With Galaxy phones running Android 5.0 Lollipop and later, you can find an option, called ‘OEM unlocking’ in Settings > Developer Options. Just by enabling this option, you will have the chance to unlock the bootloader on your device. Once the bootloader is unlocked, you will be able to install a TWRP custom recovery, root your phone to access system files, modify the kernel, and more. Some global/Exynos versions of the Samsung Galaxy S8, S8+, Note 8, or S9 misses out the OEM unlock switch without any reason. So, if you are also in the same trouble, here is a possible fix.
Samsung lets unlock the bootloader on the global versions of their phones. However, on the newest smartphones such as Samsung Galaxy S8, Galaxy S9, and Note 8, the ‘OEM unlocking’ option can only be enabled after 7 days you activate your device and add a Samsung or Google account. If you cannot wait for 7 days or if after 7 days, the OEM Unlock button is still missing, keep reading this post to fix the missing ‘OEM unlock’ button on your Galaxy devices. This method is applied to the Galaxy S8/S8+, Samsung Galaxy S9/S9+ and the Samsung Galaxy Note 8. The latter models are not yet tested, but we think it’ll work on it too. Let’s get started:
How to Fix Missing OEM Unlock Switch on Samsung Galaxy Phones
- First, go to Settings on your Galaxy phone
- Tap on General Management > Date & time;
- Uncheck ‘Automatic date and time
- There will be new options appearing. Tap on ‘Set date’ and choose any date from the last month, so that you can trick the system into thinking that you have used your device for more than 7 days
- Return to Settings >About phone > Software information;
- Tap on Build number 7 times until you see a message: you are now a developer.
- Go back to Settings, and tap on the newly added Developer options;
- Uncheck ‘Auto update system’ option
- Return and go to Software update;
- Disable ‘Download updates automatically’
- Tap on ‘Download updates manually’. You might see an error, but you should worry.
- Once done, reboot your phone
- That’s all! You can see the ‘OEM unlock’ option is now available in the Developer options now.
Once the OEM Unlock option is enabled, you can then unlock the bootloader on your Galaxy device. As we already mentioned, this method has worked well on the Samsung Galaxy S8, Galaxy S8+, Galaxy S9, Galaxy S9+, and Galaxy Note 8.
