BG95-M1 wrong firmware burn

Hi All,
I have accidentally burned firmware of BG95-M3 on a M1 device.
Now the device is not responding , what should I do to get it working again?
I don’t see any com port available and all the lights on the EVB are off (except the power).


if so ,the patition table of file system has been changed ,

nv value has been changed , we can send you one factory initial version to you,

but you need to send email to , for some reason , i can not share it here .
