When I open up superSU, it says:

There is no SU binary installed, and super SU cannot install it.
If you just upgraded to android 4.3, you need to manually re-root.


If I turn the Nexus on in recovery mode, it still says it's unlocked.
So at this point, is there anything I can do to restore root status without factory resetting? I made a backup with titanium backup but it was a while ago so I would rather not use it if there is another way.
I've read somewhere that rooting it should mean OTA updates should no longer work but somehow, it still went through and I updated it without thinking too much.

Download the supersu zip file and flash it in recovery.

This will throw me back into rooted mode while keeping my phone as is?

this will update the binaries and restore root. no data will be lost or formatted. simply flash the zip in twrp or cwm.

I don't have twrp or cwm installed yet. Which one is generally simpler/easier to install/use?

So I installed goomanager and tried to install twrp, but it all goes back to the same problem which was that I am now not in root mode anymore.

Also what do you mean by flashing the zip? Which options am I supposed to use?

I've been using TWRP with no problem and it's been awhile since I've used CWM. I've never used a toolkit or flashify but with adb it would probably take a couple minutes max to flash either one.

Choose "Install" in recovery, with either TWRP or CWM is flashing the zip.

Problem is, I didn't install twrp when I had root access before, and now when I try to use it, it says I need root to use it.

Can I flash the zip using adb in the fastboot recovery menu?

What should I do from here?

Sorry I've never done that. I guess you could adb push superuser.apk to the system but you still need the binary wherever that goes. Honestly I would just flash TWRP using adb and use TWRP to flash the SuperSu zip.

Do you have adb already working?

Not yet, I just saw it as an option while reading around.

How would I install twrp with that image file?
All tutorials I've found said I needed root to install it in the first place.

No.You do not need root to install a custom recovery. You need an unlocked bootloader. How did you get root in the first place? You must have used a toolkit of some kind? Use it again? I've only every used adb so I can't help with any toolkits but lots of people use them, I guess!

Download the latest TWRP or CWM recovery. Put it in the same folder as your adb and fastboot files. Open a command prompt and type adb reboot bootloader(you have to make sure developer settings are enabled and USB debugging is checked). Then flash recovery using fastboot by typing fastboot flash recovery name_of_file.img and then you can flash the supersu zip file.

Exactly! I'm thinking he doesn't have adb setup yet.

This is a pretty decent video on how to setup adb, not the newest video out there probably but it should work!

I used chainfires autocf root file from here
http://xdaforums.com/showthread.php?t=2507211

and followed a youtube tutorial.


When I try adb devices it shows my serial number followed by sideload.
I've tried sideloading both twrp and the superSU.zip, and they fail to verify and the installation aborts =\
