So I am new to the whole Root and ROM Android arena. And I came up with a few questions that hopefully you guys can help me with.
1. I read people saying they lost their ROOT after an update from 4.1 to 4.2 or 4.2.1 to 4.2.2? How did this happen for them?
Do you have to Un-root and flash to stock before updating to a different build (Such as 4.1 to 4.2 or 4.2.1 to 4.2.2)?
2. Right now I am using a custom ROM on Android Version 4.2.2.... if a new Custom ROM with a new android version released (Let's say 4.2.3) can I flash from one Rom to the other with just wiping Cache/Factory wipe and Dalvik Cahce or is there something else I would need to do because of the Android version update?
Sorry those two questions above are very similar but I wanted to ask them both ways.
3. If I were to get bored of the Custom ROM I am currently on. Are there any Best Practices "rules" I should know about when switching from one custom ROM to another?
4. Last if I am on a custom ROM with a nightly build..... is it more common to update to every nightly build that releases? Or is it more common people to only pick and choose choice nightly build versions. And if people do update to every new Nightly build.... can you update too much and destroy your device?
Sorry guys I know these seem like very basic questions..... and Yes I did search the forums. However while I found some very basic answers nothing went into great depth in explanation. All the answers seemed to be very vague.
does anyone have some suggestions on where to find these answers?
1. If you are on stock, rooted, and you update versions of the OS, you are essentially UPDATING the /system partition. That is how you lose 'root' when upgrading. If you modify any system files while rooted, you have to either revert to stock or change those modified files back to the original before running the update.
2. Just run FACTORY RESET in your custom recovery and flash the new custom rom. No need to wipe any caches (/cache is wiped during a factory reset anyway). It doesnt matter what version to what version. Sometimes new versions might require new bootloaders, but you will be bombarded with that information here if that becomes the case.
3. See number 2. Its the same thing. backup your apps with Titanium Backup, do a Factory Reset in custom recovery and flash new rom....done.
4. doesnt matter. you can update as much or as little as you like. some people prefer stability over new shiny, but then others are just crack-flashers....and will literally flash ANYTHING posted to see what happens

Thanks I really appreciate the response. :good: You'd be surprised how many "Tiny Parts" of answers you get from searching. Very rarely the whole answer you need.
I am glade to hear that Question 2 only requires you to just factory rest. From the misinformation gathered on other forums... I was starting to think you had to flash back to stock before updating to another Custom ROM Build.
@20mmrain
You've probably looked at a number of posts by confused newbs. For better or worse, this site is nothing like a moderated wiki, so you find treasure mixed in with trash.
Rooters fall into four broad classes:
(a) Those that "root & modify" stock ROMs
(b) Those that abandon stock and use custom ROMs and kernels
For each of the above cases, there are diligent and careful users who make full (nandroid) backups... and lazy idiots who do not. It is almost always the lazy idiots you observe coming in here in a panic, independent of whether they are in class (a) or (b).
Beyond that, newbs taking approach (a) seem to perpetually labor under the false impression that their modified versions of a stock ROM should be able to be upgraded by the OTA process - when in fact that there is absolutely no reason to believe that. The OTAs carefully check hundreds of different files before they perform any changes; if even a single one of them has been altered, the OTA aborts without making any changes.
It is *possible* that if none of those hundreds of files are changed that an OTA will succeed on a "nearly stock" ROM. When this happens though, it is quite typical that:
- the "su" binary (part of a root kit) in either /system/bin or /system/xbin gets its' setuid permissions reset by a recursive permission-setting command in the OTA
- the custom recovery can possibly be overwritten by the new stock recovery.
Folks tend to refer to either of the above as "losing root". True in principle, but they are trivially fixed up - if the user actually understands how Android rooting works. (With fastboot, you simply reflash the custom recovery, boot into that and reflash the same root kit originally used).
It's too bad that folks who put together rooting guides seem to neglect putting an emphasis on making backups. They give you both security and freedom.
Bottom line: whatever you choose to do, make nandroid backups. You don't need to keep them all on the tablet - but for convenience reasons, you should have at least one known good ROM as a backup available to be restored.
good luck
Wow that is a really in-depth explanation and that is exactly what was looking for! Since I have been working in the IT world for years I will say with pride that I am an individual who believes in safety first and always back up any important project I am working on! So I am happy to hear I made the right decision there.
I guess a great deal of my questions also stem from working in a windows based world for so long ....that I am still learning Linux/android.
Right now I do keep a nandroid backup on my nexus 7 but only one. How backups do you have? And do you just keep the rest on a thumb drive?

