MDM does not allow factoryReset 해결법(공장초기화 안될 때)

Okay so here is a little back story. I work in an IT department and my company loves anything VMWare produces so they use Airwatch for work emails on mobile devices. Airwatch has it's on MDM and provides security for the device in case it ever gets stolen which is awesome, but I had a specific case where the customer had the awesome idea to turn off his wifi internally (can't use airwatch console to remote wipe), and forgot his encryption password and I was like great... So I tried factory resetting it and lo and behold I get the infamous message "MDM does not allow factoryReset"... This is obviously a part of Airwatch's MDM control so someone can't just factory reset a device and claim it as theirs. I know a lot of people recommend Odin and just flash it with another ROM version, but that isn't "company standard" so it's not very advised to do that. So I put my superior IT knowledge to the test and imlemented a grand strategy to fix this.

Alright so for everyone who has this problem you are going to want to follow these steps...

1. Set a password for the device
2. Make sure the device has 80% charge or more
3. Settings -> Security -> Encrypt Device

Now once you have encrypted your device and it has went all the way through. Reboot the device and now on bootup it should ask you for a password to get into your device to see encrypted data. Get this password wrong 15 times (can vary from device) and it will wipe the device clean of any data and it will reboot, then come up as if you're registering a new device from factory reset. I know this solution is a bit caveman status, but it works. Hope this helps!

 

갤럭시S4에서 실험해봤습니다.

1. 설정 > 보안 에서 비밀번호를 설정한다.

2. 충분히 배터리를 충전해놓은뒤 다시 켠다.(작업이 약간 걸린다)

3. 비밀번호를 치라고 하는데 계속 틀리다보면 몇 번 더 틀리면 정보가 삭제된다고 협박한다.

4. 바라던 바이니 그 횟수만큼 틀리고 초기화한다.
