Troubleshooting PW2 goes silent after flash erase

[cursive]

I have an old PW2 that couldn't boot up. I soldered a serial adapter and used PuTTY to access the terminal. At first, I could access the terminal and send commands, but could not boot into diagnostics, it got stuck in a loop, and was sending out error code -110. I then mess around, and I got stupid, so I pressed erase MMC0. Now, the terminal is silent, and there is absolutely no messages sent from the kindle to the terminal. When unplugging and plugging the micro usb port, there is a connect chime on my laptop.

Is there a way to recover from this? After looking around, it seems that most people are still able to access the terminal after erasing, but in my case, it goes silent completely. When holding down the power button, it still does the 5 flashes and reboots, as i can hear a disconnect then connect chime on the laptop.
