Surface Pro MDT Install

Question

Have been struggling for a while to get a Surface Pro 3 to install using MDT, PXE boots OK but installation ends with an error relating to the unattend.xml file.  Looking at the setuperr log on the device the error is described thus:
2015-03-05 07:53:52, Error                        [setup.exe] SMI data results dump: Source = Name: Microsoft-Windows-Shell-Setup, Language:
neutral, ProcessorArchitecture: amd64, PublicKeyToken: 31bf3856ad364e35, VersionScope: nonSxS, /settings/ComputerName
2015-03-05 07:53:52, Error                        [setup.exe] SMI data results dump: Description = Value is invalid.
Eventually worked out that this is related to the length of the serial number on the Surface Pro 3, we use the serial number in MDT to create the Computername.  as this must be 15 characters or less the use of the Surface Pro 3 serial number breaks
this rule when we use our custom computername string WSERC%SerialNumber%, this had worked for ages as we've only installed Dell machines with a 6 digit service tag as the serial number.
Fixed this using the following string WSERC#right("%SerialNumber%",10)#
Surface Pro 3 now installs OK with MDT.

Hi,
Have you follow that guide to check key points?
When you add the driver under Out-Of-Box Drivers for Surface pro, note the last folder must be called “Surface Pro”. If it's for Surface pro 2. it should be the "Surface Pro 2" folder name.   If your Out-Of-Box drivers contain drivers
for other systems and you do not use one of the options in that guide. Then you cannot control what drivers get used during the deployment. This can lead to problems so we would recommend you use Selection Profiles or other methods to ensure only the drivers
designed for the Surface are used during the deployment.
For additional reading on this topic I encourage you to take a look at
this blog.
In addition, you also could consider to use a USB drive to update the firmware offline:
