Yet again, my iPod Touch had the white screen of death. However, it was rather annoying to solve, since it now has a broken home button, so I could not simply do a hard reset to fix it.
To fix it, I needed the SHSH blobs for its current version of iOS, which is 5.1.1
First, I stitched these blobs into the appropriate 5.1.1 IPSW using redsn0w.
Next, again with redsn0w, I checked the status of the iPod. It appeared to be in normal mode, i.e. on.
*Without* going into pwnedDFU mode through redsn0w, I attempted to restore it through iTunes with my stitched IPSW.
iTunes then obliged to put the iPod into restore mode, nicely rebooting it in the process.
Once iTunes gave the error that I received last time, the iPod simply rebooted itself, back to a fully functional state.
Hope this information helps anyone in the same situation as me.
