So, I have an A1784 that was dropped and the back housing pretty much done

I was looking for a replacement. Will the A1661 take the A1784 motherboard?

Thank you!

Hello @gswartz

So the difference between the A1661 model and the A1784 model is that the A1661 model is the GSM and CDMA model of the phone and is compatible with most carriers. However, this is not the same story with the A1784. The A1784 is strictly GSM and is compatible with AT&T and T-Mobile. The frequencies that the carriers use to transmit the data are different and that may be an issue later on. That’s why you generally want to stick with swapping out logic boards of the same model only. As far as sizing goes, it will fit but whether or not it will work is kind of a complicated story of “ifs” and “buts”.

One good example is the iPhone 4. The iPhone 4 CDMA logic board will not work with the iPhone 4 GSM model as some of the parts are incompatible with each other. I’m not sure if this will be an issue if put in an iPhone 7 perspective though.

I’m going to link an iFixit thread that explains this as well Changing logic board from different carriers
