After 1 year without a problem I get a "IMEI + CME ERROR: 23" since yesterday. What I tried so far:

- Reboot
- Update Firmware and keep settings
- Update Firmware without keeping settings
- Reset-Button on device
- Tried 2 different SIM-cards => everytime the same error
- Checked original SIM-card in phone (working!)

A screenshot can be found here:

I checked the forum and there is a similar error reported on a RUT955:
https://community.teltonika-networks.com/21147/rut955-mobile-connection-device-information-show-imei-error

But as I have a RUT850, I opened a new thread.

I researched the knowledge base and the web. The CME ERROR 23 seems to be memory related.

Anyone having/solved the same issue?

Hi,

Could you please try going to CLI, logging in and typing firstboot?

This will initiate the same reset sequence, but maybe it will help.

Also, what I would suggest is updating the firmware, cause I see you have older than the latest one right now.

Please try updating it without keeping the settings.

Hi,

thanks for the reply. Unfortunately firstboot didn't help. I updated the firmware to 1.04 earlier (same CME error) but as I am using a multisim (2 simcards under the same number) and I couldn't find the setting to not answer/reject calls, I had to revert to 1.03.5 (disable Services -> SMS Utilities -> Call Utilities -> Reject unrecognized incoming calls)

Regards,
Flip

Do you have not a multi-SIM card to test device on?

Yes, I  tried a non multisim yesterday - same problem.... I also did a reverse check - putting the multisim (which I successfully used for more than 1 year now) into 2 other devices (phone/tablet) to verify if that works... sim card is working...

Could you send me your troubleshoot file via private message? Make sure that error 23 happened and you didn't reboot the device after it.

Sure! Just sent you the PM.
