I think some guy did it with the Note 3. But thing is, the AT&T modem on the S5 has not been extracted.

Extracting the AT&T modem is not a problem I can get it quickly using the stock firmware file. But, still i think it will brick your tmobile s5.

How so? Would it be the same as flashing a T-Mobile modem?

There's your answer right there. T-Mobile released a patch today to deal with poor SMS/MMS or texting issues. Doubt it has anything to do with signal.

Flash the latest T-Mobile update and then see it perform as you'd expect.
