Failed firmware upgrade on ELS61-E2 | Telit Cinterion IoT Developer Community

July 13, 2017 - 10:50am, 2544 views

I have recently attempted flashing the firmware on the connect shield.  I have access to the extranet downloads and found els61-us_e_gwinswup_rev01.000_arn0001400 which is a self-contained firmware update utility.  

The process appeared to be going normally but the utility reported having failed after a number of minutes.

The USB port is not enumerating but connecting via the TTL serial port it is outputting a continuous string of ^SYSLOADING every second or so and is unable to respond to any commands or the firmware update utility.

Could anyone suggest how to recover this module please?
