Rooting without flashing?

This probably a dumb question but I haven't been able to find the answer by searching and reading through numerous threads.
Is there a way to root without having to flash an image? I don't want to have to set up my phone again and would just prefer to root so I can get rid of all the bloat.
Heck, I'd probably unroot afterwards because I'm perfectly happy with everything else. I just want to get rid of NFS and all the other apps that I never use.

Yes, you can with keeping stock just to remove stuff.

Step 8. Hit Start and let ODIN flash the custom CWM Recovery. When it’s done, your Galaxy Note 2 will reboot and you should have a fully rooted Galaxy Note 2.
So this doesn't wipe the phone? I saw this method but am hesitant to try it because I don't want to lose all my data.

Can anyone who has done it confirm? Alternatively could try How to root T889 +Counter reset + Unroot+stock firmware which was posted 3 weeks later in dev ( T-Mobile Galaxy Note II Android Development ) without Max YouTube video within instructions however

I have used that method from galaxynote2root.com and had no problems. the only thing it did was install superuser and give root access, did not touch phone data.

Thanks for confirming

+1 on that method..I did this as well to set up hotspot tethering and it works..no data wipe..
First time doing this odin method so my question is
1. Will I get future OTA updates? It says my phone is modified. Will triangle away fix this?
2. What do I need to do now if I want to flash a custom rom? Install cwm flash recovery and rom as per normal?

Hey if that's really all you want to do, ICS and newer Android allows you to disable bloatware apps such as NFS. Just go into your application manager, swipe to the right until you get to "All" find the apps you don't want and hit "disable" and Tadda! :good:

Even though this requires flashing through odin, this is the best method. No "Modified" status and will not wipe your data. Your phone will be rooted and all settings and apps stay intact (you need to confirm this in the thread).

Won't brick phone, but you will lose root. There are ways around this... root keeping apps. But if you want to know the best way around it, flash a custom ROM.

What is an easy method to completely unroot my phone?

Full unroot in supersu. Note that if your system status says modified, you cannot get the ota.
Its honestly not worth the trouble imo. We could all be enjoying the next update for a whole month before you ever get it via ota. Just wait till its released and Odin flash the new firmware.

[Q] Root/Downgrade to 4.1.1

I just bought a used Note 2 yesterday and am looking to root it. It is completely stock 4.1.2 right now. I am looking to downgrade to the root injected 4.1.1 so I can access the hidden menu to unlock it for other carriers. 4.1.2 doesn't have the right options in the menu to achieve that.
With that being said, I just want to be sure, being COMPLETELY stock 4.1.2 right now like I am; I can flash the root injected stock 4.1.1 ROM via odin with no issues? I don't need root PRIOR to flashing 4.1.1 by doing the CF Auto Root? Thanks a lot in advance.

I believe a similar question like yours has been asked already in this section...

[Q] Galaxy S3 downgrade from android 4.3 to 4.1.2

I have a T-Mobile Samsung Galaxy S3 (SGH-T999) and I made the mistake of allowing an upgrade??? to android 4.3 which has been very unstable for me. T-Mobile, Samsung, and Google all say that there are no updates to 4.3 and I can’t downgrade, so basically I’m out of luck.
Can I downgrade 4.3 to 4.1.2 without bricking my phone and hopefully without voiding my warranty? If so, please give me some instructions. I downloaded Odin 3.07 and firmware: root66_TMO_T999UVDMD5.7z. Thanks a million.

I don't think it's possible to downgrade anymore due to Knox. There was a thread talking about it
Maybe you should check it out.

if you flash the root66 of the md5 firmware via odin after you have already upgraded to 4.3 you will HARD BRICK your phone. Taking the 4.3 ota updates your bootloader and flashing anything other than 4.3 in odin will wreck your life.
You need to download the root66mjc firmware here:
http://www.androidfilehost.com/?fid=23212708291682181
And flash it in odin. Then from there install a custom recovery and download a rom of your choosing and the compatible modem. I recommend you download the md5 modem. Then you're gonna wanna boot into recovery and flash the rom and the modem only (kernels are ok of course) JUST NO BOOTLOADERS. I don't even know if you can do that in recovery but trying to mess with the new BL will brick your face I mean phone.

full steps?
so does anyone have any full list of steps and links on where to get the modems and all to downgrade 4.3 with knox down to 4.1.2

I was referring to the 3 persons who responded to the OP's question similar to yours. @jtl_777's response is pointing to the 4.3 Firmware.