At the moment I have 6 on the tablet - all generated in the last 60 days. Two in the last two days (one a rooted stock/jdq39, another a cm10.1 nightly). Plus recent TiBu market app & data backups. 32 GB model, so I have plenty of room.
That doesn't reflect any particular strategy or goal. I hook it up to a PC every once in a while and at that time either copy off any backups worth saving or delete them. Most of the those I have on the PC will eventually be deleted as well without ever being used. You could use a USB key if you want to. Really you only need to keep one on the tablet - mostly as a convenience in case you wedge your daily driver ROM with some random mod: you can restore a working ROM right from your tablet rather than having to find a USB key or return to your PC to get the tablet booting again.
There is one type of ROM backup that I think is very useful to keep a permanent copy of - a pure stock ROM. The reason for that is that any radio images (tilapia) or bootloader upgrades that are *sometimes* delivered by OTA can be trivially installed by:
- make a backup of the current ROM
- restore a pure stock ROM backup (including the stock recovery! ***)
- take the OTA
- ***soft-boot a custom recovery and make a backup of the NEW stock ROM (including its' recovery!)
- hard-flash the custom recovery to the tablet
- restore the backup from the first step above.
Doing things this way is the safest possible way to install either a bootloader or a radio image. Not only that, but for folks that prefer to mod stock ROMs, it gives them a backup archive of /system to recover arbitrary (stock) files from.
*** soft-booting a recovery is the most convenient way to capture a stock recovery as part of a nandroid backup. I.E.
Code:
fastboot boot recoveryimagefile.img
If you hard-flash a custom recovery before you make a nandroid backup of a stock ROM, you lose the opportunity to get a copy of the stock recovery along with the rest of the stock ROM.
good luck
EVGA Tegra Note 7
4.3 jelly Bean
Used the Super Tool to flash drivers and unlock bootloader.
Installed TWRP Recovery
Rooted using SU
Everything is working great, at this point.
Failed to back anything up
Flashed Shaky's custom Kernal and I couldn't get past the tegra note 7 screen. - at this point I probably could have saved it but doing anything other than what happens next.
Flashed 4.4 stock Rom which has to have reset the Recovery and Debugging is now off.
Do not do what I did. Brick. Any ideas? I can still get into bootloader which is unlocked but my computer no longer recognizes it. Pretty much lost hope on this one. Surprise me if you feel inclined.
I've been trying to sideload via externalSD, the stock 4.3 ROM from the "Tegra Note Discoveries" thread. It actually gets halfway though installation then fails for reasons I can't begin to understand. Most likely because it's rooted and I'm flashing a stock rom. If anyone can find a way to flash the stock Kernel and 4.3 rom I would be grateful.

In the recovery environment , ..... you are inside the ram disk of, whatever recovery you are running and root status of your system ROM doesnt matter .
Since from the 1st post you have recovered it to the point where you can access the recovery, I think its just matter of getting the correct backup re-installed.
You can request someone with same Branding ( there are 6-7 avent, XOLO etc ) to upload their cwm backup ( minus data, cache ).
Lack of developer / geeky user community is what you get when companies lock their bootloader under disguise of Warranty n stuff.
I havnt been able to gather the courage to play with TN7 like i do with my Nexus7, nexus 4 and Xperia J . ( XJ has some great XDA community btw even after closed BL)

Yea I jumped in the deep end without doing enough research. I have rooted and installed custom ROMs on my android phone without issue but I've never messed around with kernals or had to dig myself out of a device stuck in boot-mode. Instead of learning about a device then modding it, I forced a situation where I modded now need to learn how to fix it.
As novice as I am, still working on getting the correct drivers installed to sideload a backup. My computer will not recognize the ADB device in the stock bootloader but when I boot into recovery it does recognize it so there is definitely a driver issue there.

