Confirming what is possible w/ a sm-g9601U - Samsung Galaxy S9 Questions & Answers

Been trying to follow up on the latest with this particular model and just want to verify my understanding:
I CANNOT flash a recovery or custom rom to this phone as the US bootloaders are locked (there may be some ways but it still doesn't yield full flashing/capabilities)
I CAN still root this phone
I CAN still de-google & debloat the phone through root access
I realize these are not all model particular and more root basics so the first is the most important question and the rest I am validating my understanding as it's been a while since I've daily drove any rooted device let alone one custom flashed. I think the s2 was my last w/ Cyanogen lol
Thanks to all!

You cannot flash a custom recovery but you can flash a GSI (which sort of counts as a ROM), the other two are correct. And yes, flashing a GSI will have tons of bugs so be aware of that.

[Q] Unlocking Bootloader and Rooting

Hey guys, sorry if this has already been answered somewhere else but I couldn't find it anywhere.
I bought a Galaxy Nexus a couple weeks ago and am loving it (except for battery life) and am interested in rooting it. But I have a few questions first:
1. What is the difference between unlocking the bootloader and rooting a phone. I know what unlocking a bootloader is, but I don't know much about rooting.
2. If I unlock and root, will I still be able to get updates from Google directly wihtout issues? Like, will I get the 4.0.3 update whenever it comes out even if I'm rooted?
3. Will my warranty be voided if I unlock the bootloader?
4. And if I do root it, what ROMs do you guys suggest I use? Which ones are the smoothest in performance and give the best battery life and customizations etc?
5. There is a new unlock/root tool made for the SGN, shown here: droid-life.com /2012/01/04/simple-galaxy-nexus-lte-rootunlock-and-unrootre-lock-tool-released/
Is it as effective as unlocking and rooting manually or does it have some drawbacks since it does everything for you automatically? BTW, thanks to whoever made that tool.
I know these are dumb questions but I'm new at this, so please bear with me. Thanks for any help in advance!

1) I have an app called All About Root which should answer the majority of all basic questions and even some advanced technical ones regarding root.
2) Yes, if you're still on stock and dont change/modify any of the stock apk/framework files. Once the OTA update finishes, root access will be removed and a stock recovery will be reloaded. Will have to fastboot flash the custom recovery back and set the permissions back on root (permissions are a topic in All About Root)
3) Depends on who is covering the warranty or another way to put it, who/where/how device was purchased.
5) I would always recommend learning the manual method. Once you load the android-sdk, which is needed for many customizations, the unlock is a simple command and learning adb/fastboot will be very useful in the future for most operations.
Hope that helps! I'm sure others will chime in with their opinions and experiences to cover any gaps I might have missed. Good luck!
1) Unlocking allows you to modify the kernel and flash custom roms. Rooting allows you root access to the OS. Root is the equivalent of an admin in windows, but in the context of android it gives you write access to the full device. Basically it allows you to access lower level system functions (ie droidwall is a gui for iptables which is a firewall).
2)My understanding is that if you unlock and root, you'll be running a custom recovery (clockwork). I'm not sure if that means you won't see the OTA or if it'll just revert to stock or it may not work at all. Perhaps someone else can explain, but frankly when you get to #4 I don't see any reason why OTA updates are relevant.
3) I think the bootload can be relocked so even if it does void the warranty it can be reversed. Whether or not they can tell that it has been unlocked I don't know, and if they wanted to find a reason to deny a warranty I'm sure they could find one whether or not it's unlocked. I'd be surprised if they denied it though since the nexus devices are important because they can be unlocked.
4) I've used Axiom pretty much since the day after I got my phone. Most of them are all the same 4.0.3 core just various modifications to 'improve' the experience. The one other rom I'd look at is kang's because it's based on CM9. Kernels are another issue from there - I've liked both leankernel and franco's. Note that you should check out the forums over at rootzwiki as their dev area seems more active than around here. The kernel is the main source of battery and performance boosts.
5) I would recommend attempting it manually. The most difficult part imo is getting the drivers installed and the device recognized by adb. From there it's just executing a single line to unlocked. Unlocking will wipe your data. I'll say it again...unlocking will wipe your data. I used superboot myself, but if you're going to a custom rom then getting root access is really only needed temporarily to get clockwork installed - any custom rom has root access already. Here's a link to superboot. I *think* you just execute it from your computer (its a batch file) and it will root the device for you. I'm not sure if it installs clockworkmod so the first thing you should do after booting is download rom manager and reflash recovery to be sure. Then you can use clockworkmod to move to a rom.
Happy flashing.

Before Rooting Question

I just got this phone. Android 4.2.2. I was wondering if rooting is still possible. I know that there are issues with unlocking the bootloader like, we can't. So can I still root and have the rooting goodies? If so, can you direct me to the correct method of rooting? All the methods I can find include unlocking the bootloader first and I don't know if I can just skip that step or not.
Thank you for your time.

