Installing the initial (necessary) TWRP v2.7.0.1 and updating it to the latest TWRP v2.8.7.0:

The link is in the "DOWNLOAD" section below the "DISCLAIMER" towards the bottom of the first post.

Credit [MENTION=4557482]Drgravy[/MENTION] for the original instructions but I prefer to run the commands directly on the device instead of from a PC via USB Cable and ADB.

2. Download TWRP v2.8.7.0 from http://xdaforums.com/lg-g-pad-83/orig-development/recovery-twrp-2-8-7-0-t3150812

4. While you're in the Play Store, install "Terminal Emulator for Android" https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en

5. Launch X-plore.

6. Enable root mode in X-plore:

6A. Click the three-dot menu button in X-plore's upper right corner.

6B. Choose "Configuration".

6C. In the "Root access" section, click the gray area below it and choose "Superuser + mount writable".

6D. Give X-plore SuperUser permissions by choosing "Grant" in the SuperSU prompt that pops up. It might not open this prompt until a later step when you actually access root.​

7. Find the "VK810_twrp_2.7.0.1.zip" file you downloaded in step 1 above. It should be on your internal storage in the Download folder.

8. Click once on the zip file - this will show you the files contained in it.

9. Navigate to the other file manager pane by choosing "SWITCH PANE" in the upper right corner.

10. Choose "Internal storage".

11. Navigate to the original pane by choosing "SWITCH PANE" again.

12. Select all the files inside the zip.

13. Choose the "Copy" icon in the toolbar on the right or left side of the screen. Choose "OK" at the confirmation prompt.

14. Now navigate to root. Give X-plore SuperUser permissions by choosing "Grant" in the SuperSU prompt that pops up.

15. From root, navigate to data/local/tmp.

16. "SWITCH PANE" to where you extracted the files from the zip.

17. Select "loki_flash" and "twrp.lok".

18. Choose the "Copy" icon in the toolbar on the right or left side of the screen. Choose "OK" at the confirmation prompt.

19. Launch "Terminal Emulator" installed in step 4 above.

20. In Terminal Emulator type (make sure no typos, or can copy/paste to be sure):

su

cd /data/local/tmp

chmod 777 loki_flash

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

reboot recovery

Instead of "reboot recovery" you can use an app such as "Quick Reboot" from the Play Store at https://play.google.com/store/apps/details?id=phongit.quickreboot to reboot to recovery.

21. For getting to custom recovery with the tablet off, press and hold the Down Volume button. While continuing to hold the Down Volume button, press and hold the Power Button. The screen should come on in the stock-looking recovery and you can let go of both buttons). "Factory Reset" will no longer perform a Factory Reset. That's what you choose to get into custom recovery.

22. Update to to the latest TWRP v2.8.7.0 that you downloaded in step 2 above by (in TWRP v2.7.0.1) choosing "Install", navigating to where you downloaded the TWRP v2.8.7.0 zip (probably in internal storage in the Download folder), and choosing to flash the zip.

You can put a different custom recovery on the same way.

23. You can reboot into the newer TWRP by choosing the reboot recovery option.

Flash to the latest stock ROM so that you can have it with root:
