Install Official Android 8.0 Oreo on Galaxy Tab S3 SM-T820 using Odin

As Samsung is trying to cover as much as possible in term of Android 8.0 official roll outs, a new firmware was just made available. This time we’re not talking about a new smartphone that’s ready to receive the latest Android built, but about the Galaxy Tab S3, Samsung’s high-end tablet that was officially released last year with Android 7.0 Nougat out of the box. Thus, starting from today you can apply the latest Android 8.0 Oreo software on your Tab S3 – the update is currently pushed out for both Wi-Fi and LTE models (SM-T820 and SM-T825).

The software is released in form of a new OTA that will be received on the Samsung Galaxy Tab S3 only if you follow the on-screen prompts indicated by the Android notification system – as always, when a new OTA is released on your device you receive automatic notifications that will then guide you through the actual flashing operation. However, these roll outs are usually offered gradually and for limited markets only. Furthermore, an OTA can be received and applied on if your handset is already running on stock Android OS and only if everything is on factory state – shortly, if tweaks were applied you cannot receive and install the Android 8.0 Oreo OTA.

Therefore, some Samsung Galaxy Tab S3 (SM-T820 and SM-T825) users might receive the Oreo OTA sooner than others, while in some cases the notification will not be embraced at all. That’s why, a good idea will be to learn how to install this update manually. A manual update process can help you skip this common ‘OTA wait’ and can help you apply the latest official Android firmware even when tweaks were applied – a manual flashing process will install the Oreo OS even if your tablet is currently rooted, running on an unlocked bootloaoder, powered by a custom ROM or installed with a custom recovery image.

Of course, for being able to do such thing, you must use the full firmware package. Don’t worry, the manual flashing procedure is still an official process, quite similar with the OTA one. However, in our case Odin will be used, which is the official flashing program developed by Samsung and usually used during Android update procedures. Thus, Samsung KNOX won’t get tripped if you choose to follow and apply the steps from below; also, you won’t lose access to built-in apps and you won’t have to use risky or third party platforms for completing the steps available below.

Now, you can use this tutorial for updating your Galaxy Tab S3 or for restoring your tablet back to its factory state. Shortly, this flashing operation can help you revoke recently applied tweaks and can help you fix different software related issues such as boot loops, lags, hangs, screen freeze errors, battery drain, heating problems, signal strength issues, total blackouts and so much more. And, of course, in the end you will be able to use a fully stable and smooth Android 8.0 Oreo system – this update is coming with the latest features available for your tablet, with different bug fixes and stability improvements and with the latest security patches.

While using Odin is unlikely to experience problems. However, in extremely rare situations your data might get corrupted or a wipe might be required (we will discuss about such situations a little bit later). So, since a small risk is still there, you shouldn’t update your Samsung Galaxy Tab S3 to Android 8.0 Oreo firmware without making a backup first. Therefore, consider in securing your images, videos, audio files, market apps, internet settings, EFS folder, calendar info, contacts, texts, IMEI / NVRAM data and everything else that isn’t there from day one. Do note that a general backup can be easily handled as you can anytime choose to: sync different files with your own Google account, use already built-in cloud storage services added by Samsung or download compatible backup and restore apps from Google Play (in that case make sure you get already tested tools for avoiding any unpleasant situations).

A computer is needed for this manual update operation. There you must first install the Galaxy Tab S3 drivers, which can be easily done by using the Samsung KIES toolkit. Then, on your PC you will have to set up Odin as explained during the steps from below.

Meanwhile, on your tablet you have to enable Developer Options by tapping repeatedly on Built Number – keep tapping on this field until the ‘you are a developer’ message shows up. Then, on your tablet go to Menu – > Settings – > Developer Options and from there check the USB Debugging option.

Another relevant aspect: verify the power that’s left on your Tab S3 before installing the Android 8.0 Oreo update. In case this power is lower than 50%, plug in the charger first – if the power is low your device can get switched off right while Odin is being used and in such situations you can end up in soft bricking your handset (different malfunctions can be caused).

Of course, keep in mind that, for now, the official Android 8.0 Oreo software is available only for the Samsung Galaxy Tab S3 with model number SM-T820 and SM-T825.

Possible issues that can be experienced and how to fix them

In some situations you can notice that Odin isn’t responding anymore. If that happens you will have to: close Odin (just end its associated processes from Task Manager – press Ctrl+Alt+Del); unplug the USB cord; force restart your Samsung branded tablet; reinstall your Tab S3 drivers on your computer; repeat the steps explained above.

Also, problems might be experienced during the last reboot that must be completed on your tablet. Then, a boot loop might happen, situation during which you must follow: reboot recovery mode on your Android device (press and also hold the Power, Volume Up and Home buttons together for a few seconds); from recovery make a hard reset and clear app data cache – choose ‘wipe data factory reset’ followed by ‘wipe cache partition’; finally, reboot your handset and enjoy.

Good work; now you know how to manually install the Android 8.0 Oreo firmware on your Samsung Galaxy Tab S3. Bookmark this update tutorial because it can help you solve other problems beside the actual update challenge – as already outlined, the flashing process can help you fix software related issues or it can help you revoke root access or other similar tweaks.
