Download this
kangerade.scripts.apk then install the .apk, when its done go to your app drawer and run it, Kangerade Scripts, go to fonts, select the font you want to try and tap it. After a few seconds it will tell you its install, then you just reboot and your done! As for boot animations, there is another thread in this section entitled goodies. Just DL the boot that you want, place it on root as update.zip and instll through recovery. I switched over to the classic Droid boot and droid font earlier today with no problems.
Which Terminal Emulator are you using? There are 2 on the market place. Terminal Emulator always force closed on me so I tried Android Terminal Emulator and it works like a charm.
I second this, had FC with terminal emulator but Android Terminal Emulator worked great. Though, with canvs Kangerade Scripts front end, you dont need terminal emu!