Its more implied in this thread than stated matter of factly. This thread is several months old, and I know your question has been asked countless times in many different threads, much more recently than in this one.
I suggest you read the stickies in each section. Just by doing that you will find all firmware and modems and more. You will also find that the answer is no, you cannot downgrade your full firmware from 4.3. And you never will be able to.
If your having problems I suggest flashing the latest 4.3 build via Odin, then factory resetting. Start over clean with minimal restoring of backups (only the essentials).
Every time an update comes out there are people who have problems. The majority are solved by doing what I just said because most bugs are caused by using old data created by old apps on the new build.
Even if you could downgrade, chances are youd run into even more issues and still have to factory reset.

thanks but I read online and some youtube videos showing that people have gone from 4.3 back to 4.1.2, just trying to make the phone the way it was before any updates were done and wondering if anyone knows the proper steps without bricking the phone.

They probably just flashed a rom. It is simply not possible to downgrade the firmware though.

so i found this post: http://forum.xda-developers.com/showpost.php?p=48758977&postcount=1412 and i have the same case as Christopher4tw with a stock 4.3 T999UVUEMJC and just want to get back to T999UVDMD5 so its running the 4.1.2 version of android
so do i just download the below file, extract and flash via odin then do a wipe via recovery? If not can you please explain how to go about this so i can have 4.1.2 running on the phone
April 2013 - 4.1.2 JellyBean

Flash an older rom with cwm or twrp if you need to be running md5

so can I use this http://forum.xda-developers.com/showthread.php?t=2276645 and flash via cwm or twrp recovery and it will make the phone run 4.1.2 without bricking or having issues with knox or does that have the bootloader issue with it as well?

Yes, that one you can flash.

great thanks so much for your help, can I flash the recovery via odin mobile app or is it safer to do it via pc?

Safer via PC.
It is possible via Mobile Odin. But that's one of the partitions I don't want to mess with when Phone is Booted/

If you know how to use Mobile Odin then it should be fine. I agree that its better to use pc odin if youre not familiar with Mobile Odin. However, it actually doesnt flash the recovery while booted. It flashes the flash kernel which is MO's temp recovery. It then boots to this and flashes. (So, perseus is right in that regard. But I personally love Mobile Odin and find it extremely useful and consider it safe unless you are brand new to all of this).
In fact Mobile Odin is another way you can flash 4.1.2. Itll flash the firmware, but only the system, kernel, recovery and modem. (I didnt bring this up previously because I didnt want to confuse, or go too far too fast).
If youre thinking about flashing recovery via MO, though, you can also instead just flash the rom you found. No need to flash the recovery unless you just want to. Put the rom in the update.zip slot and itll flash just fine.
If any of this is confusing, just stick with the original plan for now. The rest will come easy if you dont rush things.
One more thing, while you can usually update stock without wiping, you may find you have to factory reset after downgrading as the old system was not built for using data created on a new version.

thanks for all the help.. had to do the wipe since it kept showing the samsung logo but after that it booted just fine.

I have tried so many times to downgrade to 4.1.2 using odin but I havent be able to. I always get an error message

[Q] Upgrade rooted s3 OTA

So I have android 4.1.2 installed on my SGH-T999 phone. I used triangle away to reset the counter. Now the OTA can work. Im just wondering will it mess my device up if I update through OTA as rooted?

Is your status official or custom?

It shouldn't mess anything up, but you will most likely lose root. Either way I highly recommend to back up important data in case something goes wrong

I would also point out you have other options too. Personally, I don't like ota's at all. I've seen too many problems with them. IMO, the best and safest way to update is to flash the firmware in Odin.
