My Reach RTK Edison accidentally being updated by m_iot_dev_kit installer

I was attached one of my Reach RTK GPS and install this installer “” at the same time.
the installer also updated my Edison board. Now, I’m unable to reach my board thru reach.local:5000 nor reach_rover.local. Could anybody let me know how to restore to previous version.

You will now need to reflash your board back to our image.

Follow the docs guide

Yup, it works. Thanks dude. I tried reflash the board before but using a GUI tool. I’m using OSX 10.11.1 that always unable to load the board with filed to flash message. but the problem now being solved by using terminal.
