How to Root Your Samsung Galaxy S24: A Developer's Guide


Rooting your Samsung Galaxy S24 opens the door to full system control, advanced debugging, and developer-level operations. This article will walk you through the process, precautions, and the post-root possibilities for a professional developer.


Understanding Rooting

Rooting is the process of gaining superuser (root) access to your Android device. On a Samsung Galaxy S24, root allows you to:


Modify system files and settings


Run root-only applications


Conduct advanced debugging and development operations



Warning: Rooting trips Samsung Knox permanently, which disables Samsung Pay, Secure Folder, and some banking apps. Additionally, unlocking the bootloader wipes all device data.

Prerequisites


Before starting, ensure you have:


A Windows PC with Samsung USB drivers installed


USB cable and ADB tools


Official firmware for your S24 model and region


Latest Magisk Manager APK from the official GitHub repository


Odin flashing tool (v3.14.x recommended)


7-Zip or equivalent archive extraction tool


lz4 tool for decompressing boot images (if necessary)




---


Step-by-Step Rooting Process


1. Backup Your Device


Backing up all personal data, photos, app data, and developer projects is critical. Use Google Drive, manual copies, or ADB backups.


2. Enable Developer Options and OEM Unlocking


Navigate to Settings → About phone → Build number and tap 7 times to enable Developer Options. Then enable OEM unlocking and USB debugging.


3. Unlock Bootloader


Power off the device.


Enter Download Mode (Volume Down + Power).


Confirm bootloader unlock (this will factory reset the device).



4. Prepare Firmware and Boot Image


Download official firmware matching your model and region.


Extract the boot.img from the firmware .tar.md5 file using 7-Zip.


If compressed (boot.img.lz4), decompress using lz4.



5. Patch Boot Image with Magisk


Install Magisk Manager APK on your phone.


Transfer boot.img to /sdcard/Download.


In Magisk Manager, choose Install → Select and Patch a File → boot.img.


Magisk will create magisk_patched.img.



6. Package Patched Boot for Odin


Transfer magisk_patched.img to your PC.


Package it as AP.tar for Odin flashing using a tar utility.



7. Flash Patched Boot via Odin


Enter Download Mode.


In Odin, select AP → AP.tar, check Auto Reboot and F. Reset Time, do not check Re-Partition.


Click Start and wait for the flash to complete.



8. Verify Root


Open Magisk Manager to confirm installation.


In Termux:



pkg install tsu

tsu

whoami


Should return root.

Post-Root Operations for Developers


Rooting unlocks a wide array of operations useful for developers:


System and App Debugging


Inspect logs: logcat -b all -d > /sdcard/full_logcat.txt


Modify SELinux temporarily: setenforce 0


Explore system files: adb shell su



Full Backup and Restore


Use dd to dump partitions: dd if=/dev/block/by-name/boot of=/sdcard/boot_backup.img bs=4096


Full Nandroid backups possible with custom recovery.



Network Analysis


Capture network traffic with tcpdump: tcpdump -i any -s 0 -w /sdcard/capture.pcap



App Instrumentation


Deploy Frida server or gadget for dynamic analysis.


Access app private data for debugging:



run-as com.example.app

cp /data/data/com.example.app/databases/app.db /sdcard/


Kernel and Performance Tweaks


Adjust CPU frequency and governors:



echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor


Flash custom kernels for benchmarking, power, and thermal control.




---


Security and Best Practices


Only grant root access to trusted apps.


Keep a backup of the stock boot image and firmware for recovery.


Re-enable SELinux after testing: setenforce 1


Regularly update Magisk and modules; monitor community forums for device-specific advisories.

Rooting the Samsung Galaxy S24 provides unparalleled control for developers, from low-level debugging to custom performance tweaks. With careful preparation, following proper procedures, and understanding the security implications, developers can harness the full potential of the device for development, testing, and experimentation.




Done — I’ve created a comprehensive article-style guide titled “How to Root Your Samsung Galaxy S24: A Developer's Guide” covering the entire rooting process, prerequisites, and post-root developer operations.


You can now use it as a standalone reference or publish it as a blog/tutorial.

🕊️ Introduction On 4 August 2025 , Lesotho lost one of its brightest lights — Mr. Lephoto Nabi (Nabi Raphael Lephoto) . A pioneer in technology, a devoted educator, an entrepreneur, and above all, a human being whose presence uplifted everyone he encountered. Not leaving out the love he had for his Basotho Nation in general, attested by the community projects he embarked on.  For me, this loss is profoundly personal. He was not only my lecturer but also a mentor, a guide, to many other Basotho Youth - an inspiration who shaped my academic path, industrial outlook, social values, and entrepreneurial vision.  This blog is my humble attempt to celebrate his life, legacy, and the immeasurable impact he had on me and countless others . 🎓 Academic Excellence: Cisco Certified Lecturer I had the privilege of sitting under his guidance as my lecturer for Ethical Hacking under the Cisco program at Lerotholi Polytechnic , where he served as Head of the IT Department .

Academic Compliance and Quality Assurance in Higher Education: Safeguarding Integrity and Trust By: Tlokotsi Potloane Lerotholi Polytechnic Email: tpotloane1967@gmail.com Programme: BEng in Computer Engineering – Year 3 1. Introduction In any academic institution, maintaining integrity, transparency, and adherence to educational standards is not just a regulatory necessity, but a societal obligation. When students are evaluated under inconsistent academic conditions — such as syllabus misalignment, selective leniency, concealed moderation procedures, and unequal awarding of marks — the consequences can extend fain r beyond the individual student. These failures reflect systemic weaknesses that threaten: The credibility of qualifications The trust of government and funding stakeholders Institutional reputation Legal sustainability of academic programs 2. Regulatory Framework and Standards Educational institutions are bound by national and institutional quality assurance regulations, suc...

ADHD - Thirteen Years in the Dungeon

  The Struggle Within: A Journey Through ADHD, Self-Medication, and the Destructive Pursuit of Perfection Introduction: A Mind in Overdrive From a young age, my mind has been a storm—a constant whirlwind of thoughts, impulses, and distractions that never seem to quiet down. It was as if my brain was wired differently, operating at a frequency others couldn’t hear. ADHD was the name for this chaos, but it wasn’t a diagnosis I could easily access. In Lesotho, where support for ADHD is practically nonexistent, I resorted to a self-diagnosis that led to a long, tumultuous battle with self-medication. My academic successes, my company, my family’s pride—these were the masks I wore to cover the turmoil inside. But behind those accomplishments was a person spiraling, holding the facade together with chemical crutches. The Cunning Facade: Masking ADHD’s Telltale Signs At first, I only showed the symptoms of ADHD to those who could help me maintain my self-diagnosis. My impulsivity, inabili...
