folder) and then doing a simple reboot should boot your device but if it doesn't then you just have to boot into download mode:
fastboot erase aboot
fastboot flash aboot aboot.img
fastboot erase boot
fastboot flash boot boot.img
fastboot erase laf
fastboot flash laf laf.img
fastboot erase recovery
fastboot flash recovery recovery.img
with either method when done flashing correct files use:
fastboot reboot
and your device will reboot; make sure that you flash all correct files before rebooting and then if device boots normally you will have custom recovery and be back on the stock rom if by any chance it doesn't boot then you can just boot into download mode(hold volume up while plugging in usb cable to phone/pc) and then just kdz/tot back to stock
Best of Luck :fingers-crossed:
Awesome Just Awesome!!

Dude, I read those instructions from all over the net but I guess I needed this divine intervention. You have no idea how greatful I am for your assistance. Current situation: Download mode is back and LGmobile support tool is doing its download thing for stock rom.
I have to add that I was receiving an error message from CMD prompt for command:
fastboot flash laf.img
I replaced that by:
fastboot flash laf laf.img
and was abble to finish the rest.
Good safe rooting to all the rooters!

PS: too bad I can only thank you once on this one...

Glad it all worked out and thanks for pointing that out for some reason I always forget that fastboot needs the partition name before the image name (trust me it isn't first time I make the mistake but we ain't perfect)
If you decide to go at it again make sure to use correct version of autorec and enjoy your device :high-five:

You're not serious right? Tell me you're joking!
With ppl like you around I'm no longer worried. This was a learning experience.
Guess what.... G2 now rooted with correct autorec version... TWRP is enabled and BusyBox is in da house too. Next step... create a backup after deleting all these spying resources hungry LG default apps and then... ENABLE 4K video capture!
Amigo, I told you You just made this dude's week.
By the way if you think I forgot something importand pls advise. I read somewhere it was a good thing to save efs or something.

Hi I've been studying this thread because I have the same problem--used the wrong version of autorec and now my Verizon LG G2 is stuck in fastboot. I've downloaded the correct version of autorec but I do not understand how to open the apk to access the assets file. I right click but get no option to open or extract. Can anyone help me, or direct me to a link where the laf.img files are stored? Thanks!

Thanks, but I took it to a shop that borked it completely. Just sold it on the Bay. Picked up a Moto X off Craig's...lol...oh well, the Moto is pretty cool and since it's running 4.4.4 I can't do anything to it until someone figures out how to unlock the bootloader...probably for the best...

I've done my homework but haven't found how others fix this issue.
Sucessfully rooted the Videotron LG G2 D801
.
The mistake: Autorec my LG G2 D801 with autorec D801 version unaware that Canadian D801 must be autorec'd by autorec D803 version.
Status of phone: Boots shows LG logo and goes immediately to black screen 'Fastboot mode started'.
Tried: Download mode attempts bring up the download mode logo for a sec and immediately the phone goes back to Fastboot mode started screen.
User rickthewood2 reported he had the same issue and was provided a fix. http://forum.xda-developers.com/showthread.php?t=2723687.
I tracked him on a french forum where he reported that XDA guy compiled a file for him that unbricked this issue as he was having a hard time with entering commands. He also specified that the trick was to repair his download mode with a laf.img file ... once download mode was repaired he went back to stock rom. This is the link of his post made in french http://www.phonandroid.com/forum/ecran-noir-apres-autorec-t90109.html

Hi,
do you have an idea wich autorec is nessesary for a G2 shipped from HongKong. Ic guess I have the same issue like you. But on the case I have a D802 lable. So I thought it must be the one for a D802. May I'm wrong?
Now I tried a D800 one and it worked as I could start my phones download mode. After starting it I installed different roms but all had strange behavior like wrong touch an just flipping arround after touching. There is also no chance to connect to the network. Later I saw that my G2 32GB only shows 10GB of internal storage when its connected to pc. Any idea what I did wrong?
I would be very thankfull for help!!!!
Thanks

