    sudo ./sercomm-recovery enp0s3 recovery_turboplus_stock.bin
    this file is for Turbo+ only, it isn't suitable for Turbo without plus, with 256 MB NAND

  • For GIGA:
    sudo ./sercomm-recovery enp0s3 recovery_giga_stock.bin
    where the enp0s3 network interface connected the router.
    ifconfig - list on available network interfaces
