HP DeskJet 2675 - EWS asks for a password after a factory reset

[IndioAR]

I've forgotten the password set to my DeskJet printer. After reading several docs, I've reset EWS to factory default by pressing X button and WiFi button at the same time until it blinks. Now it does not connect to my WiFi (because it needs a password, according to the USB setup steps). HP Smart on my Android, the same (cannot configure the WiFi, and the process aborts).

Is any way to *really* factory reset the printer? Versions running:
HP HTTP Server; HP DeskJet 2600 series - V1N02A;

Thanks in advance!

PrintScanDoctor did not help, as it works through USB wire. This app seems that not checks the admin password status (which is what I want to reset)

Current firmware version is THP1FN1923AR

Impossible to downgrade. It seems that in an effort to make it super secure, it resulted not functional at all. I tried to get firmware version 1518 (perhaps the previous one, before CVEs) but cannot download it from anywhere. Any clues?

I've fixed it by myself. I sent a factory reset snmp command and voilà.

snmpset -v 1 -c public 192.168.223.1 1.3.6.1.2.1.43.5.1.1.3.1 i 6

Power stood blinking. I unplugged the power cords, plugged again and the printer was *really* reset to factory defaults. I went through the setup process without any password request.

To complete information: in order to get connected to the printer to send SNMP set commands, you can reset the printer's network ("Network" + "Cancel" buttons ~5 secs). After blinking a while, you will see a wireless network with the name of your printer (and some additional garbage). Connect such WiFi, you'll get a 192.168.223.x/24 IP address. Your printer should be 192.168.223.1, then you will be able to send the SNMP set command.

Good luck. HP sucks.
