Just to do nothing wrong:
1. downgrade to pre august patch (any csc , e.g. XTC-N986BXXU1ATGI)
2. following the procedure, change csc to dbt
3. flash an original DBT firmware ending up with having DBT "forever"?
Thanks!

Edit: Okay, couldn't wait.
I have an eSIM activated, but this was not a problem.
After CSC Changer procedure i have got DBT/DBT,DBT/EUX/DBT.
Now i'll flash the latest september firmware from samfirm.
One thing was weird: CSC Changer showed that my phone was rooted... but it isn't...
Thank you very much! Worked like a charm!

Unable To Debrand Three UK Note20 Ultra

Hey guys. I have a Three UK Note20 Ultra and I'm trying to debrand the device using a BTU firmware version, but it doesn't seem to work. The ugly Three bootscreen and their apps still install onto my device. How do I bypass this? Any help would be much appreciated.

What is the version number of the firmware you tried to flash? What is the version number that's now reported in your settings?

Mate nothing is wrong with the firmware you flashed. You need to change CSC. Change your csc to BTU firstly.

OTA updates after changing CSC

Hello,
Hope you all are doing well.
A while ago, I have decided to flash the Russian firmware to get android 11 (Couldn't wait lol). Few days later, I have flashed the UAE XSG firmware. My device's original CSC is MID Iraq. Now, my current CSC code is as follows:
XSG/MID, MID/MID
Based on this, will I have any problems receiving OTA updates in the future? Someone told my the that the first two CSCs must be the same do that, but I'm not sure if this is true because the second CSC only indicates the type of sim card I have in SIM-1.
Here is a picture for more information:

Thanks in advance!

Hie
I also recently upgraded to Android 11. The problem is that now the device gives me the message "Emergency calls only" and won't connect to any mobile network. I am based in South Africa. I updated with the stock firmware CSC "CFA" for Panama (original) then also tried XFA for South Africa but still I get the same message.
If anyone knows how to solve this please help!!

How To Guide Samsung Wallet in Italy with European IMEI, & CSC

Hi XDA,
I come to you in great need.
So, i bought a European S22 Ultra on Amazon, but Samsung Wallet doesn't seems to work (pic 1). Of course i reinstalled the app, did factory reset, checked Knox count (which is 0 (0x0000)), and yet it keeps giving me the connection error.
I came to the conclusion that I have to change the CSC, but on Samkey my model (SM-S908B/DS) isn't listed among the supported models, but even if it was, won't it trip Knox?
Can someone give some advice about this problem?
Thank you!
Paolo
