N910T with 5.1.1 vs N910T3, GPS performance?

like many others my GPS is just awful on my note 4. Do I have any hopes of it being fixed with 5.1.1 on my SM-N910T or should I just try getting the SM-N910T3 as a warranty replacement?

Help! --> N910T Odin PIT Partition FAIL

So my new Note 4 was in a bootloop when I bought it. So I researched and used odin with cf-autoroot and twrp to flash cyanogenmod. This fixed the bootloop.

But I want stock. So I downloaded these:

From this thread: http://forum.xda-developers.com/note...overy-t2902574
And then tried flashing the full firmware. It failed saying "missing pit" or something.

So I searched and apparently *.pit's for N910T are rare and the one's that have been posted by users on XDA have been removed because they were bricking.

I proceeded to search for a *.pit and found this: http://www.droidviews.com/how-to-ext...alaxy-devices/
I extracted the *.pit using adb shell when in TWRP, downloaded pit magic, and then compared my pit with another user's n910t pit in the comments.
User's PIT:

My PIT:


So seeing as they were the same if not extremely similar, I added the pit along with the full firmware and tried again on Odin.


Am I supposed to use the other firmware files and such when flashing with a pit at the same time? Like the bootloader, modem, etc.?


All I want to do is to re-partition the whole device, and "flash"/restore the stock firmware.

Thank you guys for your time reading this; sorry for my "flashing illiteracy" or what not...
