Stuck in activation lock after DFU restore
No good. Because Activation Lock is server side, it is cross referenced to the system used to do the swaps and blocks any kind of repair or swap until you sign into iCloud.com and remove the lock. Can't remove it, they have to deny service. 100% of the time. No way for a manager to override it.
I find this hard to believe. There are plenty of legit reasons why a phone may need repair and you're saying if the owner can't deactivate activation lock they're out of luck?
