Need help with firmware!! - Samsung Galaxy S8+ Questions & Answers

today I got S8+ (g955f) a vodaphone variant.
Everything is fine except the vodaphone logo during turning phone on and off keeps bothering me .
Currently I am on pie (no root) .
So what I need to know is I can flash any g955f firmware if boatloader version of that firmware is equal to or greater than mine ?? And will there be any issues if I flash other g955f firmware in order to get rid of vodaphone logo and bloatware ??
Any help will b appreciated

Flash the latest unbranded firmware for your region.
All S8/S8+ firmwares are on BL v4 now, so bootloader version won't be a problem in this case. Make sure to do a full wipe and factory reset after flashing.

[Q] How to change CSC to branded 920F

Hi, first flashed french 5.1.1 and now that vodafone has released the branded 5.1.1 want to back to stock (ATL) but when flash the sammobile package the csc changes to SIM (vodafone slovenia) and there´s no way to change the csc.
I´ve reading a lot and seems the ATL package is multicsc and flashing defaults to SIM. and there´s no possibility to change csc because cant root 5.1.1
Im totally stuck. Why want the branded? the operator customization and VoLTE activation.
Thanks to all
Do a factory reset in the bootloader, boot up and then flash the operator rom again
*#272*IMEI#
Tried flashing, boot, wipeall twice, flashing wipe data and cache but the multicsc stays as SIM csc...
*#272.... doesnt work in this devices.
tried to downgrade to 5.0.2 and root to change manually csc but the bootloader is upgraded keeping downgrades.
the only hope is pingpongroot or anyone can root 5.1.1 without tripping knox
Bring your S6 back to Samsung for official ROM flashing back to stock.
Only way to change CSC is to root...

Yes it is True. Please read the 1st post. OT described his problem as flashing the French 5.1.1 from his previous 5.0.2 ROM. When the 5.1.1 version of his country came and he flashed back using the ROM from Sammobile his CSC was changed. I encountered this same problem. My S6 is unrooted. Only way to change CSC on unrooted device is to root. I tried the methods above and did not work also.

Did you let the phone boot completely after flashing the new firmware and then do the wipe from recovery?
Yes I did. My unit is G920FD from Philippines. Downloaded 5.1.1 Globe Philippines (CSC:GLB) from Sammobile. After successful flash via odin with Full wipe at recovery the CSC defaulted to THL (Thailand). I tried all Phillipine-based 5.1.1 ROMs from Sammobile and flashed them all (3) with full wipe at recovery each time but sadly still CSC is still THL (Thailand).

You could try without a simcard (flash, boot up, wipe in recovery) or a different simcard. I never manage to change csc either in 1 go and the results can be different, eg sometimes I get Vodafone apps installed and sometimes not....
Will try it without a SIM card. Thanks.

Did this work in the end? I've got exactly the same issue except my CSC is stuck on SIM (Slovakia) when I want it to be UK

I also tried it but couldn't get it to the correct CSC (VDF in my case) either, I can do it with other packages and get it to PHN (dutch)

I have had managed the csc change also with odin, fw flashing. BUt it took at least 10 flashing, but did it.
please note, that I have had issues after ANY of XEF firmware flasing. After XEF fw, I was very difficult to do this odin flashing method succesfully. BUT it did.
but I cannot rememe what was the sequence of this procedure. I was using 5-6 different ZIPs from sammobile.

do you have ANY idea how you did it? Are you actually sure you changed the CSC without rooting the device on a firmware that was multi CSC?

i have flashed the XEF. and that was wrong. esspecially it broke the spo2, and stress measuring... I would go back to another, BUT after XEF, I always had flashing interrupt in the HIDDEN file stage.
But after I have found a flashable FW again ( maybe SER or SEB) I was able to flash XEH, or BTU. and it was changing the XEF to SEB OR SER after wipe in recovery.
The only rom I will never flash againt is XEF.
ps: i never root this 920F

Now I was able to reproduce it twice!!! :
How it works : on devices where dialer NOT shown up CSC changer (e.g.: GS6920F) :
Go to recovery, Dial up, Home + Power
wipe cache and perform a factory reset
next is important : power down the phone. NOT to reboot.
Power on in download mode: volume down+home+power buttons
FLASH for example : BTU :
G920FXXU3COI9_G920FBTU3COJ1_G920FXXU3COI9_HOME.tar
after reboot, it will be English, and If U go to recovery it will apply BTU.
Hope it helps
p.s.: It wont works with EVERY Firmware. don't know WHY. For example :
I wanted to flash after succesfully changed the CSC from TPH to BTU, so I wanted to flash XEH....BUT that resets to TPH after XEH flash.
So at least to BTU it works specially if you are in TPH CSC !

Your Odin error is due to flashing older firmware version ( Bootloader)
The firmware you mentioned above is the latest version 3 bootloader so you should be able to flash that.
Latest version firmware is G955FXXU4CRI5 (September with bootloader ver 4) if you want to update to the latest firmware.
Flashing the firmware will replace your recovery.
You can use this to find the latest firmware for your phone

N971N - Korean Firmware to Uk Firmware

I was hoping someone could help me out. I have a Korean firmware Galaxy Note 10, i have scoured through the internet trying to find a solution or a flashable firmware to change it back to the UK firmware, to my recollection they both have the same processor.
I have gone as far as rooting so that it could open some doors in terms of reverting back to the UK firmware. i was wondering if anyone could help.
Everytime i tried flashing the UK firmware using Odin it would say the bootloader is locked, however i did unlock the bootloader before attempting to flash the firmware.
Maybe the UK firmware you trynna install is older than the one you already have? Maybe it's preventing flash for such Security reasons?
Tried flashing bootloader only?
Firmware without bootloader?

would you know where i would be able to obtain the firmware?
You can't install Uk firmware onto n976n, this model has only 4 CSC available and all of them Korean.

Question Get back to stock ATT firmware from U1 unbranded firmware

Hello everyone! Today I unbranded my s22 ultra by flashing using patched odin, latest firmware for SM-S908U1, to use it in Italy with Vodafone carrier.
Everything went fine except that for some reason, 5G is not working nor 4G+.
I tried then to get back to stock ATT firmware but failed in every attempt. What I tried is:
- Flashing ATT firmware with Patched odin
-Flashing ATT firmware with patched odin 3.14.4
- Flashing ATT firmware with normal odin
-Flashing ATT firmware with normal odin then perform a factory reset after the setup
I always flashed the full package, CSC, Userdata included.
Every time that the system booted up I ended up with standard unbranded firmware. No, ATT customization and obviously no 5G.
Can anyone tell me how to get back to stock ATT firmware ? I totally ran out of ideas...
Usually going between U and U1 requires a factory reset

The thing is, the phone was always factory resetted as I flashed CSC and useradata every time. Still I tried to flash ATT firmware with normal official odin, then skip setup and factory resetting. Didn't work.
Maybe I should try doing it with patched odin?
Did you try the AT&T U firmware or the U1 firmware with an AT&T CSC? As far as I know, you'd have to flash any U firmware for your model, such as T-Mobile, then upon inserting the AT&T SIM it will revert to AT&T firmware. Yes, cross flashing requires patched ODIN.
The U1 firmware is unbranded and will not fully activate on AT&T or Verizon UNLESS the SIM card is already activated provisioned for 5G. Do NOT use U1 if getting to AT&T stock firmware is your goal.
