A guy claims to have a working bypass by using a modified l2.net client W/ custom packet decryption/ encryption (http://lameguardbypass.wordpress.com/)
I have the been able to download the Custom dll files (http://www.mediafire.com/?tskm1eati8qrhbu) but the links he gives for the custom l2.net client are those stupid survey download sites......which i'm not wasting my time on.
These are the links hes gives for the custom l2.net client
Mirror 1 - goo.gl/Uzcwi
Mirror 2 - goo.gl/h30Hu
if you manage to get it downloaded please post a mirror on good site like mediafire or megashare. Please
THanks