I think more like a dozen brands of TN7.
You should at least tell your brand, would make it less mysterious.
Advent has a stock 4.3 install install via APX mode (although you seem to be only able to use it once, then it locks
the nvflash stuff).
I apologize I have the EVGA Tegra Note.

you are lucky ... this thread has many posts of the same branding EVGA..
Top posts & stickies also have a AIO post about recovering a unlocked BL device.. download and do it OP.
Hi Guys. Tablet is working fine now. I used multiple files from multiple sources to get this going. Here were the commands to get me back to stock. Obviously there was a lot of playing with commands etc that I cut out. I truly believe this device is unbrickable. I was just stuck in a bootloop.
in short, the issue was with the boot after a kernel flash. The TWRP recovery was flashed back to stock.
Got the drives from SDK download because I'm not slick enough to be able to do it myself.
In fastboot, make sure you have the fastboot file in the folder with your boot.img , recovery.img
fastboot boot boot.img ----got me out of the bootloop temporarily without flashing anything unnecessary
fastboot flash boot.img, flashed the boot.img from Vega Note 7 source files that are out there, I recommend every download those now.
fastboot boot TWRP_recover.img -----messing around be led me in a good direction
From there, I installed the below file from XDA User e8hffff
Forum post and links: forum.xda-developers.com/showthread.php?t=2580287
Backupfile name: productionbl_signed_tn7_114gp_2923379__4.3.zip
I believe that was a full backup of a 4.3 Evga Tegra Note 7 stock. This really helped me out a lot.
Thanks everyone for the help. You can see by the very few command that got this device up and running I am a total noob but I'm figuring it out little by little.
If anyone is in a similar circumstance in the future send me a PM and I may be able to assist you.
Some basics - About bootloader, kernel, recovery, rom, /system and some other partitions.
There are many noobs out there and sometimes even I am one. Two days ago @Closed Force asked me, where I know my stuff from and why things are like they are... So I finally decided to write this little guide about how Android devices basically work and what are the special things about our G2.
If you find wrong facts or any other mistakes (grammatical, language, contentwise), please bear with me. That's how I read it in the forums. And of course not everything written on XDA is correct. So please tell me by PM, or by posting in this thread if you have additions, corrections or any other concerns about this OP.
Where I got to know all this stuff? Reading, reading, reading. I first started modding my old HTC desire like 4 years ago. Since then and even before I'm reading. Mainly here on XDA but also on some german forums and wikis. It might have taken me easily 200 hours or more. So the only way to learn for a newbie (and everyone else too) is reading.
Personally I own a D802 variant. I know about some things that were different in details for the US variants, but things should be right as they are.
Finally thanks to
@d00lz for some extra research/additions and a quick read through.
@Art Vanderlay for some additions.
So let's get started:
When you press the power button, your device will load the Bootloader. The Bootloader afterwards wil load either the Recovery Image (recovery.img), the Kernel (boot.img) or the Download Mode Bootloader (laf.img), depending on the keys you press. At the moment there are three different bootloaders; The Jellybean one, the KitKat one, and the new Lollipop one. Not one of these Bootloaders can be unlocked yet, so there are workarounds which allow us to boot custom ROMs (specifically Kernels, but more about that later) and custom Recoverys. At the beginning there was the Jellybean Bootloader. The Developers (sorry, I don't know which ones) found out how to get around the locked Bootloader pretty early. They called this workaround Loki. It's intergrated into nearly every ROM except the ones which require the KitKat Bootloader (but that's usually not the reason they don't support the JellyBean one). Anyways, soon the KitKat update came and so did the new KitKat Bootloader. Sadly, LG patched the Loki exploit with this new update. However, the Developers found a new way to get the Bootloader booting files which weren't signed by LG. They called this workaround Bump. Bump basically imitates the LG signature so the bootloader thinks this file was really signed by LG. Obviously this workaround works with the JellyBean Bootloader too. In the Lollipop Bootloader this exploit has been closed and no one knows how to get around the new Bootloader, yet. In conclusion to Bootloaders, as long you have a working Bootloader, your device is not dead. You can usually recover it in some way.
