Please help me with my problems!!

1. awhile ago I was able to do change my theme with the xmb custom firmware plugin, but I don't remember how
I did it, now after hours of changing different themes I cannot flash a dam single xmb theme, it comes up blank, then the psp shuts off I had to recover my psp like 5 times because of my font changes when I go back(I don't want the default to look different) to my regular menu.

2. I can't go into configuration in recovery mode

3. The icons Portable TV and Playstation Spot icons keep coming up and I need to go into configuration
mode to get rid of them.

I don't know what happened, but you must have changed some sort of setting or something. I would recommend reflashing your firmware... not to sure what you were talking about with the font portion, so i dont know if this next part answers what your asking about...

Known Issues

1). Custom fonts might not displaying some of the time (Original fonts appear instead of custom). This only happens when you do not have all the files in ms0:/TM/font/*here* you need all ltn0.pgf to ltn6.pgf.

2). The font changes to default in game.

3). Sometimes it doesn't change your font to your origanal font even if you have disabled the plugin in Recovery Mode.
