New to Samsung devices, but just need to make sure - Samsung Galaxy S7 Edge Questions and Answers

Hello all,
This is my first Samsung device, the Galaxy S7 Edge Dual sim (SM-G935FD) bought from UAE.
I used to install TWRP and root every android phone I had before, so I am still not sure whether to root this one. I already have the files required for rooting, but I noticed that there are 2 ways of rooting:
1. Using Odin to install TWRP and then from there install SuperSU.
2. CF-Auto-Root.
What is/are the difference(s) in both methods?
My other question is: I read that rooting will trip Knox, and there is NO WAY to get it back to normal even flashing the original ROM. Is that the case?
One last thing, I am now stuck in the download mode (turned off the phone, pressed "Volume down", "Home" and "Power"), I did that just to check the info on the top left (model and warranty void...) but I cannot seem to restart the phone even by pressing the power button for more than 20 seconds, how can I turn the phone off then back on?
Thank you
*****EDIT*****
Regarding my last question (stuck in Download mode), pressing the same combination got me back to start the phone normally

Cf-AutoRoot will root your phone but then you will have to put your recovery on also usually flashed with Odin anyway or an app if it's working for the Galaxy S7... Twrp plus superuser will root and you'll have the recovery installed.... They both will trip your official (0x0) knox and make it (0x1) custom.... You can always go back to stock rom and get OTA updates but your knox will remain at 0x1......this is supposed to void the warranty but depending on where you live it won't make a difference.... Also if you want to flash roms and mods and kernels just use the twrp method and if you just want root and to be able to use root permission apps use the Cf-AutoRoot.... As of right now I haven't rooted because there aren't to many Roms available... I'm sure I will cause I miss titanium backup and the ability to get rid of all the bloat ware (especially Facebook & Microsoft ****).... The phone runs great without root and battery is excellent.... The last reason I was waiting was Samsung pay won't work with tripped Knox counter.... I live in the US but have the international 935F... So it doesn't look like this variant will support Pay anytime soon.... Probably gonna root when development picks up a little....
*edit*... Always have a stock rom just in case saved to your computer just in case... That would of saved me lots of freak outs and headaches years ago... Now it's the first thing I do before Rooting or flashing anything to my phone

Thank you for the detailed reply.
I made a research yesterday on Knox (as I said, this is my first Samsung device), and I just wanted to make sure that I understood things properly.
So now after reading, tripping Knox will disable Samsung Pay (I do not have it in my country) so that is not going to make any difference. But, what about paying using the fingerprint sensor in Google Play, will it stop working if Knox is tripped? I also use the fingerprint sensor to login to my mobile banking app (instead of typing the password every time I want to login), will that stop too? I guess not but again just to be sure.
Thanks a lot once again.

I know when I rooted my S6 all the fingerprint stuff still worked so I dont think it will make a difference... Im not sure with the S7 edge but I would think it would still work cause all of those require a typed password before you use your fingerprint(1st setup only) Then use your fingerprint there after... .. Doesn't have anything to do with Knox

yep, it all still works. just Samsung pay & private mode.

Galaxy S5 G900F XXU1POJ1 - Need help & advice ROM/Root

Hello,
as thread title says, I need some advice from professionals here for my new Galaxy S5.
Well it's not quite new (almost 1 year) but never rooted it or flashed it, so I still got OS (original system) by Samsung.
I am a pretty amateur on such stuff. First I need some advice what to do: Rec & Root or flash custom rom?
Followng things are important to me:
The System has to be stable and fast: no lags, no crashes, no errors (I do not expect 100% stability, since not even OS is 100% stable, but it has to be at least stable as OS or even a bit more)
I need features and nice widgets (Rom must also be afordable to other apps and widgets, I 'd prefer Samsung OS widget)
I need good quality on camera (preferred OS cam software and features)
Good signal and GPS (Good and fast GPS is a MUST!!, as I use often Navigon when I travel with my car)
Good video player and galery app (Preferred Samsung OS Galery App, but video player can also be different than Samsung OS Video Player if its working fine)
What I do not do with my phone:
I do not play games
I do not read e-books
I don't understand the purpose of KNOX! Do I need it really?
Here are some details of my Smartphone:
Model no: SM-G900F
Android version: 5.0
Modem version: G900FXXU1POJ1
Kernel version: 3.4.0-6364590
Build number: LRX21T.G900FXXU1POK5
Securitysoftware version: MDF v1.1 release 4 / VPN v1.4 Release 3
I would be greatful if someone could give an advice if it is worth to flash a custom rom and if yes what rom based in what moden and kernel versions or if a simple root with recovery install is enough?.
Thanks in advance
Regards
Hi @GordonSpace.......
Most of what you said in your post leads me to believe that there are many things about the stock OS that you are happy with. That being the case, the old adage 'if it ain't broke, don't fix it' comes to mind.....meaning (for now) you might as well stay with stock. If you start flashing CM custom roms (for example) you will lose that look and feel.
On to your question about Knox.....
In a nutshell, knox is based around an 'eFuse' which will trip or blow as soon as you modify your device. This eFuse CANNOT be reset. Samsung are, in some cases, denying warranty repairs on devices where knox has been tripped.
So basically, as soon as you flash CF Root or TWRP to gain root, your warranty is void (Samsung normally provide a 2 year warranty on their devices). Tripping knox will also prevent future 'over the air' updates. So even if you unrooted your device you would be stuck with the version of the OS that you have on your device. Finally, tripping knox will prevent your device from connecting to 'business enterprise secure' servers. So if you currently use your phone on your employers network, this will no longer be possible.
If you still want to go ahead and forget about knox, this is the easiest way to gain root......
Follow exactly....
1) deactivate 'Reactivation Lock' (can be found under Security in Settings).
2) copy SuperSU zip to your device.
3) boot into download mode.
4) Odin flash TWRP 2.8.7.0 (specifically this version).
5) DO NOT allow phone to boot, (uncheck auto reboot in odin and if necessary remove the battery as soon as the TWRP flash has completed) then.....
6) boot directly into recovery. (Vol +, Power & Home button combination)
7) flash SuperSU zip.
8) boot device as normal.

