4.83 update error, help pls

Hello, I recently update a PS3 CFW 4.82, via Internet (principal menu) to 4.83, when the update was installing, the installation failure, and, the system reboot, but on recovery mode, and wants than I put a USB with a update, 4.83 or newer.

I tried with OFW, and CFW 4.83, CFW 4.82, and the system doesn't detect a valid firmware.
What can I do? Can I not loose the CFW?
Help guys, really, I don't want a paperweight
