Alright, so I'm new to XDA, this is my first thread, and I am also slightly ignorant about rooting. I have an Evo 4G running Cyanogen 7. The problem that I am addressing here is that my phone is telling me that it's not rooted, even though it plainly is, as I am running Cyanogen, and not Sense. Apps like Rom Manager and SetCPU are telling me that I don't have Superuser, and terminal emulator says "permission denied" when I type in su. But, there is a Superuser app in my app drawer.
Anyone have any similar problems or know how to fix this one? Thanks
Hello. I cannot diagonse what your exact issue is but I can offer some suggestions. Go download the su binary file and flash it via your recovery and see if that fixes it. Otherwise try "rooting" it again, in other words, re-executing the exploit to acquire root. For the latter option i reccomend removing the current su program first.

Where can I download the su binary file...?

I rooted my Zoom wifi long ago. Flashed all the various Tiamat kernels and followed bigrushdog's 3.1 update with no problems. I recently flashed the CWR RC 4 over the updated 4.0.1 version in Rom Manager. I now see that all my apps requiring root don't work. I have Super user app but don't get the request to grant su anymore. I tried upgrading Super user within the app but it fails and writes a zip update to SD card which is supposed to be flashed through Recovery but doesn't (I suspect because the file is a 0 byte file!).
Any suggestions on how to get root back?
[Solved]: Seems it was a result of trying to upgrade Superuser that I lost root. See the last post below and the solution Almighty1 offers. It worked and I have root back......

There is a problem with the latest recovery version in Rom Manager. The recovery from solarnz is probably not at fault, but maybe the interaction of the two. You wil lneed someone with more knowledge than me to help you get root back, but this issue really needs attention. There are several updates to apps that seem to be breaking our Xooms, and there should be pinned warnings or the developers should be making everyone aware of these conflicts as soon as they find out. I had problems and I'm sure a lot of other folks have have problems with these incompatible app updates as well.
Thanks for that. It almost seems like Superuser is "degrading" in the sense that I had a number of apps reflected in the Superuser app as having been granted root (but not Rom Manager). However, I couldn't add new apps to it. And when I cleared Superuser data and reinstalled it, none of the apps that required root (and which had worked before) would work.
I also think that the writing of a 0 byte zip update file by the Superuser app indicates a problem.
I suspect the solution may lie with fastboot and re-pushing Superuser and CHMOD(?) file permissions but like you, I am nervous to play with these sort of things. My Xoom is working and until I have the need to change the ROM, root doesn't matter to me....
after reading this I checked and also had lost root. I had not checked after after flashing 4.0 in rom manger. Superuser was still there but my apps did not have access. I tried flash a new recovery, reflashing Tiamat nether worked. Anyway from adb
adb remount
adb push su /system/bin/
adb shell
chmod 4755 /system/bin/su
exit
adb push Superuser.apk /system/app/
I then rebooted and had root... updated Superuser as I had an older one in my platform-tools and all is well I then flashed the lastest recovery in rom manger and still have root.
Hope this helps
Thanks. I will give it a try this evening when I get back from work.
Also found this: http://forum.xda-developers.com/showpost.php?p=14643716&postcount=340 which seems similar to your solution.
This is why I hate CWR. I wish we had Amon RA recovery.
would have just asked in :

but i don't have enough posts, and don't want to spam a bunch of useless "cool" posts to get my count up.
Anyways,I did every thing in that topic and have CM7 running fine on my Cell South Showcase. But, i don't seem to have root access superuser is there but seems to do nothing. i tried checking via the terminal with just a "su" command and got nothing. Tried Superoneclick (my go to rooter for awhile) and it just hangs at "looking for device" . and, Z4 seems to not work with 2.3.4 phones.
So is there any fix to this, or have i just hit some crazy bug?
I have seen some people allude to changing the kernel, but the last time i tried to upgrade/change the kernel on this phone i had to save it via odin
Don't you HAVE to be rooted in order to run cm7?
i know, it breaks all logic
i just know i cant grant superuser to anything, busybox installer says it isnt rooted, and Titanium cant do anything

Clear data on superuser app and/or uninstall/reinstall it.
Ah,I see.. yes, try above. If no. Maybe wipe and reflash?
ok cleared the data, did nothing
can you ever uninstall/reinstall superuser?

Yup just an app
Also:
i have already flashed via Odin back to stock once and did the whole CM7 flash again from a fully clean rom
ok, Flashed Superuser 3.0 beta 3
no go, says my SU binary is out of date, and the app crashes when it tries to update it
checked my bin and xbin, both have a "SU" file in them
in terminal when i CD in to both folders and try to run "SU" i get an error that looks like it is trying to relocate a library and failing to do so
Can i just download the new SU binary my self and manual drop it in to the folders?
well that didnt work, cant modify anything in the system folder so i cant delete that old "SU" and replace it with the one from the superuser 3.0 apk
LOL
well i got it to let me replace the SU in /bin but not in /xbin
so now i got some half confused phone, i can grate Superuser "superuser" but when it tries to update or do any thing the log says "gaining root access....fail"
i still dont know how i have have a CM7 phone that by it very nature is rooted that thinks it is not rooted
ok for anyone who cares, i just gave up flashed via odin back to stock and tried the MIUI port, worked great once i fangled MMS in to working again
I had a similar problem, at which point I grabbed stericson's busybox app from the market which allowed me to flash a working busybox which after a reboot or two and running the installer again fixed me up..there is an app called root checker that can give info on su, superuser.apk, and busybox installs
I am almost positive that when I used jrummys busybox installer our killed root access on my phone. I had superuser.apk but without busybox it was rather useless as no apps could get root. the fix was flashing busybox 1.19.0 and leaving it in xbin and letting the app do its thing once I had rebooted.. then I rebooted again and everything was fine! after bring rooted for so long I don't think I could function without it!
for others out there, my experience has been this: stay weary of the jrummy busybox installer...its never given me anything but problems...and honestly unless busybox is borked, or ya have a damn good reason to upgrade or downgrade my suggestion is to leave it! the potential problems that can arise (for me every time, using jrummy's version..3 times) can be a pain!