When you have root access, you can get Titanium Backup from the playstore and freeze/delete the 'bloatware' that comes pre - installed on Samsung firmwares.
That will then give you the stability of the software designed for the phone coupled with the look and feel that you like, but without the resource hogging rubbish that most people with unrooted phones have to put up with......

Hello keithross and thank you for your response.
I use my smartphone only in private.
However it still has 11 months warranty by Samsung. Another Idea I had was to sell my Galaxy S5 as it is (OS and Knox) and buy another smartphone.
However what would be your recommendation for a new smartphone?
I was thinking about LG or HTC. But I'm not sure about to purchase a "famous" brand device or just a cheap one like Mobistel, Huawai and such.
What is a nice smartphone to have it root / flashed?
Regards
Kiri
I have about 9 months of warranty left on my phone....but I was able to root without tripping knox.....simply because I rooted before I allowed my phone to update to Lollipop (I rooted with Towelroot while running KitKat) then debloated, and customised the stock firmware.....so I have my phone as I want it, and still have knox intact.
The S5 will probably be my final Samsung smartphone, but as of this moment, I haven't given much thought as to what I'll replace it with. I'm half tempted to keep it beyond the end of it's warranty and start trying out custom roms at that point. It does everything I want it to do, so why would I need to replace it?
On the other hand, if i did replace it, I'd probably stay with one of the well known brand names.....The chances are that they'll have more dev support than the less popular makes of device....but I won't waste my money on any more flagship devices, I'll probably look at the 'upper midrange' devices as they'll (by that time) probably have similar specs to my current device (the way technology is currently advancing, they may even be superior to the S5)......

CyanogenMod
I decided to flash cyanogenmod snapshot
1. However I do not understand the difference between klte and kltedv rom (kltedv = vodafone. does that mean my provider has to be vodafone?)
2. TWRP or Cyanogen Recovery?
3. Do I need to install a diff Kernel version?
4. Anything I should take care about before I flash? (something special about Samsung drivers, kernel, odin etc...?)
Thx for your support.
1....In all honesty I can't answer having never flashed custom to my S5.
2....TWRP recovery over Cyanogen recovery....Every time. Cyanogen recovery is little better (if at all) than stock recovery.
3....flashing a different kernel isn't strictly speaking necessary....unless you want to be able to change processor clock speeds and voltage and apply various other specialist 'tweaks'.....
4....after rooting (but before flashing) make a backup of your EFS folder (critically important) it contains, amongst other things, your IMEI number. If this folder becomes corrupted, you're in a whole world of hurt....
Back up any personal data that you can't afford to lose....things like photos etc.
Make sure you have a copy of your current firmware available....If it all goes pear shaped, you'll possibly need it to recover your phone.
The version of Odin that has most compatibility with the S5 is v3.10.7 though other versions *should* work.
Get hold of and install the Samsung USB drivers on your pc....They come bundled with Kies available on Samsung's website. (If you install Kies, you will need to use task manager on your pc to kill the kies processes prior to flashing anything with Odin).
Use the usb cable that came with your phone when connecting it to your pc.
Make sure you've disabled your firewall and antivirus before attempting to use Odin.
If you need any more help just let me know by commenting below.....

Hey thanks mate. I rooted my device with CF autoroot via odin. I read that CM13 with Android 6 is as a stable version out now. Probably I am gonna flash it. However, I have a question with my current root of S5. Currently the wifi passwords are being save as an encrypted hex key in the wifi_supplicant.conf file. However I would like to use an app that saves and shows my wifi passwords, but unfortunately due to the encryption of S5 it's not a help for me. Any recommendations what can I do to save the real PW instead of the encrypted key?
Sorry fella....The tech aspects of your question have gone right over my head like an international Jumbo Jet....I have no idea what you're even asking about, let alone how to solve it for you. Your best bet would be to create a thread specifically for this question.....you will probably get more views for that thread than for this one.....sorry mate....

