Ohh that's the other thing I needed answered hahah, I've read to toggle that on before doing it and couldn't really find out what it does + how to do it?
There is a small tutorial+download link here-
You must login or register to view this content.
Basically download the qa toggle .pkg file
Put it on your usb (not in a folder)
On your ps3 go to "install pkg file" and hit install the qatoggle.pkg
You will now see a qa toggle icon
When you are ready to install your new cfw click the qa toggle icon
You will hear it beep once then return to the menu (make sure it beeps)
Now you can install your new cfw!
