Default Flash Stock Kernel I9195 after Update to XXUBML1

First of all to all a healthy new year.

Unfortunately, I have made the update on the floor proficient product XXUBML1.
Afterwards my device grootet and my backup over CWM of the version XXUAMH3 restored.
Then the mobile phone did not boot up properly and I had to do the file flashed with it the mobile phone again runs.

Is it not possibly after an update on the proficient ware version XXUBML1 an old floor Kernel flashed?

Soory for my bad english!!!
