Hi,
I am trying to root my SGS2 and I haven't rooted a phone before. I am using CF-Root and have followed the instructions on:
http://forum.xda-developers.com/showthread.php?t=1103399
That all seemed to work and when I boot my phone I get the yellow triangle, etc. But, according to Root Checker my phone isn't rooted and if I try to run an app that requires root then it doesn't work.
Do I need to do anything other than flashing the CF-Root tar in Odin to root the phone?
I used the following kernel (my phone was previously using LPC so I assume this is correct):
CF-Root-SGS2_BU_VOD_LPC-v5.4-CWM5.zip
I have searched and can't find any answers so hopefully someone here can help.
Thanks,
Jon
flash the same again an this time ull b rooted
as rock23 said reflashing should solve that issue. If you are missing the SU specifically. Then you can install it from the market.
Thanks for the quick replies. I flashed again but it's still not working. Just in case it helps, I flashed a third time but still no luck. Odin seems to run properly and reports success. But Root Checker says:
Superuser: Not found
Busybox: Not found
Su location: Not found
Sudo location: Not found
And if I ran an app that needs root then I am not prompted to allow it, etc, and the app doesn't work. Any suggestions for what I should try?

Sorry, I might be misunderstanding this, but I can't find su on the market. There are apps like superuser, etc, but I can't find anything that delivers su. Shouldn't that have come with CF-Root or do I install it from somewhere else?

Install super user from here

Thanks. I have now installed super user but 'su' is still missing.
In super user preferences it says "Su binary vnull" so I tapped that to get an update. Super user says "New version of su binary found" and I click "Update" but that fails with the error "Failed to find currently installed su binary".
I can't see how I get this su binary.
Flash a different CF root firmware .
Ignore root checker .
Reboot and you should have CWM apk open that and if it works check recovery works .

Thanks, I think I'll have to try a different CF Root kernel because the one that's meant to be for my Kernel definitely isn't installing some of the things that I think it should.

I dont thik you have to flash different again,
have you opened atleast once the Supe SU application, there is a binary updatin, at your first opening, may be alright after that and a reboot.
I am currently using LPC cf-root on my LP8 rom without any treble....
The weird thing is that I couldn't even find SuperSU on the phone after flashing with CF-Root...I definitely had an insecure kernel but the other things needed for root didn't seem to be there (or at least didn't work). I gave up with CF-Root and tried the root method described on the following link and that worked first time (although wifi then broke until I changed to a static IP):

I had this problem. No superuser installed after flashing. Couldn't update su binary with superuser. Here is how do you solve this issue:
1) install superuser from market
2) flash manually su binary with cwm http://downloads.androidsu.com/superuser/su-bin-3.0.3.2-efghi-signed.zip
3) open superuser go through prefences and check updates if any.

Hi,
I'm using CM 7.03 on my Legend and it was working really good.
However yesterday i was stupid enough to install an update of superuser.
After this update root access was still functioning but i was getting a "su binary is outdated" message.
So i tried to update this,but the update failed.
So i went into rom manager,downloaded Super User 3 and flashed it,i shouldn't have done this.
After phone booted my root access was gone,and whenever a program asked root access it showed a forced close window of the su app.
My question now is....can i fix this without reflashing the device.
Keep in mind that rom manager isn't working and i can't boot into clockworkmod.
I also tried softrooting in order to gain access to the file system but this also failed.
Any help would be greatly appriciated.
Thanks!
Edit: Just a brainfart,but would it work if i copied the correct superuser version to my goldcard,rename it to update.zip and flash it?
try to update to the latest superuser..
btw.. you are on which cm7?
before this.. im on cm nightly 195.. got some error when updating superuser binary..
but now im on latest cm nightly with updated superuser from market.. successful update the binary through the superuser setting interface..
i had the same problem & was able to fix it after the same steps you've taken by installing the superuser.apk from the flashing-.zip file again. there have been updates of superuser application in the market since, maybe they will fix the problem too...
Rom Manager has the superuser 2.x,too.You can download it and reboot into recovery, flash the bag( at /sdcard/clockworkmod/download/goo-inside.me/superuser/(THE SU YOU WANT TO FLASH).ZIP
Flash it and the root access will back~
ps.It seems cm 7 haven't supported su3.0....About 1 month ago, I flashed the su 3.0 and it always told me access deny...Finally I have to flash the su 2.x back...
About the recovery,you can plug the phone to computer and in recovery mode(HAVE A RED ALERT TRIANGLE), run the recovery-windows.bat( it is in the r3(or 4)-legend-root.zip), and you can flash anything you want.The HTC raw recovery( with only 4 items)cannot flash the su package even with the goldcard....

Hi,
thanks for the advice.
I'm gonna try to reflash the correct superuser.zip,that's how i wrecked it in the first place.
Also i didn't know it was impossible to do this with the raw HTC recovery so i will use the suggested batch file.
Thanks a lot guys,i'll come back and post my results.
My fix
Had the same problem on a nightly.
I did just download su-3.0.2-efgh-signed.zip from superuser website and flashed it and then it worked fine after that.
[SOLVED] CM7 lost root access after su update
Well,it isn't going like it should.
I just can't get into recovery.
I'm trying in VMware,running Windows XP (it never worked before on Win 7 x64),i've installed the correct version of HTC sync but when i run recovery-windows.bat (from hack4legend) i just keep getting errors...
failed to copy files etc/mtab.... (file system read only)
--install: applet not found.
nohup: appending....
Can't figure out what i'm doing wrong,it look like it needs root access but that's what i'm trying to fix.
Help?
Edit: Whoops,forgot about the red triangle...i can get into recovery now.
Edit2: Just flashed the correct su.zip and root access is restored!!!
Thanks a million guys!!!!!!
Sorry...but are there any screenshots?
Edit :errr...yes,you must get into the red triangle screen....

