How to Enable USB Mass Storage Mode in Nokia Lumia 800

Before starting we want to tell you that according to original founder of this hack Nokiabuff.com this will work for Music & Video but any music files transferred are grouped under “Unkown Album”. Techstic.com also confirm one thing that we have not actually tried this method to enable USB Mass Storage Mode due to non-availability of Nokia Lumia 800 here. If you still want to apply this method read below:

1. Open Windows Registry Editor by typing “ regedit ” in start bar or in Run tool.
2. In the Left Pane click on HKEY_LOCAL_MACHINE
3. Then find SYSTEM folder in the tree and click on it
4. Then under SYSTEM folder open folder tree CurrentControlSet  >> Enum >> USB.
5. Now Select USB folder
6. Then Search for “ZuneDriver” by pressing Ctrl+F keys or by clicking Find in Edit Menu at the Main Menu Bar (USB folder should be Selected before searching)
7. It will find “ZuneDriver” under VID_045E&PID_04EC&MI_00 folder tree
8. Now click on Device Parameters folder tree, then right click on Device Parameters and click Export in case if something goes wrong, it will restore the registry to old state
9. Now click on Device Parameters, and it will shows all registry values under it in right pane.
10. Now in the right pane double-click the registry value called ShowInShell and change its value from 0 to 1
11. Then double-click the registry value called PortableDeviceNameSpaceExcludeFromShell and change its value from 1 to 0
12. Then double-click the registry value called EnableLegacySupport from 0 to 1
13. After changing above three values, close the registry editor and it will save those values.
14. Now Remove the Nokia Lumia 800 USB connection and re-insert it again.
15. You will see two portable devices displayed in My Computer with a Storage capacity of  13.3 GB.
16. Now you are able to transfer your Music, Images and Videos to the Lumia without using Zune Software.
17. Dont forget to eject device before removing the USB cable otherwise it may create issues.

As we already mentioned that the music added via this hack will show as unknown album in Music app. Although in LovemyNokia.com test the picture and video transfers to the device worked without any problem.

But you should copy the compatible formats to play in Nokia Lumia 800. This hack is much faster then Zune as you can see the files pop up in Lumia gallery or video player as you begin to transfer in picture.
We have to conduct test whether this hack works without Zune, as source images shows  that after removing the Zune, Lumia 800 still managed to get drivers from Internet and LoveMyNokia blog guys  had to reapply this registry hack to enable it to show in My Computer. And the file transfers worked fine too.
