Bellissimo !

It would be nice to TAR all these files in an archive in order to unpack them easily on a router.
add the list of all files in list.txt, and then :
tar -cvf DumaOSfiles.tar -T list.txtEDIT:
ClintB from the AU Forum sent me the TAR file :
https://www.upload.ee/files/12126113/DumaOSfiles.tar.htmlAt this point i guess only unpacking the files will not be enough...
EDIT
well so good news, unpacking the files, sending the uci commands, doesn't brick or freeze the modem. i even rebooted and it is still working.
but unfortunatly, sendind the command
/etc/init.d/dumaos startdoesn't seem to work...i have to CTRL+C else it is stuck.
and when going to
http://192.168.1.253/desktop/ gives a nice 404 error not found

i think there are a few things to do to make it working but i don't know what

EDIT
OK, so i found that DumaOS is not working with nginx but
uhttpd, and it is set to work on port
81So it is necessary to start uhttpd first, and dumaOS after:
/etc/init.d/uhttpd start
/etc/init.d/dumaos start
and then go to
http://<your_router_ip>:81/
so now i'm really close

looks like uhttpd can't access to a json file. the 2 interfaces (uhttpd and nginx) are supposed to cohabit together, I wonder if a rule in nginx prevents uhttpd from retrieving some data. i know that Ansuel heavily modified the nginx settings, i guess the problem is here...
