Garmin Dezl Cam 785lmt-s Boot Loop with spinning icon above garmin logo, pc wont see it until i attempt to enter fastboot mode (power and Vol-) buttons held down, wont actually enter fastboot mode, can enter recovery mode and see its android recovery menu,

Garmin/Leo/optimus,
6.0.1/mmb29k/jenkins12211947
user/dev-keys

Everything i try from this menu fails like, mount cache, cant open/recovery/log etc

is the mmc cooked and i should just bin it? garmin express doesnt see it, have google,android usb drivers etc and android platform tools.

Any help would be appreciated! Cheers

What were you/device doing before the boot loop stated or did you buy it like this ?
