LG G Pad - Return Back To Stock

[hyelton]

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.

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).

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:

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.

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.

Edit: In fact I´ve never even got to install cyanogen. I was still on stock when tried to factory reset.

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.

hi, is there a rom stock flashable with TWRP?

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.
