September 2018 Security Patch Released for Samsung Galaxy S7

The new G930FXXS3ERHD firmware is rolled out for the Samsung Galaxy S7 so you should receive the appropriate Android notification anytime now. This is the September 2018 security patch and you can search for it by heading towards Settings – > Software update. If the OTA isn’t there, don’t panic as the roll out will take a while, so maybe you are one of the users who will receive it a little bit later. Also, if you just can’t wait, you can choose to use Odin for manually setting up this new Galaxy S7 update.

The Galaxy S7 official software support is coming to an end which means that most likely your device won’t receive any other major OS improvement – it will be stuck on Android 8.0 Oreo with minor patches pushed out at least until the year ends. In that respect, this G930FXXS3ERHD firmware is nothing but another minor improvement that’s here to address some software-vulnerabilities and security issues that are currently running on the stock UI that runs on your Samsung Galaxy S7.

The September 2018 Security Patch is important because it ensures a fully stable and smooth Android experience. Your Galaxy S7 will still run on Android 8.0 Oreo and no new features will be added, but stability improvements along with bug fixes will be set up. Overall, this update will make things run while you can be sure that your personal data and your online profile is always secured.

Now, as already pointed out, the OTA might be coming on your device later than for other Galaxy S7 users. In that case you have two solutions: still waiting for your Android notification or downloading the full G930FXXS3ERHD firmware package and manually installing it via Odin – the second solution will be further detailed during the next guidelines.

A manual update procedure will be required if your smartphone isn’t running on stock Android OS, or if tweaks were previously applied – for example, you can no longer receive OTAs if you gained root access on your Samsung Galaxy S7. Note: the manual update procedure will restore your device back to factory state so in the end you will manage to revoke root access, relock the bootloader, reinstall the stock recovery image and reinstall bloatware. But, you can use the manual update procedure for addressing software related issues including boot loops, lags, hangs, screen freeze, battery drain, heating issues, total blackouts and so on.

Anyway, using Odin for manually installing the September 2018 Security Patch is an easy-to-follow process that can be quickly applied even by a newbie who isn’t used with such flashing operations. Odin is the official flashing program developed by Samsung, so from this perspective you have nothing to worry about: Samsung KNOX won’t get tripped while Odin is being used and you don’t have to use any extra programs such as third party apps or risky tools. Bottom line, you can safely follow the steps explained below as everything will remain safe and secured all the time.

A backup though is recommended if you are thinking in using Odin for manually installing the September 2018 Security Patch on your Samsung Galaxy S7. This is a precaution measure as your data should be secured while Odin is used. However, in rare situations a wipe might be required and then your personal files might get erased.

So, avoid such unpleasant situations by previously initiating a general backup – you can do it without too much hassle by using Samsung’s own cloud storage service. Additionally, you can choose to sync different files with your Google Account or you can just go to Google Play and download dedicated and already tested backup and restore apps. The goal should be to secure the files which weren’t there when you bought your handset: contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, IMEI / NVRAM data, EFS folder and more.

A manual update operation implies in using a computer. There you will need to download the G930FXXS3ERHD firmware package and set up Odin. For things to work properly, your phone’s drivers must be first installed on your computer – and you can do that easily, through the Samsung KIES utility.

On your Galaxy S7 you need to be able to access the Developer Options. This field should be displayed under general Settings. If it isn’t there, go to About Phone and tap repeatedly (for 7 or 10 times) on the Built Number entry – eventually you will be prompted with the ‘you are a developer’ message. Afterwards, access Developer Options and from there check the USB Debugging feature.

Of course, during the flashing operation you will have to use your phone’s USB cable – a connection between your smartphone and your computer will have to be ensured.

Before setting up the September 2018 Security Patch you have to verify the power that’s left on your Galaxy S7. If the power level is lower than 50% plug in the charger. Do that as otherwise you risk in soft-bricking your device: if a sudden shut down happens while the update operation is running different malfunctions can be caused.

You can also damage your phone if you are using this tutorial on a similar or on a different handset than Samsung Galaxy S7. The September 2018 Security Patch, with firmware built number G930FXXS3ERHD, is compatible only with the already mentioned smartphone.

How to Install September 2018 Security Patch on the Samsung Galaxy S7 by using Odin

  1. Power on your computer and prepare the things that we will use afterwards: go to this page and download the September 2018 Security Patch that’s available for your Samsung Galaxy S7 and then go here and download Odin.
  2. Save the update package on desktop; then run the Odin executable file and just follow on-screen prompts in order to set up the flashing program on your computer.
  3. Remember that your phone’s drivers must be already installed on your PC.
  4. Run the flashing program on your computer.
  5. Afterwards, reboot download mode on your Galaxy S7: switch off your phone and then press and hold the Power, Volume Down and Home buttons at the same time.
  6. Connect your phone with your computer with the help of the USB cable – at this point Odin should recognize your device: the ‘added’ message should be displayed and the ID:COM field should be turned yellow or blue.
  7. Note: if the flashing program isn’t recognizing your S7 try to – close Odin, unplug the USB cable, force restart your device, reinstall its drivers on your PC and repeat the flashing process from the beginning.
  8. On the flashing program click on the AP button and afterwards choose the September 2018 Security Patch package from desktop.

Things that can go wrong and troubleshooting solutions to apply

The most common issues that might happen are related with the flashing program – it might get stuck right in the middle of the update process. Well, if that happens, don’t worry as it’s not the end of the world and your device can still run without problems. However, you have to follow: close Odin on your computer along with its associated processes (the easiest way in which you can do that is by using Task Manager: press the Ctrl+Alt+Del keyboard hotkeys); then, disconnect your smartphone from your computer; also force-restart your Samsung Galaxy S7; reinstall your phone’s drivers on your computer; and in the end repeat the flashing steps that were described and detailed above.

Another thing that can go wrong is related with the last reboot that must be completed. It will take longer than a regular reboot, but in the end you should be able to use the new OS on your device without problems. However, a boot loop might happen while this reboot is completed. And, in that case you have to follow: enter recovery mode on your Samsung Galaxy S7 (press and hold the Power, Volume Up and Home buttons together until the recovery mode menu shows up); in recovery choose to make a hard reset and to clear app data cache – select ‘wipe data factory reset’ followed by ‘wipe cache partition’ and by ‘wipe dalvik cache’; when done, return to main menu of recovery and pick ‘reboot system now’. Everything should run without problems now.

If other software related issues are experienced you can try to fix them by using the Android Safe Mode or by downgrading your device to a previous version of Android OS (also by using Odin, just as showed above).

Final thoughts
