Just tested the final release on a MECOOL KII Pro (S905D) . Everything I tested worked well. Even DVB-S2 with tvheadend.
Notes:
- Download the generic .img.gz, do not chose your device at dtb, it will take you to 9.2.6
- Get the dtb.img from the post linked below, do not use the included one, it will result in a black screen
- For DVB to work install the crazycat drivers from the “services” addons (did not try media build)
