[G2 General] wantedtobehaunted:
Hello, new account, but have been following xda for a couple years.

First thank you for your time in working on these methods as they seem to have resolved most people's issues.

So, I am trying to return to a stock ROM after my G2 prompted me to upgrade to the latest firmware, which I assume was Kitkat.

My phone was rooted, and I am now stuck in the TWRP recovery mode. I have attempted your .TOT method as I have a Sprint model, but after following all the instructions (including port 41), nothing happens.

No errors, it just simply does nothing, sits at 0% on my firmware update screen, and no indication of anything back in the Flash Tool's screen.

Just hoping someone can point me in the right direction, thanks.

I finally got my D801 back to stock 4.2.2 from 4.4.2

After hours of beating my head and trying the method listed in this post I went a different route, I wanted to see where the LG Mobile tool was downloading the update file, Well I found it quite easily. If you look in the "C:\ProgramData\LGMOBILEAX' folder you will see a folder named "Phone' This is where the download is kept. So I kept that folder open and I ran the LG Mobile Support Tool by itself. in the beginning the folder will be empty but as it starts to down load you will see the getting larger. So I said OK what if I change the file name from D80110C to D80120A. and replaced it. Well the only problem was that the software started to install before I could make the substitution. So I said how can I stop the install process, Easily, if you pull the cable from the phone before the program actually starts to it thinks there is a problem and pauses the install. BINGO!!! I substituted my file for the one downloaded but I renamed it to so the program would still think it was installing the D80120A update. Now mind you right after the download but before it tries to install (i pulled the cord white it was still at 0%) you need to make the file substitution. The program will ask if you want to retry and you say yes. It will continue the install. After your phone reboots it will be stuck at the T-Mobile animation screen. You have to power down your phone and go into the original recovery mode and do a factory restore. You will see the little green android character and then your phone will reboot to the set up screen and walla you are back to 4.2.2. It took me 5 hours to figure this out but being in the computer field I looked at this from a computer stand point. Now this only worked on my D801. I cannot say if it will work on any other versions. You try this at your own risk as I take no responsibility for anything that may happen to your phone. I am just trying to do my part to help this great community by sharing what I did. I hope this helps my fellow t_mobile users and others if it works. It's 2AM and I have to be up in a few hours for work.

If you have message "no item to upgrade to fix" and if you are root, you can edit build.prop, changing row.lge.sweversion with an older version than the version of the LG server for your imei. LG Mobile Support Tool read this info for watching if an update is available.

I tested it on my d802 and it works geat. I have made tutorial on this method on french web site, and some user used it successfull:

If you notice.... This was all posted BEFORE the offline fix had to be used.... I used to have a different guide posted here til LG changed things with there flashtool which now Has to be offline...
[G2 General] 6ril1:
It seems to me that several times you say that there is no other method to date other than these to be able to downgrade or flashing official firmware, since LG modified its software: It is not correct.

It is also possible to flash the firmware of your choice with the method I described above. This method works very well today and doesn't need to be offline.

We can use LG Mobile Support Tool without being offline for this.
[G2 General] cacciucco:
I think method 1 is almost impossible for newer versions of Windows (7, 8 or 8.1) but method 2 works on any PC and is not really that difficult. The guide is good but implies you have a good knowledge of computing.

In order to replace the files etc. at LGMobileax you need to enable 'show hidden items' in explorer (look under 'view' tab) and then you will be able to see 'Programme Data' under C drive.

The bit that was difficult for me was to add the line to the host file and then save it. I was managing to open the file and add the line but could not save it afterwords because I was denied access. To do this I ended up coping the host file in another location (e.g. desktop) open it, add the line and save it and then all you have to do is to copy and paste (overwriting the original file) to the original location. You will have to give administration permission to do that by clicking the box when it opens.

After doing that follow the rest of the guide, chances are you will not need to install msxml.msi because your computer may be running it already.

Once started it is all very easy and fast.

[G2 General] secret.animal:
Alright, let's see what the issue is. Everything was recognized in lg flash tool. Phone was recognized as port 41. When you put it in download mode. It goes from a screen with it saying download with dots to bigger screen with a status bar.

On the lg flash tool, you have the DLL and the tot file set.

You pressed the yellow arrow.

It checks dll and the tot file.

You had the phone hooked up at that time. Now it sits at the ready screen on the computer.

You disconnected your phone from USB. Then reconnected and it does nothing?

[G2 General] Dodolom:
Hey all-

I've been trying since yesterday with no luck. Followed all the steps but no luck.

The last ROM I flashed before yesterday was the Lightning Rom and I had the lock screen issue, so I wanted to go back to stock and start the whole process again but no luck. When I run the Up TestEX, I do not get the window with Republic of Korea, I instead get this and can't go any further.

After this, I flashed a 4.2.2 based ROM hoping that it would help but that gives me the same result as above.

Anyone has any suggestions?
[G2 General] bobsie41:
If you are running a custom rom, you can unroot/go back to stock by running the software update in the lg PC suite.

