Galaxy S9 Plus OEM Unlock

Samsung flagships are always a sight for the sore eyes, especially for the Android community that indulges is rooting and tweaking devices. This is the very reason why less than a month since its launch, the Galaxy S9, and S9+ have not only been given root capabilities, but there’s already official TWRP recovery and even an AOSP custom ROM ready for the devices.

If you’re among the tweakers who always love to get more out of their devices, jumping on the rooting train for Galaxy S9 may seem like a no-brainer. However, several users have reported that the OEM Unlock option that is necessary to root your Galaxy S9 and S9+ seem to be missing completely.

Why can’t I see OEM Unlock option?

To start things off on the right foot, Samsung Galaxy S9 and S9+ users who own the Snapdragon variant of the device, there’s no point in looking for the OEM Unlock option. The rooting capabilities and official support for TWRP custom ROM are only extended to the devices running the Exynos processor, so you won’t have any luck with the OEM Unlock option anyways.

There are also a bunch of users reporting that the OEM Unlock option is missing by default even from their Exynos variants, and the unfortunate part is there is no solution to it. This probably has to do with the carrier-locked Galaxy S9 devices or a regional issue, but the fact of the matter is that there’s no other way to it.

OEM Unlock option disappeared

If you enabled the Developer Options and noticed the OEM Unlock there before but can’t find it anymore, there could be another reason for it. It is a possibility that you’ve already enabled OEM Unlock, at which point the feature will most likely disappear from the Developer Options menu. The OEM Unlock option is hidden away by the software for 7 whole days after the mandatory factory reset, after which you will be able to see and enable/disable it from the Developer Options menu.

Be careful when enabling OEM Unlock

Samsung added an extra layer of security since the release of Galaxy Note 8 in regard to the OEM Unlock option. This security feature essentially forces the device to reset to factory settings — a mandatory factory reset, once you restart the device — after you enable the OEM Unlock option from the Developer Options menu.

So once you have enabled OEM Unlock, the next time you reboot your Galaxy S9 or S9+, it will delete all of your personal data.

Is there a way around it?

If you do want to enable OEM Unlock on your Galaxy S9 and S9+, we strongly suggest that you enable it before setting up the device with your personal data. But you didn’t be prepared for getting everything deleted from your device by taking appropriate backup already.

However, if you’ve chosen to enable OEM Unlock, later on, you’ll need to flash a specific file with TWRP custom recovery to bypass the mandatory factory reset. All you need to do is flash the DM Verity disabler using TWRP and this will ensure that all of your personal data on the device is not affected.

Do you have the OEM Unlock option visible on your Galaxy S9, or does your variant not support it at all?

  1. On my Galaxy S9, the ‘oem unlock’ option disappeared after removing the sim card. Samsung are not open source friendly. Totally locked down until the oem unlock option appears again after 7 days (after a factory reset). Make sure you sign in to your Samsung and Google accounts after a factory reset . I may as well buy an iphone. I will never buy Samsung again. Also it is worth mentioning that Samsung drivers are locked down and as a result Lineage has had issues with the mobile network dropping out. Tripping KNOX is a bad idea if this is your daily phone as you have much to lose (warranty is void, netflix, samsung pay no longer work). Also MMS messages have not been working which is a disaster when trying to open missed call messages. Bluetooth works well and is stable. The camera is good enough.

  2. That’s exactly why I dislike and never recommend Samsung to family and people : they’re just making things a PITA. Just like Apple in some way.
    I’ll stick to HTC for a very long time.
