S6 G920F - 5.0.2 Engineering Bootloader (Root on 5.1.1 without tripping KNOX)

Hi
/* I DO NOT TAKE ANY RESPONSIBILITY FOR WHAT HAPPENS TO YOUR DEVICE *\
/* PROCEED AT YOUR OWN RISK *\
This method will allow you to root your S6 on 5.1.1 with UniKernel (NO KNOX TRIPPED).
Engineering Bootloader for SM-G920F 5.0.2: Link removed
UniKernel: http://forum.xda-developers.com/gal...d-development/kernel-stockmod-kernel-t3100395
1. Install Samsung USB Drivers if necessary.
2. Put phone into download mode. Power phone off then press and hold Volume down, home and power keys at same time until you see warning screen then let go and hit volume up one time.
3. Plug phone in and wait for drivers to install if necessary.
4. Open odin you should now see phone’s modem port highlighted in blue.
5. Click on BL tab and select correct sboot.bin that you downloaded above. Then click start.
6. When phone comes back on power off again and put into download mode.
7. Open odin again and this time select AP tab and select UniKernel file and click start.
8. That is it!!! When it comes back on phone will be rooted. To verify that knox has not been tripped go back to download mode and it should still say KNOX WARRANTY: 0 (0X0000)
NOTE: ITS POSSIBLE THAT THE FINGERPRINT SCANNER MAY NOT WORK, SO IF YOU CAN LIVE WITHOUT IT USE THIS METHOD OTHERWISE DONT.

Very interesting, definitely going to a keep an eye on this one. I'm not brave enough to be the first to try though!

You will definitely not be the firts to try this. It is an old guide, the first one was on the g925f model thread. I rooted my galaxy s6 g920f this way, and i didnt trip knox. I do not use fingerprint, so i dont care it is not working. Definitely try this.

Does anyone know if I restore to factory after this root method, will the finger print work again?

No, is necessary flash a stock firmware with ODIN.

Please say this works for AT&T variant on OF4

@UltraGamerHD Will you build the needed files for other Samsungphones like SM-G900F, too ?
Would be suuuper nice !

I didn't build the files AT ALL. This was leaked and I obtained this from Reddit.

WOW, great! Sadly that I have already tripped it

I'm new to Galaxy's, coming from Nexus. Is is possible with this bootloader to install a custom rom without tripping Knox? Or is it just for rooting the stock rom?

If i'm not mistaken, flashing custom recoveries or ROM's will trip knox no matter what. You can look into Flashfire by Chainfire for a better idea of a alternative .

You are mistaken, flashing any custom rom will not trip knox as long as you are on engeneering bootloader. I change roms a lot, my knox is still at 0x0, just keep the bootloader.

Oh, my fault. I was confused for something else..... Good to know tho.

Think this would flash onto a G890A OR does anyone have an ENG SBOOT for this device?

Will this work on AT&T variant??

This "engineering bootloader" ... what is it, a special bootloader for internal Samsung devs?

Thanks for requesting the engineering bootloader from me in order to copy and start a new thread about the same thing that I already have on my own guide...

Hello. Where I find Engineering Bootloader for SM-G925F?

Galaxy S4 USC Unroot?

Hello,
I have a galaxy s4 on 4.4.2 that I rooted using kingroot a while back. It is a US Cellular SCH-R970. Knox has not been tripped. Under device status it says the phone is custom. This means I cannot update to 5.0.1.
My question is, how would I return the phone to official status without 1. Tripping knox, and 2. Keeping all of my data. Also, do you know if I can root with kingroot once I get on 5.0.1.
Baseband is R970TYUFNK1.
Thank You!

Hi,
Flash a proper complete stock firmware via ODIN. Firmware for R970TYUFNK1 is R970TYUFNK1 (itself).

SamMobile, Samsung Updates, or via SamFirm app. I usually rely on SamFirm.
Edit: As long as Re-partition and NAND Erase All is unticked on Odin, it should be fine.
PS Note: You can install newer firmware over your current firmware via Odin, too.

It would be wise to backup and wipe data before flashing. Otherwise you might encounter problems.
And do not use kingoroot to root lollipop. It used to not work or cause problems. Use cf autoroot method, if your device is supported.

