Z2 Pro Bricked? (TLDR; I'm an idiot, I know) [FIXED!!!]

Well, that was fun while it lasted.
I have been having a hard time getting my computer to do adb fastboot and unlock the phone. When I finally did, I got TWRP installed and rebooted. YAY it worked! My phone booted and things were fine!
I had a couple more things I wanted to do, so I told adb to fastboot again... and now it's dead.
With the phone plugged into my Windows 10 laptop, if I hold down the power and vol up buttons for a VERY long time, the PC recognizes that something is attached, Device Manager quickly flashes some "MTK USB" entry, and then it's gone and my PC doesn't recognize anything.
Unplugged, or plugged in, if I hold the power button, or any combination of buttons, nothing happens. The screen doesn't light up at all (even to stay black).
Is my phone dead?
If I take it apart and remove the battery, would that reset some sort of PRAM or whatever that would let it boot again, or am I just out of luck?

Fixed it!
Using the following info found here

Here's an optional solution to start the flashing process on your UMIDIGI Z2 Pro if the standard method doesn't work.
It's especially useful if your phone is bricked or is stuck in bootloop
1. Connect your UMIDIGI Z2 Pro to USB.
2. Start the flashing process with the Download button in the flasher app.
3. Press and keep pressed the power button of your phone until the flashing process starts (red bar appears at the bottom of the app window), then release it. In this process you have to keep the power button pressed for about 10 seconds.
4. Wait until the flashing process finishes.
But, #3 was a little different. I had to hold the Vol UP and Power buttons and the SP tool did its thing!
I haven't rebooted again, yet, but I'm not worried anymore.
