You don't have anything to worry about as you did absolutely nothing to your device. Your problem is you have to be root before applying the patches. Also the patches weren't really meant for average users, but here goes any way. Using filebox go to options, and enable root, next navigate to the BoostN900 folder and run the option "Open terminal here." Then you execute the sh commands from the first page, make sure you run Makebackups.sh first, even if it worked already...
