Samsung Galaxy Express

If you have a Galaxy Express, then update to the Official Jelly Bean 4.1.2 should be on your to-do list. Even if the device has a great plus when it comes to design, as it is quite similar to the Galaxy S3 one, the problem comes when we talk about its platform. It has a ICS platform, not a Jelly Bean one, so in case you have such a device you would like for sure to update to the OS.

The following step-by-step guide will help you update the  XWAMC4 ROM, as the official Android 4.1.2 firmware has been released. It gives you 2 possibilities of updating either via OTA or using the KIES from the Galaxy Express.  So, if you follow our article, you will be able to manually flash the software, as you will be provided each step in order to have a successful operation. You should know that the OTA and KIES are available only for the locked devices.

Now you can proceed to applying the official Android 4.1.2 Jelly Bean, dubbed as XWAMC4, on your Samsung Galaxy Express, using a manual method. You should know though that the you should apply the stock Jelly Bean software using a manual operation.

You should also know that if your Samsung Express is rooted with Jelly Bean 4.1.2 OS, then it won’t be OTA received, so if your device is rooted you will see at the end of the process that the root access will be revoked. If you ask why, then you should be aware that all the factory restrictions and default settings will be re-installed on the internal system of the device, but what is great is that you will be able to benefit of warranty again, even if it was void at a previous operation (such as root access or custom ROM firmware). So, enjoy great features and apps on your Galaxy Express right after 15 easy steps.

In order to be able to follow the proper steps while you update your Samsung Galaxy Express to the official Jelly Bean 4.1.2 XWAMC4, you will need extra tools, such as ODIN. Odin is a tool that will help you root and/ or flash your device; you will see that it is an easy to be used tool and its installation requires about 5 minutes, maximum.

Also, you need a computer or notebook which is running Windows, as the Odin and the other tools require this operating process.

Ok, ensure that you have all the above and we can now proceed to the pre requisites. First and maybe the most important is that you should backup all the data you have on your Samsung Galaxy Express.

You might lose your personal data while you update to the Official Jelly Bean, so we kindly recommend you to save it, starting with the messages, call logs, contacts and don’t forget about the EFS folder and market apps. In order to be sure, you could also perform a Nandroid backup for the current ROM, but this can only be applied to the rooted devices.

If you don’t follow the steps correctly or the device will have any problem during the operation, the internal system might be broken and then you will lose all of your personal data. So, our recommendation is not to skip the backup operation.

So, before we start be sure you have everything you need: a computer, the Samsung Galaxy Express you want to update the Jelly Bean on and, last but not least, a USB cable.

Don’t forget that all the security programs should be deactivated from both the computer and the Samsung Galaxy as the programs can cause problems during the flashing process. By security programs we understand the antivirus, Firewall and any other problem you might have installed.

Also, be sure you have the battery is more than 60% charged otherwise your phone might turn off while you install the Jelly Bean XWAMC4 firmware and if this happens you have to start the operation all over again.

Before you proceed, be sure the USB debugging option is enabled on your device. You can do this by following this path: Go to Settings, Applications and then choose Development and USB debugging.

Now if you have followed all the above, you can continue to the actual step-by-step tutorial. You should know that these steps are compatible only for the  Samsung Galaxy Express model number I8730, so don’t do this operation on any other handset. You might risk to brick your device if so.
