I've tryed myself make the cdma rom by using some of HTC Desire GSM unofficial roms. But problem is: phone is not booting after flashing. I've tried to change build prop lines to cdma settings and use original jellybean boot.img instead, but annot fix it. And can't find the thread about it!
P.S. Possibility of using GSM JB roms we have after somebody previously make ICS & JB fix for CDMA Desire. And explanation in that thread about build prop chainges for CDMA instead of GSM. Will be wiiting. If I find or make one, so will test & continue CDMA Desire KitKat thread...
