I own 2 units. 5000nex & 5100nex.
The 5000nex is working wonders.
The 5100nex is lagging & crashing so often it's pathetic.
What I have tried:
- reset from the settings (gear icon). no luck.
- reset from the testmode through a USB stick. no luck
How can I fully re-install the OS? I wonder if it could be a software problem
