I am trying to flash a 16GB D802 back to stock, but when launching the R&D test tool, it asks me for "Country", "AD ID", "AD PW" and "Employee Number". Clicking OK brings up an error message.

How can I get the tool to launch?

I have an ATT (d800) I had the OTA (v10o) installed and I accidentally reinstalled v10o with the flashtool. I was wondering if the LGD800_20130904_LGFLASHv160.dll DLL will work for the v10d also or will I need a different DLL?

The only reason I want to go back to factory shipped is none of the roms seem to like v10o even after I have root and recovery installed?

Hard Reset to cure boot loop

I have experienced this after flash it. Everything is okey but after restart, the phone is bootloop.

1. Push Power Button to shut off the phone. Make sure totally shutdown and no boot loop

2. Hold Press Lower Volume Button and then hold press Power Button

3. Once LG logo shows up, Release Power Button and hold press Power Button Immediately

4. Hard Reset Verification will be shown and confirm by pressing Power Button

5. For me there was two verification before the machine do hard reset

6. The machine starts up normally

Good luck

My experience reverting to stock

I had a little trouble using this method reverting to stock (ls980). I got stuck in a boot loop flashing PA. When I used this method I would get "Incorrect DLL" message even though I do have the correct DLL file. However, luckily, I made a backup of rooted stock. For some reason it worked when I restored my backup of stock/rooted. Works great now and in download mode it shows unrooted.
[G2 General] ROne21:
My phone is stuck on recovery boot loop after an OTA update. I'm on TWRP, TMo….I did a back-up before updating just in case but I can't even do a restore now. If I follow the procedures here and go back to stock, will I still be able to restore my back-up? The back-up is in the phone only as I did not bother to make a back-up in my PC. If not, is it still possible to extract that back-up and transfer it to my PC? I just want to save my pics in the phone……thanks in advance.

[G2 General] Iniesta89:
Hello guys,

I need some help. Yesterday I received my new LG G2 D802 which ive imported from Hong Kong. It came with "d80210f-466-92" rom and ive been trying for hours to change it to a dutch or european rom but it wont work.

I did a factory reset through the menu and installed the LG Mobile Support tool and the drivers. Ive been running UpTestEx and it seems to be running the update but after turning on and doing a complete wipe (with the down button and powerbutton) the rom remains the same. Ive been trying this with the European rom and the dutch rom but no succes. After the update it starts up in chinese/korean or idk what language that is and the rom remains "d80210f-466-92" . Does someone know what might be the problem?

Ugh I absolutely cannot get this to work, it stalls out at 49% every time. I have tried 3 separate machines, my one at work, at home and brand new clean virtual machine with Windows 7 on it. Every time it will not go past 49%. I have also tried flashing to another ROM first to see if that helps, but neither wants to work. I'm on the D803 (with Beanstalk atm) and am trying to flash the Telus image. Any ideas? The last few lines of the log are as follows:

Thanks guys. I've tried flashing back to a stock D801 image (even though I'm D803), no success. After I did that, the LG Mobile Support tool will no longer even try to flash. It just tells me that my software is up to date. Tried flashing CM11, same thing. Tried wiping the virtual machine clean, starting from scratch and same thing. Beanstalk seems to run good on it but I'm trying to get it back to stock so I can sell it. Not sure what else to try anymore, bah.

Hi guys, if I am on stock rom but rooted, do I have to do everything in the OP? Is there a way to just unroot my D802?
[G2 General] nickelfault:
Soooo I did this on my D803 which was a terrible idea, and now it thinks it's a D801, even after flashing a different custom ROM (Beanstalk). I've restored a nandroid backup and it STILL thinks it's a D801 - is there any way to full revert this stupid decision I made? I've tried flashing PA for the D803 and it tells me it won't install because I'm using a D801... I've flashed this version many times, but after making the above mistake, my phone is having model confusion issues, lol.
[G2 General] abdel12345:
I think you can just edit the build.prop using ROM toolbox and change it to d803 again

Does build.prop survive between flashes? EDIT: Checked it, and don't even see D801 or D803 listed in there. Looks like it doesn't survive between flashes because it has a bunch of ROM related settings in there.

