Be careful with the heat gun!! Don`t use it too much. You can melt something inside, specially when you`re closing the iPod.
Hello, first of all, congratulations on the great guide!
I`d like to give a hint. You don`t NEED to go through all the steps to change the battery. You can skip STEPS 16 to 23. You don`t need to actually remove the logic board to change the battery. Just desolder the connections and pass the riboon below the board. That`ll save some time.
Another hint is BE CAREFUL with the heat gun. I used it too much and I think that I`ve damaged something. But it was my fault =[
Great guide, thanks!!
