@Nick A Hi, thank you for the quick response!
So far the attempts to boot the transpeed image would hang during boot most of the time, but I did manage to get a working shell once, albeit still without any networking.
The WiFi chip is BCM4334, the physical print on the chip wasn't too helpful, but in either case it's the exact same model as shown on the pictures on this article https://linux-sunxi.org/T95 (4/32 version).
I can't currently test HDMI but it is attempting to load Plymouth despite the config specifying otherwise.
I attached a boot log of the stock Android image, if it helps at all.
Thank you so much for helping out, I really appreciate it!
