A developer called Cotulla says he successively managed to install working versions of Windows Phone 8 and Windows RT, the ARM version of Windows 8 recently on a HTC HD2 smartphone, released in early 2010 and originally shipped with Windows Mobile 6.5.
The HTC HD2 is one of the last “big” smartphones have emerged in the Windows Mobile 6.5. Since it is largely gone out of fashion, the HTC HD2 is the toy of choice for some developers who have successively managed to make it work with Windows Phone 7 or Android. The hacker Cotulla, well known on XDA forums, went a step further, managing to launch first Windows Phone 8 on the HTC HD2 device. Not satisfied with this success, he then set out to run Windows RT version dedicated to the environments ARM of new Windows 8, still on the HTC HD2.
HTC HD2 have Qualcomm MSM 8250 processor clocked at 1GHz, with 448 MB of RAM and a 4.3 inch screen WVGA (800 x 480 pixels). In both cases, Cotulla claims to be able to get a functional system, which we can confirm trough provided screenshots and photos on his twitter account (look at below tweets). By his own admission, however, it is not a complete port: the process was essentially value demonstration (proof of concept), and both environments are still far from being able to meet the needs of daily use. Windows RT for example works here in a basic display mode, limited to 720 x 480 pixels and therefore be far from comfortable, but the specific environment such as Windows 8 in traditional desktop seem accessible.

Cotulla, which provides the results of its work through his Twitter account, gives little explanation, but seems to have succeeded in launching Windows RT (not just emulate) by creating a layer dedicated to UEFI HD2, mainly based on the work done within the DFT team of hackers.
The news did not go without causing some disbelief, so far Microsoft said it was not possible for technical reasons to migrate a Windows Phone 7 smartphone to the latest Windows Phone 8. The work of this young Russian hacker – who had already participated in porting Windows Phone 7 on HD2 – however, tend to show that if you want to do it, you can.
