Hey all,
I am still learning more about the civic world since getting my car last week. I was looking into something called Honda Hack that is possible on the 10th Gen Civics. I did some research and it appears the exploit worked by:
  • accessing a hidden menu
  • disabling android restriction
  • accessing the browser and navigating to www.autohack.org/root to activate the payload to root your head unit
However, it appears the Disable Android Restriction, and quite possibly the browser apk itself is gone. One thing I did note is the new hidden menu I found allows you to activate ADB over USB, so there is a potential to just sideload a browser apk, launch it, and then try to use HondaHack or other methods to root the very outdated Android 8.1.0 OS.

This thread is just a catalog for what I discover on my quest to root / hack the new 11th gen head unit. In following posts I will post some screenshots / videos I took of the new menus and options that I found

The original Honda Hack thread for a 2017 Civic can be found on the XDA Developer forums.

Here are some screenshots and methods to access the two hidden screens I have found:

First Hidden Screen (Diagnosis Menu):
Similar to what was used on the 10th Gens: hold HOME + POWER + BACK:

That brings you to a screen that looks like this:

From this screen (or from the Detailed Information & Setting screen), Hold BACK + POWER + FORWARD for about 5 seconds for a new hidden menu:

The thing to note here, I think, is the USB mode. It allows you to turn on ADB Mode through the USB port:

It leads me to believe this may be the route that is needed to take in order to take admin-level control over the device.

Here is a video version of showing how to get into the menus as well:

The other important thing I mentioned: lack of a browser period.
If you navigate to General Settings > System > Developer Options > Developer Option > Inactive Apps, it shows a listing of all the apps (presumably) and notably missing in the list is any reference to Browser, Chrome, Firefox. The only thing I see is a WebviewBrowserTester.

Here is a video on that:

With the above ADB Debug through USB method, my thought process is to snag a copy of a browser like Firefox, install and launch it.
Bash:
# Would require a computer or device with ADB and the APK installed
adb install org.mozilla.firefox.apk
# After installing to the head unit, launch it via this command
adb shell am start -n org.mozilla.firefox/org.mozilla.gecko.BrowserApp
I hope to test this out sometime soon!

So I tried several combinations of setting the USB mode to ADB mode, and also going into General Settings > System > Developer Options > Developer Option and enabling USB debugging. However no matter what I tried, my computer would not connect to the head unit. I also noticed that the ADB mode usb mode seemed to just turn off power completely to the port and nothing worked.

I did find another hidden menu like the 10th gen civics had, but the Disable Android Restriction Button is gone from that menu as well.

After holding HOME + POWER + BACK to get into the Diagnosis menu, click the bottom button for Detailed Information & Setting.

Now on the Detailed Information & Setting screen, hold the HOME button for about 5 seconds.

That takes you to the Developer Diagnosis Menu. I tried checking every single menu in here but the Special function setting stuck out to me from watching videos on the 19-21 Civic Honda Hack videos.

However clicking it just nets you this:

And clicking that button just shows you a toggle switch.

I tried holding some combination of buttons on this screen but nothing worked there.

I'm leaving this thread up for now in case anyone else takes on this endeavor for Honda Hack in 11th Gen. But it does not look promising as of yet.
