Unsuccessfull Flash Process (1.2.1) (mac/osx)

Hi All, I tried to flash my AudioMoth from 1.2.0 to 1.2.1 and lamentably I didn't finish successfully. I appreciate in advance the solidarity of the Audiomoth's Community. To summarize: 1) I downloaded the last firmware to flash from: https://github.com/OpenAcousticDevices/AudioMoth-Configuration-App/releases

2) I downloaded the flash tool for Mac Users from:

https://www.openacousticdevices.info/flashing

3) I executed the step by step from: https://www.openacousticdevices.info/flashing

4) During the step 7). Step 7: Flash AudioMoth device, the bash print the error "ERROR: Timed out waiting for send confirmation from AudioMoth", that seems that the Audiomoth is not reachable: I reviewed that the AudioMoth is in "custom" switch on, without batteries and without micro SD Card, so the pre-requirements are ok.

The troubleshooting process that I executed was:

1. Repeat the process . The results was the same error.

2. Execute the process as a root. The results was the same error.

3. Change the privilegies in flash executable and also in the device: chmod 777 dev/tty.usbmodem14201 chmod 777 flash A new error appeared ERROR: Did not receive response from AudioMoth after sending chunk Below is the terminal print screen: sh-3.2# cd Desktop/flash/

sh-3.2# ls
