Tablet: Security- activate unknown sources, Developer options - USB-debugging enabled
Computer: download and install USB-drivers for LG G Pad 8.3 http://www.lg.com/de/service-mobil-telefon/lg-G-Pad-8.3

1. Root with Tovelroot V2 http://towelroot.com/
2. Install SuperSu v2.00 http://forum.xda-developers.com/show....php?t=1538053
3. Start SuperSu and Update Binaries ( normal)
SuperSu says failed to update Binaries please reboot, rebooted
after reboot Supersu works fine.
4. Install SdFix http://forum.xda-developers.com/show....php?t=2684188
should work without problem, if not you have a problem with root.
5. Install Flashify http://forum.xda-developers.com/show....php?t=2349847
Backup kernel & recovery , just in case.

I did NOT use this to flash the new recovery, but later on to enter in the new recovery

6. Download the newest version of TWRP for v500 from here http://forum.xda-developers.com/show....php?t=2551499
Attention !!! you have to take the one where it says:" These builds are for the 4.4.2 bootloader"
download new version 2.7.1.0 !! 4.4.2-v500-TWRP_2.7.1.0-recovery.zip !!
copy the recovery.zip to your tablet
7. Download the tool to flash recovery from here http://forum.xda-developers.com/show....php?t=2698267
look at step 3 , download: V50020_aboot_twrp_v2.zip, to your computer and unzip it.
8. Connect the tablet (MTP) to the computer and run file:runme.bat, ! on tablet you have to allow acess from the computer and SuperSu acess for adb !
when finished disconnect usb and let the tablet reboot
9. On the tablet start Flashify , in the menu press: reboot to recovery
10.Tablet starts to the TWRP-recovery. Now go to:install and flash the new version of twrp(2.7.1.0) that you have copied to the tablet.
reboot system.

this worked for me.

Edit: For all who have the new V50020d firmware
you have to modify the runme.bat file before you run it!

Have a look over here, post 72

Just got my G pad, and let the OTA update to 4.4.2. This procedure has allowed me to get TWRP going. Awesome!!! Thanks!

I change the lines on "runme.bat" file:

echo Stock LG build KOT49I.V50020a\V50020d

and

if %FWVER%==4.4.2 (
if /I %MODEL%==LG-V500 (
if /I %FWBUILD%==KOT49I.V50020a (
GOTO CheckSU
)
if /I %FWBUILD%==KOT49I.V50020d (
GOTO CheckSU
)
)
)

I have done everything in the guide after rooting, took another aproach for that, and after changing version in the runme.bat even that worked. But now when i try to boot to recovery i get a error message and now I dont know what to do

The error message is as follows:
Secure Booting Error!
Cause : boot certification verify

The tablet just stops here so I then have to hold power down to turn it of and then turn it back on and i get into the normal bootlopp and in to android. What to do?

My specs is they mather: Android 4.4.2, Kernel 3.4.0, Versionnumber KOT49I.V50020d, Software V50020d.

Thanks from a noob!

Hi there, I've recently bought g pad 8.3 and rooted very easily with towelroot, installed SuperSU and flashify but I'm struggling to install TWRP 2.8.0.0.
The main problem is that I'm using Linux so instructions for windows don't work on my computer. Does anyone have any suggestions?
I'm on software version v50020b and kernel 3.4.0. and use an Ubuntu based linux.

Thanks in advance
