Hi,
I am stuck with a LG G3 US990 on download mode. Following is the history:
1. Restored a LG G3 LS990 Nandroid Backup to device.
2. Flashed Cloudy 1.3 in hopes of getting a sim unlock(sim unlock failed - network was still grayed out)
3. Tried to restore phone back to LS990ZV4 stock using fastboot.
4. Accidentally flashed laf and stock recovery.
5. Stock recovery was accessible for a while and the phone showed "Security Error" when trying to do a normal boot.
6. Above later changed to Download Mode. Now, the phone goes to Download Mode if a normal boot is performed. When tried to get to recovery, it shows "Recovery Mode" but still goes to Download Mode.
When I try to restore phone to LS990ZV4 stock using Flash Tool 1.8, I get an Error: Partition Table change 00000064. When I try to flash it back to US99010a stock using LG Flash Tools 2014(I have to do this as US99010a only has kdz), the phone is never detected. I have tried multiple reboots of my PC, changed com ports and everything possible else than using another PC.
I also tried to extract dll and .dz from the kdz to use on Flash Tool 1.8 but that failed with error: Failed in Previous Load ().
On LG Flash Tool 1.8, the phone is detected and progress goes up to 6% before partition table... error is displayed. Phone Model shows as LGLS990 and IMEI,PID info is unknown.
Any help on this would be greatly appreciated and I would recommend anyone trying to get a sim unlock on US990 should definitely refrain at this moment as I have apparently lost a device in this pursuit.
Thanks to @Abu Siona for all his help so far!

try this:
note: that what you are trying to achieve is take the phone into fastboot mode so you can then fastboot flash us990 partition data (laf.bin or laf.img from us990)
plug in the phone thats in download mode
download and extract the attached, change into the extracted folder.
start command prompt in that folder ie
execute ports.bat ( this shows your lg diag amd mdm ports) your diag port i want to assume is com41 (flashtool port)
when in download mode, check your flashtool com port (want to assume is com 41) if not replace appropriately with the right download mode comport. default here is com41
so copy and send this as below (be sure you have the right com port specified):
Send_Command.exe \\.\COM41
this takes you to su (root) and you should have the # sign
then delete the laf file thats causing all the stress by sending the command below:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
with the right port selected after this command it should return #
then reboot phone battery out and in, then power , if all went well you should be back in fastboot mode, then grab the us990 Z4 partition and fastboot flash into phone. you should be good.

Hey,
Thanks a lot for this helpful post! Device now boots in to fastboot mode and though I am able to write most of the files, I am not able to write following files: BackupGPT, rct, PrimaryGPT . The error which I get is "remoteartition table does not exist"
I tried flashing TWRP recovery but instead of going in to recovery the phone goes in to download mode.
Thanks!

You ll need to fastboot flash laf.bin if you open / edit the flash.bat laf.bin was not included I think .. just get back to fastboot mode and fastboot flash laf.bin like:
fastboot flash laf laf.bin
reboot and phone should boot normally and all modes should work.
Thanks

Hey,
Thanks much for your reply. I followed your instructions and was able to boot successfully in to fastboot mode.
I proceeded to flash the partitions including laf.bin but the phone still goes in to download mode. I tried flashing partitions of both US990 and LS990 with same results.
Also, I was not able to flash following partitions from either of US990 or LS990:
rct.bin - Error in fastboot while flashing- remote: size too large
PrimaryGPT.bin - Error in fastboot while flashing- remote: Partition table doesn't exists
BackupGPT.bin - Error in fastboot while flashing- remote: Partition table doesn't exists
From my understanding the Partition Table is broken or actually does not exist at all and hence I can not write the OS, I might be incorrect though. I need to figure out how to re-build partition table or broken partition on LG G3.
Any help would be greatly appreciated.

Sometimes the solution is simple and the brain just won't think in the right direction. I was finally able to restore my US990 back to US990(it got converted in to LS990). The solution is to flash TWRP in fastboot and restore the nandroid backup. MAKE SURE YOU HAVE A NANDROID BACKUP before you get in to the conversion business.
Thanks a ton to @essojay

I can only confirm once I'm able to achieve the unlock. I have now flashed Cloudy 1.3 on the phone again and it's a LS990 now. The Bluetooth and MAC addresses are unavailable and there is no network. I'm thinking what to do next.

