I need to revert back to 1.6 or 2.1 stock rom. (i am currently using 2.3.5) I know how to do it but i do not know which file i have to download. I am living in Australia, and my phone is Optus. But there is no Optus so do i choose Australian version???? Or can i just look at the file i used to install fastboot and do i use the same as that????? Link for downloads http://swiftdroidblog.co.cc/forum/showthread.php?tid=4 THANKS IN ADVANCE!!!!
