Reflash Cricket/AIO 520 to ATT ROM?

[inteller]

As far as I know all the bands are the same since this is the former ATT MVNO. Since Cricket is ******* over their 520/620 users I was wondering if this was a route for some people.

I think it's possible, but you would probably need to go with an unbranded ROM first. The AT&T ROMs are signed to work only with their hardware. I guess the signatures are tied to something on the devices. I just tried to flash a Cricket 630 with a GoPhone 635 ROM last night, and it failed due to the signature check.
