Microsoft Makes It Difficult For WP7 Custom ROMs

We’ve posted about an HTC HD2 allegedly running Windows Phone 7 courtesy of the underground development community and we also showed you a five-minute video of that certain Leo running Windows Phone 7 side-by-side with an HTC 7 Surround.

Well it looks like all the hacking and custom ROM baking process will be a bit slowed down (to say it will be stopped would be a bold statement) as it turns out that Microsoft has built a Genuine Software verification algorithm into its new mobile platform, going by the name of PVK (stands for private keys). The operating system polls the motherboard inside the phone for these private keys when doing certain operations and if those keys are nowhere to be found or corrupted, some fundamental features like Xbox Live, Zune, Marketplace and Windows Live will stop functioning. Now if this happens on a Windows Phone 7 legacy device, the motherboard has to be replaced but if this happens on a custom ROM, there’s not much to do (but the game of cat and mouse will continue as we’re sure the community will have just another obstacle to try and pass, who knows, by emulation? Just sayin’…).

While you might remember our post about the existence of an alleged ban for Xbox Live, tightening up the security on Windows Phone 7 will not only prevent (or at least try to) custom ROMs but will add another watch tower to fighting piracy when it comes to Zune, Marketplace and Windows Live.
