Hello
1. and 2. 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 Sony Ericsson - Sony Ericsson
select Region ---> Country ---> Support ---> PHONE SETUP
No.
3. I use it about every 6 Month to see if new upgrades came for my phone.No.
4. How? When your phone doesn`t start. But you can look here how to debrand your phone and how to repair bad flash: xs++ 3.1 guide
5. Yes.
6. Look you connect your phone to xs++ and copy here your log from phone.
6.a and 6.b
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
