Figured I would report back while I thank the community for all the work on these!
I got a cheapo rk3318 / X88 Pro 10 running Android 11 off Amazon Canada (https://www.amazon.ca/dp/B08NDGG95P)
Stupid me I didn't test an image on SD before flashing to emmc so, would not boot, bricked it pretty quickly - shuffled around micro soldering to short the clock pins, booted back into multitool and scrambled for hours before I realized you need to REMOVE THE SHORT right after booting if you want to access the emmc and erase / reflash it.
After a few more hours of tinkering I figure only the 5.15.35 images are working on this (Armbian_22.05.0-trunk_Rk3318-box_bullseye_current_5.15.35_minimal)
for some reason everything else I have tried is not working.
This version of the board doesn't seem to have appeared around here yet, it's X88-Pro-B-RK3318-D4-V1.6
In any case, I'm up and running that image, flashed to EMMC - going to have this thing run some 3d Printers with Klipper
