EHS-5: bricked after aborted firmware upgrade | Thales IoT Developer Community

April 11, 2018 - 11:18am, 1317 views

Hi!

I have one EHS-5-based device bricked after gWinSwup cancelled by accident.

I've tried to use "No Firmware in Module" checkbox, and it appears to work, but it fails everytime after flashing some blocks (over 200). Is there any other way to reflash the failing device?

BTW, does it mean, that flashing with AT^SFDL can also make a device unbootable, if device is powered off during the operation? I assume there is only a single firmware image in Flash... 

Below is the relevant log part:
