Stuck with Fastboot , now stuck in Recovery with no adb

I Have an LG G2 - Sprint phone the LS980 , been experimenting with it lately , however the last experiment went all wrong
I flashed the stock Rom of the Indian version KDZ file using the LG 2014 Flash tool, I was able to boot but Obviously there were a lot of issues using the OS . However on the next reboot I was stuck in a fastboot loop.
While in the fastboot loop , I was able to erase all partitions one by one and flash back these specific to the ZVC firmware http://downloads.codefi.re/autoprime/LG/LG_G2/LS980/Stock_Firmware/zvc_partitions/
Now I only have Recovery mode and even though I have recovery mode , I cannot adb sideload a file as the system keeps saying it cannot detect a device !
I also tried the Download mode , I can enter the Download mode , but the LG tool will no longer flash it.
Any suggestions ?

Was able to get Download mode going with LG Flash tool , but I now get this error.
ERROR: laf Partition has Changed

LG G3 Bricked / No ADB / No download mode / No recovery

Hi,
Since the rom ( http://forum.xda-developers.com/lg-g3/development/rom-resurrection-remix-lp-v5-5-5-t3198675 ) of my phone crashed. After reboot, the phone is blocked on LG logo. Now, i can't enter in recovery mode (or in the download mode) and when I start my phone, it's fixed on the LG for 5 to 10 minutes, and after that it goes to a terminal (started fastboot mode).
I have read several tutorials to use fastboot to flash the recovery to reinstall a rom, but i have a error when i tried to erase or flash the recovery partition.
I look on my phone, and this error appear : "failed to send erase grp start address".
what can i do to fix this error ?
Thanks.

up please

Use the "boot" command instead of "flash" and it should boot up into recovery or downloadmode, depending on which file you use

I tried but i am stucked on teamwin logo.
Which file do i use for download mode ?

Hard to tell, there are some laf.img files floating around on xda and google or even better, extract the laf.img from the stock kdz depending on your android version (for instance you flashed 6.0 you pick the 30b kdz and extract it with the firmware extraction tool)
I would suggest you to and try to use the boot command with them..
Be carefull, do not use the flash command until you found one that boots into downloadmode properly or you can loose your fastboot mode aswell
From then on you should be able to boot into the downloadmode and flash a new firmware via the lg flashtool

I need help please. What can i do to re install a rom ?

Does your PC recognise the port.?
I found tutorial under bender_007 signature. People seemed happy with tool.

Doesn't hurt to read and ask some questions.

Can you elaborate, how exactly your phone crashed, it is very unlikely that it will mess all the partitions just by crashing the rom?

The rom crushed twice, and now i can not access to recovery to install a new rom. I only have access to the fastboot command. Adb not working.
I tried to boot on recovery.img, but it's not working.
Thank for your help.
Regards,

Help please ?

Today i can connected to my phone with ADB when i tape this fastboot command : fastboot boot ./recovery.img.
I can too go into my phone as root with adb command : adb shell.
i tried to push flash_image on my phone and use it, but it donesn't work.
how can i flash my phone with adb command ?

LG G3 Stuck in a Boot Loop. Someone please help me

I think I bricked my G3 :/
I tried usual methods but couldn't get into recovery or download mode, then a few days ago I realized I could get it into this fastboot mode by holding volume up and plugging into USB as you would normally do to get into download mode but you have to hold up for a minute or so (it shows the download mode icon for a few seconds and then goes to fastboot) when in fastboot it connects to the computer and shows in device manager as "android device" and the phone says "processing commands" So I tried to follow this guide http://forum.xda-developers.com/showthread.php?t=2785089 to return it to stock, but I couldn't get it to show up in the LG software.
I read some forum posts about fastboot mode and found that by using the command "fastboot boot twrp.img" (the recovery image I downloaded) in command prompt it would send it to the phone and the phone would display some info and then reboot into TWRP, from here I tried to install a correct rom but the installation starts and there are some errors and then it hangs. I also tried the command "fastboot flash recovery twrp.img" but it fails. This is as far as I have got with it.
It came to me in this condition but the previous owner said he was running Cyanogen and it was working fine until he tried to update it with a nightly build. I suspect he might've tried to install the wrong rom for the phone or the rom was corrupt.

ou could try to revive the phone doing a testpoint and then use boarddiag tools (look in xda thread).
Here is how to make a testpoint: http://forum.xda-developers.com/showpost.php?p=65002893&postcount=17

That can happen because
1: USB debugging is off on your device
2: Drivers are not installed properly
Proper fixes
1: Turn on usb debugging.
2: Install driver again or try the procedure on some other computer
(If you can get a computer running Windows 7 32-bit that would be a good choice)

im stuck at firmware update. every time i restart my phone theres no download mode and directly go to firmware update. how can i back download mode? i cant open my phone to on the debug setting

Fastboot doesnt work
Hi there
I hardbricked my phone while reinstalling stock rom when my laptop crashed. Afterwards adb and download mode wouldn't start, only thing now is fastboot.
I tried your solution, but it doesn't seems to be working. The device is showing in CMD (fastboot devices) but further commands arent accepted, they show up at the G3 screen, but afterwards nothing happens. What can i do (I really don't want to try the "short-circut - Qualcom" method).
Drivers and so on are properly installed
Thanks in advance

Can't get to download mode!
I did everything as instructed and the flashing was successful...
But whenever I want to go to download mode, it just shows download mode icon and then goes straight to fastboot!
How can I fix this?

