The newest (not necessarily best) firmware is R1KG001 and you want both the MAIN and FS plus the customization file

my advice to you is never use SEUS as it will upgrade your CID to 53 which can't be patch for now.

Customization = Changing or replacing original content of the phone, like ringtones, wallpapers, icons, themes, that come with branded or unbranded phones. It's nothing more than first default configuring of the phone after flashing FS file. Usually the process is:
1. Writing customize.xml and server&java certificates in tpa/preset/custom in sonics folder to tpa/presest/custom folder in the phone's internal file system
2. When the phone starts after flashing, it parses that xml file, puts settings written in that xml into the phone's gdfs and works out certificates (some go to Trusted certificates, some got Java certificate etc)
If you open customize.xml you can change almost any initial settings like time zone, date, internet profiles etc.

Branded Phones = Some network providers place their own ringtones, themes, icons, links etc within phone's software. (eg. vodafone, orange, t-mobie, rogers, cingular etc.) Debranding means removing all this content and restoring phone to it's original factory SONYERICSSON condition. This will not damage phone in any way! You will loose Operator Icons, and links, WAP, and MMS settings however these you can get via http://www.sonyericsson.com/spg.jsp?...=pg&tl=support
select Region ---> Country ---> Support ---> PHONE SETUP

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)

Have a nice day

i fixed the white screen error with my phone when i flashed but now service provider is locked i have cid 49, downloaded firmware RLKG001 but the main_generic doesn't install?? any ideas what i should do?

and what do you mean the newest is not really the best? whats the most stable version for a w850 now?

do u have a otp 49 or flash cid 49 ?

philfog

my cid is 52 i updated it with XS after i flashed my firmware to RLKG001 because my phone had a white screen, everything is unlocked except the service provider. Thing is the firmware i took is generic why is it still locked?

Because you didn't unlock it. I think you're confusing "unlocking" with "debranding". Read :
Remove SIM-lock patch generator - Top Sony Forums

use X++3.2 or far+jdflasher

the phone was obviously unlocked via patch, so any firmware you flash generic or branded will relock your phone....

use x++3.2 to slove it

Where can i get the MAIN and FS and the customization files for W850i...

look in the download area at the topbar of this page "Downloads"
