[Q] how to install again superuser? - Nexus 10 Q&A, Help & Troubleshooting

by mistake a deleted the superuser app and I need it again. I installed it from the store but seems broken.
I have the Superuser-3.1.3-arm-signed.zip but seems that I can't flash a zip when i enter in recovery in the nexus like i do in the lg.
I have searched but can find anything helpful. could someone please give me a suggestion on how to flash it without erase everything? can i do it with a computer using the command line?

hope it helps you
You can use a toolkit, it would be a lot easier for you.
Here is a good one Wug's Nexus Root Toolkit v1.8.2

Thanks and great idea. Will try it later

Working like a boss. Thank you once more.

[Q] Which rooting method?

I see a couple of different tools here to unlock and root my Nexus 7. What are the differences between them?
I do not want to flash ROMs; just unlock, root and install cwm recovery.

fastboot oem unlock, fastboot flash cmm recovery, flash the su binaries, reboot and profit.
Search for wugfresh nexus root toolkit. Very simple to use.

Don't use tools for rooting with the Nexus devices, it's useless in my opinion. Try to understand the basics behind rooting, recovery and fastboot, do it manually and you will be able to help yourself even if something is not working as expected.

Even though I know how fastboot, recovery and rooting works, I still use this tool without any of those commands. And it serve the purpose for me quickly. Of course using such tools will not stop you from learning more afterwards.
I wouldn't say its useless.

then you should br helping out all the people that mess up their devices afyer using toolkits and dont know how to fix it. i havent seen you help out, yet you are still recommending toolkits. why is that?
I used the steps outlined at http://rootzwiki.com/topic/28544-guide-nexus-7-bootloadersrecoveriesrootback-to-stock/ to guide me.
I must say it might not be trivial for the non-software-developer types.
I was a Java developer for many years, so I didn't have much problems setting up Java,
Android-sdk, etc.
My N7 was recognized by adb when booted normally, but after I flashed cwm, I could not do 'adb shell' to mount the /system partition and rename the recovery-from-boot.p file to prevent the recovery from getting reset to stock each time.
I ended up installing the ROM Manager app to enable me to boot into cwm recovery.
I have done the obligatory cwm backup. I believe this is the nandroid backup?
Edit:
I used my Linux box to re-flash the bootloader and cwm recovery images to the Nexus 7, and I could 'adb shell' and rename the recovery-from-boot.p file. So I'm all set now.
I just needed to run 'adb start-server' and 'fastboot' using sudo, so it might have been a permissions issue on my Windows box.

I used Wug's Root Toolkit. Both of the toolkits seem good, but that was just the first one I saw. The Wug's Toolkit is an application and the other one is in a CMD.

Absolutely brilliant ToolKit, very simple, fast and works like a charm.
I rooted my N7 with this, and had no issues to date.
Only took a couple of minutes.
BRILLIANT!
Looks like I'm not all set, after all Today, right before I plan to take the JB 4.1.2 OTA update, I notice my tablet won't boot into CWM, like it did a couple of days ago. I did rename the one file and things looked normal. What could have happened to my CWM?
Edit:
So there are 2 files that need to be renamed, not 1?
/system/recovery-from-boot.p
/system/etc/install-recovery.sh
And there was a bug in JB 4.1.1 that prevented booting into cwm recovery unless the device was plugged into USB??
Sent from my Nexus 7 using Tapatalk
I re-flashed the same cwm recovery img, reinstalled the same su zip, and I'm back to normal
Gotta watch out for those OTA updates, I tell ya.
Use the fastboot commands
Good to see you alright!
This is like asking "Should I get an automatic or manual car?"

In the early days, automatic transmissions were more problematic and much more expensive. Today they are pretty efficient, even though a manual transmission gives you better control over the car, which most people don't really need for everyday driving.
If you frequently get stuck in stop-and-go traffic, you'll wish you had an automatic transmission.
Look at these lazy people..

Yes there was a bootloader bug on the nexus 7 and most people could not boot into CWM recovery without plugging it into their computer.
I however used TWRP back then [have since switched back to CWM touch, now that the bug is fixed] and had no issues. Now I have no issues with CWM touch, I can boot it directly from fastboot menu, or "reboot -> recovery" when booted.

exactly what I would have done! sounds like you're getting the hang of it. and yes, I definitely recommend manual rooting/fastbooting to a toolkit.

Yeah, that's what I'm saying. They both have their ups and downs. If you're willing to learn a little about how Android works and learn some adb and fast boot commands then you should definitely do it manually.
If you just want to be a "1337 Haxorz" and aren't willing to learn then just use a toolkit.
OK, just one sub-question on rooting. I see no real reason to root except maybe to get more tablet interface than nexus has. Kinda like when the wifi indicator is at the bottom, since there are those !$#$$ back/home buttons already and a lot of wasted space Anyways, the question.
I bougth N7 16Gb and upgraded via forced OTA to 4.1.2. Do all these root methods work with 4.1.2?
Thanx,
D.

