Let people downgrade from April 2019 and Dec. 2019 firmware upgrade that blocked compatible inks.

[kheselden]

I am FURIOUS and would like the DOWNGRADE  private message option too.  I have been through the pages on HP for the last few days which lead to me being told my INK - HP INK Geniune ink was counterfeit by you as there is no hologram.  I have now ordered directly from you for replacement ink and guess what - no hologram.  So its nothing to do with the ink.  Here i am again searching only to discover this feed (and others) that its the FIRMWARE  that seems to have caused a fault with everyone printer.  I am soooooooo  ANGRY right now.  I have fallen behind on things i need to do.  I really need rid of this update - urgently please.

Firmware Version EDWINXPP1N002.1942A.00

Same thing here, with exact same firmware version.  

Really HP, you should be ashamed.  

When I chatted with a service rep the person said, "oh well," and then then told me to trash all my ink and buy OEM.  This is not a joke.  I am furious.

It is a company's decision, contacting support as u relized is useless. Hp itself has to change its mind.

[Centounesima]

I got the same update of yours recently EDWINXPP1N002.1942A.00 and fixes nothing.

I found a NON OEM ink that works with 1942 on a 7740--IKONG.  Try them.  The rest--KOGAIN and VALUE TONER do not work yet as they have not updated their chips.  There is another company, LX I think, that I am not sure works yet.   I may try them out.

The OEM ink all works great, of course.

[Centounesima]

Glad to hear that. There is a good chance that 3rd party ink manufacturers will update their chips soon, but the issue itself remains, and Hp did nothing to help. Thanks for sharing.

By the way, I looked for the ikong 953xl on the Italian Amazon, but I could not find them. If u wanna share a link to the item u purchased it would be a plus.

Thanks.

I am shopping in the USA.  And I bought the 952XL pack, not the 953 as those do not work in the 7740.  The 956 cartridges also work in the 7740.  Try a search for the 952 and see that you get.  Also, try searching for HP 7740 INK and it should bring up a bunch of options.  If you do not see IKONG try another brand, BUT email them to ask first.  I emailed IKONG before I ordered to seek assurance theirs would work with the 1942 firmware upgrade.  They said it would, and they were right.

[Centounesima]

953 work too on the 7740. Anyway let's wait for hp.

Searched for the 952 from ikong; same result. Anyway i contacted another vendor that told me their cartridges work. Ordered them, waiting for the delivery.

Well, after contacting HP Support US, UK, France, Belgium, Germany, I had the same answer from every single one of them: I have to use HP Cartridges in order to print with an HP printer. I´m sorry HP but this is just annoying and totally not acceptable. They also say that there is no possibility to downgrade the firmware...not true. 

I have just downloaded the "1849A version", installed it and voila ... I can print again. 

So, what a waste of time talking to HP Support.

how were you able to install the older firmware? mine REFUSES to install it and i am stuck with the s-h-i-t-t-y 1910 that is ruining my life and making me lose work and extra money. if i don't find a solution, i am going to throw away my printer, which cost me a bundle when i bought it, with all the cartridges, which also cost me a lot, and switching to epson or canon tank printers. not even gonna consider hp tank printers! this is the second time they play the dirty firmware game.
