Are you facing the missing OEM unlock issue on your Samsung Galaxy device? That’s because your phone has entered the Prenormal RMM state. However, if you’d like to bypass it, then you can follow the instructions below and fix missing OEM unlock toggle on Samsung Galaxy devices. These include the Galaxy S8/S8+, Galaxy S9/S9+, and Galaxy Note 8.
But before you get to the steps, take a look at the information below to know what RMM state actually is and how in turn, it affects the OEM unlock option.
What is Prenormal RMM State?
RMM (abbreviated for Remote Mobile Manager) state is a security functionality introduced to aid tighter theft protection by Samsung in Android Oreo. After the user finishes the Setup Wizard, the ‘RMM state‘ turns from ‘Normal‘ to ‘Prenormal‘ for a period of 7 days (168 hours). After the stated period a query is sent to Samsung, and if the phone is clean, the state will turn back to normal.
So, what does the RMM state have to do with OEM Unlock? – During the Prenormal RMM state, the system automatically disables the OEM unlock toggle intentionally. The toggle is disabled to prevent flashing of any custom binaries like firmware, custom recoveries like TWRP, root packages, etc.
If you’re going to install TWRP recovery or root your phone, you will first need to turn ON the ‘OEM unlock’ toggle in Developer options. But since the toggle would be missing (Actually ‘disabled’) in Prenormal RMM state, you would be forced to wait for a 7 days period. Thanks to XDA member altai1963 you can easily fix missing OEM unlock toggle on Samsung Galaxy devices including the S9, S8, and Note 8.

The method below has stopped working on the newer firmware released in or after August 2018. In most situations, your device will be forcibly locked and the OEM Unlock toggle will be missing. Ensure that you insert a SIM card, connect to your network, and NOT REBOOT your Galaxy device for straight 7 Days (168 Hours).
Once the RMM State turns back to ‘Normal’, you’d be able to flash custom binaries like TWRP. However, before flashing, make sure to read our article on how to Prevent Prenormal RMM State and avoid your device from being locked again.
