While freeing some space from my device, I may have mixed up a map file with another 500 MB img, which I deleted as well. Seems it was some part of the operating system.
The startup process seems to be normal at first, but then stops with 3 running dots and message "Loading courses, workouts and locations ..."
What I tried:
- soft reset with the hardware buttons - same behaviour as described above
- connecting to PC - does not show up as device, linux debug messages:

Charging still works.
