CyanogenMod 7 should be the best Android ROM for HTC HD2 (MIUI too). It is faster than HTC Sense builds. Besides, it is smaller in size too so you can have more internal storage disk space. HyperDroid v3 is based on CyanogenMod 7.1.0 RC0 (Android 2.3.5 Gingerbread) and using seader_R5 Kernel. As usual, it has strange LCD density. It increased to 192 from 167 DPI on v3 which is better but might still be small for certain people like me. Personally, the smallest DPI that I can accept on HTC HD2 is 220…
Note – make sure that you change ro.sf.lcd_density=192 to 240 at build.prop (system folder) before you install the ROM if you want normal screen density.
