LG G Pad - Return Back To Stock

This Guide is to Return Back to Stock.
This has NOT been tested Yet So do it on your Own Risk! The Files are STOCK though from LG`s Servers But this Method Should work if you have bricked your device.
How to flash ROM:
1) Download the Rom You Want! Choose your model At the Link Below - The Files are Hosted on my server for fast speeds!
Click Here
2) Download LG mobile support tool and Install it. (It will open up when its done just CLOSE IT OFF)
LG Mobile Support Tool Download
3) Download / Install FlashTool (R&D Test Tool) & Drivers
Download Here
4) Power off your G2, press Volume Up & Down key and then plug in the usb cable (enter to a download mode)
5) Extract FlashTool and run UpTestEX.exe
6) In R&D Test Tool window,
Select Type = 3GQCT (top left hand side)
PhoneMode = DIAG (top right hand side)
Select kdz file = click to select your LG stock rom *.kdz
Click "Normal web upgrade test" (bottom right hand side)
Then another window will pop up, click "Upgrade Start" button
wait a few seconds, another window "Select Country & Language" pop up,
=> Country=Republic of Korea
=> Language=English
you can click ok to proceed
7) All Done and wait for finish!
8) Be Sure that after flashing to perform a reset as for some reason flashing this does not remove what was there before until you reset. By turning off, Holding down power and Vol Down until it comes up on the screen.
If I helped you in anyway feel free to Buy me a Drink or click that THANKS button

I can confirm it works (i've done it twice to recover from unsuccessful CWM attempts).
The best way to get the stock rom would probably be the one explained in this thread http://forum.xda-developers.com/showthread.php?t=1073827 (it ensures you get the latest rom).

Thanks for the post really usefull .

Found some more detailed instructions
Method #1:
Tap your Apps icon.
Go in to your Settings.
Select Backup & reset.
Choose Factory data reset.
Method #2
Make sure your device is fully charged and turned off.
Simultaneously press and hold the power and volume down buttons.
When the LG logo shows up, release the power button only.
Now press and hold the power and volume up button while keeping your hold on the volume down button.
When the factory reset screen appears, release your hold on all buttons.
Press the power button to continue.
Press the power button again to confirm if you’re sure you wish to continue with the reset.

That program NO longer works , Requires an IMEI , and also The files I get come directly from LG servers so they are the latest and I always delete the older firmwares when they does happen. Theres a restore method out there somewhere thats a program but not sure what it was called.

DUDE! Thanks a lot!
You saved my day.
Had my pad in bootloop (don't ask ) and nothing did the trick. Even the complete new install. And nowhere I found info about how to enter recovery/factory reset.
Tried everything on my own, except this stupid combination you posted above
Long story short: Thanks :highfive:

Getting this error after clicking the Upgrade Start button:
Code:
Please install CSMG B2C Client TOOL
Select Tool -> B2C Client Setup menu
I've run the B2CAppSetup.exe and had the program pop up (incidentally, there is a way to restore through that - connect the tablet in download mode, then go to Options -> Upgrade Recovery), then closed it, and followed all the other instructions exactly.

Fixed

Hi Guys
can someone please help me with my G Pad. I was trying to flash cyanogen but something went wrong. I´ve rooted it with Kingo succesfully, then I tried to flash latest TWRP 2.6.3.0 and that is where I failed. I´ve installed it from terminal emulator but some errors occured. So I´ve tried doing factory reset, GPad rebooted and now it won´t start. I´m in a bootloop: LG Logo with classic secure booting error and then it loads TWRP, but it only runs a script (see photo), and then reboots.
So now works only adb (not fastboot) and download mode. I can not reinstal recovery via adb and LG updater is allways stuck at 4%. I´ve tried V50010A_00.kdz and V50010E_00.kdz multiple (many) times on 2 different laptops but it allways ends in
********* 2Chip Model.dll input Parameter End*************
09:26:54 : wParam : 100, lParam = 72
09:26:54 : MODEL DLL Event : (100, 72)
09:26:54 : Step : TYPE_WPARAM_UPGRADE_ERROR
09:26:54 : CleanModelDll() : Free Model.dll
09:26:54 : _DetachDLL Call
09:26:59 : _DetachDLL Call End
09:26:59 : Page_Error şÎşĐŔÔ´Ď´Ů
09:26:59 : ż©±â´Â Retry şÎşĐŔÔ´Ď´Ů
Hard reset only loads TWRP and bootloop continues.
So please, I would be very grateful for any suggestions.

