MetaMotion R broke
Hello. I have discovered several MetaMotion R devices I haven't been using for some time have broken. They are not visible in MetaBase app. Some of them probably broke when I was updating firmware to 1.4.1 on them. There were cases when the device disconnected during firmware update and then failed to reconnect. I put them away for some time thinking they would come back to life later but apparently they haven't. What can I do to repair/reset/unbrick them?
