how to permanent disable all data connections from galaxy s4 phone - Galaxy S 4 Mini Q&A, Help & Troubleshooting

I’m new to this forum, and I’m new to android, with the minimum knowledge in developing or modifying anything in an android phone. So, I’m asking if someone has solution on my issue, should he please explain it with all the details.
I just bought 3 phones, SAMSUNG GALAXY S4 MINI VERIZON SCH-I435 - ANDROID VERSION IS 4.4.2 [maybe just 1 that I selected on the phone to update the software, and the others (I still didn’t opened it also no line on it) are maybe 4.2]; I need it for 3 employees that I want to use it with a specific program for my business that it not needed to be updated continuously, and its suppose to getting updated daily with a direct USB connection to our server.
My issue is, that for many reasons I want that the internet and any type of data connection should be fully disabled, no browser, no e-mail, no data apps, no in apps purchases, no MMS messaging, and also no video. Just Talk & Text and. So I’m wondering if it’s possible on an android phone to disable all data apps and block all data connections, in a way that it shouldn’t be able to restore it back.
Before I came here, someone told me that I can do it if I first root the phone (he also didn’t know what I need to do after rooting) he gave me to try a few programs to root the phone, Super User, TowelRoot, Kingo ROOT ,Super SU but as I see nothing worked for my phone. The SuperSU gives a message that it cannot find the SU binary, and the others don’t work for other reasons – I tried to search somewhat on the internet about this kind of problems with rooting this model phone, and I found some complicated guidance with a combination of a few downloads, what I even didn’t understand the instructions how to do it, and I’m also definitely afraid of damaging the phone, and maybe after all it will still not work for me to root the phone – and the main thing is that my goal is not rooting the phone, but to totally disable any internet and data connections from this phones.
So I’m asking if someone can please give me a step by step solution for this kind of modification on this model phones, to permanent disable all data connection from the phone, and if 1 of the steps is to root the phone, then I also need detailed information from someone who has the experience with rooting this model phone with this android version.
I will appreciate everyone’s time and effort to help me.
Thanks
P.S. if my issue can only be solved by a paid android developer, maybe… I’m willing to pay some amount to do this. So if u see this for the only solution, then please direct me to a reliable developer. depends on price, experience, and more, to decide if willing to pay

Hello, i think to achive this someone have to create a modified rom(maybe based on samsung's stock or even cyanogenMod). I dont think its pretty difficult, but i dont have the wright knowledge to accomplish this.
But i can help you for rooting the phones. S4 mini s running 4.4.2(lets call it v1). But samsung pushed an update again on 4.4.2 after some months(call it v2).The v1 is easy to update with towelroot.
But the v2's kernel cant be rooted with that way. I follow some instructions from a post here on xda and i rooted mine. If you are on v2 you have to flash v1's kernel with odin, root it and then flash the v2's kernel.That's the way i did to my phone and i successfully root it.
You can download from sammobile all the stuff you need(kernels). I think it will gonna work for you too. To check if you are on the old(v1) or on the new(v2) rom, try towelroot and if it fails you are on v2, else on v1.

Thanks.
First, how do i get such kind modified rom?
second, about rooting. I tried already Towelroot and its not working, so maybe this means that i have already the update that you call V2. how could i know if i have V1 or V2?
also can you please explain me in detail your solution. Sory Im a novice in the android language. what "odin"?, how do i get it, how do i use it?, what means flash? how do i flash v1's kernel? and how do i flash V2's kernel?
Thanks again

About the 'modified rom' you have to wait for a response from someone with the knowledge to do this. There is no reason talking about root from now.
You can pm some developers and ask for help.

Maybe try something like LBE Security think you can deny access to things like that and maybe have a master app password. Maybe try looking under Android development forum under software or general. You may get a better response to your question, as it's pretty much just a device topic here. But I would think on Android such things should be possible.

