I'm currently stuck at step 5 of method 1. I'm not getting the window to select country/language. I started over and realized that for some reason the "phone" file isn't extracting from LGMOBILEAX. It only extracts the other files (b2c client, language, uptest, lgmlauncher). Anyone know as to why this is happening?

The T-Mobile tot file doesn't work! It's corrupted, says the file is invalid after downloading it 2x on my computer.

So 2 months ago, I installed the g pro 2 rom on my T-Mobile 801 lol. I know im a moron. I thought it would work since there was a flashable zip for the 801 version, but hey the flash failed and it rebooted lol , but the rom does BOOT and all that junk. I can also get into download mode.

So in my settings it says, i have no imei, model # is unknown, no baseband version. Build number says OptimusRs-G Pro2 ROm V2.

Software version V10d-VDF-COM

i also have the tmobile 801 tot file, but the file is invalid. Tried the kdz and such, errors up because im on 802 firmware from the g pro 2 rom install.

Been lurking the forums for a while trying to get it fixed with no avail. So if anyone with knowledge about this, help me! lol

Been using my nexus 5 for 2-3 months now, it's not the same as the lg g2!
[G2 General] hyelton:
So your following the guide to go back to stock 100% ?? These files are not flashable. Read the entire guide and use the tot method. This method has worked for everyone that's used it on T-Mobile. Files are NOT corrupt.

4. go to C:\ProgramData\LGMOBILEAX

remove all files and folder

5. copy all files and folders from LGMOBILEAX that you unzip from step2 to C:\ProgramData\LGMOBILEAX

WTF? This makes no sense to me. So I downloaded the files, unzipped them to my download folder and then moved them to my desktop. I ran the file from withing the KDZ FW folder .. Then closed the program (it stopped responding after I closed it.... then I'm supposed to go into c:\programdata. i dont even have that folder..... in program files there isn't LGmobleAX either... only place those files are, are the desktop... so okay. if I assume that's the same thing.... I do a search on my windows 7 CPU and find lgmobileax, which is the same folder on my desktop... then i'm supposed to delete everything, but then i'm supposed to copy the same exact files i deleted into the same folder i just deleted everything from in my desktop..?? Doesn't make sense. I'm sure I'm reading it wrong, or somethings out of place.. I'm downloading the tot. files as we speak, but would rather do the KDZ method from the sound of it..
[G2 General] jesssiii:
Try booting into twrp and wiping system under advanced wipe. Then turn phone off and do the volume up/plug in computer for download mode and try the tot again.

turns out I'm an idiot, was trying to change com port under modems for phone rather than Ports(com and lpt). as soon as I did it under ports it worked. lesson learned.
[G2 General] linhvng.2212:
Thanks!

Thank you for your guide! Work very well!

just FYI, you can go to download mode by holding Vol UP button and plug the USB cable into the phone :)
[G2 General] lampardd:
Thanks for this useful post, you saved me once but I'm having a problem this time.. I cannot boot into download mode using volume up+volume down combination. However I was able to get into download mode by just using the volume up button but now it immediately goes to Firmware Update screen and stuck at 0% after download mode so I can't flash because lg suite says phone is not plugged in at around 10s%. Any help would be appreciated..

How can I have stock recovery? I forgot to back it up.

Thank you.
[G2 General] minur:
thank you!
[G2 General] Jorq1H:
First of all, OP, thanks a lot for this! It saved my ass last sunday.

After rooting the phone, I accidentally restored some system-apps from my N4 titaniumbackups, which resulted in a lot of FC loops. So I went into recovery (TWRP, which I've never used before. CWM I know very well). But stressed out as can be, not knowing what to format, I accidentally formatted the storage (huge noob-mistake) and I ended up without OS, just the recovery. And as I can see from my google searches, a lot of people have done this exact thing.

But low and behold, here's a thread that contains stock roms and a way to flash it. I follow the instructions to the point and ended up with a newly installed, unrooted phone (still shows the root-flag, though, someone really needs to find a way to remove that). So I rooted once more and did a thourogh titaniumbackup restore without any mistakes and here I am, a week later, with a perfect transition from my N4 to the new and awesomer G2. :)
[G2 General] claireth:
i also did the same mistake as you did and still i'm confused how to NOT erase the sd card in case of flashing a new rom etc...i also saw a little bit earlier that i have no recovery...nor stock nor custom (i restored my phone some days a go to fully stock) but i guess i did something wrong :p

well now i'm rooted and i want to flash CWM but my questions remain a)how to not erase the sd card and b)in case i want to return to stock how can i get the stock recovery??

ohhhh...seems that without an external sd i'm useless :silly:
[G2 General] lampardd:
Guys I'm stuck at Firmware Update screen which opens immediately after download mode..Anyone knows how to fix this?
[G2 General] daddioj:
after flash what message are you guys getting? pass. or later on failed even though the phone restores just fine?
[G2 General] hyelton:
When you see failed that's because you unplugged your phone before the countdown was finished. Part of that count down includes the rebooting of your phone which has nothing to do with the flashing part.
[G2 General] Akuma10:
TWRP

WIll this method work since I have TWRP as customer recovery? Thanks
[G2 General] daddioj:
i actually leave my phone alone. and it never reboot. but just fails and the end portion just sits at waiting for reset the whole time even if the phone is booted
[G2 General] donalgodon:
I'm confused, and my head is swimming.

