Tips.
Yeah portable electrical devices work better when you have batteries in them.
But actually being serious. Any points in that you thought were fiddly or learned a little trick that might help someone? Something that might avoid pinching wires or just make it easier. For instance I learned when replacing a shell on my original DS (hinges had long since gone pop) that aligning the rotary part of the hinge was a good plan and it might not have been immediately obvious to do that.
I would also note restoration today often sees people want to replace screens with a 101 screen mod, possibly audio mods, maybe fancy screen covers and the like. That looks like a full transplant so would probably have been easy enough to do there but do you have any advice for those that might want to pull a bit less apart to pull off such a trick?