[Q] I need an adroid education

Hey guys... plain and simple, I need help. I'm kind of a noob, but not really. I know a little bit here and there but I want to get good with my Evo, I mean really good! I'm currently browsing XDA in my car (Evolution X) tethered to my Evo 4G. Love Evo's. I'm also on a macbook pro, which makes a lot of the standard rooting options difficult for me, and i'm not running boot camp on my mac, so I don't have windows access.
Anyway, I want a foolproof, safe root. Currently I'm rooted with unrEVOked3. I hear not so great things, especially that full root might not have been attained. I want to confirm this and I don't know how. I don't want to be stuck with a root that might brick me in the future or give me problems down the road. I'm considering unrooting unrevoked and re-rooting with a more solid root method. I know that it doesn't matter the method as long as root is attained in the end but, from what i've read, a lot of people just don't agree with unrevoked method. I'm also concerned about the updates that unrevoked will provide when OTAs come out.
Here are my objectives...
1. Be familiar with the definitions and common terms root users use. For example, I want a clear understanding of recovery mode, HBOOT, bootloader, setcpu, kernels, etc. I know a little bit, but I don't feel comfortable enough to start messing around with flashing roms, changing kernels, etc. I want to be though.
2. I want to be able to flash roms.
3. I want full root and guaranteed SU permissions.
4. Wifi Tether.
5. ability and know how to overclock and underclock depending on the situation i'm in.
I know a lot of you guys will tell me to search and READ READ READ, but i've been doing this since I got me Evo about a month and a half ago. I rooted with unrEVOked3 because on my mac it was a simple download and click.
I downloaded the android-sdk-mac-86 download and I also have ECLIPSE for mac. I know these are app development programs, but will this help me with root and everything from there on?
Does anyone have a link to a site with definitions and explanations or is someone willing to take the time to explain to me these definitions and how they relate to android and effect the phone...
I appreciate you guys helping me. If you're going to tell me to use the search button or read the stickies, please save it, my laptop only has 3 hours of battery and i'm driving cross country and checking the forums while i'm riding shotgun.
Thanks in advance.
my 6th objective is to have all the apps i'll need to monitor and maintain my phone as best as i can.
I know about ROM manager, setcpu (don't have yet), Titanium Backup, and system info.
is there an app that allows me to browse ALL folders on the phone? currently I have ASTRO.

[Q] Time to ROOT my EVO!

I love the phone and its has been keeping me sane here at work.
However i hate the fact i cant use HULU, or Netflix. Not to mention the lag i have been getting with the phone.
I love this site and all the different themes and roms available.
All my friends are telling me to ROOT THIS PHONE! if i want to really experience the power of the phone.
I have read many of the rooting tutorials however i dont see any tutorial for hardware version 003.
Can anyone direct me to the correct thread?
The hardware version doesn't really mean anything when it comes to gaining root user access to your device.
The main factor in determining which root method to use is your hboot version. You can find the information on how to get this, and links to preferred root methods...
HERE!
AWSOME! THANK YOU! i have been reading all the posts here and reading up all the different methods.
That Hardware version was the only think stopping me
I would like to go to the Android 2.3 after i root it.
Can i skip going to Android 2.2 Fyroro? (is that how you spell it?)
Anyone have an answer for me ?
Also did anyone start getting bluetooth issues after the PRL update?
I dont think its related, but i got a new car and it will not connect to the bluetooth of my car.
Well it does but it will disconnect constantly, before it would connect fine and i would be able to stream form it.
I sure miss that, now i cant even use the bluetooth to make calls on it because it looses its connection and i have to re-establish the connection constantly.
Do bluetooth go bad on the evo?
Yes you can go to 2.3(Gingerbread) Android, but it is still in development for the Evo and is not stable and does not support HDMI and 4G at this time. It is in the works and 4G may be available in the next Cyanogen release which will be 2.3.1 Android version. If you want a Rom that everything works on you will have to flash a custom Sense based Rom which is a customized version of the stock Rom that came on your phone which are all 2.2(Froyo). Some are stripped of most HTC and Sprint apps and some are pretty close to stock with root. I would suggest reading the first post in all the Rom threads over in the Evo Development section to find out what is and what isn't working in each Rom. Read and learn about what all the terms mean like AOSP, Sense, Kernels and pretty much anything else you don't understand when reading about the Roms. It is best to get as much knowledge as possible before rooting and flashing because there are some serious risks. I don't mean to scare you because I highly encourage you to root, but I also encourage you to read and learn as much as possible before doing it. That way if you run into trouble and need help you can give a better description and it will be less likely that you will need help because everything you need to know is here on XDA.