The G2 has about 30 partitions (for a more detailed explanation, look here, thanks @d00lz). Each partition has its own purpose. One of them is the Recovery partition. Imagine: A Recovery partiton and a working Bootloader are everything you need to keep your phone working. It's kind of an Operating System in itself, completely independent from Android or anything else stored on your Mobile. The great thing about the Recovery partition is that it's so small that it can be run directly in the RAM. This means it's capable of modifing EVERY goddamn partition on your Mobile, including the Bootloader and the Recovery partition itself (means you can flash a new recovery.zip in your current recovery). Attention: if you are using the Recovery with a 4.4 KitKat Bootloader, it needs to be a Bumped Recovery. If it isn't bumped the Bootloader realizes that the Recovery is not genuine and generates a "Secure Boot Error".
Same thing goes for the Kernel. The Kernel is located in your /boot partition (found gzipped inside your boot.img) and is loaded by the Bootloader when you only press the Power Button and you let your Mobile boot normally. This is the reason why your Kernel also needs to be Bumped if you want to get your system booting on a KitKat Bootloader. When 4.4 KitKat came out, most Developers switched over to using LG's 4.4 KitKat sources for their projects. After a while it was realized that 4.2 JellyBean sources were a lot more reliable for AOSP baed ROMs. This is why most AOSP ROMs use the 4.2 JellyBean Bootloader and the 4.2 JellyBean Kernel sources while Stock based ROMs use the 4.4 KiKat Bootloader and 4.4 KitKat Kernel. There are different Kernels for AOSP ROMs and for Stock based ROMs. This is because Stock Kernels support some ROM functionalities that AOSP ROMs don't have, for example; Knock Code. (Note: Knock Code isn't open source, which is also another big reason why it isn't available for AOSP ROMs.) So there are huge differences between Stock and AOSP based ROMs/Kernels. The Kernel (without factoring in the AOSP and Stock issue) can be switch at anytime you want.
Now about the /data partition... All your personal stuff, including Apps, System Settings, App Data and so on will be stored there. The reason why you should clear it every time you change the ROM is that there are many variables set by the ROM you are coming from. Your current ROM may have some tweaks the new one doesn't have which means the new ROM doesn't know how to handle them which leads to crashes and instability.
Now let's get to the ROM... Having a 4.2 JellyBean Bootloader and a 4.2 JellyBean Kernel doesn't mean the top layer has to be 4.2 too. Most of the AOSP based ROMs are based on Googles KitKat or Lollipop sources. And this is true KitKat or Lollipop, with all its functionalities. Those huge version differences cause some problems in development. No wonder some things do not work properly today, but it's still the best working combination at the moment. It's kind of a wonder how it works as it is, but let's be happy with it. I'm very curious how AOSP ROMs with Lollipop Kernel sources will work. Your ROM and your entire existing Operating System is found in the /system partition. This is why it's the main partition which is modified while flashing. Which partitions will be modified and (how) is written in the updater-script file of the file you're going to flash. Theoretically, running a updater-script of a ROM which changes the Bootloader (/aboot partition) can brick your device. That's also the reason why you should only flash stuff made for your device only!
As already said an updaterscript can modify every partition through the recovery. All ROMs bring their own kernel, so you basically don't have to care about it, except you want to use a non-bumped ROM (with kernel) together with the KitKat bootloader.
Finally something about the baseband/modem (these terms are interchangeable). I noticed that the Developers or rather the Original Posters sometimes don't know which baseband the user should use with the ROM. In earlier days the wrong baseband could make the ROM bootloop. Today most ROMs work with most basebands. It's obviously best if you stay on the one you currently are on and just flash another one if something doesn't work (auto-rotation for example). The baseband can be flashed at any time and is on it's own partition.
Okay Download Mode time. It's part of the laf partition (laf.img). This partition is used by LG and it's PC software to recover the phone and bring it back to Stock. It's a partition in itself, but not completely independent of the Bootloader. It's because of this that you can of course have a fully working Bootloader, but a dead Download Mode. This means you will not be able to flash a .KDZ/.TOT file the next time you are in big trouble! ^^
Okay to wrap up I should mention the EFS partition. The EFS partition stores your device's IMEI (and the serial number as far as I know) of your device. NEVER wipe it. With a empty EFS partition you can use your mobile as a brick, ok maybe you can use it as a media tablet, but that's it (WiFi still works, @Art Vanderlay tested; see below).
Again: if you got questions/additions/correction or see a mistake, post below, or PM me, I'll edit this post...

