Samsung is pushing out the December 2018 security patch for most of its high-end smartphones and tablets, so if you own the Galaxy S9+ you should anytime now receive your own Android notification. But, if you don’t want to wait for the OTA, or if you know that your phone cannot receive the G965FXXS2BRK3 firmware by air, then you can choose to use this step by step guide – the steps explained below will show you how to use Odin for manually setting up the December 2018 Security Patch on your Samsung Galaxy S9+.
The December 2018 Security Patch is, as you might already know, the monthly update released by Samsung, a firmware that’s here to improve your overall Galaxy S9+ Android experience. The G965FXXS2BRK3 software isn’t introducing new features, apps or capabilities but comes with essential bug fixes and stability improvements. Of course, the most important aspect is related with the security patches which will secure your online profile and your off-line identity. Bottom line, with the December 2018 security patch installed your smartphone should run better than it used to.
The manual update operation will help you skip the OTA wait – as we all know the roll out is pushed out gradually and for limited markets only. Also, an OTA can be received only on certain conditions: your smartphone must run on stock Android OS and everything should run without additional tweaks – for example, you won’t be able to receive Android notifications if root was enabled. So, these negative aspects can be avoided if you choose to flash the firmware manually: the steps from below can be used even if your device was already tweaked.
However, during this update operation your Samsung Galaxy S9+ will be restored back to its default state. Shortly, in the end you will manage to revoked root access, relock the bootloader, reinstall the stock recovery image and re-apply bloatware. Additionally, due to same reasons, this tutorial can be used as dedicated troubleshooting solutions: you can address different Android software related problems including boot loops, lags, hangs, screen freeze errors, battery drain, heating problems, signal strength issues, total blackouts and so on.
Good; a backup should be first completed on your Samsung Galaxy S9+. Don’t worry, your personal files should be safe during the December 2018 Security Patch installation process, though in rare situations you can end up in losing certain data. So, just for your own protection, perform a backup for securing everything that’s important for you: contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, EFS folder or IMEI / NVRAM data. As backup and restore solutions you can always choose to: use an external storage device, sync your files with your Google account, download dedicated and already tested backup and restore apps from Google Play or use built-in cloud storage services.
Since we describe a manual update procedure a computer must be at your disposal. On that computer you will save the required files and install Odin. Also, for making things work, on the computer that will be used the Samsung Galaxy S9+ drivers must be installed first.
On your smartphone enable Developer Options – just navigate towards About Phone and there tap repeatedly on Built Number until the ‘you are a developer’ message shows up. Afterwards, go to Settings, access Developer Options and check the USB Debugging feature.
You should make sure that your phone runs on more than 50% power before starting to install the December 2018 security patch; otherwise plug in the charger first. Do that as otherwise a sudden shut down might happen right in the middle of the update process. Unfortunately, a shut down might cause severe problems on your Galaxy S9+ - shortly, if you’re not careful enough you can end up in soft-bricking your handset and its Android system.
How to Manually Install December 2018 Security Patch on Samsung Galaxy S9+
- Download the December 2018 Security patch for your Samsung Galaxy S9+ on your computer and save the update package on desktop – you can get the firmware file from this page.
- Then, download Odin; run the executable file, follow on screen-prompts and set up the flashing program on your PC.
- Don’t forget to set up the right drivers for your phone before doing anything else – in that regard you can use the Samsung KIES toolkit.
- Good; now run Odin on your computer.
- Power off your phone and in the end go to download mode: press and hold the Power, Volume Down and Bixby buttons on your Galaxy S9+.
- Connect your phone with your computer via USB cable.
- Odin must recognize your handset: the ‘added’ message must show up and the ID:COM field must be turned yellow or blue; if not, reinstall your phone’s drivers on your PC and retry.
- On the flashing program click on the AP button and load the December 2018 security patch from desktop.
- Don’t select the Re Partition and Auto Reboot options on Odin and click on Start when ready.
- The update operation will be now automatically completed, so sit back and relax.
- On Odin the ‘pass’ message will be displayed; also the ID:COM field will be now turned green.
- At that point you can successfully close the flashing program, unplug the USB cable and reboot your Android based device.
- That’s all.
Troubleshooting solutions for the problems that might be caused during the update operation
Odin might stop working or it can get stuck right while you try to complete the steps explained above. So, if you end up in experiencing problems with the flashing program follow: close Odin and end its associated processes (you should do that from Task Manager: press and hold the Ctrl+Alt+Del keyboard combination); then, unplug the USB cable and disconnect your phone from your computer; force-restart your Samsung Galaxy S9+; reinstall your phone’s drivers on your computer; repeat the update steps that were already explained above.
The last reboot might end up with a boot loop; that shouldn’t happen even though this particular reboot will take a while (longer than a regular one). Anyway, if a boot loop happens, follow: enter recovery mode on your Samsung Galaxy S9+ (press and hold the Power, Volume Up and Bixby buttons for a few seconds); from recovery initiate a full wipe (make a hard reset and clear app data cache) by selecting ‘wipe data factory reset’ followed by ‘wipe cache partition’; when done go back to main menu of recovery and choose to return to Android mode.
