PS3 Need Help! - Stuck on Petitboot without keyboard, recovery menu not working

[nicklamn]

When I boot recovery mode it just boots Petitboot. I wanted to ensure petitboot worked, and that I could use it, and I don't currently have a keyboard. I have a phat ps3 NAND model. Is there anyway I can boot GameOS instead of OtherOS? (CFW 4.81 Rebug Rex) Or atleast boot recovery instead of other os? Holding powerbutton until the 2 beep combo just boots petitboot.
