File Upload Redirect with Error Not Display

I'm not sure what is the cause of my file upload. It's failing and redirecting back, but not with error.

---

Controller

public function updateLogo()
{

    $inputs = Input::all();
    $logo_path = Input::only('logo_path');
    $cpe_mac = $inputs['cpe_mac'];
    $rule =  ['logo_path' => 'mimes:jpeg,bmp,png'];

    $validator = Validator::make($logo_path, $rule );

    if ( $validator->fails()) {
        return Redirect::to($cpe_mac.'/view-profile/')->withErrors($validator)->withInput();
    } else {

    ..... 

    }

View

{!! Form::open(array('url' => '/'.$cpe_mac.'/view-profile/logo/update', 'class' => 'form-horizontal', 'role' =>'form','id' => 'editLogo','file'=>true)) !!}

  <input name="logo_path" type="file" required> <br><br>

   <button class="btn btn-success btn-sm mr5" type="file"><i class="fa fa-user"></i> Update Logo</button>

{!! Form::hidden('cpe_mac', $cpe_mac)!!}
{{ csrf_field() }}
{!! Form::close();!!}

Did I forget something ?
