Thanks to:

[MENTION=2385005]invisiblek[/MENTION] for building and permission to link to his CM13 builds folder, and all his work to get this to the point it is right now, including getting Mobile Data to work

[MENTION=5022682]Hnk1[/MENTION] for making me aware that the builds had started

Don't expect support from anyone in this thread. Help might come but it's likely that if you're experiencing a problem that [MENTION=2385005]invisiblek[/MENTION] is already aware of it, or it's a CyanogenMod issue that all ROMs will have. In the meantime, please feel free to communicate with other CM13 for VK810 users here to confirm/deny the existence of any issues you might have, or discuss any workarounds when possible.

Please mention what build date of CM13 you're on when you're discussing issues.

Installation Notes:

It's smooth as butter.

Flashing this definitely doesn't work with a newer bootloader. I recommend flashing this from TWRP v2.8.7.0 after a fresh flash of the 11A KDZ and downgrading the bootloader in order to install the initial Loki'd version of TWRP v2.7.0.1 and then upgrading to 2.8.7.0, or if necessary, first the 22B TOT and then the 11A KDZ after. All necessary instructions are in my [VK810.4G] [altev] most reliable way to root and install a custom recovery thread. I actually manually downgraded the aboot (bootloader) even though I was on 11A and my instructions at that link specify that downgrading the bootloader further wasn't necessary, so I haven't tested straight from 11A's bootloader.

When I had tried [MENTION=2385005]invisiblek[/MENTION]'s TWRP v3.0 July 19, 2016 build for the VK810 (the current build that's available), it accessed internal storage just fine - my MicroSD card is formatted ExFAT so that might be the trouble - I haven't tested USB OTG on this build, nor backing up or restoring. This build of TWRP flashed the ROM okay, and looked like it flashed OpenGApps Pico okay, but no matter how many times I tried or even trying to flash OpenGApps Nano, when the ROM was booted the Play Store still wasn't there. Reverted to a known good version of 2.8.7.0, wiped all and fresh flashed ROM and OpenGApps Pico and all's good so far.

I use Slim Zero GApps for Marshmallow (6.x) with this, available at [GAPPS][6.0/5.1/5.0][arm/arm64] Official Slim GApps. [MENTION=2385005]invisiblek[/MENTION] uses Open GApps (Pico Package). This tablet uses an ARM processor and CM13 is Android 6.0x.

OTA's work and point to [MENTION=2385005]invisiblek[/MENTION] 's newer builds when they're available. If you take OTAs and you had system Xposed installed, you'll have to flash Xposed again.

[*]Root can be enabled without SuperSU by first enabling the "Developer options' in Settings. Do so by going to Settings / About tablet / scroll down and touch "Build number" about 10 times in a row, then you can see "Developer options" in the main Settings menu immediately before the About menu. At the bottom of the first screen of the "Developer options", under "Root access", enable either "Apps only" or "Apps and ADB", for most users' purpose. I believe "Android debugging" (two options down further from the "Root access" in "Developer options") was already enabled.

System Xposed build 86 (sdk23) for Arm processor, and Greenify including the latter's Xposed module appears to work okay. Trying G3TweaksBox (made for stock but might still provide some functionality under CyanogenMod) rotation tweaks doesn't appear to help the rotation issue I'm having. G3TweaksBox's Sound options like "Link Ringtone and Notifications volume", "Force media volume control" and "Auto expand volume panel" all appear to work. Other modules I've tested: Amplify, Battery Home Icon (% text at least for 100% is offset), DirectAPKInstall Module doesn't work (I think it didn't work on stock on this device, it works fine on my VS985 G3), Flat Style Bar Indicators, Marshmallow SD fix, Play Store Changelog, installed but haven't tested YouTube AdAway and YouTube Background Playback. I had attempted Systemless Xposed and it wouldn't flash from TWRP, but it's supposed to specifically require SuperSU v2.76, so I didn't necessarily expect it to work with CM's built-in root. Haven't tried SuperSU yet, but if you do, disable CM's built-in root first.

Do not ask about when anything will be fixed, nor requests for features/new builds etc, or when CM14 (Nougat) or CM26 (Zagnut) will be released.

What's broke (at least on cm-13.0-20160716-UNOFFICIAL-vk810.zip):

Camera

Brightness adjustment (I recommend Lux Auto Brightness or Lux lite by Vito Cassisi and it can be chosen to integrate with CF.Lumen by [MENTION=631273]Chainfire[/MENTION])

Occasional black screen when you try to wake up the tablet. It's necessary to hold the power button in for 10 seconds or so to force turn it on, then either continue to hold the power button or let go and press again to turn boot the tablet back up. [MENTION=2385005]invisiblek[/MENTION] hasn't had this issue on his own VK810 in a while so I need to provide some further testing and reporting once I experience the issue again. I haven't yet tried the GApps that [MENTION=2385005]invisiblek[/MENTION] uses just to rule that out although I doubt if that'll make a difference.

Rotation might not work - I haven't tested on the fully "stock" ROM and have a bunch of apps/tweaks installed now so will have to double-check on a fresh flash later. The best app workaround I've found is Rotation Control. This enables you to manually control rotation via icons in the pull down notifications. There's other apps to do the same thing but one of the other highly rated ones didn't work for Reverse Portrait, and the other one didn't have Reverse Portrait at all. At this time I have no idea if the tweaks I made in G3TweaksBox might've improved the "Rotation Control" app's behavior, or if any other settings I have going on might've one of the other apps I tested.
