Samsung Registry and File System Access?

RustyGrom · Jan 15, 2011

I'm getting sick of seeing all the HTC and LG guys having all the fun. Trying to do something about it. xboxmod posted this in another thread...

xboxmod said:
For now the only possible door is this registry key.

[HKEY_LOCAL_MACHINE\Software\Microsoft\FieldTest]
"ManufacturingProvXmlPath"="\\windows\\DiagnosisAp p_1.provxml"

if we can identify when it's called and by what.
possibly
FieldTestApp.exe
DiagnosisApp.xap

Sooo I've done some mucking around with this. Made a little progress but not much.

That provxml is executed every time you dial "##634#". It just installs the Diagnosis app. Whatever process is actually doing this then launches Diagnosis which is just a silverlight app.

I can write to that registry key and put in whatever path I want. The problem is, whenver I try to run it with a provxml that I've deployed to the rigtones folder or to the app's install folder it does nothing. I was able to get it to launch the provxml that installs the AT&T crapware so I know it is working after it's modified, I just can't convince it to run one that's not in \windows\. I tried emailing the file and saving the attachment (took some tricking) and that didn't work either.

Is there any way to write files to \windows\ on samsung devices? If I'm not mistaken we don't have permission to do that from SL and there's no "WriteFile" function thrown in the drivers that we know of.

Anyone have any ideas? Anything else I should try?

so...what you're saying...is that mfg is launched provxml is written...
is it possible to dump the samsung rom to pull the xap and sideload it that way...edit the xap with the new provxml so it installs on ##634# assuming mfg is an installable app
I know it is installable I have it on my phone I dunno where I got it though...if it works...
that just leaves dell being late to the party as usual...

I think you're confused. I don't think there is a XAP that installs the provxml. It's just sitting in \windows (which I don't think we have write access too) and the phone dialer or whatnot launches hte provxml which installs the xap. The XAP ships with the phone in the \windows\ folder but isn't "installed" until it's provisioned by running ##634#.

you're right thought you were asking something else

YAY! Progress!!! I figured out how to get better (full?) write access to the registry

Soo in the "Diagnosis" app they use an additional COM DLL which has a whole slew of interesting features. With this one, you can write to more of the registry. I was able to change my theme colors and some of the other fun mods

The following code removes the app deployment limit and replaces magenta with gray. I've attached the DLL that you'll need to include in your project. It would be nice if those of you who have developed apps like registry editors could update your Samsung support.

Code:

private CHybridClass_FCRProxy HybridClass_FCRProxy;
        private IHybridInterface_FCRProxy HybridInterface_FCRProxy;

        public void DoHack()
        {

            this.HybridClass_FCRProxy = null;
            this.HybridInterface_FCRProxy = null;
            this.InitializeComponent();
            ComBridge.RegisterComDll("FCRouterProxy.dll", new Guid("BE2E2E71-FC72-4507-B8AD-A2FED536AAB0"));
            this.HybridClass_FCRProxy = new CHybridClass_FCRProxy();
            this.HybridInterface_FCRProxy = (IHybridInterface_FCRProxy)this.HybridClass_FCRProxy;
            bool success;
            this.HybridInterface_FCRProxy.HKLM_RegistrySetDWORD(@"Software\Microsoft\DeviceReg\Install", "MaxUnsignedApp", 2147483647, out success);
            if (!success)
            {
                string str;
                this.HybridInterface_FCRProxy.Error_GetLastErrorMessage(out str);
                MessageBox.Show(str);
            }

            this.HybridInterface_FCRProxy.RegistrySetString(0, @"ControlPanel\Themes\AccentsDisplayName\0409", "10", "Gray", out success);
            if (!success)
            {
                string str;
                this.HybridInterface_FCRProxy.Error_GetLastErrorMessage(out str);
                MessageBox.Show(str);
            }

            this.HybridInterface_FCRProxy.HKLM_RegistrySetDWORD(@"ControlPanel\Themes\0\Accents", "10", (uint)0xFF1B1B1B, out success);
            if (!success)
            {
                string str;
                this.HybridInterface_FCRProxy.Error_GetLastErrorMessage(out str);
                MessageBox.Show(str);
            }
            this.HybridInterface_FCRProxy.HKLM_RegistrySetDWORD(@"ControlPanel\Themes\1\Accents", "10", (uint)0xFF1B1B1B, out success);
            if (!success)
            {
                string str;
                this.HybridInterface_FCRProxy.Error_GetLastErrorMessage(out str);

Soo in the "Diagnosis" app they use an additional COM DLL which has a whole slew of interesting features. With this one, you can write to more of the registry.

