After reading Simon's suggestion to delete the DJI GO app,
I solved this issue this morning in 15 minutes.
My Master was already upgraded with my Samsung Galaxy Tab S2.
I use my Samsung Galaxy S5 cell on my slave . I uninstalled my DJI Go app on my S5, waited 2 minutes then re-installed the GO APP via the Google app store.
I then turn on the Slave Transmitter only ans the the S5.
The update required message was there. I did the update which took about 4 minutes. Shut off the Slave and S5. Re-started both and got the red led with the error and beeping. I shut bothe down again. Restarted wih out the error. Shur down both again.
I then turned the Master on then the Tablet then the Inspire. After confirming Master and Inspire operating normally I turned on the Slave and the S5. I had a picture on the S5 but no control of camera. I had to reset the Slave as "Slave".
Remembering that the Controllers return to default I reset my Slave under the "Custom" settings that I prefer for my Slave. I then did the search for Master and put in the master name and pass code.
The final thing if I recall correctly was to request control from the Master from the Slave.
It appears everything is working as normal but I have not taken a flight yet.
