problems flashing my K770i

[jasmin]

Look at this example:

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)

Did you pick right custom file? Because if you don`t pick right custom file, then doesn`t work.

Nice day

Dear Jasmin,
Thanks for the help.
I picked the only EUROPE_5 Customization file existing in the K770 folder.
I also learned that I might have picked the wrong FS and MAIN versions. I picked the only ones that I saw existing for EUROPE_5, that is the R8AA018. It might have not been the right one and I do not know which one I had. I tried to follow the instructions for the recovery from a bad flash using the back up but my phone still shows R8AA018. So at this point I am kind of lost (again!)
Thanks for your help if you can.
