Hello everybody,
I rooted my dream phone with :
Code:
fastboot boot boot.img
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# cd system
# cd bin
# cat sh > su
# chmod 4755 su
All work fine !
I tried to install busybox like this :
Code:
adb push busybox /data/local/tmp
cat /data/local/tmp/busybox > /system/bin/busybox
chmod 4755 /system/bin/busybox
No problem with this step, but now if I type :
Code:
$su
#busybox ls /data
I have a permission denied
If I type
Code:
$su
#ls /data
all work fine
(ls is an symbolic link to toolbox)
ls -l /system/bin
Code:
-rwsr-xr-x root root 1745016 2009-07-28 11:01 busybox
-rwsr-xr-x root root 86936 2009-07-28 11:11 su
-rwxr-xr-x root shell 68472 2009-03-03 22:31 toolbox
...
I think busybox is not launch with root permission.. why?
I tried : ln -s busybox ls
but same problem !
What is wrong ?
Thanks.
Any particular reason why you setuid busybox? Try chmod 0755 busybox; chown root:shell busybox
it has already been said multiple time su has to be chmod 4755
but is as also to have these credentials: root.shell
mine was root.root so as a shell user you get an "access denied."
so a chmod root.shell /system/bin helps
after you need to re-chmod 4755 has it's loosing +s.
Also, if you pushed su to /data/local/bin, do this:
rm /data/local/bin/su
Because normal shell looks in /data/local/bin BEFORE /system/bin. It's part of the path.
thanx
my terminal now works as root
I've removed "m7" and "su" from /data/local/bin after root thanks to coolbits.
Hi Android Gurus,
I am new to android and rooting. I tried to follow the steps available in the xda forums to root my kindle fire HD 7". But instead of just executing the scripts, I chose to read the scripts and manually execute them comand by comand so I could learn. In the process I did what seems to be like a terrible mistake by setting the wrong permissions on /system/xbin/su like below instead of 06755
-rwxr-xr-x root root 380532 2013-01-03 00:24 su
Basically I cannot su anymore, hence I cannot mount the /system rw to modify su's permissions (sounds like a chicken-and-egg situation here).
I badly need help and appereciate if some of you can provide a way.
Thanks.

So you can not perform:
adb shell chown 0.0 /system/xbin/su chmod 06755 /system/xbin/su
What happens when you attempt to run these commands? If not, your real option is to go to our thread
noted below and use Root MANY ANDROID! to fix it.

I also tried to copy su binary again to /data/local/tmp again to see if I can recreate su ownership/permission but I'm unable to do that as well

xdajunior,
Yes, both Root MANY ANDROID! and Qemu will solve your issues. Then you can take a peek
inside the batch files to see how they get the job done. Since you are in a pickle, you
really need these utilities. Be sure you download these utilities from our site, there are
minor bugs in the original versions. If you have any questions, let me know, I love to
teach people and would be willing to offer you some free phone support. This time
would be spent teaching you some of the aspects of the Kindle and Android. I
will be around all day tomorrow, from 11am to 10pm PST GMT -8. Sorry for the
delayed repose I was on an emergency call most of the afternoon.
Hello.
I have system.img 5.0.2 for Lenovo S60. Bootloader is secured.
system.img: Linux rev 1.0 ext4 filesystem data, UUID=57f8f4bc-abf4-655f-bf67-946fc0f9f25b (extents) (large files)

HiJacking of the bin/app_process64 cause that phone won't play bootanimation and does not start launcher but i can see internal memory MTP Device.
SuperSU apk still warn: There is no SU binary installed and SuperSu cannot install it.
i have same problem with a cheap chinese **** (MTK based 4.4.2) I'v been readed the raw system.img with spt. Mounted it under linux copy the files like this (and of course checked in the supersu install script) and after rewrite the system, every files in the right place but i get the error: "You need manual reinstall the su" or something like that
Any idea?
---------- Post added at 09:52 PM ---------- Previous post was at 09:47 PM ----------
ok, my fault sorry
here is the tutorial
http://su.chainfire.eu/#embed
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..
