Fair enough...Just as an attempt to be helpful, and nicer :), in your write up it says "device" I believe in reference to com 41. The phone itself shows up as a device under portable devices...So I changed THAT to port 41...never occurred to me until I read the other guys post "Com" port set to 41 - probably should have though as I remember 2f8 irq 3 etc...Again, just never occurred to me and once done, worked fine.

Also, without that verizon dll (not the megalock one), the entire TOT verizon process will

not

work, so really needs to be added back into the op.

oh one more thing...totally my bad forgetting you do likely get hit with a ton of pm's and post replies from fo'ks that don't entirely read the op...should have put myself in your shoe before replying.

Cheers

No, wait, you're completely missing the verizon dll in your op...without it, the tot process will not work.

The one called: LGVS980_20130902_LGFLASHv151.dll

http://wacomalt.com/dropbox/LGG2/StockRevert/LGVS980_20130902_LGFLASHv151.dll

You elude to it, but do not include a link to it (it's not the link doesn't work, you really don't link to it at all) plus it's also missing entirely from the steps.

I only knew about it from the post of the link above and from wacomalt's post about the verizon process.

Fixed CrossDL D801 to LS980

Better detail on fix.

Check this out.

I decided to reinstall the only firmware I could... this caused random reboots, sometimes 30seconds... sometimes a few minutes.

During a reboot,I put the settings app on my first Jellybean screen (while rebooting, it was easier to get to). Then, go activate Developer mode, then put on USB debugging, and plug phone in... Mine was a little jinky, so I had to take USB out a few times, try to enable... what you are looking for is a prompt that says Allow this computer (type of thing).

Mine had a checkmark box, which said ALWAYS allow. So, that's what i did, and hit ok. After than you should be able to get into recovery.

This is the file I used:

http://xdaforums.com/show....php?t=2545456

and mounted SYSTEM.... now, to install recovery, was a little problematic. I used this one:

http://xdaforums.com/show....php?t=2545456

And, all the recoveries failed, (they have 4 options). Tried all of them, finally phone rebooted into PHILZ.

adb reboot recovery (I used this command, since I thought it was catch recovery better)

In Philz, I had ADB Access, so I just left it there (besides phone doesn't reboot).

in commandline (I am a linux user), I typed:

adb shell

cat /system/build.prop

Which allowed me to see the file

Then, in another commandline window, I typed:

adb push /build.prop /system

Now, your /build,prop might be in a different location, so don't use mine exactly.

Hope that helps!!! When you are done, make sure you tell recovery to boot you into download mode -- this isn't required, but for me it was easier.

There, you should see the LG G2 build type, when you plug in the phone and start LGFLASHTOOLS.

Remember, I used the LGUP_8XXX.dll (the one for trouble)

and, the NEWER TOT, not the one in the package (it's above the package one).

I have D802 international.

For those who have problems with Windows 8, here's how I did it and SUCCESSFULLY DOWNGRADED with method 2. from OP.

I will go step-by-step: (before everything, you'll need to have installed those Drivers from OP..and in your phone go to System Settings - Developer Options - Tick USB Debugging

First 5 steps are simple as sh*t, so just do what it says. If you can't find "ProgramData", go to WinExplorer, View, Options and select "Show hidden files, folders, etc." Now continue with those steps until you reach Method 1. Then jump to Method 2, because I'm explaining that method..because it worked..

"1. Go to windows/system32/drivers/etc/ and open your hosts file! (open it with wordpad)"

- If you have Windows Defender, open it, go to Settings - Excluded files and locations, type C:\Windows\System32\Drivers\etc\hosts and click ADD.

- Go into METRO, find NOTEPAD and RIGHT CLICK - Run as administrator - Press Yes

- File - Open and navigate to C:\Windows\System32\Drivers\etc\ and double click on hosts

"2 . Add this line at the end of the document: 127.0.0.1 csmg.lgmobile.com"

- Go to the end of the page and just add 127.0.0.1 csmg.lgmobile.com

"3. Save hosts file"

- File - Save

- Close Notepad

"4. Install msxml (you can find it in the downloaded KDZ_FW_UPD_EN folder)"

- Right click on msxml file and Run as administrator. Press Yes.