Nice write up Sunny. You can credit Dan Rosenburg for creating loki. I can also confirm that wifi still works without modemst1 and modemst2 aka efs. My phone suffers for this thread.
@Sunandroid
Perfect! This was all I was looking for. Now I finnaly understand how my G2 works and I'll most likely not need to ask more "noob questions" in this matter.
But I would like to ask some questions because I've left with doubts after reading the OP.
As long as I have /recovery/ and /aboot/ working, I can recover my device exclusively with software. Is this right?
I've concluded that you need /aboot/ to be able to enter in /recovery/ and with recovery you can mess up with any other partition.´
How can I tell if /modem/ found here is compatible with my device? Are all /modem/ partitions the same in the same models? For example, I'm from Portugal so I have a Portuguese D802 LG G2 (if I type its IMEI in a site, it recognizes it as portuguese). If I flash a German D802 modem or English or even American, considering that they are all from D802 would they work flawlessly with my device?
Why does /modem/ cause auto-rotation to work? What exactly is /modem/?
I have a backup of all the partitions in my laptop (made via TWRP). But what happens if I accidentaly lose my /efs/ partition? Can I flash another phone's /efs/?

Glad I could help you this way...
about /aboot and /recovery: yes you are right. It is even better, if you have an intact laf too. That's the download mode. But as long the other two work, you can fix the laf partition easily. But if you get into the situation, that only those two are working, better don't flash a bootloader (=/aboot). If it's the wrong one your device is bricked.
Aboot is the key to your device. Everything else is fixable. At least with a little bit of knowledge and time. But better don't try it out.
No, the modems are not all the same. There are (sometimes depending on the branding) extremely small differences between the basebands/modems. I personally never had the problem, that I couldn't get any connection at all. But that's not fatal. Just flash another one and try again if it works. Btw: I once made a test in some german forums with different KK basebands. I'm not sure anymore, but the differences were minimal and I think killed my connection totally.
If you loose your efs stuff, your device is a brick with extended functionalities. The IMEI and some other data stored in the efs partition is worldwide unique. So you can't just pick the one of another phone (except the other G2 is bricked or whatever). You need the IMEI for general network connection. So it will still boot up, but you won't be able to text or call anyone with this phone.
Okay ^^
So this is a full backup of all the needed partitions right? http://prntscr.com/76edu4
Should I convert these files to something like .img to be able to flash in the phone just in case I get something that disables my TWRP access?

Yeah, I guess so. As long as you ticked everything when you backed up (with blastagators TWRP!; the official one doesn't allow to backup the efs stuff), this should be fine.
Well you could. But tbh I have no idea how to convert those files into .img files. But it isn't necessary anyways: It's unlikely that you loose the efs data on your phone unless you brick it somehow. If the phone stays recoverable, The first thing you are going to do is: flashing bootloader, laf and boot.img. Then you will go back to stock through the download mode. Once you've done this it's an easy one to install twrp again and restore the efs backup. No one is gonna flash ~32 partitions by hand. There are "easier" and more usefull ways to recover the device.
Oh and btw: no backup contains the bootloader, laf and boot (recovery developer don't implement this for some reasons). But this doesn't matter. The only thing you really need is the efs backup (which partitions exactly you can see here). Everything else isn't unique and can be extracted out of kdz files and restored this way.
Edit: the two partitions mentioned here are

