Hello!
I have just installed rockbox on my I-Pod 5.5 Gen 80 GB unit.
Everything went well and even got it to speek for a few minutes until I went to recording mode and since then, the machine will not power down.
Of course, windows doesn't rrecognize the unit any more so I can't uninstall rockbox!
Is there a reset on this machine?
If not, maybe when the battery goes dead, I'll be able to reboot normally?
