I'm having trouble installing firmware on a NanoStation loco M5 (XM). What should I try next?
I followed the First Install directions. After putting the NanoStation into TFTP mode, it responds to ping. TFTP transfer appears to be progressing: the LAN1 LED flickers rapidly, and the tftp2 progress bar moves steadily. But the transfer ultimately fails. The NanoStation LAN1 LED flickers for a few more seconds, and then the flashing 1-3, 2-4, 1-3, 2-4 pattern resumes. After 3 retries, tftp2 says "Unable to get responses from the server."
I can successfully install Ubiquiti airOS using the same procedure, except of course with the file XM.v6.3.5.33321.210716.1345.bin from Ubiquiti.
The airOS main status page shows Version: v6.3.5 (XM). The date code on the sticker is 1340K. I ran the TFTP clients on Windows 10. I tried both Windows' tftp command line and tftp2. I tried the AREDN firmware files aredn-3.21.4.0-ar71xx-ubnt-bullet-m-factory.bin and aredn-3.21.4.0-ar71xx-ubnt-loco-m-xw-factory.bin.
after putting into TFTP mode, can you ping 192.168.1.20 successfully? if not, you need to resolve that issue first.
Yes, the NanoStation responds to ping 192.168.1.20 after I put it into TFTP mode.
This worked for me: Use tftp to install XM.v5.6.15-cpu400.30572.170328.1107.bin from Ubiquiti. Then log in to airOS and click System > Upload to install aredn-3.21.4.0-ar71xx-ubnt-bullet-m-factory.bin. It asks to consent to install third-party firmware. Then it installs it.
This procedure doesn't work with recent versions of airOS, nor with XM.v5.6.15-sign-cpu400.31612.170908.1458.bin (note that name contains "-sign"). Attempting to upload AREDN firmware elicits an error message saying it refuses to install untrusted software.
