Hello,
Wondered around with my chinese made head unit settings and tried to find developer options, and under factory setting there is build.version. tapped it seven times and i get menu which is in picture. Ran menu thru translator and got following:
System emergency settings
Switch to debug version
Upgrading the OS package
I have tried to connect unit to my laptop with usb a-a cable for usb debugging but no luck. adb on my laptop do not reconize unit at all. Any ideas if these options have anything to do with developer options or usb debugging?

If you cannot connect your nexus 7 with 4.2 jellybean to your pc through usb i might have the fix. it will usually connect through camera mode without any problems, but you cant get to your other files, do this, start Debugging Mode by----
Go into Settings
Go to About Tablet
Press where it says Build Number at least 7 times, it will then give you developer options which is key to it all.
Then in system settings open Developer Options and enable USB Debugging,
Connect to PC and switch off of the camera usb thing.
I have a Galaxy S4 that is running Android 4.4 and I am trying to activate the 'USB debugging' option but it appears to be greyed out along with the 'Take Bug Report'. These and other options under the Debugging tab are the only things that are greyed out. I am pretty sure I have the newest driver software for my phone that I got from the Samsung website. I know that I can only turn the USB debugging on when the phone is not connected to the computer and I have my phone set to connect by MTP. Ask if you need any more info.
Hi
i can't find the option to enable wifi debug, only usb. I'm trying to connect but is refused.
Thanks.
I solve this with adb-Master
Thanks!
I'm very late to this thread, but luckily, as of about Android 11 and up, adb works over wi-fi (without USB) on non-rooted Android phones via Developer options Wireless debugging switches.
Hi
i cant connect my OP5 ( two days ago it worked) to my laptop
changed cables and usb ports with not success
this is what i am getting
"Currently, this hardware device is not connected to the computer. (Code 45)"
and after this i dont see even the yellow mark on the device manager
please assist

Sounds to me like an driver issue. Just install the platform tools again, reboot pc and connect your phone again. Or enable ADB and USB debugging again in Developers Options and reboot device.

I just dropped my phone and the screen no longer works but the phone does. I plugged it into my computer but I remember that when I have done that in the past I had to change it from charging mode to MTP mode using the screen. Is there anyway to change the phone to MTP mode without using the screen so I can get my files off of the phone?
Thanks
Was USB debugging enabled before? and if yes have you authorized your computer for the phone before?
