You won't find the md5 value in the log (Samsung patched that a while ago), instead, run this on a Linux machine (or in the Android terminal):
(cat nv_data.bin; echo -n Samsung_Android_RIL) | md5sum

Samsung updated the efs in one of the 4.3 roms and above. Your 4.1 rom doesn't recognise it as the 4.1 rom cannot read a V2 efs and since you started out with a v2 efs you cannot do anything with Rom versions below 4.3.
Restore your original rom or install a custom 4.4 rom regain your imei and either pay for a code or contact your carrier. This app is useless in your case..
