XDA Developer, tytung has done a very well done job on bringing good ROM and GPS Libraries to HTC HD2. I tried his Froyo, Gingerbread and Ice Cream Sandwich ROM. And now he has Android HTC HD2 ROM based on CyanogenMod 9. This is the version that he is currently developing and supporting. So whoever love to use Android 4.0.3 Ice Cream Sandwich ROM on HTC HD2 should try out this very ROM.
Personally, I did not able to try this ROM because my HTC HD2 is not with me at the moment. So I have no idea on the ROM performance and features. You need to tell me after try it out.
Note – You need to use 165MB CWM partition layout size for V1.4. And do refer to XDA website for more info on how to increase the internal storage size.
