Ok, so I downloaded and installed Fake 4.0 from Cydia and it asked to reboot after installation. After it was all done, my iPhone just stays on the apple boot logo and stays there for 3-5 mins and then shuts off to only turn back on to the apple boot logo again. I have it plugged into iTunes and I can hear the chime when it charges but see no functionality. I put it back in DFU mode and it seems like the option is to restore. Should I restore or is there another solution? Please help cause I have important files that has not yet been backup yet!!
