Update on the password reset. So, no depot trip needed. After case opened on MyView, a "password of the day" resent binary file was sent. It is only good for 1 day, read the radio with CPS, upload provided binary file, and read/write password was removed. Our tech still swears he didn't put in anything but a known password, so we can't confirm the root cause, but the MSI provided fix resolved it.
FWIW MSI will ONLY provide this to the documented, lawful owner of the radio.
Firmware has been stable and having the RSSI display in dBM is nice for us radio folks.
