My H20 has dosen't worked today,it can't be powerred off,it just restarted over and over again.I want to give it a "manual factory reset" follow this site,I have done the step1 to the step4.and I see the black screen with "Critical error message" and a "√"check mark icon in the screen.But I can't tap it,however I tap, it gives no respons.So what have I to do to make it works?
