After so many freeze and usb connection issues(by the way, connecting after "full stop of ipod's hd" works) today I've decided to uninstall. I had to as I'm gonna give it apple to replace the battery anyway. emcore's uninstallation procedure requires: starting iTunes, connecting to pc, pressing menu+select for 12 seconds(it reboots emcore in 8 seconds or so, then after the left 4 seconds the screen goes black, at that moment you have to stop pressing, or it reboots again and you have to do it all over again) to make it recognizable as apple dfu device by your pc. If you apply these steps correctly iTunes is supposed to recover and download iPod's software for a new beginning...nope..it doesn't work that way. after dfu mode, pc either can't install dfu driver or recognize it as a freemyipod.org dfu device which won't trigger iTunes to recover it. Uninstalling iTunes, reinstalling it, installing older versions(in my case 9.2.1), trying other usb ports, uninstalling the driver via device manager, reseting ipod over and over again and trying everything step by step again....won't work! Solution: Just use another pc with internet connection and the latest iTunes installed!(older version doesn't work as it says it can't connect to ipod update server). iTunes on, ipod in dfu mode(12 secs)...iTunes first downloads a recovery part, then asks you to click on restore, then downloads ipod's latest software...."welcome to your new ipod"
