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 2.5, if your UI version is something else slight difference maybe there).

3. Once done you need to download the firmware files and the Odin app.

Please download the Android 12 firmware corresponding to your phone using the below links;

Same way click on "AP" and and select the extracted firmware file which starts with "AP". Similarly, add BL file in the BL button.
If you want to factory reset while you download and install stock firmware select "CSC" file after you click the CSC button, otherwise, load the "HOME_CSC" instead.

Ignore the last button on Odin which is "UMS" or "USERDATA".
