LG G2 Stock Firmware (Go Back to Stock)
- Thread starter hyelton

Worked perfect for me once I realised programdata was a hidden folder! Make sure correct drivers are installed I had to boot into download mode then connect to pc to do this but method 1 worked a treat for me. Thank you!

Currently uploading some more new Kdz`s
Some 32gb kdz's? I'm like waiting a few weeks now for a nice one
After it gets to the "downloading file to upgrade" in the LG mobile support tool, it cuts it. Can anyone help me please? I really need my phone right now..
I'm having issues with loading the stock 4.2 firmware for my Canadian Telus D803 with the first and second method. I kept getting VB script errors so I switched to the second method of editing the hosts file. This seemed to work however my load keeps failing at 49% at the download screen using the 4.2 image. If I try to use the Telus 4.4 it can't even find the device. :-\
I've gone in and uninstalled all the LG drivers, software, and manually deleted the lg folders under program data and reinstalled exactly as per the guide.
Any ideas? I was able to do this before prior to the download fix being required.

So exactly what did you wipe in TWRP? Also, did this method bring everything back to stock including the stock recovery and getting rid of the "rooted" flag in download mode?

I have these symptoms too, and I also have these (secure booting error, blank screen, no download mode):
Honestly I've poured over 12 hours into fixing my phone in the last two days trying this method, the Verizon-specific .tot method, etc... small successes followed by terrible losses. I am just going to go beg Verizon like an idiot even with a phone that says ROOTED because at this point the amount of stress I've been having is killing me
T-Mobile wasn't able to do anything free for me. LG however can repair it for you, I'm not sure how much it will cost you though, you have to mail it in and then they give you an estimate. If they refuse to because of root just leave a ton of negative reviews until they do something about it, and continue trying LG Flash Tool. They need a driverless mac variant of this as well as a more Windows 8+ compatible version.

Some people tried using recovery mode for other things or didn't have one when their phone got screwed up. All I get is a stupid error. So we have to use Download Mode since it's the easiest way for the computer to pick it up. I've been unable to fix mine though, it stops about 10-15 seconds through and says the phone disconnected, but I do also have Windows 8.1 :/.

Is it possible if i flash a ZV8 radio then do OP?? I dont need spark nway.
HI,
When I try to run B2CAppSetup i get the following message:
'To check for software upgrades you need to connect your PC to the internet and press continue'
But I am already connected to the internet???
What to do?
I get this as well but couldn't find any solutions in the thread.
Anyone got any ideas? thx
You need to follow the (manual) guide. I just tried it yesterday and it worked fine.
If you try to use B2CAppSetup from LG you will get this "connect to the internet" error because of the entry in the hosts file (see guide).

Open 32GB LG G2 (D802) here. Download mode (holding volume up while plugging in USB cable) shows "rooted" but I have not rooted it. Can others confirm this?

See the first post in this thread.
First, follow steps 1, 2, 3, 4, 5.
Then follow "Method 2. edit host file" (8 steps).
I edited the hosts file this way in Windows 7:
1) open start menu
2) enter: notepad c:\windows\system32\drivers\etc\hosts
3) press ctrl+shift + return (executes the command with administrative rights, needed because hosts is a system file)

1.Network connection error is NORMAL, move the window over and you'll see its actually most likely flashing
2.If your getting errors when doing the kdz method and running a custom rom that could be the problem and you'll need to use the TOT method.
3. Getting connection errors? Check under device manager to make sure you see LG something related under communication ports (Windows 8/10 ports might be hidden)
Make sure your using a USB 2.0 port!! USB 3.0 will NOT work.

Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.
CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.
No need to choose desired language, it automatically change to English as a default setting.
Wait until 100% to complete !
REMEMBER if you get Bootlooping after flashing perform a factory hard reset!

5.Copy MegaLock.dll file to C:\LG\LGFlashtool (This might be a hidden folder so enable "hidden folders". Replace the old MegaLock.dll file)

Thanks to @shakeyabooti for LGUP!
Download LGUP from HERE
Install the file with the DLL name in them first and then LGUP_Install_Ver_1_14_3 Then copy the folder "common" to C:\Program Files (x86)\LG Electronics\LGUP\model (this should resolve unknown error)
Make sure you have downloaded the required KDZ file MM or LP
Open LGUP on your computer "make sure your phone is plugged in"
ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONNECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it.
LG Drivers: in First post
TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
IMPORTANT!!!!!!! shut down LGUP!
Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient
TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a FULL wipe, tick BIN file. Press Start. Make cup of tea and be patient
