How To Disable Some Functions Of USB Port

I am wondering around the internet to learn any method to disable MTP/PTP/all usb stuff except charging.
So, why i want this?
Because i want my device to be secure.
I don't anyone to sneak around and try to go into bootloader or recovery/connection to a pc etc to set my device to make a fresh start/copying data and end my privacy up.
So is there a way to disable those functions?
And if it is possible then what? Will it be secured?
And the big question is that can i enable it through recovery (from adb or moving mobile files) as you know if one has a messed up rom then he/she should have those functions workable.

delete mtpApplication.apk in syste/priv-app and in dev options..deflag debug usb
anyway ...not tried because i don't use pin in LS--but in S6 when phone is locked with pin is not recognized with PC

So will it disable the mobile to connect to a pc through bootloader?

I found this on a web:
.
The most device-compatible way to disable everything is to run this command at startup or set this in your build.prop:
Code:
setprop persist.sys.usb.config none
which is equivalent to charge-only on all Android devices.
That also disables adb. If you use adb regularly, then:
Code:
setprop persist.sys.usb.config adb
will allow adb when developer options are turned on/checked. If you don't use ADB often, I would not recommend it, because setting adb causes my S5 to still recognize in device manager, even when it is locked.
To restore original functionality,
Code:
setprop persist.sys.usb.config mtp,ptp,adb
allows all USB protocols.

ADB offline

I can't seem to get the authorization pop up to allow adb to work. I have usb debugging enabled and adb shows the device as offline when using the command adb devices. Has anyone else experienced this issue before or have any way to fix it?

I am having the same issue. ADB will not work at all with this tablet

Same here
I have the same problem; enabling USB debugging in the Developer Options menu does not seem to have any effect. Closing the settings app and restarting it results in the option being switched "off" again.
This on an unrooted, locked stock device with EMUI version 5.0 / Android 7.0
Weird ....

I work around this by enabling usb debugging, going into another setting menu option, then back to developer options, disabling it, enabling it, adb kill-server, adb devices, trying different combinations and eventually it works.. It's a real pain but eventually it works. Once the computer is trusted I don't need to do this anymore.

Fire 7 2019 app disable including lockscreen ads

I used icebox https://play.google.com/store/apps/details?id=com.catchingnow.icebox&hl=en_US
"Active with simple ADB mode"
froze apps-
Device Setup
DeviceSoftwareOTA
Forced OTA
Special offers
After installing i was getting a pop-ups about adb not connected from Icebox, i uninstalled icebox as this point. Opened package disabler ( https://play.google.com/store/apps/details?id=com.pdp.deviceowner ) to verify they are still disabled . They are disabled still, rebooted multiple times. There may be an easier way, but all i tried from adb didn't work. I hope this helps...

Can you disable via ADB
1. Go to Settings -> Device Options -> About Fire tablet -> Serial Number and tap the several number until the Developer Options is unlocked and press back button
2. After the Developer Options appears under About Fire tablet menu, Go to Developer Options -> USB Debugging and enable it
3. Plug your Fire tablet to your PC, open Command Prompt and approve the USB device
4. Verify the attached devices
Code:
adb devices
5. Let's disable this app including bloatware
Code:
adb shell pm disable --user 0 com.amazon.venezia
adb shell pm disable --user 0 com.amazon.kindle.kso

To activate the device owner from PDP
Code:
adb shell dpm set-device-owner com.pdp.deviceowner/.receivers.AdminReceiver

If your rooted you can easily disable apps, i used this method before rooting. I use package disabler app to easily disable/enable apps with root.

Frustated with Google News Application

As the title says, I'm fed up with the Google News Application. But the thing is., It is installed as a system app and I don't want that- Disable is the only option that exists for me. I've been disabling it everyday. Even I've disabled Auto-Update for that but still it ENABLES by itself and even UPDATES BY ITSELF.
I've even seeked the help of customer care but they told me to visit SERVICE CENTRE and I even did the same. When I visited the service centre, they just Hard resetted my device and I told them that I've done it more than 6 times at home. They started arguing with me thereby accusing me with bad words...
My phone is still under warranty and I don't want to lose it by installing TWRP and rooting it...
Any kind SUGGESTIONS are HEARTLY WELCOME.

Use ADB.
Download ADB from Google to your PC. (Minimal ADB did not work for me, The one from developers.google.com is the one that works for me)
After ADB, Go to settings and about phone, Tap on build number 7 times. Now you will enable developer options.
Go to deverloper options and enable USB debugging. Now connect phone and open cmd from the folder where you installed adb(Just type cmd in the address bar of the folder). Now a black window will open on your PC.
Then type adb devices on your PC. Now there will be a prompt on your phone asking allow access to the PC.
Select yes and then go to your pc and type-
Code:
adb shell
Code:
pm uninstall -k --user0 com.google.android.apps.magazines
Then press enter.
Now Google News will be uninstalled.
(I tested this, And also used this various apps, They work fine. Your OTA will not break and the apps will not come back after an system update also)
Cheers

Okay. Thank you. But it gets only HIDDEN not completely uninstalled. As of I know, I can't uninstall permanently without root access.

Nokia's drivers are the only ones you need to install.
Yes, Using this ADB method will not uninstall this app from the system rather it disables the app for you. But this disabled app will not come back unless you want it too, Not even after OTA.

Honestly speaking, in New to using ADB... But knew sp flash tool and I had thought that both are similar but not.
Are Nokia drivers are same as Google drivers?
Can you share me the step by step procedure is you enough time now, sir?
I just downloaded latest usb driver from developer.android.com

Hey Guys let me tell you I do get automatic installation (via Google Play) for the Google News app (yes frustrating ) but what I did is uninstalled updates emptied it's data and forced stop / disabled it.
As of this comment I do get automatic installation request via Google Play but Google News doesn't updates. This worked for me.

Lenovo Tab M8 -- HD and FHD How to debloat/remove Apps that you can't uninstall/disable -- Without ROOT

This guide is how I removed apps on my Lenovo M8 FHD, but applies to almost all Android devices.
(Root is NOT needed)
Things needed:
ADB shell and a Windows computer, an android Apk Analyzer app (I use "Apk Analyzer" from the Play Store).
Enable Developer options & USB Debugging:
Lenovo M8 FHD -- > Settings -> System -> About Tablet -> Tap on "Build number" multiple times. #A pop up should state you are now a developer.
Settings -> System -> Developer options
Scroll down and enable "USB Debugging"
Connect tablet/device to Windows PC with ADB/Fastboot installed (plenty of guides on XDA available here.)
Open an Administrator Command Prompt. (Right click on CMD and select Run as Administrator).
Type the following:
adb devices
A pop up on your device should ask if you want to allow it USB Debugging access, check always allow and select yes.
adb shell
You should now be at a "$" prompt
Using "Apk Analyzer" on your tablet/device search for the app you are looking to remove. (Example search for Lenovo)
On the PC/ADB Shell issue:
pm uninstall -k --user 0 com.APPLICATIONNAME
The APPLICATIONNAME is found using the "Apk Analyzer" app...
The result shown on the screen should be success.
The apps you uninstalled using ADB shell pm uninstall -k --user 0, were only removed for the current user (user 0). If someone else uses your phone with a guest account, all the removed apps will still be available to him.
You can do this for any app that you want, but be warned you can inadvertently delete apps that you need...
How to re-install an app:
cmd package install-exsisting com.APPLICATIONNAME
Let me know if you need help, or have any recommendations.
