Mediatek MT8176 & MT8173 Development

Mediatek MT8176 & MT8173

MT8176 is a Hexa-core, 64-bit tablet platform with ARM Cortex-A72/A53 with clock speeds up to 2.1GHz and IMG PowerVR GX6250 GPU at 600MHz,

• CPU Cluster 1: ARM Cortex-A72 @ 2.1GHz
• CPU Cluster 2: ARM Cortex-A53 @ 1.7GHz
• IMG PowerVR GX6250

Development

Mediatek devices are known for little to no Custom-ROM development. That's why I'm collecting stuff for building a ROM for my MT8176 device - a Xiaomi Mi Pad 3. Somebody uploaded a full source-code for building AOSP 7.0 for GPD XD+, a device also based on Mt8176 SoC. I trimmed the source-code down and re-uploaded the important stuff on my github.

How to build recovery for Peloton Tablet?

I know this repo has been inactive for ~2 years, but... I'm trying to get root or any custom recovery working on a Peloton 21" RB1VQ Tablet which is an MT8173 chipset armv8l

Here's some more device info from ProjectConfig.mk and build.prop file at https://gist.github.com/sagz/64dbe6611e23da7084fe7b0b6f2da1a7 (There's also fastboot getvar all output there in the comment of the gist)
Also, they seem to have posted their kernel here: https://github.com/pelotoncycle/opensource-ruby/

Bootloader is unlocked and I tried a bunch of things and learnt that it doesn't have a recovery partitition and uses a recovery-in-place logic. I also tried mtk-su from https://www.xda-developers.com/mediatek-su-rootkit-exploit/ but this tablet is patched with August 5, 2019 Android Security Patch.

Any tips on how I can try a 'generic' recovery image since bootloader is unlocked? maybe the getvar dump in the gist might help you assess?
