So I’ve purchased two faulty Xbox Ones off eBay… Unfortunately it looks like someone has already opened them up to take out the blu-ray lens and hard drive out of the machines. Luckily both of the daughter boards are here, but there are both packaged together. Is there any way to identify which daughter board belongs to which motherboard? If not, is there any issue with swapping them around if they don’t work first time around? (No e-fuse or anything like that?) Thanks!
Unfortunately there is no way of identifying which one goes where. It won’t hurt anything to try them and see which one works.
