how to add UDID in new system

Question

Earlier I use to follow below steps to add UDID in my profile using below link.

http://www.wikihow.com/Add-a-New-Device-to-Your-Apple-Developer-Portal

I have app where I send client the updated provision file after adding UDID that client send to me so that I don't had to ask to come with iPhone at my place.

Now when I login to developer account, I see Add button as disabled.

Is there any way where I can add UDID in my device list without having iPhone with me?

Note:

I have filled only 28 UDID and 72 is still pending.

Is it because I added some iPhone through xcode and downloaded new provision profile through xcode only?

Below you can see the Add button disabled.

Answer 1

That just happened to me. I just had to reset the device list.

Click on the Get Started button and remove any device you don't use anymore. When you finish, the + button will be enabled again
