I installed the OTAFIX bootloader onto my RAK4631 and installed the MeshCore repeater firmware. Now the repeater works fine but it appears that I cannot enter UF2 DFU mode anymore. Twice fast clicking on the switch does not result anymore in the drive being shown on my PC. Neither do I see the RAK4631 as a Bluetooth device. What is the procedure to return back to UF2 DFU mode? If this is not possible, then there should be a warning in this article because it looks like that I cannot reinstall firmware anymore if I cannot login anymore to the installed MeshCore router firmware.
