[devs][unsolved] just coping init.d script in its folder works - LG Optimus Black

hey devs , i came above something made me thinking , if i just copy the init.d scripts in their folder in a rom made of flashable zip ex.cm10 the permition of these files doesnt be the same if i install the musing pimp my rom aroma ,, is these permition neccesary to scripts to work ??, if yes how can i set them right

Permissions are important yes (Sometimes more permissions than necessaries are given to account for differences across devices and they will change per script)
Are they not working, since your asking?
If they aren't run, there are a few things I can think of.
You need to mod the ramdisk to run the scripts on startup or make a file that is already being run on startup to run the scripts in init.d. (CM10 already has it included, don't think any repack got it included - didn't check all of them, so some might have)
The permission the scripts are being run at are the same as what the permissions are from what executed them. Most tweaks need to be run from root so make sure that they are being executed as root if they don't need to be executed as root and aren't run with root permissions make sure that they have sufficient permissions to be run as that user.
Making init.d scripts run a echo command to a file is a good way to check if they are being executed.
And that's what I can think of at the moment.

ok so how can i apply their permitions from the zip of the rom ,, what lines should i add to the updater-script that fixes their permition ? ,, also im using cm10 as a base so its ok with the ramdisk

Code:
set_perm(0, 0, 0755, "/system/etc/init.d");

this to be in the updater-script right ??..
,, i already have these both lines in my cwm script
set_perm_recursive(0, 2000, 0755, 0755, "/system/etc/init.d");
set_perm(0, 0, 0755, "/system/etc/init.d");

in your code perms are set two times (first line is useless I think and may apply wrong perms on the etc dir). I don't have much knowledge about these kind of scripts, but I can say that the recursive parameter is used for direcories. also, perms have to be set at the end of scripts (before unmountin of course) so they're applied permanently.
it must be something like this (in short) :
Code:
# mount
run_program("/sbin/busybox", "mount", "/system");
# remove previous bin
delete("/system/etc/init.d");
# copy file from source
package_extract_file("system", "/system/etc/init.d");
# ser perm
set_perm(0, 0, 0755, "/system/etc/init.d");
# unmount
run_program("/sbin/busybox", "umount", "/system");

[Q] redbend error in updater-script

No views? Cmon
mount("MTD", "system", "/system");
package_extract_file("redbend_ua", "redbend_ua");
package_extract_file("zImage", "zImage");
set_perm(0, 0, 0755, "redbend_ua");
run_program("redbend_ua", "restore", "zImage", "/dev/block/bml7");
(from voodoo script, working for me)
Okay, will try to mount system first. But i dont think that this is the error -.-
And the other lines are the same from mine...
Doesnt work. Still the same error...
Exchanged the update-binary with the one from Voodoo and now it works. ****, i have to learn how to compile my own update-binary. Help in this?

CWM code questions

I don't like flashing things without knowing what do they do.
So it helps that I'm a programmer by day, and I make it a point to look at the code of the scripts I'm CWM-flashing.
I downloaded a modem from Perka's stash and I'm not sure what I'm looking at with this one:
Code:
package_extract_dir("updates", "/tmp");
show_progress(0.100000, 10);
set_perm(0, 0, 0755, "/tmp/redbend_ua");
set_perm(0, 0, 0777, "/tmp/redbend_ua");
run_program("/tmp/redbend_ua", "restore", "/tmp/modem.bin", "/dev/block/bml12");
set_perm(0, 0, 0777, "/tmp/redbend_ua");
run_program("/tmp/redbend_ua", "restore", "/tmp/zImage", "/dev/block/bml7");
show_progress(1.000000, 0);
I'm unsure about a few things here:
1. Why is there a need to chmod redbend_ua twice, and then again after running it?
2. We've run the first run_program, and we have a modem. Lovely. Why is the script then messing with the kernel? Especially since there isn't a kernel in this package. I have a suspicion this is simply a sort of template package, and you can put in a kernel, modem or both and it will work, but I'm unsure about this. (Also, how would it react in the case of a file being missing?)
On the whole - What scripting language is this? Where can I find a proper documentation for it? How do I create one myself? I've googled it plenty and didn't seem to come to a proper conclusion..
Why dont you PM Perka himself/herself? she/he would be the best person to answer your questions!!!
Good Luck

[tutorial] creating simple update.zip

creating simple update.zip is very easy if you know all the basics
some basics are as follows
1. folder structure
*META-INF (compulsory)
*system
*data
many folders can be added but for simple update.zip these three are required.

2. META-INF folder structure
META-INF> com (certificates lies here)
META-INF> com> google
META-INF> com> google> android (updater-script and update-binary lies here)
Click to expand...
Click to collapse
3. update-binary:-
created in C language cannot be created by anyone, it handles every command which is written in updater-script and do everything from extraction to writing image files
Click to expand...
Click to collapse
4. updater-script:-
this file contains all the commands which are needed to do the work, basic commands are provided below
Click to expand...
Click to collapse
5. update-script common commands:-
Code:
ui_print("");
# put the lines in between "" what you want cwmr to show while flashing
e.g ui_print("text by DHLALIT11");
-------------------------
Code:
show_progress(0, 0);
# before comma is the number by which you want to increase the progress, 1 is complete 0.20 is 20%, after comma is the time until which progress bar will keep progressing when time will be completed progress bar will show 20%
e.g:- show_progress(.50, 5);
-------------------------
Code:
mount("ext4", "EMMC", "/dev/block/stl12", "/system");
# command is used to mount system without mounting nothing can be copied to system (will not work on rfs file system
-------------------------
Code:
package_extract_dir("folder name", "/path");
# this command is used to extract the files which you have copied to system folder of the package to the system folder of the phone
(e.g:- package_extract_dir("system", "/system");
-------------------------
Code:
run_program("/sbin/busybox", "mount", "/dev/block/mmcblk0p2", "/data");
# command is used to mount data without mounting nothing can be copied to data (may not work on rfs file system )
-------------------------
Code:
package_extract_dir("data", "/data");
# this command is used to extract the files which you have copied to data folder of the package to the data folder of the phone
-------------------------
package_extract_file("path/to/file", "/path/to/extract");
# command is used to extract the script or any other file to temp folder.
e.g:-
Code:
package_extract_file("script/tool.sh", "/tmp/tool.sh");
-------------------------
Code:
delete_recursive("folder name");
# use to delete a complete folder that can be system, data, cache etc.
e.g:- delete_recursive("/system/media");
# will delete media folder from /system
-------------------------
Code:
delete("file with complete patch");
# use to delete a single file
e.g:- delete("/system/app/app.apk");
# app.apk will be deleted from /system/app
-------------------------
Code:
set_perm(0, 0, 06755, "/system/xbin/su");
# this command is used to give permission to a file, in this scenario we are giving permission to su file to make it work properly.
-------------------------
Code:
set_perm_recursive (1000, 1000, 0771, 0644, "data/app");
# this command is used to give permission to the whole folder, in this scenario we are giving permission to app folder to make it work properly.

------------------------------------
the file you want copy to system or data through update.zip must be placed in the system or data folder of update.zip along with the folder structure
suppose you want to install busybox then the file must be placed like this:- update.zip> system> xbin> busybox
want to install YouTube as system app then the app must be placed like this:- update.zip> system> app> YouTube.apk
want to install YouTube as data app then the app must be placed like this:- update.zip> data> app> YouTube.apk

OK, Thank you very much for this quick tutorial. It's so useful for me
I think you should add it to your signature to point out it (I didn't notice it untill you had mentioned it in my topic).
I think also you may add some more commands for Updater-Script.
Q: Can I get input from user via CWM? ^_^
I don't like to update my sig with my mobile and am away from my computer from about 1 week don't know when I will update it
Nice.
It should give noobs a guide to modify roms to their liking instead of asking rom devs to remove this and add that,now they can edit the rom themselves and with rootexplorer do it all from your phone.
updated op, there was a mistake in show progress command please read it again
thank.. i found what i need
I finally found this tutorial, as I suspect, like copy-paste it in the same directory.
*sorry for my bad english*
what you want to copy and paste in the same directory
Very well written tutorial !!!. Was very easy to understand.
...
@dheeraj (dhlalit11)
This script is called "edify" script. This is just a suggestion because you have not mentioned it in your tutorial.
...
...
Is it possible to set properties of "build.prop" file from updater-script?. From terminal we can use "setprop" command, is there similar command that can be used in the updater-script. Or may be some busybox command i.e "run_program(...)" ???
you will need to create a script then create its flashable zip in updater-script first extract it to /tmp, make it executable then run it through run program command
awesome............
done editing
guys any fixing needed please reply

P.S: what permssion should be set for the superuser binaries?? i am confused between 06755 and 04755

