My question is -- Can I just flash the system.img using mfastboot or do I have to use the house of moto method? I am not a complete idiot but I get confused with some of the house of moto's steps. Sorry to be a bother
You can use RSD Lite (which will erase everything and leave you 100% factory stock), or the house of Moto Methods.
You can NOT flash just system.img. You need the boot.img, as well.
Might be able to fastboot flash JUST system and boot....if it were me, I'd RSD Lite back to full stock.
