Changing PS3 CFW NoBD to a normal CFW version

hello, i want to use discs on the ps3, when i first installed cfw i had to remarry the disk drive since apps resulted in a black screen, and to be sure i installed the noBD CFW version. is there any possibility i can change the CFW? will it result in a soft brick? is there no way i could use the disc drive with this version?

any help is appreciated.
