macOS TFTP router recovery
Prepare the Mac, firmware file, IP settings, and TFTP server before retrying an ImmortalWrt router recovery.
ImmortalWrt recovery is the process of restoring a router that cannot boot normally after a failed flash or configuration problem. In many cases the recovery path is inherited from the router bootloader and is similar to OpenWrt-style recovery.
ImmortalWrt is an OpenWrt fork, so many concepts are familiar: device targets, firmware images, LuCI, failsafe, and recovery workflows. Still, always match the exact ImmortalWrt build to your device.
A frequent pair is router 192.168.1.1 and Mac 192.168.1.254. Other routers ask for 192.168.0.66, 192.168.0.100, or vendor-specific values.
Place the firmware in the TFTP root folder, start the server, then power the router into recovery mode while connected by Ethernet. Watch for the router request rather than repeatedly changing files blindly.
Use the file name and image type requested by your device. Some bootloaders require a specific filename; others request any matching file from the TFTP root.
If recovery does not start, recheck static IP, Ethernet port, firewall, firmware filename, and whether the router actually entered recovery mode.
Often the concepts are similar, but the device model and bootloader decide the exact recovery steps.
No. Use the exact build and image type for your router model and hardware revision.
It helps run the TFTP server and organize the recovery environment on macOS.
