In this guide, we will show you the steps to enable the OEM Unlock on Samsung and hence perform an RMM State Unlock. Samsung devices are among the most active players in custom development, however, nearly every tweak performed on this device has a difference between day and night in comparison with other phones out there. And the difference starts right from the first entry point- the unlocking of the bootloader.
Every device requires you to enable the OEM Unlock toggle before unlocking the bootloader, and Samsung is no different either. However, where it differs is in the enabling of the OEM Unlock, as you cannot simply do so from the USB Debugging mode. Rather you will first have to carry out a few additional tweaks beforehand to achieve the RMM State Unlock. And in this guide, we will show you how to do just that.
Enable OEM Unlock on Samsung: RMM State Unlock
The below process will wipe off all the data from your device and could nullify its warranty as well. Moreover, Knox will be tripped too. So proceed ahead with caution. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.
First off, flash the oldest firmware available for your binary version through Odin. Regarding this, the below information shared by corsicanu will come in handy:
You can find out what bl/modem rev you have by checking the current build number of your current rom. Let’s take A520FXXU7CRL8 – in this build number 7 is the revision, leave other numbers and letters for some other time. To be able to flash older firmware it must be the same revision, or Odin will fail. Search on the firmware-related websites for older fw of your phone/region that has that same revision. So for the device mentioned before A520FXXU7CRHA is the oldest fw that can be flashed.
- Skip everything on the first boot setup including WiFi settings.
- Then enable developer options and disable automatic system updates from there as well.
- After that, connect to a WiFi network and go to Settings > Software Update, and disable Automatic Software Update.
- Now go to Date and Time settings and select the Time to be set Manually.
- Then set the date to be 10 days behind your current date.
- Now go to Developer Options and turn it off (click on the right top corner toggle)
- After that, go to Software Update and check for a manual update. Once you get an update, restart your device.
- Once the phone has rebooted, your date and time will be reset to the current time automatically.
- So go to date and time again but this time set it to be 10 days ahead. Now, check for software update once again and reboot when finished.
- After reboot, go to Date and Time and add 8 more days ahead (you should be 18 days ahead of your actual date at this point).
- Now perform a software update check once again and restart your phone.
- After the final reboot, enable Developer Options again and OEM unlock should now be available!
That’s it. These were the steps to enable the OEM Unlock on your Samsung and hence perform an RMM State Unlock. If you have any queries concerning the aforementioned steps, do let us know in the comments. We will get back to you with a solution at the earliest.
