Just wanted to report that work has gone under way to make a tutorial for the diyMod 5G. The only thing is this board is much, much harder for me to figure out than the 4G click wheel. Basically, the trace is hard to find from the pin, and once I post some pics, you'll see what I mean. The dude at this page
has picture of some very obvious caps that go to the headphone out, but I'm not finding a short between the line out pins of the WM8758 chip and either side of the caps, so I'll keep investigating.
The closest I came to anything was an increasing resistance between the line out pin and one of the pads of the huge capacitors, starting around 1400Kohms and slowly climbing up to 1600Kohms as I remove the leads. I suspect some current [from] the DMM caused this odd activity.
Opening the iPod video was difficult on its own, so beginners may want to take caution. This iPod is extra annoying not only in its complexity, but also in the ludicrous amounts of adhesive used. Once you remove some of it, it's near impossible to put it back to its previous effectiveness. It's not that the logic board necessarily needs that much adhesive as it's all pretty cramped inside anyway, but I guess Apple wanted to be doubly sure of its security.
This has gotten me to scratch my head quite a bit. I'm beginning to question whether or not it's worth the trouble. I know this feeling will pass, but it's greatly frustrating working into the wee hours of the night (wee for me anyways) with a full day ahead of you and getting nowhere. If anyone would care to open up their 5G and explore with me, that would be of great assistance. Better yet, if someone would open their 5G iMod...
Alas, my bed beckons me, as I have many pages and hours of studying tomorrow/today. Help would be greatly appreciated.
