Do you want to use the latest Android UI on your Samsung Galaxy A3 2017? If you do, then you need to learn that anew OTA is available for your smartphone as Samsung just released the July 2018 Security Patch. This software will bring the stock build number to A320FLXXU2CRG2 and will smooth up the Android experience on your A3. Anyhow, the best is that you can now manually flash the same firmware by using Odin, this being the process that will be detailed during the following guidelines.

Therefore, Odin can be used for applying the July 2018 Security Patch on the Samsung Galaxy A3 2017. And that’s possible because the full firmware package can be anytime downloaded from online sources. Thus, instead of using and flashing the OTA package you can now manually set up the latest Android OS that’s available for your handset.

And that’s great especially if you use a tweaked device – then, new official updates can be only manually installed. Also, using a manual procedure is recommended if the OTA isn’t released on your market or if you want to speed things up a little bit – usually the OTAs are offered gradually so some users might receive their Android notification sooner than others.

However, by manually flashing the July 2018 Security Patch you will also manage to restore your Samsung Galaxy A3 2017 back to its factory state. Thus, tweaks will be revoked – you will revoke root access, relock the bootloader, reinstall the stock recovery image, re-flash bloatware and so on. Due to same reasons, this update procedure can help you fix common Android software related problems such as boot loops, lags, hangs, screen freeze, battery drain, heating problems, signal strength issues, total blackouts and more.

As for the actual July 2018 Security Patch you need to know that you aren’t dealing with a major OS improvement. This is a small update that’s here to secure your Android experience. Also, the patch will bring bug fixes and several stability improvements so that you can enjoy a fully stable and smooth UI all the time.

Now, before starting this manual update procedure consider in saving your personal data, info, accounts and files. Don’t panic, you shouldn’t lose anything while Odin is used, but in rare situations your data might get corrupted. So, for avoiding such unpleasant situations, a general backup is recommended at this point. You can save almost everything easily by using built-in cloud storage platforms, by syncing apps with your Google Account or by using dedicated and already tested backup and restore apps that are available on Google Play. While you save stuffs don’t forget to secure your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and other files that might be still required afterwards.

This update operation is official. Samsung KNOX won’t get tripped so you won’t risk in losing your Galaxy A3 warranty while manually installing the July 2018 Security Patch. Odin is an official program developed by Samsung so you won’t have to use risky program either – from this perspective you really have nothing to worry about.

A computer must be at your disposal. Your smartphone will be required too. Now, on the PC you will have to set up Odin so first, make sure you install your Galaxy A3 drivers as otherwise the flashing program won’t run properly – you can get the right drivers by using the Samsung KIES toolkit.

On your phone the USB Debugging option must be enabled – you can do that by accessing Developer Options under Menu - > Settings. Note: if Developer Options cannot be accessed, you will have to go to About Device from where you have to tap repeatedly on Built Number – tap on that field for about 7 or 10 times until the ‘you are a developer’ message is displayed.

Charge your Samsung Galaxy A3 2017 before flashing the July 2018 Security Patch if the power that’s left on your phone is lower than 50%. If the power is lower than that value your device might get switched off in the middle of the update process; in that case malfunctions can be caused on your handset and you can end up in soft bricking its Android system.

How to Install July 2018 Security Patch A320FLXXU2CRG2 on Samsung Galaxy A3 2017

  2. Download the July 2018 Security Patch for your Galaxy A3 2017 – get the package from here and save it on desktop.
  3. On your computer run Odin.
  4. Power off your phone and afterwards enter its system into download mode: press and hold the Power, Volume Down and Home buttons for a few moments.
  5. Then, connect your handset with your computer – just plug in the USB cable.
  6. Make sure that Odin is recognizing your phone: on the flashing program the ‘added’ message must be displayed and the ID:COM field must be turned yellow or blue; if not, reinstall the drivers for your phone on your computer and retry.
  7. On Odin click on the AP button and select the update file from desktop.
  8. Then, click on Start and wait while the July 2018 Security Patch is being applied – on your way make sure that the Re Partition and Auto Reboot options aren’t selected.
  9. When everything is done on Odin you will receive the ‘pass’ message and the ID:COM field will turn green.
  10. Close Odin, remove the USB cable and reboot your Galaxy A3 2017 as that was all.

While trying to complete the steps explained above, you can deal with unexpected problems; well, here is how you can fix the most common issues:

If Odin gets stuck while the update operation is running you will have to: close the flashing program; end Odin’s related processes from Task Manager (press and hold the Ctrl+Alt+Del keyboard hotkeys); disconnect your smartphone from your computer; force restart your Samsung Galaxy A3 2017; reinstall your phone’s drivers on your computer; repeat the flashing steps from the beginning as this time everything should run as expected.

The last reboot recommended during the last update step will take a longer time than you are used to. However, a boot loop shouldn’t happen during this long-lasting reboot. If, however, your Galaxy A3 gets stuck in a boot loop you will have to make a hard reset and clear app data cache for fixing the problem and here is how you can do that: go to recovery mode (press and hold the Power, Volume Down and Home buttons together, for a few moments) and from recovery select the following options – ‘wipe data factory reset’ followed by ‘wipe cache partition’; when done, return to main menu of recovery and pick ‘reboot system now’.
