ROOT BlackPhone 2 (BP2) with Sudo SU - Android Q&A, Help & Troubleshooting

Hello community,
I'm new in the forum, It's 2 days I'm fighting with this problem: I want to root my BlackPhone 2 using TWRP and SuperSU (I think that this is the only method that works with BP2, since KingoRoot and others are patched for security)
I flashed the recovery TWRP, then I tried the following SuperSU versions:
SR3-SuperSU-v2.79-2017...zip
BETA-SuperSU-v2.74-2.zip
SuperSU-v2.79-2016...zip
UPDATE-SuperSU-v2.79-2016...zip
None of them works, in TWRP all goes OK, no errors and no warnings, but then when I open SuperSU apk it says "There is no SU binary installed... ...If you just upgraded to Android 5.0".
This is really crazy because I'm running on Android 6.0.1 (Silent OS 3.0.7) and using Total Commander I can see /su directory.
Using a root checker app it says that my device is not rooted, but the SU binary is present and also the busybox one.
The Silent Circle's Security Center in their "Privacy Meter" app warns me "Security alert, active root access detected! ...."
For install TWRP I had to switch these things on in Developer Options: "OEM unlocking", "USB debugging", then I enabled installs from unknown sources by ADB and SD card.
Any help will be great, Thanks guys
EDIT: sorry for the Thread title, I can't modify it, it should be SuperSU not sudo su (too much linux)

But did you try sudo su? Install a terminal emulator and cd to the xbin directory. FYI, the SU directory is there by default afaik.

Oh I didn't knew that the /su dir was there by default sorry. I downloaded the terminal emulator and "sudo" is not a valid command, when I type "su" it says nothing, and "which su" tells "/su/bin/su", but it does nothing apparently.
If it's not rooted at all how can Silent OS say "root access active detected"?
I just installed SuperSU zip via TWRP, there are other things to do in order to maintain root privileges?
PS: another RootChecker app detects that busybox is installed in /system/xbin/busybox with version 1.13.3, I don't know how that happened, busybox is installed by SuperSU?

Unfortunately they are in the same situation. But I admit that I did not install the TWRP permanently due to a possible bootloop phone. Has anyone found a solution to the root?

i have same problem i want unlock bootloader .............need help plz!!!

After you flashed the su zip, did you get the superuser app?

Qualcomm mdp tablet APQ8064 root

I recently won this developer tablet and I can't seem to get on-device root access. It came with su binaries installed. (very old ones but I updated it) It also has an unsecured kernel because ADB always runs as root. However I installed superuser and it can't get root access and when other apps attempt root access something seems to be denying access before the superuser prompt is even able to come up. Just curious if anyone has any ideas??

This may seem like a stupid suggestion but I suppose you could try uninstalling the superuser app and use Chainfire's Super SU app to see if that might make any difference.
Tried that too lol. I was even able to go into old su app and toggle permission for super su to allowed and it still said fail when it tried to update binary. Thanks for the suggestion though. It seems to me the problem is that the chown and chmod commands are not sticking on the su binary. They appear to work but the actual ownership and permissions of the file don't change. Even when I do adb remount first.
I figured it out. For some reason I had to put the su binary in /system/bin instead of xbin. Which is strange because all my other device it went in xbin. Also the reason the chmod and chown commands were not working properly is because I forgot to do adb remount. (duh!) In case anyone is wondering this thing is a beast. I just wish I could figure out a way to get my Gameloft games to work. I (mainly modern combat 3 and nova3)

One way to get your games to work would be try side loading the Modern Combat 3 and Nova 3 APK's onto the device and installing them manually that way. Another way if that doesn't work is you could try modifying your build.prop and changing your product id to match the galaxy nexus that way the play store will think your on a galaxy nexus and it should say that the games are compatible then.

I know this is an older post but I'm at the same point where I can't figure out how to allow superuser access. I'm using the 8064 for research and I need the root access but can't seem to figure out how to update the SU. Any tips?

Do you have the Superuser.apk app installed along with the SU binary in the correct place /system/bin as mentioned by JBO1018? If you already had working root access before on the device and just need to update the SU binary you can open the Superuser app, then go under the info tab and tap on the SU binary version number this should then check for updates and then ask you if you want to install any found updates.

I have both the Superuser.apk and SU binary in the right place. Each time I open up an app that needs root access a toast message pops saying that the app has been denied Superuser permissions. I tried restarting both apps but its not working.

