po ovome i nije sve isto, sa xda:
Q4-BUT, THE HARDWARE IS THE SAME, WHY WON'T WP7 JUST BOOT NOW?
A-Because the hardware isn't actually the same. Yes the HD7 has more or less the same specs, but the hardware itself is completely different. Different processor, different type of RAM, different storage. Its not as simple as just hacking the RUU to work with the HD2, proper drivers have to be written first. Its just like Android at this point.
