How do I manually reroot nexus 7??

Ok every guide I looked at said you can easily flash something to gain root again well in order to flash anything you have to have root so it doesn't make any sense and I didn't see any guides on this or related posts and I'm running 4.2.2

fastboot oem unlock
fastboot flash recovery nameofrecovery.img
boot into recovery
flash the supersu.zip root package.
What is so complicated about that?
you dont need root to flash something, you need an unlocked bootloader and a custom recovery.....
i swear the word root has lost all meaning these days. everyone wants it, but it seems so very few actually understand what it is.

Pretty sure you just need to fastboot flash a custom recovery, then you can flash the superuser binaries by chainsdd (Google the package), then install superuser or superSU from the market.
Not familiar with nexus 7, but this is how I rooted a galaxy nexus. There should be a sticky in your device specific forum with links to the process and files.
From my Evo LTE, yup.

I went to fastboot but when I go into recovery I get an error

thats stock recovery.....did you ever FLASH a custom recovery, like all the guides tell you to?

I tried downloading clockworkmod recovery from ROM manager but the download failed so I downloaded recovery manager from the play store and downloaded a recovery using the app it said the recovery installed

Dude,
As the guides tell you, and I lined out above, you need to FASTBOOT FLASH RECOVERY
unless you are already rooted, then downloading ROM Manager or 'recovery manager' from the app store doesnt do any good....
you need a computer to do this in fastboot mode.

Damn I was hoping I could avoid using my friends very slow comp lol

I'm in the similar situation - I upgraded rooted 4.2.1 via modified OTA (original OTA was failing because of one apk) and now I have 4.2.2, but even though I had SuperSU which was ticked to "survival mode" (should keep the root), it apparently didn't. I don't have TWRP anymore, when I press power+vol dn I get the standard "start" screen (original recovery). Also, when I turn N7 on, it is displaying keychain that is OPEN, that means my bootloader is unlocked?
So my question(s)... my bootloader is probably unlocked? If I do the steps:
fastboot oem unlock
fastboot flash recovery nameofrecovery.img
boot into recovery
flash the supersu.zip root package
will I loose all data/apps? I ask because when I first rooted with toolkit, I lost all apps/data.
Also, where to find supersu.zip ? That is different to the installed SuperSU.apk, right?

Damn I can't make ADB work... I tried 2 computers.... Damn google for making this so [email protected]#[email protected]$ .... Constant problems, nothing else. Any clues? I ofcourse, tried kill-server and start-server, no matter what my device is showing offline....
Just checked with my phone (SGNII) and it is working just fine... no clue why Nexus is showing as offline..

How do I manually re-root 4.3 and update SU binaries?

I was rooted on 4.2.2 and checked for the system update for 4.3. It was there so I got really excited and installed it immediately, without writing a thread about it, making sure I'm not doing something wrong. Well, I was.
It updated to 4.3 and it works fine, but I can't access TWRP (I get an opened Android with a red X over it). Also, when I go into SU, I get a message saying "There is no SU binary installed. ... If you've just upgraded to 4.3, you need to manually re root your device."
How do I do this? Thanks.

Toolkits cannot flash the recovery on Android 4.3 so you have to download the recovery image and flash the recovery image using "fastboot flash recovery [Replace_this_with_image_name]" and enter while your Nexus 4 is on bootloader mode to flash the recovery properly.
Now you need to transfer the SuperSU v1.51 zip file to the root of your internal storage and install it via TWRP recovery and then you are fully rooted without any TB restore issues or anything like that.

Thank you so much, but I don't quite understand the first part since I've only rooted my Nexus 4 once, using a toolkit. I hope you don't mind, I have a few questions: Where do I download the recovery image and where do I type the text you wrote?

I rooted and unlocked my device with a Toolkit but the problem is that you do not know what is exactly going on since you cannot see the commands.
You have to get the Android SDK for this one, I already have it all in a zip file but that is on my laptop and I will be working on my phone today by installing PA.
One you get the SDK you have to go into the SDK manager and download/update the ADB tools, after that open the CMD in the folder which says "Platform-tools" and type the command from there.
Has for the image you have to put it in platform-tools has well for this to work:

Nexus 4 won't boot, only bootloader and CWM

Hey everyone my Nexus 4 was getting a never ending amount of app force close so I restarted my phone and it just stayed at the CyanogenMod boot animation. I tried booting into ClockworkMod to wipe factory reset and got a list of E: mount fails, I assume something to do with the storage?
I decided to revert to stock by using this method: http://forum.xda-developers.com/showthread.php?t=2347060
Nothing happens though, the device restarts in bootloader mode and nothing, the message I get in the program is posted as an attachment.
Is my Nexus 4 fried?

It seemed like it would fix it, but it actually didn't change anything. I searched Google and XDA, that thread would show up as a top result. If someone could point me in the right direction?

