Urgent issue, 40-second or Quick restore not working as expected!

Hello,

I installed Entware and Docker to my PR4100, made some changes; however got some error and decided to reinstall everything from the scratch.
I tried 40-second reset and Quick restore from the UI; but apps not removed completely and device is restarting automatically without my control. Getting started wizard is shown at the first login after quick restore, but I can see manual installed apps that I want to remove.

Do you have any sudgestion or solution to go back to the factory defaults?

Thank you.

Boot without the disks inserted.
