• Warranty implications: Downgrading the firmware may void your printer's warranty, depending on the terms and conditions.
• Security vulnerabilities: Older firmware versions may contain known security vulnerabilities that could be exploited by malicious actors.
• Instability: Downgrading the firmware can potentially cause instability or bricking of the printer, especially if done incorrectly.

Identifying Your Current Firmware Version

• Bricking: An interrupted or incorrect downgrade can turn the printer into an expensive paperweight (non-recoverable without mainboard replacement).
• HP Signing Keys: Most newer firmware (2018+) is cryptographically signed. The printer will reject older, unsigned firmware.
• No Rollback Allowed: If HP has set a "minimum version" fuse on your printer's EEPROM, downgrading is impossible.
