Problem
You are unable to use the device after factory reset since you need the previous account.
Environment
- Android Device Management
Solution
The way you set the Factory Reset Protection policy, is the following:
- On the Admin console, go to Devices > Mobile and endpoints > Settings > Android Settings.
- Once there, you will find the policy under Device Features.
- There, you must add the list of administrators you want to use in scenarios like this.
- If this wasn't set, you will need to reach the manufacturer to request the protection lock to be removed.
Cause
Because the factory reset protection is a feature built within Android itself and is not controlled by the Admin console.
