Tablet Preparation

Before starting the flashing process, make sure your device is properly set up to avoid any issues.

Important Note

Make sure your device is well charged and back up any important data before starting the steps.

Egypt Specific: For 2020 High School Students with SM-T585 Tablets

• If you're from the 2020 batch, pay attention to this before downloading any ROM - you need to know your device's drivers first.

• To know if your device has old or new drivers, download the Device Info HW app (link below the note).

❏ Look at the touchscreen information:

➩ If it says d_fts_touch, then you have new drivers.

➩ If it says fts_touch, then you have old drivers.

• If your device has new drivers, make sure before downloading any ROM from the site that it says Rev05/07, which means it supports both old and new drivers.

• If it only says Rev05, it means it's for old drivers only.

• To make it easier for you, go back to the main page of the site, and from the side menu choose Rev07 ROMs Support where you'll find all ROMs supporting new drivers gathered in one place, and you'll also find a link below.

Download Device Info HW

1. Enable Developer Options

Go to Settings > About Device > Tap on Build Number 7 times until the option is enabled.
Return to the main Settings page, you'll find Developer Options activated.

2. Enable OEM unlocking and USB debugging "Unlock Bootloader"

In "Developer Options", enable the following options:
- OEM unlocking
- USB debugging

Very Important Warning

If you don't unlock the bootloader (Step 2), you'll get this error message: Custom binary blocked by FRP lock with the first reboot after flashing, and to fix this problem you'll need to flash the original "Firmware" (you'll find the tutorial and download links below).

Flash Original Firmware

3. Enter Download Mode

Power off the device, then press and hold (Volume Down + Home + Power) together, and when the green screen appears, press the Volume Up button to confirm.

If you prefer to flash recovery via PC using Odin, you can proceed directly to the next part of the tutorial.

Note

You'll find download links for the Eros app and recovery file right below the tutorial.

1. Requirements

Another Android phone with the Eros app installed.
The recovery file twrp-3.7.0_9-0.tar downloaded on the phone.

You'll see a message from the app asking for permission to access, press OK.

Warning

If your device is running Android 12 or higher, and the Eros app doesn’t detect or recognize your tablet, go to Settings > Bluetooth & devices > and enable the OTG option. You might find the same option in some older Android versions, and if the connection still doesn't work, try doing a Restart of the Download Mode or try another cable.

3. Select the Recovery File

After successful connection, you'll see a Connected Device message at the top.

Flashing TWRP with PC

Note

You'll find all file and tool download links right below the tutorial.

1. Preparing Odin

Install USB drivers on the PC, run the Odin program and connect the tablet. You should see the "added!!!" message.
Press the AP button and choose the "twrp-3.7.0_9-0.tar" file.

2. Disable "Auto Reboot"

In the "Options" section in Odin, remove the checkmark from "Auto Reboot".

3. Start Flashing the Recovery

Press "Start" and wait for the green "PASS!" message.

Warning

The next step is important, please read it carefully and understand what's required before executing it, so the recovery works without problems.

4. Enter Recovery Mode

Press and hold the (Volume Down + Home + Power) buttons together to power off the device.
As soon as the screen turns off, immediately press (Volume Up + Home + Power) until the Samsung logo appears on the screen.

Warning

• If you make a mistake in the previous step and the device enters stock recovery, you'll need to reflash the recovery and perform the steps again.

• If the TWRP logo appears, it means you've successfully flashed the recovery.

Note

When TWRP recovery runs for the first time, it will ask if you want to use it in "read-only" mode. To allow modifications, swipe the arrow to confirm allowing changes.

5. Format Data

In TWRP, choose Wipe > Format Data and confirm by typing yes then press the ✔ mark and wait until the data formatting process completes.

6. Reboot to Recovery

Return to the main menu, choose Reboot then Recovery.

Important Note

➩ Up to this point, the first part of the tutorial is complete (unlocking bootloader + flashing custom recovery TWRP).

➩ The remaining steps will be specific to flashing custom ROMs, and also explaining how to root using either Magisk or APatch.

➩ If you don't plan to install a custom ROM and want to stay on the official Stock ROM, you can proceed directly to the root section to learn how to install it.

➩ To exit recovery mode: return to the main menu, choose Reboot then System.

