Hey Guys,

I sent my Optimus G pro for a J-TAG repair but when I turned on the phone it got no signal or very weak signal. I opened the phone and noticed that the antenna cable was cut. I bought a new cable for it installed it and the phone still reads no signal or very low signal.

What could be the problem?

Windows 8.1 issues

Hello all,

I've been pulling my hair for a long time to get a good USB configuration for Win8.1 and LGFlash.

Device cannot start (0x10), Unable to apply correct driver and port to the COM device. etc.. etc...

What made it work it to simply remove the USB3 microsoft driver by simply disable it in the BIOS. Then the whole flashing process went very smooth.

So basically Microsoft has some serious debugging to do with their USB3 drivers.

AT&T soft bricked my phone

First off, I want to say thank you for giving us a way of ...lol..."bootloop escape" on our LG OG PROs. :D

Second, I've recently purchased a well used, but rooted and bootloader unlocked LG OG PRO from an eBay seller. Everything was going swimmingly until the corporate whores of AT&T forced themselves upon my precious device in the form of a KitKat update, which ultimately soft-bricked my device. :mad:

My question to you is this: will restoring my device back to stock re-lock the bootloader as well? I know this is an old post and you are a busy man, but, if you could let me know something at your earliest convenience, that would be great! I await your response; thank you in advance.:cool:
[LG Optimus G Pro] spawn4son:
Yes It will lock the Bootloader, it will return the phone to its original state.

UPDATE: around 3a.m., I've updated the LG mobile drivers and tried the process again. I no longer get the F0000002 error, but now it's not moving anywhere past "READY" in COMPORT41. It's progress, but still searching for the latest LG flash tools.:silly:

[LG Optimus G Pro] mburt27:
After the status is "Ready" in port 41, you need to (DONT close LGFlash Tool) (1)unplug the usb from the phone, (2)power off phone and put in Download mode again. LGFlash Tool will immediately start the process.

[LG Optimus G Pro] mbm29414:
(I hope this isn't a duplicate post.)

I have been trying to un-brick my E980 for some time now (off and on). I re-started with my latest attempt last night. So far, I have done the following:

1. Downloaded all the files I need (.dll, .tot, LGFlashTool, etc.)

2. Installed the LG drivers on my Windows 7 VM (running in Parallels).

3. "Installed" the phone on the Windows 7 VM, setting the COM port to 41 in Control Panel.

4. Turned off internet and reset time to February 2012.

5. Run LG Flash Tool, using a registration key I found.

6. Pointed LG Flash Tool to the .dll and .tot files.

7. Clicked the yellow arrow.

At this point, the COM 41 box says "READY!!". After this point, when I turn my phone on into Download Mode, nothing happens. I have tried this maybe a dozen times, using slightly different techniques each time. Nothing seems to get LG Flash Tools to see that the phone is then connected and ready to flash. Control Panel *does* report the phone attached. I'm using a Logitech USB cord that successfully works with Android Studio for deploying apps to my other phone (LG G3).

For what it's worth, under Control Panel, the phone shows up as "LGD AndroidNet USB Serial Port (COM41)".

I have also tried doing both "UPGRADE DL" and "BOARD DL", but neither seems to change anything. I've also tried using the .dll and .tot files both from my Mac side ("\\psf\Downloads\...") and copying them to the local C drive. Does anybody have any idea on how to actually trigger the update process?

[LG Optimus G Pro] madmack:
I think you might not be following each step. Did you click on the yellow arrow before plugging the phone back in while in download mode for example?

Maybe start from scratch if this error still comes up. This method worked for most of us here so you most likely have some sort of user error. As long as you didn't touch the bootloader partitions (I doubt you did by flashing the things we have here in xda), then this method should bring your phone back to life.
[LG Optimus G Pro] Carlosfulll7:
The phone is not plugged in prior to clicking the arrow, what i do is.

Load the files, click ok-- then the arrow as i was told in the instructions.