Oh btw i tried your (noob friendly) no download mode, no recovery mode ..... using slax,
when i typed ls /dev/sd* it's only showed my PC (only one sda) and there is no sdb, not even one
Weirdly i can access TWRP, but i can't make any custom rom boot,
Man this is frustating
I have a phone, G2 D802 Int., which probably has a corrupt EFS partition. I guess the owner broke it flashing incompatible things into it. As a result of the corruption, ESN/IMEI is lost. It shows null. But very interestingly, the EFS partition mustn't have been wiped because by chance of a boot among a hundred, it shows up the ESN. If by chance you come across to ESN, everything operates normally. And if you reboot the phone, ESN is gone again..
I managed to make recovery work again, by upgrading the phone to lollipop. (It was another time I came across ESN.) But no download mode, USB is never identified (unkonwn usb device), USB modes cannot be changed, unless by chance you come across, USB debugging is no more either.
I was thinking to backup some necessary partitions from a working phone of the same variant, but since it's "unknown device", I cannot query it as a disk. Neither it works in Ubuntu. ls /dev/sd* doesn't show the phone. It even doesn't show the working phone.
Any idea about how I can fix the corrupted EFS partition?

I was thinking to backup some necessary partitions from a working phone of the same variant, but since it's "unknown device", I cannot query it as a disk. Neither it works in Ubuntu. ls /dev/sd* doesn't show the phone. It even doesn't show the working phone.
Any idea about how I can fix the corrupted EFS partition?

Yes I know that, but since I cannot take the device to USB debugging mode, it's not the first step I could take. "USB device descriptor is failed", this is what I get when I plug the phone.

So what is the current state of your phone? You have twrp installed. Can you push stuff through adb when you are in the recovery (this is pretty important, since we maybe can fix the download mode this way)? Does it boot into android?
@Sunandroid, device operates normally except the voice call & data, since these depend on IMEI. The phone boots normally, and everything is working, only the IMEI shows as "null". Additionaly, cannot enter to download mode, no recovery installed, original recovery is working, which is used to do a factory reset only. No USB debugging, it says "USB device descriptor failed". Thus no adb.

From what I've read about this issue (device descriptor...) just now, it is not software but hardware related.
I've heard of people solving that issue but I couldn't manage to do. Gave the phone to my customer back after 4 days. Importer service put the phone out of warranty and offered him a motherboard replacement for 75 $ and it's pretty fair I think. After all it comes funny when he says he's gonna file a case about returning the phone and take his money back. Well, it's up to him to end up with nothing in hands after months of waiting for a case.
Shortly, this file has been closed without a reasonable solution.
Thanks for your effort @Sunandroid.

Glad to hear that. Hitting the thanks button doesn't hurt.
OK so I rooted this thing a long while back with the help of someone who i no longer talk to. I'm not entirely sure what all I have on it. Basically I'd like to either flash a newer rom on it or simply put it back to factory with a factory image of I think its 5.0.2 may be the newest one or at least the newest one i could find.
When trying to just put a new rom on it it always fails. SOmeone told me because the factory image is running the original android version that came with it and the new roms need to have the factory more recent. Like I said I dont fully understand all of this. I'm not a computer idiot, just havn't researched or spent much time learning about rooting and what not.
ANyhow I've got Team Win Recovery Project v 2.4.4.0 on it. I dont know how to get to the factory image or rom to update it. I'd post a picture but I'm not allowed to yet apparently.
Basically need some direction on how to get either a new rom working or just throw the whole thing back to factory.
search for "nexus root toolkit" it'll do everything you need

I already have a bootloader on there from a rootkit tool when the tablet was first released. Would a new toolkit just overwrite everything on it, or woudl it clash with the bootloader already installed?
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).

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 !"
