So, l was trying to install 9.5.-23USA update to my emunand when suddenly my system froze and powered down. I turned it back on and now it does not power up, other than the power light. Screens stay dark. I tried going in to recovery mode, and it comes up, but it doesn't matter what I press (Cancel or Update) because it just freezes. I tried starting with/without memory card, but it does nothing either way. So, how badly did it brick it? Do I have any hope of fixing it myself?
