Yes, openwrt-atheros-ubnt5-squashfs.bin already contains the kernel and the rootfs.
OK, I reflashed my Loco 5 with XS5.ar2313.v3.4.4390.090521.1803.bin from UBIQUITI
After, I tried to flash from web admin AirOS with your firmware
http://nightwing.lugro-mesh.org.ar/download/0.6/nightwing_v0.6beta4-ubnt5-squashfs.binand AirOS give this message "Bad firmware image"
What are you suggest now ?
