Problem setting up new IPhone SE from manual backup in itunes
I have a new iphone SE and I'm trying to set it up for the first time with a backup from my iphone 5. (i know, ancient technology) I'm using a manual backup in itunes. I have Mojave OS. My new phone had a glitch in the original setup—I got an error message saying there was not enough room on the phone for the backup. (what happened is that it was automatically syncing my music library-which I don't want it to do, I usually only do a playlist).
So I had to pull the plug and stop the setup.
Now when I plug it in I don't get the welcome screen anymore on my Mac. I did have the setup screen still (hello!) on the iphone SE. I tried to do through a backup but it doesn't see the old backup in my itunes. It says no backup. But then, if I plug in my old iphone the backup is still there.
So I set it up without a backup, hoping to factory reset and that maybe I could start over.
I thought factory resetting it using "transfer to a new iphone" would help. But its only made for using the iphone SE as the old iphone and using icloud.
Is it possible at this point to set up my new iphone using the manual backup from my iphone 5, or am I stuck at this point with it the way it is?
Thanks so much!
iPhone SE
