Bad business, no button is difficult, but hey, you just have to be patient and leave it at that, you may leave this alone or Expiral but the battery is finished and restart to re conecdtarlo.
Ojo, given your problems, be careful where you do the restoration, trying by all means, use a computer that is not used to make the jail, lest yours have changed the file etc Sintema and continue with a new problem.
