After buying my PSP off of Amazon, I found out it had a homebrew firmware called Dark Alex. My firmware is 3.03 right now and I'm trying to update it. I seem to have the same problem as this guy. Can somebody take me through a step by step process of installing the Dark-Alex firmware so my PSP doesn't become a brick while I'm trying to install it? Also I'm a complete noob at computers so can somebody tell me what a .rar file is?
