[Q] Can I use a Nexus 7 to root a cellphone?

Can I use a Nexus 7 to root a cellphone?
Is there a way to put ADB on the Nexus 7 and use a MicroUSB to MicroUSB cable to root a cellphone?

Night be possible, real question is, is it smart to do so? Stability wise I wouldn't do it, but that's me

That's a good question I was wondering the same thing. I have a full keyboard with my nexus 7.I don't know if that would make a difference or not. Good luck!!!

adb shell and Terminal Emulator are not the same thing. One is an shell environment (adb shell) and the other is a tool to access that environment (Terminal Emulator).
adb shell is native to the phone and allows for Linux shell access. Terminal emulator will allow you to run adb shell ON the phone directly to access that shell environment.
Secondly, yes you are correct, in that you can use the Command Prompt (CMD) to access adb shell. Also, your phone must be in debugging mode as you stated.
To get a list of commands -- you type: adb, while in the androidsdk\tools folder and it'll display the default set of commands available to you.

From this post that I found in a random, non-related thread, it sounds like ADB is already part of the Android OS. So it's possible that all I need to do is install a Terminal Emulator on a tablet, connect the tablet to an Android phone via cable and run an "adb devices" to see if it's connecting.
I'll try to do this sometime this week and see if it works.

Just tried with OTG cable in Nexus 7 with MicroUSB cable in my GSII and I couldn't get it to work. It didn't give a notification on the phone about Debugging being connected but it did start charging the phone.

S-OFF a HTC One M8 on a MacBook

Hey Guys, i have a very big problem.
i cannot S-OFF and Root my M8 on my Mac
ADB are installed
Fastboot for Mac also.
USB-Ddebbuging is enabled.
where is the problem, it cant find my Device.

Is USB debugging enabled?
Also it should come up a little notification on the M8 asking for permission for the computer to use it... Did you accept that?

Thats strange...
Try:
Type adb kill-server
Type adb start-server
Type adb devices
I always set the superuser to accept all requests while doing ADB or fastboot, its just easier lol.
In my case I installed htc sync, then connected the one m8 and then dragged a couple of files, then uninstalled the htc sync and tried again... Just for drivers sake... Even on my Mac.

No doesnt work

ADB working only via WiFi, with USB after su with command

Hello everyone
Recently (today exactlly) I tried restore/repair IMEI with method shown in this video (https://www.youtube.com/watch?v=y2lHFy7AciE).
IMEI is visible but after restarting D855 adb via USB no longer works. It's no longer visible in Devices Manager and of course I can't connect PC with phone anymore with cable.
ADB via WiFi works very well.
I found a way to make it work with cable after entering commands via WiFi. The commands I'm using to make it work:
Code:
adb connect #my_d855_ipadress
adb shell
su
setprop sys.usb.config diag,adb
The question is, what I have to modify in /system to make it work always without juggling commands with adb over wifi first.
If this question was asked, please let me know (I already used search).

I'm late to this thread, but luckily, as of Android 11 and up, adb works over wi-fi (without USB) on non-rooted Android phones via Developer options Wireless debugging switches.

Your Firestick is rooted? You can enable USB tethering via ADB or using Termux on Firestick
Code:
//Enable
adb shell su -c service call connectivity 30 i32 1
//Disable
adb shell su -c service call connectivity 30 i32 0
I found the link how to enable/disable USB tethering:

How to properly close adb wifi connections.

Hi,
I noticed that the adb wifi daemon gets blocked by the first app that connects to it and another app can not connect to it until I toggle ADB Wifi manualy under fire tv 4k's device settings.
What is programaticaly the correct way of disconnecting from the adb daemon and free it up for other apps to connect?
adb disconnect doesn't seem to work.

"adb disconnect" will not work for you because you are not using adb you are using its shell.
Type "exit" and your shell connection will die freeing it for other apps.

It doesn't work on Fire TV 4K. I have tried several tools, local ADB shell, remote adb shell, Tasker and "exit" command does not properly disconnect the adb session. I have to manually toggle adb access to free the adb shell for another application. It does not matter what application first starts the adb connection exit does not free the session. Only toggling the adb manually in Fire TV Device settings frees it up. Otherwise the adb session will remain active only for the tool that first established a adb session.
Its a huge problem, if the adb shell can only be used by one application and gets blocked by it all the time.
Why is exit not working on fire TV 4k?

So you are saying its a problem with Firestick 4k aka mantis. It is not, i know shell connection does not free itself and it has to be implemented in the app.
Try using any one of my app, Launcher Manager, Debloat Toolbox, Update Blocker (make sure you use the latest) they all leave the shell after getting the work done, and you can still use other apps. I think you might also have used "Mouse Toggle", which also leaves the shell after starting its services. So its not the devices problem, its how the shell is handled by the app.
