[German]In this blog post, I provide advice on how users who have been surprised by an automatic firmware upgrade on HP printers can get the devices back to the previous firmware, if necessary. This is helpful, if an unwanted HP firmware update blocks the use of third-party ink or toner cartridges on a printer. The article is a brief summary of hints given in various blog posts and the reader comments made there.
HP blocks third-party cartridges via firmware
Hewlett Packard (HP) has a nasty surprise from time to time for its customers: They are blocking the use of third-party cartridges via firmware updates. I reported on this practice the last time within my blog post HP firmware update for ink/laser printers blocks third-party cartridges (Nov. 2020) – but there are other posts on similar actions at the end of the article. Thanks to these articles, I get to know relatively quickly when such an HP action has happened again..
The hurdles of firmware downgrades
HP printers do not have a simple button to switch back to the old firmware after an automatic update. Users have to do downgrade manually by installing a saved old firmware version onto the printer. Blog reader Matias de Goycoechea posted instructions on how to proceed in this comment (thanks for that). I can't test it due to lack of a printer, so note that downgrading is at your own risk.
There is another article here, providing hints for installing firmware updates on HP printers (and with an old firmware, it's a downgrade). User fmillion had summarized his steps within this reddit.com post. Some users are reporting trouble installing the firmware, so be sure not to use a Wi-Fi connection. Unplug the LAN cable, uninstall the LAN drivers, connect the printer via USB, and install USB drivers. After that steps try to downgrade the printer firmware using the methods outlined within the linked articles.
Just in case you still run into issues, browse the comments within my article HP firmware update for ink/laser printers blocks third-party cartridges (Nov. 2020). My readers have given several hints, what to do.
Where to obtain old firmware?
The biggest problem is probably getting an old firmware version for your printer. There are some links in the comments of my blog post HP firmware update for ink/laser printers blocks third-party cartridges (Nov. 2020), so you might get lucky. However, the links my break or time, because HP very quickly removed all older firmware versions from its pages. You can visit this page and check, it a firmware for your printer is available. And there is a German site Fairtoner offering a contact form to obtain older firmware versions for the following devices:
HP Color LaserJet Pro M 254 dnw
HP Color LaserJet Pro M 254 dw
HP Color LaserJet Pro M 254 nw
HP Color LaserJet Pro MFP M 280 nw
HP Color LaserJet Pro MFP M 281 fdn
HP Color LaserJet Pro MFP M 281 fdw
HP Color LaserJet Pro MFP M 281 fw
HP Color LaserJet Pro M 154 nw
HP Color LaserJet Pro MFP M 180 fndw
HP Color LaserJet Pro MFP M 180 n
HP Color LaserJet Pro MFP M 181 fw
So if you own one of these printers and need a firmware downgrade, but don't have an old firmware version, maybe the sources given within this blog post might help. But note that I can give support, that links my break, and everything is at your own risk.
