My iPhone 4 won't turn back on.
It's on iOS6, but the phone won't turn on, or even connect to the PC and turn on that way.
The top corner button doesn't work, and it hasn't for a long time.
Also, when I was trying to revert back to standard iOS6 from the jailbreak, iTunes wouldn't restore it, and redsn0w crashed when restoring it.
I'm not sure if the FW has just encountered an error or what.

If it's truly not turning on even in DFU mode, and you're sure the USB port is working, I would imagine that your phone is suffering from a hardware problem. It could be anything from a short-circuit on the main logic board, a faulty battery, a faulty flex cable, perhaps a bad dock, water damaged, etc. The easiest solution would be to attempt a warranty swapout from Apple.

Logs can be retrieved like this:
At the Finder, hit Command + Shift + G.
~/Library/Logs/iPhone Updater Logs/
On the Desktop, hit the Windows key + R.
%AppData%\Apple Computer\iTunes\iPhone Updater Logs
However, my intuition is still leaning towards hardware problem. Software restores, especially when it's a restore to a stock firmware, very very rarely "brick" the phone irretrievably without something else internally failing...

In that case, I'd advise you to post on the official Dev-Team blog, so the authors of the redsn0w tool can offer you support. If you're more inclined to IRC, try irc://irc.saurik.com/#iphone.
