I've bricked my psp. It will not coldboot, so I can't get to the XMB. When I try to coldboot, I get a forever lasting black screen until I turn it off manually. I can use recovery mode. I got it this way by having messed up fonts, thinking I could downgrade using the HEN 3.03 method at http://www.noobz.eu/joomla/index.php?option=com_content&task=view&id=38&Itemid=88888898 I used an ISO for my Grand Theft Auto, and my brick happened after the first step, which is getting HEN running. I have no idea what to do. Please help me! I spent a long time saving up for my psp!!
