first off, im not really a techie so i'll have a hard time grasping the commands and terms.

i rooted my nexus s and tried to install cmg9 but the download failed and i was stuck in an error loop "setup wizard has stopped working" i tried restarting and still the same problem comes up. panicked, i did a memory wipe on the recovery menu and lost the "custom framework" (i forgot what it was called) that was needed for the backup. now, i have no idea to return the phone to its original state since im still stuck at the looped error.

i found this "one_click_stock" application for windows but wont work because my phone is conveniently stuck and cant change the usb debug thing.

if anybody can help whether restoring the phone or being able to enable the usb debugging through windows command prompt or mac terminal, you will be forever in my prayers!