I FINALLY got this to work!! After wiping every partition on the phone except my internal storage, the progress FINALLY went past 49%! So if you are stuck at 49% and are able to get into TWRP, wipe away! I think the system partition was the kicker here. I really hope this helps somebody else. I spent about 15 hours trying to get this damn thing back to stock. Now to sell it!
[G2 General] apvikes28:
Be careful. I wiped too many things by mistake and wiped out my efs. Make sure you have followed some of the other useful guides on backing up your efs. I was successful in this flash but had no network values and lost my imei.

Hi all,

I've a little question about different firmware versions: I've a D80210e-ESA-XX firmware, can I overwrite it with a European or Italian firmware?

I'd need it to enable the LTE connection that is not available in korean firmware version, so I'm looking for somebody who did it (just to be sure that I won't brick the phone).

Thank you so much for you precious help.

[G2 General] II_DiE_4:
Ok guys.

I think its not the CM11 that helps resetting the flag to UNROOTED.

If you wipe everything from custom recovery and flash .kdz file it will stay ROOTED..

What i did is after the .kdz is flashed and booted just power off the G2 and press Vol- + Pwr to do the factory reset from the stock recovery.

That reset the flag.

But im not sure its this the solution. Either way its another suggestion to try
[G2 General] gunnyman:
I tried that each time and the only thing that set mine back to unrooted was installing CM11. I have the D801
[G2 General] hyelton:
Yes Please Check the storagecow link in about an hour I have some errands to run real quick. It only takes 2min to upload.

My StorageCow site does not have any speed issues.. its on a 2GB internet port no speed issues. The LG servers are Slower and unrealible thats why I have them on my server, On LG servers they like to change the links or have a ton of downtime. All my links are offical as it gets! Also the SamMobile site was not official to Samsung. If your download is slow check your ISP and be sure your using a Download Manager Usually that Helps:D

Gotta Love Samsung for KNOX! lol.

That LG-Firmware site is junk. Yes they provide the firmware, but if you look they are advertising and making money on links they dont own/host(they`re making money off LG Servers) Not there own.. Yes I have ad`s but I`m hosting the files on a server I pay good money for. The person running that site is making money and pockinting it. That persons site prob costs them less than a few $ a month. It would be different if they werent taking LG`s Resources.

:( Bricked after accidentally installing an D802 ROM on my TMO 801. Can't get back to Stock, process fails @ 50% - "upgrade stopped due to an error" and within the process I see

[G2 General] abdel12345:
Thanks for sharing. So when it says factory reset it actually goes into recovery. Interesting. Maybe because the stock recovery is used to factory reset and its replaced? I'm getting my g2 on Wednesday and I'll make sure to make a backup first thing of stock ROM kernel and efs just in case.

I'm assuming I'll need to unfreeze apps and unroot before flashing, right?

To be successful in terms of a clean flash (and avoid issues) it is necessary to wipe EVERYTHING first in TWRP/CWM.

Well, I only ever rooted. I don't have a custom recovery installed, or ROM.

Use the Factory reset then flash. Simple.

Too late. If anyone else has the same issue, you'll need to perform a factory reset through the stock recovery (that is if you're only rooted, on stock), after flashing anything earlier than 12B (with the OP's method). If you try and do a factory reset through the OS, you find that after hitting the lock screen, services start crashing left and right. After doing that, you can accept the 12B OTA. This is for the VS980.

Very frustrating tool ,when it won't even work in windows 7 or 8 !

Spend hours to look for an alternative , but it seems their isn't one.

hey man. i tried to UNROOT my LG G2 using the kdz file from the StorageCow site through the download mode.

my phone bricked after doing it. which part i did it wrong?

my phone is Korean model with K version (F320K). and my firmware was 4.4XXX something and its kitkat.

one thing i noticed during the process of flashing using LG UpTestEX is one out of the hundreds lines scrolling down is something like this:

"ICS to JellyBean.... "

i think this might be the prob. but im not 100% sure. any tips to UNBRICK it?

i couldnt fine anyone else in the thread with same model (Korean, 4.4.X, KitKat, K version - F320K) has the same prob. really appreciate your help. cheers!
