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 !! 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( 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

change the V50020b to V50020d, dont forget to save the file.
Thanks so much bro this worked perfectly, I was already rooted with ioroot25 so I just started from step 4 and everything went as planned
