l*******@gmail.com cannot be used to activate this iPhone
I recently tried to update my iPhone from iOS7 to iOS8, but in the process the update failed, and it asked me to recover the phone instead. I did so but now it won't let me use my account to log in. I get the error "l******@gmail.com cannot be used to activate this iPhone" even though that is the account they suggest I use in the description above. I called Apple Support and they told me to go into my iCloud account and delete my iPhone from Find My Phone but nothing happened. Now my iPhone is linked to an account that doesn't recognize it and I can't find a way to get around it. Please help.
iPhone 4S
