• Set server ip (in our case it is 192.168.2.254) on your network interface to which Jalapeno is connected.

• Copy u-boot firmware to tftp server directory and rename it to fwupdate.bin:

sudo cp lede-ipq806x-Jalapeno-squashfs-nand-factory.ubi /var/lib/tftpboot/fwupdate.bin

• Run u-boot upgrade command:

(IPQ40xx) # run do_recovery
