Odin will be used in that regard, this being the flashing program developed by Samsung and designed especially for update types of procedures.

However, it adds essential bug fixes and stability improvements along with security patches that will fix Samsung’s vulnerabilities that currently exist within the Android core system that powers your Samsung Galaxy A7 2018.

As always, it’s more than recommended to apply the latest official Android update as that’s the only way in which you can end up in using a fully stable Android UI and a smooth Android functionality. And in that respect you can now resume the flashing steps explained below.

Knowing how to manually set up the stock A750FNXXU1ASA4 Android ROM can help you manage different situations and even annoying problems. Since the update operation implies in restoring your Galaxy A7 2018 back to factory state, this tutorial can turn out to be more than helpful when trying to:

  • Go back to stock Android OS when you are using a custom ROM firmware.
  • Regain the lost warranty and re-apply bloatware and built-in settings – the warranty can be void when unofficial operations are being performed.
  • Revoke recently applied tweaks in terms of unrooting the Android system, relocking the bootloader or reinstalling the stock recovery image.
  • Refresh the Android system when it isn’t running as smooth as it used to.
  • Fix different software related problems that can cause malfunctions within the Android core system such as boot loops, lags, hangs, screen freeze errors, battery drain problems, signal strength issues, total blackouts and more.

A backup is recommended even though your personal files should be in safe hands while Odin is running. However, we’re talking about sensible data which might still be needed afterwards. Thus, as a precaution measure saving everything that wasn’t pre-loaded on your smartphone is a good idea. In that regard on your Galaxy A7 start running the built-in cloud storage services or start syncing files with your Google Account; additionally, choose to use an external storage device or use backup and restore apps from Google Play for saving you contacts, call logs, texts, EFS folder, images, videos, audio files, market apps, internet settings or IMEI / NVRAM data.

For being able to perform this tutorial you don’t have to use a rooted device though the flashing steps will work on tweaked handset without problems. Once more, this is an official procedure and Samsung Knox won’t get tripped so from this perspective you have nothing to worry about.

A computer is needed for this operation because there you have to run Odin. Also, on your PC you will have to download the A750FNXXU1ASA4 February 2019 Security Patch which will be then flashed automatically from the flashing program. Since Odin must recognize your Samsung Galaxy A7 2018 (yes, a connection between your devices must be established at some point) on your computer you must first install your phone’s drivers – Samsung KIES might help you get the right drivers that’s available for your handset.

After doing that make sure that your device can be recognized by your computer when that will be required. And you can verify that easily by going to Developer Options; there the USB Debugging feature must be enabled. If Developer Options cannot be accessed from general Settings don’t panic; navigate towards About Phone and there start tapping repeatedly on Built Number and do that until the ‘you are a developer’ message shows up.

As you might know, each time you are about to start a manual operation, you should first verify the power that’s left on your phone. This precaution measure can help you avoid unpleasant situations because sudden shut downs might cause severe malfunctions and can even soft brick the Android core system. In our case, before starting to use Odin for manually installing the A750FNXXU1ASA4 February 2019 Security Patch on your Samsung Galaxy A7 2018 you should plug in the charger if the power that’s left is currently lower than 50%.
