praegler Posted June 5, 2014 Share Posted June 5, 2014 I have an unlocked AT&T Galaxsy S4. I am on T-mobile and the phone works, but I either get 4g-LTE or Edge. I did the research and found that the AWS Bands that T-Mobile uses for it's HSPA (3G) are disabled on the SGH-I337 AT&T S4. A little more searching and I found the web site: http://galaxys4root.com/galaxy-s4-tutorials/how-to-enable-t-mobile-hspa-aws-bands-on-att-galaxy-s4-sgh-i337sgh-i337m/ I have followed the instruction on the site (with the exception that I had to use *#0808# instead of *#7284#), but when I get to the the part where you recover the 337_AWS.qcn, I get the error "Received an invalid command from the phone" Has anyone else gotten this error when trying to enable the AWS Bands on your AT&T phone and how did you get past the error?
