LaserJet Pro MFP M127fw firmware update

[Matthew792]

I unpacked files with 7-Zip

Copy this file

.\HP_M127FW_128FW_FW_Update\PF\HP LaserJet Pro MFP M127FW-M128FW PCLmS/product-update.acl

... into this folder (Replace the ~11mb product-update.acl with the ~22mb version)

.\HP_M127_128_FW_Update_20200602\PF\HP LaserJet Pro MFP M127-M128 PCLmS/

Then run
.\HP_M127_128_FW_Update_20200602\Setup.exe

while printer is connected to your network.

Thanks Matthew, this worked in terms of updating the printer to 20200531, but unfortunately the printer still does not connect to HP's Apps service, and the latest firmware from HP's website still does not install. So as before, the printer is still useless for scanning multiple pages to email, the main reason I and many others bought this device. 

HP, surely you must be monitoring this thread, can you please give us some insight as to when we can expect this to be fixed? Thanks!

The problem is that HP's Cloud Certificate (which is basically their signed public key) has expired. So your printer will NEVER connect to their network without a authenticated public key, which comes via the certificate, which is in the latest firmware only. 

So, HP, you guys really screwed up this one. Why didnt you make sure your firmware worked?!

[speedf03302]

I followed your steps, the update pushed for 0531 or 0602 BUT not for the november firmware. HP I need the cloud certificate to use the printer!

@shlomil Any help here?

The latest firmware isnt actually updating anything. it falsely says it updates and were all missing the CLoud certification so we cannot use hp cloud services! .