To answer your question you need to unlock/s-off your phone to root it, I would recommend running the rumrunner tool, installing a customer recovery and then install a custom rom. The reason I say install a custom rom even if you want to remain stock is because you can get a stock rom without any bloat. Most of the bloat apps on the HTC One and pretty much any phone, run in the background as soon as your phone starts, this eats battery life and performance. For a stock rom check out Santod040, he has a good stock rom released, personally I like NuSense and ViperOne they are both very solid roms.
Read this thread - http://forum.xda-developers.com/showthread.php?t=2473644 it is the Rumrunner tool. I believe as long as you DO NOT UPGRADE to 4.3 you can still root/unlock/s-off, after you unlock/s-off you can install whichever rom you like without worrying about losing the ability to have root access.
You will want to get into the bootloader to check which OS version you have and then download the corresponding version of Rumrunner.
Edit:
Be sure to backup your whole phone as soon as you install a customer recovery. After the backup is complete, save a copy on your computer. There will be times when you are tinkering with your phone that you will need to get your phone back to a factory state, you can use a RUU but in my opinion that is more complicated process and you have a higher risk of something going wrong compared to simply restoring a backup.
Okay. Thank you. I will look into this.

SM-P600

Hi All
Let me start with few good things here You guys are amazing helping and providing tweaks for us:good:
I am Nexus user. I have Installed Custom Recovery, Flashed ROMs and rooted my Nexus 4 and Nexus 5. This is my First Samsung Tablet. I have waited enough for Nexus 10 (2). I finally bought SM-P600.
I was trying to find an Guide with links for Unlocking bootloader and Updating firmware and then flash Custom recovery for this but coudnt figure it out
I have been reading lots of things about Knox and counters related to it.
Can anyone Please help me find answers straight.
1) Any Rooting and Custom Recovery tools or ADB commands without Hitting the KNOX counter {Just In case IF I wanted to return it} If not then which one you recommend ?
By the Way I found few posts related to Rooting Which has confused me more. I used to use Chainfire SUROOT:
Rooting using CF-AUTO Root
Universal Root de la Vega
2) If I Root and want to use Stock ROM of SM-P600 will all apps work normally or any known issues with it ?
3) Is Odin any tool which everyone is taking about ? I am not sure about it Can you provide any links to its dev for more info. Found it about in a Post to return to STOCK ?
4) Are these ROMS and apps Odexed or Deodexed ROM?
5) Any Dependencies for Firmware and with any of the above questions. I mean In Universal Root I saw they were talking about certain version of firmware. Also Should I update the latest firmware and do a Nandriod backup ?
6) Also read that once KNOX counter goes up, I wont get any OTA ? My Plan is I will use it till next Nexus and will give it to parents with stock ROM. If I am using I can always use an Custom Rom and get updates. But for parents I want to return it to stock so that they can easily update when OTA is available.
I would like to make one more suggestion to MOD's Please Pin the Guides like the Rooting and stuff like Return to Stock which are quite common and useful so that its easy for newbies( aka for Samsung) like me.
Thanks
Zaib.
1. This is not really a single question with a single answer I think vaguely what you are asking is if you can root without tripping knox?
Nope. Not at this time.
2. If you use CF-Auto-Root you'll likely find that the vast majority of applications keep working without issue. Of those that don't, a handful you can manage back to a working state with various tweaks, but there are a few that are probably gone for good. You can basically kiss all the Samsung hub apps goodbye, these will start claiming they are not supported in your country even if they were working perfectly prior to rooting, some may continue working for a short time after but eventually something leaks and your access is cut. Screen mirroring will no longer work though this can be fixed with a small zip file flash. OTA updates are also gone.
Forget all the talk about 'triangle away' fixing any of this, it hasn't for me.
3. Odin is a tool that is able to flash firmware files or parts thereof to your device. Heimdall is an alternative suite of applications, while there is a GUI for it, it seems fairly hit and miss on Linux these days, I've never had much luck with it, on the other hand the command line tools work perfectly fine.
Once you trip Knox, there's no turning back! You won't lose your warranty in any meaningful way, but you may end up having to argue about it and drag in government regulators to get your tablet repaired free of charge depending on the dealer response.
4. I don't think this is particularly relevant to the SM-P600. My subjective opinion would be to stick with the bog standard Samsung ROM. If you want cool themes there are a multitude of launchers, Xposed takes care most other things you might ever care to tweak.
5. You have one choice. CF-Auto-Root. Backups are healthy.
6. True, but you'll still be able to flash via Odin so it doesn't really mean much of anything. Once you trip Knox, you can also kiss OTA updates goodbye as well.

