I guess this does not work on the latest Samsung A03s, as all mine does is go into the download menu, and never displays the menu to unlock the bootloader… anyone else had this experience? Is there another way to do this? I have developer’s options on, but, the OEM option never shows up on the menu, I’ve tried changing the date to manual method as suggested, but again, I never see the option. Has Samsung yet again closed a loophole?
