you need to flash unbranded, make a full boot and then do a factory reset in recovery

TWRP and Custom ROM on SM-G920i

I've found a couple of ROM's and the root method did work but I am unable to get a custom recovery for the model I have and I don't want to be stuck with a brick.
Model: SM-G920i and attached is a screen shot. I'm just hesitant to try anything because it's a generic S6 not tied to any of the major carriers so flashing back could be difficult as I don't have the custom ROM.
Anyone?

You can also use flashify from playstore for custom recovery, or pingpong root for rooting.
Flashing custom recovery will void your warranty.
What firmware are you on? I have the 920i, and I had problems flashing twrp until I upgraded my firmware with kies and odin.

What I did was flash it via kies and it went back a stock non carrier branded version and then twrp took and now I'm enjoying my custom ROM.

[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...

Not true. I did it several times on unrooted stock devices.

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 !

Dreaded MDM does not allow factory reset!!!

Wanted to start a new thread on this subject, as I know that there is plenty on it within this site. I have perhaps unique problem with this however. I have a T810 stuck in bootloop and can not get to any UI. I can access recovery and boot loader, but USB debugging is not enabled. I am fairly versed in recovering devices, so I am open to any suggestions.
Where to begin? Suggestions?
Day 2 of this project:
I started with 6.0.1 stock ROM flash as I could not complete a data factory wipe. Stuck in bootloop...
Downgraded to stock 5.1.1... new boot up, but still looping only this time it is cutting off and on.
Then tried changing ROM CSC version from XAR (US) to XAC (Canada) b/c I thought that I had a Canadian version... still looping
I was able to install TWRP 3.1.0 however, thought not sure what I can do with this from here.
Maybe try custom ROM and root from TWRP?

UPDATE: TWRP factory data wipe cleared the issue!!!
Hello everyone, I was given a Samsung Galaxy A5 SM-A500FU, and I have the same problem,
I can not do the hard reset because of the MDM does not allow factoryReset. The phone will restart automatically.
I can not update via Odin because of the MDM.
How do I remove or exceed MDM to reset and update the firmware?
Thank you.

ur csc is bad, had the exact same thing a year ago,
just install twrp again
flash csc pack (if there are csc packs for snapdragon variant), flash any csc u want , i did it twice just to be sure
and after that go flash stock firmaware with same csc code
so if you install btu csc then flash the btu firmware with odin afterwards,
dont flash the home_csc .tar in odin just choose the normal csc thats in ur firmware folder
hopefully this works for you too mate

damn, well i dont know what you can do then maybe try combi frimware, should have root acces add see if you can flash that way?
dunno just trying to help
Factory resets and try to flash the rom again I don't think it's a baseband issue like exy.
Make sure what needs to be clicked in Odin from the instructions are clicked too
Still having problems

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.