Cannot flash recovery?

Thanks for the guide, it saved my ass. But quick question: Why can't I install a custom recovery after I flash back to stock? It worked fine before, but now every attempt to install recovery yields a secure boot error when attempting to enter recovery. Is there a special way to get a custom recovery back after? (And yes, I've made sure I rooted my device too.)
[G2 General] hyelton:
Your Welcome :) I`m really not sure on the recovery part never seen any issue there.
[G2 General] adrig:
I am/was running stock 4.2.2. Currently my phone is bricked, so I cannot use the PC suite. When I use the support tool, it says that I already have the latest version.
[G2 General] hyelton:

Finally back from OTA stock rooted KitKat to Jelly bean, no issues! INSTRUCTIONS

Thanks to sanke and other users here's how I did it: (this instructions are for going from rooted OTA stock KitKat to Jelly Bean factory stock. Model is D802 10a. Before the flash process it was D802 20a which is KitKat version. This process is only for D802 international 32Gb, try on your own risk.) I'm on windows 8.1 64bit and didn't have a problem.

STEPS:

1. Download the KDZ file which is 32Gb open D802 10a (Jelly Bean): Use IDM for faster, stabler download

can't post links guys sorry :( look it up on google or links in the OP

2. Backup!

3. Follow Sanke's step by step tutorial exactly as it is

http://xdaforums.com/showpost.php?p=51034037&postcount=2973.

I should insist on you to not miss any steps, youtube or google anything you can't make on your own. (if you get stuck with B2C installer, google then download "B2CAppSetup.exe" and install again)

4. After all steps of Sanke's tutorial are completed and your phone is succesfully flashed, you should get a bootloop. Don't panic as it's not bricked. Follow this procedure to do a hard reset and get out of the bootloop: ( Taken from Lg support)

Power off the device (long press power button) and ensure it is not connected to any USB cables.

At the same time, press and hold the following keys for 8 seconds:

Power key

Volume down key

When the LG Logo is displayed, release and then immediately re-hold the Power key.

When the 'FACTORY HARD RESET' screen displays, release the keys.

Press the Power key to reset or one of the Volume keys to cancel.

Press the Power key to confirm the reset. The reset will start immediately.

5. ...

6. Profit! I mean, you're done.

Thanks to all the people in xda that helped me recover the phone to Jelly Bean. KK update ruined music and battery life but no more!! Have a nice one :good::good:

On 12B Stock , but still has TWRP Recovery

I followed the KDZ method and my phone is on stock 12B, but it still has the TWRP 2.6.3.3 recovery, which is preventing me from doing the OTA update to KitKat 4.4.2. When I follow the KDZ method everything on my PC appears to work correctly however nothing happens on my phone. It doesn't reboot or anything, it just sits on the home screen and when the PC says success / finished, the phone is still at the home screen. Then I disconnect and reboot and I still have TWRP. How can I get rid of TWRP and go back to stock recovery? Any help is appreciated. Thanks.

I do not know if I am able to reach Fastboot or not. I can get into TWRP Recovery and request Fastboot, as well as hold the Up-Volume buttons on start, but the screen comes on blank after the LG icon goes away.

I can not see the device from my File Explorer in Windows. I have tried to remove each of the 3 devices that appear in my Device Manager and re-install them with the most recent drivers for my phone, which seems to work, but then I still cannot connect to it. The computer recognizes that a device has connected, but I guess I do not know how to transfer files if not through File Explorer or an ADB push.

I have tried to use ADB push but I cannot see any ADB Devices. Within TWRP, I have tried to use ADB Sideload, but the message '//twrp/backups/086c8bd70b935975' not found comes up and so it gets stuck on "starting ADB Sideload feature...."

When I use the "Mount" option in TWRP, Only Data and Cache is selected. I can select System, but I am not able to select USB-OTG

When trying to use the LG Flash Tool (and tried to change every port to 41 for each device I found in Device Manager), it fails with "Model: Unknown"..."device Model is different!"..."Check Phone or DLL!"...."00000000"

I think there were some other things tried too but that is all I can think of at the moment.

which method for a canadian videotron version

Hi, I'm not sure which method I should use to go back to stock firmware

I have a D801 Videotron version. The kdz file is not on the mentioned server but I managed to found the following:

- D801V11B_00.kdz for JB

- D801V20D_00.kdz for KitKat

(would be nice to add theses on the OP)

The D801 videotron is basically a D803 in disguised (according to this)

So just to be sure, is the first method appropriate for my model.

Thanks in advance

Are there any alternatives to go back to official 4.2.2 ?
[G2 General] Chuck_D:
don't click on upgrade start... you have to click on the Normal web upgrade test button

Thanks in advance for any hint....

Try a reset in recovery, PC restart, or another computer. if its getting stuck. There's no tot for the Canadian versions of the phone . flashing a different kdz would not do anymore as all the kdz files are working.
