Hi, I’ve been trying to make my own iPhone 7 plus or 7(I still haven’t decided). I want a logic board (that is less than 100 $). But I just didn’t seem to get one that cheap. However I saw an unlocked iPhone 7 plus logic board for just 90$ in AliExpress. The seller claims it’s original!! Is it safe to buy??

No, could have some other problem on the board such as liquid damage / audio IC fault etc.