I'm not able to add the COM DLL to my C# project. Am I missing something here? I'd like to test it out.

There's a few things you gotta do to get native code working. Check out this thread (and my sample solution) for more info.

DUDE Thanks SO much for taking the initiative on this.. We're getting somewhere good on this! Let's get the Samsung community in the same lime light as HTC!

There's a few things you gotta do to get native code working. Check out this thread (and my sample solution) for more info.

It's a Native COM DLL, not a .net dll.

Do you think it'd be possible to write a managed wrapper DLL for the native calls? I think that'd make the whole process a lot less messy.

I took a look at your native calls project, and I must admit, I feel a bit silly. I'm not sure what to define ComBridge as. I can't compile without it.

YAY! Progress!!! I figured out how to get better (full?) write access to the registry

Soo in the "Diagnosis" app they use an additional COM DLL which has a whole slew of interesting features. With this one, you can write to more of the registry. I was able to change my theme colors and some of the other fun mods

The following code removes the app deployment limit and replaces magenta with gray. I've attached the DLL that you'll need to include in your project. It would be nice if those of you who have developed apps like registry editors could update your Samsung support.

Code:

private CHybridClass_FCRProxy HybridClass_FCRProxy;
        private IHybridInterface_FCRProxy HybridInterface_FCRProxy;

        public void DoHack()
        {

            this.HybridClass_FCRProxy = null;
            this.HybridInterface_FCRProxy = null;
            this.InitializeComponent();
            ComBridge.RegisterComDll("FCRouterProxy.dll", new Guid("BE2E2E71-FC72-4507-B8AD-A2FED536AAB0"));
            this.HybridClass_FCRProxy = new CHybridClass_FCRProxy();
            this.HybridInterface_FCRProxy = (IHybridInterface_FCRProxy)this.HybridClass_FCRProxy;
            bool success;
            this.HybridInterface_FCRProxy.HKLM_RegistrySetDWORD(@"Software\Microsoft\DeviceReg\Install", "MaxUnsignedApp", 2147483647, out success);
            if (!success)
            {
                string str;
                this.HybridInterface_FCRProxy.Error_GetLastErrorMessage(out str);
                MessageBox.Show(str);
            }

            this.HybridInterface_FCRProxy.RegistrySetString(0, @"ControlPanel\Themes\AccentsDisplayName\0409", "10", "Gray", out success);
            if (!success)

                MessageBox.Show(str);
            }

Gotcha. Thanks.

@davux: Freaking awesome. Works flawlessly on my Focus. Kudos.

MalooMF9 · Jan 15, 2011

Well, I spent a while hacking together my first ever C# program today. Though to call it mine is a bit of a stretch. What I've done is I've taken a Registry editor for the Samsung Focus (here), and modified it to use this DLL instead.

It successfully reads and writes to the hklm hive, but I have not tested it on hkcu. I've used it to keep my phone from relocking and manually editing the theme data. I haven't run into a registry key I can't read or write with it.

However, it still doesn't browse through the registry, only edits stuff you know the locations of.

Enjoy, either way. And ignore the silly splash screen I threw together in twenty seconds and forgot to remove. Source is included. xD

Edit: Found a minor bug, the default path that it starts on points to a key that doesn't exist. (Namely, the actual key is in hklm, not hkcu)

I can write to that registry key and put in whatever path I want. The problem is, whenver I try to run it with a provxml that I've deployed to the rigtones folder or to the app's install folder it does nothing. I was able to get it to launch the provxml that installs the AT&T crapware so I know it is working after it's modified, I just can't convince it to run one that's not in \windows\. I tried emailing the file and saving the attachment (took some tricking) and that didn't work either.

Did you email the file in your \windows folder, or another one you created yourself?

ad what do you mean by "I just can't convince it to run one that's not in \windows\"?? it cannot run a program not in the \windows folder or cannot install a provxml that in not in the \windows folder?

thanx

I think someone said they're working on one that will abstract all platforms. Hopefully they'll incorporate this.

Saved email attachments go to "\Application Data\Volatile\EmailAttachments\AttachmentsXXXXXXXXXXX" where XXXXXXXXXXX is some random number it assigns. I don't know of a way to get the file from that folder to \windows.

It won't install a provxml that's not in the windows folder. I tried putting the same provxml that it normally uses in other folders and it won't run it.

Here is my registry app with cross device writing (at least HTC and Samsung, LG may work).
XAP: http://bit.ly/eEZ0Uf

It includes a lib that abstract registry API for each device.

How do you detect the type of the device? or is it just a "try ... catch" and whatever works if the one to use?

Samsung Registry and File System Access?
