Help an Andriod beginner. - Sprint Samsung Galaxy S7 Questions & Answers

Hey guys,
I need help.
The story:
My girlfriend has a Galaxy S7 from Sprint, she loves her phone but hates the carrier's splash screen (I think that's what it's called). The animation at the startup of the phone.
She truly hates it.
I want to do something nice for her and remove that from her phone. I think it's possible, I know I can do it, I just need help with the steps.
Laugh and call me names if you want, I'm a iOS user, it works for me, I've always preferred it. My knowledge about Android is limited.
I'm not a complete rook, I've rooted an Android tablet before, I've reloaded a ROM after deleting a few things and bricking said tablet but that's as far as my handheld device tinkering experience goes.
PCs are my cup of tea, I know my way around them, I'm not a developer or anything, I just like messing around and fixing them.
Anyway, all I want are the right directions so I don't ruin her phone.
Do I have to root the device?
If so, what do I use to root said device?
Do I need to install a new ROM to get rid of the splash screen?
Where do I download a stock version (I'm assuming that's what I'd have to install) of her firmware?
If I need to root the device, after installing the stock OS, if I un-root it, will changes be lost?
I apologize if I'm not using the correct terminology, I'm just trying to get my point across as clear as possible.
If this was a PC, what I would do is a clean installation using a stock ISO, making my problem and all the OEM's bloatware disappear.
I'm looking for the equivalent of that, but for her phone.
If there is a better way, or what I'm asking is for some reason not possible please let me know.
Her phone:
Samsung Galaxy S7 930P
Nougat 7.0
P.S.: The reason I want to un-root it afterwards, is that from what I understand you can't use NFC payments if your device is rooted and she really likes doing that.

You can remove it/ change it in two ways.
1. Root it, and change the boot animation, and then unroot. I would not recommend this, as rooting this device is hard if you're unfamiliar with Android devices, plus you need to flash an engineering boot.img, which completely cripples this devices battery and performance.
2. Use the universal firmware for the Sprint device. It will change the boot animation to a screen which just says "Samsung" in white font against a black background till it boots. It looks clean and is un-intrusive, and will get rid of all the Sprint bloatware. I highly recommend using that over trying to root and change the boot animation on her device. It is quite simple to do as well, as all you need to do is download the firmware, (find it here: http://updato.com/firmware-archive-select-model?record=48A2011F925C11E7963AFA163EE8F90B ) and unzip it, and flash it using ODIN (find it here: https://drive.google.com/open?id=0ByoIewGd_qk2MEZMb0l3Qlo4ek0 ) . Good luck!

[Q] Take 7.014.1 update before rooting ?

I've got a new A500 and I intend to root it soon, but I would like advice on whether to take the current update 7.014.1 being pushed before I go through the rooting process? It currently shows having 3.2 OS version.

Doesn't matter, the only way to root it is by flashing it which wipes it totally clean

My concern, being still in the middle of researching just how to root the A500, was whether the update would have a similar effect as, for example, the more major update from 3.0 to 3.2, which, as I understand it totally changes the procedure used to achieve root. But if it won't matter one way or the other, I might as well take the update in the interim. I keep hoping to see a more simple 'one-click' style of root made available before I tackle this task. So far I've found something like 3 different ways to root the tablet between this forum and another. But each is a rather involved process.
Thanks!

I downgraded, rooted, and then flashed the stock ROM without wiping. If going to any other rom, you might need to wipe.
There currently is no way to root a stock 3.2 or later tablet with a simple one click. In the past GingerBreak gave us that ability but since has been plugged. The other thing causing issues is ACER locked the boot loader making it difficult to flash in a new boot image to get to root.
=== 411 on rooting ===
So, if you have a tablet and want to root it then you have to start looking at security holes. This is what the GingerBreak exploit did along with others. But, ACER plugged those holes and as of today, nobody has found anymore.
So, you might look at exploiting an update.zip. These are OTA's that run but they are signed by ACER. So you can take it apart (unzip) and modify it, but you cannot resign it with an ACER Key. Therefore, you have to sign it with your key. Since it is NOT signed by ACER, the ACER recovery will not install it. So, you have to replace the ACER recovery with CWM which will install any update.zip regardless of who signed it. You just need to change the built in recovery by flashing in CWM recovery.
Lastly, you can just change the boot image and add root. This is easy and straight forward to do. This is just like making your own custom update.zip. Once you have your custom boot, you can then just use Nvflash to flash in your custom boot.
Now, fast forward. ACER (can someone please explain to me why?) decided to lock the bootloader thereby not allowing you to replace the recovery, boot, or any other area. Meaning, you cannot use Nvflash anymore without a key.
With the bootloader locked, you can only load new images if you know the key used to lock it. Of course, they use a public and private key combination, and they appear to use the serial number of the USB device as part of the public key making the keys on my tablet unique compared to yours.
With all this said, this ends all the easy simple rooting methods because first, they've plugged all the security holes (which they should do). Secondly, they locked the boot loader making it very difficult for people to just flash in a rooted boot image.
Armed with this, how do you root a 3.2? One way to do it is to get to a version prior to 3.2 loaded that has a security hole or does not have the bootloader locked. You now exploit it and get root. Now, with root access you make a 'backdoor' that only you know about which allows you to get into your tablet as root. With this done, now roll your tablet forward apply all updates. Since you have a 'backdoor' you can always gain root access.
Unfortunately, this gets to be messy or can be more difficult to do than just clicking on a GingerBreak application. However, if you follow the steps posted here in the forum, it's straight forward and easy enough to do. If not, you are going to have to wait for someone to find a hole and build a oneclick application. I wouldn't hold my breath on this, it probably will never happen because everyone is working on ICS.
Lastly, everyone should write to ACER, refuse to buy ACER (or any tablet) that doesn't allow you (AS THE OWNER) to change it. How would you like to buy a Ford to just have Ford lock the lug nuts on the rims so you could NOT put on your custom wheels.
I believe failure to allow owners to unlock these devices will be the downfall to Android. Windows 8 does NOT have such restrictions and businesses are not going to use devices that are locked and cannot be customized for business. Because developers write software they can sell, they'll move to Windows 8 and drop supporting Android and all these goofy flavors and restrictions. Android might be great and everyone hates Microsoft, but software vendors are going to NOT want to support all these devices.

Hi, and thank you VERY much for posting such a nice explanation, especially in addition to all the work you have done posting your thread rooting 3.2. I understand, and completely agree with your explanation, as well as your position on taking control of what we bought and paid for. I take even stronger offense with this tablet's bootloader being locked than I do on my phones. This is not a discounted phone with a service plan tied to a cell provider. It has WiFi, but " I " am the only one providing its data (it never leaves my home). There is no justification here that I am 'leasing' a provider's technology . It was a gift, so I can't speak to choosing the vendor. But I like your wheel lug analogy.
I've been reading the threads on rooting, and both my Android phones are rooted and ROMed, so I've been around the block a couple times from the rooting aspect. But thus far I have been rather confused as to which route to take with the tablet. I don't want to be limited to using terminal for su access, so I want to 'fully root' the tablet. My goal is to allow apps like Titanium Backup, Root Explorer, and others I use on the phones, as well as having Clockworkmod Recovery, or similar recovery capable of working with nandroid backups. But for now I don't have plans to use a custom ROM. So having rooted stock 3.2 would suffice.
Although I do fully understand the need to research these kinds of things before jumping in, I also know that often times information evolves, and lengthy threads which were once considered current info end up not getting updated during that evolution. This can lead to wasted time reading information which can no longer actually be used . So in the spirit of pursuing the most current info, could you recommend which thread I can use to get the best results while rooting this 3.2.1 OS Tablet with the above goals in mind?
Used Timmydean's method, it is pretty easy as long as you follow his instructions with in the zip file he has made with all the tools you need inside of hat zip file. You root, install super user and busybox then download Acer recover installer and that will install cwm...

Good luck and thanks again timmydean for this method.

