Thread: C75 unlocking step by step:)

For all in this post!

when you have C76 VER 11 or over use this method when not don't post nothing finde the pachv4 in other post and have fun.
This is my worked solution and I write all exactly so read it most slowly.
This not a new metod just a usable for this f***ed siemens C75.
When you make it for first time don't loose your time go and read all post in siemens x65 and x75.
Thx.
