Every legitimate psp2updat.pup file contains a SHA-256 hash of its contents. The Vita’s boot ROM checks this hash against a physical key fused into the console’s hardware. If the hash doesn’t match—or if the file has been modified by even a single bit—the Vita will reject the update and throw an error (usually C3-12077-7 or similar).
