RM500Q-GL - CFUN? output 5 since update

Hi,
we can’t change the status of CFUN since we updated the firmware to “RM500QGLABR10A03M4G”

AT+QRFTESTMODE=0 as suggested here What does +CFUN: 5 mean? is not working either

we are using the RMU500-EK EVB-Kit with a RM500Q-GL module

could someone help us?
regards

Dear Sir,
Your sample is too old, please contact your sales or distributor to get new modules. Thanks!

thank you peter for your swift answer. i am not exactly sure what you mean with “sample is too old”? do you mean the RM500Q-GL module or the dev kit?
we also have a PCIECARDEVB-KIT (https://www.tekmodul.de/produkt/quectel-rm500q-5g-evaluation-kit/) with a different RM500Q-GL module here, that is still running the firmware “RM500QGLABR10A02M4G”

thanks
Christian

Dear Christian,
I mean module, please use our MP module to test instead.
By the way, the latest firmware version is R11 series. Thanks!
