Hello! I'd like to say first that rockbox is awesome, no comparison to the original firmware. I had a strange problem, though.
Here's the thing:
1) I first installed rockbox following the instructions, and everything went OK.
2) After I installed some themes, sometimes the rockbox crashed while listening to normal music.
3) So, I tried to install ipodlinux just to see how it was. It didn't accepted my ipod model (maybe because it had the rockbox firmware).
4) I restored the ipod firmware using the ipod patcher, and it worked well. However, ipodlinux still didn't work. Oh well, time to go back to rockbox.
5) I did the same procedures to install it again. Ipodpatcher scanning, reading and writing the rockbox firmware went OK. However, it only showed the dreadful "Use iTunes to Restore" message in many languages.
6) iTunes could restore everything normally, and the iPod firmware works. However, I can't install rockbox anymore. I tried older daily builds and even tried from other computer, but the problem persists.
That's the thing... the way it is, I don't think it's a hardware problem because it can be restored by iTunes and runs normally, and its not a RTFM either, because I could install earlier doing the exact same things...
Any ideas?
