[XAP][SOURCE] WP8 Registry Tools

snickler · Aug 6, 2013

Rebranded to WP8 Registry Tools from Lumia Registry Modifier

This is a basic registry viewer/editor demonstration using Registry dlls pulled from Nokia xaps within the latest FFUs.

First, a few things to note.

1) This only retrieves values from HKEY_LOCAL_MACHINE
2) It CAN read DWORD values now, but can't write. (Hell you probably won't be able to write ANYWHERE, but the code is there)

Instructions are quite simple.

To Read Values:

1) Put the Registry key in the first box (ex. SOFTWARE\Classes\MIME\Database\Codepage\1254
2) Put the Registry Value in the second box (ex. 1254)
3) Press Get Value.

To Set Values:

1) Put the Registry key in the first box (ex. SOFTWARE\Classes\MIME\Database\Codepage\1254
2) Put the Registry Value in the second box (ex. 1254)
3) Put the new registry value result in the Set Value box.
4) Press Set Value.

This is very very basic, but I wanted to just show off something using what Nokia has provided us.

We can't write dword values unfortunately so hopes of using this to change the MaxUnsignedApp value are lost. This MAY be possible with @GoodDayToDie 's WP8NativeAccess library, but with this it isn't.

In case everyone wondered what that key is... SOFTWARE\Microsoft\DeviceReg\Install

Side load away

Hmm... I get Access Denied in my library on most keys that I've tried to write. If you can write the codepage, that's interesting (generally speaking, HKLM has stronger protections). I'll double-check whether I can write there myself. If not, but you can, then we have an elevated privilege attack vector...

Also, we should see whether the app runs on non-Nokia devices. I suspect that it will, if it works the way I think it does, but in that case it also won't have much in the way of permissions.

Getting DWORDs to work is a good project, I'm sure it's possible (works fine in NativeAccess, incidentally).

EDIT: Any chance you could include the source?

ah yes, sorry about that. Let me load up my laptop

Hi I found the Registry item
(File path : <ffu>\Windows\Packages\RegistryFiles\SOFTWARE.REG)

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\KindMap

where we can set extensions and their types.so is it possible to add a new extension so that it will also be supported and visible in sdcard ?

It doesn't support creating new key values, only modifying existing ones. If the data is within one key value and it's able to be read, then it should be able to have things added to it.

EDIT: From what I've seen, what you're trying to do won't be possible with this. Each extension has a different key value.

We may need to start an "interesting registry values" thread here, similar to the one for WP7. Of course, it'll be more interesting if we can actually change any of them.

Oh, and the app works on my ATIV S, just by the way. Need to find some interesting paths to test it on, though.

EDIT: Have you been able to write to *any* values using this? It fails for me every time, but I haven't tried that many yet.

it has failed for me also. The only values I could write to were the ones that corresponded to Nokia. I'll look through the code again and make another update. I'm going to also rebrand it since it works for non Lumia phones.

GoodDayToDie · Aug 7, 2013

Interesting about the Nokia paths working. That could be some characteristic of the DLL you use having better permissions or something specific to OEM stuff, but I actually suspect it's just that Nokia didn't bother to lock down the ACLs on their parts of the registry. You can easily adapt the app to my NativeRegistry class to test this, if you want.

snickler · Aug 7, 2013

Hmm that's a good idea. I just rebranded it to WP8 Registry Modifier. I'll add in your NativeRegistry class to work along with the RegistryRT class to see what comes about.

