Samsung Locks Down Bootloaders in One UI 8: The End of Custom ROMs?

Samsung's One UI 8 completely disables bootloader unlocking. Analysis of system files reveals that One UI 8 permanently sets the `ro.boot.other.locked` parameter to 1, removes the OEM unlock toggle, and strips all unlock-related code from the bootloader. This means devices like the Galaxy Z Fold 7, Z Flip 7, and Galaxy S25 series will be unable to install custom ROMs, gain root access, or use custom kernels, dealing a significant blow to the Samsung developer community.
