After successfully rooting my S10 i realised that i didn't quite needed it and it didn't advantage me to much so i re flashed it all back to the stock firmware and the phone is working fine however, i am struggling to re lock the bootloader.

I have an Australian Exynos version. When i reboot to download mode through ADB on my Windows PC and then try to lock it following the usual fastboot commands, i just get <waiting for devices>. I read some where that it's a driver issue so i updated all my drivers, well i think i did but still not having much luck.

I also tried on my Mac but i keep getting an interface error which from what i've read is a MacOS issue that has been broken for a while.

Can anyone help please? I want to re-lock it so that i can sell it.

If I configure the phone with access to the Internet, because I have something in the developer's settings, the OEM can not be moved in gray.
When he sets up the phone without internet, there is nothing.

As others have mentioned, mine too is greyed out. Any idea how to re activate this setting or what causes it to not be editable?

It's the same on mine, not that I need to lock the oem but I'm more concerned about when it's time to sell it back.

No one is going to buy a phone that say Everytime it boots "security issue"

Exactly my issue as well... no one is going to buy a phone with the "security issue" warning!

Try to reflash everything stock.

If this doesn't work, congrats, you played yourself and discovered the inconveniences linked to wanting root on a European Samsung device.

Put it in the download mode. I believe 2nd option to turn off oem lock. Dont be silly. You always put back stock firmware and pretend like nothing happen to the phone.
