tremendouz : beside of your post being complete offtopic, your signature is VERY disturbing !
jerpelea : to fix wpa_supplicant I changed all "tiwlan0" to "wlan0" in wifi6.1 sources, and copied wifi part of Legend config to Hero, that did the trick.
hciattach : i'm using 2.1 from sony currently, it works.
The problem is the same - in 2.2/2.3 hciattach does not recognize device name of X8, otherwise it would work.
dhcpd is a bit different in original X8 as well, I use original to have resolving, otherwise it connects, gets ip, but no resolve (fails to set dns)
