Install February 2018 Security Patch (A520FXXU4BRB1) on Samsung Galaxy A5 2017

If you missed the January 2018 security patch on your Galaxy A5 don’t panic; a new OTA was released for your device and will update the stock Android software to firmware built number A520FXXU4BRB1. As you can already tell, this new update is the February 2018 security patch which is here to smooth up your Android experience. Now, if you want to manually install this OS improvement on your Samsung Galaxy A5 2017, don’t hesitate and follow all the lines that are explained below.

The February 2018 Security Patch is released by Samsung and is designed to fix Samsung’s own vulnerabilities along other problems that might mess the overall Android experience. So, with the A520FXXU4BRB1 firmware installed, your Samsung Galaxy A5 2017 will run better, faster and on an upgraded battery life. Moreover, you will use a secured system that’s fully stable and which smoothly performs in various situations regardless of the processes you choose to initiate.

As already pointed out, this February Security patch is OTA available. It should therefore be automatically received on your phone if the stock Android OS is already running and if tweaks weren’t applied – otherwise you cannot receive the Android notification situation during which a manual process will be required. The OTA is pushed out gradually, or in phases, so not all the Galaxy A5 users will receive the A520FXXU4BRB1 platform at the same time – that’s why, you should have patience.

Anyway, if you want to (or have to) use a manual update operation instead, now you can do so as the full firmware package can be downloaded. So, you can now flash the February 2018 Security Patch through Odin on your Samsung Galaxy A5 2017. The installation process is explained below and, as you will see, can be easily performed even if you are on your first manual update initiative.

Completing the steps from this tutorial isn’t coming with risks – you will be using the official Android update that’s released by Samsung so Samsung KNOX won’t get tripped. Shortly, you won’t lose your phone’s warranty and you won’t have to use complex or risky programs – in that respect, Odin is an official program developed and offered by Samsung and used especially for update types of operation.

A backup is not necessarily needed but it can save you from unpleasant situations – in rare cases your Samsung Galaxy A5 2017 data might get corrupted or wiped out during the update process (we will discuss about these situations a little bit later). Anyhow, you should first save your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, the EFS folder, IMEI / NVRAM data and similar other personal files. There are Samsung’s built-in cloud storage platforms that can help you secure your data but you can also choose to sync your files with your Google Account or use dedicated (and already tested) backup and restore apps from Google Play.

Now, for this process you will need to use a computer – there you will have to install the Galaxy A5 drivers first (Samsung KIES can help you complete this task). Also, your smartphone and its USB cable are required too.

On your phone, before starting the February 2018 Security path update process, you have to enable Developer Options. You can do it by tapping repeatedly on Built Number (accessed from About Phone) – just tap on this field until you receive the ‘you are a developer’ message. Good; afterwards, go to Menu – > Settings and access the Developer Options menu. From there check the USB Debugging field.

You have to be sure that there is enough power left on your handset as otherwise it can get turned off in the middle of the flashing procedure – if that happens, you can end up in experiencing software related problems on your phone (such as bugs, lags, screen freeze, force close errors, battery drain, heating issues, signal strength errors, total blackouts and so on). Therefore, check the power that’s left and if it is lower than 50%, choose to plug in the charger before doing anything else.

Keep in mind that the A520FXXU4BRB1 firmware package discussed during this tutorial is compatible only with the Samsung Galaxy A5 2017 so try not to mess things up.

How to Install February 2018 Security Patch (A520FXXU4BRB1) on Samsung Galaxy A5 2017

  1. Power on your smartphone and switch on your computer.
  2. From here download Odin. Save the file on desktop and then follow on-screen prompts for installing the flashing program on your PC.

  6. Finally, connect your handset with your computer with the help of the USB cable.
  7. Odin should display the ‘added’ message and the ID:COM should be turned yellow or blue; if not, it means the flashing program is having problems in detecting your A5 – so, remove the USB cable, close Odin, reinstall the drivers and then repeat the steps from above.
  8. Next, on Odin click on the AP button and then load the update package from your computer.
  9. When asked make sure that Re Partition and Auto Reboot options aren’t selected.

Problems that can be experienced and how to fix them

Odin gets stuck

Yes, it rare situations the flashing program might get stuck right in the middle of the update operation. So, if that occurs, don’t panic and follow: close the program (through Task Manager if you cannot do it otherwise), unplug the USB cable, force restart your Galaxy A5, reinstall your phone’s drivers on your computer and repeat the steps explained above from the beginning.

Your smartphone gets stuck in a boot loop

As explained, after using Odin you need to initiate one last reboot. Well, this reboot should take longer than a normal reboot but that doesn’t mean you phone should enter into a boot loop. If that happens, you will need to make a hard reset and clear app data cache in order to fix everything. So, reach recovery mode on your Samsung Galaxy A5 – press and hold the Power, Volume Up and Home buttons at the same time, for a few moments; then, from main menu of recovery mode choose the following options ‘wipe data factory reset’ followed by ‘wipe cache partition’.

Final thoughts

Good job; the new February 2018 Security Patch is now running on your Samsung Galaxy A5 2017. Go ahead and test the new functionality – don’t have high expectations as this is a minor OS improvement that doesn’t come with new features, apps or capabilities but with bug fixes and stability improvements. Enjoy and stay close for further update opportunities available for your Samsung Galaxy A5.
