Hey people,
I've got a problem here...
Whenever one of the apps of my custom rom needs root permissions, I get the usual SuperSU-prompt. But even if I accept the request, the app won't gain root permissions.
This problem occurs with several different apps.
Is it possible that SuperSU does not have root access?
My rom has prober su symlinks in its updater-script..
At least I think so.
delete("/system/bin/su");
symlink("/system/xbin/su", "/system/bin/su");
set_perm(0, 0, 06755, "/system/xbin/su");
So, got any ideas how to solve my problem?
Thx in advance.
Is it working for some apps, and not for others? Or, are all apps not getting root access?
You could try updating the su binary, or fixing permission from recovery, for starters.
AW: [Q] Root permission granted - App still does not have root?
It is working for no app.
And the su binary should be alright, as I've taken it from a working rom of the same version.
Fixing permissions?
Hmm, I could try that.. Wait one.

Seems there is no option to fix permissions in CWM Recovery v2.5.0.7.. :/
Anyway, I'd prefer to fix the issue in my rom.
So, what permissions does the su binary need in an updater script?
Ahh, I've found the solution! :laugh:
My updater script looks like this:
[...]
delete("/system/bin/su");
symlink("/system/xbin/su", "/system/bin/su");
set_perm(0, 0, 06755, "/system/xbin/su
[...]
set_perm_recursive(0, 2000, 0755, 0755, "/system/xbin");
[...]
I think the issue was caused because set_perm_recursive overwrites the permissions for system/xbin/su..
So my superuser binary didn't have the right permissions.
Moving these lines at the end of my updater script solved the problem.
delete("/system/bin/su");
symlink("/system/xbin/su", "/system/bin/su");
set_perm(0, 0, 06755, "/system/xbin/su
By the way, fixing permissions in recovery would probably also fix this issue..
Glad you got it working.

In dsixda's kitchen, i enabled init.d scripts support but i can't find any folder in /system/etc. I tried creating a folder name "init.d" and flash my rom, but the scripts would not run. Anyone can help me

Well, maybe you could try use some other startup-init scripts. I am NOT android developer but LINUX developer, so i suppose that android-modified kernel still uses Linux-style boot sequence.
Maybe you could try to create this file
/etc/rc.local
its text file, in this file you can store your bash script, everything us executed with superuser permissions so avoid using su.
Another deep-system file is /etc/inittab, but you should avoid modifying this file unless you know, what you are doing.

Do you have a (working) busybox installed?
How are the scripts called (the filenames)?

1.Yes
2. example: 00banner
Ok, i added some permissions into updater-script for the scripts copied from other GB roms and edit them.
Code:
set_perm(0, 0, 0777, "/system/etc/init.d/00banner");
set_perm(0, 0, 0777, "/system/etc/init.d/01zipalign");
set_perm(0, 0, 0777, "/system/etc/init.d/02zipalign");
set_perm(0, 0, 0777, "/system/etc/init.d/03ramscript");
set_perm(0, 0, 0777, "/system/etc/init.d/04sdcard");
set_perm(0, 0, 0777, "/system/etc/init.d/05loopysmoothnesstweak");
set_perm(0, 0, 0777, "/system/etc/init.d/06screenstate");
set_perm(0, 0, 0777, "/system/etc/init.d/07sysctl");
set_perm(0, 0, 0777, "/system/etc/init.d/99complete");
and this too
set_perm_recursive(0, 2000, 0755, 0750, "/system/etc/init.d");
set_perm(0, 0, 0755, "/system/etc/init.d");
Well, if you are sure you have not screwed up when adding init.d support in the kitchen, move to the relevant thread. The guy is very responsive.

Ok thanks
When I tried to create a CWM script for flashing certain mods on systemui.apk, email.apk and twwallpaperchooser.apk, after flashing permission of these apks are rw-rw-rw instead of rw-r--r--. I am not sure why this is happening and I have tried different scripts as well.
Code:
ui_print("");
ui_print("--------------");
ui_print(".XXXXXXXXXX.");
ui_print("--------------");
mount("ext4", "EMMC", "/dev/block/mmcblk0p9", "/system");
delete("/system/app/com.google.android.email.apk");
package_extract_dir("system", "/system");
set_perm(0, 0, 0644, "/system/app/com.android.email.apk");
set_perm(0, 0, 0644, "/system/app/com.android.systemui.apk");
set_perm(0, 0, 0644, "/system/app/com.sec.android.app.twwallpaperchooser.apk");
show_progress(0.100000, 0);
ui_print(".Sucessfully fixed all bugs.");
ui_print("----------------------------");
unmount("/system");
Please help me to set right permissions
have you tried permission
have you tried cwm then its either in advanced or on the first page theres an option that says fix permissions, depending on how many apps on phone could take 2-50+ secondsm. im no expert but whenever i change permissions and get them wrong this always reverts them back to default for me. or you could try using solid explorer, or root explorer to manually set permission with no scripting required.
good luck otherwise hope i helped
Hi all
I have been trying to make a flashable zip for my mod for jb 4.2.2.
I haven't really seen a detailed guide (exact steps) on how to achive this.... most of the threads are for CWM, the op of the thread attaches a sample.zip but its for CWM.
My problem is the update-binary. When I come to flash the file it give an error and quits the install.
My mod is to be written to the system folder.
Where do I get an update-binary file compatible with 4.2.2 if that is what I require.
I am willing to read/learn if there is a guide.
Thanks all

