I followed the instructions and updated it to kmeaw's CFW. I didn't watch the entire update process I was too scared to see it bricked. SO when I came back to my tv. I was back in the PS3 but I didn't see any app_home folder in the game section.
Can I redo installing it?
Yes you can 'redo' it. If it's not there means it didn't get installed.
Yea do the whole process and watch it this time seeing as the first time nothing happend and your ps3 did not brick.
magic, lots of it
