Many routers include a hidden TFTP Recovery Mode inside their bootloader, allowing a corrupted or soft-bricked firmware to be restored without opening the device or using a USB-to-TTL adapter.
This repository demonstrates the complete recovery process using the TP-Link TL-WR840N v6.20 as the example router because it is one of the most widely used home routers in many countries.
Although the included firmware files are specifically prepared for the TL-WR840N v6.20, the overall recovery process is nearly identical for many TP-Link routers and several other router brands that support TFTP recovery.
Simply replace the firmware with the correct one for your router model and follow the same steps.
⚠️ Always use firmware that exactly matches your router's hardware version.

- Keep holding RESET until Tftpd64 finishes transferring the firmware.
- Release RESET.
- Wait for the router to reboot.
Your router should boot normally after flashing.
The TP-Link TL-WR840N v6.20 is used only as an example because of its popularity, making it easier for most users to follow along.
If you're recovering a different router:
- Delete the existing .bin file.
- Download the correct firmware for your router and hardware version.
- Copy your router's firmware into the folder.
- Rename the firmware to:
original.bin
- Run this command in the same directory:
dd if=original.bin of=tp_recovery.bin bs=512 skip=1The generated
tp_recovery.bin
is the file Tftpd64 should serve.
- Start the TFTP server and follow the same recovery process.
Note: Some routers require a different TFTP filename, server IP address, or recovery procedure. Check your router's documentation or bootloader requirements before flashing.
Never disconnect power while flashing.
Doing so may permanently brick the router.
