[Q] Unrooting the Atrix with stock room - Atrix 4G Q&A, Help & Troubleshooting

Hello,
I have european (or international) Atrix without branding.
I want to root my phone (only root; I am not planning to install any custom ROMs). I am planning to root the device using Pete's Motorola Root Tools.
But because my phone is still on warranty I want to have possibility to return to the stock setting (ROM without root).
How is the best solution to do this?
1. Maybe is there application which could save my current ROM image (without root) and which could in the future restore my original saved ROM (without root)?
If yes, which application you recommend and which is the safest to use? I think that it will require to unlock device but I think that unlocking irreversible voids warranty?
or
2. Maybe is there application to unroot the device without necessity of flashing it?
Thanks in advance

Rooting Questions

Hi,
I have an LG Optimus One P500 and would like to root it. However, I spent all my cash on it and I wouldn't want to brick it or VOID THE WARRANTY. I need a method of rooting my Optimus that will not void my warranty, preferably a one click root app or something.
Please help me.
Thanks.
If your phone came with android 2.2.1 or 2.2.2 onboard, then rooting first involves downgrading the firmware to 2.2. This process has the most chances of bricking your device. There is no concrete way of ensuring that bricking does not happen, though if you follow the instructions correctly, you will in all probability have no problems as lots of people have sucessfully completed the instructions.
You can chose to root your phone using a one click app like 'z4root'. Since there is an option to unroot your phone,you wont void your warranty.
You can even restore the phone to factory state even after installing a Custom recovery or Custom ROM by installing Original Firmware provided by LG using the same procedure used to downgrade yourr firmeware. This will remove all the traces of your fiddling with the phone and thus will preserve warranty.

Rooting and unrooting without custom recovery and official rom

Hello,
I have T-mobile move balance(Huawei U8600). This phone doesn't have any official roms(stock, nor update), and doesn't have custom roms/recoveries.
There is a way to root it through 1 clickroot, but i want to have the option to unroot it if i need because of warranty.
Is it possible?

[Q] Backing up and rooting/unlocking bootloader question.

Hey all, I'm looking to eventually install CyanogenMod 10.1 on my verizon galaxy S4. However, being a complete novice on this type of thing makes me a bit nervous about bricking my expensive phone.
So, I thought it would be good to try and understand the process of rooting and installing the custom rom. Could you guys help me out? I'll list what I know.
First thing I want to do is backup the Android stock rom that came with the phone. I have read that rooting or installing a custom rom (like CM) will void my warranty, so that's not good. But re-flashing the stock android that came with the phone will remedy this. To do this, I found this guide on using Nandroid. I don't think the CWM way will work for Verizon galaxy S4 (read that somewhere, but correct me if that's wrong).
However, it says that I am required to have a rooted phone first before running Nandroid.
Because Verizon's Galaxy S4 comes with a locked bootloader, and an unrooted phone, I need a way to root my phone. I found this nifty all-in-one tool by bhp090808.
The way that tool works is it exploits something in verizon's pre-release kernel of the S4, so it flashes the phone with the pre-release kernel, gets root privileges, then reflashes the stock kernel. Once this is done, my phone will be rooted and I assume I can use Nandroid to backup the stock android on the phone.
This is where I'm stuck. I have a few questions regarding various parts from here on:
1) Since the phone is rooted and I run Nandroid to back up the stock android rom, wouldn't Nandroid back up the stock android rom with the root access? If I needed to return my phone to Verizon under warranty, re-flashing this stock rom would still void my warranty because it still has root access? Is there a way to completely revert to stock android with verizon's unrooted and locked bootloader status (and whatever else)?
2) Does the all-in-one tool unlock bootloader? I found a tool called loki which will unlock the bootloader so that I can install custom roms like CyanogenMod. I looked in the all-in-one tool's zip folder, and it contains a file called "loki_flash", but I am unsure if this is unlocking the bootloader or not.
3) Can I re-flash a stock android if I brick my phone? What exactly does 'bricking' the phone mean?

