Here's what you should know:
Official Source Required – Ubiquiti firmware is only legally and safely available from their official website: ui.com/download. Avoid third-party "free download" sites—they often bundle malware or corrupted files.
Version 1.255 Context – This version number looks like it might be for older airOS devices (e.g., NanoStation, Rocket M). The latest stable versions for those legacy products are typically hosted on Ubiquiti's legacy download portal.
How to get it legitimately for free (yes, it's always free from Ubiquiti):
Warning – If you found a link claiming "Version 1.255 FREE Download" with a file host like Mediafire or Dropbox, do not use it. Unofficial firmware can brick your device.
If you tell me your exact Ubiquiti model (e.g., NanoStation M2, Rocket M5, LiteBeam), I can point you to the correct official download page for version 1.255 or a recommended stable alternative.
