Description

Hi folks.

I have a T-Echo and installed 2.5.14
I added a 6000mAh battery and was looking to see how long it would last, but in the morning I realized that the T-Echo already stopped working in the night. Bluetooth wouldn't connect and the LEDs would flash blue-red-red.

Plugging it in on my PC via USB would just give reconnects every ~2 seconds.
I found a help article here and started following it (Xinyuan-LilyGO/T-Echo#18 (comment))
Burning the bootloader worked and uploading different firmwares works, but the device is still stuck in the reboot loop.
I yet have to successfully delete the filesystem.
Serial Monitor ends an error, assert block lfs, so I suspect a corrupted filesystem might be the ultimate reason.

I worked on this kinda in between other things today, so I am sorry this report is not as detailed as it could be and that I didn't grab the original logs.
I hope this still might come in useful to somebody. If I manage to fix the device, I will document it here.

Relevant log output

Try the factory erase uf2 process

Formatting the filesystem fixed my T-Echo 🎉
I don't know the root cause why it broke, so let's see if it happens again...

I installed meshtastic CLI in Windows Subsystem for Linux (WSL) , but that didn't work on the first try, so I used Arduino IDE instead.

Could we adapt the documentation regarding that any serial terminal works, not just "meshtastic --proto"?
