so I asume it worked and I am now in this build.
Yes, you're now using the test build that enables the Marvel wifi driver.
I did not try the bluetooth stuff as per Chewitt as the wifi is more important than the bluetooth for now
However you still need to install the firmware as directed by chewitt as the firmware file is also required by the WiFi driver before it can work.
Please install the firmware file, reboot, enable Wifi and Bluetooth, then post another dmesg.txt, confirming if Wifi and Bluetooth are now working.
