Why Samsung’s One UI 8 Might Be Blocking Bootloader Unlocking

Samsung’s new One UI 8 update could mark the end of bootloader unlocking on Galaxy phones, leaving custom ROM fans disappointed. Bootloader unlocking—an essential feature for developers and power users—has quietly disappeared in the latest beta builds, including those for the Galaxy S25 series. This sudden change is sparking concern across the Android community, especially outside the U.S., where this feature was previously accessible. If you’ve been wondering whether you can still install custom firmware or root your Galaxy device running One UI 8, the answer may soon be a hard "no."

Bootloader Unlocking Removed in One UI 8

Early adopters of One UI 8 noticed something alarming: the toggle to unlock the bootloader is missing. Devices like the Galaxy Z Fold 7 and Galaxy Z Flip 7, which come preloaded with the latest interface, no longer support bootloader unlocking—even in regions where the option was previously available. This change came to light through XDA Developers and was confirmed by code found within the system’s Settings app. Specifically, a new parameter labeled androidboot.other.locked=1 now locks down the bootloader by default.

Custom ROM Community Could Face Major Setback

For years, Samsung devices (outside the U.S.) allowed users to unlock their bootloaders and flash custom software. This gave users more control over performance, privacy, and system design. But with One UI 8’s new restriction, even developers may face hurdles in tweaking or testing software. The change also appears in One UI 8 beta builds for the upcoming Galaxy S25, signaling this may not be a temporary or device-specific shift but a new global policy from Samsung. Unless a workaround is found, future Galaxy phones may no longer support bootloader modification.

What This Means for Power Users and Developers

Samsung’s decision to restrict bootloader access on a broader scale could significantly change its relationship with the Android power-user community. Rooting a device, removing bloatware, or installing lightweight custom ROMs has been part of the Samsung experience for many. By enforcing these new limitations, Samsung may be prioritizing security and warranty protection over customization. However, users who value control and flexibility may be forced to explore alternatives—like Pixel devices or brands more developer-friendly. It's unclear if Samsung will reverse this decision, but for now, One UI 8 represents a shift toward a more locked-down ecosystem.
