[Q] How to I uninstall/remove Superuser.apk or Unroot

keplenk · Feb 25, 2012

Hi all,

I just did a System Level root here http://xdaforums.com/showthread.php?t=1505062 and it was successful. It didn't add flash counters which is why I chose this method.

I was able to install Superuser and Titanium Backup.

However I need to return the phone for exchange because this one is currently defective (charger issues).

Now I'm trying to unroot and restore to defaults. First I uninstall Titanium backup which was easy. Then now I can't UNinstall Superuser.apk. I look for guides and found that I need to download Terminal Emulator, enable root then run these commands:

Code:

su
rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su

However, when I run this it gives me this error:

Code:

#rm -r /system app Superuser.apk
rm failed for Superuser.apk, Read-only file system

So yeah, it won't delete and I can't return it with Superuser installed in there

Is there a different method to just download the official restore .tar file from Samsung and just restore it that way using odin. If there is, where can I find that .tar file?

Please help, I only have a few hours before I can return this

Thanks!

Just an update (I'll just reply to myself since I found a solution)

I was able to delete the Superuser.apk,busybox,su by following this guide: http://xdaforums.com/showpost.php?p=7386761&postcount=2

Code:

su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/app
rm Superuser.apk
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system

However my device is still rooted. Although Bestbuy/AT&T might not detect it, Samsung probably will .. so warranty can still be voided.

Anyway, is there way to unroot easily?

I'm guessing that using the official .tar file from samsung ... will fix this.

Where can I find that file?

THanks again!

How is Samsung going to link your Best Buy return back to you? Since you are within 30 days, your return will be fine. I think the concern is the flash counter when sending in for warranty repairs after the 30 day return window.

Thanks! Point taken. But yup .. I guess I was talking about future issues when I will have to deal with Samsung (hopefully not).

So .. is there a restore .tar file that samsung provides?

Thanks again.

Not sure if it will work but i would assume just flashing the stock att tar would remove root

Or just do a reset under settings>Privacy.

will that actually "unroot" it?

No. 2 ways to unroot. Remount r/w, and remove said binaries, or flash system.img with stock the same way you flashed the rooted system.img.

do you have a link for a real/safe ATT stock system.img we can flash?

There is a stock system here. I'm pretty sure since it is the stock signed kernal it shouldn't trip the counter either. Maybe someone with an already tripped counter can try it and report.

Another way to return to stock is with Kies. I have used this method a couple of times with no problems. Once Kies wouldn't recognize my note, so I had to flash a stock ics rom from the super everything thread, then hook it up so kies would recognize. There is also a flash counter reset in the super everything if you are worried about that.

Did you get the insurance from Best Buy? Or just worried about warranty from Samsung? If you have BB insurance, just run over the thing with your car before taking it back. That's what I plan to do. Just before my contract is up I always return for a new phone. They can't check the flash counter if it is snapped in half

I will say a simple method to uninstall superuser.

First you root your phone again

Download clean master which is free.
Now open it. And allow superuser permission. Now open app manager.
It shows uninstall-backup -move options.
Select pre installed apps . Click superuser and click uninstall.

Hurray u have uninstalled superuser . My what's app number 7401660083. Message me I you have any doubt:good:
