I have a Nokia Lumia 930 which has a broken screen.

I want to perform backup but my computer doesn't recognize the phone over USB.

How can I backup my phone?

Thank you


Before I can answer, I need to know exact status of the broken screen?

  1. Display working & Touch Not working
  2. Nothing is working (I guess that might be the case)

EDIT: Ahh! I missed that possibility. Anyways,If you've PIN enabled then it adds one more target to be shot in the dark.

  1. Connect your phone to PC via USB.

    (Since it is locked you can't access the storage. But if recognized by PC in File explorer, then it confirms that all else is working fine, probably)

But locked phone won't let you access to storage via PC. So you need to unlock it.Try to guess on the broken display- the unlocking procedure

i.e.: Swipe up. Assuming numpad keys, type-in the PIN. Hope this unlocks the phone.


You can use a cello-tape to cover the screen & protect damage to your hand & this also keeps broken glass.

Also, you can print an image (match display & print size) of numpad for reference. Roughly position it onto the broken display & try to unlock the phone. Now you can copy your data from phone storage to your PC via File explorer. Hope this helps! o enter image description here

It may not help in backing-up everything. So you can also try Project my screen to view the contents on your PC screen. And You can pretty much backup everything then. Here, you can use touch on your phone. (Works if phone is unlocked and phone has Windows Phone 8.1 OS on it). I guess 'Connect' feature does the job in W10 Mobile for screen projection. You can ask cortana for that. It'll be great if this works.

(I'm currently checking screen projection to PC from my Lumia 1020 having W10 Mobile, I will add updates soon)

Project my screen

  • The display is not working while the touch screen does (at least seems: it vibrates when touching the back, windows and search keys)

  • Also, if later you find touch not working properly (happens). You can try using mouse via OTG.
