With Symfony 2.7, you could customize a form's name in your EntityType class with the method getName()
This is now deprecated. Is there another way to do that with Symfony 3.0 ?
I have custom prototype entry_rows for collections that I would need to use in different forms.
Since the name of the rows is based on the form's name, I would need to change the later in order to use them with a different form.

You should implements the getBlockPrefix method instead of getName as described in the migration guide here.
As example:
/**
* Returns the prefix of the template block name for this type.
*
* The block prefix defaults to the underscored short class name with
* the "Type" suffix removed (e.g. "UserProfileType" => "user_profile").
*
* @return string The prefix of the template block name
*/
public function getBlockPrefix()
{
return "form_name";
}
Hope this help

Depending on how your form is built, there is different ways to set the name of your form.
If you are creating the form through $this->createForm(CustomType::class):
$formFactory = $this->get('form.factory');
$form = $formFactory->createNamed('custom_form_name', CustomType::class);
If you are building the form from the controller directly through $this->createFormBuilder():
$formFactory = $this->get('form.factory');
$form = $formFactory->createNamedBuilder('custom_form_name', CustomType::class);
Look at the FormFactory and FormBuilder APIs for more information.
