Thanks Alex, finally with the following the last steps, we could repair all Audiomoths. Thanks again

THANKS ...ITS ALL OK..NOW..

Exactly. Is imposible to start flash mode.

Impossible. My devices don't work following all the steps.

I have tried again, but the devices with problems don't work. I have another 15 audiomoths. I had updated all of them several times. The wire works with the others. Devices that don't work started to malfuntion after the failure of the 1.4.1 updating.. (I have tried again and taken pictures to show you the result. The ones that work: and the devices with problems. Thanks again

We tried all of these options, following the steps, but they didn't work. After the problem with the update (1.4.1) that we explained in the first post, the devices didn't work at all. Apart from the updating problems, the devices don't work when we put batteries or when we conect to computer, also, the leds don't work. Could you give us a solution? Could we give you back the devices to be repaired? thanks again

Sorry for the delay. These three Audiomoths came from two different orders from LABMAKER. Two of them originally had Firmware 1.0.0 and the other one Firmware 1.1.0. (2019 and 2020). All of them were updated with firmwarer 1.3.0, in the moment of the "problem". Thanks in advance. Xose

We tried all these options, and the devices didn't work.
