I just bought 3 more Panda’s (great little rigs) but one seems to be DOA unless there is something else I could try. After a half dozen try’s I got into the bootloader through Tera Term but it will not load the new firmware. Xmodem 1k starts but never sends a byte. It gives me a serial number of 0, hardware version 10 and a not so cryptic message saying bad fimware but refuses to accept new firmware, even though it says it erased the bad one.
Any suggestions or do I return it?
