How to manually update su and SuperSu file through ADB root shell?

I have an un-rooted device, with Android 5.0 system, and the core is ARM Coretex A53.
I happen to found "adb root" works, that means I can play as root through ADB shell.
I successfully deleted a trash apk, renowned "kingroot", from my system.
Then, I try to manually update su and SuperSu file, through the bellowing commands:
# mount -o rw,remount /system
# cp /sdcard/mrw/su /system/xbin/su
# cp /sdcard/mrw/su /system/bin/su
# pm install /sdcard/mrw/superuser.apk
(I'm using a 2.46 SuperSu version, which should be OK for Android 5.0 system)
But it fails. The SuperSu told me " su binary not installed".
My questions:
1. Is this a feasible way to update Su and SuperSu, and get root access?
2. There's a bunch of architect, I tried both "arm" and "arm64", but none of the su binary can work. Which architect shall I choose, when I'm running on a ARM Coretex A53 core? ( I know it is a 64bit core)
Thanks a lot, and Best Regards,
towenyu

Did you get this device secondhand? Also what device is it, since many have their own root method because of OEM crap.
That said, you only need su in one location, either /system/xbin/su or /system/bin/su (I typically see it in /system/xbin/su). I'm not sure what happens if it's in both, but it's just wasted space.
You can try these commands through adb root; since you already were able to get su onto your device, it may be just a matter of ownership and permissions:
Code:
# mount -o rw,remount /system
# chmod 755 /system/xbin/su
# chown root:root /system/xbin/su
# mount -o ro,remount /system
chown 755 sets the permissions to rwxr-xr-x (user gets read/write/execute, group/other gets read/execute). Execute is the important bit here, since otherwise the su binary can't do its job. After those commands, try SuperSU again and see if it works (you might need a reboot, because of how Android 5.0+ handles changes to /system) The last mount -o ro command just changes /system back to read-only, to prevent accidental changes to other parts.

Successfully rooted!
Not that simple, but basically follow the update-binary script already inside supersu package.
Only need to made slight modification due to my system won't support "unzip"

Now that you're successfully rooted, go install Busybox, that'll give you a lot of Linux commands Android doesn't have by default, including unzip.

Thanks for your advice! I will try it.
But don't there's already a Busybox in android system? I guess what I need to do is find somewhere a more powerful busybox binary -- or build it by my own, but that may be not so easy for me.

Android has some basic Linux commands support, but I don't think it has Busybox (if you have a custom ROM you may have some additional commands, but since you said unrooted I don't think it was installed.
This is one of the most popular installers for Busybox: https://play.google.com/store/apps/details?id=stericson.busybox
I've used it since I first rooted with Android 2.2 and haven't had any issues with it (save for lack of vim, since stock Android doesn't have the correct libraries for it)

rooting my htc m9 running marshmallow
Hi, I'm totally blind, and twrp isn't an option for me since it doesn't have a built in screen reader. I would like to install supersu to system, would some one kindly help me in telling me what files to put where. I think the m9 is arm64, but besides su and supersu.apk, I think there's installrecovery.ssh and some other files that have to go in, so please help some one

Hi guys ,
it is possible to run manualy via adb shell update-binary file from META-INF supersu folder for install it ? (means before unpacked folder supersu is copied to ex. /tmp)
I'm asking bcose no custom recovery and no root on my device yet.
Thx

Thank You - I will check and give feedback

Can I somehow just copy su and supersu files to phone (stock ROM) with full root shell to get root? Unfortunately bootloader is locked and only root shell is available.

Of course not. If it were that easy rooting would be a non-issue for devices with a locked bootloader.

I'm in a similar situation (/system/bin/su and /system/xbin/su "updated" from Supersu zip , root access from adb shell , rom built as userdebug) but I'm unable to launch the update-binary through adb to get the TV fully rooted..

How to use ?
Use adb shell or Terminal command for mount and modified system,... without su binary !!!
Example:
Code:
adb root
adb shell
mount -o remount,rw /system
rm -fR /system/app/*Knox*
...

tried this method and the phone hangs on boot. i was able to flash the kernel but nothing else.

Anybody else try this ?

Could you please assist in finding a stock image to unbrick our phones? Instructions would be appreciated too. Thanks!

Hold volume down plus power and home key. Get into download mode and flash stock Odin files located in the general section. I'll just wait till s6 gets marshmallow.

Anybody found some more progress with this in other locations ?

This doesn't work.

Still doesn't work.

already a thread on these files. this is not root and really shouldnt be flashed as they do nothing for our 920A s6. unless a dev can use these to get full root then these will not benifit anyone right now thats needs root for root apps or anything else really.

Worked for me. I have adb root but can't do much. I tried to perform a manual install of supersu, but no luck in getting it working fully.
From a directory that has the arm64 and common files from SuperSU zip flle I tried the following:
Code:
adb shell mount -o rw,remount /
adb shell mount -o rw,remount /system
adb shell mkdir /system/bin/.ext
adb shell chmod 0777 /system/bin/.ext
adb push arm64\su /system/bin/.ext/.su
adb shell chmod 06755 /system/bin/.ext/.su
adb push arm64\su /system/xbin/su
adb shell chmod 06755 /system/xbin/su
adb push arm64\su /system/xbin/daemonsu
adb shell chmod 06755 /system/xbin/daemonsu
adb shell mkdir /system/app/SuperSU
adb shell chmod 0755 /system/app/SuperSU
adb push common\superuser.apk /system/app/SuperSU/SuperSU.apk
adb shell chmod 0644 system/app/SuperSU/SuperSU.apk
adb shell adb shell SYSTEMLIB=/system/lib64
adb shell LD_LIBRARY_PATH=$SYSTEMLIB /system/xbin/su --install
adb shell /system/xbin/su --install
adb shell rm /system/bin/app_process
adb shell ln /system/xbin/daemonsu /system/bin/app_process
adb shell rm -r /data/dalvik-cache
adb reboot

i am a user of S6 active,does the thread work on mine?please~

I also tried to push the files to following place, supersu still cannot work properly. Couldn't figure out why.
/system/etc/init.d/99SuperSUDaemon
/system/etc/install-recovery.sh
/system/bin/install-recovery.sh
/system/xbin/supolicy
/system/lib64/libsupol.so

Can get it working on first boot. But retaining it is an issue. Still need more time. Anyone else who's good here can PM me and I'll provide my steps. Please only someone who's familiar with rooting on a technical level. ROM devs etc. Thanks

So what I have figured at this point is that SeLinux needs to be set to permissive from kernel cmdline and unfortunately without an unlocked BL or a Kernel that is flashable that already has Selinux set to permissive, I am stuck running this manually through adb shell each boot and the boot itself takes about 5 minutes before adb responds again. I can provide this method but its not 100% working obviously due to lacking the ability to run kernel cmdline. I am open to suggestions.

I've tried to manually root using this guide:
https://forum.xda-developers.com/showthread.php?t=2684210
with no joy superuser app detects the binary but no other apps can get root.
i can mount /system/ for write etc if anyone can point me in the correct direction etc maybe twrp or something.
Also any ideas what this might be for:
sys.whitelist.enable=true

if anyone interested i managed to get root from this script over ADB

works great i now have root!

Hi, I have a similar unit but having problems looking for ROM. Can you share sources or your ROM please?
Mine is a generic head unit model id T3 K2001M which I managed to root after x number of tries using kingroot apk
My issue now is that most settings are locked (not enabled). I think the manufacturer stripped some of the OS system files.
I tried using the Bonroad ROM for T3-P3 but it's saying not compatible.

Great. Thanks for the suggestion will try that out. I hope we can get some ROMs soon. Will let you know if I stumble on any.

Hi, how did you connect to the unit to run ADB commands? My unit only has full-size USB connectors so I would need a USB-A to USB-A cable. The only other thing I can think of is to connect an android phone to it and run adb from there somehow. I've installed a terminal app on the unit so could copy the files onto a usb stick or sdcard and run the commands directly on the unit....?

On the unit download adb over wi-fi from playstore make sure both laptop and unit are on same wi-fi network, look into adb over wi-fi.

thanks for the script, i managed to root mine
Do you use tasker on this device? I try to but my accessibility are always revoked, so i can't use application start event.
Also, if you launch music with another then the original music player, when you return to home menu, does it turn of the player?

because of you and your root method, I just find where I can stop the CT-0008 to stop an app when return to home screen
So, you just have to add your package name in the list:
/config/app/TaskWhiteList.xml

Hi yeah I did see that. Not tried it yet trying to figure out how to play Bluetooth music in background. Also not used tasker either

hey guys just read this, I also have a generic T3 K2001M, here's my question lets see if you can help me:
the device automatically runs radio app at start up (boot), this is the only thing I wanna change, I want it to run the music app instead. I surffed to all possible options and I haven't managed to do it. Do I need root for that? any idea how to do it? thanks a lot!

