Have a KV I just got a few days ago, want to disable the touchscreen to prevent accidental pageturns.
My KV is on 5.8.9.2 , and when I try to put the factory firmware on the device it wont take. I go to the menu and update is grayed out. I plugged the device back into my PC and the file had disappeared.
It looked like JB by serial would be an option for me, however I'm very hesitant to operate on my device that is brand new.
Is there anything else I am missing? Some other software JB method for the KV and this firmware version?
