[Q] Nasty problem topic

Hi folks,

I have a nasty problem with my S8530. Somehow or other it got ****ed up. When I start up the phone, it boots, shows the screens where I need to type in my PINs, then I have to configure language, time and so on (it looses these settings every time I remove the battery, whyever), then I see the home screen, but all of a sudden it reboots. I can't do anything with it.
Folks, is there a way to recover from this misery WITHOUT loosing all my data?

Thanks in advance!

Cheers, DFahren