Lost root after 4.2 update. Need help!

Hi guys, I just updated my N7 to 4.2 and I lost root during the process. I made a su backup with Voodoo OTA rootkeeper before I did the install. After the install was complete, went back into voodoo to restore root, rebooted, and did a root check using 3 different apps. Voodoo shows my device rooted and root checker and titanium backup cannot find my root access. Is there something I did wrong, and is there any way to restore root access without a fresh wipe. Thanks in advanced!!!
Try uninstalling your root App and then reinstalling it. You also might want to wipe cache and data for your root App in Apps under Settings. Do this before uninstalling.
If that doesn't work push root to your device using one of the many methods available.

I ran into same problem, if you use Wug Toolkit, make sure you set to "android Anybuild". this Toolkit is not yet updated for 4.2.
There is another Nexus Toolkit by Mark Skippen which was updated to 4.2, however you need to donate to get the latest version. It works well for me
It's woth the donation of Pounds 5 or $8++ something
Good Luck

Need help, rooting nexus 4 with WUGfresh 1.6.1 did not work

i'm completely new to android/nexus 4/ rooting so i used the wugfresh to try to root my nexus 4 since it was supposed to be easy. it was going all good and i unlocked the bootloader and then when i went to root, everything was going good too. however, it did not get passed the twrp menu, it just stayed there and i did not know what to do. so i clicked "reboot system" and when it rebooted it said my nexus4 was rooted but superuser and busybox was not installed. when i ran some apps that needed root to work, they did not work. i tried installing superuser and busybox myself from android google play and it still did not work!
PLEASE HELP

[Q] How to Root Nexus 7

Hi guys. I want to root my nexus 7 (8gb) so I can play music through a usb drive. And I don't want to install any roms or stuff like that, I want it to be exactly how it is now, with android 4.2.1. I've been browsing the forums, but I can't really find instructions on how to do a simple root for my purposes. If anyone could direct me to the steps I need, that would be great!! Thanks!!

simple rooot.. fastboot oem unlock, fastboot flash a custom recovery, flash the super user binaries via your custom recovery, reboot and profit. you either have root or you dont, there arent different kinds of root depending on your needs. i suggest you do a bit more searching and reading, because its impossible not to find instructions if you actually searched for it. of course if not finding it on xda, you can always search the words root and nexus 7 in www.google.com
There are several ways to root your Nexus7, and I think using the toolkit is the easiest.
I'd like to recommend to download this toolkit to your PC.
http://forum.xda-developers.com/showthread.php?t=1809195
With using this toolkit, you can root your device as follows.
1. install the Nexus7 drivers to your PC
2. unlock the bootloader of your Nexus7
(when you unlock the bootloader, all data is deleted.)
3. install custom recovery to your Nexus7 (i recommend TWRP)
4. root your Nexus7
enjoy

Is there a later version of the rootkit? The last image it has is 4.2.1. 4.2.2 is out and I'd imagine on most Nexus-es.

I'm on my last legs

I've been trying to root my nexus for a few days and have had no luck i tried mskips tool kit and get this "rm failed for /system/bin/su no such file or directory" i have tried the [Guide] Ultimate Nexus 4 Root Guide and the win zip i have wont read the recovery-clockwork-6.0.3.1-mako.img says some thing about an iso and ive tried the zedomax youtube video way and my command window doesn't find the nexus root folder if anyone can help me i would appreciate it because i have given up all hope of getting this damn thing rooted
Why are you trying to open the recovery IMG with WinZip???
Step E from the first post in this thread, but read the entire first post to make sure you have the prerequisites, i.e. adb and the drivers, etc...

Could also just flash a custom ROM (most, if not all of them come pre-rooted with no effort). This isn't the first time this has happened either, but it's been a long time since it has happened...

+1 Follow this link wugs toolkit is 2nd2none!!!!!!! The hardest part is making sure the drivers are installed correctly(Just plug in your N4 with Debugging on and checked plug in to your computer and windows should install the ADB drivers). After making sure the ADB drivers are installed and USB debugging is on and checked, you might need to toggle "MTP" to "PTP" for Wugs toolkit to see it. I have an issue with my win7 PC not installing the drivers for MTP I don't know if that will be your case just a heads up. I can pull and push using ADB no problem I just need to check PTP for it to show up under ADB. Search YouTube for "Root Nexus 4 Wugfresh toolkit" GL
