what most people miss is that once the correct SP file is run it creates a folder on the c drive with the necessary update files
you MUST open a DOS shell (not powershell) and change to that created folder using the "CD" command once in the folder read the included doc file on which bat file to use to start the update the updater will select the correct files needed to update DO NOT TRY TO MANUALLY FORCE A UPDATE as selecting the wrong update file will kill the tpm chip
also, if you try to just dbl click on the update's bat file it will just open and then immediately close a dos window without running the updater's bat file
last, there is a hard limit on the number of firmare flashes the tpm chip will take (it's over 10 but less than 50 as i recall)
