My LG G3 got stuck after OTA update, no recovery mode. Only fastboot and ADB. fastboot is unable to flash to any of the partitions, it reports invalid data.
really just need a gpt.bin file for the lg g3. im quite advanced, expert advice would be gratefully appreciated.
maybe a command?
My recovery is not working but i do have a workaround to get into adb. Does anyone know any command thatbi can execute from the terminal/command prompt that would send my g3 to adb sideload?
I think mybootloader of partition table might be messed up.
P.s
No download mode
No recovery
Workaround fastboot mode - unable to flash anything
Workaround adb mode -

Hi guys,
So my lg g3 was running on cyanogen 13.0 and then i updated to one nightly which was not so good (freezing all the time).. i tried to rollback but somehow I ended up with my phone bricked..
I cannot go into twrp, i just see the fastboot console. I am able to execute some commands from my computer but even tough i installed the device drivers from lg's website i cannot get the phone recognised by the adb.
it's weird because i can execute fastboot reboot, but i cannot execute fastboot pull /media.
Can someone please point me to a solution in order to recover my data and be able to go into recovery mode.
Thanks in advance.
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.

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 ?
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

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
Hey guys, I think I may have permanently bricked my device :/ As it is a H810 there is no recovery available so I can only enter download-mode and fast-boot mode. Basically I accidentally flashed the wrong files
dd if=/sdcard/modemst1.img of=/dev/zero of=/dev/block/mmcblk0p24
dd if=/sdcard/modemst2.img of=/dev/zero of=/dev/block/mmcblk0p25
dd if=/sdcard/modemst3.img of=/dev/zero of=/dev/block/mmcblk0p26
as I transferred the incorrect backed-up files from my computer (I ended up flashing my friends H815 backed up files by mistake). This meant that the phone was unable to boot and is now stuck in a boot loop. I have tried flashing the partitions using fastboot flash mmcblk0p24 modemstl1.img without success and in download mode the device is not recognised so I cannot perform an adb push/pull command.
Thankfully I do have the correct img files to flash back on my computer but I cannot figure out how to actually transfer them to the device. A side note- LGUP does work successfully to flash a stock TOT file to Lolipop so if that is able to copy the new ROM to the device and flash the system partition there might be a way to transfer the files over. The only problem I can see is there really is no way to unlock the bootloader and as the files are not 'stock' this may not be possible.
If anyone has any ideas that would be greatly appreciated. Cheers.
But if LGUP is working for you, why dont you use the option to "upgrade" the phone to the version of the ROM you were using ?
My lg g4 h810 is stuck in fastboot mode not recovery mode not downloading please any one have any idea
I managed to corrupt fastboot mode when trying to boot a twrp image using the command "fastboot boot trwp.img". This made a strange error "FAILED (command write failed (Success))" show up in the terminal. I'm still able to boot in lineage but fastboot mode is rebooting the phone as soon as I enter in that mode. Not sure what to do with this, most thread use fastboot for troubleshooting.
I'm reading about qpst / qfil... or any guides I see. but I'm thinking I might make it worst so I'm kind of stuck now
Edit:
Well. fixed it with this guide