Just remove it n at last '#' is used for command line!!
from the first command remove the yaffs2
that busybox mount command will mount /data
the permission should be 06755
and also remove those getprop lines they are useless
Please tell permissions for frameworkres.apk

[Fixed] Error Flashing two flashable zips I created

I created two flashable zips that I'd like to use after every rom flash:
One is all my Layers overlay apks and the other is all the font files I want to use.
Here is my updater-script that I use in both zips, the only difference being the ui_print and file names, of course:
Code:
ui_print(" Installing Layers overlays... ");
ui_print(" ");
show_progress(0.99, 30);
run_program("/sbin/busybox", "mount", "/system");
package_extract_dir("system", "/system");
set_perm_recursive(0, 0, 0644, "/system/vendor/overlay");
show_progress(1.0, 1);
unmount("/system");
ui_print("----------------------------------------------");
ui_print("| Done!!! |");
ui_print("----------------------------------------------");
ui_print(" ");
And here is the error I get in recovery when I flash either zip:
Code:
set_perm_recursive() expects 5+ args, got 4
E:Error executing updater binary in zip '/sdcard/Mods/Zips/Layers-Themes-signed.zip'
Error flashing zip '/sdcard/Mods/Zips/Layers-Themes-signed.zip'
Obviously, I did set
Code:
set_perm_recursive(0, 0, 0644, "/system/vendor/overlay");
to be the right permissions. I know that the contents of that directory, /system/vendor/overlay need to be 644 but I don't know the proper edify script syntax for
Code:
set_perm_recursive(0, 0, 0644, "/system/vendor/overlay");
Does anyone know what I need to do differently to make these zips flash properly?
EDIT: I found this post that said that the correct syntax should be: set_perm_recursive(0, 0, 0755, 0644, "/system/vendor/overlay"); instead. Problem solved!!
I know you figured it out, but the set_perm_recursive needs 5 arguments (as stated in the error message you received). It would be for group:user ownership and then permissions for directories & files (in that order) followed by the directory that you're setting permissions in.

[Help] How overwrite a file in system/bin with Safestrap, with no rooted phone

Hi mates, I need your help, thank you!
I would use my old phone (g900v cdi11 locked bootloader) as a videosurvelliance camera, to do that I need that it can reboot automatically if battery runs out and power appears again. To do that I need to change lpm file inside /system/bin folder, switch off phone, plug the power abd check if script lpm file works, if not edit it and check again. . To do that I have these ideas:
1) flash a rooted LL rom, and use a root file manager and overwhite lpm file, is it that easy and possible?
2) Boot on safestrap (which I've already installed and accessible flashing the KK bootloader with Odin, the version is about 2.7.4, don't remember exactly) and chage from there, but the SS file manager don't see any files, probably it's running not rooted (??), maybe /system not mounted, and I don't know all the Unix command I've to type in console to edit lpm or overwrite it, or eventually with ADB.. it copied but in reality I don't know where, it's not /system/bin.
3) so I need to "flash"/install a .zip file containg the /system/bin/lpm file, but for doing this I need a script, which is actually what I'm asking here
4) Any other ideas? Please remember I have a cid11 g900v, so no root on MM, and some other complications unfortunately.
For the script I've tried to arrange from one SS installation, and I tried to save only these lines, but I'm not sure it will do the job, the idea is to create a zip file with system/bin/lpm file and META-INF/com/google/android/updater-script file:
Code:
ui_print("*************************************");
ui_print("* Change lpm *");
ui_print("*************************************");
ui_print("");
unmount("/system");
ui_print("Writing System Files");
mount("ext4", "EMMC", "/dev/block/platform/msm_sdcc.1/by-name/system", "/system");
package_extract_dir("system", "/system");
set_progress(0.600000);
ui_print("Setting Permissions...");
ui_print(" ");
#PERM
set_metadata_recursive("/system/bin", "uid", 0, "gid", 2000, "dmode", 0755, "fmode", 0755, "capabilities", 0x0, "selabel", "u:object_r:system_file:s0");
ui_print("------> Done!");
unmount("/system");
ui_print(" ");
ui_print(" Installation complete ");
ui_print(" ");
ui_print(" ");
What is missing eventually?
Thank you!
By the time I solved flashing every time the whole rom (exploded, edited and repacked in Windows), boot It and wit its installation.
It still interesting to read your suggestions, thank you
