[Q] rooted now not - Nexus 7 Q&A, Help & Troubleshooting

I unlocked then rooted my nexus 7 8GB. Mainly to access external storage. This I achieved and with stickmount was able to achieve the objective, reading from a usb stick.
I felt at the time that there was something wrong as installed app Titanium backup pro - but could never find it. though google still tells me it is installed.
Rom manager states I have ClockworkMod 6.0.1.0 & that 6.0.2.3 is available BUT after dowloading "Flash ClockworkMod Recovery" an error occures.
I installed root checker pro. It advises that not rooted properly although busybox is installed correctly. Reports attached
I have both superuser installed at original root. Since also installed Super su, neither will install binary code.
Is there anything I can do to ensure I am rooted and stay that way?
Thanks for any help offered.

Easiest thing to do boot into recovery, make a backup always,do a wipe flash a custom ROM plenty out there

You may have lost your root, so try to reroot. As for keeping root, DL Voodoo OTA RootKepper from the Play Store. Works like a charm.

OTA with TWRP?

this may have been asked, but i'm new to the nexus 7. i rooted it right away, and put TWRP on. probably shouldn't have but i like doing nandroids. i was excited for the OTA and want to just install it since my tab got it, but it won't obviously since i've got a custom recovery (duh i should've thought of that..) and i don't want to go flashing roms yet (i like keeping everything stock right away, it's so smooth)
so my question is, is there a way to go back and flash the stock recovery somehow so i can OTA, then put TWRP back on? i can't find the stock file to fastboot flash or anything
You can either download the OTA update manually and flash via TWRP. or do a full 4.2 stock ROM
http://forum.xda-developers.com/showthread.php?t=1989158
Warning: there have been mixed results from the early adopters on the OTA patch. I was running 4.1.2, TWRP, and SuperSU. I lost both SuperSU and TWRP when I upgraded and a handfull of apps are not working right with the new multi user file structure.
The way I did it was
1) Download the OTA zip from the thread I posted above
2) Moved that to SD Card (I moved via Google Drive, you can use USB if you want) I did the whole thing while waiting for a flight without a computer handy
3) Reboot to TWRP Recovery
4) Flash OTA Zip
To get Root and TWRP back I did the following (note, I have SuperSU pro and the survival mode was checked)
1) disabled SuperSU and reenabled which prompted to update Binaries
2) flashed TWRP via ROM Toolbox

thanks kangy! i also lost both when i flashed.
the reason it didn't work was that i frogot i played with my build.prop and had apps frozen on titanium.
so i disabled and reenabled SuperSU, but no prompt to update.
i'm using rom toolbox now to install but it keeps telling me install failed...basically because it doesn't have root i presume. any ideas?
Alright try this.
Go to SuperSU settings and and click on Reinstall under Cleanup, it will give you a prompt and tell you it will self close and to re-install from the market. (Mine never fully uninstalled which I assume is due to it being flashed to ROM, I checked under the App manager and it only had a downgrade option so) Anywho. If it did uninstall go ahead and redownload it from the market, if it didn't check the market anyway, the Dev published and update for it to help with 4.2 multi users.
Once you get it reinstalled and/or updated from the market go back to the settings and Toggle off Enable Superuser, close the app, re-open and then re-enable superuser. You probably will want to give it a reboot at this point. (Ive restarted my device a hundred times since going to 4.2 from trying to work through the bugs. Once you restart test a root app. I used Adaway for the test. Important, if the app fails or gives an error about not having root, try again. After I went through all of those motions SuperSU was pretty slow for a while with giving root access, usually the second request from the app wakes it up. Since then though it is back to being snappy with zero lag.
Yes, the reason you can't flash TWRP through ROM Toolbox is that requires root. Once you get your SuperSU working try flashing the latest TWRP again, it should only take a few seconds to flash. Let me know how it goes, I'm subscribed to the thread. I may not be the smartest guy on XDA but you are in the same exact boat I was last night!

