Unfortunately, it may seem like Samsung has forgotten all about its Galaxy SL users, as there is no ICS or Jelly Bean update released for them and also there are no info about a possible launch of the same. But, you shouldn’t get too disappointed though as thanks to those of xda-developers, you can now update your Galaxy SL I9003 handset to Jelly Bean OS and this by learning how to install the new Codename 3.5.0 custom ROM firmware. This is exactly what we will be checking during the present step by step guide, so if you want to experience the new Android system on your own smartphone, then you are in the right place.
This is not the only ROM available for the Galaxy SL, though it’s the first to bring the Jelly Bean system to its users. The Codename 3.5.0 comes with the latest Android features along with much more as many capabilities will be added to the internal system. So, if you own such a device, then, by flashing the mentioned update, you will be able to improve the battery life, customize the appearances, enjoy the improved web browsing experience, gain more speed and power from your phone and personalize the looks. A new theme and interface will be installed, the classic Android one being replaced. From what we know, the software is working perfectly, so there aren’t bugs or things that aren’t working.
Be aware as this is not an official update provided by Samsung. The Jelly Bean based Codename 3.5.0 ROM was developed by third party devs, meaning that you will have to complete a complex operation which is being considered risky. Also, you cannot use KIES for applying the firmware, a manual procedure being required. Therefore, for ensuring that you are doing all as it should and for ensuring that your Galaxy SL is in safe hands I recommend you to read all the lines from this tutorial, not only the proper steps.
First of all you must backup the data. You should complete this operation each time you decide to perform or change something on your SL I9003. It is the best way in which you can be sure that your personal info is in safe hands. As you will see, for being able to apply the update you will have to make a full wipe of the system first, so all the data which is saved on the internal storage memory will be erased. Because of that the best for you is to backup the text messages, the contacts, the call logs, market apps and even the current ROM. For suitable guides or tips, you can anytime check out our how to section, where you have all the aspects and details needed.
You will not be able to update the Galaxy SL to Jelly Bean Codename 3.5.0 custom ROM unless you first root its system. A root procedure is available here on Android.gs, so don’t hesitate and use the same. Be careful as the warranty will get void and the only way for you to get it back is by downgrading to the stock ROM. Updating to an official software is also a solution but since there is no such thing available, the downgrade operation is the only option left. Beside this, you must also get and flash a custom recovery image (CWM recovery for example) on your phone. The tool is extremely important as without it you cannot install the update.
The other pre requisites are referring to the following: make sure you can use a Windows powered computer; on the PC and on the phone deactivate or uninstall the security tools; enable the USB debugging option from your device by going to “Settings -> Applications -> Development -> USB debugging”; if the battery status shows less than 70% power left then charge the battery; remember to backup, root and install a custom recovery image. Finally, don’t apply the Jelly Bean Codename 3.5.0 ROM on similar handsets with the Samsung Galaxy SL I9003 because you can brick your beloved smartphones.
