[ROOT] Stock ICS Leak One-Click Root Tool

Hi all!
First off, I'm new to xda Developers so please excuse me if this is in the wrong forum! I thought I'd post information about a tool I wrote here which roots stock 4.0.3 leak on the A500, A501 and assumingly the A200 too. Its literally one click - just enable USB debugging. "ICS Root" also installs, optionally, FaceLock and Trebuchet (although FaceLock doesn't want to work. It lets you set it up though =P)
Since version 5.0.1 this also now works with the new 0.022.00 leak!
The full post is over at TegraOwners: http://forum.tegraowners.com/viewtopic.php?f=30&t=350
The only real system requirements are Windows (with .Net Framework 4) and an Iconia on the stock 4.0.3 leak. I hope somebody finds this useful its been tested by myself and a couple of TegraOwners users and it works well.
In terms of the technique used, it uses the great Jay Freeman's mempodroid exploit to gain root at which point it mounts /system rw and installs su, busybox and Superuser.apk so no real surprises there. Installing Trebuchet adds that apk to /system/app and installing FaceLock installs the apk to /system/app before installing the pittpatt folder to the flexrom (mounted as /system/vendor). I plan to open source it when all the requested features have been implemented and the code has been cleaned up.
Thanks!

cwm version?
why would it not work with cwm version?

With this tool does system remain writeable after rooting?

What about flashing CWM with acer recovery installer once rooted? I guess it would screw the bootloader...

If you are on the cwm with the HC boot loader it should work as Its Magic will be run..
if you are on the new boot loader as in the full non modded leak.. It will give you secure boot error ..
The new boot loader Blocks its magic.

Thanks
Hey this worked easy. I had to re-install USB drivers and make sure I had the latest from Google. Other then that, hit the button, wait about 1.5 minutes, and it rebooted! No problems thus far! Thanks Again!

root doesnt work like its supposed to. i know its only half root due to the bootloader, but terminal emulator flat out says i'm not rooted after this despite sixasis working and titanium backup/root checker both saying i have root and busybox. i'm going to post this on TO as well for you incase you dont check here often.

That's storage cos terminal works for me and running su in an adb shell works great too.

After reading the other post, I have found that I cannot write to the system directory from the device itself. The folder attributes indicate that it is set to write, however File Explorer HD will not let me. I have tried to create a folder in the /system and it will not accept the addition. The strange thing is that Root Check says it is rooted, File Explorer HD accepts putting it into Root Explore, but that is it. It is odd. I will try to reapply the Root to see if that makes a difference.

Please, read the op before bringing this up. This method is for half root, its the only way possible right now on stock leak ics. There is a special script you need to use to mpunt system. You can find it in the stock leak thread, run it in terminal or use rom toolbox and set it as a script to run at boot because rebooting loses write privileges.

Version 3 came out this morning
It features some bug fixes as well as a completely new remount menu which mounts /system rw properly on the fly. Tested with a busybox installer app
Enjoy!

Thanks for your tool blackthund3r !
I tried it with the new leak from this morning and it doesn't seem to work anymore
Edit :
Just to be a little more specific, the app says the process was OK and state that the tablet is rooted but the tablet doesn't reboot by itseld and su is not installed. I tried to install su manually but it's unable to find a previous su package on the system.

ah okay it appears a completely new leak has been released. It is possible that the mempodroid exploit has been patched up. I'm gonna look into it soon. I can't much tonight - I have school work. I'll see what can be done and what the differences between leaks are.

Hi blackthund3r
Thanks for the update 3.1 but could you please fix the problem on your hosting website? clicking on this file send to an error warning.
The other files can be downloaded though.

can someone post a mirror to the 3.1 version? current link is not working.
can somebody also confirm, if i root with this tool, i will be able to reinstall my clockworkmod recovery through 'acer recovery installer' and flash any other cwm rom? or do i have to downgrade to honeycomb 3.01, install iconiaroot for honeycomb and then acer recovery installer?

Gersma,
I'll be able to answer to your question as soon as I'll be able to download this tool and test it.

Install CWM 5.5.0.4

Hi guys!
I've been in a struggle trying to install CWM 5.5.0.4 on my IDEOS X5.
Currently my phone's rooted and with U8800V100R001C00B518G001(Beta1.0)(Overseas Normal)(Gingerbread).
-> I tried to do it by the pink screen but i can't access the desired folder.
->I tried to do it with Remount (even tho it only shows /.cust_backup and no /image then) and i get "Failure! /.cust_backup could not be remounted as RW"
->I tried with Root explorer and everytime i click on "Mount R/W" it does nothing, so i can't copy/paste
Can't remember what i've done more...
Can i get some help plz? Ty

you are sure it is rooted?
can you change r/w on other systen directories in root explorer?

If you don't have superuser icon after root, it isn't rooted, something went wrong with the rooting process... try rooting again, search the forum for the root method for your specific stock ROM version...

[HELP] How to ROOT multi user

Hello
Firstly sorry for my english
I'll tried to explain my problem
I successfull to root my device but only the main user account but I can't obtain access root in others account.
How can I do this ?
Thanks

At the moment you can't until Google updates that feature to allow that. The multiuser is in its infancy. We will just have to wait I guess.
Sent from my Nexus 10 using Tapatalk HD

Thanks for your answer
waiting for this ...

It's actually the su binary which is tied to the primary user only at the moment... not sure how, or if, it can be built otherwise!

Furthermore, it is not even possible to enable developer settings (via build no) for second users, right?
So, without USB-Debugging no adb to backup second user apps (w/ data) using the Toolkit..
Is there any chance to fully backup second user apps? Apart from nand of course, as I would like to backup/restore apps for a switch to CM10.

Superuser 3.3 now supports multi-user root... 3 modes... Owner only, Owner controlled & User controlled... I will post an update zip here once I built su & Superuser tonight!

Nope... not my mod... official updates to Superuser... I've just built it with the new changes!!
Here you go... Superuser-3.3-arm.zip
Notable Changes (from Superuser 3.2):
1. Android 4.2+ multi-user support [3 mode -> Owner only, Owner controlled & User controlled]
2. Better handling of applications with multiple root (su) requests
Flashing using a custom recovery (TWRP or CWM). I recommend wiping data for the Superuser app and re-granting your root apps su access to avoid any problems.
NOTE: Even though Superuser 3.3 supports multiple users, you root apps may not... so there is no guarantee that all root apps will work fine in multi-user mode. For those app, you will need to wait for the app developers to update their apps to support multiple users.

If you are using SuperSu, the dialog asking for root permission shows up on the owner's user account. In SuperSu, only the owner can grant superuser privileges.

For android phones and tablets, there's arm, mips, and x86. Any good android will 98% likely be arm. Motorola released an x86 (Intel) phone, and I'm sure there's a few other ones out there. And if you have mips, you probably got a cheapy Chinese tablet. xP

Sorry for hijacking.
My main reason for root is to restore application data. Will I be able to restore the data on both the primary user and also the secondary user if I have root (either through the main or secondary user)

Did i do something wrong?
I had supersu installt- and need multiuser acsess . So i install Superuser in recovery with the zipfile .
But now no root app will work- with no user.:crying:
notice main user by starting: sorry i cant get root.... this was a try by /system/bin/su .
2 notice by superuser -on screen and in the log: superuser rights of ..app... are denied.
What do i do now ?

It sounds like the zips don't play very well together.
Boot into recovery.
Mount /system
Delete /system/app/Superuser.apk
Delete /system/bin/su (if it exists)
Delete /system/xbin/su (if it exists)
Clear the Dalvik cache to err on the safe side.
You should now be unrooted. (In fact you could boot up, and you should see there is no superuser app installed)
Now, just flash the superuser zip again to root your device.

It sounds like you have Superuser 3.3 installed and working, right? In order to use Superuser 3.3 with another user account, you need to go to its preferences and change Multi-user Mode to something other than "Owner Only."
"Owner only" means that only the owner can su.
"Owner controlled" means that the owner is the only one who can set and deny root permissions. Any filters are applied to all users.
"User controlled" means that each user can define allow/deny filters. Only use this option if you really trust other users.
Don't update to the version of Superuser on the Play Store. The version on the Play Store is 3.1.3. You already have 3.3 flashed on your system partition. Because you won't need the version on the Play Store, you can also stay away from ChainsDD's Superuser Update Fixer. (The update fixer is for an entirely different issue than the one you have.)
If you have installed these packages, you should uninstall them.
For future reference:
I should have been clearer about deleting files in custom recoveries. If you use TWRP, there is a built-in file manager under the Advanced menu. If you use ClockworkMod, you should use ADB commands: (ADB is a tool found in the Android SDK)
Code:
adb shell
cd /system
ls -al
[I](You should see a bunch of directories. If not, make sure /system is mounted.
This is an option in one of the recovery menus; I can't remember which
one offhand.)[/I]
rm app/Superuser.apk
rm bin/su
rm xbin/su
Then reflash the Superuser zip.

Don't suppose there's any way to fix this without a custom recovery is there?
I've rooted but can't mount/write to my System folder after doing a 4.4.4 OTA update, but I don't have a custom recovery installed. I just rooted using the toolkit and left it at that.

All of you who found that this ain't working, it is because you need to have correct busybox installed. After you have that it works as mentioned.

Basically Nougat made harder to write system partition. That zip applies a workaround making the default hosts file (/system/etc/hosts) a symlink to another host file in a writable mountpoint (/su/etc/hosts). You can find more info here https://github.com/AdAway/AdAway/issues/770.

It is the same issue as discussed here:
http://forum.xda-developers.com/nex...-to-unlock-tethering-nexus-5x-t3231301/page20
The workaround described above doesn't change /system (which would get error corrected back to original), but instead masks the file in /system with an alternate one during boot.

Thank you very much. It works like a charm.

Without this "trick" AdAway It doesn't show an error or fail... but it doesn't works. Try pinging any "supposed to be blocked" url. You may realized it's not blocked anymore.

Yes, this "trick" essentially writes the hosts file to another location, and creates a symlink to it. This way it doesn't need to write to the /system/ directory.
There is a one-line command you can run in terminal emulator that lets you write to /system, but you need to run it each time you reboot, and it's a bit of a nuisance to do so. This lets Adaway work each time without the necessity of a terminal command.

Just an FYI, if you install SuperSU you can write to system and it will stick. You wouldn't need to do anything each boot in that case.

That is a different problem than the one on stock Noguat then.
On stock without dm-verity disabled, the kernel will use forward error correction to "fix" you changes (ie data corruption) and replace with original. Basically you make the changes and they don't show up.

Nougat , flashed and no app installed, I downloaded adway from official website and working.

Link to original thread just for sure: http://forum.xda-developers.com/showthread.php?t=2190753

Please create Update for Android O.

AdAway works fine on O; no change from Nougat.
