Never attempt to upgrade with a generic “1-255” string – it will fail.
While the benefits of upgrading are clear, the process is not without peril. The journey from a legacy version to the latest release is rarely a straight line. A common pitfall in the UBNT ecosystem is the inability to "skip" major firmware versions. A device running a very old version (e.g., Version 3) may not support a direct upgrade to the latest version (e.g., Version 6). This necessitates a "stepping stone" approach, where intermediate firmware must be downloaded and installed to prepare the bootloader and partition structure for modern code. Failure to adhere to these stepping stone requirements is a frequent cause of device bricking.
The primary driver for upgrading firmware across the "Version 1-255" spectrum is security. Ubiquiti devices, particularly those exposed to the Wide Area Network (WAN), are prime targets for malicious actors. Historically, vulnerabilities in older firmware versions have led to widespread compromises, such as the infamous 2021 breach involving Ubiquiti accounts. Firmware updates often contain critical patches that seal security loopholes, preventing unauthorized access and data exfiltration. Running a device on Version 1—the factory default or a legacy release—leaves the network susceptible to known exploits that have long since been mitigated in later versions.
