3GS 3.1 Jailbroken, wont reboot quickpwn logo frozen HELP

[cdesigns]

I have been using my 3GS iphone jailbroken without a problem for 2 weeks.

I just sold the phone on ebay and decided to ERASE ALL DATA AND SETTINGS directly on the phone , after it finished I saw the APPLE logo botting up and then the quickpwn logo but it stayed there.

I tried holding down HOME and SLEEP buttons until it turns off and what it does is reboots to the quickpwn logo and nothing happens.

Itunes doesn't see it, no matter what I do.

WHAT COULD BE THE PROBLEM? I need to ship this phone tomorrow please HELP

You need to put the phone into DFU mode, iTunes will then see it and you'll be able to restore:
