Well, I'm no expert on the 48SX, but since no one else has chimed in, I'll give my 2 cents.
Basically, as far as I know, the rom in the 48 series was "hard-coded" (for want of a better term) at the factory. It is not re-writeable. If the rom has become corrupted on your 48SX, it cannot simply be re-programmed.

That's perfectly true, the ROM in the 48S/SX/G/GX/G+ is really ROM, non-writeable. If it's gone or defect, the ROM chip, a contact, the PCB or the CPU has to be defect.
What symptoms does your 48SX exhibit?
