DISCLAIMER: I or anyone mentioned or linked in this thread are NOT responsible for anything destructive you do to your tablet.

I am posting this thread because I am one of the people unable to root or boot my VK810 tablet with SuperSU access into a 35A rom. This thread will be mostly taken from threads already posted for this tablet. I am mostly using their hard work and just changing the process a little to get it to work for those of us that need a different way.

I have permission from [MENTION=2560614]roirraW "edor" ehT[/MENTION] and [MENTION=5022682]Hnk1[/MENTION] to use and link to there work and threads. I will credit others as I go. I am mostly posting links to threads and not to direct downloads in case the OP's change something on their end. (thanks [MENTION=2560614]roirraW "edor" ehT[/MENTION] for the info)

These are the threads I am working from;

It will seam like a lot of work but once set up it only takes about 30 minutes or so to finish. I could not get 35A to root with any method I tried ( and believe me I tried) or boot with supersu. So my method includes KDZ'ing back to 24A. Sorry

First things first;

Make sure you have installed working ADB

After you have ADB working create a platform tools folder inside the ADB folder and extract the platform tools there.

Copy and past TWRP into the platform tools folder

Copy and paste 4.2.2 aboot img into the platform tools folder

Extract LG Flashtool 2014 anywhere you want and set up.

Move the 24A KDZ file into the flashtool folder.

Now put your phone in download mode: power off, Volume down and plug in usb cable.

Open LG flashtool and follow the steps. If you have trouble refer to there thread for instructions.

After a few minutes your phone will reboot, go through the setup.

Once you are into the system put these files onto your phone:

35A rom

Stump root

4.2.2 aboot img ( rename to aboot.img)

SuperSU zip

35A aboot zip needed later to boot back into 35A rom

CWM recovery zip

Once all that is done root your phone with Stump root apk, you will need to allow unknown sources in settings and once stump root is installed you need to brute force it. It will take a few minutes but works perfect. Once you have rebooted to root the tablet go to play store and use one of the root checkers there to verify.

If already on 4.2.2 skip the first set of commands

If you have problems with these commands got to the original thread here: http://xdaforums.com/showthread.php?t=3108260

Ok now the tricky part: Plug your phone in and make sure you have ADB access.

Open a command prompt in the platform tools folder by holding shift, ctrl and right clicking.

Once you have access you will need to flash the 4.2.2 aboot with these scripts;

adb shell

su

dd if=/sdcard/aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot

exit

exit

Type these commands to install loki support and twrp

adb push loki_flash /data/local/tmp/loki_flash

adb push twrp.lok /data/local/tmp/twrp.lok

adb shell

su

cd /data/local/tmp

chmod 777 loki_flash

./loki_flash recovery /data/local/tmp/twrp.lok

exit

exit

adb reboot recovery

Once in recovery you will need to flash CWM recovery that you placed on your tablet. Once the install is done DONT REBOOT.

Go back in TWRP until you can reboot into recovery.

Reboot into CWM recovery DO NOT WIPE ANYTHING

Once in CWM recovery flash the 35A rom you put in your tablets storage. It will look like it failed don't worry. DONT REBOOT

Go back and find the SuperSU zip you placed on your phone and flash it. It will look like it failed don't worry.

Back up in CWM until you can reboot system. Click reboot system, It will ask to fix root, click yes and reboot into system.

It will spend some time upgrading android but will reboot into a rooted stock 35A rom. Again use the root checker app on your phone to make sure.

If you need to get back into CWM or TWRP if you flash it you will need to reflash the 4.2.2 aboot, once in recovery and after you do what you need you will have to flash the 35A aboot last to be able to boot back into the rom.

Hopefully I wrote everything right and you did it all right to profit. I have tried this way numerous times and it has worked perfect.

Again thanks to [MENTION=2560614]roirraW "edor" ehT[/MENTION]and [MENTION=5022682]Hnk1[/MENTION] for all there work leading up to this and all there help and patience with me.
