You must make a flash of your phone. That means :
Firmware has two parts:
1. FS: It contains languages, images, sounds, animations, settings, etc. Anything that isn't pure software.
2. Main: It contains the software.
Note: MAIN and FS HAVE to be the same software version
MAIN R1BC002
FS R1BC002
Customization has to be same region as FS, in this case
FS = EU5 (EUROPE_5)
Customization =CDA102338/50 ( EUROPE_5 Sunrise Switzerland)
