I had already re-downloaded once. All hashes are correct on HDD and on phone SD card. I re-copied the file exactly over to the SD card. There are no roots in place, at all. I cache wiped, fully booted in, restarted, cache wiped, rebooted to recovery, and started the install this time. SD card had only that zip on it for updates. Here we go again, hoping for the best... Edit: For what it's worth I have a progress bar this time and didn't last time. Dunno what that means.
