Temp root for apps required root access (for s-on IS)

jrywu · Apr 17, 2011

Psneuter exploit is working on IS, but because /system is locked on s-on phones, we can't copy su and superuser.apk into /system, apps required root access can't work.
The following procedure uses psenuter exploit to gain adb shell root, and then copy su (without privilege control ) and busybox into /sbin (which is on rootfs and in the global PATH list) to gain root access for apps.
The procedure:
1. Unzip the attached .zip into a directory (like c:\adb)
2. Open a command prompt and cd to the directory where you extracted the .zip (like cd \adb)
3. run pushroot.bat (simply type pushroot)
4. adb shell /data/local/tmp/getroot
5. adb shell
6. you are now in # prompt. Type /data/local/tmp/pushroot

You have to redo steps 4,5,6 once you reboot your phone.

The procedure will have all apps gaining root access.
!!USE ON YOUR OWN RISK!!

Known working programs: Root explorer, Titanium backup, gscript lite, trasproxy 2.04, ...
Some apps check existence of su in /system/xbin , and reject to proceed if the su binary is not exist (like transproxy 3.08). For this kind of apps, this procedure won't help.

Good job...thanks

Thanks for writing this up, might quell the thirst for S-OFF a little longer

/system/ is writeable btw, if you remount it, but after reboot everything u done will be changed to the way it were before.

so a temp root in xbin is possible also, only it will be gone afterwards (atleast i never tried this, but should work also...)

jrywu · Apr 17, 2011

Yes. /system could be remount in rw with root. However, the files you wrote will be gone after you remount ro, and then you won't be able to copy the same filename into the same location again before next reboot ( I don't know why, actually!!). This is why I put su in sbin instead of /system/xbin.

Does anyone know whether steps 4, 5 and 6 can be run from the device itself?

Can I put these commands into some sort of script and run it everytime I need temp root or would I need to do this from a computer every time?

I believe you can do it from a terminal emulator but haven't got the chance to try it myself though.

Definitely, this is the way to go.
Unfortunately, the root exploit I know could run on device itself, including
rageagainstthecage (ratc) and local root exploit (hotplug) both failed on IS.

The solution will be nearly perfect if we can get temp root on IS without a computer link.
Any input will be welcome.

Please then type adb shell.
If you see # but not $, do
cd /data/local/tmp
rm ./cp
ln busybox cp
./pushroot
Then you finished the install.
If you see $, please do all over again.

You can also add ShootMe (screen capture app) and SetCPU to the list of working apps. SetCPU will only allow you underclock for now due to the kernel, but it is a nice touch if you are worried about battery life. Adfree doesn't appear to work

Adfree is working for me. Are you getting some type of error message?

MetaMorph, screenshot and MyBackup Root are also working.

I had to mount system, then push su to /system/xbin. Then install BusyBox Installer from Market.

No erro, still got the ads. I've tried rebooting & rerooting, still no luck

What site/app are you going to so I can see if I get the ads.

Hawkysoft · Apr 18, 2011

the anti-ads actually tries to modify the current host file... which is not allowed in your state as far as i know

what you can do is replace it by pushin it to the right spot
but after reboot gone,but sure u know

eddycyf · Apr 19, 2011

Adfee is working for me, you can also add Droidwall.

Hawkysoft · Apr 19, 2011

@eddycyf, did you test adfree with apps? Since it aint working for prophet...

Mhm AdFree isnt working for me. The App states that everything is okay, and that my hosts file is up to date, but I see ads everywhere.

But I am kinda happy now, because i can use Titanium Backup