Hi. I was s-on, rooted with twrp 2.8.7 on lollipop. went stock, bootloader and rom, updated to MM, wanna do root again. I remember I unlocked bootloader before - was it relocked in the process of going stock? How to check if it is unlocked? other steps 2 and 3 are quite clear by redpoint73
EDIT: yes the unlock was still intact. Managed to get twrp, made backup (thanks for advises), and when it prompted to install or not root, i decided yes... Stuck on boot logo, managed to restore. Now searching for 2.66 supersu and will try to root via twrp again. my m8 is not GPE. fingers crossed

The only way for it to become locked/relocked again, is if you do so manually.
The bootloader screen will tell you the bootloader status: LOCKED, RELOCKED or UNLOCKED

The automatic root in TWRP isn't updated for MM, therefore doesn't work, and as you see results in no-boot.

You rooted your M8 succesfully? @edvinb
I wanna root on marshmallow , i wasnt rooted at all, so i just unblock bootloader, install twrp then flash that supersu 2.67 ?
Is this the correct procedure ? @redpoint73
Stock, S ON, locked bootloader, M8y 2.5 ghz asian version
yes, proceed, I successfully rooted my htc
So, after twrp you installed the newest supersu from redpoint link? @edvinb

SuperSU 2.65 is marked as "stable", although any version after that are probably fine, as well.
http://forum.xda-developers.com/apps/supersu
Alternately, if you installed TWRP 3.0.0.0 or later, the built-in root will probably now work correctly on MM. This was not the case at the time of my last post (Post #6 above) where TWRP 2.8.7.0 was the latest version (and not updated to properly root MM).
true, it didn't boot when i tried supersu through the old twrp.

Hi. I've been looking for a dummy's guide to rooting my m8. I'm in New Zealand so I'm guessing I have the international version, though I don't actually know how to check. I'm running marshmallow and sense 7. Redpoint73 Can you tell me if the brief instructions from your post on the first page will gain root for me without bricking my phone? I want to be able to install some of the flashy roms from the android development section. Thanks

You won't brick the phone rooting or flashing a ROM. At least, the chances of bricking are so slim, its probably less likely than bricking from an official OTA update on a stock device. If you start messing with s-off mods, that is a different story. But s-on (and that is all you probably need) its nearly impossible to brick.
Yes, the process I described briefly in Post #3 above will work for just about any M8 variant, with the exception of Verizon.
Vomer's guide is pretty good, although not updated: http://forum.xda-developers.com/htc-one-m8/general/vomerguides-m8-bootldr-unlock-s-off-t2800727
You only need to follow the first parts of the guide that pertain to unlocking the bootloader, and installing custom recovery. And for those parts, I think the only thing that is outdated, is that (depending on your current firmware version) you should probably use a more recent version TWRP: https://dl.twrp.me/m8/
You actually don't need to root to install a custom ROM. Once you have custom recovery TWRP installed, just put the desired ROM on the phone, do a default wipe in TWRP, and flash the ROM.
For more specific help, and determining what M8 version you have: figure out how to use fastboot, then do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
If all this is new to you (and it sounds like it is) my advice is to start reading the available guides and starter threads. I don't personally like "dummy's guide" approaches. Reading and understanding fully, before doing anything, is a much better idea. You actually learn something that way, as opposed to "step-by-step" guides which do the opposite (you accomplish the task, but probably don't really remember or understand what you even did).
And if you have specific questions, just come back here; and we'll be happy to try and help.

Thank you so much for the detailed reply. It's given me the confidence I needed to go ahead with this.
I've had some experience. A few years ago I rooted and s-offed a htc sensation. Problem is its so long ago I've forgotten most of what I learned. Hopefully it'll come back to me as I get into it.
I wasn't aware you could flash roms without rooting. Would you be able to tell me what advantages rooting would allow me over simply flashing a rom?

Some folks like to stay on the stock ROM, but have root (such as for using apps that require root). Other than that preference (to stay on the stock ROM), I wouldn't say there are any "advantages". In the past, this setup (stock ROM, but rooted) may have allowed official OTA updates. But that is no longer the case, as even unrooting will still cause an OTA to fail due to "modified" software. Forcing you to restore the appropriate stock (never rooted) ROM in order to OTA. So that negates any advantage of staying on the stock ROM (and rooting) for OTA purposes.
Flashing custom ROM is for folks wanting something different from the stock ROM (and that sounds like your goal). All the custom ROMs are pre-rooted. So you have root, once you flash the ROM.
@redpoint73: i have a HTC one M8 eye. I try to flash twrp and it says success

Can I flash Lineage OS on my ATT Note 10+?

Hello everyone,
It's been awhile since I've been on Android and now that I'm back it doesn't really seem to me like there's any use of flashing roms now as most phones are useable. The only reason I can see is debloat with or w/o root. Anywho, my question I'm trying to ask is am I able to flash Lineasge OS on my Note 10+ N975U? I tried looking for my answer but all I run across is people requesting to flash ATT firmware for Volt LTE to work and etc.
Thanks!

In order to flash a custom rom you need to be able to unlock the bootloader. Same applies with rooting the device or flashing a custom recovery.
Since we can not flash a custom recovery, root the device or unlock the bootloader then your answer is no.
