How can I Debrand an AT&T Lumia 640

[lift]

There is a great guide to Debrand an AT&T Lumia 635 that I used and it worked great. However, there is no guide yet to Debrand the GoPhone Lumia 640. The guide for the 635 does not work on the 640. I have tried to flash other ROM's to the GoPhone 640 but AT&T has it locked down and no other ROM will flash. The AT&T 640 needs to be Debranded first. Any Guru's out there been successful?

Nope, but I'd like to know how to change the name on the phone icon so it doesn't say "Cricket".. it's a Cricket SIM. Not the end of the world. Not hijacking your thread, just sort of on the same topic.

We can't debrand the ATT 830 sadly, I'm not confident we can with the newer 640.
