(SOLVED)SD Uploader can't flash new code

cepics

Hi all,
I was trying a code on a stack running SD Updater
I forgot to put inside the bin file this part of code

#include "M5StackUpdater.h"

and


  if (digitalRead(BUTTON_A_PIN) == 0) {
    Serial.println("Will Load menu binary");
    updateFromFS(SD);
    ESP.restart();
  }

now I really don't know how to exit the app...
M5Burner don't do the job!! and say: timeout waiting for packet header

please

I solved like that:

with M5Burner flash a different firmware in the stack like uiflow
and than flash again lovian firmware..

tnks
