hi not sure if you figured this out but you have your order wrong. you have to cd into your Downloads folder first and then chmod the app before running the app. "cd" stands for change directory so from your home directory (which terminal denotes as ~), cd Downloads, and then do chmod -R 777 TOUCHSTARVED-SILICON.2.app (chmod stands for change mode and 777 is the code for read, write, and execute permissions so you're changing the mode to full permissions)
