  on

The Google Nexus S, with the model number GT-I9020, has recently been added to the list of supported devices for the Release Candidate or RC version of CyanogenMod 10.1 aka CM10.1 custom ROM based on Android 4.2.2 Jelly Bean.

As noted by an Android Jinn report, although the CM10.1 RC1 build is a step towards releasing the final version of CM10.1, it’s more stable than the nightly builds. It also brings more functions and customization, compared to the official release.

The report added that the CM10.1 RC1 custom ROM is still under the development phase and may include bugs and performance-related issues. However, all such problems are expected to be resolved as development progresses.

Here is a tutorial explaining how to install CM10.1 RC1 Android 4.2.2 Jelly Bean on the Google Nexus S GT-I9020. But before trying out the process, users are recommended to take note of the following aspects:

- Backup your data

- Ensure the device has at least 80 percent battery power

- Ensure the USB Driver is installed for Samsung Galaxy S3 in your PC

- Enable USB Debugging via Setting > Developer options > USB Debugging

- Ensure your device is rooted and has ClockWorkMod Recovery installed

 - Do not skip Nandroid backup as it’s very helpful if this custom ROM does not work the way you wanted

- In case you get stuck on boot or experience boot loop, perform wipe cache partition and wipe dalvik cache a few times more before rebooting

Note: IBTimes cannot be held responsible if anything goes wrong. Users should proceed at their own risk.
