I know this isn’t a meshtastic problem, But 1 of 4 of our t-beams will no longer update via USB
It happened a few weeks back with 1.1.23 and I fought with it for a while… I thought I had success once by holding the reset and pulling pin 0 low while it’s attempting to connect. But alas I still can’t seem to reprogram this one. It still seems to boot up and function fine, the screen shows incoming messages. But It’s stuck on 1.1.23
Both in Windows with ESPhome and in Linux with the included shell script - Both methods work fine on the other 3 units.
Is there a trick with these to get them back?
Is it just the USB to serial, and if so can I hotwire one of the others to the serial lines?
Will pushing new firmware from the app likely work?