Thanks, that sounds like the way to go. I'll head over to the link you provided.
I've got a couple of questions about the zip file at that post. I want to download that to my PC, and will be using ADB from there, right? I have the choice of doing so from either Windows XP SP3, or Windows 7 Home Premium. I read in older threads that many of the problems people had were only when they used XP, but were avoided by using Windows 7 (which was exactly opposite of what people experienced rooting the LG Ally), so it seems that in this case it is desirable to use Win7?
I presume I'll need to install a driver so the PC can 'see' the tablet. Is one provided in the tools, or do I need to download that somewhere?
I used windows 7. Yes the driver is in the zip file. I unzipped the file to a folder on my desktop and went from there.
In the zip there is a folder called usbpcdriver. Run the set up from within the fooder to get your driver... please read the instructions that say read me..
Sent from my A500 using xda premium
Thanks. I intend to read everything I can get my hands on before I actually start this. I definitely don't want any trouble or, heaven forbid, to brick the tablet.
pretty easy i think... good luck and let us know when you get rooted
I'm not finding any actual instructions on the steps to take for this procedure. The readme file in version 3 zip file only talks about "changes" from whatever the original procedure was.
Where can I get the actual instructions for the entire procedure?
Edit: I just downloaded version 2 of the zip file. In that one there is an additional PDF called "Steps". It is a little more detailed, and says at step 20 that "you should now have 3.2 with a SU shell installed". Does the DotNetDetector step actually ROOT the device? That seems simple enough, but it still has no mention of things like installing ADB and the PC driver. I located the actual thread from which the single post was derived (the target of the URL above, where it is suggested I use TimmyDean's procedure). I am now looking through that entire thread to try to sort out where the instructions are.
AHA! Post 119 of that main thread says "Also the instructions and everything you need are in earlier posts.".
It appears this procedure needs an instruction manual written to consolidate all the gathered information. Having a link to only the download zip files isn't telling me the whole picture. I'll try gleaning the thread and see if I can put together all the steps needed from start to finish to make this work. Looks like ROOT ain't happening tonight.

Good luck on jailbreaking the DemonSpawn 4.

he has updated it again. looks like a few steps where taken out to make it more simpler
good luck man. Iphone is jail broken
OK, so it looks like the file you just sent me a link to is the same one as the "Steps.PDF" file that was released in Version 2. It appears to me that what I need to do is blend the changes (detailed in version 3's readme file) into that original Steps file, to make a single contiguous set of instructions, and then start at the top. I notice it does mention installing the PC driver and ADB.
Do I have this right so far?

That was fast! Wanna do my tablet?
The link you sent just now is to the version 3 zip file posted on 12/25, which is what I had initially downloaded. It does appear he streamlined the procedure, but it is that readme file which leaves out the part about installing the PC driver and ADB in the beginning, and also leaves out the part at the end telling you that you should now have 3.2 with a SU shell installed.
Please understand that I want to be "fully" rooted, not just have the ability to gain an SU prompt in terminal. Will this procedure "fully root" the tablet? I'm confused by what he means saying "SU shell installed".
Yes if you use his v3 file you will be.. you will need to down load acer recovery from the market after you are rooted and then flash clockworkmod.. this should all take you about 30 min if that...

OK, thanks!! Rooting went well without incident. I just installed Root Explorer and Titanium Backup, and made a backup to SD of my apps and data. Then installed Acer Recovery Installer, and let it install CWM Recovery. But what is considered the "home" button on the tablet?? Is it the reset button? The only buttons on this thing are the Volume rocker and the Power button. ( I got brave and found out it is the POWER button ).
Edit: To clarify, I meant to ask which button serves as the Home button while you are IN the CWM Recovery environment, not while in the Android OS home screen.

