Right from the start we should make it clear that this isn’t the Android Pie software update. No, the T825UBU2BSC2 comes with the same Android Oreo UI but with important bug fixes and stability improvement which will smooth up the Android OS that runs by default on your Samsung Galaxy Tab S3. Moreover, the update will add the March 2019 Security Path so now it’s the perfect opportunity for securing your online and offline activity.
The T825UBU2BSC2 is OTA available which means that you should spot the Oreo notification anytime now – if not, you can try to force it down from Settings - > Software update. Also, the same firmware can be applied manually by using Odin since the full software package can be now downloaded from online sources. Thus, you have all the reasons for updating your Galaxy Tab S3 to March 2019 Security Patch.
The update is fully stable and promises a smooth UI and an improved Android functionality. The recently reported bugs are addressed, there are stability improvements added and the security patches should protect your profile on a daily basis. In other terms, it’s possible to receive an improvement for the camera app and for the battery life, therefore, don’t hesitate and check it all out.
For being able to receive the OTA your tablet should already run on official Android OS. Additionally, an official firmware can be received by air only if tweaks weren’t applied – for example, if root was gained you cannot apply the OTA release. In those situations, and not only, a manual update procedure is recommended instead.
Installing the full T825UBU2BSC2 firmware package will, among others, restore your Samsung Galaxy Tab S3 back to its factory settings. Shortly, you will manage to unroot the Android system, to relock the bootloader, to reinstall bloatware and to reapply the stock recovery image. Moreover, you can also use the update process for fixing software related issues including malfunctions like boot loops, lags, hangs, screen freeze, battery drain, heating problems, signal strength issues, or total blackouts.
Odin is the flashing program required in that case. It is developed by Samsung so using it won’t do any harm – no, you won’t have to use other risky and third party apps. Samsung KNOX won’t get tripped so everything should be safe and secured for your Tab S3 while installing the March 2019 Security Patch.
Your personal files should be backed up first though – in rare situations a wipe might be required, which means that your data might be removed from your tablet during the update operation. So, be prepared for the worst and save everything that wasn’t there from day one: personal contacts, texts, images, videos, market apps, internet settings, calendar info and anything else that might be still required in the end. On your Tab S3 you can initiate a backup in different ways: Samsung has dedicated cloud storage services pre-installed on your device, you can use an external storage device, you can sync files with your Google Account, or you can go to Google Play and choose to use already tested and dedicated backup and restore apps.
For this manual update operation you will need access to a Windows powered computer. On that device your Tab S3 drivers must be installed before doing anything else – the Samsung KIES toolkit can help you in that regard. The computer will be the place where Odin will be installed and there you will also have to download the March 2019 Security Patch.
Your tablet and its USB cable must be there too because a connection between your devices will be needed. On your handset access Developer Options and check the USB Debugging feature. Developer Options can be enabled from About Device, by tapping repeatedly on Built Number – after 7 or 10 repeated taps you will receive the ‘you are a developer’ message.
Make sure that there is enough power left on your Tab S3 for the actual flashing process – as a general recommendation, you should plug in the charger first if the power left is lower than 50%. If running on low power during the update operation a sudden shut down might happen. Well, if it does while Odin is running, different malfunctions can cause severe software related problems on your device, so be careful and try not to mess things up.
How to Manually Update Galaxy Tab S3 with Official T825UBU2BSC2 Android Oreo Firmware
- Download Odin on your computer. Run the received file (the executable one) and follow on-screen instructions for setting up the flashing program correctly.
- Download the March 2019 Security patch that’s available for your Samsung Galaxy Tab S3. The T825UBU2BSC2 software file is available on this page. Save it on your desktop.
- Run Odin before heading towards the next step.
- Power off your tablet, wait a few moments and reboot it into download mode: press and hold the Power, Volume Down and Home buttons together until the download mode is displayed.
- Use the USB cable and connect your handset with your computer.
- Odin must recognize your device – the ‘added’ message should appear and the ID:COM section should be yellow or blue. If not, reinstall your Tab S3 drivers on your PC and retry.
- On the flashing program click on AP and then select the March 2019 Security patch from desktop.
- Don’t select the Re Partition and Auto Reboot options from Odin.
- And click on Start when you are ready – now the update operation will be automatically completed.
- The ‘pass’ message will be returned in the end, when the ID:COM field will be turned green.
- Close the flashing program and disconnect your devices. Also, initiate a reboot on your tablet.
If this reboot ends in a boot loop you will have to take action – a boot loop is a problem that can be resolved by making a full wipe from recovery mode. So, in that case force-reboot your Android device in recovery mode: press and hold the Power, Volume Up and Home buttons together until this environment shows up. Next, from the recovery mode menu initiate a hard reset and clear app data cache: select ‘wipe data factory reset’, followed by ‘wipe cache partition’ and by ‘wipe dalvik cache’. In the end return to Android mode and enjoy.
In rare situations you might experience problems while using Odin. For example, the flashing program might stop from running, or its functionality might freeze. In those situations, try to apply these fixes: close Odin and check for any other associated processes that might still run in the background (do it from Task Manager – press the Ctrl+Alt+Del keyboard keys); also remove the USB cable that connects your tablet with your computer; reinstall your Tab S3 drivers on your PC; force-reboot your handset; repeat the flashing steps from the beginning.
