[G2 General] tarnagy:
Unfortunately I was in trouble - from my own mistake.

I wanted to install the Android 8.1 custom system with TWRP on my LG G2 (D (802 int.) Phone and I did a complete wipe before it.) The system did not want to install due to a bug (TWRP was old?) And then I - I'm an idiot - I turned off the appliance.

He's dead now, he has no downlooad, no recovery, he has nothing.

I installed Ubuntu (18.10) on a partition on my laptop, but when I type "gdisk", it says the program is not found ... If I turn it on, only the LG logo looks like nothing goes on.

Can anyone help me?

Update:

You can enable Download mode. I do not know how, but I tried many times, and once did it.

[G2 General] juicer52:
Old LG Optimus Exceed2 VS450PP resurrected from desk drawer. Battery was dead and once charged on another exact same phone, I got the warning about boot verification error then screen goes blank and only back light is visible.

Was able INITIALLY to get to a screen that offered 4 options continue boot, factory reset, wipe cash, safe mode. Selecting factory data reset gave me a spinning arrow for a few seconds then went to blank screen as above. Choosing any other of the four goes to blank screen. Not able to enter download mode regardless of any variation of button presses.

Followed your directions but still no download or recovery mode.

This is where I go down the wrong path.

Though using your method, I now had lights on at the home button (none before) I still got the same boot error message but nothing else. So I thought I'd retrace my steps BUT this time failed to use the correct numbers I got from the gdisk command and now I have really farked it. Linux (Mint 18 or Knoppix) sees the unit as USB HDD1 USB QualcommMMC Storage. So I can't even get back to where I was before. No home light and now the LG logo flashes for a second and screen goes blank with the exception of the back light.

ls /dev/sd* reports numerous drives a to h. Only sdb (where the Knoppix usb live) shows any results from gdisk -l /dev/sdb. Changing the last letter to correspond to the other responses gets me a specified file does not exist / problem opening...

In Windows (7 or 10) Device Manager the unit is listed under Portable Device as E:\ and under Ports as LGE AndroidNet USB Serial Port Com5.

This phone is a useless 3G that I am just trying to learn on.

Have I totally screwed the pooch?

I read somewhere about shorting the test point but haven't seen a description of where that is on my particular board. Not clear either (battery out but usb cord still connected to PC?)

Any suggestions appreciated.

Is all hope lost?

[G2 General] giptorres:
Hi I have an d802 with this error

Can go to download mode but couldn't go back to stock through the popular tutorial here in XDA

The latest rom installed was the lineage OS 16 and doing the latest update got into a bootloop to TWRP and trying to fix that I got my phone in to this mess

Now I need to know how could I get these .img files for my ROM and get my phone back working

Also I would like to know if I really need all the files bc i'm pretty sure the problem with my phone is the TWRP bc I tried to reinstall but by a mistake I downgraded it(but it was the recommended version on the TWRP site) and that was when I rebooted and got this problem. If I only do the TWRP img could I just use the one I had working last time? I only have it's zip is there a way to get the .img file somehow? Sorry i'm a bit newbie to this and whish to fix this with as much detail I can gather beforehand.

I've already made an post in the ROM thread here in XDA imploring for someone to send the files but it's been 3 days and nothing

I really need to get my phone back, plz help

The Problem:

I already installed this ROM (https://xdaforums.com/lg-g2/orig-development/rom-lineageos-17-0-unofficial-d800-d801-t3967345) and Worked all fine, but when I'm trying to install some Magisk Modules and rebooted my device it get stuck at LG logo... I can access Download mode but not my TWRp recovery.

Any solution to my problem? Just a little help...

Thank you so much anyway!

The Solution:

Thanks to all that tried to help me! I appreciate it a lot! Thank you so much!

My only solution was to try short the capacitors following this thread:

https://xdaforums.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404

Thanks God I don't need to mess with the board!

My problem was that I tried this ROM LineageOS 17.1 with latest version of TWRP Blastgator. Everything was running fine until I flashed Magisk and installed some Mods, then the device rebooted and I get stuck at logo!

No System and no Recovery access, only Download mode! :crying:

Then I followed this thread:

https://xdaforums.com/showthread.php?t=2432476

I used to install some custom ROMs like Cloudy G2, LineageOS, Resurretion Remix and AOSPX Pie and tried to this new one. I never had any problems!

This time I realized that my device was forever bricked, my last hope was to short the capacitors but I tried all ways to back to Stock because in Downlaod Mode my device was recognized by Windows.

I tried this in Windows 10 x64 but no success, then I formatted an old HD with Windows 7 x64 to try again!

Old Flash Tool get me stuck at 2% or 4%... no success in both system with all LG drivers available... NO SUCCESS!

https://xdaforums.com/showpost.php?p=53313255&postcount=5400

LGUp only gives Unknow Device and never start but it's seens the device on port 41 - that I changed following the tutorial.

My last hope was New Flash Tool but I needed TOT file for my Device - D805 not D802 and the correct DLL. initially I didn't find anywhere... Like this guy:

https://xdaforums.com/showthread.php?t=2583851

I give a lot of tries... a lot of different files, DLLs, tried .KDZ and .DZ, only errors and errors... a lot of "Failed to Load()"...

I'm getting frustrated until I see this thread:

https://xdaforums.com/showthread.php?t=2582142

And found this mine of gold of Downloads:

http://downloads.codefi.re/autoprime/LG/LG_G2/

And again, thanks to all, there is a hope in the D805 folder!

