Hi to all

You can try downloading a Nougat firmware and flash with odin but use instead the HOME CSC of the latest Marshmallow TPH ROM an do NOT tick re-partition. A backup before is advised.

[Q] downgrade stock firmware

it is possible to downgrade the firmware from MGA (CSC I9505ITVBMH1) in MDF (CSC I9505ITVAMD8) with odin?
If you simply reflash your desired firmware using odin...I think it won't be an issue....but sometimes the phone gets stuck on the bootloop....then you need to boot to recovery mode and wipe data and cache...then everything will be ok...as long as you flash the correct firmware for the correct phone you'll be fine

Look here for the Odin flashable CSC file http://forum.xda-developers.com/showthread.php?t=2250824, or first select ITV with CSC Changer from Play (need root).

[Q] CSC Change and Stock Rom Installation

Hello xda! I want to ask you guys if it is safe to change CSC via CSC change app and after that if i can update my samsung galaxy with stock rom without causing me problems. I have XEF CSC, i have changed it to EUR, my android is 4.3 rooted with CF Auto Root and i want to install EUR 4.4 firmware. sorry for my english! :angel:
1. Use Triangle Away for reset your flasher counter to OFFICIAL.
2. Make a backup data folders of ur Internal Card (you will restore it when u will flash android 4.4.2).
3. Make a factory reset.
4. Take a look if ur CSC still EUR. If not, change it again.
5. You are ready sure for install android 4.4.2 via OTA, ODIN or KIES 3.
6. Enjoy it :highfive:

Help me understand CSC codes, Flashing different firmwares and Odin

OK - I started with a unbranded UK A300FU - CSC code BTU on 5.x
I flashed a (supposedly) UK VOdafone 6.0.1 rom using Odin and the ROM n the AP sjlot
It appears this failed - my Modem wasn't updated an WiFi failed - the advice elsewhere is to go into download from a cold phone.
Also, it would appear the firmware wasn't UK, but some germanic version
I restored from a TWRP backup
My phone details now says the "orginal CSC Code" is VD2
If I want get back to showing Original code as BT should I re-flash in Odin the firmware that matched the twrp backup ? If so , should I stil use the AP slot, or should I use the CSC slot?
Many thanks
Use CSC slot.
Also, the reason why your TWRP backup restoration didn't touch the CSC is that it has it's own partition, which one normally does not backup.
You could flash an entirely unbranded marshmallow rom of your choice, and flash the BTU CSC of lollipop, it should still theoretically work.

AQL5- fails to update system error 7 - re-partition

Hello.
To get oreo I flashed AQL5 firmware via odin with re-partition unchecked.
I choosed normal CSC file not HOME_CSC in odin.
After flasing then in recovery factory reseting my CSC did not change to DTM ( AQL5 fw was with DTM csc ). Previously and now I still got PLS CSC.
Also after first configuration. Had to make a wierd license authorization via knox from my network provider.
NOW WHEN I want to update to oreo via stock recovery getting E:error in /sideload/package/zip status 7.
