[Samsung Galaxy S10e Questions & Answers] laoshoe:
Even after 7 days uptime without a SIM card the KG state was still "Prenormal" so I decided to disable a bunch of Google/Samsung services and insert a SIM card. After I did that the KG state has changed to "Checking" (whatever that is) and I am able to see the "OEM Unlocking" option in the dev menu. However I am currently unable to actually flash a ROM and the OEM lock status still says "ON" in Download Mode. So it's not 100% solved but it's an improvement.

Link to my new topic discussing this new problem: https://xdaforums.com/galaxy-s10e/help/oem-unlocking-activated-menu-download-t3948060

Here are the packages I disabled before inserting a SIM:
