So, I reinstalled it - it's tantalizing, in truth

Some things though:
1. I notice I can not connect the device to my computer now, it tells me that the SD card is busy. Any fixes for this?
2. KPackage asks for a root password, despite having obtained root from terminal by using becomeroot. What can we do to rectify this?
3. Trash does not work. What's the deal?

Thanks for the help guys.
