Maybe it can help, so here is my PhoneXS log:

12:18:58| Phone-XS GUI Build V2.10 Alpha Ready!

And my questions:

1) Should I replace the firmware with the newest R1JG001_RED52 or should I stick with the R1ED001 (as I have now)? I am planning to do it with PhoneXS. What is recommended?

2) What FS should I choose between: CENT_EUROPE, EUROPE_1, EUROPE_2, EUROPE_3, EUROPE_4 or EUROPE_5? (I live in Belgium and want the phone in French)

Thanks for your help!
