Nexus 7 (2012) won't charge or start after a series of problems today

A year or so ago, I bought an old Nexus 7 that was very slightly used (I took it off my girlfriend's hands). Everything worked fine, but I barely ever used it.

Two days ago I broke it back out. I charged the battery to full but never ran anything. The next day, I opened it up again and noticed that there was an update - 5.1.1. Not researching beforehand, I went ahead and tapped the notification, and then the problems started flooding in.

First, the tablet became locked in the loading animation after the Google logo. I let it do this overnight just in case, and it was still stuck in the morning. So I held the power button and volume button until it turned off and tried to reboot it.

At this point, it booted to a 'No command' screen. I did a factory reset from here, and rebooted. Now the tablet became stuck in a reboot loop of the Google logo.

After some research, I flashed it back to version 4.4. Everything worked fine with the fastboot and everything was working great. I ran a few updates from the tablet and got to version 4.4.4. Again, it loaded fine.

I tapped the envelope icon in the top-left corner to view my e-mails. As I was reading the first one, the screen froze. I let it sit for a few minutes and it was still frozen. So again, I powered off by using the power and volume button. My battery was around 30% at this point.

Now the tablet shows absolutely no signs of life. I have tried holding the buttons with all of the combinations that are online, I have tried doing combinations of buttons while plugging/unplugging the charger. I have tried using a regular micro-usb charger as well as a 2A charger. I have tried reseating the battery. NOTHING has worked. The tablet shows NO signs of life - no flashing, blanks, anything at all.

What can I possibly do?

The battery is probably pretty dead - lithiums should NEVER be allowed to go below 40%, and leaving it for a year probably dropped it a lot lower than that and left it there for months.

IOW, already below the minimum point you should let it drop.

Now the tablet shows absolutely no signs of life.

Plug it in and leave it alone for at least 24 hours. If nothing happens, you need a new battery just to troubleshoot it.
