Good morning, I have this module purchased in 2016 which attached photo to link

I have it connected to an APM with a Ublox 6M GPS and it was having a random signal in my ATT (the yellow light was sometimes fixed and sometimes it was blinking).
What I did according to this video ( ) is to update the signature but now the module does not work. It does not even turn on the indicator LED.

It may be that the wrong firmware is loaded.
You can send me the firmware that corresponds to this module.

Thank you
