I switched program/method... Wotan now works but not TMS for some reason.
All I need to do now is to try finding out which firmware I had before using SEUS.

Instead of creating a new thread I continue here with my wounderful questions ;)

I have CID49 and have no intrest of getting new firmware, only downgrade/rollback so the bluetooth is working with my Car Radio again, it's only to choose firmware and language to install?
With SEUS I have firmware R4DB005, does anyone know which firmware the W810i phone was shipped with? =) That's the one I want...

@Speederer: Thanks for all your help and patience.
