Samsung just detailed the March 2018 security patch and now the Galaxy A8 is the first smartphone to receive this new OTA. The A530FXXU2ARB9 firmware is therefore currently available and should be received during the following days (possible weeks as the OTA is pushed out gradually) on all the Galaxy A8 devices with model number A530F.

Now, if you are tired of waiting for your own Android notification, or if you know for sure that the OTA cannot be received on your smartphone (because tweaks were recently applied) you can now choose to resume the guidelines from below. There, we will see how to manually install the A530FXXU2ARB9 full firmware package on your own Samsung Galaxy A8 2018.

By using the full A530FXXU2ARB9 firmware file you can successfully resume the update process even if your smartphone is currently rooted or tweaked in any other way – as you might know, when tweaks are applied, OTAs cannot be received. Additionally, the steps from below can be performed on an unlocked bootloader, or if a custom recovery image is used. However, in the end, all these tweaks will be revoked because your Galaxy A8 will be restored back to its default state – root will be lost, the bootloader will be relocked, the stock recovery reinstalled and factory restrictions re-applied.

Shortly, everything will be restored as it was in the first day you bought your phone. From this perspective this particular update process can be used if you are currently dealing with software related issues on your phone. Basically, by installing the March security patch you can fix problems such as boot loops, lags, bugs, hangs, screen freeze, battery drain, heating issues, signal strength problems or total blackouts.

And to conclude these aspects, applying the steps from below can be done without assuming any risks. Samsung KNOX won’t get tripped as you are going to use the official Android update and not a custom ROM. So, the Galaxy A8 warranty won’t get lost and you won’t risk in losing access to default apps.

As for the actual March 2018 Security Patch you need to know that you will be dealing with a minor update. This firmware is bringing stability improvements, bug fixes and security patches. Overall, with the A530FXXU2ARB9 software installed your Samsung Galaxy A8 should run better and faster as you will be experiencing a fully stable and smooth OS – of course, your personal data along with your own profile will be protected all the time.

Odin will be the flashing program that will be used in this case. This program is developed by Samsung and used especially on update types of operations. So, you won’t have to use third party apps or other risky programs in order to complete this particular update procedure.

However, your data must be saved first as in rare situations a wipe might be required in the end (we will discuss about these problems a little bit later). For now you need to know that a backup is recommended. Thus, on your Galaxy A8 you should start using Samsung’s own cloud storage services in order to save everything that means something for you. Another way in which you can secure your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, EFS folder, IMEI / NVRAM data and so on is by syncing everything with your Google Account, or by using dedicated backup and restore apps from Google Play.

And since is a manual update procedure, for being able to apply all the steps from below you will have to:

  • Make sure that a computer or a notebook is at your disposal.
  • Your Galaxy A8 and its USB cable are near this computer.
  • On the computer that will be used your phone’s drivers are installed – Samsung KIES can be used in that respect.
  • On your phone you need to be able to access Developer Options from Settings; if you cannot, first go to About Phone and from there tap repeatedly on the Built Number field. After 7 or 10 taps you should see the ‘you are a developer’ message.
  • On your handset, from the recently enabled Developer Options field (located within Menu - > Settings) you need to check the USB Debugging feature.
  • Charge your smartphone before installing the March 2018 security patch – complete this additional operation if the power left is currently lower than 50%.
  • Apply the steps from below only if you own the Samsung Galaxy A8 – the A530FXXU2ARB9 March security patch is compatible only with this particular Android based device.

How to Manually Install March 2018 Security Patch on Samsung Galaxy A8

  1. Open your computer; there install Odin – from here download the program and then follow on-screen prompts in order to set it up.
  2. Then, access this page and download the March 2018 Security Patch for your device.
  3. Save the A530FXXU2ARB9 firmware on desktop and then run Odin.
  4. Switch off your phone, wait a few moments and then reboot into download mode: press and hold Power, Volume Down and Bixby buttons at the same time, for a few moments.
  5. Connect your Galaxy A8 with your computer via USB cable.
  6. At this moment on Odin you should observe: the ‘added’ message displayed and the ID:COM field turned yellow or blue; if not, you have to reinstall your phone’s drivers before retrying.
  7. On the flashing program click on the AP section and just load the Android update package from desktop.
  8. When asked, don’t check the Re Partition and Auto Reboot options; just click on Start.
  9. The update operation will be now automatically completed – when it’s done the ‘pass’ message will show up and the ID:COM field will turn green.
  10. Close Odin and remove the USB cable; you need to reboot your handset in the end.

Problems that might occur and how to solve them

The most common problem is related with the flashing program. In that respect, you might notice that Odin can get stuck in the middle of the update procedure. Well, if that happens, you need to close Odin (you can end the program from Task Manager if you cannot do it otherwise) and unplug the USB cord. Then, you must reinstall the phone’s drivers on your computer and reload the flashing program. Finally, you need to force restart your Galaxy A8 and retry to apply all the steps from above.

Another issue that can be experienced is a boot loop. That can happen during the last reboot. By the way, that reboot will take longer than a regular one. In rare situations, during this particular reboot a boot loop can be caused. In order to address this malfunction you will have to initiate a hard reset and clear app data cache – go to recovery mode (press and hold Power, Volume Up and Bixby buttons, at the same time, for a few moments) and from there choose the following options: ‘wipe data factory reset’ followed by ‘wipe dalvik cache’; when done, return to main menu of recovery and pick ‘reboot system now’.


So, that’s all. The March 2018 security patch is running on your Samsung Galaxy A8.
