Question

"My ipod is displaying apple logo and wont start up, hard reset leaves it the same, disc mode works but iTunes doesn't "see" it even if the computer does."
It worked two days ago fine, for two years, until I installed this newest iTunes update, then for one day it kept on freezing and going to apple logo screen mode, then today it only goes to that screen and wont start up at all.
I've tried the hold down two buttons hard reset, that doesn't help. I've tried disc mode... but iTunes doesn't "see" it even if the computer does.
This is a pristine ipod, never exposed to adverse conditions, never dropped, never wet, and it worked perfectly two days ago.
Can I factory reset it somehow? (considering itunes can't "see" it)
[Ipod classic 160gb less than two years old.]

Answer 1

Looks like I might have found the solution on a youtube comment:
R.O:
"Plug into you laptop first, whichever set up you use that has iTunes, i know it won't read it, don't even open iTunes as of yet. Do the typical reboot "Menu +Center button at the same time" and hold it, DONT LET IT GO like we were told, when the apple pops up.. KEEP HOLDING IT it will make a new ding sound I've never heard before. and since its hooked to you laptop already an error message pops up and says apple will need to download something to repair your iPod. I when u see that that when i let reboot buttons go. hit ok on the laptop something downloads for like 20 seconds then the iTunes icon hops around when you open it it has a screen with an iPod classic on it and says "Software version blah blah, iTunes will check for an update on such n such date" AND FINALLY there's a "Restore" button. click that and you will be back to square one with your iPod. Renaming , adding all the music on it, but it will work again, finally. "
I had to do it twice, because my mac froze the first time, but its recognized it now and is downloading the software as we speak...
Now I've clicked the restore button and it's restoring... I'll post again if its a success, otherwise assume failure.
