Couldn't find that crappy build.prop anyway... but I adb pulled it (after having flashed the system.img) just to make a diff with my previously modified one (that I backuped).
Well, running 4.4.2 fine now, with no app to re-install, kinda "OTA" like... with the added mess up, but kept my root so... :)
