I have the F930BT with the old 2011 firmware , and tried the 2015 update , but it failed , incorrect sd card notification , after a lot of research succeeded installing the 2013 version. Does anyone know if you have to upgrade first to 2013 in order to make the 2015 update?.
I would like to have the 2015 update but am a little afraid i might brick the system again.
It's a bit confusing here because most of the topics are old and or the links are dead , and most of the members English grammar isn't that great...
