• Download these file : CM10 KERNEL (mirror), the ROM, GoogleApp, ADDON PACK

Steps to install the Android 4.2.1 on your Xperia X10i:

• First thing first make sure your smartphone is charged more than 50%.
• Copy the ROM, Gapp and addon pack to a microSD card and insert it into your Xperia.
• Now install flashtool then, copy the "X10_4.1.X_cmx10_BootManager_v21.ftf" file to "C:\Flashtool\firmwares" then run flashtool (clear that folder before coping the ftf file for security reasons).
• On flashtool click on "flash" then select flashmode and OK, chose the CM10 ftf kerne and follow the instruction.
• Now after the flash finish, shutdown your Xperia X10, then boot to the recovery, after you power on the smartphone, when the first logo appear press the back button repeatedly (don't hold it) until the recovery menu appear.
•  Now wipe/reset, then chose install zip from sdcard and install the ROM, then the Gapp.
• Don't install Addon now, just reboot the phone and wait until it startup.
• After that you can go back to the recovery and install the addon which will add the nice Xperia Z theme to your X10i, in addition to many useful features.
