Stuck at redsn0w 0.9.6b5 - Waiting for reboot

[shimmy]

I put my iphone 3g to dfu mode, restored and updated it, downloaded redsn0w 0.9.6b5 and firmware 4.2.1.
Now I'm stuck on waiting for reboot. Any solutions?
Thank you

Edit: Now I'm trying to ****+restore to lastest firmware 4.2.1 but it says its
not compatible? Someone please help me

You have to use Redsn0w 0.9.6b6 to put you into DFU mode first, not a manual DFU mode.

I did that but when I go into iTunes and try to restore the custom firmware of iPhone1,2_4.2.1 it says, "The iPhone "iPhone" could not be restored because the firmware file is not compatible."

[Simon]

What is the name of the firmware you are trying to restore to? Does it have a white puzzle looking cubed icon?

[shimmy]

iPhone1,2_4.2.1+8C148_Restore
and Yes it is a white cube like a lego block.
I am following iClassified.com but still no luck

Are you sure you have a 3G and not a 3GS? Is the writing on the back where it says iPhone dark grey or bright silver?

[iYeow]

Don't use DFU mode .Put your iphone into recovery mode and restore to stock 4.2.1 again.

Thanks everyone, I found the solution.
My friend didn't know and told me it was a 3g but thanks to you x98car, it is a iphone 3gs. I thought a 3gs would be engraved on the back of the phone but I guess it is not.

Edit: I have another question. Is there an untethered jailbreak for iphone 3gs 4.2.1 available? Because I cannot find anything. If so, please give me the link. THANK YOU!