"5. Start http in the shttps folder"

- You have folder SHTTPS, open it and right click on http - Run as administrator - Press Yes (leave that window opened, just minimize it if it bothers you).

"6. Start Windows Enabler and turn it on (system tray!)"

- In folder KDZ_FW_UPD_EN, you will find Windows Enabler application. Right click on it and Run as administrator - Press Yes.

- You will find icon in your taskbar (with couple of blue windows one behind another), just click (left click) on it and it will say ON.

"7. Start UpTestEX_mod2_marwin"

- In same folder (KDZ_FW_UPD_EN), you will find application named: UpTestEX_mod2_marwin, so right click on it, Run as administrator - Press Yes.

"8. Flash your .kdz as you normally would"

- It means you have to set

PHONE MODE - EMERGENCY

SELECT TYPE - 3GQCT

SELECT KDZ FILE - Navigate to downloaded KDZ from OP step 1.2)...and double click it

Click on NORMAL WEB UPGRADE TEST

Click on UPGRADE START

Window will show, and you click:

CLEAR PHONE SOFTWARE UPDATE REGISTRY

Country: Different Country

Language: (here it didn't show anything, but it's OK)

PRESS: OK

Sit and wait.

If your phone didn't go to Download Mode, don't worry, just put it by yourself. Google it how.

When everything is done, you might be in bootloop. Worry not, you didn't do factory reset, which you can do by some key combo. Google it.

I hope this helps, and now I have to go because Champions League is near and I want to see Bayern Munchen OUT tonight. I don't like them!

As of right now phone gets stuck at LG logo but i can get into twrp.

when i connect my phone into the pc it is fine, but if i go into download mode, my pc stops recognizing the device, which is stopping me from downgrading. is there anything i can do so my computer will recognize the device IN download mode? ive tried all the methods to downgrade and it wont work and i believe that is the reason. i just got this phone and i really want to downgrade it so i can root it.

i have a tmobile g2
[G2 General] hyelton:
When you say your computer stops recognizing the phone when its in download mode? How do you know its not? Are you checking in Device Manager?

[G2 General] waz675:
I think that's the problem I had start of the year when trying to flash a kdz to go to stock. Stopped at 49% with that or a similar error. Litey tried 12 plus different ways and kdz files over a week. Using a tot and DLL (extracted from a kdz I think or somewhere else, forget now, chronic pain kills my short term memory) method that used a different software to install made it work / flash first attempt.

Its in my history somewhere, late January or February if you really want to look, Google "tot DLL waz675 xda" probably will quickly find it.
[G2 General] haoleflip:
Don't worry, I just fixed mine a little bit ago!

Here's exactly what I did.

1. Download the firmware for your device here (In my case it was the file named "LS980ZV8_13.zip" because I am on Sprint. You should also download the .dll file that is in the same folder for your device.

2. Download LG Flash Tool here

3. Download drivers if you don't have them.

4. Download this Megalock DLL

4. Follow the exact instructions for "RETURN TO STOCK TOT METHOD" on the first page of this thread that is found underneath method 1 and method 2 that are in the gray box. That was the easiest method for me to understand.

Hints: To change the port to COM 41 go to Control Panel>System and Security>Device Manager then click the Ports tab and you should see the LG serial port. Right Click on that and click Properties>Port Settings>Advanced and then change the COM Port Number to COM41 and click OK.

Hope this helps!

EDIT Sorry! I thought you needed help with the whole thing. If you are stuck in the same spot, unplug your device then plug it back in after it says "READY" in yellow. This will prompt the download.

Hi guys :)

Could someone help me? I'd like to go back to a stock 4.4.2 ROM.

However, when I tried to flash a stock 4.4.2 ROM originally I had the "touchscreen issues" you see reported all over the place on the web, where the calibration was off and you can barely touch anything on the screen etc.

My phone is a 16gb D802 from South Africa, can anyone tell me which of the 4.4.2 original ROMs would be "safe" for my device?

