Noob tried debranding cell phone, think I messed up

Hi Yall,

I tried debranding using the A2 Uploader, A2 CDA File Generator, SEUS method, but every time I tried that it said I had the latest firmware installed so I tried using A2Uploader method and I flashed it using C905_R1FA035_FS_APAC-ANZ_RED53.fbn but

A) I don't know if that is the one I should have used
B) What to do now?
C) Will it work with that firmware. I'm located in the United States and AT&T is my service provider.

Also my phone is a C905a. When I turn it on now I get this error message, "configuration error. please contact your network operator or service center." It does show the Sony Ericcson Boot Screen but this it comes up with that message.

Yes I am a newbie on this, but I've done similar stuff on PC's thats why I gave it a shot.

Please Help.


Thank You,

You might try again but I know with some cell phones you only get 3 tries to unlock them. then they go into a hard lock. This is a feature put into place by the provider. If you do not succeed then your only choice left is to take it to an At&T store. Fabe

I've got it resolved but thank you Fabe for the info. I wasn't actually unlocking it I was debranding it so I could use my own MP3's as ringtones and have access to the Wi-Fi that AT&T so graciously locked.
