[HOW-TO] [ANDROID TERMINAL EMULATOR] Switch to root user automatically - Android General

Hey there folks!
I found something out recently that is pretty useful.
Many of you surely use the Terminal Emulator.
Most actions require root privilegies and you always have to type in 'su' to aquire them.
It is possible to run it as root automatically.
Just follow this easy steps:
1. In the app, press the menu button and click on preferences.
2. Scroll down to the command line option and click on it.
3. Now remove the old line and enter this:
Code:
/system/xbin/su
If you prefer bash over the standard sh, add this line:
Code:
-s /system/xbin/bash
That's it, you now have a rooted terminal without any interaction.
I hope this is useful to you and have a nice day!

By the way, this depends not on the device. The su binary just has to exist in the described location, that's all.

adb install in terminal emulator?

Some of you are familiar with the adb install command.
Is there an equivalent of it in the terminal emulator?
Hi,
Adb is used from the computer and terminal emulator is used from the phone.
What are you trying to do?
I'm trying to install an app without using astro.
your best choise would be
cd to the location of the apk file and use
adb install appname.apk
or adb install C:\folder\appname.apk
think thats the correct way im not sure how you can install it in the terminal i knwowho to remove it.. but not install :/
Install .apk via Terminal EMulator
1) Place the .apk on the root of your SD card (for simplicity)
2) Type "su"
3) cd into the destination of your .apk (in this case it will be cd /sdcard)
4) Use "install "name of .apk" /"destination"/"name of .apk"
su
cd /sdcard
install com.makemobile.coursepro.apk /system/app/com.makemobile.coursepro.apk
further example:
install "space" com.makemobile.coursepro.apk "space" /system/app/com.makemobile.coursepro.apk
This will install the app on your phone using the Terminal Emulator. The destination location can change as well.

On the flip side, could you uninstall from the ext2 partition this way?
install on/from ext2
not sure...I'll looks into this. I had my apps and data on my sd however, it seemed a little buggy and inconsistant. It may have been due to using original G1 1gb class 2 card.
-let me know if you find out first.

cd is a command, meaning "change directory". Which is used to move your location on the system.

cd is a *nix command , it is short for 'change directory' and it... changes directory

it depends on what the app is
your best bet would be to get an app called 'Astro file manager' from the market
Its quite easy, so I won't go into further detail
Which to be honest is a fair trade

Some people have mentioned the `install' command from BusyBox, but this won't quite do what you probably want. To invoke the full Android package installation experience--the complete equivalent of `adb install'--you're looking for `pm install'. It takes the same arguments that `adb install' does, checks signatures, creates the appropriate user accounts, etc. so the package is installed the Android way. You can also use `pm uninstall' to remove a package (and as with `adb install', the "-k" option keeps its data around).
The `am' and `pm' commands are both underdocumented, but can be terribly useful. `am' can issue arbitrary Intents, including some Extra values. `pm' has other features not mentioned here, but which are shown in the help text.

'pm install' often fails with [INSTALL_FAILED_INSUFFICIENT_STORAGE]
which used to frustrate me no end ..
simple shell script
Code:
am start -a android.intent.action.VIEW -t application/vnd.android.package-archive -d file://$1
just pass the full path e.g
sh /sdcard/installapk.sh /sdcard/theapp.apk
and it pops up the Android Package installer

Interesting. I wonder if that's related to A2SD or a particular implementation, and pm getting confused as a result? Still, I like the idea of sending the VIEW intent to bring up the package installer. Good snippet.
I just cp the files to /system/sd/app/
from Windows Command prompt, and after switching to the folder containing the .apk file, type:
adb install filename.apk
if it is a reinstall:
adb install -r filename.apk
you could also push the file to the app folder. I use this method to push system apk:
adb remount <<<< you have to remount since you're going to mess with a sys folder
adb push filename.apk /system/app
seriously useful thread... especially after for some weird reason certain apps fail to install using the default Android installer. *cough* Radiant *cough*
Thanks for the help guys. Btw install command doesn't work. To clear things out for some clueless person like I am :
1. Open Terminal Emulator
2. Type -
su
cd /dir
pm install appname.apk
3. Done!
Example -
su
cd /sdcard
pm install AstroFileManager.apk
Hope that can help!

{Howto}Downgrrade form rooted 1.47.651.1

Ok... If your wimax isn't working and you want to downgrade to try to get it working this is how to do it...
1st get all of the files like you want to do Toast's Part-2. link: http://forum.xda-developers.com/showthread.php?t=701835
Then do this part:
STEP 2~FLASHING MTD PARTITION TO ENABLE DOWNGRADE:
- download all files posted above
- unzip the flash_image.zip and the mtd-eng.zip
- put the flash_image and mtd-eng.img on the root of your sdcard
- go into shell on ur pc and do:
adb shell
cat /sdcard/flash_image > /data/flash_image
chmod 755 /data/flash_image
/data/flash_image misc /sdcard/mtd-eng.img
- this should only take a second or two
- now put the PC36IMG.zip on the root of your sdcard
- power off the phone
STEP 3~FLASHING ENG BUILD:
- hold volume down + power to boot into hboot
- it should now find and verify the PC36IMG.zip on the root of your sdcard. itll show a blue status bar on the top right of the screen.
- after a minute or so it will ask u if u wanna flash SAY YES
- affter it flashes the PC36IMG.zip it will ask if you wanna reboot. SAY YES
After if finally boots you should see HTC quietly brilliant which hangs forever but it should eventually get past it. Once it does you will have the oldest everything. This is a beta build and has a bunch of tools but just do an upgrade to root like you normally would. I would suggest going to .6 then upgrading to the latest 47 from there.
Hope that this helps someone.
P.S. is anyone willing to dump all of the tools that are included in this rom. It might be helpful for the other devs.
Thats the hard way... but yeah it'l work.
Why is everyone so hype on adb everything...?
Tell me the easy way. I would love to do it instead.

