MeshCore 1.17.1 is currently installed, but I can't connect via Bluetooth anymore. That's why I wanted to start fresh, erase or flash a working version.

I've tried some button combinations but none of them get the v3 go into download mode. But I'm open to try more. Got any button combinations I don't know about?

I'm trying to flash from CachyOS in Ungoogled Chromium (installed from Flatpack, maybe that's an issue too?)

Iam on cachy for daily use, can't get it to work either, for the moment I switch to chrome on wind .PC ,just for meshcore.

Got 2 heltec v4 in use with graphene OS phone ,try deleting Bluetooth connection on phone or PC and reinstall Bluetooth connection.

Otherwise I had succes with Parrot OS home edition,for uploading firmware by serial port to heltec v4
