I have the S8+ Snapdragon. If I want to keep root, but flash the latest firmware including security updates and baseband etc, what files should I download and flash? Is it possible to do so over flashfire?
Thanks in advance!

You can flash AP CP and CSC in FlashFire, but you will need to remove Knox apps and from build.prop, do any debloating, etc yourself. BL has to be done in Odin, but don't flash the stock BL if you're rooted, or you won't be able to boot.
Or you can just download and flash my s8+ rom that's going up tonight and get the latest version, prerooted, with modern firmware and tons of add-ons for free ?
It will be posted later tonight, watch the ROMs board for it!

If you want to remove root:
- Use Triangle Away to reset the binaries and system status to official
- Unroot from within the superSU app
- Flash the rom with Odin
- Data factory reset
If you want to keep root:
Use Mobile Odin Pro to flash the new rom and keep root. Check inject superSU, Everroot and the other option.After it reboots do a data factory reset (root will stick btw).

No it's not safe nor recommended. If you had done a search you'd find dozens of threads asking and answering this question in existing threads. Accepting an OTA update is likely to break root and sundry custom ROM features.
You should refer to the custom ROM support thread where the developer will either tailor updates for your ROM. Or at least power users will discuss their effect on the ROM and how to best apply an update to your particular ROM.

OP is talking about flashing a full stock rom with Odin as i understand , not about getting or installing OTA`s as he is on a custom rom atm
..
Quick background. So my note 4 is currently on 5.0.1 boe1, stock rooted knox flag tripped so I cant update via OTA to 5.1.1 which is fine, I'm already readying myself for a manual Odin update
Question is that if there is a 5.1.1 firmware avail on my country for my provider, if I flash the stock 5.1.1 firmware does it also flash the 5.1.1 bootloader or will it retain my 5.0.1 bootloader? I'm pretty sure it will also update the bootloader but wanted to ask anyway to confirm.
Main reason for asking is that I know you lose root when you flash stock firmware via Odin. I'd still want to attain root after upgrading to 5.1.1. Not sure if there are any methods to date to root on 5.1.1 bootloader, or if its safe to flash the 5.0.1 bootloader after the 5.1.1 stock firmware flash.
TIA for those who would answer. [emoji1]

Simple bro. Don't forget to backup your data!!!
Poland 5.1.1 comes with 4 files including bootloader, modem, csc and system. Country or provider means nothing for it, it will work anyway. So, here are the things you gonna do:
1-) Flash Poland 5.1.1 with odin (be careful to place all files in correct section in odin!!!)
2-) Enable usb debugging from developer options
3-) Flash twrp with odin
4-) Lastly, flash which 5.1.1 rom you like, all of them are rooted now :good:
Bumping up since 5.1.1 is already avail on my country. Wanted to know if flashing the 5.1.1 firmware would wipe the device or will it be just an upgrade.?Haven't tried flashing an official firmware on top of an official stock (lower version).

It won't wipe your phone data, it will be like an upgrade.
Secondly tripping knox does not mean you will not receive OTA. As long as you are fully stock and when you check the system status in settings and it states 'official' you will receive the OTAs

Thanks! Yep, realize that now. I believe the reason I can't receive OTA is due to the custom recovery I've installed. Will try reverting to stock recovery first to see if I can OTA upgrade. If not, will download the full firmware and flash on ODIN.

The ROM might still consider your device to modified, You may have to flash stock from Odin and then check the status, if it still says modified then a factory reset might be required.
My Note 3 (SM-N900, Exynos) is currently booting CM 13. I'm gonna sell this phone, so I need to flash the stock Touchwiz firmware that the phone came with out of the box i.e, 5.0 Lollipop.
1. Since my phone runs Marshmallow right now, should I flash a Lollipop bootloader before I flash the stock Lollipop Touchwiz firmware?
2. I'm from India, and I'm a bit confused because there seems to be two firmwares for my region - INS and INU. Which one should I flash?
3. I've been told I should use Odin to flash the firmware, so is there any chance I might brick the phone? or lose the root status?
I'd be grateful if someone could help me out with the above questions. Thanks!
Flashing a stock rom with Odin will lose root. No need to flash anything before flashing stock with Odin.
Use Samsung phone info app from the play store, find the pda and csc. Then match stock rom pda/CSC to the phone.

I only see the info about Product Code, Baseband and Bootloader. The PDA and CSC fields are just blank. What do I do now?
Flash the firmware for your network or the original network .
Boot into download mode, confirm the model, and flash a rom from sammobile.com.
Is it possible to flash an EU ROM on the US version of the phone? I have a SM-G900A, but it does not have EU languages.

Any difficulties that will occur doing this? Or can I just download the stock SM-G900F ROM and flash it safely?

Difficulties? Joking? It's rather a tricky process as G900A has a locked bootloader and you want a ROM from another model.
You definitely cannot just flash "F" firmware with Odin.
Schematically, this process looks like:
1. Go to G900A section and find COMBINATION ROM there.
2. Find the latest G900A stock ROM and make a firmware Odin-flashable tar from it (bootloader, kernel, modem, recovery).
3. Find a G900F ROM you want to be on, prepare it for flashing if needed.
4. Flash Combination ROM, gain root, install Safestrap recovery.
5. Flash G900F ROM from Safestrap recovery.
6. Flash G900A firmware package with Odin.
7. Enjoy.
Hello,
Is there a way to dowgrade the bootloader of SM-G950F with stock fw G950FXXUCDUD1 to further flash a stock fw Android 8?
- flashing a downgraded bl with twrp?
- with "combination" fw?
- with a modified stock bl flashed with Odin?
...?
Thank you!
No. Samsung will not allow flashing of lower bootloader versions numbers.
Hello, thank you for your answer.
Even with a combination fw or directly flashing an older bootloader with twrp?
No.
Combination roms follow stock firmware regarding bootloader version ( can't downgrade). TWRP is a recovery image to replace stock, You can do more things in twrp over stock except downgrade stock firmware.

Ok, but what about this thread which seems to say it's doable with combination roms?
(Method) For everyone who wants to Downgrade Galaxy S8 to Oreo/Nougat
Hey guys! I recently read many Questions About downgrading the Galaxy S8 to 7.0/8.0 after we got the 5x Bootloader. Well many of you say NO but What many of you forgot is that there is a way to Downgrade your phone. I already had that Problem...
forum.xda-developers.com
I've seen many guides on how to downgrade stock firmware. Most of them revolve around editing stock firmware. None of them mention whether the bootloader version was actually downgraded. To me personally you are essentially trying to install a custom type rom using by using stock firmware.

I checked and you're right. The minimal configuration for flashing the bl is a tar with cm.bin and sboot.bin and this leads to the usual error "... check fail(cm) device : x binary : y" (whatever odin version used... patched or stock)
reverse engineering sboot and cm.bin and changing the binary release doesn't help because the code is signed and verified by the PBL from the ROM.
The only way to do it should be to connect to the exynos jtag / uart / ? and to reverse engineering the soc (!) modifying the way the PBL check the SBOOT.
Adam Outler a researcher did it on GalaxyS (1 or 2!) more than ten year ago... (https://forum.xda-developers.com/t/how-to-hack-hardware-binary-and-bend-it-to-your-will.1338073/)
So... I think is doable with a lot of talent and patience...
Anyway, thank you for your help!
