Hello, Here's a story I hope you can help with. My PSP has Sony Firmware 3.10 on it. I bought a new PSP from walmart, which had 2.71 on it. I upgraded the new PSP to 2.80 I downgraded the new PSP to 1.50, and upgraded to Dark Alex's 3.40 OE I disassembled both PSP's, and swapped out their mother boards.(I used a heat gun, so I was able to keep both warrenty stickers intact) I put each PSP back together. After swapping the motherboard out of the new PSP, my old PSP has a problem with its sound. When there are headphones plugged into the audio port, I can hear sound out of the PSP Speakers. However, when I unplug the headphones, the PSP treats it as when headphones are normally plugged in. Some how, they got switched up! My plan is to return the New PSP back to walmart, fully functional, and keep my old PSP, just with a Homebrew capable Firmware. Any help, or solution to this problem?
