Samsung Globally Removes Bootloader Unlock Option with One UI 8, Ending Custom ROM Freedom
With One UI 8, Samsung removes the boot loader lock from the developer options-not only for US users, but worldwide. The change will probably affect all devices from the Korean manufacturer because the corresponding code has been completely removed.
Samsung tightens bootloader restrictions
With the One UI 8-update, Samsung limits user freedom for Galaxy devices considerably. While US users have not had a chance to block boot loader for years, this option has so far been available in other regions. With One UI 8, this is now changing fundamentally – the restriction then no longer only applies regionally, but worldwide. The “OEM Unlocking” option in the developer settings has disappeared both in beta versions of the Galaxy S25 Ultra and the new Galaxy Z Flip 7 and Z Fold 7. Tests confirm that international models are no longer displaying the corresponding switch in the developer options. This change marks a significant change of course in Samsung’s strategy regarding freedom of users.
Technical analysis shows complete distance
A user on XDA named Salvo_giangri discovered when analyzing the new firmware (via Sam Mobile) that Samsung inserted a decisive line in the boot loader configuration: “Androidboot.other.locked = 1”. This setting prevents the settings app from showing the OEM Unlock option. More than that, because Samsung continued.
The technical analysis shows that not only the user interface has been changed, but the entire code for the boot loader drawer was removed from the boot loader. This also makes technical transition solutions impossible, since the corresponding functionality is completely missing. Even experienced developers can no longer implement updates or the like.
Background for the Bootloader Center
The boot loader memory was traditionally an important feature for Android enthusiasts. It enables the operating system to modify, install custom ROMs and to obtain root access. Many users use these options to use older devices longer by alternative firmware or to unlock additional functions. Samsung had already removed this option in the United States for legal and security reasons. Mobile operators such as Verizon and AT&T often require manufacturers that devices cannot be unlocked to protect their own software adjustments. However, the option remained available in other markets – until now. For most Samsung buyers, this change has no direct effects, since the majority of smartphone users do not use such expanded options anyway.
However, this represents a significant setback for the Samsung enthusiasts community. For friends of alternative ROMs, the reports are particularly questionable, which indicate that already unlocked devices could be automatically blocked when updating to one UI 8. The manufacturers mainly justify such measures with security concerns and protection against malware. However, critics see this a restriction of user rights and an extension of the planned obsolescence, since alternative firmware solutions can often extend the lifespan of devices.