If you actually read the TWRP thread you would have known that 2.6.3.2 is the latest, and that 2.6.3.0 doesn't work with CM/AOSP ROMs.
You need to follow the returning to stock guide.

Well I downloaded TWRP for my LG G Pad from TeamWin site and the only recovery was openrecovery-twrp-2.6.3.0-awifi.img. But I could´ve dig in it a little, usually I´m very careful and it´s my own fault.
But can someone give me advice what to do with my "back to stock" guide? I´ve already followed this guide X times, but I´m still stuck at 4%.
EDIT:
After 3 long days I´ve managed to overcome my 4% stuck problem. After hours of reading tens of threads I´ve tried almost everything: changing COM ports, reinstalling drivers, reinstalling LG mobile support tools, manual flash with LG , PC suite, LGNPST, installing new windows 7...
After a while I understood that the guide for back to stock recovery is OK, problem was in the extraction of the KDZ file. My Windows 7 couldn´t for some reason cooperate well with any of LG flashing programmes. So then I installed Windows XP. Nothing to lose.
It worked flawlessly! KDZ extraction process was taking significantly longer and then flashing process went trough magical 4% stop and now my GPad is like new.
So the solution for me was to install Windows XP and flash from it.
I hope it will help people with this flash stuck at ... problem.

Download TWRP in flashable zip and flash the newest twrp. Also download ROM and flash it after twrp. If twrp just runs script and then restarts then you have to do a return to stock. TWRP did the same to me too and had to do a return to stock.
When you do a return to stock make sure you click where it says web upgrade. That opens a new window and that's where you start the upgrade. I got confused there...

Thank you for suggestion.
So your advice is to flash TWRP and ROM, then do return to stock?
I would have already flashed new TWRP but the fastboot is not working for me (don´t know why, just says waiting for device) and until now i haven´t found a way to flash recovery via adb from recovery. Or to enter full TWRP.

Sounds like return to stock is your best bet then.

You can try to flash the GPE ROM port and see if that works. Would be helpful in figuring out what's wrong if you do not have working WiFi and Bluetooth.

[Q] [FIXED] Enter your PIN/PASSWORD to decrypt

I just updated my lg g2 recently, but i had an problem just after entered the PIN sim card! A blank page showing with a text and textbox saying "Enter your PIN/PASSWORD to decrypt"! I'm sure that before update i didn't enter any password.
And when i search i find that i can go to Factory Reset, But i follow the steps to go Factory Reset. I'm getting just logo LG and then my phone restart again,
if you had any idea how can i fix this problem, it we'll be great!
Thanks XDA Members.
[FIX] : There is no other solution, You should just Flash by using Factory Reset, And in my case i can't access to factory reset, I used the LGFlashTool method.
Thanks for every one who helped me.

Pretty sure you'll have to kdz flash.

What method are you applying to go to factory reset?
Proper method:
Power the device down.
Press and hold the Volume down button and the Power button.
When the LG logo is displayed release the Power button only then immediately press and hold the Power button again.
Release both buttons when the Factory hard reset screen appears.

