According to this the factory image for the LG G Pad X II UK750 is "Android 6.0.1 Build MXB48T" the same android build as the Pixel C (ryu), it seems to me that it should be easy to compile a factory image for the UK750 using this build, to flash via fastboot and unlock the bootloader, I would think the twrp for the Pixel C would be compatible as well as the supersu, anyway this what I found.

Good morning
I have:
LG G Pad 8.3 with LG's custom interface OS
Android version 4.4.2
Kernel version 3.4.0
Build number KOT49I.V50020b
Software version V50020b
Here is an image of the software information:
http://s30.postimg.org/taiyvu2k1/2014_06_28_14_31_41.png
I have already:
The LG drivers installed and updated -
Rooted the G Pad with towelroot's tr.apk (many thanks to the guy who made that method!)
Root checker and SuperSU installed and verifying the device is rooted
Google USB drivers (after rooting, the device refused to be recognized through the USB - installing the Google USB drivers seemed to fix that, although occasionally it dissappears again and I have to unplug/replug the USB cable)
Google ADT Bundle (adt-bundle-windows-x86_64-20140624 - although to be honest, my knowledge of using this program is limited)
Flashify (and Rashr - uncertain which is best to use, although both look good)
My goal:
Install TWRP
Use TWRP to install Cyanogen Mod
I'm using Windows 7 64-bit. My G Pad has a micro SD card, which it can also write to (thanks to the G Pad being rooted). I'm a competent Windows and Android user, but by no means a hacker. If I want to upgrade or fix something, I read read read and try try try. But installing a new OS on my tablet is a new experience and I don't want to turn my tablet into a permanent brick! I have done all my homework, and think I know all the concepts, and generally the procedure. Now I just need the specific files and procedure for my G Pad.
My questions are:
1) Which TWRP recovery/boot image should I use to flash my device? (I tried a version, and briefly turned my G Pad into a brick! Fortunately I tried some power+volume combinations that I discovered, and that seemed to return to the original system.) My best options I have found seem to be:
http://forum.xda-developers.com/showthread.php?t=2551499
plus using step 3 here (a loki-exploitable ABOOT and TWRP)
http://forum.xda-developers.com/showthread.php?t=2698267
...or only:
http://teamw.in/project/twrp2/213
2) Do I need to use an aboot/loki file first? (Apparently 4.4.2 doesn't have a loki exploit? I'm a little unclear about this tbh.)
3) Can/should I use ROM Toolbox or ROM Manager?
4) If you try to flash a TWRP, and it doesn't work, does/can the device just return to the standard OS? (This is what seems to have happened with my G Pad.)
5) Should I wait until the community has more experience TWRP-ing and modding the G Pad Kit Kat 4.4.2, V50020b device? (There seem to be a lot of posts with people installing TWRP and installing another OS.)
Many thanks in advance. And while I am decent with computers and technology in general, I humbly ask to speak/explain it to me including steps you probably already know are obvious(!) - I don't want to miss anything, and it is probably not obvious for me, as this is more or less my first time! If I can make this question clearer, or can provide better information, I will update this comment. Again, many thanks in advance!
This TWRP worked for me http://forum.xda-developers.com/showthread.php?t=2641409 and for version V50020b.
With this recovery you can flash LG based ROMS like LRS G Pad http://forum.xda-developers.com/showthread.php?t=2621904
If you want to install an AOSP based rom you have to downgrade to a 4.2.2 rom or bootimage http://forum.xda-developers.com/showthread.php?t=2621904 (flash the 4.2.2 zip from recovery , reboot again to recovery , and then flash CM or AOSP based rom)
Thanks!

Thanks for the links and information! I don't have time to try yet, but when I do, I'll post the results.
Hi, All. Ive followed XDA for a long time and love it. I love my verizon G-Pad but ever since the Lollipop update it has just been so slow and almost unsuable. Well ive got good news. Today i found a way to downgrade back to LG Official Kitkat 4.4.2.
Tool Used: LG Flash Tool 2014 - you can download from this thread
http://forum.xda-developers.com/showthread.php?t=2785089
I could only get this to work from LG's Download Mode (with tablet turned off, hold the Vol Up Key and plug in USB cord)
If you are running version 23A Lollipop you must downgrade to 22A first. Attempting to downgrade straight to 11A (Kitkat) will fail at 57% restore.
After downgrading to 22A, allow the device to fully boot then shutdown and return to download mode
Now push 11A firmware, everything should now go smoothly (at least it did for me)

Many Many thanks to the Devs of the LG Flash Tool for such a wonderful utility on LG Devices
tutorial?
How do I downgrade to 22a?
In the Firmware download link I've provided is the 22a and 11a firmwares. Follow the LG Flash Tool link for usage.

