Keep your phone connected on the charger for some time. Then try to boot it again.

Thanks for the fast reply, but it's not just flickering anymore, the screen never comes on at all. I left it plugged in overnight, but it still will not do anything (no LEDs, backlight, nothing) without being plugged in. It kind of seems like there are two issues here, the screen not working, and now the battery not charging or working.

Might be a silly question... But did you pull out the plastic tab covering the battery terminals?

You have to pop the back cover and remove the plastic barrier on the battery. Seems like that would cause the screen to not work and the battery to not charge if it's still in place.

Yes I did. It was holding a charge, running off the battery, and indicating a 90% battery during the 1 or 2 boot cycles where the screen was actually working. Any other ideas?

Bad battery or the orientation of the battery is wrong maybe. Do you have a multimeter to check the battery and the pins on the phone while plugged in?

If not you could get a new battery to eliminate or more likely confirm the battery as the issue

4.1 volts on the battery disconnected. I plugged in the phone without the battery and see a pulsing 4.2 volts on the pins. Now, for whatever reason, it's powering up again (I'm seeing the LED sequence) with the battery only, not plugged in. I hear the auto focus click on startup too, but still just a black backlit screen, no image.