Support inquiry
Hi Swizzle82
I would like to ask for the same ...
LG G2 32 GB from HK , today made update by LG PC Suite to software ver D80220B, after restart I stocked with PIN/ Password to decrypt inquiry ...
What to do ? I have followed your suggestions but it doesn't work ..
Frankly speaking I have only tried with D80220A ver , to downgrade the phone
But after switching to LG Mobile , it still downloading the newest version again - the effect after restart was the same , inquiry for PIN/ Password .
I have noticed that after switching language and location from Poland to Korean Republic - it showed in LG mobile support tool , two options ... one of them was to get your PIN - but unfortunately I need to register and www was in Korean ..
Any ideas , hints - I will appreciate your kind support

Same problem here.
I'm on the lg g2 D802.
Initially I did it using the LG Flash tool method, however, I did not get the region and language pop up. So I proceed to flash it from the lg support tool.
When I had done this previously (at around the time of the official kitkat release) I had gotten that pop up and all had gone well.
But this time perhaps because of the me using the lg support tools directly, it is now asking for password/pin to decrypt and the hard reset key combinations don't work.
Could this be because I'm currently using windows 8 and I was earlier on Windows 7?
Thanks in Advance

Problem Solved (Sort of)
Earlier when I was using the Flash.Tool.1.0.54, it wouldn't ask for region and language in the pop-up. It would just open the LG Mobile Support Tool and then I manually selected the Start Upgrade button to flash the phone. The problem with this was that on boot it would ask for pin/password. I couldn't even boot into the stock recovery for some reason.
Then I used the LG Flash tool 2014: http://forum.xda-developers.com/showthread.php?t=2797190
There was a region and language pop up and it proceeded to install the firmware.
But on boot, it still asked for the pin/password. So I tried to boot into and it worked this time! Pressed the power button 3 times and it wiped my phone.
On reboot, the phone worked perfectly without asking for the pin/password. But, now it was reading my internal storage as only 16GB. Thankfully there is a solution to this over here: http://forum.xda-developers.com/showthread.php?t=2470207
It worked perfectly for me.

Well, I'm using a L50 d227, I've done everything from Vol down + power >> factory reset >> erase user data to LG flash tool, downloaded kdz for my phone, flashed it sucessfully and when it boots, it asks me for a pin to decrypt.... HELP!

bricked my phone ?

Hello,
i got my LG G2 today and i rooted it no problem and i was able to boot into recovery, but after i installed a newer version of TWRP i must have done something wrong now there is no TWRP there is only factory reset and i keep getting "security error" on boot up and cant get past it, i can get into firmware update but i tired to update it and it starts the update well it downloads it and notting else happens after this please tell me there some way to fix this

One suggestion? Don't mod or root your new phone the first day, you MUST use it for minimum two week with stock rom LG. ( according to me )
But getting back to your question, I also had your same problem. And I solved with LG's Launcher (computer program), I made a reset using a KDZ already downloaded.
Download The Appropriate Firmware file and Extract the zip, if required. Download and install LG support Tool.
Download and install LG Flash Tool. Download LG G2 USB Drivers if you need. Turn off your LG G2 and boot into Download Mode, press and Hold Volume Up Key and Plug in the USB Cable. Extract the LG Flash Tool and double click the UpTestEX.exe
Once the Flash Tool is Open, Change the select type to 3GQCT*and change the phone mode to DIAG. Click the select KDZ option file and select the .KDz extention file from the downloaded firmware folder.
Click Normal Web Upgrade Test. Now wait a moment and you will see a pop-up window, showing you the phone information. Click Upgrade Start Button. After a few seconds, there will be another pop-up asking you the Language and Country. As country, Select Republic Of Korea and Language English. Finally click OK to proceed the installation. When the Flashing is done, your LG G2 will reboot, don’t forget to do a Factory Reset. To do it, press and Hold Volume Down + Power Buttons until you see the Phone screen.
Try. Good luck

Are you able to boot into stock recovery? Also, are you sure you flashed the correct kdz file? If download mode works, just re-flash. You should have taken the backup of internal storege BEFORE flashing.

Check the box of the phone if you still have it, that should help you get the exact model of your phone. then try flashing the appropriate kdz.
