Hello,

I read that you cannot flash new firmware to an RM521F-GL engineering sample?
Is this true?
I was sold an engineering sample module in what was advertised as a new retail router, sigh…

Dear @buggz
Currently, RM521F is engineer sample.
If the module achieve MP, the engineer sample can’t flash the MP firmware.
