SOrry if i haven't answer you question probably.
1. No, i haven't install rockbox. I want to install rockbox that's when i find out that my ipod is not working
2. When i tired the reset procedure, i can hear click click sound - it sound like the ipod is trying to reset or might have rest and trying to startup but fail many times. Because i tried it many time and each time i hold longer then before. the last attempt i held it for nearly 2mins.
3. When i connect it to to my comp using the USB there is a click sound and follow with the sound of the disc spinning inside my ipod but nothing happen, no light, no charger icon, no apple icon nothing just a blank screen.
