A guided TFTP Server recovery tool for macOS
Before another retry, confirm that the router has really entered its recovery state and is ready to ask for firmware. This saves time and avoids guessing.
TFTP: a simple local file-transfer method. In recovery, the router may ask your Mac for one firmware file.
Recovery mode: a temporary rescue state used when the router cannot start normally. It usually exposes only the basics needed to accept firmware.
Bootloader: the small startup program that runs before the normal router system. Many recovery flows are controlled by it.
Static IP / same subnet: a temporary Mac address such as 192.168.1.254 so the Mac can talk to a router waiting in recovery mode.
What to do: check the router label and hardware revision, then download matching recovery firmware. Why: mismatched firmware is a common cause of failed recovery. You should see: a filename, model, and hardware revision that clearly match.
What to do: temporarily set the Mac Ethernet IP to the address required by the guide, such as 192.168.1.254. Why: this lets the Mac communicate with the router while it is in recovery mode. You should see: Ethernet connected, with the Mac IP and router recovery IP in the same local network range.
What to do: select the firmware file and let Router Recovery wait for the router request. Why: the router recovery window may be brief, so the Mac should be ready first. You should see: the app waiting for the router request or showing that a request was detected.
What to do: follow the model guide, usually power off, hold Reset or WPS, then power on. Why: the router must enter recovery mode before it can request or accept firmware. You should see: the documented LED pattern, a brief network response, or the app detecting a firmware request.
Recovery mode is a minimal boot state used to accept firmware or expose a rescue interface. It may not run DHCP, Wi-Fi, or the normal admin page.
A common pattern is power off, hold Reset or WPS, connect power, then release when the LED pattern changes. Always follow the model-specific guide when available.
Look for the documented LED pattern, a brief ping response, or a TFTP request. If none appear, the button timing or Ethernet port may be wrong.
Some bootloaders only wait a few seconds. Your Mac static IP, firmware file, and TFTP server should be ready before powering on the router.
Retry with the correct port, button, firmware filename, and IP pair. If the device never responds, it may need serial TTL recovery or a vendor-specific tool.
Not always. OpenWrt failsafe and bootloader recovery are related rescue concepts, but the steps and network behavior can differ.
Some bootloaders expose networking only during a short recovery window after power-on.
Check the button sequence, Ethernet port, power timing, and model guide. Some cases require serial TTL access.
