The new custom release adds support to a total of 40 Android devices. The Release Candidate versions are the most stable builds and can be installed for daily use. Additionally, the RC version completely replaces the original stock firmware. It brings unique customised features for the devices.

Galaxy S users, who wish to install Android 4.2.2 on their devices using CM10.1 RC1 build, may follow our step-by-step guide.

IBTimes UK reminds its readers that it will not be held responsible for any mishap. Before installing the custom firmware, users are advised to verify that their handsets meet the following requirements.


1) Install USB Drivers for Samsung Galaxy S to transfer files between the Android device and computer.

2) Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and ensure the USB Debugging Mode is turned on.]

3) As the tutorial is likely to wipe out all data of the phone, create a backup. If the device is having any custom recoveries such as ClockworkMod/TWRP already installed then backup data using the recovery.

4) The Galaxy S should have above 80 per cent of battery charge.

5) The phone should be rooted and have ClockworkMod (CWM) recovery installed.

6) The CM10.1 RC1 build works only on Samsung Galaxy S I9000. As flashing this on any incorrect variant might brick the device, verify the model number of Galaxy S by navigating to Settings>> About phone>> Model number.

7) After flashing the ROM if the device gets stuck on Booting animation or experience boot loop then perform wipe cache partition and wipe dalvik cache five more times and then reboot the device.
