Until this week when helping a friend setup his new OS4 Pro, I've not seen this issue. It seems when his OS4 gets stuck in this mode, the only way to exit is to login to the OS4 via computer and select a new profile. The OS4 is stuck in this special connector mode, even if power cycled.
This seems to happen when pressing the power button 3 times to unlink and if he is in a cross-mode profile. It doesn't seem to happen when he's in DMR and using the power button to unlink. When the issue happens, the LED starts alternating green/orange. It's a real mess when this happens because he doesn't have a good understanding of the OS4 operation.
Also, when I assisted him, we initialized his OS4 Pro with his credentials. Then imported my DMR/YSF/FCS/D-Star profiles and edited each for his credentials and saved them.
Now, if his OS4 gets stuck in special connector mode, my credentials appear - however, the profiles all have his credentials. Where are my credentials coming from when special connector is activated?
I've never seen any of this behavior on my OS4 Pro. We are both on firmware 43 stable.
