Desire to restore factory firmware for resale or reliability.
Step-by-step review of the update process
Finding the update: HP’s support site is slow, search is broken, and the F870g may be listed under a different region/model variant.
Installation: Via USB is more reliable than Wi-Fi. The on-printer screen prompts are confusing (tiny text, non-intuitive menus).
Post-update: Printer restarts twice. If successful, you’ll see no visible changes – unless you had third-party ink, in which case you’ll see an “Incompatible Cartridge” error.
If the update fails / recovery
If interrupted, try re-running the official updater.
Some vendors provide a “recovery” or “low‑level flush” tool—use only the official method.
If the device is unrecognized, try different USB ports, cables, and another PC.
Contact vendor support with device model, serial number, firmware file used, and error messages.
If irreparably bricked, professional data recovery or RMA may be necessary.
