You aren't able to just flash a new kernel image?
Or you have flashed your image and now the device fails to boot?
Case 1:
- from your linux pc: type "flasher-3.0 -f -b -k zImage", connect your device to the usb cable, reboot your device.
- or in your device: "fiasco-flasher -f -k zImage", reboot your device
Case 2: get another kernel image, for example download the kernel deb from the repository and unpack it, or unpack the FIASCO firmware image, and then go to "Case 1"