DWORD support

For DWORD support, take a look at the Nokia.SilentInstaller.Runtime.wim... The "CSilentInstallerRuntime" class contains multiple methods to interact with the registry including:

CreateKey
GetRegDWORDValue
GetRegSZValue
GetRegSZValueL
IsRegistryDWORDValueExists
IsRegistryKeyExists
IsRegistryREGSZValueExists
SetRegDWORDValue
SetRegSZValue

A bit off topic, I found a way to launch any URI... Literally, ANY URI (app:// http:// or anything). I can launch any application (using the GUID - so it must be a registered application but doesn't have to be one that you see in your programs list) and go to a specific page within that application. I can also pass any kind of query string that could unlock some hidden features in an application (such as the Extras+Info application - I can launch it using any dial string even though my ROM has that particular dial string disabled). I do so by launching a Toast message which allows me specify a launch uri and once it pops up, I click it. If anyone's interested, I can post a code sample for that...

snickler · Aug 7, 2013

@GoodDayToDie I'm able to read DWORDs with your NativeRegistry framework. I haven't been able to write though (I've only looked at the MaxUnsignedApp reg value).

What I think I'm going to do is possibly scrap the RegistryRT framework and just use yours. I can then make an even more robust app.

I was actually looking at the SilentInstaller not long ago. I got sidetracked by the fact that I could use the NativeRegistry read DWORD values. I'll check that out and upload a new build in a few

I can write one up later. I have several registry keys that I'd like to bring attention to.

NOTE: I don't see anything editable yet, at least I can read it to compare it to the files in the ffu.

GoodDayToDie · Aug 7, 2013

Launching a URI should be possible more directly than that, using ShellExecute, or similar, but that way is cool (and doesn't require importing unofficial native functionality).

Just a word of warning: NativeRegistry is under heavy modification. I hope to have the next Alpha release done soon, which brings a ton of changes, but in the meantime you might want to follow the changes on CodePlex; while I test every build that I push, I don't always publish the binaries.

There will be two ways to use the registry through NativeAccess soon: one is to use fairly thin wrappers around the native functions (that's mostly what's implemented now, but it will be expanded to include key and value enumeration, key creation, etc.), and the other is to use a class more akin to a .NET RegistryKey class, offering the ability to interact in a more object-oriented manner (where the object itself represents an open key).

Something I did notice when I tried to compile the NativeRegistry source (I just ended up using the binary you had for my testing) is that it kept blowing up on the include for WinReg.h. I don't have that anywhere. Am I missing something?

I'm not sure how GoodDayToDie did it himself (probably same approach I take it) but I compiled it using the "WinReg.h" from the Windows 8 SDK and removing the desktop-only compiler "if" instruction (lines 49 and 1446). And like he mentioned, you also have to create the KERNALBASE.LIB with the required registry export functions for the linker.

Ah ok, thanks!

Yes, please post your code and give yourself your own thread (at least keep it here in development

). There are a lot of underlying dialer codes that Nokia disabled when flashing the 928s. Also this could mean we could have a custom app launcher, if you wanted to customize it that way. Most of the work we have done on WP8 has occurred in the past few months; we are finally getting so close to the first InteropUnlock for Nokia/WP8.

I'm trying to figure out the correct method prototype (since this is a method that appears to be WinPhone only and isn't part of the SDK so, no details on it whatsoever)... I stumbled upon this toast functionality in "NokiaFrameworkOBAWinPRT.dll" under the "DevPropHelper" class. The method to call is "InvokeToast". This method ends up calling "Shell_PostMessageToast" in "ShellChromeAPI.dll" (this is what I'm trying to invoke directly without going through the Nokia dll).

Add a reference in your project to "NokiaFrameworkOBAWinPRT.winmd" (you can find this in newer versions of the Extras+Info app)
Add the necessary <InProcessServer> tag (to allow the "NokiaFrameworkOBAWinPRT.DevPropHelper" class) in the <ActivatableClasses> section of you WMAppManifest.xml file
In the code... Create an instance of "NokiaFrameworkOBAWinPRT.DevPropHelper"
In the code... Call the "InvokeToast" method (of the previously created object) passing it:
- Application GUID (can be your local app's GUID - doesn't seem to matter)
- URI to launch in string format
- Toast title (can be anything)
- Toast content(can be anything)

When the Toast notification pops up, click on it and that's it.
