I just bought a galaxy s5 model sm-900t! I'm pretty sure its a T-Mobile model phone. But I have at&t service! I have read that at&t has there bootloader locks and the only recovery for it is safetrap recovery. But T-Mobile has unlocked bootloders and phills recovery will work just flash through Odin. But I'm not sure do I flash the mobile number sm-900t as if it was T-Mobile? Or do I flash at&t recovery bc of the service that is on the phone?? Thanks for any help you can give me..
