New version of teamspeak server for android/ios client

[Yolo]

Hi, are a method for install 3.0.12 and client android/ios with cracked version (old version of 2013) can connect? i have to edit the virtual server settings?

I think you'd have to directly edit the server binary.

binary file are undecryptable... are locked... i can't... i think i will use 3.0.11.4 because alot of my friends use cracked phone version

The minimal client version is hardcoded since 3.0.12. So you will not be able to connect with older client versions.

Okay, thanks for support. i will install 3.0.11.4

Just breakpoint the UDP connection handler and walk the stack, it should come across a memcmp() call and that will give you the pointer to the hardcoded version, It most properly be build number stored as an int (how i would do it less memory that way.)

@ehthe did exactly that i see.

I didn't breakpoints anything because I have no knowledge about reverse engineering x)
I just opened IDA, went to click on find byte stream and put the version string there. Then I tried really hard to understand what all those things meant
