Are you still using the Samsung Galaxy Tab S2 8.0? If you are and if you still want to enjoy a stable and smooth Android experience regardless of the apps you choose to download and run, I recommend you to replace the stock Android firmware with a custom ROM platform. And in that respect you can now use the latest build of Lineage OS: Lineage OS 15.0 which is powered by Android 8.0 Oreo.
Yes, that’s right; now you can update your very own Samsung Galaxy Tab S2 to the latest Android system, so this is a big update opportunity for you. Anyway, before choosing to apply the Lineage OS software read all the lines from below. There we will discuss about the advantages and risks implied and about the pre-requisites that must be applied before anything else.
This is not the official roll out of LineageOS 15 but a custom one. The xda senior member LuK1337 managed to port the Android 8.0 Oreo software and customize it in order to run on the Samsung Galaxy Tab S2 8.0. So, this update is still under development stage but that doesn’t mean you cannot use it on a daily basis. In fact, the ROM will run without any sort of issues – rarely you might experience minor bugs or lags though.
LineageOS 15.0 for Samsung Galaxy Tab S2 8.0 is light and fast. The ROM isn’t pre-loaded with bloatware but only with essential features that can improve the overall Android experience. So, bottom line, with this Android 8.0 Oreo based firmware installed your tablet should run better and even faster, everything while you can enjoy an improved battery life.
Now, for avoiding any possible problems, you should begin this guide with a Nandroid backup operation. This particular backup process will save the Android OS that currently runs on your tablet – so, if the Lineage OS will not run as you expected, or if you will think that the stock ROM was better, you will be able to use the Nandroid backup package for going back to stock Android.
Samsung stopped the official support for the Galaxy Tab S2 8.0. So, this is an unofficial update opportunity that cannot be associated with your OEM or with Google. Unfortunately, Samsung KNOX will get tripped during the flashing process – the warranty will get lost. If you somehow will need to restore the warranty mark on your tablet you will have to reinstall the stock Android firmware, a process that can be applied by using Odin.
Updating to Android 8.0 Oreo via LineageOS 15.0 is possible only if your Samsung Galaxy Tab S2 8.0 is rooted. The root process will unlock the Android OS that currently runs on your tablet – an unlocked system is required because the new Oreo firmware will have to access, modify and customize it along with other built-in features, apps and capabilities.
Moreover, a custom recovery image must be installed on your device. Through this dedicated and specialized environment you will afterwards flash the Lineage OS package. Now, for making things work without experiencing any problems and also for making your job easier you should use TWRP recovery.
The update operation can be completed only if a hard reset is applied – so, a clean storage system is required when a custom ROM is flashed. That’s why you should now think about saving your personal data, info, accounts and files – only by backing up everything you can still use your files afterwards. Thus, use the built-in cloud storage services that run on your Galaxy Tab S2, or choose to sync your files with your own Google Account; another way in which you can secure your data is by downloading compatible backup and restore apps from Google Play.
You need to use a computer because the Android 8.0 Oreo based Lineage OS 15.0 custom ROM firmware must be downloaded there first. Also, your tablet and its USB cable are required – as you can tell, a connection between your PC and your handset will have to be established. So, because of that, on your device you need to check the USB Debugging field first – this feature is located under Menu – > Settings – > Developer options. Hint: for accessing Developer Options you first have to go to About Device and tap repeatedly on Built Number until the ‘you are a developer’ message is being displayed.
Ensuring just enough power for the actual update operation is also an important aspect that should be considered. As a general idea, if your tablet will somehow get turned off right in the middle of the flashing process you will risk in ending up with a soft bricked Android software – different malfunctions can be caused in that situation. So, verify the power that’s left and if it’s lower than 50% you should take your time for completing a charging process.
Don’t mess things up: the Android 8.0 Oreo powered LineageOS 15.0 custom ROM offered below is compatible only with the Samsung Galaxy Tab S2 8.0.
How to Update Samsung Galaxy Tab S2 8.0 to Android 8.0 Oreo with LineageOS 15.0 custom ROM firmware
- Begin by downloading the LineageOS package – you can get it from here.
- Also download compatible Google Apps – this package is not included in the Android 8.0 update system; you can download Google Apps from here.
- Save both files on desktop or somewhere where you can easily access them.
- Meanwhile, switch off your tablet and also wait a few moments until the shut down process is completed.
- Then, reboot recovery mode: press and hold the Power, Volume Up and Home buttons together, for a few moments.
- From recovery make a hard reset and clear app data cache by choosing “wipe data factory reset”, followed by “wipe cache partition” and by “wipe dalvik cache”.
- Return to main menu of recovery when done and pick up ‘reboot system now’.
- You need to connect your tablet with your computer now – just plug in the USB cord.
- Select the downloaded files from desktop and copy-paste them on your tablet; afterwards unplug the USB cable as the computer is no longer required.
- Enter recovery mode on your Samsung Galaxy Tab S2 again.
- From recovery tap on Install, load the update package and swipe in order to start the update process – if TWRP recovery isn’t used you will have to choose “install zip from SD card” and “choose zip from SD card”.
- Wait while the flashing process is completed and when done repeat the last step and install Google Apps.
- In the end, return to main menu of recovery and choose ‘reboot system now’.
