RE: JWR66N.S005.130625

This build has the following kernel options enabled:

CONFIG_SEC_RESTRICT_ROOTING=y

CONFIG_SEC_RESTRICT_SETUID=y

CONFIG_SEC_RESTRICT_FORK=y

CONFIG_SEC_RESTRICT_ROOTING_LOG=y

This is why root mostly doesn't work. Other development firmwares from Samsung have had this set as well, and did not allow root, though later released retail firmwares did not have (all) of these options set, and did allow root. I would actually expect the official release to allow root as usual (but who knows).

It is by no means impossible to bypass this, it is however almost 1 AM and the weekend has started, so ... :)

If you only install SuperSU's binary (using TWRP for example, or through rooted shell in CWM, or whatever) without the GUI, it will allow you root access from adb shell, by the way.

What's the file name ? 

Hitesh commented on 2013-06-28 at 23:26:

lol Thanks Randy. 

Greg W. commented on 2013-06-28 at 23:37:

So the development builds where root might be useful to debug restrict root.  Samsung, what are you playing at here...

Роман Р. commented on 2013-06-28 at 23:52:

Блядь как же хуёво и нечестно, что i9500 сосёт хуй.

Hitesh commented on 2013-06-28 at 23:58:

ok so this is in config.gz, but I have no idea how to make a boot.img out of it.

S4的4.3这么快？N4的呢？

Michel T. commented on 2013-06-29 at 01:01:

@J Mulla It's not an info to download something ;)

Kyle R. commented on 2013-06-29 at 02:27:

I've unpacked the kernel and cannot find those anywhere, granted i'm new at this but trying. would you be able to point me in the right direction? I'm opening every last RC or SH in notepad++ and can't find anything

Thanks for the help if you manage to respond.

Kyle R. commented on 2013-06-29 at 03:11:

well i'd like to give it a shot, any pointers?

Ruxi W. commented on 2013-06-29 at 03:50:

so now can't get root?

任义 commented on 2013-06-29 at 05:19:

how to get root？

Rohan M. commented on 2013-06-29 at 05:29:

4.3???

Harald H. commented on 2013-06-29 at 05:37:

config.gz is not something you can change and repack. config.gz just contains the compile settings, with which the whole kernel was built.

Markus M. commented on 2013-06-29 at 12:28:

Good job.. Thx

David F. commented on 2013-06-29 at 13:39:

Esteban Z. commented on 2013-06-29 at 15:22:

Sergiy S. commented on 2013-06-30 at 00:30:

+The Watcher . You have ANOTHER QUESTION from said bensouda to answer.... :-)

Esteban Z. commented on 2013-06-30 at 03:09:

+The Watcher . You are telling me something I already know pal. My question is: This post is related to which specific model of the Galaxy S4? I do not see how I can identify which one is CF talking about here since he doesn't state the model specifically.

Errol R. commented on 2013-06-30 at 03:28:

There's only one model the firmware was made for, there are other models with identical hardware which is very specific and even broken down in a few points of this post, which model DO YOU think it is?^ The technical aspects of Android isn't for everyone.

paul s. commented on 2013-06-30 at 05:11:

When is the note2 getting anything?

Martin E. commented on 2013-06-30 at 06:52:

The i9505 is exactly the same, isn't it? Hardware wise, that is.

Amin H. commented on 2013-06-30 at 07:43:

Wow great!!!

Mustaq A. commented on 2013-06-30 at 12:43:

Can you build a cm for it that would br great.

Edo commented on 2013-06-30 at 12:57:

Jacob B. commented on 2013-06-30 at 18:50:

Anh T. commented on 2013-07-01 at 03:49:

can you port this to note II?

Janet B. commented on 2013-07-01 at 18:03:

yes you can I got the same phone iPhone 5

Adnan H. commented on 2013-07-01 at 21:08:

+Chainfire I tried couple of methods to obtain root. 

First one that came to my mind is to restore backup of my root using "OTA Root Keeper", I used this method couple of times back in the day and it worked. 

It worked pretty good except the fact that it couldn't get root permission granted: http://goo.gl/LTaE7

I figure this is due to addition of "SELinux" with Android 4.3.  

To go around this, in adb shell mounted the /system then pushed su to /system/xbin/su and Superuser.apk (also tried with *.zip).

However, I failed on step where I tried to do:

chown 0.0 /system/app/Superuser.apk && chown 0.0 /system/xbin/su

I'll try with couple of more things tomorrow, if you have any ideas or suggestions do let me know :)

Mike C. commented on 2013-07-02 at 11:00:

Love ur work mike from sa will support u

Adnan H. commented on 2013-07-02 at 11:31:

+The Watcher . the way it's going we might end up having custom kernel for Stock ROMs in order to have root access ...

李杨 commented on 2013-07-03 at 09:32:

can this be ran on nexus 4？？
