How to edit system files?

Perhaps noob question, but i want to take a look at system files (button-backlight for instance) and play/edit them. But I don't have a clue how to do that.
I'm using root explorer and super manager.
I'm having root and am able to get adb shell (learned myself some adb commands
Thanks!

[TOOL & HACK] unlock your SIM FOREVER (ICS & JB)

Hi guys, I understand that some of you are unhappy with this sim lock because you want to test the latest JB leak . so here i ve a solution for you.
DO IT AT YOUR OWN RISK !!!​
Precaution:
-* don't use voodoo app after using this mod or any other mod, (if you want use other mod restore your original efs file).
-** Before to update to a new build (like the coming stable JB) restore your original efs.
*, **, in the case you got the phone unlocked you can always use my mod to unlock it :good:
HOW TO UNLOCK
- First you need to backup your "EFS FILE" in safe place.
- you must be in unlocked stock firmware like BLG8 (using voodoo app + libsec-ril.so (mike1986 fix))
- unzip the attached zip "efs.zip"
- copy the files (.nv_core.bak, .nv_core.bak.md5) to your EFS file
- reboot and enjoy !!!
NOTE: applying this mod will not change your imei.
Backup & Copy & Past & Reboot ....easy
This MOD will remove the lock completely.
Don't tell me what i did because SAMSUNG ......is UNHAPPY
JUST CLICK ON THANKS

Is there something lost in translation?
"before backup this efs"
I think you mean backup efs before doing this?

Backup before root.

I have a g note with almost 2 years warranty. I want to root and change the ROM.
My question is how to backup important files and details such as csc files, that file containing imei number just in case if I had to return it to Samsung in state like it is right now.

You don't have to backup anything (rooting don't wipe) but if you still want to backup apps then use any app backup application from Google play and the folder you are talking about is efs folder, you can't backup efs without root.
First root and then backup downloaded apps and data using Titanium backup and , you can backup efs by using some efs backup tool. Check dr,ketan's toolbox in first link in my sig.

Thanks a lot mate. And what about my csc code? I should write it down or save it some how?

You can save the csc folder from system to SD using root explorer after root or check this for more info.

I need sample nv_data.bin ?

Anyone can help me to restore my IMEI and GSM working ?
Probably during error in flashing I've lost /efs data.
I have nothing there. Please help me....

Please double check where you are posting before starting a new thread. Good luck!

Thx for your reply, but unfortunately I've tried restocking using Overcome from the link at your signature.
But it doesn't help, IMEI is still 0044XX

what was the first thing you did that broke the IMEI?
If it was broken after installing CM9/10, then your sdcard will have a backup folder with efs folder and efs-xxx folders.

I don't know anymore, I flash a few ROMs and only then do I notice the GPS not working and IMEI is now 0044XXX.
I've restock a few times with overcome and re-partition, therefore all backup are already lost.

I found some in external SD as well.
and those aren't wiped by any repartitioning or ROM install.

Ooh, where do you find the file ? In backup folder ? I don't have backup folder at the external sd

Yes. Backup folder.
Sorry. That means you dont have a backup.

open titanium backup and go to backup/restore tab which is just next to overview (default view) select the app and click uninstall and press ok on all the warnings. only remove bloatware and not any system app or file.

Does the above mentioned link solve only for the rooted devises? Ive downloaded TB, and it is not able to get root permissions on the stock rom. :crying:

Yes.. Only for rooted devices. TB requires root access. As a matter of fact if you want to remove any of the system apps you will need root.
