Is there any solution to this?

i had the CFW installed, but, updating youtube, i installed by error the latest ps3 firmware

after the install, was an error:





"the system software cant run correctly,
Install 4.83 or upper via usb"



Pd: i tried installing ferrox 4.83 from recovery menu, but it says "damaged data"

is there any solution to this, or the only one is installing the 4.83 official

thanks for read and sorry for the bad english
