If you want to improve the Android 4.1.2 Jelly Bean experience on your Galaxy S3 Mini, then you should update your phone to the latest official firmware, the XXAMB3 OS. So, if you need to manually apply the software on your S3 Mini, or if you haven’t receive the OTA release until now, then competing this step by step guide is not an option for you. The present tutorial will take you through the manual installation procedure of the stock Jelly Bean 4.1.2 XXAMB3 ROM, so if you want to flash the same on your Galaxy S3 Mini check and apply the next lines.
The XXAMB3 OS has been officially released by Samsung for the Galaxy S3 Mini I8190 devices, meaning that the firmware can be OTA or by using KIES applied on your phone. Anyway, as you know, when talking about official releases, the OTA are being offered depending on the markets and carriers so not all the S3 Mini handsets will be enjoying the Jelly Bean 4.1.2 improvement on the same time. Because of the same, maybe you will need to manually flash the software on your device, in which case this step by step guide will be perfect for you.
Also, you will have to complete the tutorial if your phone is rooted or powered by a custom ROM firmware. If so, you will not be able to receive and install the OTA release of the Android 4.1.2 XXAMB3 OS, a manual method being required for updating your Samsung Galaxy S3 Mini. Now, don’t worry as you will still apply the same firmware (the OTA one) but by using a manual procedure and not the “over the air” one. Therefore all the features and improvements included in the OTA release will also be installed on your S3 Mini once you perform the present tutorial.
The XXAMB3 OS comes like a minor update, so don’t expect to see major improvements added in the system. Actually the firmware is coming only to resolve some bugs and issues that were reported on the previous version of the Jelly Bean 4.1.2 platform. Anyway, it is still recommended to update your Galaxy S3 Mini with the same for enjoying a more stable Android experience on your phone and also for receiving the latest upgrades available for your phone. Now, if you have decided to complete this step by step guide, then you should start by applying the pre requisites from below.
You need to backup the data which is being saved on the internal storage memory of your smartphone because if something wrong happens you will end up in losing all of your personal saves. So, save the contacts, messages, call logs, market apps and don’t forget the EFS and internet settings. Also, if you have a rooted device you can look forward in making a Nandroid backup too.
You will have to use a Windows running computer where you will download and install Odin. The program will be used on the flashing operation which means that you cannot complete this guide without using the same. And for making things as it should, you first have to uninstall the security programs that are running on your computer and on the Galaxy S3 Mini. Also, it will be a good idea to charge the battery of your handset (especially if there is less than 60% power left) and to enable the USB debugging option on your smartphone (go to “Settings -> Applications -> Development -> USB debugging”).
The best part related to this procedure is that you don’t have to own a rooted device for being able to apply the update operation. You see, we are dealing with the official XXAMB3 Jelly Bean 4.1.2 OS therefore you can flash the firmware without completing other complex operations on your Galaxy S3 Mini. Also, considering that you are flashing the stock ROM, in case you do own a rooted phone, now you will be able to revoke the root access, relock the bootloader and restore the lost warranty.
Do remember though that this method is being suitable only with the Samsung Galaxy S3 model number I8190 so don’t complete this tutorial if you have a similar or different handset; in case you apply the next steps on a different device you will probably end up in bricking the same.
