Update Galaxy S I9000 to Android 4.2 Jelly Bean with AOSP Custom ROM

Even though the Samsung Galaxy S I9000 will no longer receive Android updates due to hardware limitations that doesn’t mean you can’t install a custom ROM update into its system. Furthermore, fortunately for you, a new Android 4.2 powered software has been made available for the Galaxy S devices, the AOSP ROM. Now, this firmware is being based on the latest CM10 stable custom ROM and it is bringing the latest version of the Jelly Bean flavor to your smartphone. So, for learning how to update the SGS I9000 with the same, check the next few lines and complete the present step by step guide.

This is a custom ROM, so the Android 4.2 update has nothing to do with Samsung. Your Galaxy S will have to be upgraded manually and applying the steps from below is all you need. Now, the CM10 based AOSP firmware has been developed by those of xda-developers and according to them, this is a stable variant of the Jelly Bean 4.2 system for your S, though there are still minor bugs into the system. Basically, you will get most of the CM10 features, capabilities and looks and the reported issues will be resolved as soon as a new version of the AOSP software is being provided. Anyway, if you want to learn more about this update, then you can anytime check the source page from here.

In order to safely install the Jelly Bean 4.2 update on your Samsung Galaxy S you must first read the pre requisites. The first aspect to start with is related to the warranty of your phone. You cannot apply this tutorial unless the handset was previously rooted and installed with a custom recovery image like CWM recovery. The root access is a complex operation and by performing the same you will unchain the system of your smartphone. This means that the factory restrictions will be removed, so you will be making important changes on the OS. Furthermore this implies in voiding the warranty.

Well, the warranty will be void, but it can be restored if you will want to. How? quite easily actually. As soon as you decide to downgrade to the stock ROM, the warranty will be regained and the factory restrictions reinstalled. This is happening because the root access will be revoked and the bootloader relocked, so you have nothing to worry about. Then, I have mentioned that a custom recovery image must be flashed on your Galaxy S. That’s true as we will use the tool for the update operation, so you cannot go any further unless you first get and install CWM recovery on your device.

A must have is also a backup procedure. As you will see during the proper steps, a full wipe of the system will be required. Therefore, take your time and save all of your personal info first. As a tip, you can use our backup and restore guides for learning how to save the contacts, the messages, the call logs, the EFS folder, the internet setting and even the current ROM. You can search for suitable guides through our how to section.

Up next, you need to ensure that you can use a Windows running computer, the Galaxy S and its USB cord. Uninstall all the security options and programs from your PC and from your phone as these tools are usually interfering with the update installation process. Enable the USB debugging option on your handset and if the battery status indicates less than 60% power left, charge the battery first, or else the phone might get turned off in the middle of the operation. Don’t forget that this tutorial is being suitable only for the Samsung Galaxy S model number I9000, so don’t try to apply the next steps for similar smartphones because you can end up in bricking them.
