Recognized developer Jaxbot, who’s previously brought us Themes for WP7, has found a new exploit which easily interop-unlocks Samsung devices for free, compared to the $99 required for the official App Hub or $9 for the homebrew ChevronWP7. However, his solution doesn’t work for Nokia and HTC devices yet, which is why he’s started a thread so other developers can join in the development process.
Basically, the exploit consists in downloading a ZIP that is automatically unzipped not into a random subfolder of \Application Data\Microsoft\Zipview\, but rather a parent directory – in this case, \provxml\. This works by creating a folder in the ZIP file that’s called ../../../../provxml, with each ../ going up one directory. The catch here is that devices from Nokia and HTC block the writing of some of that \provxml\ stuff into the registry.
Now please, keep in mind this is very much a development project, a work-in-progress, before continuing to the forum thread. Promise us you won’t post anything that is not development-related, okay?_________
