Do you own the SM-G9350 model of the original Samsung Galaxy S7 Edge? If you are, then you should receive a new OTA on your smartphone – yes, that’s right Samsung officially started to roll out the January 2018 Security Patch for your handset. However, since the OTA can be received only in certain conditions and since you might have to wait a while for your own Android notification during the following lines we will show you how to complete the flashing process manually. So, let’s see what it’s all about.
As always, the OTA is offered in phases and for limited markets only – currently it’s available only in China and only for the SM-G9350 version of the Samsung Galaxy S7 Edge. Moreover, the January 2018 Security patch can be received in form of an Android notification only if your device is already running on stock Android OS and only if tweaks weren’t already applied – for example, if root was applied you won’t receive this new Android 7.0 Nougat OTA notification.
So, as you can see, there are situations that will require a manual update procedure, and that’s why you should now check the guidelines that are explained below.
As for this January 2018 Security patch, here is what you need to know, before choosing to do anything else. This a minor Android 7.0 Nougat update released by Samsung for the Galaxy S7 Edge for adding new security patches and for fixing recently reported problems. Mainly, the January 2018 Security patch will bring bug fixes, add-ons for addressing security breaches, different stability improvements and that’s it. You won’t receive new features, apps or capabilities. However, if you want to secure your Android experience and if you want to use a fully stable ROM, you shouldn’t miss this new update.
Now, the manual update procedure can be applied even if you recently tweaked your Galaxy S7 Edge. Shortly, the steps from below will work even if your device is rooted, running on an unlocked bootloader, installed with a custom recovery image or flashed with a custom ROM. But, once the installation process is completed you will notice that root was revoked and everything restored back to default. And that’s not a bad thing as you can take full advantage of this aspect – manually flashing the stock OS can help you fix the most common Android soft related issues like boot loops, lags, hangs, screen freeze, battery drain, heating situations, signal strength problems, total blackouts and so on.
As you can already tell, this is going to be an official operation. The flashing process is supported by your OEM, which is also offering the flashing program – yes, that’s right, Odin will be used for installing the January 2018 Security patch on your Samsung Galaxy S7 Edge. Thus, from this perspective you have nothing to worry about – Samsung KNOX won’t get tripped so you won’t lose your phone’s warranty and you won’t have to use complex or risky tools.
A backup on your Galaxy S7 Edge should be however applied. You see, in rare situations, if things don’t work as expected, a wipe might be required – once again, only in rare situations. However, since the risk is there, you should be careful especially if you have important files saved on your phone – as a general idea it’s recommended to save everything that wasn’t there from day one: contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, the EFS folder, IMEI / NVRAM data and so on.
This backup operation isn’t complex and can be easily and quickly applied. In that respect you can always choose to use one of the cloud storage services that are pre-loaded on your phone; or you can just sync your files with your Google Account; or, of course, you can download and use compatible backup and restore apps that are available on Google Play (in that case make sure you download only already tested platforms).
For this particular update operation a few things must be prepared first:
- A computer as Odin must be downloaded and installed there; your smartphone of course, and its official USB cable are also required.
- On the computer you are using make sure that the Galaxy S7 Edge drivers are installed. If not, you can just use the Samsung KIES toolkit.
- On your phone you have to enable Developer Options. This operation can be applied by tapping repeatedly on Built Number (from Menu – > Settings – > About Phone) – you will receive the ‘you are a developer’ message after tapping for 7 or 10 times on the already mentioned field.
- Also on your phone you need to check the USB Debugging field. And this process can be done through Developer Options: just navigate towards Menu – > Settings – > Developer Options.
- It’s essential to charge your device before starting the January 2018 Security update process if the power that’s left on your S7 Edge is currently lower than 50%.
- A power level lower than that threshold might mean only one thing: your handset can get turned off in the middle of the flashing process, situation during which different malfunctions can be caused.
- Keep in mind that this tutorial is compatible only with the Samsung Galaxy S7 Edge model number SM-G9350. The G9350ZCU2BQL3 January 2018 Security Patch will work only for the already mentioned Android based device so be careful and try not to mess thing up.

- If your handset isn’t recognized, close Odin and unplug the USB cord; then reinstall your phne’s drivers and retry.

Problems that might happen and how to address them
As mentioned already, Odin can get stuck while you try to apply the firmware package. In that situation you will have to follow: close the flashing program and remove the USB cord; force-restart your Samsung Galaxy S7 Edge and reinstall its drivers on your computer; reapply the update procedure from the beginning.
Also, a similar problem might happen during the last reboot. This particular reboot should take a while – longer than a regular one. However, if during this reboot your device gets stuck into a boot loop, follow: reach recovery mode on your Android device; from recovery make a hard reset and clear app data cache – basically, select ‘wipe data factory reset’ followed by ‘wipe cache partition’; return to main menu of recovery and pick ‘reboot system now’.