Try going into the Superuser app and under settings and then security the default behavior is set to prompt not deny.

Losing root access after jelly bean update

hey guys i need some help plz!!!
i had rooted my asus prime.......and my bootloader was still locked, after i rooted my device i also had rootkeeper to protect it incase i update.....to make a long story short, i was so anxious when jelly bean was released i wasnt thinking so i proceeded without temp unroot first before i did the update......so after everything completed i went to restore my root access and it was gone..........was so pissed off, so now from every research i did it says that there is no current root options for the prime jelly bean, anybody knows how to get it back or a way to root again.....im willing to downgrade if i can to get back my root access. please help!!!
You can't downgrade without using the ASUS unlocker tool. Yeah, I know... shocked me too....
There isnt a working root method working as of yet if you are certain you have lost root access.
Some people report having partial root and even having some apps that still retained root. If none of that applies to you then your screwed with the rest of us.

Hmmm I will have to try in ADB and see what happens.
If your prompt changes to # in ADB then that means you should have root access. With that you can restore full root properly to your device. You may be one of the lucky ones that just needs to uninstall and reinstall Superuser.

Well it did give me hope when I saw that but I can't get past stage 11 in this guide . I just cannot get ADB to mount /system as RW . Also entering su in Terminal Emulator gets "permission denied" and Superuser itself "fails" at updating binary.

What is the error when you issue the remount command? if I type remount I get: "remount: not found"
There is also an executeable that came with one of the 10000 root packages I have tried called fsrw. Pushing it to /data/local/tmp with ADB then running it via the adb shell out of that path should try to perform the remount.
If you are getting "operation denied" then you don't really have root =/

hi, to all those other rookies, i did a bit of reading and finally decided to update to JB from stock ICS .28 which was unlocked and rooted.
As i expected i lost root and have just manged to get it back, i first installed twrp for JB using fastboot method.

then after trying [ROOT][TOOL]Debugfs automated root [09/18/2012] and SparkyRoot Apk having read this can possible restore root although not in my case, for me i uninstalled super user and re-flashed via twrp,
(version Superuser-3.2-arm-signed.zip from thread http://forum.xda-developers.com/showthread.php?t=1911024)
Then when i rebooted i noticed luckypatcher app requested SU and root access was now working

Well.. I believe that everyone who'd not consider unlocking their tablets before the JB update would not unlock after losing root just because of the warranty, probably not because they don't know how but because about half of the forumers don't think it's worth the risk considering the hardware instabilities like the green camera module, light bleed etc.
And since you've already flashed a custom recovery you've unlocked more than just root, why not try a custom ROM based on stock JB?

How to Remove/Replace Kingroot (KingUser) with SuperSu

If you was one of those who root their devices by using KingRoot App and would like to remove kinguser and related files, you can replace it with the well known SuperSU.
Here's a small script to remove Chinese kingruser, all related files and folders, and install SuperSU.
This script will do all the work for you without using PC, just by terminal, first of all, thanks to chainfire for his SuperSU files.
Before starting :
Download and install Terminal emulator appTerminal emulator app
https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en
Download and unzip "Replace_Kingroot_With_SuperSU.zip
http://tiny.cc/fo78zx
Steps :
Send the extracted folder "mrw" to the internal storage of your device and make sure that this folder contains 4 files
Open Terminal emulator and type :
"Su" (without "")
Allow root permission
Type :
" sh /sdcard/mrw/root.sh" (without "" , notice there's space between sh /sdcard.)
It might display some error, but wait for 30-40 seconds and at the end it will launch supersu or open supersu manually.
Update su binary normal, then reboot.
Done !
I ran the script and it went thru to installing Super Su but I lost root and couldn't update binaries. I redownloaded King Root and opened it and I instantly had root back. Are there other files that King Root has installed that don't allow this script to work. If you have any insight it wouldbe appreciated. I know I am on a different phone but script seems to work up to a point. ZTE Z820 Android 5.1 Thanks
I can confirm this method works on Lenovo Vibe X2 running Android 5.0. New Kingroot 4.5, the one with crown icon, successfully replaced by SuperSU while root status remain intact. A process crashed upon Kingroot removal, however restart seemed to get rid of the problem.

May I ask did you have busybox already downloaded and installed? I see that the zip contains busybox as one of the actions of the script. Maybe that's why it didn't work for me?? Also I have Kingroot 4.9.2 and I'm thinking that is the main reason the script fails for me.

