To be able to customize the HTC HD2 by installing custom Windows Mobile 6.5 ROMs or installing MAGLDR and using it to flash Windows Phone 7 or Android ROMs, the phone needs to have HardSPL 2.08 as well as a radio supporting 576 RAM. We have already covered the HardSPL 2.08 installation process and now, we will be taking care of flashing the 22.214.171.124 radio to the device.
Basically any radio with version number in the format of 2.**.50.** supports 576 RAM and enables you to perform the above mentioned customizations on the HTC HD2. We are using 126.96.36.199 merely because it is the latest in this list of supported radios, and has been found to be the most stable and compatible with both the global/European (LEO512) and the T-Mobile USA (TMOUS/LEO1024) versions of HD2.
