I rooted my Nexus 7 a few days ago and was able to replace bootanimation. But now I want to replace my new version of bootanimation using Root Explorer, I found I have no super user access (the terminal prompt does not change from $ to # when I type su at the adb shell). The /system is mounted as r/o. I also have the busybox and supersu zip files on the sdcard. Can anyone please tell me what happen here and help me back to su mode? Thanks in advance!!

I can't see any reason why you'd become unrooted unless you either replace the system partition (via an update or rom change or fastboot flash or whatever) or delete the binary yourself. If you didn't do either of those it could be either a problem with supersu, a problem with the binary, or a problem with your kernel. Try putting the root binary (su) back on the phone and trying again, and if that fails try using SuperUser instead of Supersu. If neither work you may need to do a factory reset and try again.
did you upgrade to 4.1.2? You must have lost root during the process. Just re-root it. I used the toolkit.

oh, yes!!!! I just upgraded a couple of days ago from JRO03D to JZO54K. THANK YOU!!
I tried re-rooting again (w/o flashing custom recovery) after I upgrade Nexus Root Toolkit to v1.5.4 t support 4.1.2, But get stuck at the message "waiting for your device to finish booting back up." Nexus 7 is at the TWRP mode and can't get out of it. So I reboot to bootloader mode and eventually the toolkit tells me to run SuperSU and Busybox. Still doesn't work since I still don't have super user access. What shall I do next? I know there are still few more steps after the TWRP.

I cannot gain SU access on ADB Shell after performing the flashable root zip suggested in the update.pkg thread.
Sure root and superuser work on the phone itself. But i got no ADB Shell powers.
anyone else have luck with this?
I get permission denied
It appears my flashable root got messed up by trying to fix permissions in streakmod recovery. Just reflashed and i believe it should work now.
Sent from my Dell Streak
works on mine perfectly.
I did have to install Busybox system/bin .
it works fine
it appears that everytime I flash a clockworkable zip with streakmod it breaks my root.
The only way to get it back is to reflash the root zip. This isn't good.
Same here, fixing permissions screwed up my root. I'm back on 319 until a better root comes along (if it ever does)

I downloaded busybox from the market and installed the 1.17.1 and it worked fine after that.
Goodluck
I have N7 running 4.1.1, it's rooted (supersu) and unlocked (cwm).
I received a notification for 4.1.2, should I try enable "Survival mode" through SuperSU and let it upgrade? or do I need to load stock image (loose all of my stuff)
OTA won't successfully update if you are not running a fully stock device.
i.e stock ROM, kernel, recovery
Also bootloader should be locked and device should be unrooted.
You can backup apps using titanium backup or something similar.

If you have not modified the /system partition or the kernel, you will be able to run the OTA from ClockworkMod. As far as "losing root" is concerned, the issue is that the permissions get reset by the OTA update - the binary is still there. You can fix this yourself following these steps:
Download the JZO54K-from-JRO03D OTA update and copy it to your sdcard
Install the OTA update via CWM.
If it succeeds, leave the device in recovery mode and connect to the device via adb:
Code:
> adb shell
Once you've connected to the device issue the following commands:
Code:
# chown root:root /system/xbin/su
# chmod 6755 /system/xbin/su
If using Superuser, the su binary lives in /system/bin instead.
If you don't feel like learning, you could always use a toolkit :silly:
protip: dont use toolkits.
What if you have changed something?

So I have deleted one or another pre-included apps I wasn't using. How does one do a 4.1.2 upgrade in such cases?

