I followed the tutorial to Install Rebug PS3 CFW 4.21.1 but I can't entry in recovery mode, the second time that I press the power button the PS3 turn off again without do the beeps. How can I resolve?

I have got a flasher, and I'm currently on OFW 4.30 on a 3.56 min. version cech-25xx. I know it's possible to flash to Rogero 4.30, but is there some way to use the half dual boot option of it on a PS3 with a 3.56 FW base?

If not, could someone please advise me on any other means to switch back and forth between CFW and OFW, or any other ways to still use the PSN?
