[Samsung Galaxy Tab A series Guides, News, & Discus] ghosty999:
These are the steps that worked for me to achieve root on the SM-X110 in the EU

PREP:

- Update Tablet as far as it will go

- Update Windows 10/11 software and drivers

PART 1 - TABLET

1. Boot tablet and go to settings -> about tablet -> software information -> tap on "build number" 5 times to enable developer options

2. Go back to settings and scroll down to new "developer settings" option at the very bottom.

3. Enable OEM unlocking and enable ADB debugging

4. Turn off tablet

5. When tablet is off, hold volume UP + DOWN whilst inserting the charging cable connected to your PC

6. Long press Volume up to enable device unlock

7. Device will reboot

8. Set up device again

9. Download and install Magisk onto tablet - https://github.com/topjohnwu/Magisk

PART 2 - WINDOWS PC

1. On a windows PC download the samsung USB drivers - https://developer.samsung.com/android-usb-driver

2. Ensure your PC can detect and mount the tablet

3. Download Patched Odin 1.13.1B Patched and install - https://xdaforums.com/t/patched-odin-3-13-1.3762572/

4. Download 7zip and install - https://7-zip.org/

5. Download LZ4 https://github.com/lz4/lz4/releases and extract to a folder named appropriately

6. Download firmware for your phone, I could only find the EUX firmware using BiFrost - https://github.com/zacharee/SamloaderKotlin - It will require you to input the Serial/IMEI number of your device to verify. This is a security feature implemented by Samsung in late 2023 I believe.

7. Extract the firmware file (using 7zip) resulting in 4 x files (AP, BL, CSC, HOME)

8. Click the AP file file and extract that (using 7zip)

9. From the newly extract files, copy and paste boot.img.lz4 and Vbmeta.img.lz4 into the folder you you extracted the LZ4 software to.

10. Drag and drop the boot.lz4 file into to the lz4.exe icon, it will create a boot.img file.

11. Copy and paste the boot.img.and Vbmeta.img file onto your Tablet (download folder usually)

PART 3 - BACK TO TABLET

1. Open Magisk App

2. Click install at the top

3. Navigate to the boot.img and Vbmeta.img file and select the boot.img file

4. Wait for the process to complete and a new patched .img file inside the same folder you opened the boot.img file from.

5. Copy and Paste the new patched file and Vbmeta back to Windows PC

PART 4 - BACK TO WINDOWS PC

1. Open 7zip and drag/drop the patched .img file in

2. Create a .tar archive usin the .img file using 7zip

3. After you get a new boot.tar, Drag the Vbmeta. img into boot.tar.

4. Since we can't use TWRP, we have to use Odin to flash the patched boot.tar

5. Launch Odin

6. On tablet hold Volume UP+DOWN and instert cable connected to PC

7. Odin should display "ADDED!". If not, re-install Samsung Drivers / Reboot PC.

8. In the AP section, select your patched boot.tar

9. If you are using the WiFI only mode, skip mounting the CP. If you have the 4G model, mount the CP from the originally extracted firmware download

10. Mount the BL and CSC from the originally extracted firmware download

11. Under "Options" in Odin, de-select "Auto Reboot"

12. Click "Start"

PART 5 - BACK TO TABLET

1. Press the Volume DOWN + Power button to exit Download

2. Immediately Press the Volume UP + Volume DOWN + Power buttons as soon as the screen goes off. This boots into recovery mode

3. Go to Wipe Data/Factory Reset and Select Yes to wipe data

4. Reboot phone

5. Magisk should now displayed that it's installed and you can now install modules.

Thanks, hope this helps! I may do a further guide on passing safetynet and CTS.