[Q] Rooting and ROM

Hello, this is the first time posting on this forum and relatively new on the android platform after jumping ship from blackberry. So, i have afew questions i hope you guys can help me with.
1. I heard/read alot regarding rooting to bring out the full potential of an android(s4) phone. What is the full advantage of rooting my phone? How does granting administrative access affect my phone performance?
2. I often see the jargon of bloatware on this forum, what does it exactly mean?
3. What is the function of ROM?
Sorry if these qns are repeated, please direct me to the answer if it is already present in the forum. thanks

Rooting your phone gives you access to do anything you want ie (Apps 2 sd) that the phone dosent permit you to do.
A ROM is just a different feel, and its a faster alternative in upgrading your android ios. (S4 has touchwiz, can change it to Htc Sense)
Bloatware is a bunch of unnecessary apps that Carriers know youll never use but have it just cause. Its annoying and it takes up space. Rooting allows you to delete these apps, cause if its not you wont be able to remove it.
I hope this helped, ask again if you have any more questions.

I was wondering if there is a sort of rooting guide for dummies out there. I want to root my phone to get rid of some of the bloatware that I will never use, and also to delete the annoying start up and shut down sounds. Other than that, I'm happy with Touchwiz so far, but I suppose adding custom themes would be fun.
I rooted my last phone (Samsung Vibrant) over 2yrs ago and don't remember how I did it. I know I installed a custom ROM, but don't remember how to do that either. I remember following a really good guide with pictures and step by step instructions though. It's early days yet with the S4, but I really hope someone will do the same kind of guide because it's very helpful for those of us who like to customize but don't have the time or knowledge to seriously get into it. When I look at some of the threads on rooting it just seems like a foreign language to me!

Try the motochopper method - the guide is pretty simple and self explanatory however if you're on latest kernel then rooting is a no go as of now

Thanks I looked at that and it seems straightforward, but I'm concerned about what to do after the actual root. Things like how to back the phone up in case I mess it up, how to delete things, how to add things. Also I find a lot of the terminology confusing... not quite sure what all the acronyms stand for either, like ODIN or CWM, or what each thing does exactly. This is the kind of thread which would be totally useful: http://forum.xda-developers.com/showthread.php?t=849028 (this one is for the Vibrant though, so I think a lot of it would be different on a different device?)
As far as the kernel... as far as I know nothing has been updated. I got the phone on the first day it came out so I'm assuming it doesn't have the latest kernel. How would you find out? Not even sure what the kernel is or what it does :\ I would like to find out though!
^^^then you might be on an earlier kernel version anyway trying to root by motochopper method won't brick your device even if it doesn't go successful so no worries.
ODIN is the same software that service centres use to revive your bricked device - as a matter of fact with Samsung drivers, a usb cable and stock rom downloaded from online sources like sammobile, you can revert almost any instances of soft brick. Simply saying ODIN will flash back factory/stock rom anfd make your device as it was when you bought it. And yeah flashing via ODIN and all are more or less same procedure for all Samsung devices
Cwm is a custom recovery. If you don't know what recovery means it might be worth googling for better understanding the concept as even my knowledge is limited and my explanations might fall short of your expectations

with regards to rooting my s4 which is running on 4.2.2 jellybean, does motochopper actually brick my phone? In addition, can i root my phone to remove the bloatwares and afterwhich, unroot my phone again, with all the bloatwares already permanently removed? Is it possible to download the full list of softwares of the s4 online such that if i accidentally remove an important software, i will be able to restore it. As I am someone who is not into very much customization and over-clocking, i believe i dont need my phone rooted for custom ROM right? I can use stock ROM when my phone is unrooted and clear of bloatware?

Steps
#1. Locate GS4 box, place phone inside box.
#2. Return to store and get iPhone.
Serious tho. Best thing you can do is READ. SEARCH and READ. SEARCH and READ.
If you are unsure about something, READ again. Most questions have already been asked and answered.
If you find yourself lost......SEARCH and READ. Believe me this is this most useful advice you will ever get here.
Stuff is so easy now compared to when android 1st started. I remember rooting my G1 on a terminal prompt and installing recovery with wicked long commands. Now everything is automated and the hardest (NOT) part is reading the step by step instructions provided on almost every mod and tweak.
Welcome and goodluck !

[Q] [Sprint - SPH-L520] Need some pointers.

