Stora MS2110 kwboot (1 reply)

Hi Guys.

So it happened! I bricked my Stora last night, when tried to flash new U-boot.
It's completely dead, fan is spinning as soon as I connect power and no serial output at all.
I'm trying to use kwboot, but can't get past

root@debian:/home/user/Desktop/kwboot-tool# ./kwboot -t /dev/ttyUSB0 -b uboot.2017.07-tld-1.netgear_ms2110.mtd0.kwb -p
Sending boot message. Please reboot the target...-

I'm running the command and then connecting power to Stora, is there anything I'm doing wrong?
Or is there another way of bringing it back to life?
Thank you
