I need help unrooting my LG G3

I recently bought (In the last 3 weeks) a LG G3 from MTS and rooted it but I tried installing a custom rom and it soft bricked my phone. Now my question is what do I do? I now you have to install the stock firmware onto the phone and know how but I am wondering which firmware to use. When I open my phone's back and read the top left corner it says D850 and under that it says 0827, now when I take out the battery it says M/N : LG-D852 at the bottom right corner of a sticker. Now if anyone could help me by telling me which firmware to install that you be wonderful. I am in Canada and my carrier is MTS if you need to know. Thanks in advance.

Try installing the ROM again, or install the stock ROM.

There should be a large LG on the upper left of the sticker. Then a barcode. Then an LG-xxx on the right. That's the model number.
