I had to change my CSC code from VAU to TEL while on combination firmware then flash TEl firmware
Today I changed CSC (Galaxy Note 10 Plus) from DTM to DBT using Samkey. After that I flashed Firmware DBT via Odin.But I am afraid that I will not receive OTA updates in the future. I'm not sure Samkey really changed the CSC! But after i pressed Change CSC my phone restarted and then it was written in the program "succeeded"
When I looked in System Info it was still written DTM but I expected this because I have to install Firmware DBT for it to change. After I changed the CSC using Samkey (I hope it has really changed) I flashes the last Firmware DBT > Android 11.
I'm concerned now if I will receive OTA updates in the future or whether I have to install them manually using odin
Can someone pls help me?
Did you receive OTA's after CSC change through Samkey? I have the same doubt in my S22.

I have a SM-G985F/DS that was originally CSC as TPA. I got a 5g sim but it wasn't showing 5G ( i didn't know that the s20+ doesn't even support 5G). Anyways, i figured if i change it to Tmobile CSC that it will be work. TMB wasn't availiable on the CSC so i just picked TMS(slovakia tmobile). it worked but my connection is worse than before and i cant change it back. I used *#272*IEMI# to access the preconfig before but now it won't work (same day, same softwar, same everything). It keeps saying "connection issue or invalid MMI code". I also notice that as it runs the USSD code, the signal drops from 4G to H and then fails as soon as it changes to H. And it is consistent, meaning the USSD is causing that switch in networks or something. I have tried to reflash stock firmware from TPA, MAX, XID but the CSC from the firmware files are not changing the phone's CSC. The software build does reflect with ODIN being successfull and everything but the CSC just wont change. I also hoped that even if the CSC doesn't change with the flashes that the *#272* code works again; however, not the case, it still doesn't work.
I had read that android 10 allows for google phone to access the menu directly but i can't downgrade either. I keep getting bootloader check and kernel check errors on the phone side. I even tried to downgrade in the same order as upgrades. Even the latest previous build didnt work cuz it was binary 6 instead of 7.
Does anyone know how to fix this? Need help to either fix the CSC or how to downgrade to android 10 without issues(bootloader version and kernel version issues).
*samkey does not support my device.
PROBLEM SOLVED (SORT OF): I installed another multi CSC firmware that did not contain TMS and it was able to switch to the default on that firmware. When i switch back to OXM multiCSC firmware it defaulted to French CSC but *#272* code still did not work. But it worked on the other multi CSCfirmware. So looks like i won't be getting TPA back which was getting LTE+ receptions just fine. I switched over to OWA multicsc firmware which contained TCE CSC which is in mexico and uses the tmobile network for roaming. But it still does not use LTE but shows 4.5G which i assume is the same as either 4G+ or LTE. Either way, speed test shows ~40mbps down which is a hell of a lot better than ~5mbps on TMS.
i changed CSC on my G986B using samkey so they support s20 for sure.
Hello everyone, a few days ago I flashed the new firmware for samsung S20 Ultra manually because updating was not possible from the settings on the phone. I got a "registration failed" error. After flashing, when I insert the SIM card and try to call, I get the error "not registered on network". The phone country id is WWC but i can`t find firmware with that csc code. I flasched telenor Serbia MSR code. Any help or information is welcome.

Idk if is still helpful, but try to install ARO (Argentina) firmware, it will get you a firmware that will receive updates. It also works for S21/S21+/S21 Ultra.

Both of the imei are shown and are clean. What can i do? The rom version is A720FXXS9CTJ2 brazil
Forgot to add that my carrier operator stuck to greek cosmote. My new sim is vodafone. When i insert the sim. I get the welcome to vodafone message. My contacts are there but not network registered. Sim info shows the operator as cosmote and not as vodafone
Hi! Did you solved it?
Make sure your imei from phone box and phone be match!
flashing new rom changes 'efs partition', which have your imei registration infos!
Useful to reflashing firmware from sammobile with re-partitioning option on (by pit file) !
If not works follow this: ref-a-2017-modems-and-bootloaders-collection.
