I’ve been unable to get into the mangoh via fastboot to flash a new yocto image. I’ve followed serveral tutorials online but the device still is not showing up. Has anyone run into this problem / have any solutions?
What version do you have?
Release note here mentions various limitaions: http://source.sierrawireless.com/resources/legato/wp85crn/ …
I’m having the same problem. I’m using the version that shipped with the board.

Here are my steps:
I created udev rules 51-android.rules and rebooted
SUBSYSTEM==“usb”, ATTRS{idVendor}==“1199”, MODE=“0666”
SUBSYSTEM==“usb”, ATTRS{idVendor}==“18d1”, MODE=“0666”
Put MangOH in boot mode:

john@john-Latitude-D620:~/android-studio/sdk/platform-tools$ sudo ./fastboot device

Also adb works with other devices such as my phone and a tablet but not with this device. How do I enable it on the MangOH board?
Fastboot should work with latest firmware (release 11 onwards):

Can you retry that? We just did and it seemed to work.

I tried the 16.04 version 11 and still have the same results. I was able to get a phone into fastboot mode and recognize it using my host PC. Here are the results
