Can I flash the stock Tmobile ROM?

I just switched to Tmobile from AT&T and I'm wanting to use the full functionality of the Tmobile ROM, is it possible or will I damage my phone?
Did you change the sim or the full phone? Check your model number and find a rom with that model number and you should be good.
I am still using the AT&T SGH-1747 (d2att) phone. I just want to use the Tmobile ROM and I was wondering if it was safe.
You can also flash the Aroma based roms here for the d2att which will give you the option to flash as it were a T-Mo phone. (I'm guessing you have a d2att unlocked using T-Mo service) that will give you the correct APNs and build.props to let your d2att act as a d2tmo

Question about using ATT Rom

I have read that I can use a ATT ROM on my T-Mobile S4 and was wondering if I did so and then of course flashed a t-mobile kernel, if I would have wifi calling or not. I am not sure if that is part of the rom or not so wanted to just check.

You can flash an AT&T ROM, but flashing a T-Mobile kernel will not enable WiFi Calling, because it is part of the ROM. Sorry.
The way u wanna do it by flashing an att rom on a tmobile s4 more than likely
wont work cause the wifi call feature is built deep into the tmobile roms... AND ALSO WORKS OF THE SIM CARD.
On the other hand You should be able to flash any tmobile rom.... on a att branded s4 and get wifi calling just keep the att kernel..
And keep att baseband.
This should be no diff for s4 because
On the att s3 you can flash tmobile 4.1.2 roms and get wifi calling
If it uses aroma installer and opts to keep kernel...then keep the kernel but continue flashing tmobile rom...
Ive used many tmobile roms in my att s3 with wifi calling.
Havent tried it with a tmo s4 on a att rom.... just make sure u backup stock att rom if all else fails.

S6 edge Roms on s6

Can you flash s6 edge Roms on s6 what will not work if it will work at all. Also T-Mobile Roms. Do they work on sprint? Possibly just a radio and kernel flash to get them working?
Bump. I'm currently on 920V (Verizon) where roms are interchangeable. Does anyone know if 920P follows the same suit?
Edit: Found my answer. For anyone who still has this question. They are interchangeable as long as you flash unikernel afterwards. However since 920P & 925P are compatible, it doesn't mean you can flash other roms (outside of Sprint) without the dev's verification. So keep checking OPs!
I installed 2 different tmobile roms to my g920p sprint thats gsm unlocked . But baseband is unknown and imei also. Have you had any luck getting a gsm rom on these cdma devices?
