Hi!
I own a Chateau LTE12 Router (RBD53G-5HacD2HnD). I’ve just upgraded the firmware of the EG12-EA modem there to the FW Revision EG12EAPAR01A13M4G. And now I have a “SIM card not inserted“ issue. Tried different SIM cards, they all work elsewhere, but not in your Chateau.
Please help me downgrade the firmware back.
May I ask what is the relationship between route and EG12?
This seems to be a third-party product. Maybe you need to burn a specific version. Please provide more information, and whether you can access the USB port of EG12 to send some AT commands,
such as
ATI //query version,
AT+CPIN?//query whether the SIM card is inserted,
AT+CFUN?
BR,
Thanks
For EG12 and Chateau LTE12 i have EG12EAPAR01A15M4G and works.
I’ve found some quick local help to downgrade the FW of the modem. works fine now.
