I have a C1111-8P unit that I am configuring and learning at the same time.
The unit had firmware 16.12.01a
boot-start-marker
boot system bootflash:c1100-universalk9.16.12.01a.SPA.bin
boot system bootflash:c1100-universalk9_ias.16.10.01b.SPA.bin
boot-end-marker
stupid me, I upgraded to the sdwan image and to this specific version c1100-ucmk9.16.12.3.SPA.bin.
Now I cannot see the device in my network. I guess it has an empty config.

How can I go back to the universal image?
---edit---
I found these instructions
https://www.cisco.com/c/en/us/support/docs/routers/xe-sd-wan-routers/214519-how-to-downgrade-router-running-ios-xr-s.html
are these still relevant or they have changed?
