I could have left the lineout signal intact, but that was actually part of the learning process. I was getting some really weird fuzzy sounds, so I thought that if I got rid of the elements at the place of my soldered wires, that would fix it. Turns out I had not properly grounded the stereo jack, so that fixed it. At any rate, I
think I disconnected the lineout, but I haven't actually checked. The headphone out does still work, if that's any consolation
Will report back after school.
I'm going to try the 5G diyMod for a friend. In the mean time, the rest of you DIYers can take confidence in doing it yourselves.
iFixit: iPod, iBook, & PowerBook Parts and Accessories and
ifixipodsfast.com have great guides on opening your iPods. ifixit has a pictorial guide, and the guy at ifixipodsfast.com has video tutorials. I couldn't stand listening to his accent after a while though. I was going to take a look at my dad's 5G iPod but he walked in while I was trying to disconnect the LCD screen from the logic board and understandably freaked out. He got a 3-year warranty on the thing, so neither of us wanted to mess that up (I didn't know until after he walked in and yelled at me.) =T
After seeing that picture of the 1G nano, I'm still kicking myself for having given it away. Having a really slim, portable diyMod nano would have been awesome.