Very Important Warning

If you decide to stop at this step and stay on the Stock ROM without installing a custom ROM, don't disable developer options from settings. Because if you do, you'll get this error message: Custom binary blocked by FRP lock as soon as you reboot the device, and then you'll have to flash the Stock "Firmware" to fix the problem.

Terminology You'll Encounter

Types of ROMs

Types of ROMs by Source

• Stock ROM: The official version that comes pre-installed on the device from the manufacturer. It's stable and secure, but usually has fewer features and customization options.

• Custom ROM: A modified system developed by independent developers. It has additional features and customizations not available in the official version, and sometimes better performance.

• Ported ROM: A ROM from another device (usually from the same manufacturer or similar processor) that has been modified to work on your device. It offers new features but might have some minor issues.

• GSI ROM: A generic system that can run on many devices supported by the Treble project. It gives you the opportunity to try the latest Android versions even if your device hasn't received an official update.

Types of ROMs by Google Services

• Vanilla ROM: A raw Android ROM without any Google services or apps. Suitable for people who want a lightweight device or to manually add the services they prefer.

• GApps ROM: The same ROM but integrated with basic Google services and apps (Google Play, Gmail, YouTube... etc). Suitable for those who want all Google services ready after installation.

• MicroG ROM: A ROM that uses an open-source alternative to Google services called microG. It provides features similar to Google services but with less battery and resource consumption, and also gives you higher privacy.

Flashing Custom ROM

Beginning of Part Two

In the previous step, we performed Format Data through the custom recovery TWRP, and this step is very important if this is the first time you're flashing the custom recovery. Now let's continue with the remaining steps to flash the custom ROM.

1. Advanced Wipe

In TWRP, choose Wipe > Advanced Wipe, and select all options except SD Card, USB OTG, and Internal Storage.

2. Flash the ROM

Transfer the ROM file ROM.zip and the GApps.zip file (this file is optional depending on your need for Google services on the ROM) from the PC to the tablet.
In TWRP, choose Install, select the ROM .zip file, then use Add more Zips to add the GApps file, then swipe to confirm the flashing and wait for the process to complete, then click reboot system.

Important Note

After starting the flashing process, if you see a failed message and a red error like this:

Zip file is corrupt!

This means the ROM file is corrupted. The reason might be a problem during download or while transferring the ROM file from PC to tablet. All you need to do is transfer the file again and try flashing once more. If the error appears again, it means the problem is with the file and you should download the ROM file again.

Rooting with Magisk

1. Prepare Magisk File

Download the Magisk app .apk and change the extension to .zip.

2. Flash from Recovery

Flash the Magisk.zip file from recovery using the same method as flashing the ROM through the Install option.

Reminder

To enter custom recovery: power off the device, then press and hold (Home + Volume Up + Power) together until the Samsung logo appears on the screen.

3. Complete Installation

After rebooting the device, install the Magisk .apk app to manage root permissions.

Download Magisk

Alternative Method: Rooting with APatch

Warning

➩ Only supports ARM64 architecture.

1. Create Patch Through the App

Download the latest version of the APatch app from GitHub (download link below).

2. Select Boot File

Extract the boot.img file from your ROM file, tap on the patch button in the top right corner of the app, and tap on Select a boot image to patch.

3. Specify boot.img File

Select your boot.img file (which you extracted earlier).

Note

Root Key (SuperKey) that you'll create now is very important, as it's the key that will enable you to get root access. Make sure to save it properly for later use.

4. Set SuperKey

Set the SuperKey in the "SuperKey" card. It should be 8-63 characters long and include numbers and letters, but without special characters.

Warning

It's strictly forbidden to set weak keys like 12345678. The latest APatch versions require using strong keys.

5. Start Patching Process

Tap on "Start" and wait a few seconds until patching completes.

Note

After successful patching, the path of the modified boot.img will be displayed. For example:

/storage/emulated/0/Download/apatch_patched_11107_0.12.0_equt.img

6. Flash the Resulting File

Finally, flash the modified boot.img file (Patched) via recovery. From the Install menu, press Install Image, select the file, then choose to flash it as the boot partition, then swipe to confirm.

Reminder

To enter custom recovery: power off the device, then press and hold (Home + Volume Up + Power) together until the Samsung logo appears on the screen.

7. Enable Root Permissions

After rebooting the device, open the APatch app and press on SuperKey. Enter the key you created earlier during patching to get root access.
