Now on Note3 N9005 there are some members or Dev's that advise to tick or mark the Phone Bootloader Update in ODIN when we flash a full single Rom whit Bootloader in AP or PDA.
But them not explain why they advise that.
I not understand why and I need known the reasons for this. Single Yes or Not are not enough for me.
I'm on my 11º Samsung device, I used some Odin versions from 1.83 to 3.09 and the Odin Multi Dowloader V4 also.
I flashed already many, many Roms by Odin and...
I Never ticked the PHONE BOOTLODER UPDATE... NEVER... NEVER...
Why now here?
Is it because the Knox Bootloader? But the S4 Mini LTE + Mega 6.3" LTE + N7100 3G have also the Knox Bootloader but anybody advise to tick the Boot Update. (N7100 is now on 4.3).
I think:
1- We must not tick it if we flash a new full Bootloader.
2- We must tick it if we flash one Mod to Update the Bootloader installed.
3- Or we must tick it in some special devices for some reason.
Please people help me to understand this but whit good explanations.
Thank You

To upgrade to Kitkat, you'll need to upgrade your bootloader, if you're upgrading to another 4.3 then its not needed

For me not true.
I flashed from XXUDML2_OXXDMK3 Android 4.3 to XXUENA6_OXXENA5 XEO Android 4.4.2 Kitkat without tick Phone Bootloader Update and all well, no issues. I never ticked this and I'm now on XXUENB3 Kitkat.
I made full wipe data+cache+dalvik and format system on customer recovery before flash Kitkat.
I continue doubting from that. Sorry

N900->> I've just upgraded to 4.3(MK2) to 4.4.2(NA6) without BL update tick.
That's a fact.
What is the big point? To tick or not to tick?
I'm really sorry, but I miss the importance and use of this thread.
For me ( using N900W8 ) it didn't made any difference whether I tick it or not. Flashing from 4.3 to 4.4 and vice versa didn't give me any problem.

To You may be, for me not.
If the tick is for this:
2- We must tick it if we flash one Mod to Update the Bootloader installed. (from OP).
I'm afraid in this case, if Odin flash the new BL over the oldest without wipe this one, in some cases we can have issues.
May be I'm in error but I'm thinking.

You could have updated and then re-rooted again by now
Think its possible if you download a pre-rooted rom.
Yes i know the other possibilities, but i don't want to lose my data and install everything again, thats why i want to know if it is possible to update without losing root and wiping. With flashfire it was possible to that on marshmallow but i dont know if it wil work if i update to nougat

Unfortunately no, you'd have to Odin back to stock in order to take the updates.

I have seen that it is possible with other phones by updating with flashfire but i want to know if it works fine for the s7 too...
Still no solution -_-
I upgrade between nougat firmware using flashfire and just put the SuperSU/Magisk(switched to Magisk recently, both work) zip in the flash chain. So it works. Not sure about marshmallow to nougat though.
Steps to update....?
Would you be so kind as to provide us the steps to updating with stock ROM? I have a rooted S7 with Magisk/TWRP that I would like to update (without losing root) to the latest stock ROM from Samsung.
It would be greatly appreciated!

Note: You still need a PC to flash the bootloader and modem with Odin, but that might not be necessary for smaller updates. This may not work too well coming from MM to Nougat.
In Flashfire, add the AP file only from the ROM. Next, add a HOME_CSC file from your current CSC and make sure it says "Process cache". You can mix HOME_CSC files from any region with newer firmware marked for any other region. Extremely old HOME_CSC files will likely break the newest firmware though. Make sure to turn off EverRoot if you intend to use Magisk, in which case you should add the Magisk zip to the flash chain.(don't use v13 yet). Add any other mods you typically flash here (eg. I have a zip which disables tima in build.prop to keep encryption working) Also make sure "Preserve recovery" is on. Set the device to shutdown when done. (Download mode won't work when booted into by Flashfire. It's a bug) Next boot into download mode and flash the BL and CP files from the firmware package with Odin and reboot. It might boot back into TWRP, in which case just boot into system.
You're awesome, Curtis!
Though I'm still scratching my head: so even though I have Magisk/TWRP already installed on Nougat (to gain root access) and I wish to update with the latest Nougat ROM from Samsung that was just posted on sammobile 2 days ago, am I correct in saying that I would STILL have to install Flashfire and EverRoot for this process to work?
Thank you for your tutelage and patience.

