Ok guys, problem solved

Help yourself and God will help you :)

Problem was programming speed (I think it's problem of PCB design) because I hasn't similar problem in another construction with same chip.
I download but when a try to programming bootloader verification was failed.
But in this tool is possible disable fast programming and programming ok wrify ok and PB bootloader cdc connection working.
Firmware update without any problem.

I hope this helps someone with similar problems.

4. In Certificates snap-in, select Computer Account, and then click Next.
5. On the Select Computer dialog box, select Local computer: (the computer this console is running on), and then click Finish.
