Your PS3 is Downgradable for sure passed on the Info you put here.
check your PS3 with minimum Checker Version and see if it is 3.5 then you can downgrade to 3.55 if your ps3 min version is 3.56 you can downgrade using E3 4.3 CFW than go to Regoro CFW 4.3 V2.03 ( since your OFW now is less than 4.31)

thankx to all

can somebody suggests some other way
plz

there is no other way
NAND/NOR-Flasher or via CFW

doesnt matter u can downgrade if your model number is between 1000x to 2000x
all though now 3000x models are downgradable
there is a device called e3 downgrader it can help you downgrade ur model
not sure about 3000x models
