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
