As above.
You'll need ADB active on the phone.
And a new / updated version of the ADB drivers / tools on your desktop.
Also, you will get a dialog prompt on the phone to confirm a security encrypted key (to allow ADB between your desktop and your phone)
This is something Google introduced on 4.1 (I think) which, if is not set, will end in a "devices not found" when trying to use ADB

Revoke all USB authorisation.
Try reconnecting.
And authorize when prompted!
If it doesnt work!
Also Please post Does your device show up in device manager? IF yes by what name? Is there an ADB Interface?

How to enable USB debuggin with broken touchscreen?

Hi
I have a old nexus with broken touchscreen . I want to use it via mirror on pc.
unfortunatly USB debuggin wasn't enable so i can't install any app.
any tips?
thanks
PS: i saw many use usb adapter to connect a mouse but i don't have it
EDIT: right now i just need a rom/kernel with USB debugging mode enabled by default

the screen still works , only the touch screen is broken
power , and volume bottons still work
the device is rooted

If it's only installing apps you could install them via recovery. (as zip)
Or you could check for a cheap replacement touchscreen.

thanks for the answer!
sorry i forgot to mention that i need USB debuggin for make the app works correctly.
I'm trying now to find out what rom i have installed and maybe then find a kernel with OTG support . (yes i found a otg cable )
i'm not a expert of rooting

I think google has an app called voice control. Not sure how operational it is though. Supposedly you can control the entire system via voice.

i need to unlock the phone and tap on the widget "search" to start voice command .
I think the best way is to find a way to enable OTG and then use a usb mouse

Boot into Recovery and mount*Data*partition.
Open a shell on PC and type:
adb pull /data/property/persist.sys.usb.config ~/
Repace*~/*with home directory of your OS.
Open that file in a text editor and you would possibly see*mtp*written there. Change it to*mtp,adb.
Note that sometimes Android doesn't understand the text file changes if the line terminator is "DOS Terminators" which Notepad would probably do on Windows (mine is Linux so no issue here).
In that case, I would suggest not using*adb pullbut doing:
adb shell echo 'mtp,adb' > /data/property/persist.sys.usb.config
You may verify that the*echo*command overwrote the file by using:
adb pull /data/property/persist.sys.usb.config ~/
and seeing the file's content in some text editor.
Unmount*Data*and reboot into Android OS. USB Debugging would probably be enabled.

i tryed
1) i went in recovery mode
2) i connect via usb the nexus4 to my pc
3)went in "mounts and storage"
4)then "mount /data"
5)in cmd i tryed your command "adb pull /data/property/persist.sys.usb.config" but i says i'm unauthorized
i checked via command "adb devices" and it return a alphanumerica string plus "unauthorized"
i tryed then to
Reboot your phone into recovery mode.
Connect it to your computer.
Open the terminal and type:
cd ~/.android
adb push adbkey.pub /data/misc/adb/adb_keys
adb shell reboot
but it still says error : device unauthorizated . please check the confirmation dialog on your device

i tryed also with a different version of adb and now gives me after "adb devices" an "offline" response
NB: if i connect the phone (not in recovery mode) via usb i can copy files in and out (i can explore onlyfew folders) , maybe this could help.

Sorry but this could not help... Now only thing you can do is connect any USB mouse to your phone via otg cable (as it is not costly also), and you can also try USB gamepad. I also have used USB gamepad before when my touchscreen was not working.
Second thing you can do is download any android device manager for your PC like mobogenie or mobilego they directly install any app from play store to you android device, through USB.And I don't think they need USB debugging option to be enabled.

my problem is not installing an app (i could do it in recovery mode with a .zip) but enabling the USB debuggin
I have a otg cable but not the "Y" type ( the one with power source ) , also i don't know if OTG is supported by my kernel . I would like to install maybe another kernel which has OTG support and usb debuggin mode enable by default but i don't know what kind of rom i have D:

right now i just need a rom/kernel with USB debugging mode enabled by default

Bloatware Apps Removal via ADB

Hello Everyone,
I would like to learn how to remove bloatware Apps from my Android phone.
I have tried using "ADB commands" but for some reason my computer doesn't recognize/find my Android phone when I connect it to it.
Please help.
Thanks in advance

Download drivers for samsung and enabled adb developer option then type following "adb devices" press enter and should see serial number indicating phone connected via adb

Hello, and Thanks
I have done that exactly, but it still doesn't work.
And I can't figure out why is not working.
I have installed the Samsung driver, allowed the ADB function on my phone from "Developer Options" etc.

In addition to the advices by petiolarissean , check whether the driver works well, please.
In the 'Devices Manager' of your Windows, check the driver for your Android phone.
If this doesn't work yet, change an usb cable and then try again.

Only to have mentioned it:
So-called bloatware typically is housed in Android's locations /system and/or /system/priv--apps what only can get accessed by Android's root-user after successfully mounted as RW.

Question ADB TCPIP mode w/o cable

I've been looking around for a way to enable ADB TCPIP mode without cable, and I just couldn't find something that works without rooting the device first. The Tasker trick is waaay too complicated, and I couldn't make it work on my Pixel 7 Pro.
When root is available, things look simple: run "setprop persist.adb.tcp.port 5555" or modify /system/build.prop to include a line to that effect. Assume that I go to the trouble of rooting my phone, and make the requisite change in /system/build.prop, will I be able to un-root afterward while keeping the change I made intact?
Edit: here's a wild thought: maybe I can actually tinker with the official Android factory image, hence add the requisite line to /system/build.prop in vitro, as it were, repackage the whole thing as a modified image, and then flash it onto my (unrooted) phone. Will that work? Or does the flashing process check the checksum before flashing?

For one, my adb doesn't seem to know the "adb pair" command ("adb: unknown command pair"). Moreover, the IP address provided by the "Pair with device" menu is funny, along the lines of 100.xxx.xxx.xxx, hence it's not an usual 192.168.xxx.xxx. Finally, this doesn't really lend itself to scripting, as the pairing code changes all the time.

Are your tools up to date? What is the output of:
Code:
adb version

Update your tools, you should be on 33:

Android Debug Bridge version 1.0.41
Version 33.0.3-8952118

I have a script for that, I forgot to include it...
Edit: can't attach it for some reason, anyways, here's a link to my git: update_platform_tools

Thank you. Anyway, it may not be of much help, as this procedure needs to be repeated after each reboot, and is not scriptable. I, for one, am interested in writing a script. For now, it's easier for me to connect the phone via USB and run my script every time after reboot.
About the rooting/un-rooting questions I was asking in the OP, any opinions about those?

As for things you can do with root, I have nothing to offer, in fact, I am totally against it. It just causes unnecessary problems with the device.
However, you *may* be able to modify the stock rom with an Android ROM Kitchen, emphasis on the "may".

So what's would the point of OTA file signatures if anyone could modify the original ROM with dangerous changes?

It worked fine for me after killing adb ($ adb kill-server)

USB port please help

If a USB port is disabled on a device and I'm unable to adb into it, is there any file or method I can try to enable USB port? When I ADbB devices it reads unauthorized. If I try and ADB mount I get the ADB help screen.. please help

How did you find out that the USB port is disabled? With the command 'adb devices' what is the output? Do you get an alphanumeric output along with "unauthorised"? If so, it doesn't mean that the USB port is disabled. It means that the prompt on your device (when you use the command) asking whether to allow the adb connection has not been approved.
If you don't get the prompt, then search for a solution for that.

ADB for phone to phone? I don't understand the question. ADB will work if it is authorised on your device.
