Android DTB itself is broken in many ways, mainly because wifi gpios from DTB do not show up in the gpioinfo output. It is more important to put the brcm4335-sdio firmware in /lib/firmware/brcm, which is missing in the armbian repository. iw phy0 info shows support of the 5GHz channels, but i don't have such access points nearby. I will check tomorrow with my dual-band AP.

It happened a few days ago that I rebuilt my complete firmware package to try something with another device. An HC4 firmware binary also automatically falls out in this process. If you like, you can put it on a microSD card (dd bs=512 seek=1 conv=notrunc,fsync if=u-boot-meson.bin of=/dev/${entire-device-to-be-used}), place the prepared microSD card in your HC4 and start it with the boot button pressed. Check whether it meets your expectations, and if all tests are successful, you can transfer it to the SPI flash.

The longer answer is that for standard releases, updates only occur with each release cycle (i.e. every three months in Feb, May, Aug, and Nov each year. So you will get new kernel release on that schedule. Armbian also has rolling release repositories and these put out new versions on a frequent basis. And you should be able to switch between stable releases and rolling release apt repositories using armbian-config. Note that rolling releases don't get any testing (other than automated builds) and therefore may not be suitable for many users needs. But those are your two options.

We're in the middle of the May release, so new packages should eventually hit repo in a few days/weeks.