I see its been a few days and no one has replied so I will do my best to share what knowledge I have. I've been heavily flashing custom ROMs on my ASUS tablet now for the better part of a year and just got my Verizon GS4, so I have alot of the same questions as you.
1) I'm going to answer this in two parts.
​Nandroid, in my experience, refers to the type of backup, not necessarily the process by which to backup. Most common recoveries, including ClockworkMod and TWRP have a feature to create a 'nandroid backup'. This can take some time and files can be quite large, as they copy pretty much every single file on your device; almost like creating a snapshot of your device in that moment in time.
​To answer the later part of this question, (typically speaking) once you unlock a bootloader you cannot re-lock it, but that could be different for phones (my knowledge in phones is limited). And yes, using a nandroid backup will back up your device with root access, but using a tool such as Rom Toolbox, you can easily un-root (the program features a 'permanent unroot option'). For one, I would imagine that flashing the stock kernel would overwrite the root, as like you said earlier in the post the current root exploit works by flashing a pre-release kernel, applying root to the device, then re-flashing the current stock kernel. Another way to lose root is to get an over-the-air (OTA) update. You will see programs like OTA Rootkeeper that work to circumvent this, but in your case that may be a valid way to cover your arse in case you need to return it under VZW warranty (it is for this reason that I always buy Best Buy protection plans, because they could care less about the software state about your device [Disclaimer: I worked for Geek Squad so I have /somewhat/ intimate knowledge in this matter])
2) I just rooted my GS4 a few days ago, and nothing I read indicated that the all-in-one tool would unlock the bootloader. If you read the documentation about Loki, he explains this fact. I just found a good video (although it uses TWRP and GooManager instead of ROMManager and CWM) explaining that there isn't a bootloader "unlock" just yet; rather its a workaround to the bootloader that allows us to get custom ROMs on our devices (video is here)
3) "Bricking" a device means rendering the device useless; it won't operate to any fashion that it is useful to you, so its no better than a brick or a paper weight, etc. I would imagine you can re-flash a stock verizon ROM/kernel to restore any screw-ups, but keep in mind this device was released less than three months ago and any development is relatively new. Yes, we have had other Galaxy S series phones, but the S4 has this whole KNOX nonsense that is specifically designed to prevent the kinds of activities we do here on this forum
I really hope that helps. If I said anything that is incorrect, please please feel free to correct it so that at least we can all learn the proper information.
Thanks,

The S4 link in my signature has a few stock images to pick from. It will restore it to the original stock Verizon software that came with your phone.

Does the 'Ad-Free' APK I see available on that website work better than jRummy's AdBlocker? I installed it and it detects ads (like in ASTRO, Zedge, and a few others) but doesn't block them even though I have all the settings turned ON and have rebooted when requested.
That said, thanks for the link. I've bookmarked it for future reference and its good to know there are backups available in case anything goes bad.
Are you able to elaborate on how these are flashed? Via ODIN, or can you flash it via CWM/TWRP?
Thanks,

I'm not n sure. It's the only one I ever used for banner blocking. You use the files with Odin as well after they are extracted.

how to root i9205 on UCNA2 firmware?

hi, i have a simple question, is it possible to root my device? i've never root my mega 6.3 since i bought it...... but i heard that the recent firmware have some problems in the possibility of rooting it.
there are a lots of guide but everyone say a different method. OK I AM A NOOB OF MODDING.
but is quite difficult to understand guides that are different in this way:
1) some indicates to just use an apk autorooting the device
2) some do require to change thekernel + manually install the superuser apk
3)not permanent root....
4) others......
so, please be patient......:angel: i only want to find a "normal" root method.......and IF POSSIBLE a root that could allow me to easily UNroot the device to be able to update my firmware OTA in the moment samsung will update our great device to kitkat
If you are a noob at modding don't even bother with rooting. Its dangerous and BTW I think your firmware has KNOX which the GMega doesn't have a workaround.

If you are brave enough you can try it using this tutorial
http://forum.xda-developers.com/showthread.php?t=2574953
But read it thoroughly and if you do not understand one thing though - do not attempt to try.
Read forums and learn till you can understand what you are doing lest you have quite expensive paperweight... I am not responsible for what you do with your phone!
my previous phone was rooter, the optimus 3d and the ascend mate.
i don't need toor for extreme modding but just to install a custom recovery for a nandroid backup and for use SOME APP THAT REQUIRE root to work properly.
i never installed a recovery but i read everywhere that it is a lot usefull in case of some errors, to restore the previous backup made 1:1 (nandroid)
Every modding attempt must start from root and (optionally) custom recovery. In fact - rooting itself is modding and quite heavy from system point of view. If you want to change ONE THING in system, you have to root your phone. Doing this you are tripping 'warranty flag' and from now on your warranty is void.
If you have firmware with KNOX and new bootloader - tripping this flag is irreversible. But as long as you do not attempt to flash older firmware (before KNOX) it does not affect the operation of the system. Trying to flash older firmware makes your phone softbrick because of tripping security mechanism in new bootloader.
If you already rooted your phone it is resonable to flash custom recovery and by this have wide possiblity making backups of your whole system (nandroid backup) or flashing custom ROMs