[Q] Autorec - "Fastboot Mode Started" while flashing recovery

Hi.
I think I should stop and ask for advice before trying anything else.
I have just received a 32gb D802 (International I think) with build KOT49I.D80220b and baseband M8974A-AAAANAZM-1.0.190082
It was pre-rooted. Root worked fine after updating SU binary. I downloaded twrp 2.8.0.1 from within flashify and installed it.
It displayed status 7 during recovery flash. I notice it already had philz touch recovery installed at the time rather than stock recovery.
I then tried D802_AutoRec.apk
On reboot it is stuck in fastboot mode displaying "Fastboot mode started".
I've plugged it in to usb on pc after installing minimal ADB.
What's my next step? I'm worried it may not be charging and I have limited time before it dies?
Edit: To correct sequence of events.

Thank you.
I ran pokreni.bat and all operations appeared to complete successfully
However on reboot following 15 seconds pressing power button it just goes back to fastboot mode
Try powering off the device.
Hold volume up - then connect usb to computer.
Is download mode alive ?
anyway - which package(philz) did you flash anyway ?

It doesn't power off fully it reboots. If I hold (and continue to hold) volume up immediately following exit from fastboot mode it just goes back to fastboot mode.
All I've flashed since receiving the phone is twrp 2.8.0.1 from within Autorec
Edit, sorry I'm wrong. I downloaded 2.8.0.1 from within flashify
I ask because of this: "I notice it already had philz touch recovery installed at the time rather than stock recovery."
Autorec installs 2.7.0.0
So if you downloaded the right version of 2.8.0.1 / 2.8.0.2 it should work (updating = installing from current TWRP - not philz)
EDIT: long hold the power..long long..until it's off ( cable should be disconnected)..then when you're sure it's off - hold volume up and connect to cable and obviously PC.

Philz was already installed when I received the phone but I didnt realize until I tried to flash twrp with flashify.
OK, I can get it to power off completely then when holding volume up and plugging it into USB/PC it briefly enters download mode then goes to fastboot again
EDIT: Should I try this recovery http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705 then renaming it to recovery.img and re-running the .bat file you linked to previously after replacing the recovery.img there with the new one?
Edit2: Just to be clear (I was confusing myself) I did manage to run D802_AutoRec.apk immediately prior to the fastboot problem.
Edit3: I can get it to the factory data reset screen when attempting to enter recovery but it goes back to fastboot after I select Yes twice
Edit4: I have the 32gb D802. Perhaps something from here would help? http://downloads.codefi.re/autoprime/LG/LG_G2/D802/Stock_Firmware and I could fastboot flash the relevant partitions. I dont like the look of 16G Partitions though seeing as I have a 32gb G2.
Is there any more info I can provide? I bought it from http://www.aliexpress.com/item/Orig...uad-core-5-2-inch-Refurbished/2037229256.html where it says it was russian multilanguage although it came setup in English. It does say LG-D802 on the back and packaging just so you know I haven't confused the model.

Done.
Anticpating the next move I have copied them into fastboot.exe folder on PC where I have the following .bat file from earlier
Code:
fastboot erase laf
fastboot flash laf laf.img
fastboot flash boot boot.img
fastboot flash aboot aboot.img
fastboot erase recovery
fastboot flash recovery recovery.img
Should I remove the recovery.img or use another?
Edit: Nail biting
For now remove the recovery. See if you can get dload mode. Remove also the lines mentioning recovery

flashed extracted recovery. No errors. Cant get into recovery or download mode though. Just goes back to fastboot.
bender_007 has been a great help via PM. Thanks. I hope he doesn't mind me asking another question here.
I'm at the stage where I downloaded and installed the recommended kdz rom based on imei number but when I flash it it's Korean and the touch screen registers touches in a different place so it's pretty much unusable.
I'd read that other 32GB D802 roms should be safe to flash so I tried the EE 32GB one from http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/United+Kingdom/ - This one installs but bootloops after a while (kernel panic?) and the touch screen mis-registration issue is still present.
All ideas gratefully received
Oh..btw..I see now it says refurbished. Can you open it up somehow and see if there are other seals ?
Or at least try flashing older firmware and give it on their warranty (if there is any warranty )
