I download it and try to install but i get bootloop with this firmware..
Edit: Sorry my bad, now i see is sysupgrade file and not tftp recovery, i try to install it as a tftp recovery file and thats why i get bootloop. I go to install it now and try again!
Edit 2: I notice that the official openwrt is a little bit different than the other i flashed and try. At official openwrt i can modify the default 192.168.1.1 and change it at the same form. To the other version "unofficial" i install i had to add new address and cant modify the default.
Even modify and change to 192.168.15.1 and fail and try with 192.168.15.1/24 with or without mask black at the official openwrt i cant change successfully the ip address and get the same error, changes fail bla bla..