US990 Bands: LTE B1/B3/B17/B18/B26/B41, WCDMA B1/B2/B5, GSM 900/1800/1900, CDMA BC0/BC6
@Abu Siona
I cannot register on Rogers in Canada apparently because it operates on 850but the phone reads my sim card and also is displaying the phone number.
My device is converted to a LG G3 LS990 and is running Cloudy G3 1.2 . I used shortcut master lite to change the bands. No luck with GSM, can't confirm CDMA functionality. Will be back down south in a few weeks and will then test if this phone works with T-Mobil or any other operator in States.
No download no fastboot
I'm getting emojis and a black screen.. no download mode and no fastboot.. Any ideas would be greatly appreciated, possibly a command to write the new laf.bin , img or boot/recovery img files?

Hi, my sister have a LG G3 16GB phone.
One day the phone restarted it self and since then, it stuck on the LG logo.
So i searched the web (mostly here on XDA) and i found this guide: how to unroot lg g3 all variants.
So i started following it and the fist step is to enter download mode, BUT, when i tried i got to this screen:
[106040]fastboot mode started
[106280]-reset-
[106280]-portchange-
[106320]-reset-
[106330]-portchange-
Click to expand...
Click to collapse
So i went back to searching the web for solution and i found these guide: Tutorial| Fixing "Fastboot mode started".
But i don't have the LAF file of my sister or phone don't even know what android version she had so i found these software: [TOOL] KDZ and TOT Extractor but when I open it, it's all empty and i don't know how to use it.
p.s to enter the download mode (fastboot mod) it's taking something like 3 minutes until something other then the LG logo show up. And it's not the cable or the USB port because i have LG G3 32GB and i enter the download mode with no problem.
Does it still boot normally?
No, stuck on the LG logo.
What phone model?
All I know is that its a 16gb d855. It's bought in Israel so I guess that it's a European version

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.
http://www.androidbrick.com/unbrick-recover-your-dead-lg-g3-g2-all-variants/
Doesn't hurt to read and ask some questions.
no i can't connect my phone with port. I think, i nned to correct the error with fastboot. (remote : failed to erase partition)

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

[514890] fastboot: oops!

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?

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.

anyone can help me please?:crying:

You have triggered the downgrade QFUSE. There is nothing you can do apart from trying to unbrick it like it was dead, but that's not guaranteed to work. You should have researched more before attempting this. My prototype doesn't have a QFUSE, so i am free to downgrade via TOT to kitkat or lollipop.

I second you on this. I just uninstalled MultiROM and got the secure booting error. Depending on the ROM you have, find a bumped kernel and flash it. Most of the kernels on XDA are pre-bumped unless the developer states so. Boot into recovery, tutorials on the internet, then flash the kernel and voila.
if you can use twrp or you're able to flash, use mr_bump.zip: https://mega.nz/#!DNwhRBrK!Ki6zIzXca0KjPShi6L2oaCYIr0CkmH8sEymEt-0Q3ys

