Great to see that you're modifying the builds of balbes150 to get additional drivers in.
Many X8-H Plus owners are desperate to get Wi-Fi working, and, contrary to the X8-H, the Plus has the AP 6335 Wi-Fi module.
Maybe you can also add the driver for the AP 6335?
The Broadcom drivers are outdated and don't work, but this page may help:
I'm especially referring to this part in the answer:
Good luck and thanks to you and balbes150 for all the great work and for not giving up!
can a Minix X8H-plus user try the wifi with this one :
I've added extra wifi firmwares.
I've tested this build on my X8-H and it haven't broken something : everything works as usual. (except 4K (but the X8-H has limited support/no support) and X265 (not supported by the X8-H))
Again : it's a tar file.
to update your box, the ARCH has to be S812.arm. if it's not the case, you have to use the .nocompat trick.
All credits to balbes150
wifi still not working new tar with wifi
