Hi, I have an unmodded xbox with error 21, I have tried hotswapping without any success, does anybody have some suggestions that might help me out.
Easiest way I found was unplug the yellow cable fromt he DVD drive, it'll go to an error screen (forget which number), but that doesn't matter because by this time the HDD is unlocked. I found this easier than the whole "play a song" method.
How fast does the switch have to be from the xbox to the pc?
As fast as you can possibly do it.
By the way, this should have been posted in the "no-modchip hacks" forum.
This was the guide I followed back when I hotswapped, had no problems:http://forums.xbox-scene.com/index.php?showtopic=443489
However, it now says it's outdated, so try this one:http://forums.xbox-scene.com/index.php?showtopic=496263
