So i've managed to solve the problem, not the way i wanted but still it's a working solution.
I have cleaned everything, changed to an old without brand 2Gb microSD, and installed this rom 'Dynamics_HD2O_HD2_2_21_Western'.
After all the configurations, including a valid serial, the internet explorer works only in google search page.if i type anything else it quits.
The solution is here: with this rom i was able to download Opera Browser, and it's the only browser that supports 'web surfing'
in this device.
I still donīt know what can cause that strange behavior in IE but opera is a great browser (that i still use in my N8) and works like a charm.
Thank you ' dxdy ' for the help, and if a forum admin want's to lock this topic is finne by me.