Lg G3 D851 10c here, trying this method after trying to flash magisk and got stuck with Fast boot mode. its been stuck on "erasing 'laf' ..." for a very very long time.

thanx..............work perfect lg d851 10c

Hi, Dev /..
Mine is lg ge d851 10f
What Shoud i flash to install recovery and boot into recovery to flash roms. kindly help me ASAP...:fingers-crossed:

hi mine is d85110f . which laf.img shoud i flash kindly help

booting to download mode
in adb type
PHP:
adb reboot bootloader
this should get you to download mode......
if you try
PHP:
adb reboot fastboot
or VOL UP+USB
you cannot enter download mode
if you are on a custom rom.
The phone will just reboot.
However
PHP:
adb reboot bootloader
seems to do the trick.
Also I am on LG G3 D858HK with mokee rom 7.1
and this works for me.

twrp working but unable to mount storage.
download mode showing but its not detect.
fastboot mode not working
tried everything change file system etc

System corrupted, laf removed, fastboot doesnt work, stock recovery is useless.

Alright here's the story. I was trying to put CM on this rooted LP 5.0.1 tmobile d851 (20e i think). I backed up and removed the LAF in order to access fastboot so i could flash the custom recovery. fastboot would send the recovery, but the phone would never actually flash the img to the device and report done. Even "fastboot reboot" did nothing. "fastboot devices" reported the serial as "?" and no driver or Arch/CentOS/other windows installs would get fastboot working. fastboot showed up as Marshal london bootloader in device manager.
So then i tried using flash_image from inside of rooted LP to flash the recovery however i ran into PIE errors that could be fixed by replacing /usr/bin/linker. So I found a patched version, rm -rf the old one and tried to cp in the new one. This seemed like a totally valid idea from my linux experience. Buuuut crap. Nothing works. No commands are accepted because I deleted linker. I rebooted cause I had no better alternative and i get a dead android "no command".... Looks like I found the single best way to kill an android installation.
Now im really stuck because i cant use download mode (LAF) to restore because it has been deleted to access fastboot and fastboot wont actually do anything so I can't restore the laf. There is no custom recovery. The stock recovery adb sideload will only let me install OTAs and far as i know there isn't a FULL OTA that will restore the entire system. I even tried the qualcomm 9008 hard brick method with boardDiag, but that doesnt work on tmobile.
I see a few options:
Somehow get fastboot and then download mode working
Wait for a 6.0 OTA and hope it updates the linker bin
advise?
also, the LG logo appears on screen and the LG serial port (the one used for the LG flasher tool) is present in my device manager for a good 15secs before the no command android shows up. I tried lg flasher tool with this time window but it always cut out before the tool could get anywhere.
Edit: This is what the fastboot process would look like:
Screen right after fastboot boot:
[500] Fastboot mode started
[600] -- reset --
[610] -- portchange --
[710] fastboot: processing commands
fastboot erase aboot brings:
erasing 'aboot' ... on command prompt
and
[346290] fastboot: getvarartition-type:aboot
[346350] fastboot: erase:aboot
after those appear it just hangs like that
unplugging it after that command gives me:
FAILED (status read failed (Too many links))
finished. total time: 164.350s
on cmd
and
[514820] -- reset --
[514820] EP1/out FAIL nfo=40 p0=f90bao0
[514830] -- portchange --
[514840] usb_read(0) transaction failed
[514890] fastboot: oops!
[514940] fastboot: processing commands
Click to expand...
Click to collapse

Did you ever find a fix for this?

No, its either professional jtag, or maybe the MM stock ota update zip will fix it if it includes the linker. i havent found this ota on the Internets yet though.

i just had the same problem. any fixes?

flash laf via fastboot

download laf file for your model and flash it....
"fastboot erase laf" then
"fastboot flash laf laf.img"
"fastboot reboot"
Then try to put your phone into download mode.

I think you have a serious problem
You have to see google fix lg g3 on Qualcomm mode...I mean hard brick fix....
Download as instructed
I think it will be fixed
Recently I fixed lg g3 from only led blink no signal to pc and only vibrate and others

That doesn't work on tmobile G3s, thanks though. I did try it anyways btw.

Getting the update.zip from a friend. its in the SD card but its not showing up in MTP so were trying to figure that out. once i have the zip ill try flashing it. if it doesnt work, itll get a octoplus jtag flash.

Well the update did not like the fact that this phone was missing the linker bin or the previous root because it fails when checking the current system. Looks like octoplus is the only way cause i'm an idiot.
Anyone know where i can send this to get it done? i thought some people on ebay did it but i cant find them.

I have same problem, no download mode, system corrupted and recovery is useless.

If it's a tmobile G3 (d851) you have no choice but send it to someone for an octoplus jtag service because the DIY jtag method doesn't work. Got mine done for $42 after shipping from an ebay service.

Finally I recovered it, I have to short testpoint then connect cable to PC, my device is dual sim therefore different logic board, see this http://forum.xda-developers.com/lg-g3/help/lg-d858-qualcomm-test-location-t3293440 for D856/7/8 testpoint to get device into Qualcomm 9008 mode, then I had flash F400K (yes korean rom) tot from thread http://forum.xda-developers.com/showthread.php?t=2785089 using BoardDiagv2.99 http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359 to get it live and get into download mode.
Now finally flashed stock KDZ using this post http://forum.xda-developers.com/showpost.php?p=64624353&postcount=3
If I knew there is new tool to flash MM stock, I wouldn't brick my device. :silly:

Thats exactly what i tried but didn't work because D851
