The self files from the fixed patches are probably re-encrypted with the 'NP_klic_free' or 'NP_klic_key' that are present in /data/keys. (You could try change one byte in the /data/keys file and see if it can still decrypt those patched self.)
I will try and see what else the devs suggest.. i was pretty convinced this would work..
I have the MW3 .self files decrypted as elf but i did not do them. You can find them on NGU.. Now can make all region patches ,using them..
