Does anyone have some tool to change ServiceTag on DELL Latitude 5300? I can contribute some $$ if needed.
PlatformConfig64.exe is probably the tool but it won't let you change the service tag unless you are inside Dell's manufacturing network.
See my answer above. I posted a link to the tool in the BIOS Tools thread a while ago but as mentioned you can’t change your service tag with the tool unless you’re inside Dell’s network. You have to unlock some sort of manufacturing mode first.
