In the settings, set the to the folder where you placed the Version 1255 file.
Next comes tftp —Trivial File Transfer Protocol. The word “trivial” is a masterclass in engineering understatement. Unlike its more sophisticated cousin FTP, TFTP uses UDP and offers no authentication, no directory listing, no security. It is bare-knuckle data transfer, designed for the leanest of environments. Its very triviality is its virtue: it works when nothing else will, often during the most vulnerable moments of a device’s life—a bootloader stage, a recovery mode, a factory state. By invoking TFTP, the operator acknowledges that elegance must sometimes yield to raw utility.
Temporarily disable your computer's local firewall, or create an inbound rule to allow traffic on . Firewalls are the number one cause of failed TFTP transfers. Step 3: Connect to the Device and Initiate the Install
Once the device has reloaded, confirm that the upgrade was successful:
During the upgrade process, you may encounter issues such as: i tftp upgrade firmware version 1255 download install
Temporarily disable Windows Defender Firewall or third-party security software on the host machine. Firewalls frequently block incoming and outgoing UDP port 69, which TFTP requires. 2. Choosing and Setting Up a TFTP Server

Once the file transfer hits 100%, the device will begin writing version 1255 to its flash memory. This process usually takes 3 to 5 minutes.
