When installing a new ROM it says to perform a factory reset through CWM, which will remove all apps and data but should keep all your pictures, videos, songs etc.
It doesn't mention to wipe the System partition as well. Is this not necessary when flashing ROMs on a Nexus?
Prior to owning the N4 I had the Galaxy S 2 and it was always stated in the OP instructions to wipe data/factory reset, wipe system, clear cache, clear dalvik and then flash ROM and Gapps.
However, I don't notice in any guides or instructions for N4 ROMS to wipe the system partition, just the data partition. Is there a reason for this or is it not necessary to wipe the system partition? Thanks. Great guide by the way.
