Image update on active MPad without external keyboard possible?

[florrens]

Hello, is it generally possible to run an image update on an active MPad without an external keyboard? I currently have a hot-plug MPad from 09/22 where the screen with the runtime selection does not respond to any input on the touch screen (if I start the MPad without the image stick the touch reacts, so it is not broken). I managed to to run image updates on other MPads without having to connect an external keyboard and just use the touch screen instead to start the image update (push the green arrow)

The engineering guide in CpS says that I have to connect keyboard + Image stick - is this always mandatory or are there cases where the Image stick is enough?
