[Q] lg flash tool wont run

hi iam using lg optimus g pro and trying to flash stock firmware using LG flash tool but i wont flash and prompt low battery but i already charged it whole day..
the cause i wanna flash coz my phone hanged at LG logo boot up due to kernel flash error.. can any1 help me suggest aother tool that can flash
KDZ file into phone...Thank You

Im having exactly the same problem! Tried everything on 2 different computers. They both run Windows 7 x64, maybe that's the problem?
E986 - FreeGee bootloader - CM 10.2 5-11 nightly
I could enter cwm and wipe everything and then i reinstalled cm 10.2 again. Otherwise i would be crying now lol.
But now i still can't go back to stock

I'm also having the same problem, as long as the phone boots into download mode I think there is hope. I have the F240 version and I'm having the same problem as you guys, low battery problem even though the phone is fully charged. Right now I'm trying the "upgrade recovery" thing in the support tool, it is downloading the kdz file again, I hope that during flashing the low battery error won't pop up.
Well I'll post results.

SOLVED!
UPDATE:
Ok guys, I found a solution, I took a huge risk but it worked!
background info:
I have the F240 version, since a lot of apps come on Korean I decided to flash the Panama KDZ file successfully, I had no signal but all I had to no was flash through CWM the original baseband for F240. Since I live in Mexico, I wanted to try the Telcel kdz only to find out I like the Panama kdz better. This were I got into problems, I could not flash my phone anymore due to the "low battery & upgrade unavailable" error. I tried different computers, different files, nothing seem to work. I read that formatting the /data /system /cache partitions would solve the problem... BIG MISTAKE, my phone no longer booted, no recovery, nothing, just download mode. After a few hours a found the solution and so I decided to take the risk.
Solution found here... http://forum.xda-developers.com/showthread.php?p=44372777#post44372777
These were my steps:
- Download Flashtool v1.5.10
- Download DLL file for the F240 (LGUP_GKV)
- Download the TOT File for F240 (this file was impossible to download for me, so I decided to take the risk and downloaded this instead LG Optimus G Pro > ATT Value Pack Firmwar/ BIN_LGE980AT-01-V10k-310-410-JUN-07-2013-0.zip
from the XDA Server found in this thread http://forum.xda-developers.com/showthread.php?t=2438088
- Followed step by step instructions of post 9 here http://forum.xda-developers.com/showthread.php?p=44372777#post44372777
- and here http://forum.gsmhosting.com/vbb/f177/lg-flash-tool-free-no-need-b2b-user-pass-1628819/index2.html
- FINALLY MY F240 BOOTED TO THE ATT ROM.
REMEMBER YOU MUST READ ALL INSTRUCTIONS CAREFULLY, FOLLOW ALL STEPS AND BE WILLING TO TAKE THE RISK!
Hope this helps and it does hit the thanks button!

It's such a shame that the flashing tools for this device suck so horribly. They really are terrible, unstable, difficult to set up. About the worst I've ever used.
I still can't get Flash Tool to run on my device.

The main reason i wanted to go back to stock was because of the annoying delay when i make a call, or receive a call. And sometimes they don't hear me at all... It sucks that a prepaid phone of 15 euro's does the job better then a 500+ phone... In the end... it's a phone right?
I had the problem with stock rom so i flashed to cm 10.2 (i wiped everything before flash) hoping it would be gone but the problem is still there.
Now i found out there is a new .kdz file ( E98610D_00.kdz ) so i wanted to flash that but if i can't get flashtools to work..
* EDIT * i fixed it
What i had to:
Go to flashtools folder
Right-click UpTestEX
Go to compability tab
Select Windows 7
Hit the checkbox for run as administrator
Save
Just to make sure i left the phone on the charger for another hour after it said 100 pct.

Solved
I was experiencing the same problem. Easy way to get it done is
1. Uninstall the current mobile driver from your pc.
2. Download Latest Pc Suite from http://www.lg.com/in/support/pc-suite
3. Install it without inserting the USB.
4. Once installed restart your pc (safe side)
5. Now, remove the battery and insert it again after say 5 seconds and put your phone into download mode.
6. Let the PC and Phone install its drivers and once done open the LG Suite and under 'Mobile Device' tab select 'Restore Upgrade Errors'.
7. It'll download the stock 4.4.2 and you'll be back on track.
Let me know if you are stuck at anything.
Hit the thanks meter if this helped.
Cheers and good luck :good:

[Q] LG Optimus G Soft-Bricked? Please help me to recover my phone

Hey Guys,
First post and i already got a problem because i messed up very much
I used to have Cyanogenmod 11 on my Optimus G, but i got several crashes and i wasnt completely fine with it so i wanted to try something new. So i updated my bootloader from CWM to TWRP and wanted to flash Artmod 5.2 Rom. I was a bit fast with my wiping, so i accidentally wiped the whole phone, so that everything was gone: Cyanogenmod, new Artmod rom i wanted to flash just everything.
I read a bit and thought it shouldnt be a problem then to just sideload the new rom, which i tried to do. I used adb sideload to put Artmod on the phone, everything was fine, flashing went through but i got stuck at the LG boot logo at the start of the phone. I waited like 30 minutes and nothing did change, so i thought something was not right.
I then just wanted to go back to cyanogenmod, tried to flash that through the adb sideload procedure but i got an error which said "error executing updater binary in zip 'tmp/sideload.zip'".
I was kinda thinking something really messed up so i tried to revert the phone to stock rom with the correct KDZ file i searched with the tool linked in the FAQ, everything downloaded but when i tried to flash the KDZ it gave me an error like this:
"12:03:59 Launching SW update
12:03:59 Unpacking KDZ
12:05:10 KDZ file extracted
12:05:11 Extract file error
12:05:13
===FINISH===="
So i searched the forums again and noticed that it should be a problem with the KDZ updater tool because the KDZ file was too big to get flashed properly. I wanted to try the LG Flash Tool 2014 then which is provided here in the forums and should work, it extracted the KDZ file, then opened the LG Mobile Support Tool to flash the file on the phone but there i start to get errors again, it either said that i am already on the correct up to date software version or that i need to disconnect the USB cable, remove the battery, insert it again, restart and try again.
I used several tools for that, i even tried it with an offline method that i found in a german forum, but every method got me the same errors, so i couldn't even go back to stock anymore.
I once tried to flash Cyanogenmod then again when i realized that the error message also told me "This Rom is for a "E975", this is a "GEE"" which i did not completely understand because it should be the total same? I edited the Updater-Script in the Zip file of the rom then and removed the part where it checks for that (1st line actually), then the rom did flash properly, phone started to boot (Cyanogenmod Boot Logo was shown) but when the boot was over i got the message:
"Type Password to Decrypt Storage" with a keyboard to enter the password. (I did never set up any password for that).
Now i am completely confused what i can do the recover my phone, either to stock or just to another rom, every method i tried did not work and i dont have any other ideas.
I can go into Fastboot, Recovery and Downloadmode, but when i tried to wipe again in Recovery it says that it cant mount my data mount point (probably because the storage is encrypted).
Somebody told me to do a hard reset with the keys "Volume down and power" which i tired several times, but everything i get is just the Google boot logo and then happens nothing or i get the Google logo, then the LG logo but after that i get stuck again, I cant seem to go into the "Hard Reset" menu which i should get into with that keys.
Anybody can help me what I could try or got a solution for this? I would be very thankful. I don't wanna loose my phone

Don't worry, that's pretty standard scenario for the first post...

Flash Tool 2014 works great for me every time, so try it again. Make sure you disconnect from the Internet before running it (yank out your LAN cable, or disable your WiFi), so it doesn't attempt to connect to LG servers. And don't forget to put your KDZ file in the same directory with the tool. It should go through just fine. That's by far the easiest method to revert back to stock, to get you to a clean starting point.

Umm... No, they are not the same. E975 is "geehrc", and there is no such OEM ID as "gee". There are many different OG variants. For the cross-reference between the models and OEM IDs, you can look here. Generally, you should stick to the ROMs that are designed for your model, unless you know exactly what you are doing, when trying to flash a ROM from a different platform.

Well i tried Flash Tool 2014 again and seem to get the same error that wants me to disconnects as it stops at the same position like it always did, also doesn't matter if I am connected to the internet or not, everytime it doesn't run through. This time I couldn't even read the stuff that was written in the LG Mobile Support tool because it only shows "????".
Heres a Screenshot:
The settings i made should be the right ones I think, the phone does get recognized by the computer when i plug it in because of the sound that windows makes.
I clearly dont't know what I can try anymore...
And according to the roms: well i only used roms for the E975, which is exactly my phone model, thats why i was wondering about that error message i got
Artmod is for E975, the CM11 was for E975, i even tried Mokee rom but i always got same error messages...

