Sorry for keeping you waiting so long.
I checked the Internet for available information about your phone and did not find very much. It seems to be completely different to the "standard" Galaxy S II, that may explain the problems:http://wiki.cyanogenmod.com/wiki/Samsun ... _S_II:_FAQ
The most important information in the table is that the HD LTE has a different radio software. This explains why it does not have the libsec-ril.so. So currently my app will not run on your phone. If you have a link to a ROM image (zip file) somewhere, or you mail me the files in /system/lib and (if existing) /system/vendor/lib, I can take a look if it may
be possible to get rSAP running. But I don't have much hope.
