5. Associated Risks and Warnings

Users must be aware of the following critical risks before proceeding: Prerequisites:

Knox Warranty Void: Samsung utilizes a hardware fuse (Knox). Once the bootloader is unlocked, this fuse is blown permanently. This voids the warranty. Samsung Service Centers will refuse repairs (even paid ones) for software/hardware issues related to the mainboard.
Samsung Knox Security Loss: Banking apps (Samsung Pay, Google Pay) and secure folders will detect the root/custom ROM and refuse to run. Workarounds (Magisk Hide/Zygisk) exist but are inconsistent.
SafetyNet/Play Integrity: Custom ROMs often fail Google's SafetyNet checks, resulting in apps like Netflix or banking apps not appearing in the Play Store or crashing.
Camera Quality: Samsung's image processing is proprietary. Custom ROMs use generic drivers, resulting in significantly worse photo quality compared to Stock One UI.
