Hello,

I have a Quectel RG502Q-EA module installed in my device (MikroTik Chateau 5G ax).
I would like to request the latest official firmware version: RG502QEAAAR13A03M4G_02.004.02.004.

Please provide the download link and the QFlash tool if necessary.

Thank you very much!

Hi Sir

Could you please share your current firmware version? Much appreciation.

I have already installed the latest version, Reason for request for firmware the modem consistently reports a CFUN=7 status, indicating that the radio module is disabled.
I have performed diagnostics using AT commands:

  • AT+CFUN? → +CFUN: 7
  • AT+CPIN? → +CPIN: READY
  • AT+CGSN → IMEI successfully returned (valid format).
  • ATI → Reports correct model: RG502Q-EA with firmware version RG502QEAAAR13A03M4G.

Attempts to manually enable the radio function using AT+CFUN=1 result in +CME ERROR: phone failure.
Despite the SIM card being recognized and the IMEI being valid, the modem remains stuck in CFUN=7.

Given that the latest available firmware is already installed,
please advise whether this issue can be resolved,
or if I should proceed through the seller Because the device was bought a couple days ago and was supplied out of the box with this problem.

Thank you for your assistance.

Dear @VTheory
It seems the QCN was lost during upgrade.
Do you backup it before upgrade? If not, you can contact with your supplier about this.

I haven’t QCN backup, as I didn’t modify or update the modem.
It was already in this condition. I will contact the supplier for recovery.
Thank you for your help.