[Q] ROM/Module & Other Question about my GS4

Hi guys, have a few questions...
For starters, I have a Samsung Galaxy S4 / AT&T
Running Android 4.4.2 Rooted with Towel Root
Connected on Straight Talk
~NC1
SafeStrap 3.72 (TWRP v2.7.0.0) Installed.
Im new to all this ROM/Modules and Rooting stuff.
Last time i fully customized stuff was on my Motorola RZR ages ago
making my keypad/ LED light blink with calls, and replacing the Cingular Logo
with a Pirate/2 Swords Logo. hah... good times.
I mean there was jail-breaking and whatnot but...that's easy stuff.
Any who, Im a quick learner so on to the subject.
My original idea was to FULLY customize this phone and install ROMS/other OS, thats
what im all about, customization. Sadly, i realized im on a NC1 which its Boot loader is
locked if im understanding correctly preventing me from installing other? ROMS?
However if i understood correctly, we still can install certain ROMS? Whats the difference?
Is there any ROM i can install that is clean? no bloatware? but with everything I need?
Whats the best, fastest and best looking ROM i can get? or they dont look different because the
boot loader thing? Or they can only be Samsung/AT&T roms? This stuff can be confusing. lol
Module wise, why do i need them? why arent they included in the actual ROM?
Also, is there any App/or way for me to know what causes my phone to randomly crash/reboot?
A few months ago I was at the GYM and my phone randomly shut off. It didnt want to turn back on.
After a while it turned back on, then it would randomly reboot. That eventually went away.
Last night, i was with some friends in a bar and my phone just turned off again. Didnt wanna turn
on...then the same reboot thing happened again.
Today, is working fine. I thought maybe it was an overheat issue but, i wasnt doing anything on my
phone and on top of that im using a CPU tempt program installed through xPosed and according to the
readings it wasnt hot, as it was in the 50-55c (or is that too hot?) Im at home now and its reading
36c but i dont have its case on (if that makes any difference)
There are 3 kind of "ROM"s :
1- Official ones. made by samsung. flashable via odin exclusively. not rooted
2- A bit modified (maybe more than a bit) Official ones, modified by people, flashable via odin or recovery (1), usually already rooted
3- Completely rewritten ROMS, almost made from scratch (Cyanogenmod, MIUI for exemple...), installable via recovery. already rooted
Now, your phone can be in two states : Rooted or not rooted.
From factory, your phone is not rooted (you can compare it to jailbreak)
with root, you become a "super user", which means you have rights on almost every single aspect of your phone, and you give authorisations to apps so they can act on system files (for exemple, they can get hidden informations, they can automatically install apps etc... infinite possibilites there are.)
As for the best rom there is, is like asking what is the best music ever, it depends on the user, you have to try by yourself to find the one that satisfies you the most.
For random reboots, i personally think that it is comparable to windows Blue Screen of Deaths. you maybe messed up something while installing something. your phone can't handle the bug, so it restart or shut down itself. so the safest way to get rid of this problem is to factory reset your phone (via the recovery)
if you are looking for stableness, don't opt for completely remade ROMS, they are usually experimental. but personally i use MIUI and i didn't have any problem and i love this ROM.
Hope i answered every question.
Thanks a lot for the reply.
I understand a bit better now...
That MIUI looks interesting... Reminded me of DreamPassport for my Sega Dreamcast, hah...
I'm guessing I cant install that one huh? Lol
well since you already have a custom recovery you can... just download a miui rom (one for your phone version (be carefull about the model) ) then put it on the root of your sd card, go to the custom recovery and flash zip from sdcard and choose it... but i advice you to factory reset your phone first in order to fix your reboot problem.
also, make sure you have installed the right android version before installing the equivalent miui version (for exemple if you want to install miui that requires 4.2, install an official 4.2 rom first) via odin.
Gotcha. Thanks.
One last question....
If I want my phone with the original OS it came with. But with all the bloatware removed...
which rom would be the best? , since I want the stock experience but no bloatware.
Also...
I noticed when you click to see how much ram is being used, it says
800/1.77GB
Isnt my phone suppose to have 2GB? Can I do something to get that back? is it cause the bloatware?
I appreciate the help.

I don't think the above information is correct.
From what I know the AT&T has a locked bootloader. So you can run custom roms, just not all of them. I think only custom roms that match the version you are using.
You could better read in the section for the AT&T (this section is for a different model).

Want to flash raw stock on Galaxy S4 GT-I9500

Hi there,
I am fairly new in android and ask for some guidance.
After over 1.5 years of getting irritated by bloatware on my galaxy S4 GT-I9500 I started to look for how to root phone and got rid off plenty of bloatware.
Huge relief. I mean, why the hell do I need tripadvisor, help, health, googlesettings, speech and tens of other completely useless apps (for me). If I need something I want to install it by myself and don't want it to be forced onto phone which I paid from my pocket.
Now, when I last time hard reset my phone, it "kindly" upgraded all the nonsense bloatware too. Grrrrr
I looked on the forums to flash raw android stock, but there is so much info out there, that I get lost.
Could you suggest, where/how should I start. So, I want completely raw android OS, without any bloatware (if possible), on my galaxy S4 GT-I9500.
Thanks

Hi mate
There are some custom roms very close to stock where you can choose what bloatware to install for example Omega rom ...not sure if is that what you meant....
Ok, this is probably what I am looking for, thanks.
I am downloading omega room for S4. I have a follow up Q though. When I read this http://forum.xda-developers.com/showpost.php?p=40243586&postcount=4 guidance to flash this ROM, it just says:
Installation Instructions:
1. Backup your device (nadroid backup, titanium backup, efs backup ... etc)
2. Copy rom to your device
3. Boot to recovery and flash Omega
Click to expand...

