EHS6T -JRC Issues | Telit Cinterion IoT Developer Community

I have two EHS6T which have JRC issues:
Modem 1: With a HyperTerminal connection to the serial port, on power up I get:
The ^SYSLOADING would indicate MEM is started, but I am not getting ^SYSSTARTING thus indicating the JRC is not being loaded.
The ‘O’ is just a polling command to external equipment attached to the ASC0 port.
I have tried ‘EHSx gwinswup V03001 arn00000014 to update the Firmware, depending on flags set I get the following error messages:
· With No Autostart and No Firmware in Module : Error: cannot send update command.
· With nothing selected: Warning AT Command mode not selected.
Failed to set userware autostart mode to false.
Since there is no JRC I cannot use any AT command to interrogate the modem, or update any settings.
The modem is visible in Windows Explorer in Module Disk(A:) along with my MIDlet.
The modem was previously working, and the problem appeared after stopping and removing the MIDlet o that I could update the MIDlet.
· stopping the MIDlet, at^scfg=”Userware/Autostat”,”,””,”0”
This previously also worked.
With a USB connection to the EHS6T and in Windows Explorer the modem is visible via Module Disk (A:), and I can see previous *.jad, *.jar files.
With a HyperTerminal connection to the ASC0 com port I get no responses, ^SYSLOADING, ^SYSSTART, from the modem on power-up, and doesn’t respond to user AT commands.
I tried to do a Firmware update on this modem, but again on running sgwinswup I get the same error messages as for modem 1 and thus I am unable to get an installed JRC.
I would appreciate any help in resolving the above issues with both of the modems.
