Can an Unrooted phone be rooted again? - Android Q&A, Help & Troubleshooting

Hi Friends,
Is it as easy as it sounds? Thanks in advance!

Depends on the phone and how/why it was unrooted in the first place.

Hi, Thanks for you reply. It would be because an app doesn´t support rooted devices and just decided to go back and wanted to know if in the future it was possible to root back. Its for a friend. Can the unrooting and rooting again be done with only those apps used to root your phone or do you have to use a PC?

A bit more info would be useful (device, software, etc.). A phone can typically be rooted again, unless it receives a software update that patches the exploit. Also, the root method may vary, but if you had to use a PC to root it originally, chances are you'll need to use a PC again.

Hi,
I have a Galaxy S3 with Android 4.4. oh I see, if you root in originally with pc and then unroot it forwhatever reason, those one click rooting apps are not going to work right?

[Q] Root method for gingerbread?

So, I am new to this site and to the android community. I apologize if I sound stupid to any of you but if you aren't going to help I'd appreciate it if you just ignored me.
Anyway, I got my Atrix a couple days ago on AT&T and started learning about rooting and such. Everything on it is still stock, last night I upgraded to Gingerbread from Froyo and I'd just like to know if there's any specific rooting program, method I can use right now for 4.5.91 Also, when I upgraded I lost my music player widget, is there I can get it back without going back to Froyo?
Follow the procedure in the second link in my signature. Since you had root before you updated go into settings manage applications clear app data for superuser.

I've read that gingerbreak doesn't work with this version. I'll look it up though.

cool, just one question. Am I supposed to have the device connected to my computer the whole time? and if not between which steps should I connect/ disconnect it? also, when I put the root.img in the C: folder, do I put the zip file or just the .img inside of it?

If you are just trying to "root" your phone only, YES, this is the best method.
Thanks for posting this and providing the link in your signature. I was crapping myself reading the other post about how the new updates bricks your phone but no one said if you are just looking to root your stock OTA's you'll be fine. So, thanks again. They should sticky this under "If you are just running stock and want to root without unlocked BL/pudding use this"

Hi all,
Renaissance613, can you post if you had success and if you ran into any problems? I have the same setup as you (2.3.4/4.5.91) and I'm nervous about rooting so soon after the update (I just installed it).
Also, I'm wondering if I will have to undo this root when another automatic update gets pushed down, or if it will just unroot like my gingerbreak root did. I don't have/intend to use any ROMs. I like stock phone with phone-pulled updates and rooted.
In any case, thanks for the link phobos512 - and thanks to this community of developers and users. You guys are awesome.

I'm about to try it but I'm still confused about a few things like when exactly to connect or disconnect my phone and what to do after I've entered all the commands on my computer, will it install by itself? This is my first time rooting a phone, and my first time even owning an android so I want to make sure I know exactly what I'm doing
I hear you man, it's nerve wracking to worry that you're going to brick your phone. I did the gingerbreak on the last release and it worked perfectly. I'm sure this method will work fine as well, as you said I just want to be sure I'm doing the right thing for my goal: stock phone/downloaded updates/rooted. Best of luck, and thanks to anyone who gives us noobs some more reassurance.
this is by far the best method to root on gingerbread, but i dont see any reason to root but to only flash custom roms, i only needed root pre-GB to allow non market apps, and the new GB OTA UPDATE allows non market apps, so im pretty happy with wat i got, before i updated to the OTA GB i had BL unlocked and rooted, just flashed back to 1.2.6 to be rid of root and unlocked BL, then just went throught the OTA updates to get to GB and im loving it, dont really care to flash any other custom roms, BUT BEWARE DOING THE OTA TO GB AND UNLOCKING THE BL THEN TRYIN TO FLASH BACK TO A STOCK ROM WILL HARD BRICK SO DO YOUR RESEARCH so if u dont want a hard bricked phone dont do the ota stick to custom roms and ignore all OTA'S
so I got through the fastboot reboot command, phone booted back up automatically, then put the phone into debug. Then typed in the adb shell code and said the specified path could not be found.
Now I was still in the command prompt that said the c:/root
What did I do wrong?
So, adb says it is a bad path?? Do this instead..it is easier and it works -- I did it this way last night!
After "moto-fastboot reboot", once your phone has completely rebooted, go to the Android Market and download and install "Terminal Emulator." Once it is instslled and you have opened it, enter the EXACT SAME commands that you were going to type into the Adb Shell..once again, type in the commands VERBATIM. After the last command, there should be a message saying (in terminal emulator) that it was successful! Congrats, you have achieved root access on the AT&T issued stock Gingerbread 2.3.4 build! I hope it works for you!

