EC25-EUX Firmware Update

I have mny EC25-EUX modules with firmware EC25EUXGAR08A07M1G, I need the latest firmware for this module.

hi,
Do you still need a new firmware version?

Yes, with ipv6 address no fetching with current version, but same SIM work’s on another EC25-E. Would like to check with new firmware.

How do I recover a device (EC25EUXGA-128-SGNS) what is in QDL mode?. What software and firmware do I need?
