Firmware update and recovery errors occur on HP LaserJet and HP All-in-One printers when a firmware upgrade fails or becomes corrupted.
In severe cases, the printer may become “bricked”—unable to boot, stuck on the HP logo, or completely unresponsive.
This Knowledge Base article explains why HP firmware failures happen, how to recover printers safely, and when hardware replacement becomes unavoidable.
These errors indicate failure in the printer’s firmware storage or execution process, preventing normal startup.
Stuck on HP logo / Initializing
Blank or frozen control panel
Continuous reboot loop
Printer not detected on network or USB
Firmware Error
Update Failed
Printer powers ON but never becomes Ready
Firmware errors affect all printer functions.
Printer firmware is stored in non-volatile memory (flash/ROM) on the formatter board and controls:
Boot sequence
UI (control panel)
Network stack
Print engine logic
Security & authentication
Firmware failures occur when:
Power is interrupted during update
Wrong firmware model is installed
Firmware file is corrupted
Storage memory degrades
Secure boot validation fails
Incompatible downgrade attempt is made
To protect the device, the printer may enter bootloader or recovery mode.
Power cut during firmware update
Automatic firmware update overnight
Updating via unstable network
Installing firmware meant for another model
Downgrading blocked firmware versions
Using unsupported USB devices
Power OFF printer
Unplug power cable
Wait 20 minutes
Plug directly into wall socket
Power ON printer
✔ Clears temporary firmware initialization locks
If printer partially boots:
Access Embedded Web Server (EWS)
Reinstall latest correct firmware
Do not interrupt power
Used when UI and network are inaccessible.
Procedure (generalized):
Download correct firmware for exact model
Extract firmware file (usually .bdl / .rfu)
Copy to FAT32-formatted USB drive
Insert USB into printer
Power ON printer
Follow on-screen or automatic recovery process
Many HP printers auto-detect firmware on USB during boot.
(Model-dependent)
Power ON while holding:
Cancel + Back
OK / Resume
Home + Power
Printer enters Firmware Recovery Mode
Load firmware via USB
⚠ Button combinations vary by model.
Disconnect:
Network cable
USB cables
DIMMs
USB accessories
Retry firmware recovery with bare minimum hardware
If printer:
Does not detect USB
Does not enter recovery mode
Remains dead after correct firmware
➡ Formatter board firmware storage is damaged
➡ Replace formatter board
| Symptom | Root Cause | Fix |
|---|---|---|
| Stuck on HP logo | Corrupt firmware | USB recovery |
| Reboot loop | Failed update | Firmware reinstall |
| Blank screen | Bootloader failure | Formatter replacement |
| Network unreachable | Firmware crash | USB recovery |
| Error after downgrade | Version blocked | Install latest firmware |
Firmware enforces secure boot & supply authentication
Downgrades may be intentionally blocked
Avoid unofficial firmware sources
Restrict firmware update access
Disable auto-updates if using compatible cartridges
Always update firmware using stable power
Use wired network or USB for updates
Confirm exact printer model before update
Avoid firmware updates during business hours
Keep firmware packages archived
HP firmware update and recovery errors are among the most critical printer failures.
Most bricked printers can be recovered using USB firmware recovery or bootloader mode, but formatter replacement is required when firmware storage is damaged.
Careful update planning and power stability are essential to prevent firmware corruption.