You should already know the passwords if they are your routers/APs
I don't know my passwords. The thing is, that sometimes we go to some cafés and such where I have saved the PW of the router, but sitting with friends some of them do not have it to connect with wifi. Thats why I am asking if there is a possibility to view the passwords I saved in my wifi connections (not as a hex key but the true passwords). Anyway.. thx for help. I guess thats Samsung OS. Hope it won't be with CM13 like this.

Samsung Pay still not working after restoring to stock through ODIN

Got my S7 yesterday, played around with root, and decided to go with a stock experience for the time being so I can use Samsung Pay and MST (blasphemous, I know). I used ODIN to restore back to stock, verified KNOX counter wasn't tripped, and went on setting everything up.
I installed Samsung Pay and launched, only to run into the access denied message you would see if you were attempting to open it with a rooted device. Any thoughts as to what could be happening?

I would make sure you followed the return to stock instructions in psouza4 thread (http://forum.xda-developers.com/ver...-to-notes-root-install-xposed-unroot-t3411039). I flashed through odin yestererday and took the pf2 update that was available when I was done. I am able to install and access Samsung pay. What all did you flash in ODIN?

Resolved! Actually, it was my strict adherence to the instructions that led to the issue - the instructions only tell you to flash AP, CP, and CSC back down to PE1. Which was fine and dandy, but my BL remained at PF2, which is the reason why I had issues loading Samsung Pay. I was afraid that I had either tripped the mythical physical e-fuse somehow, or my phone was blacklisted from Samsung Pay servers - fortunately this was not the case! Once I updated everything back to PF2, Samsung Pay was able to load.
Help Galaxy s7
Hello friends, I made the root process in my S7 GALAXY, but the direct method cf self root, now my knox is 0x1. Is this with your method, I can return to the original state knox 0x0 and able to use the Samsung pay ???

Sorry but there's no method at this time to reset Knox back to 0x0. The method of root that was posted here wouldn't trip Knox which is why when flashing back to stock they are able to use Samsung Pay again.
how to trip that knox again? and how to check knox state? I had installed stock samsung s7 edge India ROM latest but now smart tutor apps is gone (that i intalled from playstore) and samsung pay is not working

SD Fix permission and root

Hi guys, I just got the samsung Galaxy S7 Edge (G935F Exynos) but I miss the Root permission.
I have two question:
1- Its possible to fix sd car permission on 6.0.1 without root?
2- can i install CF-AutoRoot or other root without invalidating the warranty and to flag the Knox?
I have no need of custom recovery but only the Root
Sorry for stupid question
Thanks
1. Just lockate sd card in every app that needs using it... when the stock android file manager opens press 3 dots and show sd cards, then choose the sd card.
2. you can root by flashing twrp with odin and cf autoroot with twrp, if you have an international gs7e, i hear all USA are locked. Read more and find a guide here or in Youtube. Also there is no way to not trip knox, if you flash smth custom with odin it will change for ever to 0x1. In a lot of country 0x1 don;t void your warranty, just need to be insistent and prove that root could not cause this problem. Also root is not needed as it was before... want no adds install ADHELL from google play, it works rly well, still testing it and battery looks ok. Tasker can do close to all things now without root using autotools or autoinput, not as good as with root but still an option, reselling rooted phone is a lot harder, of you can dont say anything to the buyer if he knows nothing about Samsung device...

Does installing stock firmware reset knox?

Just wondering if installing stock firmware using Odin resets knox. I of course tripped it without even knowing what it was, and it looks like my banks mobile payment option requires knox 0x0 to work. I've looked at lot of posts on here with regards to resetting the knox counter, etc, but they are pretty outdated and most of the files required to accomplish it are long gone. If anyone could point me in the right direction it would be so helpful. I don't care about having root, I'd prefer to stay on the custom rom I'm on, but if that's not possible I'm willing to go back to stock. I noticed a lot of the threads are asking how to keep root while resetting the knox counter, but I just want to know if installing stock rom will do this for me.
Did a little digging and it looks like its impossible to do. Oh well, mods can close this thread.
Knox so important?
Even my note 3 got 0x20 count i will no bother if no abnormality happen..just carry on and live with it
I think it's only possible on the Exynos version, not on Snapdragon.
As for your bank, maybe it only detects root, NOT knox 0x1
So, you can try Magisk root method instead of the traditional SuperSU, because Magisk can hide root from a couple of apps that detect root, like Google Pay

Issue is due to tripping your knox.
How can i fix it
Once Knox is tripped that's it there is no 'fix'
At the moment the only way to fix is replace motherboard or buy a new phone
Just means you cannot use some Samsung related apps like secure folder,Samsung pay Samsung private browser etc.

Eh, that's not a bad thing... There are plenty of way better alternatives on Gplay or F-Droid
There are 3 potential ways around it:
1. Custom ROMs based on stock that software set the Knox to be 0x0 (not tripped).
2. Use Magisk and hide your root on that app in particular.
3. Download a modded APK of Samsung browser that doesn't check for root
