Hi, I thought that when I prised the battery out, I'd knocked 2 chips off the logic board, chances are this is what's happened to you too... They need to change this tutorial to use the plastic tab to remove the battery as I've seen several people with this issue. The only way to fix this is to get 2 jumpers soldered onto the logic board. For now, I used tinyumbrella to get it out of recovery mode & I have enable to assistive touch options.
