Here’s a step-by-step guide to downgrade the firmware on an HP OfficeJet Pro 6950 printer.

Method B – Using a .BDL file (Remote Firmware Update)

If you only have a .bdl file:

  1. Open your browser.
  2. Go to the printer’s IP address (find it via Network menu on printer).
  3. Log in as admin (default password is often the printer’s PIN or serial – check sticker).
  4. Navigate to Tools → Firmware Update → Select File.
  5. Choose the older .bdl file.
  6. Click Update.

Step 1: Identify Your Current Firmware Version

  1. On the printer’s touchscreen, tap Settings (gear icon).
  2. Go to Printer Maintenance > Update the Printer > Printer Update Preferences > View Printer Update History.
  3. Write down the current version. If it starts with LBP1CN20xx or higher, you are on a restricted version.

4.2. The Recovery Mode Method

If a downgrade is technically supported by the specific hardware revision, it typically requires forcing the printer into "Recovery Mode."

  1. The printer is disconnected from the network to prevent it from auto-updating during the process.
  2. The user initiates the update via a computer connected via USB.
  3. Specific older firmware installers (if available in the archives) are executed.
  4. The user must hold specific physical buttons (often the "Resume" or "Cancel" button combination) while powering on to bypass standard boot checks, forcing the printer to accept the USB firmware image.

5. Replace the Printer

If you are constantly fighting firmware battles, consider buying an eco-tank printer (Epson EcoTank or Canon MegaTank) that uses refillable ink bottles and has no cartridge chips to block.
