I have a Samsung handset that is currently running an Android 16 build. I need reliable, repeatable full read-write access to the /system, /vendor, /product and /data partitions so I can dig into protected configuration files and perform low-level testing. A non-destructive method that keeps Knox intact and avoids tripping irreversible flags would be ideal; however, I am prepared to proceed with a conventional root approach if that is the only route that genuinely works on this firmware. Magisk-patched boot images, custom recovery, kernel-level exploits, or even a temporary live-USB solution are all on the table—what matters is that the end result lets an adb shell drop into true root without boot-loops or SafetyNet issues. Deliverables • Step-by-step instructions tailored to this specific Samsung model and Android 16 build • Any images, scripts or binaries required (patched boot.img, Magisk modules, etc.) • Verification steps that show root privileges are active (screenshot or video of adb shell # prompt and successful write to /system) • Roll-back or cleanup procedure so the phone can return to stock if needed Please highlight any known risks—OTA update breakage, Knox tripping possibilities, data wipes—so I can evaluate them before flashing. If you have performed a similar unlock on the same or newer Samsung firmware, that experience will be a plus.