I had KingRoot v.4.85, on a KitKat 4.4.
The script didn't work, so I plug the phone and connected to the computer, opened a console, executed the adb shell command and start to give each of the script commands manually one by one.
The failure was at pm uninstall com.kingroot.kinguser (com.kingroot.RushRoot wasn't installed anyway).
The packet manager wasn't able to uninstall Kingroot. I had to uninstall manually using the phone
Code:
H:\Development\adt-bundle-windows-x86-20140702\sdk\platform-tools>adb shell
[email protected]_z10:/ $ su
[email protected]_z10:/ # mount -o rw,remount /system

I modified the script in this way:
After
Code:
pm uninstall com.kingroot.kinguser
I've added
Code:
am start -a android.intent.action.MAIN -n com.buak.Link2SD/.Link2SD
echo "Press any key to continue"
read typedkeys
The first of the three added rows launches Link2SD app (that I've installed on my phone since I rooted it); the last line pause the script execution.
I used Link2SD to uninstall Kingroot.
Anyway I have to say that, even though the installation of SuperSU seems completed without errors, the apps that asks for root permissions didn't receive the answer from SuperSU and they aren't granted root permission, so... it still doesn't work.
it did not work, superSU can not update binary and can not uninstall the other root app (kingroot)
guys,I am telling you a working method which worked for me..
but you are going to need some version specific apps for first time..
things you need...
1. clean MICROMAX a311
2. kingoroot KingRootSetup_v3.2.0.1129 (i can upload it if you want)
3. Supersume.apk {MUST BE VERSION 6.4} (application used to change from kingroot to supersu)
note -- Pay attention to versions,messing with them will not allow you to achieve target.
steps..
1. install kingrootsetup on pc(must have internet connection to work)
2. connect ur phone with ADB enabled from developers option
3. root ur phone by following on screen instructions...
4. after rooting,install supersume on phone
5.open the app,click on big blue button and wait...
done,replaced kingroot with supersu..

Just used this solution on a Vodafone Tab speed 6 (VF-1397).
Seemed to work fine but after updating superSU and rebooting the Tablet, screen went black when boot reached unlock screen and couldn't see or do anything except using the power button options.
After some reboots (lost count, ~5/6, and failed atemps to enter recovery), (and the removal of the sim card) the tablet finaly started to optimize all my apps as if the dalvik cache had been wiped.
Afterwards screen went black again and couldn't do anything again.
After some time was finaly able to enter recovery and i'am now trying to format everything.

Sorry to hear that...
can you tell how you were UPDATING supersu ??
i also updated from 2.4.5 to 2.6.5 without any problems...
were you using genuine zip of supersu meant for your device ??
or just regular zip ??
don't you have backup of your tab....you were rooted..
1st thing you were to do was to make a full backup...why didn't you did that ??
Script didn't work for me, tons of errors because the path wasn't right. Fixed it to have exactly the same but still plenty of errors and SU binary would not update.
That supersume.apk thing though... MAGIC!!
Thanks heaps!!!
Device reboots
Any idea why the device reboots when I press enter at the last command? I did everything correctly, step by step like you describe it but instead of replacing the KingRoot with SuperSu the device reboots and the KingRoot is still there.
The device is Sony Xperia SP (C5303)
Any help would be great cause I used the exact same method some time ago in my tablet (Lenovo A8) and it worked perfectly. But not in the Xperia and I don't know if I should fully unroot it and try a different method or what.

How to use sudo on Termux?

I have Termux and SuperSU installed on an android 8 old console, I am able to use su in terminal, when su command is executed, SU manager pops a window for permission, if I accept, terminal user goes into su. I installed tsu package, and when I try to run any command with sudo <command>, this error shows:
Code:
/data/data/com.termux/files/usr/bin/sudo: line 304: /sbin/su: No such file or directory
No superuser binary detected.
Are you rooted?
I noticed the su binary file is under the termux app location, /data/data/com.termux/files/usr/bin/su. And I checked the sudo script under /data/data/com.termux/files/usr/bin/sudo, all su related path reference are pointing to /sbin/su, knowing that I can try to modify the script to point to the su binary under termux path, or try to make /sbin/ writable and copy su file there.
But this way seems very sketchy, I haven't try those yet, just want to know is this the right way to deal with this problem?
Here are some extra info, in case they are relevant.
1. The device is a Xiaomi MI 5, gemini, running an official MIUI rom dev ver, bootloader unlocked, rooted before. But this issue seems more of general root and app problem so I posted here...
2. I flashed a Floppy kernel for Oreo, according to author's post, root is expected to be deleted, user should install root after kernel flashed, that is what I did.
3. After 2, adb root stops to work, not giving any error, but su won't be activated when adb shell is opened, but I am able to run su in the shell, permission window will pop on phone, after granted, it's su in PC terminal. This su is under /su/bin/su
4. Usually Miui has it's own security center where I can manage root permission, but after 2, it just shows bootloader is not unlocked, and apparently it shows it's unlocked when I try to unlock it again in fastboot.
I'm thinking...may be the default su (the one i get when i use MIUI's root manager) is under /sbin/su, that's why tsu is referring to that path, and adb root would referring to it as well, but it's not there now, because SuperSU is installing su at /su/bin/su? Not sure if this theory is right...
Any ideas? Thanks!
You may try tsu. It is working for me.
Please, give it a try:

Zebra TC56 Android 6 Marshmallow superSU

Hi,
I need to root a Zebra TC56 to install some other apps that require rooted Android. There is very little information in the way of rooting the Zebra TC56. I 'm pretty set on using Chainfire's superSU, but I cannot find any information on whether it will work on this hardware. Does anyone know if the superSU works on this device with Android 6? If not, is there another Root Tool that will work.
Any advice appreciated.
THANK YOU!

1. Install BusyBox applet-suite what contains the SU-binary
2. Install latest SuperSU APK

BusyBox installed fine.
SuperSU will not install all the way. When I select to root, it says root not detected and then, "How to Root", which launches my browser to a site that no longer exists.
Now what?
Thank You!
edit: Still stuck at this point. I read about TWRP, KingoRoot and some other random apps. I cannot brick this touch computer; it is $1600; that would be a very expensive brick. :crying:
So, I have no idea if I am right, but maybe I need to open the terminal emulator and "su" install the SuperSU apk. But I have no idea and I don't want to experiment. Hopefully, someone can help me.

Don't confuse things:
SU is the super user who unrestrictedly can perform any operation on Android OS. As soon as SU got installed Android is rooted! Again: BusyBox you successfully installed contains the su applet.
SuperSU is merely a root-manager app: it maintains a database where is stored what app can act as super user. SuperSU app doesn't grant super user rights.
BTW:
TWRP has nothing to do with rooting device's Android, as this is also true with Magisk.
The device is still not rooted after the "BusyBox Installer (No Root)", from your link, was installed.
I installed BusyBox, I followed the directions to then copy a command, then open a terminal, paste the command in and hit enter, then nothing happened. SuperSU was not installed with it.
So, as you told me, I then installed the latest SuperSU APK from your link. It says it installed, but when I run it, it says root not detected and then has a link named, "How to Root", which launches my browser to a site that no longer exists.
I followed what you said. Where did I go wrong?
Thank You!
You didn't get it. Sorry to say this.

Didn't get what?
I installed the BusyBox you gave me the link to.
I semi-installed the SuperSU you gave me the link to.
SuperSU did not fully install, because the Android is NOT rooted..
BusyBox had no SuperSU as part of it --the file you said to use even says "BusyBox Installer (No Root)".
(That should have tipped me off right away you had no clue, but I thought maybe you knew something.
So, you gave me the links for both of those files and it doesn't work.
I don't think you have any idea what you are doing; and shouldn't be explaining things you do not understand.
The "no root" BusyBox, does not include SuperSU.
If it did, why did you give me the link for the separate SuperSU file?
All the "no root" BB did was install a terminal emulator (with no su abilities).
The SuperSU didn't install, because the Android is NOT rooted.
If the Android WAS rooted, SuperSU would run and allow me to grant su privilges to the apps that require it to work.
You basically just wasted my time.
I would have just said "thank you" and moved on, but you are rude.
You don't know what you are talking about either.
Hopefully, this will help others, to not do what you say to do.

You're right: BusyBox (No Root) doesn't come with SU-binary. Wasn't aware of this. I misinterpreted APK's title. Pitty.
ERRARE HUMANUM EST ( To err is human ).
Installing BusyBox containing SU-binary requires your device's bootloader got unlocked before, because Android's /system partition gets modified. Hence manage to unlock device's bootloader as 1st thing of all things. Good luck.
DL BusyBox latest: https://github.com/meefik/busybox/releases/download/1.31.1/busybox-1.31.1-46.apk
My last 2 cents here: SuperSU and SU binary are totally different things.