Is the AT&T version E980 more difficult to flash a Stock ROM to?

All I want is to flash the Stock Panama 980H ROM to the AT&T version, but I'm getting bogged down by details that don't appear in other flashing threads on the device.

Can someone please help me understand!? I'm reading, and reading, and reading, but there seems to be some contradictory info here. :confused:
[G2 General] hurrpancakes:
I'm having some hardware issues with my phone, so before I brought it in to get it looked at, I figured I'd unroot and go back to stock.

While following the directions, I got to the last time you click ok, and wait for the process, but about 10 seconds in, I was getting an error saying "the phone is disconnected from pc".

I searched this forum, and found Semantics' posts:

I decided to try that, by just starting the process with my phone started normally, not in download mode, and it worked fine after that. Just wanted to share what happened to me in case others were having issues

Could some one help me. Pm me about this.

[G2 General] boyoboyo:
What happens if my carrier isn't listed? :(

Can I produce a .kdz on my own, somehow?
[G2 General] StreetkillnHD:
i finished the flash to stock processes and my phone rebooted with the att welcome get started screen.

and on the flash program it says

factory reset flag check fail??

[G2 General] shingers5:
just a quick thank you to all who contributed to this thread..........

in my attempts to get PA/CM going i managed to mess up my imei. i then flashed the .kdz for the E+988 and all is back to normal. just wanted to state that restoring my backup did solve the issue was i preferred a clean install free of gremlins :D

Anyone has alternative link for the TOT Tmobile Firmware .... its taking forever to download ...
[G2 General] hyelton:
No as All these are Hosted on my Server which is plenty fast enough.

Use a download manager. And remember the size of the file is LARGE and speed depends on your ISP or your connection.

EDIT: Speeds seem fine here, This is no where near slow lol
[G2 General] portis:
Tmobile .Well i can confirm the downgrade method doesn't work on virtualbox.I fixed it when installed win7.
[G2 General] hyelton:
I dont even think its supposed to work on a Virtualbox due to the drivers that the flashtool would see wouldnt be for the phone but for the virtualbox to read the phone.

Glad you got it :D
[G2 General] portis:
actualy im using usb host adapter and virtualbox sees lg phone.maybe it works but not flawlesly as on real win

[G2 General] mkil5:
I am on Verizon and did the OTA for VS98024 yesterday and my phone has been absolutely horrible since. Text messages take forever to send out (if they send out at all) and the battery life has been so bad that it actually loses power when charging via usb plugged into a computer. I used to be able to get over a full day of moderate use while never seeing a charger, now its about 6 hours of little to no use while using a constant PC USB charge.

So my question is, does this require root (am not currently rooted)? And will the vs98012b_00.kdz be what I am wanting to go back to what I had before the update ruined my phone? I have Verizon 32GB version.
[G2 General] hyelton:
The whole point of this thread is to go back to stock so no root is not required , the method here is what LG would use. And about the problems your having did you perform a factory reset after taking the OP?? If not that may fix your problem. Resetting after any major update is always recommended.
[G2 General] mkil5:
No, I didn't know that about factory resetting. I will do that before I try to go back to VS98012. However I talked to Verizon and LG customer support earlier today and they are supposed to be calling me back at any minute now, so I am going to hold off on the reset until then.

Hopefully that will fix it.

Thanks
[G2 General] hyelton:
I'm shocked that's not the first thing they told you. Verizon usually will ask you to do so even when its not needed lol
[G2 General] hyelton:
DId you try the TOT method? The TOT method is recommended for the T-Mobile Version
[G2 General] mackster248:
Thanks, trying it right now but I'm stuck at the final screen. It just says ready. Phone is already is DL mode and plugged in. What should I try?

It says failed and that device model is different? I downloaded the correct files for T-Mobile. Could the problem be is that I'm on a CloudyFlex ROM? Problem is, I flashed the CloudyFlex but forgot to flash SU so I'm stck on this ROM, that's why I'm trying to downgrade back and re-do everything.
[G2 General] hyelton:
Did you go into device manager and set it to port 41? and after doing that unplug your phone and put it back into download mode then plug it up after flashtool says its ready
[G2 General] mackster248:
Yeah, I changed the port to 41. I did that as well and plugged it back in and gave me this.

