Hey guys, my LG Gt540 i dusted off the old shelf got turned on, I had previously added some recovery mod off my memory but thats it. Anyway, when I turn it on, it just stays there with a screen saying "fastboot mode" I can also get it to download mode. This still occurs when the sim and sd card are taken out. Any help is appreciated.
MicroAndroidPack. CMD console, fastboot drivers. Connect to PC in fastboot mode , if Windows will found your fastboot device, go to CMD console and write:
fastboot reboot
Now your LG should booted normaly.
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?

Follow this thread, I tried the TWRP terminal code and it worked. Let me know how it goes
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..

(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!
im onthe verizon variant and stuff like this just annoys me to no end you say no lg pushes it to your device anyway its wrong not even samsung stoops this low i am glad i have a custom rom

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.

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:

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!
Kybby
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...

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

Thanks alot it worked for me but my phone is stuck in download mode whilst installing firmware at %60 every time saying the phone is disconnected from pc ... any idea please
Thanks in adv
So I have read alot about this problem and not one can help me fix my phone.
I got an lg g d802t Australian version I cannot acces anything Lg screen pops up and striaght to fastboot mode... iv tried posting on the other help thread but i need this fixed asap.... and no1 has replied to my post so im making a thread.
Iv tried using fastboot cmd command or w/e but it gets stuck at waiting for device. tried downloading the driver for fastboot still happens. Iv tryd almost everything out there and yet i cant find what im doing wrong. following intrustions one by one and somehow i still cant get it working.
All the does is power on, logo comes up and boom fastboot mode. No recovery mode no hold down and power button nothing happens.
when connected to usb i hear a ding and my phone comes up with -reset- -portcharge- about 3times and then nothing.
download google adb driver, select it from the list - you can select nexus..
then "fastboot devices"
then you would need your partitions, aboot, boot, laf from the same compilation to proceed.

Hi guys, im already hopeless but i'm here to beg for your experience.
I got a G2 D805, the screen broke, then i replaced with a new one. But, when it powered on gave the message that it was going to turn off. The battery icon was with an X.
Soooo... i thought, ok the battery is gone. Bought another one. Nope, it wasnt the battery.
Then I tried the "factory reset". As soon as it starts, it restarts, loads the welcome screen(where you first customize the phone), 1 second and it gives the power off message.
Tried the recovery mode. Same.
Download mode? Ok, i read something about the kdz recovery. The LG Flash Tool cant see the phone. Neither the pc. Doesnt make a sound when i connect it on download mode.
Then tried the "fastboot mode" thingy where you press something against a single chip part inside the phone until it makes fastboot avaiable. On fastboot, thought it was finally going to work. The device even appeared on the pc. Tried those below with drivers from: "universal adb drivers", "pdanet", "android sdk", even some "15 adb install" drivers. No results.
I typed "fastboot devices" = ? fastboot
I typed "fastboot erase recovery" = failure sending erase group start command to the card (on pc remote: failed to erase partition)
I typed "fastboot continue" = failure sending read command to the card AND failure setting read block count for card AND cannot read boot image header
"adb devices" = list of devices attached (nothing, just that)
Im close to losing my mind here. Any help is appreciated.
Thanks for your time.
