[Q] Unlocked AT&T S5 on T-Mobile

I recently unlocked and rooted my AT&T Galaxy S5 to use on T-Mobile network. However I still have AT&T firmware on the phone, and I'd really like to flash cyanogenmod, or at at the very least stock T-Mobile. Is there any way to do this? Thanks in advance!

Don't know if there is a Cyogenmod available for your model (SM-G900A) but there is an AllianceRom which is built off the T-mobile SM-G900T firmware which will work on the AT&T S5. However, since that version of the S5 has a locked bootloader you will need to use Safestrap Recovery instead of TWRP. You might want to look among the threads in the AT&T S5 area of this forum for more information and maybe ask your question there. I brought my unlocked AT&T S5 over to T-mobile and used it for a few months before getting a T-mobile S5. AT&T stock s5 firmware worked fine. I also did try out AllianceRom on that phone briefly but stick with stock. I don't think rom slots ever got fixed on Safestrap so only the stock rom slot could be used for flashing which is one of the reasons I chose to stick with stock on that phone.
