I have a SE Z520a that I want to recycle to a new carrier. My old carrier (AT&T / Cingular) gave me the unlock code which seems to work fine (I see unlocked icons for all five categories NCK, CCK, etc.). Now I would like to unbrand it.
Will pushing a firmware update via SEUS be sufficient? It look like the current firmware for this phone is R3J017 while the phone internals say that I am on R3F017. I assume that if I update via SEUS, I will get the latest and greatest.
If that is not sufficient, how do I get a generic branding? I know Davinci and some of those will do that, but I would prefer downloading software and doing it myself. I can't afford to brick the phone.
