I got a Google Nexus 4 about a month ago. Somebody told me I should root my phone so I installed the Nexus toolkit and did all of that. I proceeded to install a buncha stuff on it like Call Master, Titanium backup, etc.
But then I kept getting notifications saying there was an update to Android 4.2.2 so I updated it thinking maybe it wouldn't cause a problem. But now none of my programs work, and when I open up SuperSU it says:
"There is no SU binary installed, and SuperSU cannot install it. This is a problem!"
how can I fix this?

Do you have a custom recovery? You'll have to flash the SuperSU zip again so it can install the binaries.

What's a custom recovery exactly? I'm a complete noob to this stuff.
And how do I flash the SuperSU zip again?
Just download the toolkit from WuFresh and in it they have an for Nexus 4 on 4.2.2 proceed to root again since your bootloader should be already unlocked (when the phone boots you see under Google a lock that has been unlocked) once it's rooted again, you'll be clear, I would suggest making a fresh Nandroid after you rooted having the new OTA.

i might try this.
So basically I gotta re-root my phone again? If I do that am I gonna lose everything?
No only unlocking the bootloader will erase your data

Get OTA Root Keeper from the Play Store and back up. Then whenever there is an OTA update, you just restore the back up and you will have root again.

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.

HELP!!! i posted earlier about my rooting problem, still same thing.. when root is accessed it say you have been granted superuser permission for an interactive shell but that process doesnt work.. in my PA the superuser section it doesnt have the superus on it, it says currently no superuser app policies.. me and my friend virtually have the same software on our nexus 4, except only difference is that in his SU on PA has one policy and thats allowing the SU app to work or idk but ill show you the difference.. im thinking i might have to reflash my rom ?
PA already has SuperUser by Koush so I would recommend uninstalling SuperSU or you are going to have root issues.
What is meant by SuperUser app policies is root applications so it is saying that there is no root applications which has requested yet so there is nothing wrong with root.

Okk well i went through the SU app to completely unistall the root but then i had no root.. and the PA root wasnt popping up, so i reflashed the one i had previous, do you think ill have to reflash PA if i uninstall again and still doesnt work? and before i reboot my phone i got to recovery and as i reboot it prompts to intsall root before i reboot so i did it and there was an error when i rebooted
Yep just reflash. Turn off phone, go into the boot loader and go to recovery through there.

I'm having trouble with SuperSU on 4.4.2 on Nexus 4.
So at 4.3 I unrooted first, then OTA'ed to 4.4 and now 4.4.2.
Yesterday I used cf-auto to root my phone, but there was no SuperSU. Then I downloaded one from Google Play. But it keeps saying "unfortunately SuperSU has stopped" when there is a need to use SuperSU, i.g. when there is a root explorer app running. I doubt whether the root was successful so I downloaded a root checker, but it kept saying "please wait". So I even don't know whether my phone is rooted.
Please help.
Do you have a custom recovery? Download the zip in the op and flash in recovery.

no i have the original recovery.
I tried Reinstallation in SuperSU and used root checker, which said my device has root access. But after I installed SuperSU again, it keeps crashing again. (keeps saying SUperUS has stopped.)
If you haven't gotten this squared away, I would recommend using Wug's toolkit to return to stock unrooted and then using the toolkit to reroot.

Just encountered this kind of problem on Purity. Flashed latest build (4.4.2), and then I didn't have root acces anymore. Then I tried rooting with Wug's toolkit (CWM as recovery and SuperSU as root), and unfortunately superSU didn't appear at all in the apps. I tried installing it from the recovery, no luck.
Then I tried it with SuperUser. it worked. I didn't ask any questions
Hi, recently I updated my rooted nexus 4 to 4.4.4 jellybean, which then unrooted it. I still have SuperSU installed, but once I try to run any root apps, it says I am not rooted. Looking around, I need to reroot the device, but my custom recovery TWRP has been uninstalled. I tried to install twrp with GooManager but it wouldn't download. The best option seems to be to reroot the device, but I cannot make a nan droid backup as no recovery installed. I have one but its fairly old, and I will lose a lot of data. What I need is a way to install custom recovery but I'm not rooted :/
You know this is the nexus 10 forum right?
What you need to do is flash a recovery via fastboot and then reroot.

I have a rooted N10, but not running any custom ROM. Have Lollipop 5.0 installed and just got the notice for the 5.1 upgrade. I'm somewhat of a noob to Android, but learning alot. Wondering if doing the OTA would be better than manually installing the upgrade. I'm gonna backup using TWRP no matter what. I want the simplest, most effective way to get the update. Thanks.
You'll likely loose root by applying the OTA, but that maybe the easiest way to upgrade assuming you've not altered or removed any apps from /system/app directory as the OTA does a check before installing. You may also need to re-apply recovery but I doubt it. Assuming you are using TWRP you can use that to gain root again. 5.1.1 has worked flawlessly for me for the last week or so.

Thanks, I wasnt sure if the OTA would install since it was rooted, but if I lose root, I can always root again. I've not removed any apps from system/app. I'll make sure I backup and if i need to recover, I can figure that out.
The OTA threw an error on my rooted N10 and wouldn't install. Stock recovery. I ended-up installing the 5.1.1 factory image in "no-wipe" mode, and everything was successful.