What concerns me is the fact that i never get a "finished/ready" pop up upon hitting the arrow, it just shows a small centered "waiting" box, that's when i connect the phone and gt it to dl mode.

I have also tried having the phone in dl mode then connecting it after hitting the arrow but haven't gotten results.

I did configure the port to com41 and i am using the original usb cable so there is no connection issue.

Do you have DLL and TOT files for F240x ?

Mine is F240L, got stuck in U+ LTE.

I was trying to flash it using LG Flashtool 1.5 according to above thread.

The problem is I don't have the correct DLL and TOT files for my F240L, the thread above only goes for E988.

Anyone could help me ?

Thanks in advance.
[LG Optimus G Pro] chimmot307:
Mine is F240L (korean version). Got stuck in U+ LTE logo. Only DOWNLOAD MODE available.

When I try to flash using KDZ Updater and LG Mobile Support Tool, all seems not working (still stuck in U+ LTE logo).

The only one work is 10T.kdz from Baidu.com. When I extracted it, will become .CAB file. And extract the CAB got 2 file :

- LGUP_GKV.dll

- F240L10t_00.dz

So I used those 2 file in LG Flashtool ( I don't know if those the correct files to use in LG Flashtool, cause I can't seem to find DLL file for F240L, but I think for S/W file is correct ).

Used port COM41 to flash (DOWNLOAD MODE is activated on F240L). Then I unplugged the USB cable for 5s, and replugged it. Error message appears as follow.

Am I using the correct DLL file to flash ? If not, would you be so kind anyone to upload the DLL and TOT files so I can flash my F240L ?

You saved my life.... Thank you!

I rooted my phone two days ago and then got the LG update (from July) and accepted it instead of declined it and I soft-bricked my phone last night just before bed and wasn't sure I'd get a chance to do this for a day or two, but did all the downloads last night and woke up a little early for work this am and got it back up and going!

Thanks for the easy instructions!! :good:

FYI: Anyone wondering how long it takes, it took about 10-15 minutes from the time I clicked the yellow arrow to start the process until it finished. Probably another 10-15 to read the instructions, install the drivers/software and get everything else prepared. Total time of 20-30 min, excluding the download time.

I noticed this guide looks to be ONLY for the LG E980. Here is how to Recovery International (not USA) Devices. It should also work on the E980 with no issue as well.

How to flash ROM:

1) Download the Rom You need for your phone. They are at the link below!

http://storagecow.eu/index.php?dir=Xda/LG+Optimus+G+Pro/Stock/

2) Download LG mobile support tool and Install it. (It will open up when its done just CLOSE IT OFF)

http://csmg.lgmobile.com:9002/client...2CAppSetup.exe

3) Download / Install FlashTool (R&D Test Tool)

http://storagecow.eu/index.php?dir=X.../Programs/

4) Install LG drivers (can skip if you already installed)

http://storagecow.eu/index.php?dir=X.../Programs/

5) Power off your G pro, press Volume Up + Volume Dn keys and then plus-in the usb cable (enter to a download mode)

6) Extract FlashTool and run UpTestEX.exe

7) In R&D Test Tool window,

Select Type = 3GQCT (top left hand side)

PhoneMode = DIAG (top right hand side)

Select kdz file = click to select your LG stock rom *.kdz

Click "Normal web upgrade test" (bottom right hand side)

Then another window "read phone information" pop up, click "Upgrade Start" button

wait a few seconds, another window "Select Country & Language" pop up,

=> Country=Republic of Korea

=> Language=English

you can click ok to proceed

8) All Done and wait for finish!

9) Be Sure that after flashing to perform a reset as for some reason flashing this does not remove what was there before until you reset.

I`m not sure if I should Make a Thread or not, I think we should add this to the 1st post.

I think Windows 8 has issues involving connecting the device to the computer. So I am now using a computer with windows xp and it is working properly.
