I have a quick question regarding rooting my G920F with the engineering bootloader. I am currently on Android 5.1.1 stock unrooted.
I understand the bootloader is 5.0.2 and that the fingerprint scanner won't work because I am on 5.1.1 and the bootloader is 5.0.2.
If after rooting I install a 5.0.2 samsung based rom will the fingerprint scanner come back to life as the bootloader will be 5.0.2 as well as the rom.
Yes with a 5.0.2 Rom the fingerprint will work again.
But keep in mind...wrong thread for asking this question!
So the finger print scanner will come back if i install any 5.0.2 samsung based rom using TWRP
While we're at it - if I install 5.1.1 ROM stock rooted on that 5.0.2 engineering loader, then flash stock bootloader/recovery/kernel, could I, in theory, regain access to the fingerprint scanner while retaining root? I figure I can hide root from Samsung Pay, get V4A and Xposed and be happy lol.

Samsung Pay and Google's version of it are different. Google's version requires no root, Samsung's version requires you to have KNOX 0x0, which you cannot change after you have rooted.

I am running 5.1.1 stock (no root). Is it definately correct that if I install the Engineering bootloader and UniKernel then flash a 5.0.2 rom then the fingerprint scanner will come back?

If you are not on the Engineering bootloader now, you cannot downgrade to that bootloader.

Thanks. So are you saying the method of flashing the engineering bootloader for anyone that has OTA upgraded their S6 to 5.1.1 is no longer working now?

It started when I tried to install a CM11 update. I did not see that was only for KK BL, then I tried to revert to stock rom(using RSD lite) and install the old version for the JB BL again, but my wifi still not working(or working only when it wants lol).
Anyone could help me?
I tried to flash a lot of different roms, even reset with RSD, but the issue stills. I don't know what more I can do
Thx for the att and sorry for my horrible english...

If you are rooted, the OTA will fail, so you have to flash back to stock before taking OTAs.
If you are locked and you take an OTA, you will lose access to whatever exploit was patched. In the case of going from JB to KK, the original root (Saferoot I believe) won't work. However, Towelroot will work for those that have locked bootloaders.
However, if you are rooted and on the latest official KK, then you can unlock your bootloader and then, no matter what OTA comes out after that, you will still be able to root your phone without the use of an exploit like Towelroot. Instead, you take .zip image of the SU app you are using and flash it in TWRP or CWM recovery. No exploit needed.
Towelroot is only for those that don't have an unlocked bootloader and it's an exploit (a security issue) within the specific version of the Android OS. OTAs patch these as they are released, which means another exploit has to be discovered in order to achieve root for locked bootloaders.
So, right now, if you are not unlocked, you better unlock on the initial KK release because the latest soak test does patch Towelroot and the bootloader exploit. You've been warned.
All the other threads are kind of scrambled, so I made this thread to discuss all things marshmallow.
OTA
The OTA is rolling, many of us have gotten it, and those who haven't should get it very soon.
WHAT'S NEW
-Wifi Calling
-Android 6.0.1 Marshmallow
-Good Lock Support
-Battery Improvements with Doze
-Now on tap
-New app icons
-1 more bloat app
DOWNGRADE STATUS
I am happy to announce that after taking the Marshmallow OTA update, I have had NO ISSUES downgrading to PB1 using Odin.
ROOT
Root is here - only for unlocked bootloaders. Go to muniz_ri's thread for more info.
Locked bootloaders will probably never get root - Samsung have implemented dm-verity in the kernel - so modified system partitions will bootloop. The only way to get around this is systemless root - which requires a mod to the boot img, which is not possible on locked bl.
STOCK TAR
The stock tar is not available yet, but we're patiently waiting
UPDATE: It's on SamMobile.
PF4
Another OTA is rolling. This just fixed a small issue with unlock, and nothing else.
Post any questions/comments about MM below.
thank you very much for the information and work PD1 Root.
Good luck, I read ur all staring discussion, u were desperate. I hope we will find the easy step by step solution with no errors.

There won't be root for 6.0. As of 5.1 and continuing with 6.0, Samsung implemented a kernel check for any system modifications. The device will not boot when system is modified. A custom kernel is required in order to override the kernel checks which is out of the question for locked boot loader devices.
If you need root on this device you will have to stick with 5.0 or lower.