1. download the pack here: http://developer.android.com/sdk/index.html put it in an easy to remember location, like on your C: drive on the PC
2. download the factory image from google here: https://developers.google.com/android/nexus/images#occam
u´ll probably want the 4.3 (JWR66Y) - the latest
3. unzip the google image in <your location>\adt-bundle-windows-x86_64-20130729\sdk\platform-tools
4. have your phone in bootloader mode (press power+volume down)
5. run flash-all.bat

Need help on OTA update with Nexus 7 2012 Rooted

Hi,
My Nexus 7 3G 2012 was rooted, stock rom 4.3 but I've deleted some APK in the system partition. Now my Nexus 7 received an OTA update for the KitKat. What is the quickest way to safely update to the 4.4 while maintain all of the installed apps and userdata?
Thanks

1. Download the official KitKat image files from Google
2. Extract system.ing and boot.img from it
3. boot into bootloader
4. fastboot flash system system.img
5. fastboot flash boot boot.img
6. reboot your system

Tks for your reply.
So all data and installed apps will be inact?
Sent from my Nexus 7 using Tapatalk

Yes, I am doing it always in that way, because I have a rooted system and normally there are often problems with applying the OTA. Flashing boot and system will keep your data and apps which are located on the data partition. If you want to be really sure to have a clean system, I would also flash a custom recovery, boot directly into recovery and wipe dalvik-cache, but this is not really needed.
Sent from my Nexus 7 using xda app-developers app

This is interesting and really new to me.
Could you please precise, which tools you use? A little how-to would be very helpfull to get along with the bunch of possibilities coming with TWRP and/or wugfresh´s toolkit.

I am using no tools / toolkits as I want to have full control on the flashing process. Probably you might want to have a look at my blog. Here I described the update process already some time ago (not to go to 4.4, but the steps and the mechanism are the same).
Sent from my Nexus 7 using xda app-developers app

Ok tks for your response.
However my friend confirmed that he updated successfully to 4.4 via OTA while rooted.

I have used this method every update. Only takes about 5 minutes.
It amazes me all the convoluted methods and bricked devices that you see, when if people would do a little research and had a little understanding of what they are doing it would save them a lot of grief.
All I can say is thanks to the person who wrote this simple how-to.
Now I will get off my soap box.

Going from 4.2.2 to 4.4.2

Hi there, I'm currently rooted with 4.2.2 and I want to upgrade to the latest which I believe is 4.4.2, after a brief check I don't see the toolkits supporting this so can someone give me a clue on what to do? Is it upgrade to 4.3 then 4.4 and finally 4.4.2 or can I just jump from my current to 4.4.2?

If your on stock ROM and kernel and recovery just check for updates under about tablet system updates. If your running a custom ROM or kernel then you'll want to get to stock first. Also you can just download the factory image and adb flash it. Just search how to install 4.4,2 factory image with adb on nexus 10. There's plenty of guides.

Just update and root again. It takes a minute using one of the toolkits. Or you can just flash the super su zip which is even quicker if you have a custom recovery. Either way it's easy and quick

I can't use system updates, it won't restart after counting down from 10 it just hangs there. I also don't think the toolkits have 4.4.2, I'm pretty sure I downloaded the right files, I just don't know the commands to use in CMD.

Wugs toolkit has it.
Extract it and put it in the correct folder with Fastboot capabilities and use the commands
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img (this'll give you stock recovery)
fastboot flash userdata userdata.img (only do this one if you want to completely reset and delete everything on your internal SD card. Don't do this step of you want to keep your files like pictures and music on SD card)

Okay, going to try Wugs. Ah, I'm mistaken then, I just have the factory image and update superSU zip files.
See this is what I don't get, it asks me my build, which is 4.2.2. And then asks to download the image, but I want 4.4.2 so do o just change it to that?

Yeah. Choose 4.4.2. Asking your build is just so when you flash kernnel and recoveries it flashes a compatible one. But since your just flashing stock images. Just do that. But again remember it'll wipe everything so backup your SD card to a computer first

If you use Wigs toolkit you can flash the new update if you do a complete restore with in root. Then you can re root. Just go to flash stock + unroot then click the images drop down down box. Pick the mantaray-manta : android 4.4.4- build KOT49H then click the button that shows automatically download. After install re root and restore. Backup everything first it makes a quicker restore.

First, go download the image:
https://developers.google.com/android/nexus/images
While that is downloading, make a new folder on the desktop and name it FLASH, also for extracting the file once it is downloaded I reccomend total commander:
http://www.ghisler.com/download.htm
Also head over to here to download adb and fastboot without the android sdk:
https://docs.google.com/file/d/0B1MWexkzYR_bV2VlaF9UcHVBU00/edit?usp=docslist_api
Once the zip file with adb and fastboot is downloaded extract the files into the FLASH folder. Now that we've done all this the image should be downloaded, extract the contents to the FLASH folder. Now open up command prompt. In command prompt type the following(excluding the quotation marks):
"cd C:\Users\*username*\Desktop\FLASH"
*username* Is the name of the user. Now turn off your device then boot your device into fastboot mode(hold the power+volume up+volume down buttons) once your device is in fastboot mode connect it to your computer. In command prompt type(again excluding quotations):
"fastboot devices"
After that you should see your nexus device in fastboot mode, if you have no important data and don't care about losing everything(me) you can just type this in command prompt(no quotations):
"flash-all"
But if that does not work or you do have important things, type:
"fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img”
