In going from 1f5 to 1f0 you may have probably downgraded your BIOS since you say that your phenom works fine but FX does not. If you still have the update version 1f5, then put your 1100t into the mobo, update BIOS to 1f5 using the pen drive and then install the FX 8350. This is one possible way of trouble shooting.
Do apply thermal paste properly each time you swap the cpu's
