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 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..
So the title pretty much says it all. I don't need root very much. Just for fixing the bluetooth with my Nyko Playad. http://forum.xda-developers.com/showthread.php?t=2138911
Anyway I installed the OTA 4.2.2 update and then I discovered my root wasn't working anymore. I have relocked my bootloader since rooting the first time and I know that if I root again I will lose all my apps will be deleted.
Last time I rooted I use the Nexus 7 toolkit to backup my apps. But certain apps like Need for Speed most wanted didn't backup. So when I restored my backed up apps some of them never appeared again and I lost all my progress.
If I re-root how can I be sure that all my apps will be backed up completely with all their data backed up as well?
Buy the paid-version of SuperUser, and you wouldn't have this problem...
Just sayin.....
Look up carbon in the play store. It will allow you to backup user apps+ data to your PC (if you get the paid version i believe it can sync up to google drive or dropbox to name a few) if you are not rooted. That way you can keep your games positions and apps data, unlock and root, then restore via carbon.
You didn't need to re-lock the boot loader to gain root back. (But now you DO.)
For OTAs that replace the recovery partition, you really only need two steps to gain back root:
- flash a custom recovery (need unlocked boot loader for this) into the recovery partition
- restore the setuid/setgid permission bits on the "su" binary, e.g. with the custom recovery running:
Code:
adb shell mount /system
adb shell chmod 6755 /system/xbin/su /system/bin/su
Alternately (instead of the step above) you could just re-flash a SuperSU/Superuser root kit, or use a "rootkeeper" app.
Any way you slice it it's not much work.
BTW - there will certainly be more OTAs - it's a Nexus device after all.
Thank you everybody.
I will definitely be purchasing the paid version of SuperUser so that I can keep my root after OTA updates.
I'm currently using carbon to back everything up. Then I will unlock, root, and relock. I keep my bootloader locked for security.
Ota rootkeeper will work too, but yes, you will always lose root after an update. How easy you regain it is up to your configuration.
This device seems to be a little trickier to root compared to my old Galaxy S3.
I just received a brand new Moto X Pure, XT1575 (North American variant I'm assuming since I bought it from the US).
It's currently running Marshmallow 6.0, and has been OTA updated to the Feburary 2016 security update.
I want to keep the stock ROM, but I want it to be rooted. XPosed would be nice as well, but not necessary. I do not want any custom ROMs, just the stock ROM rooted.
To root you have to unlock your bootloader, install TWRP, and use TWRP to flash supersu.
For the most part just follow the Heisenberg guide and you'll be fine.
Since you're on marshmallow make sure to install supersu systemless or your system won't boot. Don't use the old supersu linked to the Heisenberg thread. Stay away from the ivcarlos method linked there too; newer versions of supersu handle all that boot image patching automatically. You just have to be a little careful about what version of supersu you use. Supersu version 2.62 works fine. I can vouch for supersu 2.67 too, but you have to force it to install systemless. Enter this in TWRPs built-in terminal or an adb shell before flashing or it will try to install using the traditional method and you'll freeze on the big M when you reboot:
Code:
echo "SYSTEMLESS=true" > /data/.supersu
Just use TWRP to make a backup before you mess with rooting so you have something to fall back on in case things go wrong.

You'll have to use a very specific - older systemless root though. I think supersu-2.64, but I'll let someone else confirm that. The other superusers will not work.

Can someone clarify? I also just got the same exact phone and installed the Feb OTA updates, then unlocked the bootloader.
I just need to enter the following in the terminal and THEN flash Supersu? Is the code below what "forces it" to install systemless? Can I use the newest version of supersu if I pop this line in first?
echo "SYSTEMLESS=true" > /data/.supersu

That command creates a text file /data/.supersu with one line in it "SYSTEMLESS=true". Supersu checks for that file when you flash it, and if it is found with sytemless set true installs systemless.
2.67 is the newest zip I tried it with, but I see no reason why it wouldn't work with newer versions.
Just be sure to backup /boot /system and /data first. If anything goes wrong restoring those will get you back up and running.

It didn't work for me via adb command.... Had to use TWRPs built-in terminal. Just wrote wrote the line, as it is, go back to the main menu and flash Supersu (I used the latest one: 2.67) just as you normally do. Then reboot. No more stock in the M logo

Thanks! This did work for me. I am now rooted.
I am using twrp 3.0.0.0 I used 2.62 however when I tried to click the option in the terminal keyboard for the = (equal sign) I keep getting a blue screen. 3.0 keyboard works ok. I entered the, echo "SYSTEMLESS=true" > /data/.supersu and pressed the go button. It showed up on the main terminal screen. Im a bit confused at this point....do I flash supersu from my pc using flashboot on the bootloader page? or download the supersu.zip to my phone and use twrp to flash it? When twrp asked to flash supersu I did that and wound up stuck on the big M again. I think I restored my phone about 6 times so far. lol
Flash in recovery. Use 2.62-3.
So using 2.62.3 will void having to type SYSTEMLESS=true" > /data/.supersu. or do u still have to type that in terminal? Plus using the twrp-3.0.2-0-clark. Should I use and older version?
No just flash.
Flashed Supersu 2.76 on top of xt-1575 18-4 image without any problems usung TWRP 3.0.2.
I did add .supersu text file to /data just as an insurance.
Nuts. Didn't see the part about doing a backup first (hitting head, as this isn't my first rodeo). Too anxious I guess. Now I'm stuck at the M android screen. (didn't do the "SYSTEMLESS=true" > /data/.supersu" command). Any way to fix or am I just screwed?
I can get to TWRP, so theoretically, I could flash a stock version of Android back onto it. Anyone know where I can pick one up?
Did the same ****. Was so excited getting the phone and didn't read the systemless =true crap for M. Didn't do a back up but got a system file from Motorola. You can pick one up here to start over. http://forum.xda-developers.com/moto-x-style/development/pure-firmware-tuff-wip-t3224833
Anxiety might lead to unexpected results
Can anyone make and post a video step-by-step on how to do this? Last night I was about to root my new Moto X Pure X1575 (No updates installed, need to freeze the process to avoid making the root process more difficult) and if I rushed I could've made a HUGE mistake. Mine is running Android 6.0 (Marshmallow), was about to use previous and experimental methods but after reading this post I'd rather wait and make sure everything works.
Btw, I got my phone directly from Motorola, added a bit more memory through Moto Maker (32GB), will this make any difference in terms of getting the root access?
Thanks in advance

Not really sure what you need a video for, the process is simple and the same for all Gen3/4 Moto devices... the chanced of "breaking" something are near zero. You need fastboot working, that is on you.
1) Unlock the bootloader
2) Download the latest TWRP and SuperSU. Place TWRP img in your fastboot directory and SuperSU zip on your device so you know where it is, internal storage or SD card is not relevant.
3) Start the bootloader, either with `adb reboot bootloader` or power off and hold VOL DN and then press and hold POWER until the menu comes up
4) Start TWRP with `fastboot boot twrp-3.0.2-0-clark.img` and backup
5) Go to TWRP's Advanced menu and select Terminal
6) Enter `echo SYSTEMLESS=true>>/data/.supersu` press enter , exit, and Home button
7) Install (Flash) SuperSU ZIP file, clear caches if you wish but it isn't necessary.
8) Reboot
That is all there is too it