I get the TOT File: BIN_LGD805AT-00-V10a-724-05-AUG-23-2013-16G.zip and tried the LG Firmware Extractor (https://xdaforums.com/showthread.php?t=2600575) to get a new DLL (LGUP8974.dll).

And voilà, like a charm that WORKED!!!!!!!!! :fingers-crossed::highfive::o

It installed Jelly Bean the with the Official LG Updater I installed Kitkat and finally Lollipop.

Later I'll try this LineageOS Rom again! ;)

I hope I can help someone in need like me!!

I thank this forum a lot!! :D

And please excuse my English! :p

Thank you so much!
[G2 General] antryout:
I have LS980. I flashed LS980ZVC_12.tot via flash tool, then rooted the device, and incorrectly installed autorec for d800. This resulted in "fastboot mode started." I could not enter download mode. I flashed laf.img for ls-980, that was not enough to reach download mode. I reflashed laf.img, boot.img and recovery.img (not twrp/ the stock one.)

Now the device only shows LG logo. If I try download mode, it shows download mode on screen, but it doesn't proceed to firmware update page. So device isn't recognized by laptop. No Com ports. If I try factory reset, it displays "Factory reset processing" only, but it is stuck there. Not moving forward.

How can I put the device in fastboot mode again?

I tried holding VolumeDown and connecting usb cable, stuck at LG logo.

[G2 General] Triad79:
Yes I have, they're not digitaly signed but I installed it anyway.

When Linux VM is running windows doesn't recognize anything, Linux as I see doesn't recognize too, that picture says that linux sees only its main partition, linux filesystem and swap. There's no USB bulk device of any sort.

The fact that windows doesn't recognize device when VM is running is enough to say that Linux does take some role in trying to recognize device but fails, because as soon as i disconnect Virtual machine, windows takes over and detect it as a Qualcomm HS-USB Diagnostics 9006...

Do I have to change some linux settings... Ordinary USB device isn't recognized in Linux too, I read that it needs to be set up, third time linux user after many years, so I didn't know that Linux still needs so much hand job after all this time since knopix and so on!??
[G2 General] Partager.info:
I've used ubuntu to solve my problem. I have not experienced your problem.

When you plug your phone to windows, do you have prompt windows asking for formating partitions?

If it is the case then just VM, unplug your phone and plug it again in VM and keep trying the procedure.

Good luck.

Holding Power+Vol down or Power+Vol up shows the boot certification verify error and after a few seconds it turns off.

Thanks for this method, I'm guessing when I messed up my G2 it wasn't as bricked since I could get into download mode. After several hours and having to do several tricks and such from posts all over the net I was able to get back to stock using LG FlashTool. I've been flashing my phones for years and I really thought it was dead and FlashTool was doing nothing for me nor LG Mobil Support Tool or TWRP using sideloading or trying to flash other roms, in the end FlashTool got me back to stock no root out of the box but man if not for the instructions from others smarter than me would never have gotten it back. Thanks to you and all people that take the time to write up guides, especially ones as thorough and concise as this one.

Ask for help

Hi Partager, I read this method and tried it. However there is something different, could you give me some advice?

In the step: "ls /dev/sd*", my result is that

"sda,sda1,sda2,sda5".

And my friend told me that this is the partition of linux not my sd card, that means Ubuntu did not recognize my G2's sd card.

(PS: I am sure that I disconnect G2' usb and connect to virtual machine->Ubuntu, I can found its usb icon in virtual machine.)

My G2 has almost same situation as you desciption. I can not write the correct laf.img to G2, and that's the root reason of my phone.

Just search on google how to install linux on virtual machine or make a bootable usb stick with ubuntu inside. then you can use the tutorial.

You need abslutely dd commands to push required files into your G2 partitions. dd commands don't exist on windows.

You should download the appropriate img files to verizon. I've made the tutorial for D802. I hope you did not download the same files.

Just do it again. Download files from here: http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware

Just chose the right version from 11A and 10B, enter the folder and download the required files in the tutorial. push them and restart your phone it should reboot into twrp recovery.

Try to install ubuntu under virtual machine. use Vmware client to install it. Install qualcomm qhsusb_dload drivers on windows then start vmware, plug your phone once ubuntu starts, it should be detected as Qualcomm HS-USB... in ubuntu. and start following the tutorial.

You can stop the "unable to mount..." error messages from popping up by disabling

the automount feature of Ubuntu.

Look, depending the situation you are living here, it seems you can go into download mode.

Just plug your phone to PC then keep holding volum up and power boutton until it restarts, then release them and hold them again. Your phone must enter download mode. At this stage you can flash stock rom using lg flash tool. Then just follow this tutorial:

I have the files for my ls980 and Ubuntu 12.04. Every time I connect to the usb the backlight blinks every few seconds and repeatedly disconnects. After a few cycles of this Ubunt.iu freaks out and crashes. When I am able to get it stable enough to use terminal and dd the files the phone starts the blinking backlight again and the whole problem starts over again. I can't use the r&d tool to recover using the .tot because it recognizes it as the d801 and ls980 (I had the tmobile from on so it was unlocked) any way to fix either problem?

This doesnt happen on Windows. Is there a way to use Cygwin or should I use a different Linux or should I use VMware?