i had the same issue but dont recall if it was CM7 that did it or not but i think it was.
i had to completely blow out the phone and start from scratch.
if i recall, CM7 uses a different version of SuperUser and it just want bonkers on me but completely blowing everything out reformatting and everything seemed to work.
If you're on CM7 already, you should be rooted. If not, try SuperOneClick (Google).
Okay so everytime i open an App that needs a super user permission, a notification shows up saying my "#su binary" is outdated. So I tried updating it but it fails. I researched and read somewhere to update is manually. So i downloaded an Su Binary and replaced the old one with this new one. It worked and all but heres the problem. The old apps that are granted Superuser Permission is no longer in the list. When i open them it says "superuser not granted" and doesn't give me the option to allow or always allow.
So here's my question, how to i allow superuser permission again?
You have to get busybox from the market first then u can update superuser

T_T It was denied superuser Access, also rom manager is denied superuser access. How do i fix this
Sorry for double post but after using the Root checker, i found out my phone was no longer rooted. So i used oneclickuser again and rooted it. It returned it to Su Binary v2.3.1-ef from v3. The build and the baseband version are still the same. Yay, i think i just messed up on replacing that SU file instead of actaully updating it.
Well I hadthe same issue then installed busybox and it fixed it. But deleting something something u need someone that can help more than me lol. All else fails start over ...... I just learn by xda what I did wrong and if that don't work I start from scratch lol. Hopefully. Someone will help u soon.

I got my HTC One X about a week ago now for AT&T. Almost immediately, I tried rooting but ran into an odd issue.
Before rooting I had installed Apex launcher. There is an option in the settings to enable Root Helper, which previously would give an error message of something like, "This device does not have root access"
I went through the rooting procedure as detailed here on my mac. The script didn't work at first until I realized I had to switch it to Unix from DOS (Didn't look at the script before running) after I fixed it, it ran and rebooted twice and everything looked normal. Now I tried using the apex root abilities and it just froze and crashed.
So I booted up windows and tried using that to root, but the exact same thing happened. It seems to recognize my root, but not actually give any permissions.
I've tried using other root apps such as uninstallers,titanium backup, etc and all of them just freeze when trying to get elevated permissions.
Is there something wrong with my phone or the way I did the root?
Have you tried clicking on the su app? I had to upgrade mine.

Yea load up the Su app and ugrade binaries. That should fix the issue. Ive had issues like this on other phones.
You could also try running paulobrien's root method. That's what I used, and my phone's good.

I've also had a situation where the Busybox version installed on a custom ROM on my HTC Flyer tablet interfered with some apps (like Titanium). Make sure Busybox is up to date. I even had to install a different Busybox installer in order to get it to work right on my Flyer in that particular instance. I had to use the JRUMMY16 version in the market, and not the Stericson installer (which seem the most popular).
No packages were installed with the root.
I'll try using paulobrien's method later and hopefully that will work.
I'll start out by saying I'm a total noob at this whole android rooting process, hence why I'm posting a thread here rather than posting a reply in the appropriate thread. I rooted and unlocked my phone using this guide: http://forum.xda-developers.com/showthread.php?t=1762709&nocache=1
I opted for the "flashing rooted stock ROM" option.
As the title of my post states, after installing CM10.1, I open superuser to update binary and everything appears to work fine until the very end, it reads "making sure new su works...fail!". Now when I restore back to rooted TW, I have no problem updating the su binary. I've tried Superuser update fixer, I've installed busybox; i cant find any other solution on Google. Any ideas?
The CM file I downloaded is: cm-10.1-20130714-NIGHTLY-d2vzw.zip

Make sure your using the latest version of the Superuser app, another option would be to try using SuperSU as an alternative to the Superuser app. Also is root access functioning normally for you?
Sent from my SCH-I535 using xda premium
Hi and thanks for the reply.
Yes superuser is up to date and I've tried supersu. Root seems to be functioning as I can open apps that require root access.
But when I try to restore missing apps via titanium backup, I get a msg saying "restore finished, 'x' elements failed". X being the number of apps I try to restore

Check to see if the root apps are granted root access.

When I open SuperSU, it has a list of apps with superuser status. Is that what you mean? I can run root apps and as far as I can tell they're functioning, with the exception of when I try restoring apps with Titanium Backup
Also, right after I flashed CM10.1, I made a backup right away. Not sure if it means anything, but If I wipe/reset and restore the CM10.1 backup, and the first thing I do is try updating the binary in Superuser, it reads "checking installed version: 9 com.Android.Settings", until I open SuperSU and "update binary". Then if I go to Superuser, it'll say "checking installed version: 1.41:Superuser" as I imagine it should. But at this point I still run into "making sure new su works..fail!"
Superuser has no problem updating when I'm on my rooted stock. I'm sure I messed up somewhere along the way while flashing CM10.1, I just don't know where
