Hello, I need a urgent help in restoring my X10i to 2.3.3. Yesterday unfortunately I copied the build.prop of LT18i (Xperia Arc S having ICS 4.0.4) to my device (X10i) and all was fine till the phone was rebooted. Now X10i when booted, just shows Sony Ericsson and then no display on screen. Through Android commander I can see the files under system folder (build.prop) but just because it's not rooted, I cannot replace the build.prop with the original one (which I had backed up). Can anyone help me to replace the build.prop file to get my phone working? Your urgent help in this regard is highly appreciated. Thanks in advance.
