I am a noob and had someone else install supersu root a few months ago because I dunno how to do it. I just upgraded to android 4.1.2 which uninstalled supersu, busybox etc. How do I reinstall root?
Get Wugfresh Nexus Root Toolkit 1.5.4 (if you have a Windows PC). It does it all for you with a nice easy on-screen menu.

I tried using Nexus toolkit 1.5.4 to re-root after OTA 4.1.2 and it failed to root, it won't even install BusyBox even though it says its successful. Not sure how to get root back without a nuke and pave.
I'm sure the 4.1.2 root problem has been fixed for the nexus 7, and I don't wanna seem snobby, but the site's search function isn't the most helpful for me and all Google does is just give me results to threads of users having the same problem. does anyone have the link to the thread I need to re-root my nexus 7?
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

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.

Nandroid Downgrade from 4.2 to 4.1.2
Sent from my Nexus 7 using Tapatalk 2
My N4 was on 4.2.1 and I managed to root it using the video guide here (http://www.youtube.com/watch?v=sV355YEDzc8&list=FLym1yJ2TTTjBZbty0DrqsKQ&index=3). It worked fine and I was using Titanium Backup with root access.
Then my phone notified me of the 4.2.2 update so I installed it OTA. I thought I still had root because SuperSU was still there. However, when I load Titanium Backup it says:
"Sorry, I could not acquire root privileges. This application will *not* work! Please verify that your ROM is rooted, and try again. This attempt was made using the /system/xbin/su" command"
I then installed a Root Checker (https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck&feature=nav_result) which indicates "This device does not have proper root access".
My questions are
How do I regain root access in a way that doesn't cause a full wipe of my data?
Will I have to do this every time I apply an official Nexus update?
What is the best way to apply an official Nexus update maintaining root without having data wiped?
TIA
I personally use the toolkit and option four. Every time I install an update, I lose root, but the toolkit easily restores it each time.

I too lost my root when i got 4.2.2 OTA. I used WugFresh's toolkit and rerooted with it. I also flashed the CWM custom recovery, which I've read prompts you to keep your root after rebooting with an OTA update.

If you have cwm and you install any update that breaks root it will ask of you want to keep root when you choose to reboot the nexus 4.

This must be about the 100th time someone posts this question.
Some of you clearly are too lazy to search or read
Read this: http://forum.xda-developers.com/showthread.php?t=2145848.
So I updated my tab because there was an incremental update. I lost root and twrp after that, so I used wugs toolkit flash twrp and root my device. My question is, the process installed busybox and whenever I install it (coz wug said so during the process) the binaries do not seem to be found as it continuously nags me to update when I already did so. Also, it doesn't seem to be installed on system/xbin. Need help
I have CWM installed, but I am running stock, no root. I got the 5.0.2 update today and told it to apply. Didn't pay close enough attention on reboot, was asked something about applying something in recover and don't remember if I said yes or no, then prompted for adding root (both of those were in CWM Recovery) and I know I said no to root. After the reboot I was still running 4.4.4.
So I guess I am ready to just manually download and install. Can anyone help me make sure which thread I should be looking at for instructions? I just feel like I have looked at everything and am not confident I am doing the right things. Can I just download the image linked in the Stock OTA URLs thread, then install from recovery?
Installed CWM without Root? :/
