My son has an 8G iPod Touch 1G which I haven't jailbroken or modified before in anyway different than changing the battery six months ago. Before some days , the device wouldn't get bootup. It would display the apple logo for some seconds and then automatically turned off .
I have performed a tonne of research on different recovery methods, but I am getting the same evaluation of all those things . This is what I have tried so far:
* Standard Restore from Restore mode
* Restore from DFU mode
* Downgrading to an older firmware such as (3.0.7, 2.2.1, 1.1.4) with the help of an previously released iTunes (7.6.2)
* With the help of Ziphone to force this out of DFU mode
* Letting it sit for 48 hours
I didn't encountered this type of issue before but when I read your thread. I discussed about this issue to others and there are some suggestion here for you to do .. You can go for restoring the pre configured settings of your iPod first and then plug this with your compute system and it should work as it did in case of my ipod nano.
My computer system was unable to recognize my ipod and try restoring the iPod from the ipod settings menu.. I hope, this very method would work for you ..
Thanks and best of luck ..
