I followed this procedure 10 times and each time it failed. The failure presents itself after I've placed my phone in DFU mode and the software is indicating it is installing the iPod baseband software. I receive the "please wait" dialog but after a few moments RedSnow just shuts itself down without any message (error or otherwise) being displayed. I tried running in XP compatibility mode and as an administrator but it didn't work. Any suggestions on hot to get around this?

then you download redsnow 0.9.15.b3 then open it and click on extras then even more and then dfu ipsw then select ipsw and restore with that ipsw and iphone will enter dfu mode

Thank you so much, I successfully installed jailbreak on my iPhone 3G iOS 4.2.1. Restore firmware with iTunes takes about 12 minutes until it asks to activate with a SIM card. Note that I has issues with battery, so as soon as redsn0w finished I plugged the iphone to wall charger.to prevent yellow screen. It's mandatory to start firmware flashing with high battery.

Link for redsn0w is dead... I can see when I mouseover it was linked to v0.9.6rc8... should I get that version? or something else/newer? Most newer versions seem to be Beta.

Worked with v0.9.6rc8... it froze at uploading ramdisk (step 12)... after 10min it shut down. Closed everything, started redsn0w again, as soon as started I clicked ctrl+alt+del and went into task manager, then the processes tab. Found redsn0w in the list, right-click, went to Set Affinity, in there it listed processors... multicore system... so I unchecked everything except CPU 01, then ran the steps from there and worked perfectly fine.
