CyanogenMod 10 ROM Jelly Bean 4.1 Upgrade for Samsung Galaxy S3


After waiting for a while, the Android Jelly Bean based CyanogenMod 10 ROM is now available for Samsung Galaxy S3. If you are having an international variant of Galaxy S3, then you can upgrade to this ROM. CyanogenMod 10 has been preferred over others ROM because they provide jellybean users with a better interface and performance. It provides better keyboard support along with advanced voice navigation. However, it is yet an early upgrade of CyanogenMod 10 for Samsung Galaxy S3 so there have been many bugs reported at the developers page.

Following are the features which were found not working properly:

  • FM Radio was nonfunctional.
  • Camera is working but it was too unstable to be used.
  • Some user even reported that Wi-Fi tethering is not working.
  • No Camera icon available in App drawer.


Important Note: Although, we have taken the ROM link from a very reliable developer(XDA-Forum), yet go for this upgrade at your own risk as neither this site nor the author would be responsible for any problem in upgradation. However, this happens rarely. Also you would lose warranty of the hardware(if any).

The upgradation Process has been divided into two parts:
