Lilygo T Echo can't update firmware

Received a couple of these and was able to update the firmware, and had successful transmitting through Meshtastic, however ATAK isn’t reading the devices at all. I realized I had installed a beta release of the firmware and thought, if I install an alpha, maybe the issues will resolve with the ATAK plugin.

Well, now I can’t read the node on any of my androids via USB data cable, and my son somehow uninstalled the hard drive on my laptop (yeah, rough week) so I’m not sure where I can go from here. They’re still available via Bluetooth, and I installed the firmware via cable before just fine, but as I put, now it’s not reading by cable.

I’m very novice at all this so any ideas or help is appreciated! Thank you all in advance for any support!
