Even though there won’t be any further Android 4.2.2 Jelly Bean OTA updates released by Samsung for its Galaxy S I9000 smartphones, there will always be custom firmwares available for the mentioned device. The Galaxy S is still a highly appreciated handsets and this even though its performances are quite out dated. Anyway, the best is that the latest version of CM10.1 has been developed for the Samsung Galaxy S I9000, so today we will be checking on how to flash the new RC5 build of CM10.1 (based on Jelly Bean 4.2.2 OS) on your phone.

The custom ROM is still in development stage though, so there might be some things that aren’t working properly. The bugs are minor and soon the CM team will resolve the same and update you with a stable variant of the RC5 firmware. Therefore, I recommend you to flash this software in order to test the new CM10.1 platform on your Galaxy S; of course do make a Nandroid backup first as if you won’t like the system, then you will be able to restore the stock JB firmware. Do check the rest of the lines from this step by step guide for applying everything properly.

Despite the mentioned aspects, this is the latest release of CM10.1; the firmware is based on Android 4.2.2 Jelly Bean OS, so the same will be installed on your Samsung Galaxy S device. The software is coming with new and useful features, apps and capabilities therefore by completing this tutorial you will be able to improve the performances of your phone and also upgrade its Android user experience. In a few words, your handset will be installed with a custom variant of Jelly Bean that can be customized and optimized by your own taste; furthermore, once the firmware is flashed, you will notice that battery life has been improved, the system upgraded and the speeds increased.

If you had decided to update your Galaxy S with the new CM10.1 RC5 JB 4.2.2 custom ROM, then first of all unsure that your smartphone is rooted and installed with a custom recovery image. The firmware can be applied only on a rooted system and only by using a custom recovery tool, like CWM recovery. So, do perform these operations before going any further – be careful though as the warranty will get void; if something bad happens you will be by yourselves (we shouldn’t be held responsible). Note: the warranty can be regained if you downgrade your Samsung Galaxy S to stock Android OS, or if you un-root its system.

Before, I have mentioned something about a Nandroid backup. Well, learn how to complete this operation because if you will not like the CM10.1 RC5 software, or if you will need to go back to the stock ROM, then a Nandroid backup will be more than necessarily – by using the recovery mode you can easily save / restore the current ROM.

Furthermore, do consider in saving all of your personal settings, data and info along with the current Android firmware. You see, a wipe will be required and without making a full backup, you will probably end up in losing everything that’s saved on your phone’s internal storage memory (EFS folder and internet settings included).

Finally, just before starting the update operation do read and apply: a computer or notebook is being required so ensure that you have access to the same; your Galaxy S and its USB cable should also be near you; on both computer and smartphone you must deactivate the antivirus, antimalware and Firewall protection because the security programs might interfere with the flashing process; enable the USB debugging option on your phone – go to “Settings -> Applications -> Development -> USB debugging”; charge the battery of your handset, or else it might get turned off while you will try to apply the Jelly Bean 4.2.2 based CM10.1 RC5 custom ROM; remember that this guide is compatible only with the Samsung Galaxy S model number I9000.
