Lumia 635 firmware swap
I just acquired an AT&T Lumia 635 and it currently has windows phone 8.1 on it. I have put in a request with AT&T for a SIM unlock code and I am awaiting the code in my email now. After I unlock it, I would like to switch the firmware over to my carrier which is T-Mobile. I have experiencing basic flashing androids and blackberries but now windows phone. Can anyone tell me if this is possible? If it is, can you provide me some links to an official T-Mobile rom and detailed instructions on how to install it. IF an official T-Mobile ROM is not available, I will settle for an official Microsoft Vanilla ROM. I am not interested in custom firmware AT ALL. I messed with cyanogen before on androids and got to many error messages for my taste.
