Q: remove su binary

I have root my P8-Lite ALE-L21 with supersu.zip through twrp recovery. after that I've installed KingoRoot and KingoRoot replace my su binary with some other su that is old for my android which is Android 5.0.1 and not working, so I had modified supersu.zip and put su binary into another directo...

5.0-lollipop rooting adb unrooting superuser

What does ./data/local/su -c rm /system/xbin/su do?

still rm: /system/xbin/su: Operation not permitted

Give us the result of mount and see Unable to delete file, even when running as root

this is mount result: omidgfx.com/mount.txt and i've tried the chmod but same error comes out

I see. Can you give the result of lsattr /system/xbin/su? I don't think Android has lsattr. You would need busybox in that case.

2:30 PM

for installing busybox my device needs to be rooted healthy, but my root is damaged and not working, is there anyway to install busybox with adb ?

and after that, busybox using su binary in system/xbin not the one i've installed

you can put the busybox or toybox binary under /data/local/tmp/ and call it this away: ./data/local/tmp/toybox lsattr /system/xbin/su

ow, thanks so much, i will do that right now

Make sure you rename the binary to toybox or busybox before pushing it. Also make sure that the binary has executable permission.

sorry i'm really amateur in this proccess, how do I make executable permission ?

Which OS are you using on PC?

2:36 PM

windows 8.1

Anyhow, after pushing the binary, do adb shell ./data/local/su -c chmod 755 PATH_TO_BINARY

ok

hmmm, ive a question

yes

can i make a full backup in twrp and then remove su binaries from that backup and then restore it ?

yes, of course.

2:39 PM

is that even possible

wow !!!

hold on

Make sure you find out how to mount twrp backup in read-write mode on PCor at least on Android

isn't that a zip file ? can i just remove binaries with winrar ?

I don't how about that. I've never tried editing TWRP backup.

ow, so please stay i will make that toybox and doing first idea before backup

so so sorry i'm bothering you

sure

it's not bothering. We don't find many users who actively engages in solving their own problem or at least cooperate nicely.

2:45 PM

really thank you

toybox has been installed and works fine, now what do you need ?

is it working?

yes

but lsattr is a unknown command for toybox

sorry i'm from iran and my english is so bad.

strange. when you run toybox, among all the entries do you not see lsattr. I see it next to ls.

basename bzcat cal cat catv chgrp chmod chroot chvt cksum clear cmp
count df dirname dmesg echo env false free head help id insmod kill
killall link ln login logname ls lsmod mkdir mkfifo mknod mkswap mktemp
mountpoint nc netcat nice nohup oneit patch pidof printenv pwd realpath
rmdir rmmod seq setsid sha1sum sleep sort swapoff swapon sync tac
tail tee true truncate tty uname uniq unlink unshare uptime vmstat
wc which whoami xargs yes

this all are available commands

And you've downloaded it from here: landley.net/toybox/bin, right?

2:49 PM

loock i've installed 0.3.1 version, the other versions have no armv7l

is it ok to use armv6l ?

Try it. It doesn't hurt. Mine is 0.6.0

ok just a sec

works and this is the result for /data/local/tmp/toybox lsattr /system/xbin/su /data/local/tmp/toybox lsattr /system/xbin/su :

-----a-A----- /system/xbin/su

hold on for a minute.

I think this Operation not permitted in linux, is for when we trying to access some files they belong to another users, i read it somewhere but not so sure, can it be a reason ?

ok sure.

what does ls -l on /system/xbin/su give?

2:56 PM

-rwxr-xr-x root root 315968 2015-12-30 12:26 su

do ./data/local/su -c chattr -a /system/xbin/su

now give me the new result of previous lsattr command again.

tmp-mksh: chattr: not found

./data/local/su -c PATH_TO_BUSY/TOYBOX chattr -a /system/xbin/su

nothing happened

Give me the new result of that lsattr command.

3:02 PM

/data/local/tmp/toybox chattr -a /system/xbin/su

no.

this is my command and this is my result:

/data/local/tmp/toybox chattr -a /system/xbin/su

Okay, follow step by step what I'm telling you now.

I

do: ./data/local/su -c /data/local/tmp/toybox chattr -a /system/xbin/su

3:04 PM

i did but there is no result

it's ok

Now do: ./data/local/su -c /data/local/tmp/toybox lsattr /system/xbin/su

-------A----- /system/xbin/su

Now do: ./data/local/su -c rm /system/xbin/su

wow

it works

su was removed

Sure, now follow that chattr command on other su file as well and try rm then.

I'll explain in my answer the problem you were having.

3:07 PM

I I captain

so so so so so thank you

sure, just make sure you remove all those su remnants and copy that new su from /data/local to /system/xbin.

When done with that, reboot and see whether apps detect your new su.

Ping me about the status

ok just a sec

it works fine, but for sure i flash it with not modified zip file again. still working fine

alright then. good for you. I'll post the answer shortly.

thank you so much

no problem.

Are you here? I need to ask something.

Which toybox worked for you?

3:16 PM

armv6l

okay.

v 0.6.0

it's a big help for me, may we be friends ?

No, please don't do that. Delete it because the chat room is public and google indexes it

Relax, you can find me on the chatroom of the site. [chat]

I, I, captain

are you making answer? im waiting for that, so i can accept it

It'll take a bit of time. You can engage in some other work of yours. Accept it later when you login or comeback. I'm just finding out the difference between -a and -i. The a means append only. It was causing rm not able to delete that file. I'm just doing some searching about that.

3:25 PM

ok, thank you again
