I have an iPhone 3Gs that I wanted to update from 4.1 to 5.0.1 I downloaded a ipsw from clarified.com and created a custom ipsw using redsn0w. after put the iPhone into Pwned DFU with redsn0w. I opened iTunes and installed the custom 5.0.1 ipws successfully after I jailbroken it and installed Cydia using redsn0w and boot the iPhone by Just Boot Tether. the phone started and I started to install it by setting Languages, country and so on after a min I was asked to use a Wifi to completely install it or plug it into a computer and use iTunes to set it but unfortunately I had no internet.
I went on a shop to buy credits that I could use on my Stick modem and when I was back I found that the power was cut. I have left the iPhone plugged on my Mac computer, my battery does not hold even a min it automatically shuts down. when the power was back the phone got into schlock and when I came back I saw that it was stuck on a White Scree just after " Waiting for reboot" and "Rebooting" in Redsn0w.
I tried to rerestore using iTunes but unfortunately I got an error saying "error 1600" when I came back to Redsn0w all I did was to select the ipws manually and then jailbreak again and then " I was stuck on a Pineapple screen" I pressed home and power button and the phone restarted again stuck on a white screen.
Now when I plug the iPhone on a computer it shows that it is in DFU mode I don't know what to do either with redsn0w or iTunes to get my iPhone to work.
Hope I tried to explain this as good as I can coz my english is not so good.
please help me because right now I do not have an option that I can follow .
