[GUIDE] How to enter developer mode on 2017 Honda Civic (and now root & install apps)
Honda has changed the password to enter the developer mode in new vehicle models so the old method described in this thread may not work any longer. If you have difficulty entering the developer mode or do not have a laptop, you may consider trying the new web based installation (paid service). The new method supports almost all Honda vehicles including Civic, CR-V, Accord, Pilot, Ridgeline and Clarity. For more information please refer to: http://autohack.org.

Now we can root the head unit and install apps. Below are the detailed steps, please use at your own risk.
Detailed steps: 1. Enter developer mode and enable USB debugging.
Go to HOME > Settings > System > Detail information.
In the Android Settings window, click About.
Click the Build Number seven times exactly.
Now you will see the Please enter a passcord prompt.
Click the top 4 items in order 1, 4, 2, 3 and you should unlock the developer mode.
Go into Android Settings > Developer options and enable USB debugging.
2. Change the USB role of the head unit from Host to Device.
Press the power, menu, and brightness button at once, and hold until you enter a new menu with two options.
Click the bottom option called Detail Information & Settings.
Now hold the MENU key to enter another menu.
Then Hold the HOME key to enter the last menu. You should first hear two consecutive beeps and then one final beep.
Lastly, change the role of USB Port from Host to Device.
Now connect your laptop to the front Android Auto/CarPlay Port using the USB A to A cable.
3. Run the One Click Root
Disable your anti-virus and/or anti-malware programs before continue.
These are all my edits. I thought I would share them with you and the community. I'm sure you could integrate all the build.prop additions in your installer. I think if you dig around you will be able to script all of the things kernel adiutor is doing with a 5 second delay after boot. Then there would be no need for the app anymore. I hope this helps to make a more fluid experiance for all.
(Edit build.prop) (located in root/system/)
(Only use root explorer)(it is the easiest method because you cannot alter or delete values with kernel adiutor)
(Long press on the file, then hit menu and select open in text editor)
(Add these lines exactly as posted bottom or end of the file)
(After inputting and altering press menu then save, then press menu then save and exit. You will see that root explorer made a file named build.bak this is your original build prop that they changed the extension on. If you wanted to revert back you could rename the extension to .prop and replace the modded one)(you would also need to make sure the permissions were the same after renaming build.bak to build.prop if going back)
(After completion reboot your device for the new build prop to take effect)
(Now for kernel adiutor app - download from Google play on your car) (make sure to tick apply on boot to all things)
1.) Go to CPU and change cpu governor to Userspace (helps so reduse wear on system)
2.) Go to thermal and turn thermald on (prevents cpu overheating)
3.) Go to i/0 and change external storage read ahead to 1024 (makes external storage load faster)
4.) Go to low memory killer use slider to adjust settings:
5.) Go to entropy and adjust both read and write values to 256 (this is how much is preloaded for memory so the system doesn't bind)
6.) Go to misc and change your host name to something shorter (I renamed mine "Car") (Shorter names typically connect up faster)
7.) Go to settings and change apply duration to 5 seconds after boot.
( * I take no credit if you kill your dog or burn your house down. These settings work fine for me and I am willing to risk my edits, it's your choice to do this or not. I am not accountable for anyone elses actions. I hope this helps the community here * )
* Ps if owners do not know, long pressing the home button will access recent apps so you can close running apps or switch between them easier.
Attached here is the stand alone apk made with Tasker. Simply install the apk, allow root permissions, and let it run. This changes DSP to Flat / Eq Off. You'll have to run the program every time you start the car, I have a shortcut on my home screen.
Thanks to @panchox for the initial logcat finding. I tried all kinds of stuff with kmod ect. and found this was the simplest solution. This apk is just like the video @shinemonmond posted but, I made it myself because I got sick of waiting for others to post this.
With out further delay here it is, may your ears rejoice!
Leave me a thanks thumbs up if this has helped you.
