Why I must install it by roll back?
As mixmar said, in newer firmwares (2018) ability to install online-FW via USB drive was locked. (your version 04.25.70 already has this limitation)
If you need to install version 04.25.72, you have two options:
- via rollback method (described in first topic of this thread)
or
-via service menu (in section System 2 change parameter NSU mode)