Hey man gotta question, my pad was on lollipop and only rooted with no real tweaks and I rebooted one day and it sticks at the Verizon logo. I can get to stock recovery where any selection goes to fastboot where any selection goes to a blank screen where I have to kill it. The couple others I've seen with this problem had success with the support tool / update recovery deal but mine says everything is up to date. I tried flashtool with a kdz and I get all the way to it supposed to send it but the tab download stays at 0% and nothing happens....I would rather have kk anyway would it be worth trying this , **** can't hurt the damn thing no worse lol tired of it sitting in my dresser where its been for months ...I really wonder wtf happened to it
EDIT...... OK I feel like a real dumbass lmao... Apparently the pc I was using had an Antivirus on it and apparently the flash tool doesn't play well with an Antivirus
OK has anyone found a twrp that will flash correctly on the vk700? The twrp floating around for gpad 10.1 only works on the v700 cuz its been bumped To work on the locked bootloader....

Does anyone know if it works on v700 ?

Well this downgrade is for vk700 not v700 which is a big difference, I found that out by trying to get twrp to work on my vk700 when it's only for v700 which if you have the v700 your better off

I tried to root the tablet using KingRoot (which worked) then tried to replace it with SuperSU (which did not work) and some how things got all jacked up. Now when the tablet boots, it give an SUID inconsistency error. I tried to factory reset it to see if that would fix it, but it didn't. I'm looking to find a way to get a factory/stock image and flash it some how. I searched around on the forum and didn't really find any definitive answer. Would I use something like LGUP or something alike to flash a stock image? I have the stock recovery as well.
If you found a KDZ you could use LG Flash Tool 2014 to flash it from a Windows PC. I haven't fooled with LGUp much because it doesn't support as many devices as LG Flash Tool 2014 and I don't think I could get it to work on either the VS985 Verizon G3 or VK810 Verizon G Pad 8.3. That said, it wouldn't hurt to try LGUp if you found a stock image to flash, but I won't be surprised if you'll have to go back to using LG Flash Tool 2014 instead.
Do other versions of the G Pad work with the 8.0? Such as the 8.3 (v500 I think) for the KDZ image? There is a KDZ image for every other variation of the G Pad except for the v496, that I can find at least.
Also, does anyone know if TWRP will fix permission issues? Realistically, I just keep to reset the SUID's back to what they were originally. I just remember older recovery's having the option to fix permissions.

Not that I know of. I don't know if either LG Flash Tool 2014 or LGUp will even attempt to flash a KDZ meant for a different device than what you have connected, but if they did there's no guarantee it wouldn't brick your device and it likely would. The G Pad 8.3 has three variants, all the KDZs for them are incompatible with each other as far as I know: VK810, V500 and V510.

You can find root for your device under XDA forums. It will be some kind of script file. When you run script, it will automatically unlock your bootloader. After that, you need to flash custom recovery. After this point, you are able to install custom roms. Remember, gather all necessary files before doing anything e.g. Your device kdz firmware or tot firmware files.
dear sir i tried and i stuck on boot, so please guide me with the tutorial
its been hard to flash any custom rom on this device
my model is d686 , its not d680
so try to give a simple tutorial to flash rom this device, its very hard to boot into recovery menu and secondly the recovery menu appears only once because after flashing the rom i stuck on boot logo and nothing else
please help me
and also make any rom which is suitable for this device so we can install on it and use it without legging
thank you
Honestly in the long run getting a newer phone like a nexus 6 will fair better. This phone was an absolute pain for me to manage and ROMs were always crashing left and right. After switching to a nexus 6 I do not regret it.
I've been trying to resurrect an unhappy LG G Pad v510 palman. I can boot it, I can flash it, I can get to fastboot, I was able to install twrp-3.1.1-0-palman... but whatever img files I start with, I can't seem to run the OTA successfully (I get the android flat on it's back with the red error icon).
I'd be happy starting from an old version and manually running successive OTAs if it meant I was back on an upgradeable path.
I'd be almost as happy flashing a recent OS version.
Anyone able to return a v510 to an OTA friendly path?
