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

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.

As far as I know, there is no way to keep root if you get the OTA 4.3 update, right? I want to just get the OTA and not deal with the roms. Unlocked bootloader here...
According to Voodoo OTA Rootkeeper, it doesn't work with the 4.3 update: http://forum.xda-developers.com/showthread.php?t=1241517&page=6

If your bootloader is unlocked then it's easy... you just flash SuperSU in recovery after the update. No ROMs to deal with. On a Nexus device with an unlocked bootloader root is never an issue.

Not with stock recovery. But if you have an unlocked bootloader it's still no problem. You can boot to a custom recovery without even having to actually flash it if you want to keep stock recovery. So you just let the OTA install as normal then use fastboot to boot CWM or TWRP and flash SuperSU and you're done and rooted.
If your bootloader is unlocked, you might as well take advantage of it even if you want to remain mostly stock
Just keep in mind that SuperSU runs a daemon all the time can result in 70% cpu usage peaks. Don't blame 4.3 for it.

So is there a like guide on how to keep root when doing a system update? I have STOCK 4.2 Rooted and it is saying I should download an update. I do have TWRP installed. Is there another stock already rooted 4.3 I can download? Any help would be great so I dont have to factory reset.

Why even bother with this crap, flash the update, boot, flash custom recovery after and flash new SuperSU. You would be done before even typing this post.
I used the Nexus Root Toolkit by WugFresh to root my Galaxy Nexus on 4.3, and didn't lose any data...
All I did as usual was:-
1) Flash the update
2) Boot into TeamWin recovery (I keep the stock recovery installed)
3) Flash SuperSU 1.43
Simple, no issues.
If I have CMW Touch recovery can I install the OTA? I have received the notification but I don't know if I will be able to install it. Is there any way to revert back to Google's recovery just like installing a custom recovery? I mean not loosing data or having to so a factory reset.

How do you boot into twrp without flashing it? I know "fastboot flash recovery twrp.img" permanently overrides the built in recovery, but how would you boot into it just once?

Hi friendly xda android enthusiasts. I have, after many issues, finally rooted my gt-n5110 using odin and cf-auto. Workered without a hitch. Odin passed, tab rebooted, and BAM, "superSU has stopped working". I immediately navigated myself over to the playstore to reinstall SuperSU and for the first time i have ever seen it wouldnt allow me to. It only gave me a choice to open. No update no uninstall. Going into my apps list it was not present on downloads but was available on device list. Clucked it and no option to uninstall, only to force stop or turn off. So it is incorporated as a system with no access to it. This has me stumped. I have only seen old threads with answers to this and they are temp fixes. Need to know what i can do to fix this on a permanent basis and if someone could help me understand how and why this issue occured it would give me a better understanding and possibly prevent further issues. Thanks in advance guys.
Try the flashable version in this post after you install a custom recovery with odin.

This may be a very stupid question but i have to be sure. As i stated the odin DID pass the auto root and tab rebooted. But along with the superSU error i ran root checker and was unable to obtain root. Im assuming its because supersu is not embedded. So with that said is it still ok to attempt to flash a recovery to the tab?

Yes. Recovery is independent of whether or not you are rooted. You can install it from Android using tools like Flashify once you are properly rooted, but Odin works fine as long as you have a version of recovery in that format.
Flashing SuperSU from a custom recovery once it is installed should fix the superuser problems you are having.

Doing now. Thankyou. Fingers crossed.
I had the same issue on my 5110. The flashable root only worked for me until I rebooted, then it would lose root. What ultimately worked for me was to unroot with Kingo. Then with USB debugging enabled, re-rooted with Kingo (which took around 10 min).

If flashing SuperSU from recovery doesn't result in a successful rooted system someone should let @Chainfire know. I've never had a problem rooting a stock ROM that way but let's see what @mattdiehl83 reports.

Hi guys sorry for the delay in update. I ended up using VM ware and it allowed to operate as windows on OS X. I installed TWRP, went into the file manager in TWRP and removed the superSU, i then flashed superSU and rebooted. Once back to the tablet i went and restored services to superSU and went into the play store. And finally the playstore gave me the option the update the superSU. And then the rest was all normal installation of superSU. Hope this thread helps anybody dealing with these issues.
Glad you got it working. :good:

YOU DONT NEED TO DELETE SUPERSU 2.0.1
Install 2.02 apk and go to supersu, then to settings and push to /system
This is the easiest way. the one you found: go to recovery delete that and this. download supersu 2.0.2 apk and install it not the recovery zip i mean the APK! i didnt say the flashable supersu zip.
oh wait, yes you are a intelligent boy, you know everything.

That's a bit of a dilemma.
Unfortunately Samsung does not support using fastboot and bootloader mode (they call it download mode) so that standard SDK tool Google provides for Windows, Linux and MAC OS X isn't applicable. Your best bet would be to find a Windows PC that you can use to flash the recovery with Odin since that is the most common and best documented method.
Edit: NVM, somehow I responded to an old post of yours.

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.

Hey guys, I'm fairly new to the android scene when it comes to the rom and rooting side of things so I just have a few questions about Sunshine and the whole process in general. Sorry if this may have already been asked but after a quick search many of the answers to these questions seem to be outdated.
1. Do you need to be rooted in order to use Sunshine?
2. If I do, is there any method to root my phone? I can't seem to find any without paying some money.
The only reason why I would want to root my phone is so I can use Titanium root and back up my data.
3. Do I have the order right?
Use Sunshine (gains S-off/unlocks bootloader)Install a custom recovery (TWRP)Super SU (Does this root my phone?)Install Cyanogenmod
4. If I have the order correct, at what point should I backup my data and when would my data get wiped?
5. And if I'm backing up my data should I back it up to my SD card and remove it, or do something else?
Once again, I'm sorry if most of the answers to these questions seem obvious but this is my first time tampering with my phone so I would appreciate any help!
Ok so a little update, I used sunshine, installed twrp, and tried to flash super su but I got stuck on a bootloop. Any help? I tried wiping the cache/dalvik.

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 ?
