I need Solve the problem of decoding the network after the end of 10 attempts ;
Are i need to flash trim?

What trim? Just to be clear - you've made trim area backup before entering 10 unlock codes, then you've blocked unlock attempt counter and now you want to write back your own trim area?

yes
how can i do ?

Then write it back the same way you've created backup. I don't know what tool do you use to service your phone so i can't help you more.
