Replacing a note 4 screen (N910F) - will it work with a N910P Screen?

I have a N910F digitizer + screen that needs to be replaced.
I found a N910P digitizer/Stylus Flex + frame, just have to move the motherboard to it and reattach the ribbons.
The question is are there any difference between these two?



Another question; the volume button is a little wonky, I have to press on it really hard (the button on the motherboard not the physical button on the frame), is soldering required to replace it?

Thank you.

replacing a broken volume ribbon?

I ripped the old volume ribbon while doing a screen repair. Now the screen works (Yay!) but I'm having to screen widgets to adjust volume settings(Boo!).

I found the part I broke on Alibaba and on ebay, but I can't find any instuctions on how to replaced it.
(I can't post the link but I googled: "Volume Button Flex Cable Ribbon Replacement For Oneplus One" and that will show you the part I'm talking about)

I'm pretty sure I can desolder the broken part and solder the new one, but I'd feel more confident with some sort of tutorial.
Anyone seen any? My googling hasn't showed anything specific to OnePlus but I did find similar processes for older phone components but they look larger.

Any advice? Am I posting this in the right place?

Thanks!
