Install CyanogenMod 10 Android 4.1.1 Jelly Bean on Xperia Ray ST18i / ST18a

Xperia Ray ST18i / ST18a users can install Android 4.1.1 Jelly Bean CyanogenMod 10 Custom ROM on their devices. Xperia Ray won’t be getting the official Jelly Bean upgrade for sure as this device has got somewhat old. But that isn’t the end, developer community is there and that’s the only reason I love Android. You can always have the latest iteration of Android running on your device.

This is a Work in Progress ROM and there can be a few bugs, we aren’t aware about them as of now. Your device should be having ClockworkMod Recovery installed because it is required to flash the firmware file on the device.

Make sure that you create a complete data backup before proceeding because if anything goes wrong your device will be completely messed up.