=> no download mode available so no possibility to flash manually twrp file from an LG Flash Tool
==> so setup an adb connexion to the phone, cp command to copy the img file on the sdcard or where you want
=> command: "flash recovery twrp-2.8.x.x-xxx.img" (https://www.xda-developers.com/how-to-install-twrp/
=> if it's as worked, you could reboot manually in twrp, make again the partitions if needed and flash any ROM.
Hi and thanks for reading--
I followed this guide for my new LG820UMBK Verizon Unlocked:
Guide LG G8/G8x/v50 Bootloader Unlock and Magisk Root using Firehose
Disclaimer: I am not responsible for any problems from using this guide. Works for G8, G8s, G8x, and v50 Confirmed working on G8 and v50 Requirements: Android 10 QFIL...
forum.xda-developers.com
I flashed the engineer abl_a and abl_b and my first hangup was to enter Fastboot mode I hold Vol+ instead of Vol- as the guide says. But it tooks several reboots and flashing back to the backup abl to figure that out. My device in Fastboot mode isnt recognized by my PC with the fastboot devices command. It is recognized by Device Manager however as Other devices: Android.
Upon boot it gets stuck at VZW splash screen. I can enter EDL mode but when I try to restore my backup abl_a+b it says Data Overflow do you wish to continue. If I select yes it wont flash the backup abl with the size of 32,768 kb. It leaves the abl files at 1,024 kb which was the size of the engineer file.
I can boot to Fastboot but my fastboot devices commands can't see the device. In Device Manager like I said in Fastboot mode it just shows up as Other Devices: Android. On the Verizon spash screen it appears in Device Manager as LGE AndroidNet USB Serial Port (COM3) and in EDL mode it shows up under Ports as: Qualcomm HS-USB QDLoader 9008 (COM11).
I ran the LG Mobile Support Tool and it installed all the proper drivers it says. Maybe I dont have the adb/fastboot drivers? I tried to find them in the SDK but its way more complicated than it used to be. I havent rooted since the LG G2 lol.
Any ideas or help would be so awesome. Its basically bricked cause I cant flash the ABL backups. LGUP program doesn't recognize the device, I did download the correct G820UM20i_00_VZW_US_OP_1124.kdz file so maybe i'll just attempt to restore the stock rom. Can I do that with QFIL??
I cant believe I'm the only person this happened to....
Thanks for any thoughts!!

Boot to EDL mode by holding the vol - and power button while your G8 is plugged in your computer, after you hear a disconnection sound immediately press the vol + until you hear a connection sound from your computer.
Now, open QFIL then look for the abl a and b then flash your backed up abl_a nd abl_b accordingly and reboot. And you're good to go again.
I can help you. Do you fix problem ???

I used the method in that thread to unlock and try to root. When I flashed majisk is when my problem started. I have tried flashing the backup files I made but that doesn't help either

So you are saying you bootloop after you use QFIL to flash Magisk-patched boot_a and boot_b? Do "backup files" mean the original boot_a and boot_b that you flash back using QFIL?
If so, you should double check you are flashing the correct partitions in QFIL because neither of these steps seem like they can result in bootloop. LGUP and start over.

I'm new to the G8 (not LG), so just now browsing these posts.
First and foremost, this thread shouldn't be in this forum. This forum is for roms, kernels, recoveries and other development.
This thread is a question about a guide (which is in guides forum). This 'question' is not development of a rom, kernel or recovery, it's a question.
I'd suggest, if you want people to respond that can help, ask the question in it's individual guide thread, that's where the people that know the most about it will be. If you get no response in that thread, then maybe think about posting the question in the questions forum.
but here? in dev forum? absolutely the wrong place for a question about a guide.
cheers
Thread moved to Q&A section.
Thanks!

So to the original OP; 2 things; If your device isn't recognized when in fastboot mode, that's because you don't have the right driver installed in WinBlows.
You have to download the LG USB drivers, install them, then in device manager select the "! Android" and install the driver (usually says ADB) and then 'fastboot devices' will see the phone.
Second; if you ever get a message telling you that 'Data Overflow' then you are absolutely making a big mistake. When you did the backup of your abl(s) (and other partitions), you should have renamed then one by one, that way you don't make the mistake of naming the laf_a partition as the abl_a partition (or any name other than what ti should be). If you flash the wrong partition you run the risk of overwriting the nearby partition, which would make the device essentially unusable except only to qfil.
Lastly, yer lucky the device is VZW, as they make their kdz available and you can use use lg up to get back to stock. If it was Sprint or At&t you'd be scrambling to find a qfil or bkerler backup someone luckily made that you come across (a much more unlikely scenario).
Good luck, you've probably already moved on from this, but just in case, thought I'd mention the above.
cheers

Unfortunately at&t doesn't make their kdz available. You can be 99.9% positive the only thing this person that wants to charge you 30$ is going to give you is the partitions backed up by qfil or bkerler edl stuff.
With both at&t and sprint, because no kdz, you can only restore (if you didn't back up the files yourself originally), with someone elses backup, and then you have to use qfil or bkerler edl utilities to restore. If you look around in the G8 forums (or the tele group), there's a decent chance someone has already make their backup available.
cheers and good luck.