It says failed and that device model is different? I downloaded the correct files for T-Mobile. Could the problem be is that I'm on a CloudyFlex ROM? Problem is, I flashed the CloudyFlex but forgot to flash SU so I'm stck on this ROM, that's why I'm trying to downgrade back and re-do everything.
[G2 General] hyelton:
When it fails use the Megalock.dll file.

I`m confused at what your wanting to do go back to stock to root? You dont have to be on stock to root...
[G2 General] mackster248:
Thanks! I tried to apply the megalock dll file but it keeps saying wrong dll file and won't let me apply it.

I tried the ioroot methods but nothing works. I'm assuming it's because I'm on a custom ROM rather than the stock TMO KK ROM.
[G2 General] hyelton:
The reason why your post about root is somewhat confusing is because say You do Flash the KK Rom... Okay, Root it and load recovery. When Your in Recovery when you Wipe Data/Cache and format system before flashing your new rom Root should be lost. I have yet to run a rom on any phone that was NOT rooted lol, You sure the rom you have is not already rooted? Have you tried installing SuperSU from the market place?
[G2 General] mackster248:
The ROM has SU installed but when I try to update the binaries it fails. Lokie isn't identified. Then I try the ioRoot25 method but that's a nogo as well and nothing works. That's why I just decided it'd be best to downgrade since I've done it plenty of times before. Don't know why Method 2 doesn't work for me anymore. :(

Also, I have the white line issue with my TMO G2, so every time I flash an LG KK ROM I have to flash the official TMO ROM first (which takes off root and takes away my recovery) then I wipe and then flash whatever ROM I want. I was just forgetful and forgot to flash SU after the ROM so that I can easily re-install a custom recovery anytime I wanted via Cloudy's AutoRec. This was only way I can avoid the white line glitch screen.

For those of you who are new to this or just stuck, this video made it very simple (especially for newbies like myself). The video title says its for att but theres a link for t-mobile 4.2.2 download in the description, [MENTION=522014]SuperSport[/MENTION] just added the link yesterday. I just followed the steps shown in the video and I was done in no time.

youtube > watch?v=Lg693AYgoTo
[G2 General] hyelton:
The Download link in the video is basically the SAME method here.
[G2 General] quantum89:
Yea basically. All im saying is its set up alot easier, more "newbie" friendly. Not saying this method doesn't work.
[G2 General] hyelton:
Its the same setup, 3 downloads in one.

The only hard part of this thread is the Kdz method where most of the problems come from, The tot method works great :)
[G2 General] mkil5:
It is looking like the factory reset did work. Thanks!

Awesome! :highfive:

[MENTION=2607037]hyelton[/MENTION]

Man, tried TOT method again on a different computer and still the same issue. I have no idea what to do now, every downgrade method won't work for me. :(
[G2 General] hyelton:
Hi, When it comes to the TOT method Its more phone dependent than computer dependent, unlike the kdz method can be picky with the computer but the tot method is not.

You have a recovery installed at all? Can you install one? If so install TWRP or CWM and format system that should allow you to flash.
[G2 General] mackster248:
I don't have root access so sadly I can't install a custom rec, I'm on stock rec. I have the CloudyFlex ROM installed and can't root it with the ioRoot method. I'm pretty much stuck since no downgrades work. :/
[G2 General] expertzero1:
I had bender_007 help me with this same issue.

We're pretty much screwed atm until we can figure out how to past the security for root/recovery lol
[G2 General] mackster248:
Yeah.. Bummer lol. Are you stuck on a stock or custom ROM?

Just put CDMA and flash it

How do I check the com port in the device manager? I don't have a drop down for com ports.
[G2 General] npzinho:
On LGMobile Suport

True

If you can enter in /system, change model in build.prop or flash a D802 rom and do that and flash later.

True, but in LGMobile, it does that too, but doesn't show to us, shows only a ERROR

Sorry, I didn't follow.

What is? Stuck in 49%?
[G2 General] mackster248:
Yeah, I keep getting stuck mid way through KDZ. It says error at 49%. So I just have to unplug and does that each and every time.

I forgot to tell, I select "CSE web upgrade test" too.

[G2 General] expertzero1:

Didn't work.
[G2 General] npzinho:
It is hard to understand your problem one by one.

Including in another language, I'm brazillian.

:D

If you can "start" the rom or flash any other in (LGFlashtool) you just have to change the model name in BUILD.PROP to dll's model and flash it.

Did you try that?

Because in here, my device showed MODEL: G2 and works with CDMA/CSE Upgrade goes fine and worked.

My model was D805
[G2 General] expertzero1:
Cant change the build pro because it doesnt stick. Is there any other way to change the build pro than using an app. Root access doesn't work.
