iTunes could not connect to this iPhone. The value is missing.

Hold down the power and the home button until the phone reboots to show the itunes logo.

Uninstall itunes, uninstall apple mobile device support. Reinstall iTunes and plug the phone back in to update once more.

What version of iTunes is running on our computer (an actual version number, not "the latest version")?

connect charger with laptop. hard press both home and power button until you see iTunes icon on phone. you will restore and update selection. if you had back up on iCloud. restore it to factory setting.

After trying the home/power button combo about a dozen times and each time coming up the the "iTunes could not connect to this iPhone. The value it missing." message, I did one thing different and it worked.

With my iPhone connected to my computer I did the reset until the iTunes logo came up, in iTunes it gave me two options in an alert/dialog box, if I wanted to "Update" or "Restore", I clicked restore. Then in another alert/dialog box it would ask me "Are you sure?" kind of thing. The first dozen times I continued, and it would do nothing. The last time however I clicked "Cancel" and then then clicked the Restore option that was in the iTunes application window. It then asked me again "Are you sure?" This time I clicked "Restore" (or whatever, not exactly sure, but I confirmed), and viola! it did it's thing!

Hope this helps.

Did you try just the update or a restore to factory settings?

Dude. I totally smashed my iPhone and needed to reset it so that I can send it back to the insurance company. What I could see on the screen is that it was in lock mode and was counting down. I held the home and lock buttons down for about 20 sec or so and iTunes finally recognized it. This was the most help in the tread. Cheers!

Any new answers for this? My daughter's phone 5 is disabled due to kids mucking about with the passcode. Now i get this 'value missing' error message no matter what I do. Never gives an option to restore. I'm on iTunes 12.7.0.166 (mac). Over 2200 people on this thread have the same question - Apple should get their finger out.

I have done this many times, it still says "iTunes could not connect to this iPhone. The value is missing." and even the iTunes logo doesnt even pop up when press the power button and the home button! What should I do next?

Regards,

Dan

USE AN APPLE BRANDED LIGHTNING CABLE OR YOU ARE WASTING YOUR TIME

Non-Apple lightning cables will not work for a restore. Connect device to Mac/PC, Hold down home and power buttons to boot device into recovery mode, select restore or update from iTunes. Follow instructions on screen.

I've tried to resolve this using the tips from the community for an iPhone 7 that's locked in disable mode and when we go into iTunes as suggested the "cannot connect...missing a value" box continues to come up. Never have had this before and must have phone today - genius bar appointments unavailable... please advise

Thanks Brian! After trying everything out there that I read, your method worked for me!

Have iTunes open and then connect phone. For my iPhone 7 plus I had to hold the home button, the power button, and then the volume down for the restore screen to show. Then iTunes prompted me to update or restore. As Brian mentioned you hit restore then it will ask you are you sure hit cancel and then you should see that the iTunes options for update and restore are no longer greyed out and you can select restore and your phone should start processing.

BEWARE that it will erase everything on your phone but if you have a backup on iTunes or iCloud you should be good. Thankfully I had set my phone to back up on it's own 😊

If you have a new iphone make sure you are holding thenvolume down button, the power button, and the home button and hold all three until the restore screen shows (make sure you are connected to a computer to itunes while doing this)