You've got to root it and make a profil wich start music player when radio start. I didn't find another way

Hi,
I tried to root CT008 as well, and I've got an error on the last line.
adb shell ln -s /system/etc/install-recovery.sh /system/bin/install-recovery.sh
Cannot install link already exists or something similar.
Now, when I start SuperSu, I've got an error that binaries are occupied. I can't uninstall supersu (no option to do so).
Kindly please give me your advice on this

reflash with original rom and try again
Original rom here (update.img)
is your sdcard keeping unmonut after sleep?

I guess you have trouble with wires. Is your unit for car unit. If it is car unit you have to check to red and yellow wires. Red one is must connect to acc + and yellow one must to connect to battery +
Or you must connect both of that two cable to battery +.

In My case, I have managed to start music player at start-up. I have to cross check the settings. Will let you know.
You could access the factory settings with code: 1617
Presently looking for a complete player which can play wma files too and I can associate it with the car launcher widget.

[Q] How to bypass ADB block (or how to reinstall ADB) on Android system?

I have a 65 inch XiaomiTV 3 (note, this is a different flavor of OS from MiBox), it works great until Xiaomi starts to push video ads everytime I turn on the TV. Xiaomi has disabled (likely completely removed ADB) from their system (mine is 1.12.10, any newer version would not be allow u to gain root access in anyway, unless you prove me wrong). Since there is no way to install a new recovery on XiaomiTV 3 (not that I know of, I should add), I tried the only tool that can root this system with an exploit, the 360 Root (http://root.360.cn/). Now this tool itself has some ads, so I will need to remove it later. But at least it allows me to use `su` in a terminal emulator.
Once I gain the root access on my device, I first tried to use ADB by running (and I need to add, XiaomiTV 3 does not have USB debugging port) a terminal emulator (I use Android Terminal Emulator):
Code:
su
stop adbd
setprop service.adb.tcp.port 5555
start adbd
Then I try to connect to my XiaomiTV 3 (its ip is 192.168.123.123) by:
Code:
adb connect 192.168.123.123
It connects, meaning ADB is not removed completely. However if I type `adb devices` it shows 192.168.123.123 is offline.
I then upgraded my Android platform tools and adb by:
Code:
android update sdk no-ui
android update adb
Restart the adb server:
Code:
adb kill-server
adb connect 192.168.123.123
Here it still shows offline, so I restarted both the XiaomiTV 3 and my laptop, and regain root (I will lose root everytime I reboot XiaomiTV 3), did the above all over again. No luck. Then I thought to copy my `~/.android/adbkey.pub` to a usb drive, and then plug it in to XiaomiTV 3, then use a terminal emulator to:
Code:
su
mv /mnt/usb/sdcard/adbkey.pub /data/misc/adb/adb_keys
Then
Code:
stop adbd
setprop service.adb.tcp.port 5555
start adbd
Still, after I
Code:
adb kill-server
adb connect 192.168.123.123
the device is still offline.
Then I tried another approach to get get SuperSU to the system by first copying supersu to a USB drive and then copy it to `/data/superuser` in XiaomiTV 3.
Then I did:
Code:
su
mount -o rw,remount /system
mkdir /system/bin/.ext
chmod 777 /system/bin/.ext
chown root /system/bin/.ext
cp /data/superuser/su /system/bin/.ext/.su
chmod 6755 /system/bin/.ext/.su
chown root /system/bin/.ext/.su
cp /data/superuser/su /system/xbin/su
chmod 755 /system/xbin/su
chown root /system/xbin/su
cp /data/superuser/su /system/xbin/daemonsu
chmod 755 /system/xbin/daemonsu
chown root /system/xbin/daemonsu
cp /data/superuser/supolicy /system/xbin/supolicy
chmod 755 /system/xbin/supolicy
cp /data/superuser/libsupol.so /system/lib/libsupol.so
chmod 644 /system/lib/libsupol.so
mkdir /system/etc/init.d
chmod 644 /system/etc/init.d
cp /data/superuser/99SuperSUDaemon /system/etc/init.d/99SuperSUDaemon
chmod 744 /system/etc/init.d/99SuperSUDaemon
busybox_xm touch /system/etc/.installed_su_daemon
echo 1 >> /system/etc/.installed_su_daemon
chmod 644 /system/etc/.installed_su_daemon
mkdir /system/app/SuperSU
chmod 755 /system/app/SuperSU
cp /data/superuser/SuperSU.apk /system/app/SuperSU/SuperSU.apk
chmod 644 /system/app/SuperSU/SuperSU.apk
cp /data/superuser/install-recovery.sh /system/etc/install-recovery.sh
chmod 755 /system/etc/install-recovery.sh
ln -s /system/etc/install-recovery.sh /system/bin/install-recovery.sh
Then I reboot, apparently, the system overwrites the `/system/xbin/su` (either by 360 root or Xiaomi's OS). So I redid everything above, without reboot. Sadly, SuperSU still asks me to upgrade/update my binary file.
So this is when I stopped knowing what to do next. Any ideas?

