Can someone knowledgeable please submit a detailed post, which instructs how to remove any files added during the Root Process, as well as any other file permission changes or modifications of any other type?
I see many half assed posts in these forums made by unqualified members, which are nothing but a waste of time and clutter this great resource. I would appreciate it if this post could be addressed by those who truly understand this process.
The file that was used to Root the SCH-i905 from Verizon was the one attached to this post.
Thanks in advance! This could be a great learning tool if answered properly.
Can some one please respond? Or is it that everyone is too scared to post helpful information?
Well, since no one was of any assistance, I was forced to piece together information and come to an understanding of how this works, and how to fully reverse what was done by this Root Update.
To begin, I would like to mention, that removing Superuser.apk from the /system/app folder, along with 'su' from the /system/bin folder, will negate your Root Access, and put you back to your default levels of access. This will prevent Mobile Device Management Solutions, such as AirWatch, Zenprise, or MobileIron from detecting your device as being compromised.
I was not successful in removing these two files via the ADB shell, however I was successful when using a Terminal Emulator App on the Device itself.
1.) I began by installing a free Terminal Emulator from the Android Market.
2.) Launched the Terminal Emulator and typed 'su' , then pressed Enter to gain Root Shell Privileges.
3.) From the Root Shell, I typed the following commands to remount the '/System' Directory to gain Read/Write Access.
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
4.) I typed the following commands to remove 'Superuser.apk' and 'su'.
cd /system/app
rm Superuser.apk
cd /system/bin
rm su
5.) Type the following command to remount the '/System' Directory back to Read Only.
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
6.) Sync your device with Google under Settings / Accounts & Sync.
7.) Reboot your device, and you are good to go.
It might be a good practice to perform a Factory Reset on your device after doing this, however this is not completely necessary. I tested the Air-Watch Agent installation after performing the procedure mentioned above, and the Air-Watch console no longer detected my device as being compromised.
I will add that on my sch-i905 I found the bin directory under system not under system/app. For me, replacing cd /system/app/bin with cd /system/bin did the trick but the rest worked a treat - thanks for the post!
Thanks for pointing out my typo. I corrected the path in my Post.
Thanks for this.
Does this restore the stock recovery that was replaced with Clockwork when the kernel.zip and recovery.zip files were flashed to obtain root? I do not totally understand the relationship between Superuser and CWR. I found a reference to a flashable stock recovery in post 14 here http://forum.xda-developers.com/showthread.php?t=1205639&page=2 , but I'm unclear on the instructions.
I'm trying to understand how, if possible, to return my VZW LTE Tab to out-of-the-box stock, if desired.
Rooted: Droid Incredible / Droid X / Thunderbolt / 3G-4G Xoom / Galaxy Tab 10.1 LTE
I have the Superuser icon showing up in my apps folder, but I don't appear to have root access. I can't su in the terminal emulator nor can I load apps that require root access. I also tried removing the Superuser.apk via a file manager with no luck.
Any idea how to remove this thing if I don't actually have root access?

OK, I rooted again and fixed whatever was broken. Then I was able to apply these commands to unroot the device.
Thank you!

Stock Recovery isn't required to Root the device. However, if you wish to install CWM via ROM Manager from the Android Market, Root Permissions are required.
If you use an ODIN Flash of CWM, there is no need for Root Permissions because you are flashing via ODIN.
The stock recovery zip file that you referenced in the other post should be fine.
Just use ODIN to Flash back to Stock Recovery and use the process that I mentioned to remove Root Permissions and Super User, and you should be all set to return your device after a Factory Wipe.
Cheers!

Scott,
I'm sorry for just seeing your post. I'm sure that you figured it out by now. You need to gain Root Access to your device again to remove Super User. You are in a Catch22.
If you are using an SCH-I905, Root your device, then download Script Manager from the Android Market.
Run this very simple Bash Script that I wrote to remove Root and Super User.
Paste this into notepad and save it as Unroot.sh then run with Script Manager.
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/app
rm Superuser.apk
cd /system/bin
rm su
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
Be sure to run the Script as Root from within Script Manager. The app will kind of freeze up as soon as it runs, which is normal. This will certainly take care of your problem.
Thanks for your post of stockrec in a different post. You saved me a month ago with that one.
Cheers!
Will Samsung know if I rooted my GT 10.1 LTE after using these commands, and sending in for warranty?
Does anyone know how often airwatch checks for the root? anyway to bypass the checks?
Is this the same for the US Cellular 4G Tablet? I have been reading and all that I have found was WiFi only files. Which if I were to root with those I lose the 4G radio.
Perfect.. Just what I need. Thanks
Ive been googling on the intranet machine for awhile now and cant find out how to get the binary for this or just zipalign my apks another way. I am using ROM toolbox pro.

Download it and put it in /system/xbin. Then chmod it to 755. IF you need steps on how to do this, let me know.
http://dl.dropbox.com/u/34706306/zipalign
Yea I do. Im not sure what chmod it to 755 means. I know how to dl it n put it in the /system/xbin. Anywhere in there Im guessing.
Will this run the whole thing? Or is this just the binary for it? Would I still use ROM Toolbox run zipalign? THANKS a lot Ive been trying to find a fix for awhile.
Quick explanation:
Open a terminal emulator, navigate to /system/xbin with the "cd" command, and type "chmod 755 whateverthefileis". That'll change the permissions. If you want an explanation of what you're actually doing, you can read below. It's not necessary if you're not interested though.
If you're curious:
I guess I'll attempt briefly explaining the chmod command and Linux (Unix, Android, etc) permission notation. What do you want the file's permissions to be? In Linux, a file has an owner (who is the most intimately tied to the file), a group (which allows you to assign fewer privileges than the owner, but more control than default) and other (which means anyone not specified by the previous 2 conditions). For each of these groups, you can assign read, write, and execute permissions. These are written as rwx triplets. The notation "rwx" means full read, write, and execute permissions to whatever category of user that triplet is referring to. If you want to deny one of those permissions, replace the letter by the "-" placeholder. So "r-x" would mean that category of users wouldn't have write permissions. Files have these permissions listed in rwx triplets for the owner first, then the group, then others and are lead by what will usually be an initial "-" placeholder. So a file with permissions listed as "-rwxrw-r--" has an initial "-" placeholder like usual, followed by full rwx permissions for the owner, read and write permissions for the group, and read permissions for everyone else. You can view the permissions of any file by opening a terminal emulator, navigating to the directory where it is located and typing "ls -l" which will list details about each file in the directory, including permissions.
The chmod command in the form that was mentioned above, condenses the triplet describing the permissions for each group into a single number. It does this by treating permissible operations in each triplet as a 1, and operations that are denied as a 0. So if the owner's permissions are described as "rw-", this would translate into "110". This number is then read as binary and converted to decimal. 110 in binary equals 6 in decimal. So what "chmod 755 whateverfile" means is change the permissions of whateverfile to allow the owner full rwx permissions, allow members of the group the file belongs to read and execute permissions. And allow everyone else read and execute permissions as well. So "755" means "111|101|101" if you expand those back to the binary. And if we replace each 1 with the number it is representing, it will look like "rwxr-xr-x".

I probably should check the threads I post assistance to a little more often. Thanks for responding.
I cant put the file into my /system/xbin. It says error permission denied or something like that. I cant save it straight to there either.
Type "su" and then hit Enter. When the box comes up for allowing privileges, allow them. Now try again.

Alternative can be copy app into your custom rom then flash the rom .

If it's just a launcher why not try installing it as a user app then try converting to system app with Titanium

Enable all toggles + unlock native Tethering
If you have Safestrap installed and are on a MK2 or MJ7 rom/build you can flash the corresponding zip below and you will unlock native built-in tethering and also get all the toggles including the usually absent Wifi Hotspot toggle. Both versions have been tested and confirmed to be work. This also enables all the missing toggles, not only the Wifi Hotspot toggle. Toggle issue = solved. If you don't have Safestrap then let me know, I'll write up a script to do the same thing if needed.
@Scottchy014 made an awesome video of the process that you can watch here
Devs/Modders/Themers - You can use my script without my permission and you don't need to give me credit. I don't do this for ego/pride I'm already narcissistic enough as it is.

Please read the instructions; accidents while flashing framework-res.apk can and do happen and those mistakes lead to having to use full Odin restore tars. I almost made open1your1eyes0 brick had he not caught my mistake in the code. Luckily he was nice enough to test again, luckily that one worked
Instructions:
(Try the alternate method below first, it seems to work with less errors, but if you insist on using the script then FOR MK2 replace all instances of "MJ7" below with "MK2")
1. Extract MJ7_tether_unlock.zip and move the MJ7_tether_unlock folder to the root
of your micro sdcard so the structure looks like this: /mnt/extSdCard/MJ7_tether_unlock/
also make sure you have busybox installed and are using SuperSu and not the chinese superuser.
Finally, before continuing, remember to disable the Knox apps (5 I believe?) and security apps (the 4 VZW security apps) install busybox, remove the Chinese superuser, update SuperSu's binaries, enable usb debugging and under security disable verify apps while enabling unknown sources.
2. Download terminal emulator then type the following in terminal:
Code:
su
cd /mnt/extSdCard/MJ7_tether_unlock/
sh tether.sh
3. After that your phone should reboot, and tethering should be unlocked! Also a copy of your original framework-res.apk
can be found in the following directory /mnt/extSdCard/MJ7_tether_unlock/orig-framework-res.apk
4. To restore back to your original framework-res.Code:apk, (i.e, relock tethering) then type the following in terminal:
Code:
su
cd /mnt/extSdCard/MJ7_tether_unlock/
sh untether.sh

Alternate link: Mirror

MK2
Download the zip here
MD5: ed0e0f974d7d8720690b8eb96461b5f3
To download just the modded MK2 framework-res.apk click here
ALTERNATE METHOD
DO NOT RENAME the original framework-res.apk file! You will have to use an Odin tar to recover!
1.Download the modded framework-res.apk from here for MJ7 or here for MK2 then copy it to /system first then change framework-res.apk's permissions to rw-r--r-- (chmod 644) and then MOVE it to /system/framework and overwrite framework-res.apk. Then reboot and you should have tethering!
Simply copy and pasting will cause you to boot loop so instead move it to /system first and change the permissions then and only then move it to /system/framework/ and overwrite the original

Was a stupid question. Just saw the first command in TE was to type SU. Guess I'll root this junk. Been putting it off forever since I didn't want to flash a ROM and tethering worked.
confirmed
I have gs4 Verizon running MJ7 4.3 and used this to unlock my tethering capability.
Thank you for this information and your work!
I have unlimited data plan and was stuck using WiFi router which burned up battery like crazy. This is so much better now.
Thanks again! :good:

So I saw this portion of the thread and thought I would try to achieve this also. I messed with the system folder and totally bricked my phone. No hope of recovery. It was my fault for messing with something that I knew nothing about but just want to caution anyone thinking of doing this to be very careful.
I changed permissions for this folder and locked up the phone and it won't even let me Odin, flash through recovery or sideload through adb.
So my device is toast.
Just be wary of messing with things unfamiliar.

Sorry I changed the directions because I could have been more clear. You messed with the system folder? I was saying to make the system r/w and chmod 644 the file feature.xml under /system/csc/. The system folder it self should be chmod 755, but you dont chmod the system to anything, leave the system folder alone in fact never change the permissions of /system or any folder within the /system directory, only change it on files within a folder. For example /system and /system/csc should both be rwxr-xr-x (755) and never changed, while /system/csc/feature.xml should have its permissions set to rw-r--r-- (644) What do you mean you cant Odin what happens when you try?
what's chmod 644?? I've been around a while but I never heard that before?

When people say"push the app to /system and then change permissions" the permissions they are referring to is setting chmod the app to 644 which is setting the permissions for the owner, group and others.
chmod 644 = rw-r--r--
Owners -6 = read and write
Group - 4 = read only
Others -4 = read only
Number convention:
4 = read only
2 = write only
4 + 2 = 6
6 = read and write
5 = read and execute
5+2 =7
7= read, write and execute

That's the UNIX "change mode" command. That's the way that UNIX systems define the protection mode for files.
644 is a protection mode, meaning read/write for owner (6), read for group (4), read for all (4).
Your root file manager should be able to allow you to set the mode and ownership of any file that you copy around.

The system folder it self should be chmod 755, but you dont chmod the system to anything, leave the system folder alone in fact never change the permissions of /system or any folder within the /system directory, only change it on files within a folder. For example /system and /system/csc should both be rwxr-xr-x (755) and never changed, while /system/csc/feature.xml should have its permissions set to rw-r--r-- (644) What do you mean you cant Odin what happens when you try?

I am certainly not blaming anyone for this, it was clearly my fault for messing where I shouldn't be but I appreciate you wanting to help.
After I changed the system folder permissions, it immediately crashed. When it rebooted it bootlooped twice then booted into system recovery where the android guy lay on his back dead with a red exclamation point in his belly. It simply said error and nothing else but gave options to update, reboot, wipe, the usual.
I tried every file to be had that I could download for Odin, or recovery update. Odin simply failed every time. Recovery update always said signature match fail on every rom file. I must have tried 6 different rom files including one that is claimed to be the ME7 newest update untouched.
All methods completely failed.
I have rooted for years, installed countless ROM files on all my phones and this is the first I have bricked. I am not anything more than a reader that follow directions when it comes to this stuff, but have always been able to fix any problems until this one.
I have read threads on unbricking until I am sick of reading and trying. I guess its time to throw in the towel.
Thanks for updating the directions so nobody else does the stupid that I did.

Did you try to use adb at all? Where does odin fail at? You can try three suggestions I have, but first install android-sdk tools and make sure adb is working.
1. Connect your phone to your pc via usb and run the attached adb_system_fix.bat file found in the the Samsung_Tools folder ive uploaded here while your phone is attempting to boot.
2. Boot to recovery and try the to use adb/ab sideload there and enter the following
Code:
adb shell su -c "mount -o remount rw /system"
adb shell chmod 755 /system
3.(last resort, try any other suggestion first!)
Download the VRUEMJ7 stock odin tar from here and extract the .pit file from within (temporarily rename the tar.md5 to tar to extract) then boot to download mode and open Odin 3.09 and select the pit file in the pit slot (also check repartition) and the odin tar in AP. Hit start

Can you give me some direction on how to perform the adb operation. I am able to boot to recovery, I have adb installed and know how to access it from CMD window. But not sure how to send commands to phone.
Can you help a little more?
I tried method 1 but it did nothing. What I did was starting the bat file and then booted phone. It just kept buzzing over and over like a fast bootloop.
Going to try method 2 but a little lost.
Please help a little more?
Thanks

Well as expected it failed. Anything I type in and enter I get "error: closed"
It is a lost cause I am afraid.
I am considering method 3 and can follow most of the instructions, but the last instruction is where I lose you. It says "..and the Odin file in the AP". is that supposed to be PDA?
After this I wont bug you anymore since it is obviously a lost cause.
Thanks for everything.

Alright I sent you a pm
Will this trigger any part of verizons security? will the system know if something was flashed?
can someone explain how to use bypasslkm in further detail. i looked through multiple threads but im stilll not getting the handle on it,
Open your terminal emulator on your phone (download one from Google play if you don't have one) open the terminal and type the following commands (Pressing enter to execute each one)
su (sands for switch user, used alone will switch you to the "root" user. Equilivent to Admin in windows)
cd /data/local/temp (cd - change directory, followed by the complete folder path you want to navigate to)
chmod 755 bypasslkm (not going to get too in depth with this one because I could go on for a while with it but "chmod 755" changes the permissions to read, write, execute for the root user and read/execute for everyone else)
. /bypasslkm (. / tells the system to look in the current directory and, in this case, execute bypasslkm)
Hope this helps clear some things up for you!

I had the same issue. Here is the binary from Surges dropbox https://www.dropbox.com/s/9rdz9ff6x5foech/bypasslkm
Make sure you copy it to the right directory and follow all the commands.

Thats not an error. If you had bypasslkm anywhere on your phone, it should now be in /data/local/tmp with the right permissions and should have executed. Make sure you downloaded the bypasslkm binary linked above
Edit: Also just copy and paste the whole script to make things easier

The permissions should be 755, as Surge said.
If you KNOW it's in /data/local/tmp, then do this in a terminal emulator window:
Code:
su
mount -o remount,rw /system
chmod 755 /data/local/tmp/bypasslkm
/data/local/tmp/bypasslkm
insmod /system/lib/modules/dhd.ko
mount -o remount,ro /system
exit
If this doesn't work, DO NOT post just "it didn't work". Say what you did, why you think it failed. Capture the output and reply here with it.

I figured it out! Here is exactly what I did:
after downloading the bypasslkm.bin from the dropbox link, I used ES File Explorer (WITH ROOT ENABLED) to move the bypasslkm file to directly to the data/local/tmp location. NOTE: there are a few places marked "data" and "local" on the phone, so when you open a "data" folder, make sure you find the path in the right order [ i.e. first data, then local, and then tmp]
Using a ROOT FILE EXPLORER app (because ES doesn't have what you will need) go to the bypasslkm file, long press, and select permissions. It will display with permissions are currently set. At the bottom, it SHOULD display the total sum of the permissions selected. Basically, that means by selecting the right boxes, you can change the permissions to 755 !
7 5 5
user group world
r+w+x r+x r+x
4+2+1 4+0+1 4+0+1 = 755
These setting will give you the 755 that you need to pull this off .
When you have the permissions changed to 755, the last step was actually very easy. But if you want to play it safe, then I will tell you the root file browser I specifically used to do the last step.
I used the app Root Browser version 2.2.3 ( i literally googled for any generic root file explorer and this came up )
ok, so when you have the permissions changed, long press on the bypasslkm file.
select "Open With" and then select the option "Open As.."
At the bottom of the options is "script file" select it.
after doing so, select the option "Execute" and... Voila! I immediately regained my WIFI !!!!! \>w</
I hope this guide helped everyone out. I tried to be as specific as possible.

Thanks for the support. Glad I could help. Has your WIFI remained on, though? The solution I posted works, but only for a short amount of time. rebooting the system undoes the work I did and I have to go back into the root browser and execute the file all over again to get wifi.
Can Surge or someone else offer any expertise?
with the permissions changed properly, I tried executing the code, and still not working.
I have safestrap enabled, and I have sound restored. I am currently on android 4.3 from the downgrade provided by Surge. Its rooted.
If I were to upgrade to the rooted version of NC5, would that help fix the wifi issue, or would it carry over?
Any input going forward is appreciated!

It is possible to automate this.
Create a file with the following contents:
Code:
#!/system/bin/sh
/data/local/tmp/bypasslkm
insmod /system/lib/modules/dhd.ko
exit
Save this file as /system/etc/install-recovery-2.sh.
Make sure that the bypasslkm file is in /data/local/tmp.
Reboot, and you should now have WiFi again.
[Note: this assumes SuperSU has it's custom copy of /system/etc/install-recovery.sh in place. If that's not there, it's still possible to edit /init.rc to add a stanza to run this command.]

Ok, so I figured out the coding a little bit. Im not used to this, so forgive my ignorance.
I did the code as u typed it. BUT I made a change. Because I kept getting the "file not found " error. I added ".bin" to the end of the bypasslkm code line. It generated a real response. I felt relieved. I went ahead and typed the last line of code.
THEN I was told the file already exists... I have attached a picture of what I got in android Terminal

You should have /system/etc/install-recovery.sh
It will run /system/etc/install-recovery-2.sh if it exists. What I would do is to create the file on your PC, put it onto your SDcard on the PC, then use Root Explorer to put it into place.
The "file exists" error is because you already have the WiFi module installed. That won't happen when this script runs at boot.

Ok. I'll try that tonight.
But I have a few questions
Im basically trying to autostart the wifi module when the phone boots up right? Are there any apps that can accomplish this specific task?
Also about the downgrade in general. Did anyone get their SD card permissions restored after downgrading? I donwgraded to 4.3, rooted the phone, and somehow I STILL cant move apps to the sd card! Im beginning to suspect that thr issue may be with the card itself, which can be fixed with formatting the sd card. But has anyone had any problems with moving apps to the sd card?
Finally, the bug question concerning the wifi issue.
Is this probkem specific only to those with the downgrade? If so, should upgrading to Surge's rooted kitkat (with sd card permissions and tethered enabled) resolve the wifi issue?
I also noticed that I had wifi access when the phone had no sound. Only when I flashed the Non-HLOS bin file did I encounter this wifi issue.
Thanks for the feedback so far, I just need to understand whrre to go from here

I'm sure there are programs that can be set up to run scripts as root during boot; However, that's complicated since you want this to run while the phone is booting, before there's any opportunity to allow SuperSU to ask for permission.

That's a problem that's fixed by an edit to /system/etc/permissions/platform.xml, adding a stanza that permits external storage write access.

The need to run the "bypasslkm" program is because of the downgrade. If you go to a clean rooted Kit Kat ROM, it shouldn't have any issues with WiFi being enabled. That may be the easiest way to fix this.
