I am trying to update our M127 devices to the latest firmware that resolves the Ripple20 vulnerability. The firmware updates are not working. Nothing happens on the printer side even though the firmware update tool reports success. Restarted the printer after the update. Same firmware. I've confirmed that the PC and printer are communicating with Wireshark.
Anybody else have this issue?
Firmware is here:
This one(13MB) looks like it is updating but nothing happens on the printer side:
This update(22MB) just quits when I click "Update":

You can check the embedded web server under settings>security>administrator settings as it is possible to disable firmware updates, which makes it look like the firmware install is successful but it does not actually install.

I thought I'd try installing an intermediate firmware update between my printer's current version(20150818) and the latest ones. Maybe a two-step upgrade would work? The problem is I only see these updates on HP's FTP site:
-rwxrwxr-x 1 ftplib 34572848 Dec 6 2015 M127-M128_Series_FW_Update-20140526.exe*
-rwxrwxr-x 1 ftplib 14037912 Jul 16 19:09 HP_M127_128_FW_Update_20200602.exe*
-rwxrwxr-x 1 ftplib 23551856 Jul 16 19:09 HP_M127FW_128FW_FW_Update.exe*
There must be more than just these. Does anybody know of an official HP source for other firmware versions?
