Can someone please help. I went to connect my ipod touch to my itunes and it told me that the ipod needed restoring and updating. Updated it and clicked restore - tried to restore it and came up with the message "could not be restored. An unknown error occurred (1604)." Any help would be appreciatd.
Ok, I've been trying to fix this for 3 DAYS!!! But, I finally found the answer an hour ago and my Touch is sitting next to me happily syncing away. Rather than let someone else go through the pain I've been experiencing I thought I'd share how I fixed this.
After trying all the various suggestions (re-installing, another PC etc.), this is what I did:
When you get the 1604 error click 'ok' but keep your iPod plugged in
Go to 'Task Manager' and find the 'iTunes' process
Click 'End Process' which will terminate iTunes
(Remember, don't unplug your iPod!!)
Start up iTunes again
iTunes will then recognise the iPod
Click 'Restore' and you should be ok
Some of the other suggestions might also work for you but just thought I'd give you another option.
Hi I have been going through the same thing too! Was going to do what you said but was scared when I got as far as task manager process and was given a warned that there might be undesired results loss of data and instability... is it still ok to do this anyway?