Problem is cf auto root trips knox.
If I flash R970TYUgoh2 would I keep knox at 0x0 and all of my apps? Then I can root with kingroot.

Having knox triggered is just a bunch of crap from Samsung to scare you. Unless you actually use knox. Or if you are afraid from losing your warranty. Which is also crap, because, whilst reading the warranty file, I saw that it won't cover water damage, it won't cover a broken screen and a bunch of other stuff. The only thing it covers is actual hardware failure. And if the phone is new, that's pretty unlikely. Even if it does fail, Samsung has no way to see if knox has been triggered until they change your hardware and are able to boot up the phone. At that point they can't refuse to take it into warranty service anymore.

Wow, that warranty is a load of ****. Also the phone is over a year old so I'd doubt it's still under warranty anyway.
What would you recommend to make a backup? I don't have fast Internet at all (300 kbps down), so I think a local backup would be more efficient.
Thanks for all the help! Have a good Christmas!

OK I flashed 5.0.1 successfully, all my data carried over. Now I need to root. Do you know where I can download the cf autoroot files for jflteusc or sch-r970 on 5.0.1?

There is a cf auto root thread in the general section. Or you could simply google "cf auto root s4".
Make sure to read the thread.

OK I have that installed now. I'm looking for some new roms and found that there are practically none for the sch-r970. Could I just use roms for the gt i9505 (jflte) or would this not work at all? I'm looking for a 6.0 rom.

JDCTeam AOSP has your device model on the support list. They have Lollipop and Marshmallow.
But you should be able to use other GT-I9505 roms too.

Under their downloads section they have 2 untagged files (doesn't say GSM or cmda) and one GSM (won't work). Will one of the untagged roms work?

Marshmallow roms have been split into gsm and cmda, due to changes in the radio. You have a cmda device.
The initial build of aosp marshmallow was for both cmda and gms devices. The newest build (the december 24th build) is split into two. Gsm version has been released but cmda version needs more work.
So you will have to download the 6th december build which was unified. Or the lollipop builds.
Lollipop builds have a different thread and a different link.

Root s7edge, exynos G935F

Hello to all.
I would like your kind advices and opinion on the following matter.
I have a stock s7edge, exynos variant (G935F).
I still have one year of warranty.
After the latest security updates and the fact that I can no longer install S8 apps, it got me thinking about rooting the phone.
I am fairly experienced in rooting phones and installing roms. As a matter of fact, all my previous phones are now rooted and updated to 7.1.2
My question is the following:
I do not want to install a new rom. I am happy with the stock one (at least for now ). I just want to root the phone in order to be able to have access to the system files and replace the apks etc.
Is it worth it?
If yes, how can I root the phone? (any guide with recovery files included etc?)
If I root the phone, what things will I miss and not be able to do? (Do I just lose KNOX and Samsung Pay?)
If I want to go back to unrooted state, is it easy, and how can I do it? (any guide with stock recovery included etc?)
Your kind assistance and opinions will be very much appreciated.
Thank you.

Mate wrong thread.

Yes, sorry about that. A big thanx to the devs for moving it to the right thread.

So, I made a research and I believe that the best way to root my s7 edge is using Odin, then flashing the latest twrp recovery (3.1.1-0), and then by entering the recovery, to flash the latest SuperSU zip (v.2.82).
Do you agree? Or is it better to use Odin and then flash the CF-AutoRoot??
Also, if I want to un-root the phone, do I just have to flash via odin all the stock firmware files (CP, CSC, BL etc?). Will that also bring back the stock recovery and delete twrp?
Also, will the KNOX counter be triggered even if I unroot and return back to stock using the above method?
Final question is what will I miss if I root the phone? I suppose KNOX and Samsung Pay. Will everything else work as normal? Will I have any problem with the camera's performance?
I thank you very much in advance for your assistance.

