Rooting Permission - Samsung Galaxy Nexus

Hello!
I am currently encountering the rooting permission issue on superSU. When I try to update the SU Binary, it keeps failing.
Also, is there anyway I can flash CWM? I am kinda stuck as I updated a ROM and I am kinda stuck with a fail rooting permission and a broken CWM recovery.
Please help! Thanks!

You can install ROM Manager from the Play Store and it has the option to flash CWM recovery.

No root acess after installing superuser

So I followed this: http://forum.xda-developers.com/showthread.php?t=1514434 and installed superuser and then rebooted my phone. I tried using titanium backup and it says it doesn't have root access. I tried other apps that needed root access and they all said the same. If I have superuser installed, shouldn't I be rooted. What did I do wrong?
You install busy box?

Yeah I did, it says, "BusyBox Installer was not allowed root access!"
Try using the stickied (sticky'd?) root guide. It has version 3.0.5 of superuser. I had to use this version and then update via the superuser app.
Wipe cache and dalvik and then flash su

I would just Odin the stock ROM and start all over at this point if I was you. You may have trashed up the system at this point trying to do other stuff.

Alright I figured out my problem. The posted superuser zip was for android 1.6 devices. I found the correct zip and root works. Thanks guys!

[Q] Lost root

Ok so the story goes like this:
I have stockorama V2
Stock kernel
I was trying to install busybox with busybox installer from the play store, but it said I didn't have root access
So I went to superSU and did the uninstall from the app itself
Rebooted, installed superSU from play store, it told me to update su binary. Then it failed.
when I try to open SuperSU it says that "I don't have su binary... ...that's a problem" and then closes the app
I think I lost root, but I was wondering is there anyway to get it back without a PC.
I still got twrp recovery so I can still flash stuff

You can flash SuperSU via recovery using the link in my signature. Stockorama includes busybox. Don't install it.

That's weird.
You did flash in recovery correct? Cwm or twrp? What version?
Not sure if its any different than Aerowinders, but you can try SuperSU linked in my sig. Or use Superuser, you should find both there.

Flash it in twrp 2.5 I think, did it 2 times... same thing
Its weird because I still get a toast (when I bootup) that lightflow gets superuser permisions; but when I open Titaniumbkp it gets stuck on a message "asking for root rights"
Btw superSU is as a system app so I can't uninstall before flashing the supersu.zip you guys gave me.

My zip came directly from Chainfire's website, I just changed the name.
You don't uninstall, just flash over the old one. And wipe the data for it also.

Nothing... I get the same message.
Flashed zip in twrp, wiped cache and dalvik, fix permissions, reboot.
Open supersu, and get the same message
I'm juat thinking reflash the rom the thing is I wanted to backup app+data with Titanium but no root. So any suggestion to a backup app that backups data without root...

Well, make a nandroid backup just in case. I dont suggest using it as it may just bring back the problem. But you will at least have everything backed up if you need it later.
Aside from that, you can use the recoveries built in file manager. Also you could boot into recovery and then try to ADB pull what ever you need.
But I would reflash your rom. You only need to wipe dalvik if it is the same rom you are using now. But if that doesnt fix it you will need to do a factory reset at that point.

[Q] Used Wugs NRT to root but it didn't quite work

I followed all the steps, from unlocking the bootloader to rooting the device, and flashing a custom recovery. However, when I open SuperSU, it says "There is no SU binary installed, and SuperSU cannot install it. This is a problem! If you just upgraded to Android 4.3, you need to manually re-root - consult the relevant forums for your device!"
Does anyone know how to fix this?

Just get the SuperSU zip, boot in recovery and flash it.
Or you can flash the binaries with adb.

Thanks, it worked!
Edit- Do I need to update SuperSU to flash another ROM?

No, SuperSU it's just an app it won't affect the process of flashing another ROM.

Pls explain what do you mean "no CWM anymore"?
Do you see the stock recovery?
You still could flash CWM or TWRP (another recovery, my favorite I'd say) from ODIN. You need a PC with Windows XP/7/8 and Samsung USB drivers installed to do it. Instructions are available in Q&A.
I initially had cwm installed and my root was working fine.
After I got the 4.3 update via CyanogenMod I updated my phone.
It went well. But I realized that i had lost my root options so whenever I opened super su it said that there's no binary installed and that I'll have to re root again.
So I was like maybe I should just root it again with the method I used first too root my phone ( when it was running on stock ). So I used the same Odin and rooted it. Although it said it was successful the root was still unavailable.
Well I lost interest in that and I got a another update from cm and when I tried to install it I couldnt. My cwm had gone. I tried re installing it with ROM manager but it wouldn't work... I don't know what to do.
