Try opening Kosmos Toolbox which was likely installed with your CFW. Select "Hekate autoboot profile" and set it to disable autoboot. This will allow you to go back into the default RCM mode upon reboot. You can also do this by going into your SD card files root\bootloaderhekate_ipl.ini. Open with a text editor and change the value of autoboot=1 to autoboot=0.
Hope this helps.
