I don't know if 2.3.4 is still working.
I DO know that 1.41 is working, since people are using it as a CRC bypass.
Take a look at this thread:
If that doesn't help you out, you can always buy a private bypass at the "black market" section.
OR you could contact EliteDKTrader to buy it from him, since he is the most trustable person.
