50S not powering on after battery replacement

After replacing the battery, I found that the unit will power on only once when you separate the boards internally. 

I can connect to it and has the latest firmware and battery is at 100%. 

The unit will function as suppose to with mess, bluetooth audio. 

Once you turn it off it will not power back on until you disconnect the boards.

Have done 2-5 sec, 10 sec resets and still nothing.  If the 10 sec reset is suppose to take it back to factory wouldn't the setting all change? This unit will not do that. 

This has to be a software issue that did not get written/loaded correctly. 

Does anyone have any ideas?
