[Samsung Galaxy Tab A series Guides, News, & Discus] Reick7:
Hello guys, decide to mount this tutorial because I still see a lot of people with doubts, yes we already have how to root our device :o

I did it on mine and it worked, do it at your own risk, neither I nor anyone else on the forum is responsible for any loss

A tutorials too complex for some users, teaching you how to create your own Magisk modified Img boot, but I like simplicity, so if you don't want to break your head too much, here's a tip, use a successfully modified img boot , what you need is to install the rom stock that was used to create the modified boot first.

let's go to the tutorial, warning that the files posted here are not my own, and if it doesn't work, check if you're not commenting on any flaws, don't try to memorize the tutorial, follow it step by step. come on!:dedos cruzados:

1 - first follow these steps to unlock the bootloader:

This is a basic step to root device. Go to settings - about phone - Software Information - tap multiple times on "Build number" - This will open developer option.

Now in settings at the end, you will have new option "Developer options" - look for OEM unlocking - Enable it.

(PS : If you don't see this option then you may need to wait up to 7 days or more to appear or may be on some operator you will get it never. Without this option you can not root your device, sorry!)

Once you have enable OEM unlock option, switch off your device and reboot to download mode.

To put device in download mode - Press Volume Up & then Press Volume Down (Keep holding both) and connect device to PC with USB cable

When device start to download mode,long press volume up to unlock the bootloader. This will wipe your data and automatically reboot

Now let finish setup and again enable developer options (as said above), and confirm that the OEM unlocking option exists and grayed out!

If it is not then you can not root device!

Once you see this option and greyed out, you are ready to flash custom binary and root your device.

Now let's go to the next step, reinstall an outdated system, I did it on mine and it worked, do it at your own risk, neither I nor anyone else on the forum is responsible for any loss

2 - installing the stock ROM that we will use:

download this rom: https://samfrew.com/ru/download/Gal..._Wi-Fi-__/rue3/KOO/T290KSU3BUE1/T290KOO3BUE2/

OBS: a little detail about this firmware, it is made in arm32, which apparently makes it "lighter", but also has a more acidic use of RAM memory. This was the last software I installed on tab A, and I can say that the use has become better with it, but if you want to stay in the stock rom, even custom gsi didn't get such a good performance. It's worth testing, but be aware of the risks, I'm not responsible for errors.

Updating: use a modified version of Odin, to do the installations, be careful with downgrades, I managed, I was in the most current version of March, and I managed anyway using this modified Odin, but do it at your own risk, download the most current version here:

https://xdaforums.com/android/software/patched-odin-3-13-1-t3762572

And install via Odin, if you need more details just a Google, there are already millions of tutorials for that lol

when you get here you should already be aware that you have lost all your data, but it is necessary that the OEM option is enabled in the options, so in the CSC session use Home CSC, so that you leave the data saved, and do not lose the initial settings : )

once with successful installation, we will now install the file modified by magisk

3 - magisk Installation:

Intall TWRP: https://xdaforums.com/t/recovery-unofficial-twrp-3-5-2-for-2019-galaxy-tab-a-8-0-sm-t290.4185235/

just follow our friend's tutorial, with a little observation, after starting the process in odin, be sure to hold the volume up button + turn on, to be redirected to the TWRP.

follow the standard steps to install magisk, if it doesn't work, you will have to manually modify the system boot.img along with magisk maneger.

if case of problem:

The process of entering recovery on the SM-T290 using buttons is really finicky, unlike the 10.1" version. My best result has been with holding Power + Vol Up on startup, quickly switching to hit Power to dismiss the bootloader unlock warning page, and then immediately holding Power + Vol Up again for 6 seconds. (Holding longer will cause a hard reset.)

If you miss on the first attempt and haven't installed Multidisabler, it will revert your custom recovery to the stock OEM recovery.

I haven't had the tablet in my hands for a few months, so unfortunately I can't help more than that, as I said this was the last system I used, just because GSI are not very functional and are not always light, sometimes they crash more and it has more annoying bugs to fix that discourage daily use. my tip is, stay in stock Koo, excuses for those who can't, the most I can do now is guide them.

As a gift for you, I will teach you how to use Xposed :3

remembering, I did several tests that several times I faced bootlooops :( but in the end it worked for me, so notice, do it at your own risk.

5 - How to install end use EDexposed with Magisk

these versions were the ones that worked without problems in this rom

Install Riru - (Riru core) V21.0

Install Riru - Edxposed v 0.4.6.1(4510) YAHFA

Reboot, after reboot, install Edxposed Manager

and you can be happy :)

I thank you all for your help, and remembering that this was just a compilation of tips, to facilitate everyone, take due care to avoid problems, and don't forget to thank: 3 ?
