Hard Reboot with Rear Switch
Install the Latest Factory file for your particular model (9000i or 9000i Local).
All files are numbered.. the higher the number the newer the file.
Current Latest Factory file is V111.
Factory Reset.
Then install the latest 3rd party file. This is the final file you install.
These files are the Net90 files. Latest would be V734 or V742.
AGAIN, be sure to use the appropriate file for your particular model.
Save and Factory Reset.