What is boot to recovery, what program should I use for this? Need some details how to do this. :
I am trying to boot Omega and everything goes completely wrong
when I get this --Install /sdcard ...
I get following
footer is wrong
signature verification is wrong
Any suggestion
You dont know how to boot in recovery...and trying to boot in Omega???? How you did that ? Are you rooted,custom recovery, flasht Omega ???
I think you better read,read and read about it,unlless you want to hard brick your device.

[Q] Accidentally killed stock recovery

Hello everyone! I'm brand new to the forums so if I am breaking any rule or regulation, just give me a heads up. So, some basic information about my predicament.
- own a Samsung Galaxy Note 3 from Verizon.
- I use t-mobile network. Works great with no problems.
- phone was successfully rooted via towel root.
I was looking to get cynagenmod on the phone so I started looking up guides and such. Only thing I wasn't aware of was that carrier branded versions can't have their recovery flashed. That said, I used flashify and the clockwork apk. The app did its job, killed the stock recovery, but couldn't load the new one. Now the phone says error, no recovery when trying to access it during boot.
It should be said that the phone still boots and works normally but I really want to get the recovery working so I can at least try again the right way to get cynagenmod working.
My question is, is it possible to get my hands on the stock recovery for my phone and just flash it back to how it was? Basically, how do I fix this problem I put myself in. Of course, I didn't make backups. During the whole process, I figured "if I follow this tutorial word for word, why bother with backups?" look how wrong I was
Any help would be sincerely appreciated. I'm posting this from my replacement phone, not my note 3.

Hi all. I'm new to rooting can any one please help and point me to the right tutorial to root a samsung s7

Hi All
Looking for a best tutorial to follow and the right one for my phone really don't want to brick it, obviously :/. as there seems to be a few versions for the S7
I have the following: S7 android 8.0.0 SM-G930F not sure what else I need to know! I'm in the UK so I assume UK phones come with Exynos cpu's
and as far as I am aware android 8 is Oreo! but when they say Stock Rom I assume they mean the same as what came with the phone the original rom?
if so is there an alternative stable rom without the crap included or is it just as simple to delete every thing you don't want now it's rooted! and does that mean if I reset the phone its back to normal with all the crap included! or is there a way to keep it rooted even after reset! and should anything be disabled I.e prepare the phone before attempting to root like any kind of auto encryption that needs disabling and just one more question
if at anytime the rooting process hangs for a ridiculous amount of time when should I throw in the towel! and what are the chances of retrieving the phone back to original state! or does a dirty shutdown brick it?.
I started the root process but failed at first hurdle!, followed instructions install Odin3_v3.13.1 but when I connected the phone nothing showed up in Odin? though I will have another go just to confirm I followed it correctly, I'll update this when it's done.
this was the tutorial I followed:
Easy 4 Newbie [Root Guide]SM-G930F, G935F, G930FD, G935FD (Samsung Galaxy S7 Edge)
Warning ! Please note that the official TWRP for Nougat on Galaxy S7/ S7 Edge is not available yet but based on my experience the Marshmallow version is working on Nougat. By installing a custom recovery on your S7 and S7 Edge and rooting it...

I know alot of questions I would really appreciate any help and clarification on the above.
many thanks

Look pal, rooting the phone is just like being an adult, it means you will get rid of Samsung's "Child Care".
Yes, UK models use Exynos chip, but you have to be sure, look at your baseband version, if it is G930FXXX, then you are good.
ROMs are in two shapes:
Stock-based: These are just like the one you are using, or other Samsung phones does, like Samsung Experience, One UI, TouchWiz. Maybe MIUI and FlymeOS will come into account, as there are ROMs based on them + Samsung's.
AOSP: These are pure Android ROMs, with few modifications to the core, but keeping the UI as close to the source as possible, Google & OnePlus phones come with a near-to-pure operating systems.
Changing a ROM is not risky, as long as you follow the instructions, without any unaccounted improvising.
Before you install a ROM, read the working and bug list, to make sure you are installing something you have an idea of.
You need to install TWRP recovery (or any other one you like), and format data, in order to be able to travel among ROMs and/or root your device.
Formatting is only required because the phone is forcibly encrypted, and TWRP can not decrypt it, at least not for this device.
Rooting is simply about flashing a 5-MB file, Magisk, then rebooting to system, no need to wipe data.
No need to do any additional steps, unless you are trying to hide root from some apps and/or pass SafetyNet.