Same here. I had to use the update linked in post below.
http://forum.xda-developers.com/showpost.php?p=32752631&postcount=20
I have been reading through previous threads but I cannot find anything that specifically answers the question I have.
I had stock Android 4.2.1 (which was rooted) and now that it has updated to version 4.2.2 I am unrooted (even though upon boot it still displays the unlocked padlock but I assume that is something different).
So my question is, is it possible to root my current stock 4.2.2 and keep all of my apps and data? or is the only solution to wipe it all and start again if I want root access?
As a side note and to anyone who is reading this if you are currently rooted install this https://play.google.com/store/apps/details?id=org.projectvoodoo.otarootkeeper&hl=en and hopefully that should be the end of having to worry about losing root but in hindsight it is obviously to late for myself.
Thank you very much to anyone who can help me!
You didn't read enough threads.
The bootloader has been replaced, but is still unlocked.
The OTA also overwrote your custom recovery with a new stock recovery, but that's only a temporary issue - read on.
Because the new bootloader is also unlocked, that means that you can re-install a custom recovery just the same way you did it originally (with fastboot or a toolkit which also uses fastboot), but without the unlocking step (which wipes everything).
After you have a custom recovery in place you are free to do whatever you want - you could just reinstall a minimal SuperSU/Superuser overflash. This leaves everything unmolested, and you have root back.
Note that the superuser software is still on your tab; it has been temporarily disabled because the 'su' binary got its' permissions reset by the OTA install. Without doing a new over flash you could simply perform (with the custom recovery booted)
adb shell mount /system
adb shell chmod 6755 /system/xbin/su /system/bin/su
adb shell ls -l /system/xbin/su /system/bin/su
(it's one or the other of those locations depending on whether you are using SuperSU or Superuser; in any event you should see "swxs-xr-x" if you have the correct setuid/setgid permissions set)
good luck
The unlocked padlock means you're bootloader is unlocked, which is fine.
Yes it is possible, I suggest reading the stickies which explain how to do this. Basically, you'll need to flash a custom recovery via fastboot, then download a SuperSU flashable zip file (or Superuser) to flash in the custom recovery, and that's all.

Thank you both very much for your responses!
I rooted my Nexus 10 using the Google_Nexus_10_ToolKit_v1.3.0. When I did this I used SuperSU as my super user app.
After being successfully rooted for over a month my device is no longer rooted.
When I try to open SuperSU I get this message:
"There is no SU binary installed, and SuperSU cannot install it.
This is a problem!"
I no longer can run applications that require root access.
I tried installing Superuser and did the fix associated with that but it failed as well.
I haven't done anything to my device except for root it. Why would it all of a sudden become unrooted?
I still have the unlock icon on my boot screen.
Can anyone help?
Did you apply the 4.2.2 OTA update that came out recently? Updates will often unroot the device by removing suid from the su binary.
Easy enough to fix with an unlocked bootloader,new enough versions of Clockwork Mod recovery will check and fix it for you, or you can use adb with any of them to chmod u+s the su binary.
Edit: or use TWRP, was thinking of the Galaxy Nexus.

Yes. I think this problem happened right after the 4.2.2 OTA update.
I am not able to get into my recovery. When I try I just get a picture of a dead alien with a red triangle.
Do you happen to know the exact adb commands to perform this? I've tried search but I could not find anything.
Thank you for your help.

That's stock recovery. You need to use fastboot to re-flash just your recovery.
The adb command is something like "chmod u+s /system/bin/su", from the recovery (where you'll have a root shell in adb).
Or you could just install the superuser zip file from your recovery, once you've got the recovery running again.

I tried accessing fastboot but the Nexus Root Toolkit says I do not have a fastboot enabled device.
I tried running your command but nothing happened.
Do you have any other suggestions?
You could try installing the recovery through the Goomanager app. Once installed select menu and install recovery script.

this happened to me also.. but my nexus 10 is more than a month rooted.. from out of nowhere it suddenly becomes unrooted, caused by an unkown reason.. it didn't made any notification/alets or any dialog box when it suddenly becomes unrooted.. i noticed it when i used sb game hacker.. it says that the device is not rooted.. anyway i'll find a way to root it again this weekend..
I'm a bit confused. I'm on my Nexus 7 right now which is running a custom ROM. I can boot into bootloader as well as Clockwork Recovery. However when I just tried to run a backup using titanium, it told me my device is not rooted. Superuser is installed. How can this be? How do I gain root access so I can backup my apps before putting on a new ROM?

Download to your Nexus 7, Chainfires SU updater package from here...
http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip
Reboot into CWM/TWRP (whichever recovery you're running) and flash it...
(You should find it in the /download folder)
Reboot as normal... you should be rooted.
Rgrds,
Ged.

So I followed what you said but I was still getting the no root error when launching titanium. Then I went into settings and uninstalled the SuperSU app and viola! Everything is working now
You probably had root disabled under development settings, as is the default. By installing and uninstalling SuperSU, you may have overridden that security setting. It is important to check whether an app is actually handling such requests; otherwise any app could get root without your knowledge.
