Make a MMS from catb50's or totalnewbiinstaller's makers. google em up and run the dos file. Put in the MMS into the PSP and turn it on. Depending on if you have a slim or fat PSP, slim: hold down L or X (mine worked with X) for about 10 seconds and let go. For fat: hold down X for about 10 seconds. In both these methods, your wifi and memory stick loading light should flash. Take your hands off your PSP for a little while and let the MMS do its job. After it's done, your PSP will shut itself off, take out the MMS and your pandora and plug in the AC adapter and turn on your PSP. should start normally, check your firmware, it should be either 3.80 M33 or 3.71 M33 depending on if you used either catb50 or totalnewbiinstaller.
Hope this helps, Mate
