Hi all,
I rooted my galaxy s 2 a few weeks back with no problems. I followed the dummy's guide on a different forum, using odin and flashing a new kernel.
But then I decided to unroot which I did with no problems either -I went into the superuser app and checking the unroot box which uninstalled superuser and removed root on the phone (it left CWM though).
Today, I've decided to reroot it like I did the first time. However, this time superuser didn't install and I don't have root access at all.
Any ideas on what I should do?

Given you're using a method from a different site that people here may not have experience with, no idea. Me, I'd flash a CFRoot kernel (assuming you have an I9100 or I9100T; if you don't, do not flash one of these kernels. You might end up bricking your phone). Instructions in this thread are very clear, take your time & read the first page thoroughly & make sure you understand the process clearly before you try it. The section in bold red which says 'Help ! Which file do I use ?' has the info which will help you work out which CFRoot kernel to use.

Thanks for the reply MistahBungle. That's exactly the process that I followed. Didn't have any problems with the rooting process - downloaded the LP9 kernel, entered phone into download mode, and flashed the kernel using Odin. Got the yellow triangle.
I suspect the problem arose because I 'unrooted' it through the superuser app, which then got rid of the superuser app?
Today, I tried following the same process but superuser won't uninstall. I downloaded the root checker basic app which also said the galaxy s 2 doesn't have root permission even though I followed the same process.

Yes I have downloaded and installed the superuser app from the market, but it doesn't have any root permissions I don't think. I also tried opening up the CWM app but it says it needs SU permissions (which it doesn't have because SU is not installed and I cant seem to root it).
What to do? I'm thinking of trying another root method on xda i.e. the busybox one that doesn't require flashing an unstable kernel.

Greetings all!
I have been a long time user, first time poster, but have rooted my phone many times with success, however after a mini update today, the rootkit I used last time kind of worked, however most of the root functionality no longer works. I assume im just using an out of date rootkit.
Model: GT-i9300
Android Version: 4.1.2
Baseband: i9300BVELK1
Build: JZO54K.i9300XXELLA
The device does say modified but the apps still function as if it isn't rooted.
I am on Orange France Telecom living in France, using the handset from Orange. Which software download do I need to get the root working correctly please? I have checked alot of the guides but all point to what I assume is an out of date rootkit.
Thank you for your response in advance.
You can try updating the binaries from within the app.
And please don't ask questions in General

How do I do that please? I am concerned I will break my phone if I mess too much. Very much a beginner with rooting outside of the guides.
Go to the superuser app and do it there

I may have been unclear, I don't know what the phrase "updating a binary" means. Thank you for taking an interest in helping though.
Also the version of the root software was Odin 1.64 I think (working from memory as not at home right now).

Does anyone have any advice on how to fix this please? I am sitting at home now and I think I was using 1.85 Odin not 1.64. Why does my device say modified but still won't give me root access to apps etc.

You should root using this its ptobably the best and easiest way
http://forum.xda-developers.com/showthread.php?t=1957273
Download the zip from post 3 extract the MD5 file and flash via odin 1.85 is ok
Ok...
The problem being is that the root hasn't worked. I get through the root, but each time in the past, it does some file verifying where it says "verifying 1 of 145 files" or something similar, and then adds SUser and CWM - It doesn't do this after this root, and the phone, while saying rooted, won't work as a rooted phone. All my unlicensed apps now fail to load.
I really think that the micro update installed via KIES today needs a new rootkit. I tried the above update, and all that did was delete the Super User app too >_<
Thank you for your patience so far. This stuff is very complicated outside of the normal rooting.

If you use CF Auto Root and lose SU just download SU from the market, this one

CF Auto root doesn't contain CWM you need to install that seperately or install TWRP recovery

Ok so made a bit of progress, got the SuperSU on there again, but apps still function as unlicensed. This was all working fine until the update this morning, but at least we are progressing.
Still haven't solved it. Some apps work, some don't. I even tried Lucky Patcher, no joy.
Hello, I am a complete noob with android software and these forum websites.
I bought a the standard Galaxy S2 GT-I9100 a few months ago, rooted it but since then I still have no root access. This is the first time I've signed up for any website to ask for help, because I cant find any solution to fixing it.
I followed a simple guide, which instructed to use odin, and the Siyah kernal. It said the root was successful and superuser + CWM was installed.
On the Superuser Binary Updater, its says the latest version is 3.1.1 but I only have 3.0.3.2. When I try update, it says "Gaining root access... fail!"
The 'Root Checker Basic' app tells me "This device does not have proper root access"
I was suggested to use OneClickRoot. I try it, and it tells me my device is already rooted.
I am using:
Android version 4.1.2
Baseband version I9100XXLS8
Kernal version 3.0.31 siyah-s2-v6.0b5
Please help me gain root access without wiping the data off my phone. I dont want to modify the way the system looks or works, all I want is root access. Sorry if this posted in the wrong place, this site is confusing for me
Flash Siyah again (through CWRecovery if the flash was successful enough to install it, if not through Odin again).

