do i need a firmware upgrade for my k800i?

All files are in download section, but first you need access to download section.

R8BF003

Yes, you need custom file.

Finalization = Completing flashing operations and storing basic settings that phone needs to properly operate [i.e. security certificates, (and this is why phone displays "configuration error" if it is not properly done)].

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)

Nice day
