TPM lockout after Imaging SP3 to windows 8
There is a flaw on the new Surface Pro 3 (shipped with windows 10), once you re-image it to windows 8, it locks out the TPM and prevents bitlocker from coming on.
Fix:
1) Clear the TPM and unencrypt the drive first, then re-image.
or
2) (Post-imaging)
Run the below command using PowerShell (run as admin) one at a time.
$tpm=get-wmiobject -class Win32_Tpm -namespace
root\cimv2\security\microsofttpm
$tpm.DisableAutoProvisioning()
$tpm.SetPhysicalPresenceRequest(22)
After reboot, you can now enable
Bitlocker.
