The Samsung Galaxy S 4G can now be installed with the latest Jelly Bean flavor as during the present tutorial I will show you how to apply the CM10 Android 4.2 custom ROM update on your smartphone. It seems that the CM platform is being released to more and more devices lately, though not all the OS upgrades are being official ones. The same can be applied in our case because this CM10 firmware was developed and released for your Samsung Galaxy S 4G by those of xda-developers and not by the CM team.
That’s why you should know that the Android 4.1 Jelly Bean based CM10 software isn’t yet stable, this is the alpha version of the ROM actually. That means there are minor bugs and issues in the system, so don’t expect to receive a fully working OS for your Galaxy S 4G. Anyway, all the bugs will be resolved as soon as a new version of the Jelly Bean update will be launched by the devs, installing the same on your handset being easier than you can imagine. So, if you want to install a customized and optimized Android 4.1 firmware on your SGS4G, then all you need to do is to complete the following step by step guide.
Even though this is being considered a risky and complex operation, you should be relaxed as this tutorial will take you through the installation procedure. In the end your Galaxy S 4G will be safely updated to Jelly Bean with CM10 alpha custom ROM. Due to the fact that you can end up in bricking the device, it is recommended for you to read all the next lines; also make sure that you are performing all the steps that are being listed here. Do not apply things on your phone by yourselves and don’t go straight to the update operation. You must first prepare your SGS4G, so let’s get started.
- A custom ROM firmware, such as CM10, can be flashed only on rooted systems. Therefore, root your Galaxy S 4G or else you will not be able to finish this tutorial.
- By rooting the warranty will get void. This is the most relevant aspect that you must consider before going any further. In case your phone gets damaged, you will be by yourselves.
- As a final tip related to the warranty, you can restore the same. All you need to do is to reset the flash counter and re-install the factory restrictions. That can be done by downgrading to the stock ROM, or by updating with an official software released by Samsung and suitable with your S 4G.
- On a rooted system you will be able to install custom apps that can offer access to the internal system. Such a tool is CWM recovery; the same will be used today, for updating the Galaxy S 4G to CM10 Android 4.1 Jelly Bean, so make sure that your phone is running the mentioned app.
- By using CWM recovery you can make a Nandroid backup for saving the current ROM. If you don’t like the new one, then you can easily restore the stock firmware.
- You will wipe the system of your smartphone meaning that everything that is being saved on your SGS4G will be erased. Therefore, backup the data before starting the update operation (take your time and save everything you need, or else you might regret it afterwards).
- A Windows running computer, your handset and its USB cord will be required.
- For being sure that nothing is interfering with our job, deactivate the security options or programs that are being installed on your PC and on your device.
- If your phone has less than 50% power left it might get turned off in the middle of the process (it will be bricked); charge the battery.
- Enable the USB debugging option on your S 4G.
- And, don’t apply this step by step guide for similar devices with the Samsung Galaxy S 4G smartphone; this version of CM10 will work only for the mentioned handset.
