TCL Flip 2, model T408DL, KaiOS 3? debut mode possible, but no cannot "Enable developer options"

[rex]

Got this device: TCL Flip 2, model T408DL, KaiOS 3?
From my research, it seems that everyone say KaiOS 3 is impossible to enter debug mode, BUT, I was able to.
To enter debug mode, on phone, dial:
*#*#33284#*#*
33284=debug on the numpad

This method does not work for TCL Flip 2: https://w2d.bananahackers.net/

On phone notifications, click on "USB debugging connected", it say "Enable developer options first". I do not know how to do that. I think this is preventing WebIDE below from connecting to it?

https://developer.android.com/tools/releases/platform-tools
Click "Download SDK Platform-Tools for Windows"
Unzip the file. Open CMD, go to that folder.
Connect phone to PC
In CMD Run:
adb devices

It will say "Daemon not running: starting now at tcp:5037".

On phone, there will be a pop up asking you to allow USB connection.
cmd show it can see the phone.

I am ABLE to see the device using FirefoxPortable_84.0.2_English.paf.
After opening, go to "Web Developer" -> "Remote Debugging". Then click "Enable USB Devices".
You can then see the TCL device, but it show "Waiting for browser", and just stuck there.

I tried connecting with localhost:6000 or 5037, but cannot connect.

Question on the remote connection from firefox. If I want to connect, do I need to run:
adb forward tcp:5037 localfilesystem:/data/local/debugger-socket

If I run that, adb gave me error. Online example tend to show port 6000, is that b/c their daemon is running on 6000? Mine started at 5037, so I used 5037.

it is not kaios, it is android 11. That phone can be rooted, and android APK's can be installed, and USB Debugging works, and system apps can be removed, and key mappings can be changed, and you can get a virtual mouse on it and much more. forums.apps4flip.com has guides on that.
