i dont know if anyone has heard of this but flash gordon is used to install zips without cwm recovery. only thing is you cant install roms with this which makes sense since the os is running. you can flash a kernel, a mod, gapps, a modem, a RIL etc. but kernel shouldnt be touched without the phone being unlocked. and it will interpret the updater-script of this package and install its content just like a recovery would. i can see this being used for just only tweaks for the systen due to a proper recovery not being on here. we can use this for other tweaks for these phones until a recovery can be found