Hi
There is a guide here - http://www.droidviews.com/install-twrp-root-galaxy-s7-and-s7-edge-on-nougat-g935fxxu1dplt/
make sure you follow this guide EXACTLY
This is different from other phones!
The only thing you will miss is Knox and Samsung Pay correct everything else will work along with Magisk (hides root from apps such as AndroidPay/banking apps).
If you were to install a custom rom i suggest Superstock (current v2.8) As you can probably tell from the name its an improved stock with battery tweaks/camera tweaks etc
Yes when you flash TWRP KNOX is tripped and there is no going back what so ever even if you flash stock firmware and remove root knox will still be tripped so wave goodbye to knox.
if you did want to go back to normal yes just flash official stock firmware with odin this will remove root and twrp.
(knox will still be tripped though)
p.s you could skip supersu install if you are going to root via magisk instead
if you are unfamiliar with magisk etc i highly reccomend just installing a custom rom (such as the one i mentioned earlier) which comes with magisk already installed

First of all thank you so much for your kind reply, contents of which are noted.
To be honest, if I will flash a new rom, my first choise would be a full s8 port rom, like Konghloi's.
The only thing that worries me is what you said about KNOX not reseting even if I unroot and return to stock. I don't really care about the app itself (I think that even samsung will stop its development in order to propmote "secure folder". I am more concerned that I will lose my warranty since the dealers will know fore sure that the phone has been rooted at some point in the past.

understood, having personally tried all the s8 ports already i reccommend ambasadii's S8 Port (Konghloi is a great Dev but past experiance the ROM's are infested with bugs) I'm currently dual-booting Roms and have ambasadii's as my secondary ROM
About the warranty... if you read the fine print samsungs warranty isn't worth a great deal. it will only cover you for an electrical or mechanical fault that is common with the device. (which if your savvy enough you can fix yourself anyway) it wont cover you for any accidental damage drops/water/cracks etc...
Also you can still take your device to an other dealer to fix your phone for you, they don't care what you've done to it (with payment ofc) just not Samsung.
you really have to weigh up both options
personally i think the chances of device failure is slim and easier/quicker to fix as long as its not an expensive fix like the LCD breaking (which if you dropped it and it broke your not covered anyway)
and the pros of rooting and custom roms heavily outweigh the cons of loosing knox and voiding warranty.

Didn't have chance to watch the whole video just skipped through bits but all he did was flash stock firmware... this will not reset your Knox counter and not give you warranty . He probably did not even root his phone lol all he did was update it. Also I think there is a way to root without tripping Knox but as soon as you flash twrp or custom Rom Knox is triggered.
It will unroot your phone but it will not get your warranty back once it has been voided. Knox is an e-fuse once you break it there's no going back unless you replace hardware
Edit: Here is some info from Wikipedia:https://en.m.wikipedia.org/wiki/Samsung_Knox
Here is some answered questions about Knox

i want help unrooting galaxy s8

Hi
i remember unrooting my galaxy s6 by flashing stock rom with all its files, i mean the csc file and the others ? , but i dont know if that method is still working because of the new security updates, knox and whatnot
am really bad at this, but i just wanna be able to use bixby and it says i have to update my software
so, how is it done ?
thank u all

Just flash Stock Samsung Rom.
Knox can't be changed however. That's gone forever.

True
in quick you can't
root access can be removed by flashing stock firmware but as knox is tripped when rooting, there is no way to reset knox counter.
if you flash stock firmware, no root access of course but you won't be able to use Samsung pay, Samsung health, secure folder and samsung pass, and this is permanent and forever, as these apps check knox status and not root access. I suggest you to keep using custom rom as you will be able to use apps like samsung health and maybe samsung pay

Depending on your rom, you should still be able to use bixby.

What variant you're on?

Sorry, I don´t get it. When you boot up an unmodified StockRom everything is working out of the box. Do you mean a Custom Rom based on stock with SamsungPay etc. working? Please elaborate.

you want to sell the phone and have already tripped knox?
if so, the answer is no. s-health, samsung pay etc all require knox 0x0 to work on an unmodified rom. i had the same problem.

If knox is tripped you won't be able to use Samsung Health, Samsung Pay, Secure Folder etc. even if you flash a stock firmware image.
If you flash a custom rom the device will not be able receive OTA updates.
Unfortunately there aren't any fixes for tripping KNOX.

You could flash an official Samsung Rom and get automatic OTA Updates, or flash a custom Stock Rom (Batman Rom, Renovate Ice etc.) and get some extra features, but your brother would have to update manually.
In both cases everything knox related will not work.
Flashing a offcial Rom via Odin is probably the easiest solution.
