hello Audioniek ,
As you said , after cleaning the Archive directory and a fresh pull the new build ended with success .
Regarding the 3G modem support , here is the openAR repo , take a look in ( when you have time )
Unfortunately this team doesn't support the hs7x1x fortis model : it's a remake of duckbox tdt in wich they add this option . The most important to notify is the changes in the .config file specially "usb_networking_adapters" ; ppp directory and files (*modem*) added into cdk/root/etc/ also pppd application add into contrib_apps.mk file .
some years ago it was impossible for me to install E2 into flash in my box, thanks to you I have done; Now I want (and many other peaple) to have this option to enjoy it (my box) where I have only my usb key to have internet access
b Regards
