I have a jp5s tablet running android 4.2.2. It is a prison issued tablet. USB debugging is not enabled, and you can't enable devlopers options. Bluetooth works but app installation is blocked for security purposes. And the ability to allow unknown sources is disabled. Recovery mode only has reboot now. There is no fastboot so adb on windows will not connect. My only idea is maybe a picture or video file that runs a script to allow USB debugging, or installs an apk(a file manager). Also I'll pay for one that will set my devices year back to 2011 or so. Please any help or advice. Maybe a windows program that will force connect adb somehow.
Yeah you can go to settings but its very limited, pressing build number only brings up a list of installed apps.
Nothing google at all its a prison tablet that's the issue I want to install apps

Hi , can you post video on YT in order to see what is actually happening your device.
Yes I do, I need to install a 3rd party app

Hi all. What I need is a way to control Android device (s) from PC via Wi-Fi. I found a lot of apps (and Desktop programs) to do it, but I didn't found a way to View OR control the Android device WITHOUT ROOT. I work on the company which asked me to find a way to do this without root with their Android devices. After googling a lot I started to think that where is no way to do this, because either way I need to root them . Is it true or maybe there is somewhere an app which could do this? It doesn't care if it's paid or not.
I have downloaded and tester these apps:
MyMobiler - Doesn't work because when I restart Android device, app doesn't start WiFi, just keyboard mode only. I need that when the app starts it should run itself and start WiFi automatically.
VMLite VNC Server - Don't know why but it didn't worked for me. Just cannot start server from the browser.
Thank you for any responses and appreciate any help.
What error messages do you get from vmlite vnc server? Make sure you enable USB debugging. We have tens of thousands of users using our app, and your device should work.
Well, actually now I tried to launch VMLite VNC one more time and IT WORKED (don't know how, because earlier I tried it and I was unable to enter to VNC Viewer in the Browser). So yeah, in this case it works perfectly now, but I just realized, that I have no way of connected more Android devices. Because what I need to do is to connect multiple Android devices to computer with USB (as I understand it's required for the first time) and when use it with WiFi. For now I see that I only capable of connecting single Android device with desktop program and everytime I want to connect to Android deice from computer, I need to connect it via USB (where is no way to save Android devices to use it any time I want to via WiFi). Or am I wrong? And it is a problem because in my company all Android devices are far away from each other. Anyway, thank your for such an awesome app, I really don't know how it is capable of connecting to my Android device WITHOUT ROOT (because I found like 10 apps, read a lot of forums, and every solution was with ROOTED devices, I am very interseting of the actual app functionality), but thank you.
You can connect to multiple devices using multiple USB cables. There is a drop down list to display devices, and you choose one by one to start the server. Alternatively, you can write some scripts to auto start the vnc servers.
There are quite some testing companies using our app this way to automate regression tests.

Can I get more information about it? Thank you.
Basically you can automate the starting process using adb command:
adb shell "am start -a android.intent.action.MAIN -n com.vmlite.vncserver/.MainActivity"
adb shell /data/data/com.vmlite.vncserver/files/vmlitevncserver

Thank you for this script (it's very cool, I didn't know this kind of stuff before), but it requires USB connection as well.
I googled a few things and found this app - ADB Wireless (no-root) on Google Play Store. Basically it connects ADB via WiFi and I don't need no USB cable and connection with it. But VMLite Android App Controller program on my Desktop doesn't recognize it (it requires USB connection). Can I actually connect Android device with PC with this method or I am missing something and there is no way of doing it with this method? Thank you (I promise, this is the last question from me, no more dumb questions).
I don't think it will work for you. You mentioned your android device will reboot, right?
If your device gets rebooted, you will have to use a USB connection to a PC. the ADB wireless app has same requirement.
Steps to get it working: (from ADB Wireless app page)
1. Enable USB Debugging on your phone.
2. Connect your phone via usb cable to your PC.
3. Run adb tcpip 5555.
4. Run ADB Wireless (no root).
5. Connect to the IP address.

What's right. It needs to connect my phone via USB. But I thought that maybe there is a way to automate this process, I mean maybe there is a solution to TURN DEBUGGING MODE between phone and pc programs via WiFi connection (not USB) and communicate with VMLite VNC Server program on startup. Either way, again, thank you for your software (app). I will say to my boss that we need to stay where we are at the moment. It's just awesome to have an app which doesn't require ROOT.
Hi, I'm new to the N9, have had the tablet about a week. I have tried connecting it to my windows 7 Pc and the N9 isn't recognized. I have tried all the basics, all drivers are current, set tablet to mtp, and not found. I have connected to a friend's Windows 10 PC and the N9 is found immediately. My N9 is a wifi only device, non rooted. I have 2 other Android devices that my W7 PC finds with no issue. Anyone else experience this, and or have any suggestions on how to fix this issue ? Not looking to root at this point. Any help and guidance would be greatly appreciated
I think there are many threads about this problem. Nexus Root Toolkit has a driver installation feature.
If you were starting from scratch I'd delete any unknown "tablet/usb" devices in Device Manager - look for the also delete drivers option.
Google's W7 installation instructions are here http://developer.android.com/tools/extras/oem-usb.html#Win7
On this page http://developer.android.com/sdk/win-usb.html is a link to download a zip file of the drivers (not the full SDK package) Click here to download the latest Google USB Driver ZIP file.
This software http://www.nirsoft.net/utils/usb_devices_view.html is possibly better than device manager in deleting drivers
In some cases, you need to enable ADB on your N9 before plugging it into your PC (Settings -> Developer Options -> Android Debugging).

Thank you for your help, I had already tried all of this, but tried once more in case a step was missed. Every other Android device I have, or had never gave me an issue like this. The 2 android phones I have connect to pc without a problem, I am at a loss, lol.
When deleting drivers, should I have deleted all drivers for all devices, or just the ones installed from N9 ? Thanks again for your help

I've not got access to a Windows 7 PC. Does this page help http://www.topnotchtablets.com/FixUSBproblems
A basic one. I don't think it's relevant until you have a connection. Do you know that the N9 USB connection defaults to "charging only" and you need to pull down the notification menu to enable MTP to see the device contents
In USBDeview
Expand the window there are a lot more columns
There is a "connected" y/n column. I'm not certain that this works as expected, I can connect a tablet and despite an F5 refresh or a restart of the program it will stay a "No"
Look at the VendorId column AFAIK everything Google Nexus related has an ID of "18D1"
Have tried to establish what, if anything pops up in Device Manager when you plug in the N9 so you can disable it? Nirsoft have a program http://www.nirsoft.net/utils/device_manager_view.html that gives a table view of all devices - no clicking to expand trees

Thank you for your help I greatly appreciated it. After trying pretty much everything, I decided to see if the ruu's for my two phones would run on W10. They did, so I then proceeded to update my W7 to W10. N9 communicates perfectly now with my PC. Thank you
I currently have 5.1.1 installed on my honor 5x and am able to use adb automatically without accepting an RSA prompt (have installed twrp, rooted, etc.) but when I dload a MM stock rom and use usb debugging it is unauthorized and I get no RSA prompt I've even gone as far as to delete /data/misc/adb from my device and adbkey.pub from my desktop but there is still no pop up authorization in MM
Developer options -> Revoke authorisation (something like that), replug. If that doesn't help, change connection mode to file transfer and try again.

I actually don't have a "revoke authorization" button below usb debugging, odd I know but I've tried all those options to no avail

Tried toggling the debugging switch? I had issues like these on one of my previous devices, but usually these were fixed with a simple port change or debug off/on switch, if revoke->replug didn't work.
Have you checked drivers, or if dmesg says something about the device, if you're on Linux? Sometimes even running multiple adb instances (like one from terminal and one from Android Studio, for example) can cause this behviour.

I want to control my android device loaded with lineageos 8.1 remotely from my laptop from the browser. I have tried airdroid, but i am not able to use the remote control feature when i am offline, it only works over the internet, is there any fix for this? also please suggest any alternatives. I have root access using magisk.

Definitely want to be using scrcpy. It uses adb as it's connection method. So if you can wifi adb to your devices you can remote control it.
If you need sound, it gets slightly more cumbersome. But sndcpy works well in tangent.

Some phones have an option in Developer settings. It normally explicitly says wifi adb. If you don't have the option, you'll need a root app or elevated terminal to activate it.
The app is faster to use if in a normal context.
Find on on the playstore. Just search wifi adb.
Then on your computers terminal, which has adb installed properly, type "adb connect {your phone's ip address}"
Once it successfully prompts and you accept the connection on your phone you are ready to use scrcpy.
You can find tutorials on how to install both adb and scrcpy.
But the most user friendly, if on widows, is to first install a repository called Choco. Again, look up how to do so.
Then, simply type these commends in an administrative PowerShell:
choco install adb -y
choco install scrcpy -y
If all of this seems overly complicated. It is a one time setup. And all of these tools are excellent to have in the future if you are into Android and software.
After these steps are completed, rember you first have to establish an adb connection and then type scrcpy into your terminal.
Ok, Thanks a lot!!!!

- Download scrcpy.zip
- Unzip to the dir of your choice
- On your phone: Developer settings --> Enable USB Debugging
- Connect with a cable
- Run scrcpy-noconsole.vbs
Should work (also for android 12)
If you want to use this over IP, let us know

Oeps, the previous scrcpy.zip contains convctctytdl.exe ... you won't need this:
This is used to convert all youtube files (movie, list, etc...) to mp3
You can delete this file
This is the windows x64 version
You don't need internet as your phone is connected with a cable
Thank you everyone for your help!!!
Scrcpy is successfully installed and is working fine!!!
I took help from this forum and the official GitHub repo https://github.com/Genymobile/scrcpy
Thanks everyone
i have another request, please help!

Do you have developer options enabled? Since I've enabled them the only way I can get usb transfer to work is with developer options enabled. If I turn it off, I can't connect to my PC.
yes developer is on i cant even get the transfer option to show in status bar dev option on or off? do we need to install anything for win10?

Usually, it's plug-and-play, so you wouldn't need any dedicated drivers for this.
Have you double-checked if your cable and ports (on the PC) are OK?
Can you try enabling ADB Debug from the developers option and see if the PC recognizes it in ADB mode?
Finally i changed to another usb cable got the option this time but then had to go to device manager and update the driver mtp choose from list and all set up working now.
jutleyTry deleting the old device from your Google Account.
Leave only the new phone in the profile.
Reboot and try logging into the S23 Ultra computer again.
That's how it worked for me.
Good luck !
