The December Security patch is officially available for the Samsung Galaxy J3 2017. So, if you want to fix the Android vulnerability issues and to add new bug fixes and security add-ons, don’t hesitate and complete this guide. The lines explained below will help you apply the Android 7.0 Nougat firmware manually as we are going to check how to flash the full software package and not the OTA build – I will tell you why in just a few moments.
Thus, the December Security patch is OTA available which means you should soon receive the update notification right on your Samsung Galaxy J3. However, the OTA is currently being pushed out gradually so some users will receive it sooner than others. Additionally, the OTA can be spotted, received and applied only if on your phone the stock Android OS is already running and only if tweaks weren’t applied.
Bottom line, you won’t be able to install this new update if root access is ensured or if you flashed a custom ROM platform. In those situations you will have to follow a manual update operation that uses the full firmware package and which can be performed through Odin (Odin is an official tool developed and offered by your OEM). Of course, in these situations your device will be restored back to its initial state.
That’s why the steps from below can be also used as a general troubleshoot solution through which you can try to fix the most common Android soft related issues. But, you will also manage to revoke root access, relock the bootloader, reinstall the stock recovery and re-apply the bloatware and other security restrictions.
The warranty of your Samsung Galaxy J3 2017 won’t get void while you install the December security patch because you are going to use the official Android 7.0 Nougat software – so, Samsung KNOX won’t get tripped. From this perspective you have nothing to worry about as you won’t have to use complex or risky programs – as already pointed out, Odin is the only program that will be required.
However, a general backup should be considered. Only in rare situations you can end up in losing your data while manually installing an official update. But, since the risk is possible, you should be precautious. So, sync your files with your Google Account, use built-in cloud storage platforms or use backup and restore apps from Google Play and secure everything that wasn’t there from day one – along with your personal data, info, accounts and files you should also take care of internet settings, EFS folder or IMEI / NVRAM data.
You should install Odin on a Windows based computer so make sure you can use such a device. On the same computer the Samsung Galaxy J3 drivers must be installed – you can get and apply the drivers by using the Samsung KIES utility.
Your smartphone and its USB cable are also required. Since a connection between your phone and your computer will have to be established, first you need to: enable Developer rights by tapping repeatedly, for 7 or 10 times, on Built Number (just until you notice the ‘you are a developer’ message displayed) and check the USB Debugging field located under Developer Options (hint: Developer Options can be accessed from general Settings).
An important aspect: the power that’s left on your Galaxy J3 must be higher than 50%. The update operation will drain the juice out of your phone’s system so the there is a small risk: if your device will get switched off while you use Odin for installing the December Security patch the Android OS might get soft bricked. Therefore, I strongly recommend you to charge your smartphone if that’s required.
The Android 7.0 Nougat firmware package offered below is compatible with the Samsung Galaxy J3 2017. Don’t use this tutorial if you own any other similar Android based device as you can mess things up.
How to Manually Update Samsung Galaxy J3 2017 with December Security Patch
- First, download the update package – you can get this file from this page.
- Download Odin and don’t forget to install the drivers for your smartphone on your computer.
- Now, save the Android update file on desktop and on the same location install Odin by following on-screen prompts.
- When done, run the flashing program on your computer.
- In the meanwhile, power off your Android device and wait a few moments until this process is completed.
- Next, reboot download mode on your Samsung Galaxy J3 – press and hold the Power, Volume Down and Home buttons at the same time, for a few seconds and afterwards connect your handset with your computer via USB cable.
- Odin will have to recognize your device – the ‘added’ message must be displayed and the ID:COM field must be turned yellow or blue. If not, reinstall your phone’s drivers on your computer and repeat.
- Click on PA option and pick up the Android 7.0 Nougat update package on Odin.
- When asked, don’t select the ‘Re partition’ and ‘Auto reboot’ features.
- Click on Start and wait while the installation process is completed.
- You can close Odin, remove the USB cable and reboot your smartphone when you will receive the ‘pass’ message and when the ID:COM field will be turned green.
Note: Odin can get stuck right in the middle of your update operation; in that situation you will have to close the program, unplug the USB cord, force-restart your smartphone and repeat the steps explained above.
Note 2: during the last reboot, in rare situations a boot loop might be issued on your Galaxy J3 2017. You can fix this malfunction by entering recovery mode (press and hold Power, Volume Up and Home buttons at the same time, for a few seconds); from recovery you then have to clear app data cache and make a hard reset – you can initiate these processes by selecting ‘wipe data factory reset’ and ‘wipe cache partition’.
