iPod touch iPod Touch unusable

[baharini]

Hi, I'm hoping someone can help me.

My iPod Touch 4g was running 4.2.1, jailbroken with greenpois0n rc5b2.
It somehow got stuck at the Apple boot logo and hangs forever.
It does not detect in iTunes, and will only be detected in DFU mode. When I try to put it in Recovery mode, it displays the connect to iTunes logo for 1 second, then reboots and shows the apple logo hang.
Whey you try to restore in iTunes in DFU mode, it displays the Recovery logo for 1 second then shows apple logo.
I have tried running TSS server and entering recovery in Tinyumbrella, but that didn't work.
Could someone help me fix it?

I remember there is an ancient thread what talked about how to rescue your dead iPod Touch.

But I can't find it now. If I were you, I will try to turn off iPod, connect with iTunes and then hold on both buttons till iTunes told me there is an unknown device need to be restored. Maybe you are specific but I hope it will be useful.
