V10 with G4 radios?

I have the T-Mobile v10 that I'm using in Canada. Problem is that LTE band 4 doesn't work, it just stops working after a while. My wife has the G4 and is with the same cell carrier and her phone has no issues with band 4 LTE. Soooo I was wondering if there is any way of flashing the radio on the g4 to work with the v10. Maybe it will resolve the issue.
I don't know if this method is even possible so that's why I'm asking here.

Thanks.