First, determine if you have root or not. Open TiBackup, if it opens correctly and you can see all your apps listed, you have root. Otherwise it will say "Failed to obtain root," and quit.
If you have root, then great. If not, you can flash the SuperSU zip in TWRP/CWM: http://download.chainfire.eu/282/SuperSU/CWM-SuperSU-v0.98.zip
I haven't tried flashing superSU, I've always flashed Superuser zip [google "superuser zip"], and then installed superSU from Play store.
Once you have root..
Go to Settings > Security and check allow installation from non-market apps, and uncheck the security feature that checks all apps for being malicious.
Then try it. If you still cannot restore apps, you might have to install them with adb.
I just updated someone's N7 to 4.2, and as usual I backed up everything in TiBackup.
Then I backed up the TitaniumBackup directory [because I had to do a full factory reset].
I then extracted all the .apk.gz files with gunzip. [in linux OR adb: $ gunzip *.apk.gz -- for windows, I suppose you would have to use 7-Zip].
Then I tried to install with pm:
Code:
for i in *.apk; do pm install $i; done
But every one was giving me an error, INSTALL_FAILED_INVALID_URI, I couldn't figure it out. Found a thread said to chmod 755 /data/local, but that did not fix it.
So what I had to do, was on my linux PC:
Code:
for i in *.apk;
do adb install "$i"
done
So I finally was able to batch install my apk files.
after that I restored all apps data.
Nandroid back ups not possible after 4.2 update
After updating my rooted N7 to 4.2 OTA I re-rooted using Wug's Nexus Root Toolkit 1.5.5 and realized that Nandroid back ups are failing.
I had no problem creating such back ups while on 4.1.2 and using his Toolkit 1.5.3. I guess the reason may be that the 1.5.5 Toolkit does not have the latest build incorporated.

why are you even using a toolkit? it's a nexus!...
Root by flashing Superuser zip or superSU zip in CWM/TWRP.
Make nandroid backups in CWM/TWRP, and you should have no problem.

NRTK 1.5.5 would not flash the 4.2 custom rom I fed it either. Just kept stalling out with errors that it could not find the zip file.
So I booted into TWRP and flashed it with no problem at all.
I also did backup in TWRP and checked everything but saw no mention that is was a Nandroid backup. How can I be sure?
i'm trying to nandroid back to a 4.1.2 nandroid i have, problem is, twrp has different directories for nandroids in 4.2 than 4.1.2...so it can't find the old nandroids and i can't find the 4.2 dir where twrp stores them now. ugh. such a damn headache for an update that it turns out i didn't want lol
Read my post below, I was having the same problem but got back on 4.1.2. You have to use the twrp explorer and relocate the twrp files since 4.2 moved them.

Nexus rooting problem

Hi,
I rooted my wifi Nexus 7 using Wugfresh toolkit and everything worked fine. After that I installed SmoothRom 4.3, which again went without a glitch. However, at some point I have noticed that the root is gone. This may have happened when I flashed Trinity kernel, but I am not sure. The Superuser SU is still there and couple of programs still have root access (e.g. Nova launcher), but Titanium backup no longer has root access (and it worked before). I re-rooted this morning using Wugfresh and everything went to the completion. I have Superuser SU and Busybox icons, but Busybox would not install and Titanium backup would not work due to the absence of root access. Any thoughts of what can be done to fix this?
Did you flash with TWRP or CWM? I have heard that you have to re-name some of the file names so that you do not lose the root access. You may have to re-flash and start from scratch but I am not sure. Personally i used MSKIP's toolkit. His has basically a 1.2.3........... root and flash setup. It is very easy to follow, plus one of the steps states "Do you wish to re-name file names so as not to lose Root access on restart." or something pertaining to that, I forgot exactly what it says, but I know that it is there.

I had the same issue. If you reflash the ROM, the problem corrects temporarily. It may be something w/the most recent version of Smooth- particularly when updates are made to Super User. I tried several different kernels and still "lost" root. Eventually I moved on to another ROM and have not had the issue since.
Thanks for the suggestions. I am using CMW. Tried MSKIP toolbox, but same result. Titanium gave back an error message that device appears to be rooted, but Superuser SU is not working properly. So, I went back and did CMW restore from an earlier backup, which seems to have fixed the problem. Titanium is working again.

Unlocked, custom rom and recovery installed on but still no root

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.

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.

Multitool Advance v6 by dr.ketan - Busybox Problem

Hi all,
Just flashing my note 3 to stock rom 4.3 latest update. Then using dr.ketan multitool to root, at this stage all is good. Until I install apps like titanium backup (titanium said no binary found) or triangle away (it says supersu needed, even the phone is rooted and supersu can be updated). Tried to install busybox from apps store but still can't fix the problem. checked with root checker, it says device rooted but no busybox found.
Does anyone know how to fix this issue? Have tried to flash and reflash so many time with different options but still no fix. I just need to get the busybox get recognised so my titanium backup and triangle away can work properly.

Problem with rooting

Hello, I'm having problems with rooting my S4 i9505.
I've rooted it before, but I installed a new stock rom, so I needed to root the new rom too.
I installed custom recovery via ODIN, and that worked fine.
Then I booted into the recovery, and selected SuperSU.zip or whatever it's named, installed that.
When the ROM boots up, it gives SuperSU has stopped working error, and when I update superSU via google play, it gives me error that binaries are not installed.
So what am I doing wrong, and what should I do to root the phone?

If your phone doesn't rooted yet , use the towelroot application it's should root your phone right
You can find an option in the recovery to root your phone. Atleast in Philz there is that option. After that install supersu from the playstore.
I flashed Chainfire-auto root with odin, that worked.
