Goo manager is an app from the play store similar to ROM manager (but without the same risk). It links to goo.im (that's a website), which is a hosting site for android devs. With it, and a recovery that supports open recovery scripts (twrp or cannibal open touch are such for the optimus s), you can use it to download and install ROMs or any zips. For example you could use it to download the ROM and the format all zip for my ROM then flash both all from within the goo manager app. Also it will automatically notify you when a new update is ready to install. VERY handy tool indeed
