Hello there. I just flashed my PSP to M33 3.71, and I have a bit of a problem. See, afterwards, I tried to upload a theme to the PSP, but then it would freeze at the Sony Entertainment America bootup screen. So, I thought it was the theme's fault, so I removed those files and tried again. Now, it won't even go into the recovery screen, let alone the Bootup screen. What is up? Thanks for any help you can offer.
