Instructions not working on bricked device

I have had some trouble with this process on my HD8. I have it open with battery disconnected. I have TP28 shorted to the ground pad next to it. I have made sure the board is not shorted anywhere else with metal shavings or anything. I previously had the serial error, but have since uninstalled ModemManager and made sure that Python3-serial is installed.

I run the ./bootrom.sh from the amonet folder, and I see the expected prompt:

:-$ ./bootrom.sh
[*timestamp*] Waiting for bootrom

I hold the short, and then plug the USB, but nothing happens. I know that it is connected, because I get the following data from the log outputs:

When TP28 is shorted, I get:

:-$ lsusb
...
Bus 003 Device 021: ID 0e8d:0003 MediaTek Inc. MT6227 phone
...

When I plug in without shorting TP28, I get:

:-$ lsusb
...
Bus 003 Device 022: ID 0e8d:2000 MediaTek Inc. MT65xx Preloader
...

dmesg gives me:
