I guess, the original question was how to re flash LoraWan bootloader to Meshtastic?
I have the same question. Has any one done it?
It seems the Lorawan bootloader is locked.
It doesn’t present COM port when in DFU mode.
And also droping a converted hex to uf2 S140 7.3.0 bootloader to MSB doesn’t get accepted.
My goal is to flash S140 6.1.1 for SoftRF.
