Hi guys, I have tried everything I can find to try to rehabilitate my µmoth but no joy!😥 I have tried the Audio-Flash 'Show Manual Switch Instructions’ on a colleague's Win10 laptop that he uses to set up our bat group Ams (just in case its a Mac issue) - still no joy. The app shows 'No AudioMoth Found'. I am wondering if I need to get access to a SiliconLab boot loader which I don't have - otherwise the µmoth may be a write-off. Is there anyone out there that has experience of recovering corrupted(?) AudioMoths that I can send this to? Apologies if this is outside the scope of this forum but I am at a loss as to how to proceed otherwise. I live in Hampshire and can deliver locally. Many thanks,Steve

Thanks for the post Alex but the process you describe has not connected the µMoth to the AM Flash app, the app show 'No AudioMoth found'. I am powering the µMoth with a single LiPo. I have tried this before several times taking care to change the switch from 'off' to 'custom' for the 'Manual switch' procedure. I downloaded the Flash app to a new M1 MacBook pro but got the same result. The M1 recognises the AM Dev and it appears in the hardware config as you'd expect but the µMoth does not. Is there an alternative to the Manual Switch procedure that I can try please? Many thanks.Steve.
