Am trying to flash Ubiquiti NanoBeam AC with AREDN firmware. Changed existing firmware to 8.7.0 and copy AREDN firmware to node and wrote the program to bypass checking process,but when I try to load the firmware from the Ubiquiti WA prompt, I get a group of error messages starting with error in line 1 and error in line 17. Had also tried logging out of Ubiquiti prompt and upgrading firmware direct from setup in node but upgrade fails due to not being signed.
