1.Put 'exdata' folder on the root of your FAT32 USB Device and make sure USB Device is plugged in right-hand front USB Port (USB-000) Check this in multiMAN or FTP.
2. Install reACTPSN via package files/manager.
3. Create a new user profile on ps3 called 'aa' and login to it.
4. While exdata folder is present and usb device connected load 'reACTPSn' by pressing 'X'
(You no longer need to hold R1 for 9secs etc;this is now all automated )
5. Dependant on how many edats/raps in exdata folder this can take anywhere from 1-30mins ; eventually your ps3 will reboot
( for some reason on rogero 4.30cfw v2.03 after ps3 restarts I get corrupted data restore - skip restore by pressing 'o' and everything will be fine and more importantly
raps/edats are activated