Then how does jrkruse's note5 port work on locked bootloaders and still allow root - while being 5.1.1? does it still use a 5.0 kernel?

Oh, dm-verity. Or, damm-verity
Us with unlockable bootloaders should still be able to root mm, right? I dont see why not, the supersu zip can disable dm-verity in the kernel on unlocked BL.
Can you please confirm this?

Sorry, meant incorrect. The kernel cannot be modified on a locked BL device.
I've already emailed in regards to the kernel source for PD1.

Ok jrkruse and muniz_ri have rooted it. Unlocked bootloaders can go get root now.
I think this is my exit from the VZW S5 community. I've had enough constantly trying to battle all these locks.
How do I go about getting rooted/unlocked again if I set my phone back to stock to take the OTA. Do I flash PB1 firmware then downgrade to Lolli? I'm confused at this point, but am not horribly concerned if I managed to lose unlocked capability....

Always need root just to install custom roms . If we can install roms without root , then we don't need root anymore ( I am still lost ). Now I can wait for custom 6.1 roms.
Its not ideal but at least you dont have to go through the whole reroot process each time you want to change roms. And you can still flash zips etc in safestrap.

Can we run and use apps which require ROOT access?
I'm a bit confused though. Don't custom ROMs come pre-rooted???? So wouldn't flashing a custom ROM which is pre-rooted....... remain rooted?

You cannot have a rooted MM rom with locked bootloader because to have root requires a custom kernel which locked bootloaders cannot flash. It doesnt matter if the rom is prerooted or not! Stock Boot.img means no root. You cannot run apps that require root with these roms All this method does if give you some options the biggest option being the ability to flash zips. and change roms with out having to odin back to stock pb1 then reroot then. Try the stock MM rom I posted. Once installed you can flash a debloatzip or a knox removal zip or delete apps from safestrap with the built in file manager If you dont like you can always downgrade back to PB1

@jrkruse How does this work?
Based on my knowledge from reading this, it seems that the kernel finds the checksum of the system partition and then only boots if it is unmodified.
Shouldn't modifying the system partition in the slightest bit throw this checksum off?
Also - modified kernels CAN be flashed on locked bootloaders - just not via Odin. They only won't boot though >.>

Will this method work with FF? Haven't used SS since my SG4 days.

I got one to try. I have tried it so I know it works
Download this rom
Download my Patch
In safestrap do a manual wipe. Wipe Data,WipeCache,Wipe System
Install Rom
Install patch
This rom Does not flash system.img so you dont need to install safestrap it will stay installed
After patch is installed wipe data and wipe cache and install MM Bootloader zip
Reboot it will take 15 to 20 min to boot
Now you will Have A Note 5 port with working theme support

hey what can i do im on the MM firmware but i flashed something and now my phone just stays at the samsung logo with a blue led light what can i do it wont but up past the samsung logo screen
I prefer the speed and performance of marshmallow on the S7. Where are the correct files I should flash in Odin and which version of Odin should I be using to flash Android 6?
So apparently the camera isn't working after downgrade to 6?
Not something I'm willing to deal with unless the issue has been solved.

Any help with proper step by step in downgrading my factory unlocked phone would be appreciated and any root links as i havent done it in years.

thats not true
You can downgrade any version bit loader by flashing the combo firmware and the rooting combo firmware then flash stock nougat system image its basically what the root method is for Rev11/B. If you are just on nougat then you would have to get the combo firmware that matches the bootloader version you have because if you flash my rev11/B root method you are forever stuck on that bootloader and can never use nougat again or have oreo root as there is no eng root boot.img available for oreo root on rev11/B bootloader

Is there any way to downgrade binary 6 to 3 or just downgrade android oreo to marshmallow (ik its the same thing)
If someone ask "why?" touchwiz
It is not possible to lower the binary. This is what it was introduced for.
If the phone allows you to unlock the bootloader and flash TWRP and Custom ROM, then you can try to find a ROM based on an earlier firmware version, but it will no longer be a fully trusted firmware.
