Backup Firmware before root? - Samsung Galaxy S8 Questions and Answers

Hi Guys
Hopefully, someone could point me in the right direction.
I'm ready to Root my S8 phone, but previously lessons with Samsung have Taught me I'm going to need to backup the firmware before I do anything.
Has anyone managed to do this before?
I know there is stock firmware out there to download when I want to revert. But last time on my S6 I lost the ability to use google play music because of something with firmware issues.
Maybe this was to do with having brought my phone in New Zealand.
I tried many different firmware and roms until I realized there must have been something not compatible with my phone and I gave up.
I haven't found any guides yet as I google this topic.
Thanks in advance guys!

[Q] Please help me with rooting & flashing

Hello there!
I have a Galaxy Note 3 i9005. I used to have it rooted (towelroot) but I accidentally updated the phone to version 4.4.2 which sadly removed my root. I've had my phone for about a year, and I feel it's time to spice things up with a new rom, but I find myself lost in this whole flashing jungle.
So, my questions are, is it possible for me to safely root & flash my phone? If so, could anyone point me in the right direction? I've tried searching a bunch but it's very hard to find in-depth guides explaining the process in detail. I don't even know if such a guide exists for the Note 3.
I live in Sweden so I don't think the phone has a locked bootloader if that affects anything.
Please help me.

I've rooted several new note 3 with this method..http://forum.xda-developers.com/galaxy-note-3/general/root-root-xxufnf4-stock-firmware-knox-t2840150
I managed to root it with that method! Knox is 0x0, thanks for the pointer man
Now, I'd like to know how to flash a custom rom. I've been looking a lot at different custom roms, however I can't seem to decide which one I want. Besides, I don't even know if I'm able to flash my phone since I'm running Android 4.4.2. All guides takes for granted that you have some knowledge with flashing, which I don't.

I have a*samsung*galaxy*s5 G900F with android lolipop official state.
until yesterday i was really happy, but then i accidently deleted one of my albums with pictures and videos of my holidays.
So as you can guess i want to get those deleted pictures and videos back.
The first few hours i was searching for methods to recover them, i found a programm that wanted to root my phone and recover de lost data but every time i tried it failed.

so right now i need help with rooting my phone or towelrooting (dont know which is best for me).
i was looking trough the forums and there are too many pages too dig trough and alot of the how-to's dont have any working links anymore.

You can find all the info you need in this post.
Don't know what your firmware is but the oldest base you can go is NB1 (4.4.2).
Root the phone with towel root.
Install either flash fire or safestrap and flash the desire lollipop rom.
Hello! I don't want to start a new thread just yet, but I'm also stuck in a bootloop after a mishap during a manual update. Is it possible to recover any of the internal files when recovering the phone, or is it impossible? Honestly, I just want the files off of my phone more than anything else. There are a lot of memories there that I would love to save...I know, I know, I should have backed up those files, but that chance is gone now. :crying:

Updated to nougat beta. Would like to go back to stock. best method for doing this?

Hey everyone, I've seen several threads related to Odin and going back to stock samsung rom. I have an idea of the method but I was hoping someone with more knowledge than me could point me to a thread with the best and easiest method for doing this? Thank you in advance for your help
I de registered, then downloaded Samsung Smart switch on my PC. Then hook up your phone, and open the app, it should say there is an update. The update will be MM, and will downgrade ya. Be aware, it will wipe ur phone, so do any backups ya need to do.
Hope this helps.

Unrooting to stock rom?

Hi,
I have been rooting my note 4 since it came out and familiar with any problems that may occur with kernels and stuff...
I decided to sell my phone and put it towards an S8 when i t comes out, i am sending my phone to Mazuma Mobile but wanted to unroot it first but the stock firmwares i am flashing though Odin are stuck on the Samsung start up screen.
I am not sure about unrooting and need some help, the latest firmware i have tried is "BTU-N910FXXU1BOC5-20150423120804" - i have the N910F model but it wont load beyond the Samsung bootup screen.
Anybody give me some help please and maybe point me to the correct firmware that i should be using?
Appreciate any help.
Thank you.
Think i need to use the latest firmware - N910FXXS1DQC3
Can someone point me to somewhere i can download this please?
Every link i check asks me to buy an upgrade account to down load this firmware.
Cheers
