IPhone – Can’t reset iPhone because iTunes must update the phone at the same time

iphoneitunes

I have a iPhone 6s at my work. A former colleague have quit and he have set a password to it so we can't login. This is what we've tried so far:

  • DFU mode and tried to reset to factory settings trough iTunes. Can't
    reset because of storage space is too small and iTunes is demanding
    to update the phone at the same time!
  • Tried to deactivate the phone by entering false passwords so that it
    forces the phone to reset.

So I can't reset the phone with this. Is there any other way?

Edit:

This is the message I see on the screen on the iPhone:

iPhone is deactivated – connect to iTunes

When I try connect the phone with USB in the computer I get the following error:

iTunes could not connect to the iPhone "iPhone" because it is locked
with a passcode. You must enter your passcode on the iPhone before it
can be used with iTunes.

These are the options: More Information, Try Again, Cancel

On the phone I cannot enter any passcode…

We found a solution to the problem. We logged in to our collegues computer and used his iTunes and preformed an reset and it did work.

Thanks all for all the help!
