Soft Keys dont work Help.

[rosman21]

I have a rooted fasciinate and many questions to be answered and I need help big time. First, I accidently deleted the stock browser i found the apk i put it on my sd card and it when i try to install it says application not installed. i just need the stock browser so i can use xscope ver 6. If you guys can help me with that i would appriciate it. Secondly, My setup wizard is not working. i hard reset my phone which was today so i can somehow get the stock browser back but now the setup wizard dont work it always force closes. Please help. Lastly, I believe since the setup wizard doesnt work now my home, menu, and search key dont work. Only the back does. The soft keys light up but no vibratiion feedback or nothing they dont even work. Pleas ehelp me i would appreciate it. Thanks.