Hi Mohamedkam000
Thanks for replying. I'm not confused about why I want to root the phone. I'm just trying to understand the inner workings and the risks as I'm not as clued up with phone OS's as I am windows. I don't care about warrantees or hiding the the fact it's rooted I just want a clean rooted phone free of big brother well inside at least I know you will never completely keep them out but making it hard is a start lol.
Thank you very much for all the above especially on clarifying about the roms and the reason TWRP formats due to encryption nice one
My Baseband version slightly different though it's G930FXXU8ETI3 not sure if having a U instead of a third X makes any difference!
and I posted wrong tutorial I'm actually following this one below again not sure if that matters.

It doesn't matter which version of Android you are using, root is the same.
However, on stock ROMs, it might sometimes get rough, as you may end up with Wi-Fi not working (happened to me Q1 2020).
If you really want to learn how Android OS works, then rooting the stock ROM is not your way.
Try AOSP ROMs, preferably start with Oreo ones, you can root in 3 common way, LineageOS SU Add-on, Magisk, Super SU.
But before you tickle your phone, you have to make a backup of your current device, of every partition, EFS is the most important partition, so make sure it is safe.
Baseband version doesn't matter a lot, unless you're paranoid with updates, it is sorted alphabetically, each string on its own.
The phone is more similar to a linux machine than to a Windows PC.
Edit: To root stock ROM, you have to flash dm verity, so you don't end up encrypted again.

Thanks again for clearing quite a few things up I thought rooting stock rom would have been far safer way forward wow how wrong was I! but I guess I am just trying to find any kind simile to windows in any way but as you pointed out again it's more like Linux which again I've only played around with ubuntu and mint for a short period so again not to up on Linux lol.
It's funny I was just reading up on AOSP ROMs then got your message. I see they have a stable but not complete! Android 10 not that I would consider it need as I need a stable OS so Oreo is fine for me.
I have backed up phone using Smart Switch on the PC I assume that copy's every thing that's needed, I reset the phone in anticipation all be it prematurely but at least it restored all my data so if anything that was a good test of the back up at least .
I will have look at some AOSP ROMs and see what's involved there, I'll check out their tutorial hopefully it will include the whole process including root.
I gather by your comment using a AOSP ROM you don't need to use dm-verity or will that still be needed!.
The first thing to do is to flash (install) TWRP, it's a custom recovery (think of it as a mini OS that can boot before Android), that will be the base for any of your future tinkering.
Here is the thread, read the FP carefully: [Recovery][Exynos] Official TWRP for Galaxy S7 (herolte)
Once TWRP installed, you can do many things:
Install addons like Magisk. Magisk is the tool you use to obtain root. Forget SuperSU, its outdated, and don't works in modern versions of Android.
Install a custom ROM (this subforum is the perfect place to find them).
Backup & restore an image of your current ROM (very useful).

AOSP ROMs are pure, you can't say they are not complete. They are complete, and what OEMs do, like Samsung and Xiaomi is just a customization that you can do, too.
It is preferred that when you take a backup, take it with TWRP, just to ensure you backed up phone's partitions, along with "EFS".
The root procedure on Android 6+ is done by patching the Kernel (boot.img), so unless you take backup of that, you cannot keep root.
There are stable custom ROMs, custom ROMs are meant for custom adjustments, however the stability depends on your phone, and the way you use it, you can compare AOSP vs. Stock and see the difference.
AOSP ROMs doesn't need dm verity, well, at least not if the developer did not mention the encryption part.

Some of the roms I have looked at mention external touch buttons at bottom of phone do not work or something else in the phone I'm just reading their comments.
I understand about the stock & custom rom's now that's not my problem at least not at the moment as I am miles away from choosing a rom! as I can't even get out the starting gate!. I can not get TWRP on my phone as the only way I can see to get it on a unrooted! phone is to use Odin but as I said Odin doesn't work at least not for me it does not see my phone. I would love to take a back up using twrp but that won't happen until I find a way to get TWRP on a unrooted phone. what crazy paradox is this!. you can't root phone without twrp installed and twrp won't install on a unrooted phone!. that makes perfect sense.

