Hi,

So I have deleted the URLs in this registry key to prevent my device from relocking every time I synchronize with zune

Code:
[HKEY_LOCAL_MACHINE\Software\Microsoft\DeviceReg]
    "PortalUrlProd"=""
    "PortalUrlInt"=""
Now I've got the NoDo update, I want to relock it again and use the official program from Microsoft to try to analyse how it works maybe we can come up with something that will enable future devices to be unlocked too. (I have a dev account)

The thing is that, I cannot write back to URLs to "PortalUrlProd" and "PortalUrlInt", the Samsung DLLs doesn't allow writing more than 30 characters string values to the registry, and as far I believe we have no provxml capabilities on Samsung.

This works
Code:
Samsung.RegistryWrite(Samsung.RegistryKey.LocalMachine, @"Software\Microsoft\DeviceReg", "PortalUrlProd", "A 30 CHARS STRINGGGGGGGGGGGGG");
This makes the app crash
Code:
Samsung.RegistryWrite(Samsung.RegistryKey.LocalMachine, @"Software\Microsoft\DeviceReg", "PortalUrlProd", "A MORE THAN 30 CHARS STRINGGGGGGGG");
If you have got any ideas about how to get the URLs back I'll be thankful.
Please notice that once locked, you can never unlock it again, even with an official dev account since the phone won't know where to grab the response from

By the way, I think this will work too...

Instead of entering the long https://... url you could type this:

http://unlock:443/

Then edit your C:\Windows\System32\Drivers\Etc\Hosts file and add this:

127.0.0.1 unlock

Notice that I use http instead of https. This way you don't need a certificate. Also ChevronWP7 only has a certificate for the original url. The url I gave doesn't really exist. But the change in the host file will forward the call to the local machine. Port 443 is actually the https port on which ChevronWP7 is listening.

So with these changes you should be able to use ChevronWP7 for locking and unlocking. But you won't be able to use your valid developer license because the phone will still not be able to reach the original servers.

A hard reset will restore the registry-settings, so if you really want to use your legit license you can hard reset of wait a few days for my registry editor.

Ciao,

I am not sure if ChevronWP7 works with NoDo, I am running the 7390 build now.
