T1000E Gone into Brick Mode

My T1000E has been running Meshtastic fine for the past few weeks. I did upgrade it to 2.5.4 Stabile a few days ago without a hitch. However, today, I noticed on my phone it was no longer connected. The green LED is slow flashing so it’s not dead. I first tried powering it off, but I found the button doesn’t respond. So, I tried hooking it up to USB and it appears the USB connection just flaps. I’m leaving it disconnected from USB in the hopes that once the battery drains, it will reset itself.

Does anyone have any suggestions? Thanks!
