      The screen with the pineapple is normal but it shouldn't stay like that. I haven't seen the lines or heard the sounds before. It may be a hardware issue. Can you restore and rejailbreak to see if that solves the issue?

      It's not crashing. It's tethered, isn't it? Which means everytime you boot it, you have to run redsn0w again.

      En español para explicarme mejor... Anoche hice una restauracion con la mas nueva version, despues instale el cydia el cual lo tube que reparar con el redsnow seleccionando "Just boot tethered right now" ya cundo el cydia inicio normalmente me pidio que lo actualizara que habia unos paquetes que se tenia que instalar, los instale y el ipod se reinicio automaticamente lo que es comun cuando cydia se actualiza, pero al momento de tratar de entrar a cydia ya no funcionaba lo tube que volver a reparar con el redsnow seleccionando "just boot tethered right now" luego ya reparado cydia busque el winterboard y lo instale, el ipod se reinicio solo por que asi lo hace cuando se insatala el winterboard despues de esto el ipod se reinicia y se queda trabado se queda solo con la pantalla negra y el logo de apple y de ahi no pasa!! incluso trate de arreglarlo con el redsnow otra vez seleccionando "just boot tethered" pero no funciono tube que hacerle una restauracion al ipod.!!! No se que esta haciendo mal Max. Gracias por tu ayuda.

      Everytime the iPod has to reboot, you have to use "Just boot tethered right now". The Dev Team is still waiting on a way to avoid this. Once you have everything installed and working, then don't turn off your iPod and don't reboot or you will have to do it again. I got my son an iPod Touch for Christmas and haven't had to reboot it since. But I explained to him that if he ever turns it off, I will need to connect it to the computer to turn it on again just like you are doing.