Thanks!
[G2 General] HighlanderZA:
Hiya bud - you don't say what you are on now?

I was on stock 10B - came standard on D802 from Vodacom.

I rooted - but did not flash a custom recovery - this actually prevented any OTA from installing successfully - always *****ed about the phone being rooted. So decided I might as well go the whole hog and flash a custom REC and a ROM.

I used the Offline Procedure - (http://xdaforums.com/showthread.php?t=2625044) - to flash the Netherlands stock 10F KDZ and after having LTE issues with that, decided to flash CWM and try the Pardus ROM - this all works great and is very stock. No issues so far!

So, as far as I know, stock here started with a 10B version and the OTA's tried to update me to 10D. I haven't seen any ROMs or KDZ files specifically available for us here though!
[G2 General] margaretiak:
Third "tot" method worked like a charm on internation d802.

In the last step there is no need to reboot, just unplug phone and plug in again. Proces will start.
[G2 General] hyelton:
Did you ever perform a factory reset after flashing? When flashing things will force close and not work correctly if you don't perform a factory reset..
[G2 General] em2drvr03:
I have done everything possible that I can think of. I have noticed that I need debugging on but my device won't let me get to those settings. I thought a factory reset would have worked but once I did one I kept getting the same force closes one after the other. I'm just worried that when I send the device back to T-Mobile they will find out it was rooted.
[G2 General] kudathove:
Hi, which TOT file did you flash? Im on the 16Gb D802 and I can only see the French version, will that flash to the Uk D802 without any problems?

For the UK you have to use the kdz method.
[G2 General] Amel.Spahic:
Install LG drivers.

Connect your phone in download mode with PC, go to device manager, right click on that yellow triangle and "Update driver software". Browse to LG drivers path (probably in C:\Program Files\LG something) and it should install it.

[G2 General] sagemda:

[G2 General] geoff5093:
Update.

I gave up trying to use the first method, so I tried using the TOT method and that worked. I'm on 10B now and I'm going to try and take the 12B OTA, then upgrade again to 4.4.2.

The only thing I can think of is I had to change the port to COM41 for the TOT to work, but I don't know if that would make a difference in the first method.
[G2 General] hyelton:
Its stated in the OP to change to COM41 for the TOT method you have to. It's not needed I don't think for the kdz method.
[G2 General] geoff5093:
Yes I know, I saw that and did it. I was referring to the first method, I have no idea why that method didn't work. (Error posted a few posts above)

[G2 General] krononaut:
First off, GREAT WORK! I like the new instructions for AT&T. Ran a few things that I found fixes for in the comments that may be worth adding to the OP.

I flashed my AT&T phone from KitKat rooted back to 4.2.2 stock using your new instructions. I went to 4.2.2 because I already had that tot file downloaded from a previous reflash. The kitkat tot file on your site was indicating it would take 3 hours to download at the time, so I went with what I had on hand.

Here are the hiccups I encountered:

I followed the instructions, and after you click on the Yellow arrow, it just sat there at the READY prompt. I reinstalled the drivers and rebooted about 3-4 times before I came to the comments and found haoleflip's comment to unplug and replug the phone.

After I clicked the Yellow arrow (step 13), unplugged and pluged my phone, the entire flash happened and after the last reboot it came back up with a solid red led and nothing on the screen. The flashtool status stated that everything passed. I went on to step 14 to leave it plugged in and put it back into download mode. When I did this, the flashtool started the process all over again. After the second time it came up as passed with a blank screen and solid red LED, I unplugged the phone and held the power until it rebooted. It came up just fine. May want to adjust these so people don't flash their phone twice.

After going from KitKat to 4.2.2, my phone kept coming up saying "no SIM card installed". I wondered if it was because I wasn't on KitKat anymore, so I downloaded all the updates and still nothing. I tried a couple of factory resets and reboots per some of our previous comments with no luck. What did seem to work though was unplugging the phone from the USB, and powering it off (not reboot). After this, the phone came up just fine.

Thanks to everyone who helped make this an easier process.
