Can someone help me, my info is:

Thanks to everybody

It's an at&t phone, the at&t CID is blocked by htcdev so you need to get SuperCID before being able to unlock the bootloader. Click the Everything Evita link in my signature and bookmark that thread, it's a resource thread that contains everything you'll ever need. Once you're in that thread navigate to the root section and find the 3.18 root method, this is the only method that'll work with your current firmware. Follow the instructions in that thread and then you can unlock your bootloader.

Once you have an unlocked bootloader you can install TWRP recovery which will allow you to root your stock ROM or install custom ROMs. If you need instructions on this click the How-To Guide For Beginners link in my signature, it's a thread I put together detailing some basic operations. If you have any questions feel free to ask in my Noob Friendly Q&A + General Help thread.

You need to use the correct root method that corresponds to your firmware version in order to change your CID. Trying other methods you randomly Google around for is not going to work.

Use my Index thread, look under "ROOT" and find the method that matches your firmware number (3.18).

There is not one-click method that works for firmware 3.18. Trying methods that don't match your firmware number is a waste of time.

Also, when asking for help, you need to be absolutely specific as to what you have tried, and what you haven't (including the result such as error messages, etc). If you don't give us specifics, it makes it even harder for us to help you.

Hasoon2000's all-in-one toolkit should work on 3.18. But if this is the one you tried, you haven't told us what happens when you try to use it.

Nobody here was talking about SIM unlocking.