It's just easier to copy and paste stuff, even typing on a real keyboard. It's a pain in the ass doing it via terminal emulator with the lack of a physical keyboard on our Evo's.

I used the toast method. And if i'm not mistaken I should flash roms w/o the 1.47.651.1 OTA update after downgrading right?
Nope, I try this method and it is not working. Some how the new OTA encrypted a code that any lower version will not over write it.
You don't have root access to even copy/paste or push the files to /data. I tried this and got a permission denied error message.
How do you input adb shell into Vista, I clicked "start", "run" and type "cmd" it bring up C:\users\XXXXX\ cd c:\android hit "enter"
then I type
c:\android>adb remount
Access is denied
Please advise what I did wrong. thanks
It worked for me... you have to make sure that when you enter the su command in adb to look at your phone. There should be a super user permission box that pops up. Accept it and youll be able to adb. It went fine for me after that.

1) Put your phone on USB Debug
2) On your Phone make sure the Ninja(SuperUserPermission) is set to prompt you when you have a request.
3) go to your PC and type in adb shell
4) type in SU
5) Once do you that you will see a prompt from the Ninja asking for a request. Allow for it. And it will remember from that point forward.
6) Look at your cmd prompt screen for a # - if you have it you have full access.
Then so what commands you have been given to do.
It can also be done from the Android Terminal Emulator but some might not like working with a smaller screen I like it myself. Makes me feel geeky

This would only work if after the messup your still has root access. Some people have root and the "SU" will work but for the people w/o root will get access denied.
also
From above (I hate quoting) have you tried going to your tools folder inside your android folder and from there try your adb commands?
If you applied the OTA sent from Sprint, you lost root access. There will be no Ninja in the programs folder, because it was a new rom that the was flashed with the OTA. Root access has been closed for those that downloaded the update. If you try and type su, you will get permission denied.
Those of you that still have the root and superuser rights, DON'T DOWNLOAD THE OTA!! You are in a better position then the rest of us. I wanted the good battery life, so that's why I did it.

Can be closed now.

Just curious. I tried to root a Gingerbread emulator with the new Gingerbreak method, but that didn't work.
Typed by Z using the Gingerbread keyboard.
It's rooted by default. What do you want to do?
No it's not, try su-ing in a console.

Code:
$ adb devices

$ adb shell
# <-- '#' indicates that I'm root.
# umount /cache <-- only root can do that
# su <-- su works too

Do you use "adb shell" or some terminal emulator app?
yes the emulator is already rooted, but it cannot run root-required app, like root explorer.

Reboot from terminal emulator

I'm trying to reboot from terminal emulator. What I type is:
Code:
su
reboot
or
Code:
su
reboot -p
but it always returns
Code:
Not permited
.
Note that I get the same "Not permited" both with gaining and not gaining su access before executing the reboot command.
This is a known problem (see here for example) but I haven't been able to find a solution.
Of course, root is working fine on my rom so that's not the problem.
Anyone using reboot from terminal emulator?
Thanks

reboot the phone for me. I'm on latest Carbon rom.
You could try
Code:
su
shutdown -r now
but that will probably have the same result...
Is there a specific reason you want to be able to reboot from terminal? If you are looking for quicker access to recovery or bootloader and are using an AOSP rom you could enable the advanced reboot menu in developer options to get those options from the power menu. Hope this helps.

I'm on stock rom and I suspect that's the source of the problem: infact in the thread I linked above the user is on a stock HTC One.
I'd like to do it from terminal so that I can create a reboot event on Tasker/Llama.

Question How to do run root as Pixel 6A?

adb root
I have already tried the following command, but it says:
adbd cannot run as root in production builds

Uh.. What are you trying to do?
Are you trying to emulate a Pixel 6a on your computer, or do you want to have root privileges on your device?
I want to have write permission on /system/bin and /system/xbin, this is for the purpose of me importing nano into the devices. My main goal is to have a bashrc alias and and make it easy for me to edit files in the system.

You'll have to look into rooting then. I suggest you use Magisk. There are many guides on xda (specifically for this device too).
Even magisk won't overcome that error, because at the end of the day, it is a production build.
But that doesn't mean you can't use root! You just can't call "adb root".
Code:
adb shell
$ su
# <-- do stuff as root
# exit
$

Just to be clear, even if you have root, you can't easily write to the system partition. The system partition is mounted as read-only and to get around that you'd need several steps like a modified super partition, and potentially have verity/verification disabled.
Your best bet you be to use Magisk, and either use the Magisk mirror partitions to add nano, or use the Magisk nano module (https://github.com/Magisk-Modules-Repo/nano-ndk)

You can use Termux, or any other terminal emulator, type 'su', allow superuser privileges, and do stuff as root.

You never really mentioned where you suggest them use that bit of code you provided, nor have you suggested they use a terminal emulator (where they can obtain root privileges), but alright.

Terminal emulator application is irrelevant. OP was asking about ADB specifically.
hope you are aware that if you modify /system you can't ota update anymore

You CAN...but this can only be done in engineering and debug builds.
adb root restarts adbd with root permissions.
There is a way around this; use an elevated shell to write ro.debuggable=1 to /system/build.prop, /system/default.prop, or /data/local.prop
If you want adb shell to automatically start with root, add ro.secure=0