I've tried doing it again through Odin and still no change. Is it possible that I'm doing it wrong? After many searches I see there's multiple ways of rooting the device..
Can you please link me to correct instructions for using Odin? Just to be sure I'm doing it right
Siyah tar file in PDA section of Odin, click start. I don't know why people think this sort of thing is complicated when it's really very simple.
Hi guys I recently rooted my phone and thought that if I could refresh my tablet a bit with a new rom Id use it more so I decided to root that too.
I have followed a lot of the guides on here but am really having issues. The Superuser app just will not work, I have copying and pasting in the new version and rooting again, I have tried unrooting and doing it again with no superuser.apk file at all or a bin superuser file and still no.
I cant even check if the device is rooted correctly as root checker just will not come up with a result it just loads forever.
I tried installing SuperSU instead but it gets stuck on installing then it says there is another programme that may be conflicting and then it just gives up too.
What to I need to do to root this thing and have a working supersu/user app?!?
Thanks

I had the exact same issue just the other day. Is the rom a 4.3 version. They are apparently a little finicky. First, open developer options, and under the root part allow apps and adb. Then I flashed the supersu from this site here , and finally I simply re flashed the rom I wanted, and it worked.
Hi All,
In my quest to learn a little more about my device, I've decided that I want to know how rooting is actually done manually. Where it stands, my device is currently rooted using a CF Autoroot Odin flashable (recovery?).
I saw that Super SU provides a CWM flashable zip but I suspect that it's the same as sideloading the application or installing it from the store and that won't be enough to get rooted. Or is it?
Bumping my thread :laugh:

(1) please read the FAQ and stickies to understand what rooting is and why CF autoroot has nothing to do with recovery
(2) cf autoroot, if I am not wrong, but I might be, injects files that will enable you to have full access to the device, after that for instance you can flash a new recovery, use apps that need root etc. super user is the app to control which apps you allow to obtain root.

I've read and followed the procedure for rooting ang flashing with a custom recovery previously but I've followed your suggestion and re-read it anyway, in case I missed something or my memory loss kicked in again.
Perhaps you are correct. I was a little confused since I flashed it with Odin as well but come to think of it; it's like an upgrade package that, as you mentioned, uploads files to the device that give Superuser Access.
after that for instance you can flash a new recovery

I've flashed a custom recovery before rooting but I suppose that only applies to some devices. Samsung is great because it has Odin!
Alright, so SuperSU only allows me to control what applications require root access (something like User Account Control for Windows).
Thanks for clearing that up!
As for my original question, the manual rooting process and what's required to gain root access seems undocumented since there are a ton of methods to accomplish it automatically. I hope someone can point me to the right place to understand what CF Autoroot or other apps actually do to gain root.
(I cant post to the original thread, but im hoping someone here can help me please?)
Ive rooted 6 or so different android phones mainly using cf-autoroot, including an i9300, and never had any issues. But I have had a few issues rooting my 9503 using the cf-autoroot method (method #1 in this post). It aooeared to work, but SuperSU subsequently fell over, and Knox complained but after reading other posts I rectified that, but obviously not quite correctly:
After using cf-autoroot, SuperSU DID NOT appear in the apps list, but Google Play said it was installed but only presented the option to open it (not update or remove).
So I then tried flashing twrp (as per method #2 in this post) which all appeared to go successfully according to Odin. I was expecting to install superSU updater, as per step 3, but recovery mode appeared unchanged/stock so of course I couldnt flash anything as there was no option to do so. Yet there were no errors reported by Odin?
So I then got hold of the app file for SuperSU 1.93 and installed it (via Airdroid). It ran. It found knox. It removed it, and root was installed successfully (as verified by root checkers, titanium backup, droid wall and the like). So I concluded I had successfully rooted my 9305.
But when I reboot SuperSU falls over again on boot up, and the version I added via Airdroid has disappeared, and of course there is no root mode.
But I can then restore root access after a reboot simply by following the same process, namley installing the supersu apk via Airdroid.
Can anyone suggest what is the easiest way to get round this, or even why it's happening? And why is the later version of SuperSU disappearing on reboot?
non persistent SU after rooting Android 4.3 - solved
OK, so Im still unsure how I ended up successfully rooted ,but then reverting back to a non-working or incompatible SU version on reboot (presumably the version installed via cf-root?). It's news to me that an app installed via standard means can be overridden for any reason on reboot. One day someone might explain that or tell me the appropriate phrase to use for my friend google so he can explain it to me.
So what I was then trying to do was install a custom recovery so I could flash the latest SU, as per OP. Try as I might I cant. Even removing the battery once TWRP has been transferred using Odin the standard recovery still prevails. So that one is still unresolved.
But in the meantime, as with most well written apps, the answer is within SU itself. Going into Options in the Su installed via the standard app installer, I selected the option to install that SU as a binary. And it worked, so now SU persists across reboots.
Just in case someone else has the same issue, although judging by all the replies I suspect not (or maybe everyone else is able to post to the original thread, although I dont see this exact problem or solutio there).
If it didnt help anyone, sorry for wasting your time!
Hi,
I have the same problem : my root is lost after each reboot.
I must uninstall SuperSU, then update SuperSU end reboot to have the root again.
Could you give me your solution with simple words because I don't understand what you posted befort. Sorry for my bad english ...
Thanks.
