Can I replace mother board of 4th nano with a 2nd?
I have a 4t generation nano with a broken hold button, and I have a 2nd generation nano with a bad battery. Can I combine the two somehow or is it not possible?
I do not think that this is possible due to different sizes as well as changes in connections and logic board layout. Unless of course you are really good in modifying cases as well as logic boards. Sorry, but good luck. You may just find what you are looking for on eBay etc. The Battery and the hold button should be repairable and that would give you two iPods and lots of experience. Let us know what you are going to do .
