In SM-G800F I can delete many things without full crashing...
So I delete ccm.dat knox.dat and folders...
So only this folder + file(s) left:
Code:
/efs/prov_data/dev_root
As i can write DRK via AT cmd... I "know" what is inside dev_root.dat...
Still I can NOT decrypt...
ccm_gen_cert create folder ccm + ccm.dat file...
After reboot knox and knox.dat is created... by "something"... no idea what...
Trustlet is not encrypted...
I can also play little bit with libcrypto.so ... less crash as less secured...
But...
I have libcrypto.so deleted IMHO in Android 5 and performed AT+DEVROOTK...
Successfully... so maybe not involved in this process...
But ccm_gen_cert for sure need proper libcrypto...
Otherwise this:
Code:
