Hi, Sorry for the late reply.
Point 1.
I've figured out that, it can't read registry values at some area(dev unlocked). Used all possible capabilities. I don't know the reason, but it is may be kernel level access issue. I've not spent a more time on it, due to busy schedule. Even your WebServer app doesn't displays the content on the web page neatly, each time i need to refresh the web page to load the content on desired Web Page, but it is another issue.
Point 2.
About the OEM libraries, which
@snickler has already tried.
We can easily write the registry values at anywhere using any oem library, but their components must be pre-registered and obviously it doesn't permit without high privileges for 3rd party.
Point 3.
One Noob Question.
There are already unlocked SD Card system files
So, If we replace them accurately, same content, same library, same and linking, same as the oem developed and can launch the homebrew .dll ??
Is there possiblity to launch homebrew .dll in an OEM Installation directory and could've the advantages of registered components?
I know all components are registered in Registry and encryption levels, fails on any mods, licence checking etc-etc.
But, if we get success to launch homebrew .dll, then it will have the same privilege of the OEM(as refers to the Registry).
I'm not interested to downgrade my device to 8.0 GDR 1 and find the security vulnerabilities.
So, *CURRENTLY* this the only way to by passed the security.
Btw Happy Diwali to all of you
