A strange thing this weekend. I had received a new SD card to update the microRendu to the new V2.5 firmware. Followed the update instructions, it did not work, no network light on the mR, and I could not pick it up on the network. Worried that I had done something stupid and junked the mR, I reversed the process and reinstalled the old SD card. This was fine, the mR was back working as it should on the old V2.3 firmware. I contacted Sonore who advised 'We have a unit with this behaviour coming in so we can have a closer look.' ... ' We should know more late next week.' They also stated that it was unlikely that a new SD card would solve the issue. So it looks a bit like some mR's are refusing to update for some reason, which is intriguing.