Does your phone allow MTP communication? I mean can you transfer files when the phone is turned on?
Does the phone show any notification about a usb connection?
If not, then you have probably a bad USB cable, at least, or you have a hardware issue that can go as deep as a burned charging port.
If yes, then either your USB cable is not as fast as the phone requires, or you haven't installed the Samsung USB Drivers on your PC.
Unfortunately, you cannot root your device without PC, at least not since Lollipop.

Hi
Yes I can transfer files.
Yes phone asks to allow or block file transfer and it ohone shows up in Devices and Drives list and I can access the phone directory and shows up as Samsung s7 icon.
I will try another USB lead but the one I'm using is new and wasn't cheap but still a possibility I have had leads that weren't suitable for other things I was trying so it is worth a try.
Thanks

When I downloaded Odin this was latest one Odin3_v3.13.1 though I have doubts that one version update will fix this issue as I did not see many if any people having my issue so they all used Odin and I believe theirs are fine even with older versions! but as I said Mohamedkam it's worth a try I will down load that version and give it a try.
As for the Samsung usb driver I believe that is where I got mine
SAMSUNG_USB_Driver_for_Mobile_Phones no version visible under properties on file version 1.7.23.0.
The USB connection seems to be fine I have uninstalled then re-download and reinstalled a couple of times.
I can transfer files no problem it shows up as Galaxy S7 Icon with card and phone drive inside.
I'll update shortly thank you.
Update:
I just went to try new Odin and whilst checking my phone have seen I have Offical TWRP app installed? I have no clue as to how that's got in there! as Odin did not show phone so I could select nothing!.
In the phone I open app and if i select backup existing recovery it opens and Select Folder tab and under that Selected Folder: /sdcard Filename: Recovery .img and at the bottom of screen Root access required.
I just hope it's installed correctly!. it is showing in playstore my apps as well just to confirm. if this is now installed what should I do next Now not sure what tutorial to start following.
I am just going to try the new odin and see if it picks up the phone back soon.
OK Seem that it now shows up in the new Odin. at least I think it has! in the log window I see this: <ID:0/004> Added!!
I didn't see that before.
Would be grateful if you could tell me how to proceed from here!
Correct, you don't need he latst version of Odin or the Samsung drivers, bit it was just to be sure.
You need to be in download mode, but before, you must have checked OEM unlock & USB debug in developer options (mandatory).
I've written a tutorial with images here (in French):

As I said the older version did not show any kind of data what's so ever and the phone was in download mode. phone displayed "Downloading" which I believe it says that even if it's not doing anything! so a tutorial explained. I think it must have installed the Official TWRP app even though phone did not show up in Odin everything was blank however when I installed the new version of Odin like you suggested it then showed up as <ID:0/004> Added!!. so your suggestion work thanks for that and I did enable OEM unlock & USB debug I did long time ago.
I would check out your tutorial but unfortunately I don't speak French and translating instructions is too risky but thank you for the offer but I'll carry on look around still undecided on what custom rom to go for as I said some comments point out small issues and the developers also state certain things are not working so that is making it hard to consider one if you know what I mean.
Again Thank you for your input very much appreciated.

Take a note that, when you flash TWRP, you have to boot immediately to the recovery, so as to enforce its existence, cause I remember they phone has an original recovery backed up somewhere, and gets triggered when you reboot directly to system instead of the unofficial binary.
I advise you to watch guides on YouTube, it's more .. understandable.

Yer I read that but I've ended up with TWRP installed and did not do that process because I was unaware it installed until it showed up.
As I said I'll just keep looking for now I know I'll find one that works for me from start to finish.
and I've been checking youtube but wouldn't want to use any links their providing but it may help familurise myself with the whole process if i watch enough of them.
Thanks again for your help.

Hi Mooms
I will check that out many thanks. I wonder if you could help me here. I am in the middle of the rooting process but have hit a snag. again!
I have now installed TWRP successfully then no-verity-opt-encrypt-3.1 all went fine and I'm at point of flashing Magisk but have an issue when I swipe to flash is gives me a error in red saying "invalid zip file format !"
I downloaded it from github here.
GitHub - topjohnwu/Magisk: The Magic Mask for Android
The Magic Mask for Android. Contribute to topjohnwu/Magisk development by creating an account on GitHub.
github.com
I click on "code" tab and then "download zip" and I placed that in a download folder on my sd card when I select it I get the above error any ideas as to why I am getting this am I downloaded the correct file?
thanks for any assistance you could give.
