Firmware downgrade over serial.

Good day everyone - I'm new here.
I recently acquire a second hand KT2 - and since it came with firmware 5.11.1.1 I realized after enough reading that it wasn't possible to do a JB over software. I have now soldered terminals to the serial port.

I was wondering if it is possible to just extract the rootfs.img from the factory update and rewrite the mmcblk1 partition with the content of this image using dd over the serial connection?

I can see that on the update images sometimes there is a uImage, which I believe to be the kernel, but I'm not sure if the kernel and the rootfs.img must match.
