#WP7 : LG Optimus 7 Unlock + Interop Unlock + Root Tools


If you want install XAP files without a developer account you can do it by modifying some registry keys:

  1. First go to MFG and follow the path 7.Engineer Menu > 6.Other Settings > Edit Registry
  2. Set the following fields:
    • Select ROOT_PATH: HKEY_LOCAL_MACHINE
    • Input SUB_PATH: Comm\Security\LVMod
    • Input KEY and Select data type:  DeveloperUnlockState   DWORD
    • Input data: 1
  3. Click Set button

To avoid Zune undo to default settings:

  1. Go to MFG and follow the path 7.Engineer Menu > 6.Other Settings > Edit Registry
  2. Set the following fields:
    • Select ROOT_PATH: HKEY_LOCAL_MACHINE
    • Input SUB_PATH: Software\Microsoft\DeviceReg
    • Input KEY and Select data type: PortalUrlProd   DWORD
    • Input data: leave this field empty
  3. Click Set button

  2. Set the following fields:
    • Select ROOT_PATH: HKEY_LOCAL_MACHINE

From now on your device is unlocked in developer mode, but you cannot install homebrew apps that modify registry keys. You need Interop Unlock:

    • Input SUB_PATH: Software\Microsoft\DeviceReg\Install
    • Input KEY and Select data type: MaxUnsignedApp   DWORD
    • Input data: 300
  3. Click Set button

NOTE2: Unlock & Interop Unlock works on WP7 Tango too.

NOTE3: to lock device again set DeveloperUnlockState to 0 (zero).
