Updated: November 1, 2023- If you are still struggling with this issue, here is the official web page from HP with links to an updated firmware that fixes the problem as well as instructions. https://support.hp.com/us-en/document/ish_9370176-9370307-16

 

My original post is below.

 

Many users of 377, 477, 577 and 57750 MFP units and related print only units are finding that the printers are freezing or not responding. This issue is caused by a corrupt firmware file(Version 2337B)  that was automatically pushed out.  There are a few different methods to fix this problem, mine has been shop tested on several machines and resolves the issue. The problem appears to be caused by a corruption of the networking portion of the device. Follow the steps below and you should be able to restore the function of your device.

  1. First step is to go to support.hp.com and download the current firmware update file for your device. The problem firmware has been withdrawn and we have been installing  2313A successfully.
  2.  You will need a USB thumb drive, ensure it is formatted in FAT32.
  3. Next you will need an archive program like 7-zip. 7-Zip allows you to directly open the downloaded file without having to rename it. Once you open the file you will see one file with the extension .FUL2. Extract that file to your USB drive.
  4. On  your printer, disconnect any wired ethernet cables. If you are connecting via wireless, turn off the wireless signal in your house if your printer is connecting to that. Any live network connection appears to cause the lockup. Then reboot the printer. If it will not shut down from the power switch you will need to simply pull the cord. Not preferred but sometimes there is no choice.
  5. Once the printer comes to ready, insert the USB thumbdrive into the USB port under the keyboard. A USB icon should appear on the control panel. When you see that logo touch it and you will be presented with 3 icons, "Print" "Scan to USB" "Upgrade detected"  In some cases it can take the printer a few minutes (I waited almost ten minutes on one device) for the upgrade icon to appear. Once it appears, touch it and the upgrade/downgrade process with start. Once it is complete the control panel will return to regular state.
  6. As a safeguard, disable automatic updates before reconnecting networks. The easiest method to disable updates is to press the gear icon in the upper left of the screen twice, scroll down to printer maintenance then printer updates and then printer update behavior and set to any option but auto-update.
  7. Once you have completed all the above steps, restart the printer, connect your network cable or turn on your wireless and you should be back in business.

If you access the https://support.hp.com site from a Mac, you need to select Windows 10 as the OS at the top of the page to see the Firmware in the dropdown list.

Do you think Best Buy can do this to my printer? Checking see if the issue is the same as my printer will not boot up at all and gets locked with the hp screen in the initializing screen on the window.

I tried to do this, printer sees the USB stick but doesn't see the firmware so doesn't offer me the option to update before the screen freezes. Any ideas?

  • TO:  Repairatrooper or an expert on this

I have unit 57750.

Anyway possible to downgrade from 2337b / or 2340C to 1921e or 1908c firmware to use expired HP ink or third-party inks? I have a few new expired ink and this new firmware would not let me use them. I tried to use the blue screen to drive reflash options with both 1921 and 1908 but Newer firmware kills older versions.  it seems like the new version has a kill switch to not downgrade to older firmware. If anyone has some success stories please let me know. on 577 printers. 

 

thanks,