Hello everyone,
I recently signed up for a new Sprint contract and got a free Samsung Galaxy S4 Mini (Sprint model -- SPH-L520) however, everything I can find relates to rooting the GT-I9195 and GT-l9190. All I want to do is root it to be able to run apps that require root, I don't necessarily need a custom ROM loaded on it.
I do know some programming, though the languages I know probably wouldn't help much for this, and consider myself an advanced user of many desktop and server operating systems (Windows, Linux, some BSD). Although I am new to Android I'd like to give it a shot, if it's not too far out of my reach.
I'm really just looking for good starting guides and some tips from the pros. I've done a lot of Googling and researching on these forums but I haven't really found any guides that starts from scratch. I'm am willing to take the time to learn even if it takes a while.

I know this may seem redundant, but make sure you have the correct Samsung drivers installed (reinstall them and restart your pc). Make sure your PC recognizes your phone in debugging mode.

Unrooting S20 Plus

Hi all
Hope this is the correct area...
My hubby bought me a S20 plus for my birthday through a local dealer.
I noticed a few issues like not being able to use biometrics or install certain apps.
I've since found out the phone has been rooted.
I've tried to do a factory reset, but this hasn't helped.
I've downloaded root checker and it confirms the phone is rooted. I've downloaded SuperSU yet is won't work as ver 2.82 claims it's for an older Version of Android.
I've downloaded solid explorer to delete the root access files such as Busybox and SU however I cannot find these files in the system folder or the system/bin folder.
Can anyone advise on how I can unroot my phone? I am unable to install certain needed apps due to this.
Phone details below. Sorry am unable to upload pics.
UI Version = 1
Android Version = 10
Let me know if other info is needed.
I've even tried calling the Samsung Center and they are unable to assist...
Thanks all

You will need to get hold of the stock firmware from somewhere like Sammobile and flash back to stock using ODIN. There's tons of guides knocking about on here for the step by step. The damage is done though as far as any Knox related features go, it's like a fuse that blows when you root and you can never fix that.
Having said that, biometrics should have never been affected by rooting so that's a bit unusual. Flash stock and set up from scratch then go from there, could be faulty also
Thanks for the guidance Dave. I'll search the forums for the steps.
For clarity, when I say biometrics didn't work, it works allow me to record etc, but when I tried to enable it, like on my banking app, it wouldn't allow me. This is how I eventually figured out my phone was rooted. While I know the benefits of being rooted, a normal everyday user like myself, certainly won't benefit from it.
I've had a Samsung my entire life, and always saw the secured by knox logo... When you say damage has been done, does this mean that all my security in the device, such as my banking details etc, may be compromised?
Jees. I hope not. As this would really freak me out...
Ok so Finding the firmware wasn't to difficult. Sanmobile quite easy to navigate.
Just a query please... My phone base band version lists g985fxxu1atb2 however the closest I could find to this is G985FXXU1ATBM
Is this ok or does it have to be the exact same description?
Shoo. Lol. Really hope I'm going to be able to get this right **insert nervous smile emoticon here**

The last letters are the region/operator of the Rom. Not necessarily has to be the exact description, the really important are the first that indicate model number.
Ok. So have downloaded Odin and am busy downloading the flash firmware.
May I please be so bold as to ask someone on here to please share a link tot he step by step guide that I will need to follow in order to flash my phone back to the original boot thingie :silly::silly::silly:
I have tried to search but seem to only come up with a nexus thread with no mention of Odin.
~Sorry to ask, but little overwhelmed LOL and want to make sure I do this properly and not screw up my phone.
REAL noob here, so apologies if I come across lazy and getting others to do the work, but am really grateful for the help.
Maybe I'm searching incorrectly???
I found this somehow....
Is this it?
https://forum.xda-developers.com/galaxy-s20/how-to/howto-root-s20-series-upgrade-firmware-t4079353
**fingers crossed**
Can you unlock your phone with biometrics? Im guessing only the banking apps don't work because it's rooted. If i remember correctly most banking apps and maybe Google pay(not sure about that) stop working after rooting because the phone is "compromised" and it's not safe. You have to hide your root status from these apps and they will work properly then. Maybe someone else can help you with that because i do not remember how to do it.
Hi Marto
Yes, biometrics does work, although not really good. But that's probably due to the hectic screen protector.
Correctly so, it's mostly the banking / payment apps that won't work, and I can't check or download any software updates... Although I belive this can also be done manually....
But wow, there's an app that hides the root status? That might be a whole lot easier than re flashing. Truthfully I'm Sh!tting myself at the thought of attempting this ????

if the phone was bought as new, go back to the dealer and demand a new one that is not rooted.
could also be that your husband rooted the phone and installed software that keep tabs on what you do.