I'm very vanilla. I root pretty much entirely for free wireless tethering and being able to delete bloatware.
Hello everyone, I am still a little confused between what will or what will not brick my phone. I appreciate your responses.
I am still in froyo 2.2.2 (firmware 1.8.3), rooted using GladRoot method (rooted in previous firmware, then upgraded to 1.83 and used the AfterUpdate.bat.
I am afraid to do the updrade to GB because after reading a looot of threads here on this I am completely confused on what will brick my atrix and what not. If I upgrade to GB OTA, will that brick my phone? if it doesn't brick it, what does? if I upgrade to GB OTA will I able to root it? what method should I use?
thanks a lot

Updating to GB won't brick your phone. After updating to GB you can't down grade to older OS (like the one your on right now) that would brick your phone. So as long as you don't plan on going back to a past OS version (and I don't know why anyone would) you'll have no problems at all. As for Rooting >follow this link< and follow the instructions there after you update to GB. It works perfectly, you don't have to unlock your BL or anything else like that to just have Root on GB. Hope this helps.
Thanks!!! That was the response I was looking for
Now, what method should I use if I were planning to unlock the bootloader?
Also, if something goes wrong and I need to reinstall the upgrade (or better, flash with GB again with a spf file) will that not brick by atrix either?

I9200 root after been rooted and updated firmware???

Hi folks,
Ive been having a strange problem with a couple Galaxy Mega I9200. I have rooted both before without any problems using KINGO originally. The i decided to update both of them with version UBUCNA2. When i tried to re root them back, even though the process have run fine a couple times the phone is not rooting. At this point i dont know what else to do to try to root those phones. I have tried every single method around this forum i think not just KINGO this time. And have not been able to reach root the way it should. Titanium backup shows not able to aquire root priviledges, and other root apps also. Can someone please help me on this?? Keep in mind im not a newbie so dont give me the recovery method advice without something new or to use KINGO because ive have done that already. Thanks a lot guys
You upgraded your phones to the latest knox enabled firmware which has the knox bootloader. You cannot go back to an older firmware or flash a custom rom now.
To root, try the directions provided in this thread and use the melius3gxx files instead of meliusltexx.

Ok thanks, the phones already had the knox apk so my guess was that it was going to be the same thing. Thanks for clarifying that one. And thanks for the advice.
Thanks again, turns out the only thing that is failling root access is when i try to unlock the phone via box. For some reason when its checking for SU access it fails. But thanks anyway i managed to solve the Root problem.
root.
I rooted through Phill touch Recovery.

[Q] Z2 Root and OTA

It may have been put clearly somewhere else but I can't seem to locate it. Apologies if I am asking an answered question.
If I root this phone (don't intend to unlock bootloader), however:
Will OTA stop working? (because of modification)
Will doing an OTA update on rooted phone remove root?
If so, is it possible to preserve root while doing an OTA?
Will removing all traces of root be as easy as SU uninstall?
With some phones, the OTA will be broken after rooting and some it will not. This is my first Sony and I wanted to confirm if this was also the case.

Will OTA stop working? (because of modification) No, it would not stop working if you just root
Will doing an OTA update on rooted phone remove root? It may or may not. Nobody has tried it yet. But normally we dont recommend doing OTA after rooting
If so, is it possible to preserve root while doing an OTA? No way till now.
Will removing all traces of root be as easy as SU uninstall? Yes, there is an option in SU to unroot the phone.

Hello,
Thanks so much for your clear and concise responses. Previously I've never been concerned about the unrooting of a phone or access to OTA. I just got so comfortable working with Samsung that I feel a bit out of my depth at the moment with the Z2.

So, we can just click unroot in supersu, not have to flash FTF using FlashTool ? After this method of unroot can we safely do ota ?

Rooting

I'm trying to get use out of this aging tablet. I figured there aren't going to be any updates coming so I would finally like to root the device. However, everything I've read and tried is outdated and hasn't worked. I was wondering if someone could help me root my device. I'm not looking to run any ROM or anything. I'd just like to have root and superuser access so I can uninstall a lot of unwanted apps. Below is my device information. I've just recently done a factory reset and have not installed any drivers on my computer. Starting fresh.
Computer:
- Windows 7 64-bit
Tablet:
- Android Version: 4.1.1
- Build number: 10.4.2.18
Any help would be greatly appreciated.

I tried using Kingo. While the program said it rooted the device, I didn't have root access when I checked the app Root Checker and Titanium Back-up to uninstall all the unwanted apps.

Is your device unlocked? If you're not and you don't have any warranty, try unlocking it first then use kingo. It's what I used on several TF201 with no problem, but they were all unlocked so I don't know if being locked would cause the problem.

My device is NOT unlocked. How do I go about unlocking it? After I do so, I'll give Kingo another try.
You can disregard! I tried Kingo again, without unlocking, and for some reason it worked this time! I am currently uninstalling all the bloatware. Thank you all for your help.

[Q] Getting my Galaxy S5 back to factory settings

Hey all,
I hope I am posting in the right section. If I am not please feel free to re-direct me. I have searched for the answer to my question and am not quite seeing the answer.
I have a samsung galaxy S5. I tried rooting it using towelroot. As far as I knew it was rooted. My understanding is that if you are rooted that you cannot get the OTA updates. My phone has an error when trying to install those updates. I tried installing SuperSU. It said I did not have the SU binary. I installed a root checker that stated I did not have an active root. My goal is to get my phone back to factory settings in order to turn it in for a new phone. What do I need to do that? Am I really not rooted anymore? Why won't the updates install then? If I back up my phone and do a factory reset will I run into any problems?
I understand that I am an absolute novice at this so any help is totally appreciated!
Try to flash the stock rom.
Try to flash the stock rom of your s5,then you can back to your stock and can update your mobile.
