Andboot issue

[elementyy]

I found and booted to XDandroid froyo 2.2 it was good but i found I didnt have file explorer. I found that I need to go to the android market on my phone and download one. It was okay when I went to settings -> Wireless -> Wifi and found that my wifi doesnt want to connect any network. It just says scanning...unable to scan...The application settings(process com.android.settings) has stopped unexpectedly.
And it was all the times. I tried soft and hard reboot - nothing.
I found some issues by downloading backup apps but I cant install them because I dont have explorer, wifi and cannot view my SD files.
The wireless should work on this build, I also have a wireless connection at home - It doesn't matter if it is WEP or WPA for me because it cannot find ANY network not only at home.
My friend has got the same phone and same build and same settings but he is running everything normally even wi-fi.
So if you can solve this problem just reply.
I'll give you the information you want.
