I've found numerous guides online on how to fix the missing OEM unlock toggle on samsung galaxy s9. I've been able to follow all steps except for the last one before rebooting the phone. And that step is going into software update and unchecking download updates automatically and checking download updates manually. The problem is that those options don't exist! I can only tap on Check for updates and there's a grayed out option that says Continue update. I don't know if this is true but I think it's the same as going into developer options and switching off auto update system, which I was able to do. Either way, I still wasn't able to fix the missing button, even after following this guide I was just talking about. I've seen other guides and they talk about the same thing that this one does. Can someone help me unlock my OEM unlock button please? Some device info:

Model number: Samsung Galaxy S9 (SM-G960U)
Android Version: 10.0

EDIT: As of now, I played around with my phone and found out the reboot to bootloader option in the menu after starting the phone with power key + volume up + bixby key. I didn't know what that was going to do but when I selected that, a light blue screen came on and said downloading... do not turn off target. There's an option to cancel it but I want to see what happens. Maybe I didn't have a bootloader at all? (sounds crazy because I need a bootloader to start my phone so maybe it's downloading something else?). In either case, I'll keep this question posted with any new info.

  • guess U models are not unlockable. what is your chipset, csc, bootloader version

  • How do I check any of those things? I can't find it in about phone Feb 14, 2021 at 23:23
  • I've backed up my data via SD Card and cloud. Is that going to help at all? BTW I think the csc code is ATT Feb 14, 2021 at 23:26

  • So my bootloader version is 190711 because it's the 5th digit from the build number (or 1 if that's the only digit you're looking for) Feb 14, 2021 at 23:32
