change mac address wifi topic

Hi , I'm using ROM v3.1 on this thread : http://forum.xda-developers.com/show...46874&page=146
And I don't know how to change Mac address of the WiFi connection.

There are a lot of app that did this but they ate not working on my ROM.

My phone is a ZTE V987.

Thanks a lot for your help.

PS : I want to change the Mac address because it seems that my Mac address is blacklisted on the hotstop that I want to use.

Thanks for your help.
