Already CFW, switching FW back and forth?
Also, i have a phat psp that i put to 1.50 w/ pandora. Can i backup the flash0 and NAND for each CFW i upgrade to and just copy that over to go back and forth from FWs that i have had (hope that wasnt too confusing) or will that just brick going from nand 3.52 m33 back to 1.50 (for example)
Slim 3.71->semi-brick->Nand Recovery->DCv3->3.71->3.80 m33-2->3.90 m33-3->4.01 m33-2
Want cintro for 4.01 m33? get cintro_390and Autostart_V4.zip, just follow the readme.
