This is an SD install thread. Why do you need to restore stock? Explain a little bit more what you are doing.i am having the same issue where i flashed CM 10.1 and it was stuck in a boot loop. i wanted to go back to CWM to restore the stock rom and now cyanoboot is stuck. i tried the method described with the holding of the buttons but nothing... any idea? did i brick it? i hope not...