EverRoot injects SuperSU, basically as if by CF AutoRoot. Magisk has it's own rooting solution, which despite being compatible with SuperSU will likely fail safetynet if Supersu is installed. Also I have no idea which order it will flash them in so I can't predict the outcome here...
Basically. If you want SuperSU use EverRoot. If you want Magisk, disable it and use the Magisk zip. Both will grant root access when done.
Edit: Got Bootloader Files just now. Will include it in my upcoming custom ROM
Will keep it short. Nobody wants to read big stuffs anyways

Here u go guys,
The Ofiicial Oreo firmware R16NWG935FXXU2ERD5
- Its a TWRP Backup
- Contains UNTOUCHED System,Baseband and boot image.
Steps:
- Extract zip to your External SD
- Reboot to TWRP
- Wipe system, data, internal sd etc etc (what you do usually when flashing a rom)
- Restore> R16NWG935FXXU2ERD5
- Flash no verity zip
- Flash Magisk
- Flash your Country CSC (Use S8 Port CSC for now)
-Reboot
Download link : https://mega.nz/#!URswBJ5A!ThOBn4u7dZYQGEo6BueKCtL-BS1gqzsLgMWlSaYrJ-c
This is only for people who dont want to wait for official OTA and for Devs who wants to make a ROM now
The official firmware might get uploaded on sammobile after 2-3 days
The backup is untouched so everything is present in this (bloat and useless apps too)
Debloat apps with titanium backup and report back if u face any issues.
Make sure to debloat SecuritylogAgent. It keeps bugging you that unauthorised actions have been detected and stuff lol
If your knox is intact or dont like dumps then follow Rifek's Guide

Your Warranty is void if you install TWRP once in your phone. Installing TWRP changes knox counter to 0x1.
It stays 0x1 even after flashing official firmware later. So dont install TWRP just for this update. Wait for official release!

Flash TWRP Backup then
If u flash Official Odin firmware and update to Oreo U cannot downgrade bootloader! So no more Nougat Firmware flashing.
Also you may not be able to flash your country official firmware via Odin (Bootloader Version Lock).
So play it safe and Use TWRP Backup from this thread.

Odin will not let you flashback to a previous boot loader version, you have to do it through TWRP. So either flash the nougat firmware with TWRP first or any nougat based rom, then flash nougat via odin which will remove root and TWRP.

Are there any instructions for this?
Will secure apps (Banking etc) work again after removing root?
I was under the impression you could via Odin if OEM unlock was enabled, without needing TWRP or root. https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-downgrade-android-oreo-8-0-t3821495
edit: As for banking, if you go root then flash back to stock you should have no issues. Even if you stay root, things like Magisk will hide root status from apps and pass safetynet. Your biggest issue would be the loss of Knox, which voids warranty and breaks some Samsung apps.

Ok so listen, it can be done as i said but it's not easy. The choice you have of course before attempting this is to just install a android 7 custom ROM? many nougat ROMs are just stock with the bloatware removed and the boot-loader version isn't checked during flash.
Here's another way to go back, i can't guarantee it will work though i haven't tried it on an S7.
Downgrade to an older firmware with an older bootloader even if one keeps the newer bootloader on his device.
So what's how's it done?
Download the firmware file (.tar) which you want to downgrade to and open it with an archiver application (7zip). Extracts all the files to a folder and repacks them again in a .tar file but leaving every file out which ends in .bin (e.g. sboot.bin etc.). This .tar file can now be flashed like any other firmware file via Odin and it should run through it without any problems.
Hope this helps.

Hello, i would to ask about how to downgrade to the earlier version of the stock ROM
I already download the correct country code, variant and everything else but when i click start in Odin
It says that cm.bin fail and the process is canceled, how to fix this issue?
Thanks a lot
SM-A750GN with XID country code, here is the firmware that i use https://www.sammobile.com/firmwares/galaxy-a7/SM-A750GN/XID/download/A750GNDXU1ARIE/241618/
and this is my device firmware now A750GNDXU2ASB4
or is it not possible to downgrade? any help around this as to not void my warranty if possible
There could be a couple of things:
1. You could be using an outdated version of Odin
2. You need to re-download the firmware, try searching updato for your firmware
3. Maybe the current/latest version of the firmware installed on your phone locks your boot loader to the current version (binary version matches the boot loader)and that is why you can't downgrade
What you could try (definitely at your OWN risk) because if things go wrong you can end up with an expensive paper weight:
1. Unpack the firmware with 7zip, remove the file (cm.bin) then repack to tar with 7zip
2. You can try to flash just the AP and CSC

You can't downgrade because the bootloader is protected by Rollback Prevention, the only way (maybe) to use Oreo is to flash TWRP and wipe system data and use any custom Oreo ROM.
If you want to know about Rollback Prevention then there is a attached pdf from the Samsung Technical documentation

AFAIK there is no Oreo custom ROM for this phone on THIS forum

You can't downgrade because the bootloader is protected by Rollback Prevention, the only way (maybe) to use Oreo is to flash TWRP and wipe system data and use any custom Oreo ROM.
If you want to know about Rollback Prevention then there is a attached pdf from the Samsung Technical documentation
