Method 1: IT Policy Removal (Preferred)
If you have any 8xxx or 9xxx device the best method for removing IT policy is to update it to OS 4.3 or higher (if possible) and you can use JL_Cmder's "resettofactory" command to remove ALL IT policy, Firewall restrictions and Application Permission settings. After you've upgraded to OS 4.3 or higher, simply backup the device using Desktop Manager
, close Desktop Manager, then run JL_Cmder and execute the "resettofactory" command. The device will do a security wipe of the device; (meaning wipe your data but leave the OS, DO NOT use the "Wipe" command in JL_Cmder) then reboot leaving the OS, 3rd party apps but no data AND, best of all, NO IT policy whatsoever. When you're done, simply restore your backup and you're good to go with no policy or locked firewall. You can downgrade back to the old OS if you desire, too.
