No you can flash without root.

You only need to be rooted in order to use ROM Manager... If you just unlock the bootloader and flash/boot Clockwork, I believe you can flash about anything.

thanks, I think you are right......with Clockwork anything can be flashed...

Having SU and Busybox installed is helpfully with some apps that require root such as titanium backup and root explorer.

Recovery?

Anybody know where to get a recovery that I don't have to flash and don't have to be rooted because my coms down and I can't root it. Z4 doesn't work

If i was to recall, it's not possible to get a custom recovery without rooting it.
You could always use stock recovery if that's what you want? ^^

Well that's just it I don't have a recovery anymore it died (personaly idk what happened to it it just stoped working and froze when I wanted to get to recovery..)

You got to have root or your phone won't let you install a recovery. Once you have root, you can install CWM recovery via the RomManager app (free in Play store) according the the sticky in the dev section...

CWM
Follow the instruction's of that thread then download Rom Manager on your phone & install the recovery for SK4G also then reboot into recovery then reinstall package's . Enjoy .

Note: CWM link in quote above shows you how to get root.

Root

can you root a us wifi xoom running 4.0.4?
Sent from my PG86100 using xda premium

I have seen a similar request about the same before, I remember that the way to do it is to install superuser apk into your xoom to have root access.
or superSU.apk
Will check how and get back to you.

I don't think just installing a apk of
Superuser can get u root access

My bad. I meant superuser package flashable zip
1) get recovery and install it via adb.
2) thru recovery. Flash superuser from here. http://www.4shared.com/zip/g3yzbrIa/su-install.html?cau2=403tNull

How do I install a zip through adb?
Sent from my Xoom using xda premium

I would rather install it through Recovery...
Recovery image through ADB.
Superuser ZIP through Recovery.
Or, use this step by step: it guides you thru the entire process.

[Q] Root/CWM on 4.1.2

Does anyone have a root method and cwm recovery for android 4.1.2 stock? i was so excited when 4.1.2 OTA came out, i updated and now I can find a suitable method? I tried searching for a method, but I couldn't find any. If you could point me in the right direction, i would greatly appreciate it.

Download the superuser to Sd
Download the latest clocworkmod recovery
Reboot phone into bootloader mode
Open a command prompt, go to folder
Now execute this fastboot command to flash the CWM recovery. Change the filename to the file you have downloaded
fastboot flash recovery recovery-clockwork-6.0.1.0-crespo.img
using the vol down key choose to go to recovery
Install zip from sdcard superuser zip file.
Reboot. You now have rooted JB
Basic root method.

Yes of course you need to unlock. I assumed he was. My mistake, I forget the bare basics at times.
Yes that guide works well. Just use a newer Clockworkmod http://www.clockworkmod.com/rommanager
and super user http://androidsu.com/superuser/
The hardest part is PART 1. Many have issues with Device Manager and getting the computer to read your phone properly.
Use this http://junefabrics.com/android/
Use this guide for the drivers if necessary also

A small rooting dilema

Hello everyone, I'm completely new to androids and I recently rooted my phone with CF's Auto Root.
I've been scouring the forum for information on how to resolve my problem but none that really help me with my specific problem
I want to re root with clockwork but can't find anything on it
Can someone help me out here? Sorry for sounding really dumb, I just switched over from apple this stuff is a completely different world to me

Completly factory reset your phone n try rooting again . If it fails, you need to root using the same software as you did earlier

So with my original method I've rerooted my phone. How do I install clockwork mod on a rooted phone if it wasn't installed in the rooting process?

Take a look at the "goo manager " app and TWRP instead of CWM.
But CWM also has an easy install app if your phone is supported. Just see if it is or not and go from there either way.

Thanks for answering Pennycake.
I'm on Rogers Carrier OEM firmware right now and I'd like to flash the international firmware as to rid bloatware to my Note 2.
Which app would you recommend me to backup my rom with?

I've successfully rerooted, I found the problem with my phone. After it had been unrooted it needed to be rebooted in order for some effects to take change. So through the original method of CF-Auto Root, I rerooted my phone. I've installed the standalone ClockWorkMod app but it doesn't seem to make back ups properly. Through the app I hit back up and it shows the time stamp I hit 'ok' and my phone shuts off and starts up in recovery mode only not in ClockWorkMod but Android system recovery <e3> or something along those lines with only options to: reboot, install updates from adb, wipe data, etc.
What am I doing wrong?

Try installing the recovert img using clockworkmod before backups, because its not an app error, it is a user error. Using chainfires root method means no cwm. Using odin or lemme guess, you have a gs3, unified tool kit you get cwm.

What recovery do you have right now? If it's twrp (team win) do that go with clockwork mod. Twrp (goo manager) is by far (in my opinion) the best and user friendly. But it's your call. And you don't have to un root and re root to do it. You just have to flash the new recovery via bootloader and it will work. For rom choices I personally like jedi xpx and jellybam. With jedi xpx you can overclock the sh*t out of your note 2 to 1920 and it's still stable.
I've used many recoveries and twrp is my choice hands down. And yiu make back ups easier. So dont unroot again and re root. Just download the latest twrp and flash through bootloader. but to each their own

I'm on the Galaxy Note 2 i317m in Canada. Clockworkmod isn't letting me back up, everytime I get the box with the timestamp to create a back up I hit 'ok', my phone reboots into recovery mode and its the stock recovery, so no option to restore. Also when my phone's model isn't listed in the clockworkmod flashing menu within the app. Is my phone not supported? The N7100 is the one listed when it asks you do confirm a phone model.

When I boot into recovery it says is Android System Recovery <3e> and below are listed a few options, reboot, wipe cache, install from adb, etc

Then you dont have twrp installed. And by the sound of it you dont have cwm either
