So what does updating drivers in your recovery image do?
– Resolves the “Unknown device” issue, permanently
– Known to resolve some instances where the Surface Pro 2 crashes upon resume
– Wonderful for perfectionists. Having the latest drivers when your Surface Pro 2 boots for the first time makes you feel warm and fuzzy
Microsoft have done a fantastic job with the Surface Pro 2 (best gadget I’ve purchased in years) but nothing is flawless and Surface Pro 2 is no exception. If you perform a reset on your Surface Pro 2 you will notice in Device Manager that there is an “Unknown Device”. As you probably know the “Unknown Device” is the “Surface Cover Telemetry” device.
After some investigation I found that the recovery image itself does not contain the driver for this device. Ooops! Some people have found a temporary solution by manually installing the driver right after a reset before any Windows Updates are run but you’re going to run into the same situation again when you perform another reset on your Surface Pro 2. I’m sure Microsoft will release a hotfix for this problem in the near future however, that hotfix will not fix the recovery image itself.
If we compare the Windows drivers repository (C:\Windows\System32\DriverStore\FileRepository) on the original recovery image against a Surface Pro 2 that has the driver installed we can see straight away that the Surface Cover Telemetry driver files are missing.
FAQ (I’ll add more FAQ’s when the questions start coming through)
Question: Do I lose my original Recovery Image that is shipped with the Surface Pro2?
Answer: No, this image is backed up and can be restored
Question: Can I still run the firmware updates from Windows Update
Answer: Yes, you can run ALL the available Windows Updates when you have finished resetting your Surface Pro 2
Question: Will this work on the original Surface Pro?
Answer: I don’t see why not, however I have not tried
Question: Will the recovery partition on my Surface Pro 2 be updated with the new recovery image when I use the USB stick?
– Windows 8.1 (RTM\GA) so we can use the correct version of DISM.exe
– 8GB USB stick
– Surface Pro 2 driver pack (http://www.microsoft.com/en-au/download/details.aspx?id=40856)
Step 1: Create a USB recovery drive using your 8GB USB stick (I prefer not to delete the recovery partition)
Step 2. Create some temporary directories to perform all our work in
Hit Start + X and select “Command Prompt (Admin)” then run the following commands
Step 3. Now using your favourite zip program extract October2013SurfacePro2.zip to C:\Temp\SP2Recovery\Drivers
Step 4. Copy the source image files to your computer where “E:” is the letter of your recovery USB stick
copy E:\sources\install*.swm C:\Temp\SP2Recovery\Source
Step 5. The recovery WIM image is split into multiple images on the USB recovery stick because the USB stick is formatted as FAT32. FAT32 has a file size limit of 4GB and the recovery image is over 5GB
Split WIM images have the extension SWM. Since we can’t mount SWM image files we’re going to merge them together to create a single WIM file for mounting
DISM /Export-Image /SourceImageFile:C:\Temp\SP2Recovery\Source\install.swm /swmfile:C:\Temp\SP2Recovery\Source\install*.swm /SourceIndex:1 /DestinationImageFile:C:\Temp\SP2Recovery\Destination\install.wim
Step 6. Time to mount the merged WIM image for editing
DISM /mount-wim /WIMFile:C:\Temp\SP2Recovery\Destination\install.wim /index:1 /MountDir:C:\Temp\SP2Recovery\Mount
Step 7. Let’s import the new drivers into the image
DISM /Image:C:\Temp\SP2Recovery\Mount /add-driver /driver:C:\Temp\SP2Recovery\Drivers /Recurse
Step 8. Save the changes and unmount the image
Note: Do not have any Windows Explorer windows open or Command Prompts on C:\Temp\SP2Recovery\Mount else DISM will not be able to close the image
DISM /Unmount-wim /mountdir:C:\Temp\SP2Recovery\Mount /Commit
Step 9. Split the WIM image into multiple parts so that it can fit on the FAT32 USB stick
DISM /Split-Image /ImageFile:C:\Temp\SP2Recovery\Destination\install.wim /SWMFile:C:\Temp\SP2Recovery\Destination\install.swm /FileSize:2048
Step 10. Copy the new split image files back to the Surface Pro 2 Recovery USB stick and overwrite the old files
copy C:\Temp\SP2Recovery\Destination\install*.swm E:\sources /y
Step 11. Time to reset your Surface Pro 2 and use that new USB recovery image.
Make sure you backup all your data and don’t forget to backup the original split images in C:\Temp\SP2Recovery\Source in case you want to use original image some day.
1. Shutdown your Surface Pro 2 (Start X -> Shutdown or sign out -> Shutdown)
2. Plug in your USB recovery stick
3. Hold the volume down (-) button and push the power button (don’t release the volume down button until you see the “Surface” wording on the screen)
4. Select your language
5. Select your keyboard layout
6. Select “Troubleshoot”
7. Select “Reset your PC”
8. Select your OS
9. Select “Next”
10. Select “Yes, repartition the drives”
11. Select “Just remove my files”
12. Select “Reset”
and we’re Finished!
Enjoy a beautiful looking Device Manager
I want the original recovery image back!
Simple! Just copy the original split image back to the USB stick where E: is your USB stick drive letter and perform a reset on your Surface Pro 2
copy C:\Temp\SP2Recovery\Source\install*.swm E:\sources
Thanks for the instructions. I did all the above and it did clean up the error on drivers when refreshing…unfortunately it did not solve the Kernel-Power issue when going to sleep mode and causing a reboot.
I can actually confirm that it looks like the Sleep power issues are solved by turning off the “Allow the computer to turn off this device to save power” setting on the Marvell Wireless controller
Is there a way to copy this updated restore image back to the recovery partition on the surface itself? We have multiple Surface Pro 2’s and I would like to just update them all and then forget it. We have the 512GB devices so we are not concerned with space savings. Please let me know. Thanks for your time.
Okay I just realized my previous question was answered in the FAQ section. However I have another question. Can the Windows key be updated in the recovery partition with my enterprise key? That way I can create one USB recovery disk and then update all of our Surface Pro 2’s.
Hi Shawn, unfortunately you cannot update the key in the recovery image because the key actually resides in the BIOS of the Surface.
Thanks for the quick response. I know in the past I have written scripts to update the bios on dell laptops, do you know if the key is updateable in the bios, via an WMI script or another way? Thanks again for the information.
I haven’t investigated this but you could try the solution here http://www.optimizemswindows.com/the-product-key-entered-does-not-match-any-of-the-windows-image/
Does this wipe your device (all installed programs and personal files gone)?
Yes, this will wipe everything on your device so be sure to backup everything before performing the steps.
These instructions worked perfect!! Thank you..
The only thing I ran into was that at the end I received a screen from the bios American Megatrends basically telling me to choose activate, clear, re activate the TPM chip by pressing PF12 or continue without changes by pressing ESC. I chose to press ESC and continue without changes and it worked well. I think the other option would cause Bit Locker to activate. Not sure. Just wanted to put this out there as it took me by surprise..
Thanks again.. Very well written!
Thank you so much for this wonderful step-by-step guide!
Great article, well worth the effort to fix the recovery image once and for all!!
Thanks! nice, easy to foll0w, and well laid out.
