MR6500 - unsupported firmware

[eliej15]

Hello,

I would need your help because we used credits on an unsupported firmware, getting error AT command...

Will you please be able to refund the credits? We will secure a different device to use it on.
Additionally, we are looking for modifying at least 2-3 devices. Would you be able to provide any help downgrading the firmware on this device?

Thank you in advance.

Credits were returned, please check supported models or tutorials or contact us to make sure the device and its firmware can be unlocked. Sadly we do not have any information that could help with downgrades of Netgear devices.

Can you also recommend couple other options other than Netgear that could be utilized in the same way?

That is operate as a mobile data on the carrier network?

No, sorry, we do not know alternatives for devices, we do not use them.