Issue with SuperSU on AndroidThings 1.0

I tried to perform a manual installation of SuperSU (2.82 SR5) on my Raspberry Pi running the developer version of AndroidThings 1.0.4, which is based on Android 8.1.0 / API 27. Rather than flashing the zip in recovery, as I'm not sure where to start with that on the Things platform, I manually pushed files and set file permissions and contexts via adb shell. My guide for this was the summary at the top of the script at SuperSU/META-INF/com/google/android/update-binary.
The new su binary appears to work for the most part. I can execute su and read/write with the interactive shell. However, when I attempt to execute the same operations as a command through su (ie: su -c mkdir /system/testdirectory), it responds saying its a read-only filesystem. The filesystem has been remounted with adb remount. I'm unable to perform the remount with the mount command, as /system is not listed in /proc/filesystems. From my understanding, this is due to some recent security model changes in Android. That being said, after the adb remount, all other normal interactions with the filesystem seem to work without issue. I have verified that selinux is in permissive mode.
I don't have busybox installed. These efforts are to allow for installation of busybox for other projects.
Does anybody know whats causing the commands proxied through su to not work correctly?
Here are the commands I used to perform my manual installation.
Code:
cd ~/Downloads/SuperSU-2.82-SR5
adb connect [IP_ADDRESS]:5555
adb root
adb remount
adb push common/install-recovery.sh /system/etc/install-recovery.sh
adb shell chmod 0755 /system/etc/install-recovery.sh
adb shell chcon u:object_r:toolbox_exec:s0 /system/etc/install-recovery.sh
adb shell ln -s /system/etc/install-recovery.sh /system/bin/install-recovery.sh
adb shell chcon -h u:object_r:toolbox_exec:s0 /system/bin/install-recovery.sh
cd armv7
# adding as `su_next` to prevent any issues before dropping it in
adb push su /system/xbin/su_next
adb shell chmod 0755 /system/xbin/su_next
adb shell chcon u:object_r:system_file:s0 /system/xbin/su_next
adb push su /system/xbin/daemonsu
adb shell chmod 0755 /system/xbin/daemonsu
adb shell chcon u:object_r:system_file:s0 /system/xbin/daemonsu
adb push supolicy /system/xbin/supolicy
adb shell chmod 0755 /system/xbin/supolicy
adb shell chcon u:object_r:system_file:s0 /system/xbin/supolicy
adb push libsupol.so /system/lib/libsupol.so
adb shell chmod 0644 /system/lib/libsupol.so
adb shell chcon u:object_r:system_file:s0 /system/lib/libsupol.so
adb shell cp /system/bin/app_process32 /system/bin/app_process32_original
adb shell cp /system/bin/app_process32 /system/bin/app_process_init
adb shell rm /system/bin/app_process
adb shell ln -s /system/xbin/daemonsu /system/bin/app_process
adb shell rm /system/bin/app_process32
adb shell ln -s /system/xbin/daemonsu /system/bin/app_process32
adb shell chmod 0755 /system/bin/app_process
adb shell chmod 0755 /system/bin/app_process32
adb shell chcon u:object_r:system_file:s0 /system/bin/app_process
adb shell chcon u:object_r:zygote_exec:s0 /system/bin/app_process32
# Swapping new su binary in
adb shell cp /system/xbin/su /system/xbin/su_original
adb shell rm /system/xbin/su
adb shell mv /system/xbin/su_next /system/xbin/su
adb shell /system/xbin/su --install
adb reboot

I need to correct myself: the new su binary can only read with privileges. It cannot write at all. I am only able to write either as the adb root shell, or with the stock su binary. I noticed that the device's adbd process relaunches with its own privileged context passed to it when adb remount is run. (adbd --root_seclabel=u:r:su:s0)
If I've run adb root and adb remount, adb shell, and then enter the su binary, I lose the ability to write to the remounted filesystem. So it appears that there is something wrong with the new su binary and its related files.
Anyway, this isn't critical to my project, so I'm abandoning my efforts for now. If anyone has any ideas on what is wrong here, I'd love to hear them and give this another shot!
