The conclusion is, it is still no working no matter if the phone software shows unknown or otherwise.
You tab will boot if your take out your simcard during the tab in ON condition. Its same condition if your sim card started to fail or broken, it will also reboot since its consider there is no sim card. Its normal condition with all smartphone/tablet.
