Lost Root - Galaxy Note II Q&A, Help & Troubleshooting

Hello friends
I am using the N7100. I flashed the CM12 Unofficial Build and was extremely happy with it. I recently updated it to the 05.01.14 build and found out I had lost all root privileges. I do not understand how that happened considering I was rooted all along till flashing that update. I would like to know what I should do now to get back root.
Thank you so much.

I believe that root is disabled by default in CM12. Go to the Developer Settings and find Root Access. Click on it and select Apps Only.
If it doesn't work, download SuperSU and flash it via ur recovery.

Very interesting what you are describing since I do not have this issue with cm10.2 but good to know.

SlimROM's come with root, but you need to change the configuration permissions for only apps (default is apps+adb), and problem solved. Don't need to install any other root apps.
By the way, the super user configurations can be found in settings.

APK root exploit

I tweeted this a couple week ago before the N1 was publicly out but here you go, nothing fancy, no real ui or output.
Thanks to Saurik and Giantpune for contributing (ie its based on their research)
Install apk, run apk wait 1 minute, install supersu app from market then uninstall with this command
adb uninstall com.qualcomm.privinit
Do you have a link to their research or are their findings private?

Will this exploit work in any other device. when i try to install the play store warns about the vulnerability. Will this vulnerability be gone after uninstalling oppoown.

It should be patched in 4.4.
But some (read most) OEMs still can't manage to patch their devices up to the latest security updates on release.
Anyway, I tested this root method a week or so ago and it works nicely

so your saying in most devices the master key patch could be a possible vulnurabillity still in 4.3?

It depends on if OEMs backported it, depends on which build OEMs used and depends on the bug. Four or five different zip parser bugs with similar results. This one I used was patched in 4.3, but other exist.
Im trying to figure out why oppown apk will not install in my n1. everytime i try it just. Says app not installed. But on the install screen it says something about being an update to an already installed program. Any clues as to what the issue is? all ive done is update to the latest ota software and im currently located in indonesia if that makes a difference.

It should not come rooted, if it comes rooted then no way did it pass CTS. I'm guessing unlocking the bootloader and flashing a recovery? I don't know, I dont have one

You don't need to root if you aren't staying on stock. There's no lock anywhere on the bootloader or anything.
Simply flash TWRP in fastboot, then flash Omni (or whatever else) through TWRP.
You should be able to just flash a SuperSU zip in TWRP as well if you want to root the stock ColorOS.

4) reboot recovery wipe cache and dalvik flash omnirom..
Please correct me..
Thank you
giuliano rigon said:
1) download twrp Yes
2) put it in root of the telephone Yes
Make sure to copy Omnirom to your phone at some point
3) flash it in recovery? No - Flash TWRP in Fastboot if you haven't flashed the recovery already. Use the official Teamwin site for guidance
4) reboot recovery wipe cache and dalvik flash omnirom.. Wipe Cache, Dalvik, System, and Data

This is off-topic for this thread though. Questions/Info for flashing Omnirom should be addressed in the Omnirom thread.

That does work. You're likely not removing root, but rather just uninstalling SuperSU.

4.4. KitKat for Wifi Note 10.1 2014 P600 Q&A

Hi guys I have some questions about the new Firmware and KitKat in general and you may have answers I'll try to update first post with your answers!
-Will I loose root when I flash through Odin? --> Yes
-Is the new firmware rootable, or is there a way to keep root when I upgrade from rooted 4.3?
-->For upgrade yes: If you are rooted on 4.3 you can restore root by flashing a custom recovery and flash superSU manually.
-->chainfire autoroot works but you need to update the superSU app through play store after flashing.
-Will KitKat restrict access to my SD card? -->Yes but fixable through an app or editing a file (needs root), there is already a thread about that.
-Can I still use flash with KitKat? How?
-->Yes, there is a hacked version see 2nd post for link.
-How is the touchscreen driver? Is the stuttering fixed? Do touch and hold actions still drop after ~23sec?
-->Pretty much fixed. To about the same state as the improved Kernel we had a while ago.
-Are there any apps that are not working (root apps too)?
-Gesture Controls? --> works
-Xposed framework app settings? -->works
-Is Hancom Office included or does it still work? --> not included but does still work.
Thats about what I can think of a the moment.
Hi,
If you are already rooted then all you have to do is re install TWRP and then flash SU zip then you have root.
For flash player, download hacked version here, it works I tested it on new software :
http://forum.xda-developers.com/go...e-how-to-play-flash-video-android-4-t2548001
Also, xposed works. Tested it on new software

Chainfire's Auto Root does work, once you flash it thru odin and reboot, go to the Play store and update the app.
- Please update OP
Here's a question: I'm already rooted. Is flashing the stock KitKat image via Odin and rerooting the only way to upgrade?

If you are already rooted, I assume you have TWRP too. Just download this KitKat rom, full wipe and install.

Not for me I flashed a stock 4.4 kit kat on my tablet coming from root 4.3. I then flashed chainfire autoroot thru odin on the 4.4 and the superuser there only problem is it displays this ' There is no SU binary installed, and SuperSU cannot install this is a problem! I formatted my 4.3 before flashing it maybe thats why?

Not sure... I installed KK on the tablet via Odin, then rebooted and setup, then rebooted into download mode and flashed auto root thru Odin.
Upon reboot I got an error selecting SuperSU, but once I updated it thru the Play Store its been fine.
Using ES Explorer I removed the items I don't need and removed all of the Knox stuff.
There are a few of us this worked for so I don't know what went wrong for you.
If you don't succeed then try again, and again, and again....Good luck.

Thx for the response from what i can see you never fully wipe your data before installing 4.4 KK but i did so i believe i lost my root like that. So when i updated the supersu never carried over from 4.3

It's exactly the same as before.
Look for how do I root here,
http://forum.xda-developers.com/showthread.php?t=2711073
You unlock bootloader. Flash a custom recovery... I suggest twrp. It will ask you when you exit if you want to root. Say yes.
Boot into android, install supersu if it or superuser aren't there already. (from play store)
Or just flash recovery . Install a rom , likely rooted already.

Can you explain everything you did, beginning to end. And exactly when/where you get that message?
I had already TWRP in my phone so I download your files. Opened the recovery and I did from there (install). When it finished rebooted the device and after that when i did a root check it said root access not properly install or sometihing

Open the SuperSU app, and it will prompt you to install the binaries. Select yes, of course.

If it asks to update with a "normal" and "twrp/cwm" option... Try normal first. The other option if that doesn't work.

I tried the normal it didnt work, how I do the second, I pressed it but nothing happened!
I don't think you have twrp installed anymore, or not properly. You've flashed it with fastboot, since updating to lollipop? How did you update to lollipop?
Normal, I never had root before. Upgraded my phone to 5.0 and then i tried to root it
Rooted fine here with normal method. Just had to update super su.
OK, can you please walk us through exactly what steps to Root you took. From the beginning. And we'll see what happened.

Made a full root-uninstall on CM12.1 - how to properly re-root?

After successfully flashing CM12.1 and playing around with it a little bit, I wanted to completely remove root (to get a few apps running). So I was advised to download SuperSU and use it to make a full/complete root removal. After that I de-installed SuperSU and disabled root in the Developer Options.
Well, that worked, I could run the apps that were unhappy with just root disabled in Developer Options. But now I want to have root back and I read in a couple of place that just flashing the latest SuperSU.zip from recovery might be a bad idea.
Any suggestions how to properly re-root my CM12.1 ?
