How to Root: Samsung S24 Ultra in 2025 with Magisk v28.1

How to Root: Samsung S24 Ultra in 2025 with Magisk v28.1

The Samsung Galaxy S24 Ultra represents the pinnacle of Android smartphone technology, and rooting it can unlock even more potential. While the process requires careful attention to detail and technical knowledge, the benefits of a rooted device include enhanced privacy features, complete system control, and the ability to run advanced applications. For those seeking these advantages without the technical complexity, pre-configured rooted devices are available from specialized vendors. However, if you're interested in understanding and performing the root process yourself, this comprehensive guide will walk you through everything you need to know about rooting your S24 Ultra, from preparation to completion.

Understanding the Permanent Changes

Before beginning the rooting process, it's crucial to understand that rooting your S24 Ultra will trigger permanent changes that cannot be fully reversed. Even if you later unroot your device, certain features will be permanently disabled due to Knox security system modifications. For those who want to avoid the technical complexity of the rooting process while still enjoying the benefits of a rooted device, pre-rooted S24 Ultra devices are available from trusted vendors like PrivacyPortal (https://www.privacyportal.co.uk/products/samsung-galaxy-s24-ultra-5g). However, if you're comfortable with technical procedures and want to root your existing device, let's examine the changes in detail:

Permanent Feature Loss:

  • Samsung Pay will stop working and cannot be restored
  • Samsung Pass becomes permanently unavailable
  • Secure Folder functionality is lost
  • Samsung Health stops working
  • Galaxy Watch pairing becomes problematic
  • Google Pay may cease functioning

While some features can be restored through custom ROMs or patches, you should carefully consider whether the benefits of rooting outweigh these losses for your specific use case.
