Steps To Install Stock ROM/Firmware On Samsung Galaxy S20, S20+, S20 Ultra & S20 5G Using Odin

1. First you need to download and install the Samsung USB drivers. You can do that it from the below link;

To enable “Developer Options” on your Galaxy Smartphone goto Settings>About phone>Software Information, and tap on the “Build number” 10 times until you get a message that you are a “developer.”. Now you will see an additional menu entry in the “Settings” menu called “Developer Options” as shown below.

Once you have enabled the “Developer Options” tap on it and you will see a similar screen as shown below (These are from One UI 1.5, if your UI version is something else slight difference maybe there).

Now tap on “OEM unlocking” and “USB debugging” to enable it. If  you get a popup warning, tap enable if you would like to proceed.

In some cases after “OEM unlocking” is enabled you may need to unlock the “Bootloader” also. Please try the below tutorial if you get a failed message in Odin;
