Hi sir.

I had a problem in the initial power-up process.

I found that the screen was stuck in the attached picture. 

 Thank you

Hello, 

please try a total factory reset.
Remove the lithium battery (open backside)
Wait 2h, restart the device.try to update to the last version 
(contact Siemens technical support)

If restart is ok, install a new battery.
