Update firmware without lose any data - Samsung Galaxy S8 & S8+ Cross Device Development

hello guys!
I have a SM-G950FD (ZTO) rooted by magisk and TWRP recovery.
I need to perform updates by flash a zip or donwload via odin.
The problem is: when I try to update a firmware downloaded on Sammobile (tar.md5) via Odin it changes my recovery causing to lose all data.
This happen because on firmware that I donwload on Sammobile have a stock recovey included. Otherwise, if I use HOME_CSC will also cause lose data because of change on recovery.
I try a lot of things like, remove recovery file from the tar.md5, also try use Abyssal Kitchen, but I can't have sucess.
I ask for help plz! I just need upgrade my firmware without lose data by flash a update.zip or donwload a .tar via Odin using a firmware that I donwload from Sammobile.
Kind regards!

[Q] How can i flash a ROM if I formatted my S2?

Just flashed the cf-root kernel
Went into recovery...
Formatted phone, accidentally didnt click update.zip
I then rebooted my phone... and of course i cant boot into anything because i formatted the internal storage.
Can i access USB storage? and then my custom recovery?!?!?
(I can only access download mode!)
OR
Any way to flash a ROM onto my phone via ODIN or other software???
Im stressing out as i cannot get into recovery (only download mode) HELP!
I'm sorry, but I can't understand your question.
If you're able to enter in download mode then you have no problems. Run odin and flash any firmware as *.tar or *.tar.md5 file(s). And... What do you mean that you've formatted the phone? through recovery you can do: factory reset or format some partitions - nothing else. So if you have a CWM backup on sdcard you just have to flash any stock firmware via Odin. then you flash CF-Root kernel, then enter in CWM recovery and restore your backup. No worries
p.s. my salutation to Ozzie. I was over there many times

I have wiped all my data via the recovery, the phone wont boot.
i can get into recovery and download now.
i try to install CM7 via my recovery and i even tried to restore my stock backup it keeps saying .md5 fail operation aborted (or something), can you link me to a .tar file and how to use it?
Im guessing i just click PDA then select the .TAR file then click start when my phone is in download mode?
KF3 kernel too :/
Im so lost.
Ok, look at this thread: http://forum.xda-developers.com/showthread.php?t=1075278
You have to download any firmware you like, then you flash with 3-files: PDA, PHONE and CSC. you don't use PIT file with re-partition. Then in this thread: http://forum.xda-developers.com/showthread.php?t=1103399 you can find CF-Root kernel for your firmware revision and flash it as *.tar (PDA). That's all.

How can i change csc in a custom rom..?

Hello guys!
I want to ask something.
I have just rooted my sgsII with a CF-Root 5.5
and i have installed through cwmr, a custom rom.
Everything is fine!
I have a question..
I want to change the csc that custom rom have (NEELP4)
with the OXXLPH (i have download the csc file).
So, can you tell me how?
Thanks in advance!
Using Odin.
Put the phone in download mode
Put the csc in csc and flash. Remember it might wipe the phone.
I tried that once, but then the phone stack at boot screen..
If this is the correct method, i will try again.
(i checked only the csc box at odin).
Any other suggestions before i give a 2nd chance with ODIN..?
Why dont you flash a custom ROM like mine.It has a muti CSC pack including the CSC for Greece because the Dev is greek.It would be a lot easier and less risky.Click on the link below that says ICS
Thanks for your advice.
I want to try for some days the rom i have now..
Any other suggestions?
Is the correct procedure to flash only the csc with ODIN?
Yeah mate just put it CSC dont select anything else and then hit the start button.Could wipe some data you have on your phone and some say that you should do a factory reset after the phone boots so if you have Titanium then backup your apps.

do i have to unroot in order to update in odin?

simple question
I'm rooted with 5.1.1 tmobile
I want 6.0.1, I got the firmware file ready to flash with odin, do I have to unroot first then flash or am I good to flash it ?
No, just put your phone into download mode and Odin flash like you usually do.
You will need to root after most likely I reckon.

Softbrick - how to find CSC

Hello guys
Unfortunalely i managed to soft brick my s9 Plus.
I changed the CSC when it was working but don't remember to what.
I can boot into download mode however when i try to reflash via odin it says Fail.
I am guessing its because of the incorrect CSC file i am using
Does anyone know how to find CSC of a softbricked phone.
Attached is the screenshot from download mode. Hope it helps.

If you flashed another CSC with Odin, you may have to do a fatory reset / wipe data in recovery mode.
That is why I always use the "Home_CSC" file as CSC in Odin - to prevent this wiping.
For stock firmware files, I am using Frija: https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910594/
