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

09:26:59 : 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.

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

[Q] Completely lost my device? (After flashing some ROMs)

Hello fellow people...
So, my lovely Android (LG P700) is stuck in a bootloop. So, here's the story of my phone:
1) I bought it and eventually managed to root it.
2) The same day I installed CyanogenMod 10. Everything worked so fine.
3) Later I upgraded to KitKat prime (Based on CM11). Pretty darn fine, but it was laggy like hell.
4) So I decided to downgrade back to CM10. It worked, BUT THEN - it ignored my SIM card completely and when dialed *#06# I found that my IMEI got torn off my phone.
5) So I installed AOKP KitKat. Was REALLY good but it didn't have some crucial-to-me options, so I found somewhat tasty...
6) And I installed the Pac-Man ROM. And something went quite wrong, because it only booted every third time, else it gave black screen, but everything worked really fine. But later, I noticed that Wi-Fi won't turn on, so guess what...
7) AND WHAM! MY WORST MISTAKE! Wait for it... I decided to install the Phenom kernel (Idiot me, it was made for CM10...), TADAA!
8) After the LG icon it gave me 3 random stripes distorted and pink in color. And the recovery is nothing but black screen.
9) So I tried to flash rooted v20d kdz to it... Nope. Only stuck on stock boot animation and the three button combo won't work, no recovery, no black screen, no data wipe option.
10) I used the official KDZ updater... Same sh* as 9).
11) Tried flashing rooted v10k... NOPE, the flasher is throwing the error: WParam: 4, IPARAM:1002.
NOTICE - Yes, I did data/cache/dalvik/system wipes everytime when I upgraded my ROM/changed kernels. I also used GApps every time.
Anyone can help me?
Thanks in advance!

I had almost the same problem yesterday. My phone could go to emergency mode. If yours too then try this. Download the V20a ROM with root and CMW (it's really important to use this one): http://forum.xda-developers.com/showthread.php?t=2214717 (thanks Homero2 so much!),
- Installed the msxml file in the KDZ folder
- Run KDZ_FW_UPD.exe as administrator
- Set it to 3GQCT and DIAG, open the V20a kdz file and press "Launch software update"
- I still got a lparam error, but here's the great thing about this ROM. Even though I still got a bootloop, I MANAGED TO GET INTO RECOVERY! Instructions: Press the power button and the volume - button at the same time. When capacitive buttons turn up, press the menu button. When LG logo appears, release the power button. (REMEMBER: VOLUME "-" BUTTON AND MENU BUTTON NOT HOME....
- Recovery shows up.
- After that, I pushed a downloaded ROM (zip file) to my SD card and installed it via CMW succesfully!
Use CPA rom for p700/005 this time, it bugless and remember to factory data reset.
Hope it helps you!

Thanks a lot, but... recovery won't turn on, everytime I try to push vol-/menu/power button combo nothing happens and the phone tries to boot up as it would normally leaving it in an infinite bootscreen... Btw, my home button is broken and the vol- button is brokenish and I need a few tries to press it normally AND the captive button lights, well... they won't turn on anytime, just dark touch-able areas and that's all. I'll try to get to recovery though.
EDIT: BTW, you sure it's DIAG not EMERGENCY?

Ive tried to boot it into recovery but it wont work when i press the buttons (home and vol. down). Im freaking out, and ill admit it im just an ameture and didnt really know what I was doing, but I just got this phone as a replacement for my stolen phone and my parents will kill me if we have to pay a fortune for sprint to fix it if they even can. im using the latest version of twrp I think for the ls980 but it wont let me boot into it. help please as soon as possible. thank you!! Hopefully people still watch this forum I know its a little dated

help with LG G2 D802 - no recovery working, download mode only

Hey, for the record: I wanted to flash CM13 (including Gapps Pico) on my LG G2 (did before some Nexus 4 and 7, worked) ...
-- went through instructions on CM-Homepage
-- DIDN'T know what to do with loki-tools!? --> DIDN'T do it, might be the problem!?
-- went on with USB-Debugging, ioRoot (manually, since the ioroot.sh didn't work), AutoRec (since FreeGee doesn't work with 4.4.2), booted into recovery by tapping button in AutoRec
-- booted into recovery (was then twrp 2.7.0), wiped data (factory reset), pushed cm13 (NIGHTLY-d802) with adb, installed it --> everything worked fine
-- pushed opengapps-arm-6.0-pico with adb, installed it --> everything went fine
--> NOW: tapped "reboot into system" --> but won't boot anything!!!
-- when I start normally, it shows LG-screen 1-2 seconds, then black/dark-grey screen (phone is on! but black screen, not as black as if off!)
-- when I start into recovery (volume down + power) --> same thing
-- when I plugin USB-cable, then phone starts with LG-screen 1-2 seconds, then flashes this dark-grey screen every 1-2 seconds but doesn't connect normally ("watch lsusb" on linux-shell shows device everyonce in a while: "Qualcomm, Inc." and a certain ID)
-- after these 3 possibilities I can switch off phone only py pressing power around 10 seconds (if I hold only 7 seconds, when the screen turns black for off, it restarts)
-- I can boot into Download-Mode (Volume up + USB-cable), but don't know what to do with it ...
-- I found this thread for going back to stock firmware, but I don't have windows PC AND DON'T KNOW whether it is right thing to do!?
-- Found also the correct Firmware on this page (Model: LGD802 - -Latest Firmware: D80230F_00)
--> Are there any other possibilities to get back to a working phone!? Especially versions for linux!?
Thanks a lot in advance!!!

Hey, got it solved. My conclusion:
- virtual machine on Ubuntu doesn't work -- can't communicate with device -- windows machine worked
- usb3 doesn't work, use usb2-ports
- how to get into recovery-mode wasn't clear for me: https://www.youtube.com/watch?v=jPUTImVEHqc (push Volume DOWN + Power -- when LG appears, leave them for 1-2 seconds -- then press them again)
- CM13 NIGHTLY doesn't work with LG D802 (also tried flashing blastagators build since AutoRec works (with KK) but is outdated)
- if using tot-method, one can extract the tot-files by executing the .exe
Now do have a CM12 on my LG and everything works fine...

Try this! works for me on cm13
Recovery:
1 Power off your device
2 Press and keep pressed Power and Vol- until LG logo appears
3 When the logo appears release all buttons and press Vol+ and Vol-
4 Choose Yes navigating through the menu using the volume and power buttons
Download mode:
1 Power off your device
2 Keep pressed Vol+ and insert the usb cable
