Friends! I am looking for a person who potentially has contacts in Sony

Under my articles on Habré, whoever didn’t write – readers had the rarest prototypes of a Siemens phone, and development engineering samples of Bada Samsung smartphones, and even a BlackBerry Z10 prototype! However, just recently I was offered a very rare and cool engineering prototype by Sony Ericsson. And her name is Julia (Jolie)! The bottom line is this: until 2011, Sony actively collaborated with Microsoft on the release of devices on a mobile OS from small soft ones. WP7 was just getting ready for release and the guys started sending prototypes to potential developers to motivate them to port their applications to the new platform. Thus, Julia ended up in one of the offices in Russia. However, the fate of this device was a little sad: someone got the device for themselves, decided to flash it for some reason with some kind of left firmware (I think, from lumia or HTC Radar) and got a brick. And this is despite the fact that the device already had an unlocked bootloader. Where do I need your help? Perhaps one of the Khabrovites worked at a Sony branch in the Russian Federation or simply has contacts with Sony Mobile or Microsoft. Can you try to help find the firmware for this device somewhere in the backups? Or maybe someone has such a device and together we will try to dump the firmware? I believe in the power of habr and readers 💪
