Cool!
1st I thought it doesnt work for me!
But after the following two steps it worked:
- Set back/reset the network settings (system=>advanced=>reset options=>reset WiFi, Bluetooth and mobile settings)
- (dont know if necessarry) restore default settings in the developer options (last setting in the dev opt list) and disable the developer options afterwards.
@sydpol
The network reset should be added to your howto! THX a lot for your research!

Disappearing of some widgets after saveboot is normal.
I sync my contacts with the DAVx5 app to my own private nextcloud server and nothing was lost or had to be restored after the saveboot. I recommend this setup to everyone!