Nobody got another idea? I really am confused because if i can enter downloadmode and recovery there should be a way to get my phone back working.
Anybody knows where i can get maybe some older KDZ Files to go to 4.1.2 Stock rom and try to flash these?

problem

I don't know why you are seeing "???", but here is a couple of things regarding the settings, based on your screenshot:
1. Type should be CDMA (yours is 3GQCT).
2. PhoneMode should be DIAG (yours is CS_EMERGENCY).
3. I would suggest using CSE Flash for a full format (you are using Normal Flash).
Remember, this is a hacked tool, so the settings might not make perfect sense, comparing to the original ones. Just try following the instructions in the OP of the Flash Tool 2014 thread. Like I said, works every time for me...

I don't know why i see "???" also, but it didn't matter
I just tried the settings you told and used CSE Flash which worked out really well.
No i am back to 4.4.2 LG Stock rom. I think the root is gone now, but one thing i wanna ask is if my bootloader is still unlocked and custom recovery is still on it?
Anyway, thank you so so much! I appreciate your help! Thank you!

Glad to hear you are back in business. After flashing KDZ, the root is definitely gone, your BL is locked, and the recovery is stock. You will need to do all the necessary steps again: root, unlock the BL and flash custom recovery.

Need a little help with rooting (download mode stuck)

HI guys, I found the low-effort rooting tutorial written by thecubed but I need a little assistance.
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
I'm at the step where you have to put the phone into download mode and it's now just sitting here doing nothing -- stuck at 0 % for the past 10 min. I'm pretty sure i have the ~4 GB image in the correct location. I took a screenshot here, so you can see. http://i.imgur.com/AiuSX33.png
After scratching my head I realized that I needed to install the LG G4 drivers on my laptop (Verizon version). So I did that, rebooted my laptop and tried it again. NOTTA. Download mode, still stuck at 0% and phone isn't doing anything at all.
Just before I started all this rooting the phone was nagging me about an "update" so of course I took the update *derp*. (bad move)
Before: V98611A. Now it's at 13B
Do I need to find an image for 13B? Is that why the download mode is stuck at zero percent? I'm very new to modding/rooting so I may have completely misunderstood the directions.

Sorry no one has responded to you.
That's never been my experience here at XDA.
I wish I could offer you some assistance, but I have no idea how to help you.
This thread managed to come across my feed on Tapatalk.
Maybe someone will come along that has your device and can help you figure it out.
I just wanted to acknowledge your post.

Buttersman,
Be more specific on where you are in the process, step #, etc.

First, will the phone boot properly if you leave download mode? If so, you may want to follow these directions http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
This will allow you to pull your stock system image, make a backup copy of it on your internal memory, root it, and then place it back on your phone. You could even take on of the pre-rooted system images floating around the forums and push it to you device following the last steps of the tutorial I linked, and skip the necessity of pulling and rooting your own system. With that said, I highly advise you to follow the tutorial step by step and root your own image. That will provide you a backup to flash in case something goes wrong, so you could go back to stock and it will also teach you a good deal about the process.
Finally.. since you are on 13B you are stuck on 13B. Never, never, never try to downgrade to an earlier version (11a, 12b, etc) because it will result in a bricked device. Hope this helps.

Having the same problem
Still trying to figure out the cause of it, but I think it's related to PC driver, as device manager is now showing "device cannot start (Code 10)" in download mode.

If your using Windows you could download USBDeview http://www.nirsoft.net/utils/usb_devices_view.html. This will allow you to see all your drivers and delete all of the installed drivers for you G4. Then reinstall the proper drivers and see if it works. Another option is if you access to a Linux machine since it will natively see the LG G4 without needing to install drivers.

Need help, my G4 is in vegetable state!

First i would like to say hello, second the issue: So i followed this tutorial: how to downgrade my 6.0 to 5.1.1 (official). [Reason is for root] (it was on droidpinoins)
So i checked everything, and it seemed all ok. (all requirements)
Than i downloaded the OPEN European rom (official), and i followed the rest.
LGUP did it's magic (I did install dll first) [spoiler ruined it], after the process it said it's all done.
I see my phone resets and it gets to "LG life is good'' loop (but it's not the same as others loops that you can find in youtube video) [it's the second animation after the first one]. And now is in the vegetable state.
And i have tried to do as suggested in forum, to turn the phone in recovery mode. But it failed, the phone gives me a small vibration and ignores the recovery mode.
So any ideas on how to fix this or wipe the current rom?!