Hey there mate,
try the following method:
http://teamuscellular.com/Forum/topic/3488-how-to-make-flashable-zip-files-for-cwm-or-twrp/
Thanks for the reply mate. Yeah have read this post but still need to find out about the update binary file.
Again thanks

I'd recommend finding a flashable zip that already works for TWRP and replacing the contents of it with your mod.
That should work...
You could try this blank TWRP zip I use it for 4.1.2 so not sure if it will work with 4.2.2 as it stands.
If you rename it make sure you don't have any spaces in the naming format all words must be linked with a _ or - or something no gaps
Top work guys thanks alot for ya fast responses will try when I get in

i tried the attached file but as it starts its says
E: Error executing updater binary in zip
error flashing zip
this is on the internal memory.
this is the update script im using.... more that likely wrong...
ui_print("Lockscreen Clock Font");
show_progress(0.500000, 0);
ui_print("inspired by Delight CFW Font");
run_program("/sbin/busybox", "mount", "/system");
package_extract_dir("system", "/system");
set_perm_recursive 0 0 0755 0644 SYSTEM:app
unmount("/system");
ui_print("Reboot now!");
show_progress(1.000000, 0);
i took mikep99 advice and edited the script and put my info in
i busybox installed so am now a little stuck
Try with a ';' at the end of the set_perm line..
EDIT. remove the line completely and try.
EDIT2. That line should be:
set_perm_recursive(0, 0, 0755, 0644, "/system");

thanks for replying
i just tried the editions to the file and it did install this time but sent me in to boot loop... all restored in 127 seconds.... love TWRP lol just wish my mod would flash.
i am trying to flash the keyguardwidget.apk to the /system/app folder.
the set_perm line has had different values ive notice in other flash files, are mine correct for what im trying to do.
Its just file permissions. that wont cause a boot loop in itself

i tryed adding a couple of more lines but still boot looped.... after it flashes it says "fix permissions... looks like you are not rooted"
i just dont want to edit someone elses work.
Boooooooom!!!! done it :silly:
For all..... this line DID send me in to boot loop
set_perm_recursive(0, 0, 0755, 0644, "/system");
it should be
set_perm(0, 0, 0644, "X");
were X is the directory in the zip
thanks to all for your help

odd
The only thing I can think is that:
0, is /system, Next 0 is app, And the 644 is to the app itself.
Had to look at another flash file (gs4 keyboard)

Has anyone got one to boot on the Mega?
I have tried various ideas and have got the install working but it fails to boot after the reboot.
Is anyone further along than this?

No
Aroma bums out at handing over to the update script. The updater script works fine on its own this was tested on 2.00 2.5 and 2.76 the first two worked fine on n7000 so I know its not my scripting. I have mentioned this to the peeps eho know.
The only thing struggling to flash is kernel but as we need stock anway for the mo thats not an issue. But that will be easy to sort just ran out of yime yesterday
Whats the issue you facing in aroma or normsl update script. Can you post your script here

I have gone down the updater-script from the kitchen, I am having problems with permissions but I have got it booting now.
I am working on tweaks and bloat for now and trying them out.
What permissions you having probs with. Whats the issue

I have removed them.
I am down to this
Code:
set_perm_recursive(0, 0, 0755, 0644, "/system");
set_perm_recursive(0, 2000, 0755, 0755, "/system/xbin");
set_perm(0, 1000, 0755, "/system/xbin/busybox");
set_perm(0, 0, 06755, "/system/xbin/su");
set_perm(0, 0, 0644, "/system/app/Superuser.apk");
set_perm(0, 0, 04755, "/system/xbin/busybox");
Now just need to try it out.

I have got it now, thanks, I am working on the bloat now.
Hey peeps, I'm attempting things here. I'm trying to modify an update.zip file that installs properly on my device. I'm mostly trying to get root access on this device.
So far in this little weekend project, I have already put the su binary in the system folder within updater.zip. So I have found that I need to edit a updater-script file.
I have found this line:
Code:
set_metadata("/system/xbin/su", "uid", 0, "gid", 0, "mode", 06755, "capabilities", 0x0, "selabel", "u:object_r:su_exec:s0");
This is here because this tablet already has root but is not in a place where supersu can find it. So, I already have the part where it copies the su binary into /system/bin.
So how should I set the permissions with this command?
