Problem Debranding c905a

[senter]

Okay, so I just got a new c905a from at&t and decided I wanted to debrand it to get wifi and other features. I followed all the steps and they seemed to work but when i tried flashing it with Sony Ericsson Update Service it said my phone was upto date and would not let me flash it. So then I decided to try to flash it with a2uploader, but I accidently flashed it with the wrong region type firmware( i used C905_R1FA035_FS_APAC-ANZ_RED53) and when i tried to start the phone i got a configuration error. So I then tried to flash it with C905_R1BA038_FS_AMERICA_RED53, but i still got the same message when starting the phone. Now I can not do anything with the my phone.

What should I do? Am I still using the wrong firmware?:confused:

Use these files:

C905_R1DA032_MAIN_GENERIC_SI_RED53
C905_R1DA032_FS_AMERICA_RED53
C905_1209-4778_R6A_GENERIC_AMERICA
