All you need is to download the iOS 6 IPSW from the sticky here for your 3GS

Then put your device into DFU mode by following the instructions here

Then follow the first link and the text below to get rid of any 3194 errors.

In iTunes, shift + click restore on iTunes, then point it to the IPSW downloaded. Wait for your device to be restored to iOS 6.

Download RedSn0w, run it as administrator, then go to Extras > Select IPSW. Again, select the IPSW you downloaded for iOS 6 for your 3GS. Then go back to the starting page, and press Jailbreak. Put your iPhone into DFU on your own or follow the on-screen instructions that will guide you with the counting and actions and all. Make sure you tick "Install Cydia". Then proceed.

When it's done, put your device back into DFU mode, then go to RedSn0w > Extras > Just Boot and it'll boot your device.

You don't need a video. What you need is to read the text or Google the little things you don't understand to educate yourself, and so that if anything like this were to happen again, you wouldn't have a dead iPhone and you would at least know what to do. It's straight forward and all the links give you full details on what you need to do and what the results are.
