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.

Samsung S7 edge stuck on Galaxy s7 edge logo after FW flash

My Samsung Galaxy s7 edge G935FD is stuck on the "powered by android" logo after I flashed a firmware for a different country on it through Odin.
I am unable to access the Download mode or Recovery. Can someone please help me?
Thank you
Edit: I was able to enter the download mode but do not know what to do now.
You can enter recovery mode too. You have to wipe data and clear cache... Otherwise it wont boot up

Thanks for replying mate. I wasn't able to enter "Recovery Mode" but I could get into the "Download Mode" and I flashed the Firmware again.
Turned out the problem was that I only flashed the AP file and not the BL, CP, and CSC files. Earlier we only needed to flash one file (that's why I got confused) but in newer models since S6 we have to flash all these files as well.
CSC cointains the pit file so it will auto repartition, and wipe your data.. (and internal memory) so if you just need to reflash the system but remain the data, don't include csc and will work, but only if the firmware is the same as the one you already have.. (for example for unroot) and remain your data... remember if CSC is attached to odin.. your phone will be fully wiped

I was changing Firmware on my device to another country's, so had to flash the CSC.

Home CSC for SM-A510F?!

Hi Guys,
I've got a Galaxy A5 2016 (SM-A510F DBT) from a friend. The device seems stuck at the last system update and does not start anymore. Since he did not backup his data, I try to flash the latest firmware via Odin. I read that there is now a 4-part firmware version for Galaxy devices and two CSC files. The Home CSC file supposedly does not reset the data when they flash, but I can only find the regular CSC files. The firmware was loaded with SamFirm.
Someone an idea?
Thanks!

Galaxy J5 PIT image

I need help with the PIT image of a SM-J510FN. I accidentally wiped Stock, and can't flash Stock firmware cause of hidden.img. (It's carrier is form Vodafone, CSC is CNX). I tried to many things to do it (extracting, editing firmware CSC's etc) but i can't.

Galaxy S7Edge G935F UK

I have a Samsung S7edge G935 that had boot problems and I have been trying to flash with the standard firmware from Sammobile and also Frija. I could not get either firmware’s to flash with Odin in windows as I kept getting Pit loading errors etc etc. As many know Odin for windows takes forever to report an error so in frustration I wiped the nand thinking that I could reinstall a nandroid backup off an identical phone I have. Clearly I was wrong. I have found on this forum the FWUL application which I have working and although I have not yet succeeded in flashing the firmware it does at least give the error messages in an instant. The firmware’s from Sammobile and Frija are correct for the phone UK BTU and I have unzipped the CSC files to obtain the PIT file which I must assume is the correct one for the rest of the firmware. I still get the same error in jodin ‘ pit file corrupted would you like us to get the correct file for you’ but there is no obvious way to accept the ‘offer’.