I'm running CM7.1 on my ZTE Blade and yesterday i've tried to update both superuser and su (since new versions have been released). The su update failed and now when i try to check the su version it says "Legacy"
If i try to update, the phone stucks at "Getting root privileges" both on Superuser and Superuser Fixer
What should i do?
I've got the same problem on my Xperia X8 with the stock rom, it seems that the problem is that the updating progress fails at a point where the old binary has already been removed, but the new one hasn't been placed yet, leaving you with a non-rooted phone.
Seeing how I've never tried doing some real programming for Android I wouldn't know how to get the new binary in.
I've tried installing an update.zip containing both the full SU with .apk and a version with only the binary, but to no avail.
Trying to reroot my phone using SuperOneClick results in SOC freezing (might be a problem with windows 7, as I have upgraded recently).
If anyone knows a way to fix this issue, I'd be very grateful.
For now I've fixed my problem reflashing the old su and superuser from cwm. You can grab them from downloads.androidsu. com/superuser

Yes, or any other recovery.
So I used the rooting guide at http://forum.xda-developers.com/showthread.php?t=1996389 and found a different superuser/busybox package to use. (don't remember the link right now).
However, whenever I open SuperSU to try to update it, it says installation failed or just reboots. And if I try to use root things for AdFree, it can't find the partition or just restarts.
Is anyone else having this problem or is there a different SU package I should use? My bootloader IS unlocked.

Ive been using ViperDNA which comes with what seems like a custom SuperUser type of all in it.
But when I origionally rooted my phone, i seem to remember having an issue with SuperSU, and the first time i rooted i said screw it and just installed Superuser without any problems. The second time i rooted, i Installed SuperSU, then had to download Superuser form the Android Market, to update the binary, which updated it for SuperSU, and that solved my problem.
When you try to open an app that needs to use root access, do you get the notification asking for permission?
perhaps the "other" superSU/busybox package that you used didn't properly do what it needed to do?
I see the link on that tutorial is broken, fortunately i have the file that i originally downloaded form that very same tutorial saved to my hard drive, and now uploaded to DropBox if you would like to download it and try flashing this zip while in recovery to see if it gives you a proper root.
I would recommend downloading the above file, and flashing that to see if it helps. I'll try to remember to check back here to see if you posted anything in reply, but let me know if it doesn't work. Ill try to help as much as I can

I installed your package, and get the same errors before in SuperSU. It wants to upgrade but then force restarts whilst trying.
I then tried the Superuser app by Chainsdd, and I make a little progress?
First, when I try to upgrade, it asks for root from SuperSU and Superuser. Since SuperSU came with the busybox package, I can't uninstall it.
When I first go to the updater, it shows me this: (See attachment 1, I can't do links :S)
After I upgrade it, I am left with this screen: (see attachment 2)
It looks like it reverts back to su v .98 from 1.02?
Either way, as soon as I hit lets do it again, the phone restarts. Did I screw up the unlock/root somehow? In the top left of my fastboot screen it shows ***TAMPERED*** and ***UNLOCKED***
I am using CWM 6.0.2.1

It's difficult for me to troubleshoot when i haven't had to fix this problem since december haha.
The tampered, and unlocked is standard that is what it shows for everyone who unlocked the boot-loader.
So let me get this straight,
Do me a favor, un-install Superuser, download RootChecker from the market by JoeyKrim, And run it, what does it say?
->When you run it, did it ask for permission from SuperSU?
With just the SuperSU installed, if you run a program that requires root permission (For example, RootChecker), Nothing shows up asking if you want to Allow/Deny?
->When you open SuperSU to update the binary, it fails to update and restarts the APP?
With the SuperSU/BusyBox package flashed, when you install Superuser from the android market and try to update the binary, it *appears* to revert back to an older version of the binary?
-> After updating the binary through Superuser (despite the appparent reversion), if you un-install Superuser, and try to run RootChecker, does it work?
Sorry, i know it is a lot and i'm not much help, i'm troubleshooting blindly and from a distance haha.

you need to install a kernel with /system writing enabled. Such as lk's or cubed
htc has a line wrong in their code and it makes it so that /system cant be edited while booted into android, only while in recovery. Installing a kernel that fixed this bug will let you use supersu from the play store and other apps such as adfree which need to edit system files to function

Even with a writeable kernel SuperSu gives a hiccup at first. Download SuperUser, update the binary of SuperSu, then uninstall SuperUser. SuperSu will be fine after that.

Next time, you could just install custom kernel, download a rooting flashable zip file and install it via kernel's Recovery. I do it often, because I prefer to use Clockworkmod's Superuser and by that zip file, I avoid any kind of problems.

Hi Folks,
I recently inherited a Samsung Galaxy S II. (The previous owner upgraded to a Note 3 which soon has to be rooted too! )
To my knowledge this phone was already rooted to upgrade it to JellyBeans before this was officially available from Samsung.
To get to a clean start I went through the recovery mode (VolUp+Home+Power) and initiated a factory reset.
Thereafter I installed Titanium.apk from the SD-card, which tells me now that it can't gain access to the su command. Does this mean I 'unrooted' this phone wit the factory reset and I have to undergo the rooting procedure again?
BTW: After reading through the forum for a couple of days and following link after link, I still have the feeling I went in circles without really finding the basics to build my knowledge upon. Could someone please point me to some information on how to decode or interpret the 'cryptic' Product-, PDA-, Phone-, Modem-Codes (like XXLS7, XWLSD, DBTLS7, etc.)?
Cheers

You could have fixed this 4 hrs ago if you'd flashed a custom kernel.
