Ok so I'm guesssing I'm supposed to flash it with both at the same time? Or do I flash it with "C905_R1DA032_MAIN_GENERIC_SI_RED53" first and then flash it again with "C905_R1DA032_FS_AMERICA_RED53"
Okay, thank you to everyone. I got everything up and running. I just have one last question though. Can I still use the Sony Ericsson Update Service to update my phone or will I have to flash it with A2uploader whenever an update comes out? (cause I kinda find the firmwares a bit confusing)
