1.Chiose main and fs(ensure both FS and main are the correct CID for your handset) Go for generic.
2. XS++ V2.0
3.DCU 60 cable. If you have an SE phone youll have this!
4. Flash drivers
What you must do?
1. Download the program from 2shared - download XS++.rar
2. open xs ++ Ensure that you select the correct Phone from the pull down list!
3. Download the firmwares from either topsony and similar site.
4. Check Flash Main tickbox and select your main firmware file
5. Check the flash FS tickbox too, and again select the FS file
6. Check the customization tick box. This is the important part. This is what stops you getting the configuration error on startup. It uploads certain files that the phone requires to start.
7. You can also change the CDA should you feel like it. Most of you will want Europe_2 generic but my phone is M_EAST_N_AFRICA. There is a list of CDA's on topsony that will tell you what each one is.
8. Click flash and wait for about 4 minutes.
9.The software will tell you when you can disconnect.
