For anyone reading this thread in the future, @Anant_Rai and I solved the issue on a debugging call. The firmware updater tool was updated to v0.3.9 using `pip3 install -U hello-robot-stretch-factory` and then we were able to flash the latest firmware successfully using `REx_firmware_updater.py --install`. With the firmware flashed correctly, the robot was able to homed again successfully.
