What I wanted to do now is switch to a newer firmware, but I don´t now how to do that exactly.
What do I need to flash to get the most current OS (In my opinion this is 4.19.401.8), where I got two files from, one from here:
http://xda7.androidrevolution.nl/db_...4.19.401.8.rar (seems like recovery only)
and the other one is: http://xda7.androidrevolution.nl/db_...4.19.401.8.zip
Main issue I have is that LTE speed is max 8Mbit/sec... and though I´m S-ON I don´t know how to update the current firmware without bricking my phone...
Thanks in advance
