This page will be updated with all of the ways in which you can unlock the bootloader of both the Samsung Galaxy S8 and the Galaxy S8+.
Just like I did with the LG G6 bootloader unlock guide that I wrote up, I’ll be using this guide to detail every single method that enables you to unlock the bootloader of the Galaxy S8 and the Galaxy S8+. You should know that there are a lot of variants of the Galaxy S8 and Galaxy S8+ out there though.
Variants from carriers such as AT&T, Verizon, T-Mobile and Sprint do everything they can to keep the bootloader locked down and do not want you to unlock it.
There are times in which an exploit or something comes out that will let you bypass this restriction though. It is rare, but it does happen on occasion. If there are times in which one of those methods becomes available, then I will add it to this page. So I would advise that you stay updated here if unlocking the bootloader of your Galaxy S8 or Galaxy S8+ is something you want to do. For now though, I will be walking you through how to unlock the bootloader for the international Exynos model (aka the global variant).
Note – This method will work for the Galaxy S8 and Galaxy S8+ with the model numbers – SM-G950F, SM-G950FD, SM-G950X, SM-G950N, SM-G955F, SM-G955FD, SM-G955X and SM-G955N
Galaxy S8 Unlock Bootloader
- Enable Developer Mode on the Galaxy S8
- Launch the Settings application
- Scroll down and tap on the Developer Options option
- Toggle the OEM Unlock option on
- Then tap on the Turn On button
Some OEMs will require that you toggle this OEM Unlock feature on before you go into Fastboot Mode and unlock the bootloader. This is not how it is done for the SM-G950F and SM-G955F variants of the Galaxy S8 and Galaxy S8+ though. As mentioned, the process is incredibly simple and it is very easy to do. Once you have gone through the steps here, you can then use software like Odin to flash a custom recovery onto your device.
So to start, we first need to enable Developer Mode on the Galaxy S8 or Galaxy S8+. You can follow the guide linked above, but it will be a bit different for these Samsung phones. To do this, you’ll need to launch the Settings application and then tap on the About Phone option. From here, tap on the Software Information option and this is where you will find the Build Number option. Go ahead and tap on the Build Number option 7-10 times and it will enable Developer Mode for you.
So now, you can press the Home button to go back to the Home Screen and then launch the Settings application again (or just press the Back button a couple of times). Scroll down all the way on the main Settings page and you should see a new option here called Developer Options. Tap on this and you’ll be shown a ton of unique little features that you can tinker with. Be careful here though because enabling or disabling something here can change the way the Galaxy S8 or Galaxy S8+ operates.
We want to ignore everything except for the OEM Unlock option. This should be toward the top and it’s just a simple toggle that you can flip on and off. By default, it will be set to off and this is what you want to tap on to enable it. You’ll see a dialog box pop up that asks are you sure you want to enable this feature. Simply tap on the Turn On button and you’re done. You can then press the Home button to go back to the Home Screen since your bootloader is now unlocked.
Simply unlocking the bootloader will not trip KNOX, it will not void your warranty, and it will not prevent you from accepting OTA updates. Those things only happen if you modify the core software (like installing TWRP, gaining root access, etc).
