I downgraded my SM-R805F from 4.0.0.7 to 4.0.0.4 (R805FXXU1FSL3) to change CSC to BTU (for spay). I was able to add spay without any issues, but no OTA appears in wearable app.
I'd appriciate any suggestions to update back to v4.0.0.7 without CSc change
I've made it.
The necessary ROM to get BTU OTA updates is R805FXXU1ESE2. Use this guide to flash but you need to flash CP aswell.
So the process to get Samsung Pay:
Flash R805FXXU1ESE2 (AP, BL, CP, CSC)
Change CSC to BTU with sdb method
Update OTA

hi, when i bought my n920a it had firmware 6.0.1 but with cs XSG of the arab emirates but now i can not flash this csc anymore. How should I do? also when I downloaded samsung flow did not make me use fingerprints because it said that I had done the root previously but I had already bought it so. Is there a way to root?
Are you sure your device was originally an N920A? And have you ever flashed the stock AT&T Firmware to your device yourself manually?
I ask it like that because, if you went and bought a Rooted N920A from an older firmware and then flashed a newer stock firmware to the device, you definitely removed the carrier unlocked modem and reinstalled the AT&T CSC. The firmware does try to prevent all other firmwares from being used.
You may end up needing to flash the modem from the combination firmware in order to regain your carrier unlock status, that may allow you to flash another region's CSC. But you would want to use a Home CSC version if you can. One that doesn't include the PIT file with it. The Home CSC version typically does not contain a PIT file but has a meta data folder that accompanies the cache image. The Home CSC also doesn't require a device wipe.
But if you accidentally locked your unlocked phone, I hope you didn't flash an unrootable bootloader over a rooted bootloader. But using the Combination Firmware's Modem/CP should allow you to change carriers and manually adjust APN or Cellular Settings. Although it may mess up your wifi defaults until you mess with wpasupplicant.
Thanks, I installed the latest firmware available NRD90M. N920AUCS6ERH1. Is it no longer possible to downgrade?
Hello,
So I am in France and it seems I won't get Android 10 update until March.
I have seen a lot of contradictory information regarding flashing firmware with different CSC, changing CSC...etc.
SO, is there a way to update to android 10 if I have the Multi CSC ROM, currently set to XEF?
Hi ondris,
You can use SamFirm tool, try to find it on xda, probably you're familiar with it. I've updated my phone, bought originally in Sweden, and I'm using it in Serbia with SEE CSC, you can use also BTU, phone will automatically detect network operator, and you are good to go. Flash it via Odin, steps are also on xda, and what I can tell you as an advice is that when you use Odin and flash CSC, you have CSC and Home CSC file. Regular CSC delete all the data from the phone, and Home CSC will save everything you installed and kept in you phone. I hope this helps you.
Thank you for the tips.
But the thing is i don't want the rom to change the csc by itslef.
I want to either change my crurent csc to one that has been updated to android 10 or flash an android 10 firmware with csc different of mine.
Can I flash SM-G960U US unlocked firmware on my SM-G960W device to get android 10?
Can you let me know if with my current CSC settings should I receive OTAs?
Originally I was at TCE/TCE,TCE/TCE
Then downloaded the MXO firmware and flashed it, once reboot i've got a french message then click ok and the phone took the MXO CSC.
But not sure why the XEF is in there, Samsung pay and members are working correctly.
Note that i flashed ATCT firmware thru odin today.
You install G988BOXM1ATCT CSC which don't have TCE CSC. If you want TCE CSC you should install G988BOWA1ATCT.
XEF is referred to your 2nd sim slot you don't have any sim over there because of that it is set to default CSC which is XEF(French CSC). You will receive OTA. I think you don't have to worry about anything. if you are still worried I would suggest you should Flash G988BOWA1ATCT Firmware with TCE instead of MXO firmware.

What if my SM-G988B is the single sim version? And there is no sim2 tray to put on my sim?

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.
Also created a thread: https://forum.xda-developers.com/t/csc-change-through-samkey-no-otas.4454801/
Despite fold3 and flip3 being listed as supported both tools fails to change CSC. So don't waste your money.
Only way to change CSC currently is via ODIN, and you have to flash a non-Common CSC, ie. if you keep flashing the OMC_OXM your CSC will stay the same.
