Firmware download link is fixed, thank you

If you want to recovery bootloader, either:
- Flash the whole image again:
sudo upgrade_tool uf /path/to/update.img

- Update the bootloader
sudo upgrade_tool DB /path/to/loader.bin # this download the loader to the board
sudo upgrade_tool UL /path/to/loader.bin # this shall upgrade to loader of the board
