How to update Sony Xperia Tipo ST12i to Android 4.1 Jelly Bean

If you have rooted your Sony Xperia Tipo and also installed a custom recovery image on it, it would be a shame if you don’t give the Android 4.1 based Cyanogenmod 10 a try. Cyanogenmod is the most popular 3rd party rom out there, and it is popular for some good reasons. The rom is really customizable and light weight at the same time. Some features like Theme Chooser and customizable power widgets in the notification bar are unique to this rom.

The porting of Cyanogenmod rom to Xperia Tipo has been possible only because of the developmental efforts of FXP at xda-developers.


  • This guide is meant only for Sony Xperia Tipo ST12i. Confirm this by going to Settings > About phone before you start out with this tutorial.
  • We can’t be held responsible for anything wrong that happens with your device. Even the developer is not to blame in case you end up with a bricked device or something like that.
  • If you are unsure about anything, gather some information about it with a quick google search. It can be harmful to do anything that is not within your territory.


  • Your Sony Xperia Tipo needs to be rooted.
  • You also need to have a third party recovery like clockworkmod recovery to flash the rom to your phone. Stock recovery can’t flash unofficial roms and zip files due to obvious reasons.
  • Backup your important apps, data and contacts before flashing this rom. Installing a rom wipes /data as well as /system partition. So you will lose all your apps and messages and contacts and a lot of other data.
  • Make sure USB Debugging is turned on. An option to toggle this setting can be found in Settings > Developer Options.
  • Ensure that your phone is charged well.
