Heres the story. I have a 4th generation ipod (some people confuse this with the earlier models that multiple buttons above the wheel). My ipod model is pictured here so there is no confusion. http://regmedia.co.uk/2004/07/19/ipod_4.jpg My problem is that i plugged it into my computer and Itunes opened up automatically as usualy. Then it asked me if i wanted to update my ipod, so naturally i hit Yes. Everything worked fine until something came up on the screen telling me to plug my ipod into an AC plug to finished the update. uhh. This is strange to me because i had a frst-gen nano and never had to do that. Anyway, i dont have the original AC adapter that came with it but i have a Griffin AC power supply (pictured here) Ihttp://img.thefind.com/images/UwDrntsiNY1hGsMhSRaG1JzU5JKi_LzM5GKGjJKSAit9_fLycr38tLTM5NSU1IL8Er3k_Fz9gszkktKi1GL9YG99Xxd9U3MjczOz-OLs-NwUvayCdAYA?m=1&g=2. Thinking i was in the clear, i plugged the ipod in with my Griffin AC adapter and..............nothing happened. I tried restarting the ipod holding the center and menu buttons at the same time, it restarts but the same screen comes up waiting for me to plug it into the wall. I tried letting the ipod run out of battery power and try again but that held the same result. That is a 20GB ipod and i would rather not just stick with my 1GB nano. The ipod doest even 'turn on' to the apple menu or even the backlight never comes on. I is not even recognized in my computer anymore so i cannot wipe it to try and fix it. Any help is appreciated and i would rather not buy a firewire cable which i heard works when the AC cable is supposed to do the job. Thanks in advance to any help.....btw i finally got rid of the 'newcomer in training' thing and am now a member..WOOHOO haha.
