[Windows Phone 7 General] jlott069:
I was just looking for some opinions... It seems to me that out of all the WP7 Devices, the LG Quantum is the easiest to make changes to simply because of MFG.

Debranding and unlocks take just a couple of seconds and seem to be more reliable when I look at all the different posts on here. Incase anyone is looking for them for the quantum, here they are btw...

LG "debranding" hack

1. Enable the MFG application by going to the dialer and dialing ##634# then pressing call.

2. Launch the MFG application and enter 277634#*# when prompted for a password.

3. Select the Engineer Menu item.

4. Select the Other Setting menu item.

5. Select the Edit registry menu item.

6. Set the input boxes on this menu as follows:

Select ROOT_PATH: HKEY_LOCAL_MACHINE

Input SUB_PATH: \System\Platform\DeviceTargetingInfo\

Input KEY: MobileOperator

Data Type: STRING

Instead of putting in a blank, put in an empty space.

Also, if you want to re-brand your phone after the update for AT&T your input should be ATT-US

7. Select Query and write down the result in case you need to re-brand for some reason.

8. To debrand just enter the same information above and leave the input data field blank. The tool will say fail but it really did set correctly.

You can now connect to Zune and check for updates.

How to Un-Lock your Phone without Chevron 7

You can unlock the phone by using the MFG registry editor.

Open the MFG app and use the password to open it. If you don't know it's (appmfg#*#)

Go to Engineer Menu -> Other Settings -> Edit Registry

Set your ROOT PATH to "HKEY_LOCAL_MACHINE"

Set your input path to "\Comm\Security\LVMod"

Set your input key to "DeveloperUnlockState" and set to DWORD

Hit Query. Output result should return a "0" or a random long number. If it does continue.

Set your input data box to "1" and hit SET. Output result should be 1

How To Keep Your Phone Unlocked

You can keep your phone unlocked and prevent Zune from re-locking it.

Open the MFG app and use the password to open it. If you don't know it's (appmfg#*#)

Go to Engineer Menu -> Other Settings -> Edit Registry

Set your ROOT PATH to "HKEY_LOCAL_MACHINE"

Set your input path to "\Software\Microsoft\DeviceReg"

Set your input key to "PortalUrlProd" and set to DWORD

Hit Query. Output result should return data. If it does continue.

Keep your input data box empty and hit SET. Output result should be 0

Keep this screen open and continue to Part 2

Part 2

Set your ROOT PATH to "HKEY_LOCAL_MACHINE"

Set your input path to "\Software\Microsoft\DeviceReg"

Set your input key to "PortalUrlInt" and set to DWORD

Hit Query. Output result should return data. If it does continue.

Keep your input data box empty and hit SET. Output result should be 0

Backout to the password screen and shutdown the phone via powerbutton.

Reboot and sync. Your phone should stay unlocked.

How to Re-Lock your Phone without Chevron 7

Don't want your phone unlocked anymore? You can re-lock the phone by using the MFG registry editor.

Open the MFG app and use the password to open it. If you don't know it's (appmfg#*#)

Go to Engineer Menu -> Other Settings -> Edit Registry

Set your ROOT PATH to "HKEY_LOCAL_MACHINE"

Set your input path to "\Comm\Security\LVMod"

Set your input key to "DeveloperUnlockState" and set to DWORD

Hit Query. Output result should return a "1". If it does continue.

Set your input data box to "0" and hit SET. Output result should be 0

Your phone is now locked. To Unlock the phone redo the above steps but set back to "1"

Oh and I can confirm this unlock method works and keeps it unlocked.

Then once unlocked, if you combine it with the Chevron ringtone manager-> http://www.chevronwp7.com/post/20542...ngtone-manager, and any registry changes you know of such as changing themes and such, there really doesn't seem to be much you cant do with it. Is my opinion accurate? Or is it just skewed because I love this phone? Also, is the MFG the reason why it doesn't seem like anyone has worked on software for the phone like they have with the Samsung and HTC models?
