Use the firmware for your region, e.g. country of issue and figure out the region code e.g. XFA, XFE, etc.
Ok so I had the same problem as you. When you get this error in download mode, it's because you can't downgrade your bootloader.
The version of TW you're trying to flash has an older bootloader than the bootloader you have already install.
You need to flash the latest version of TW. You can find it on Sammobile or with the soft Samfirm.

AT&T CRD6 OREO on 930U and CANT revert back to BRA1, BQE1, BRD1 in Odin

Literally no matter what I do. I cannot flash ANYTHING in Odin to either revert back to 7.0 or stock 8.0. Its not flashing any version of 7 or 8 and its not flashing any U firmware or AT&T firmware.
What am I doing wrong. I flashed 8.0 with the intent to be able to revert back to stock s7 once official Oreo rolled out and I literally cant do anything in Odin. I've tried odin 3.13 and 3.12 prince version. HALP
update: flashed G930UUEU4BRD1 using odin 3.12 successfully. phew

ur csc is bad, had the exact same thing a year ago,
just install twrp again
flash csc pack (if there are csc packs for snapdragon variant), flash any csc u want , i did it twice just to be sure
and after that go flash stock firmaware with same csc code
so if you install btu csc then flash the btu firmware with odin afterwards,
dont flash the home_csc .tar in odin just choose the normal csc thats in ur firmware folder
hopefully this works for you too mate

damn, well i dont know what you can do then maybe try combi frimware, should have root acces add see if you can flash that way?
dunno just trying to help
Factory resets and try to flash the rom again I don't think it's a baseband issue like exy.
Make sure what needs to be clicked in Odin from the instructions are clicked too
Still having problems

Question Get back to stock ATT firmware from U1 unbranded firmware

Hello everyone! Today I unbranded my s22 ultra by flashing using patched odin, latest firmware for SM-S908U1, to use it in Italy with Vodafone carrier.
Everything went fine except that for some reason, 5G is not working nor 4G+.
I tried then to get back to stock ATT firmware but failed in every attempt. What I tried is:
- Flashing ATT firmware with Patched odin
-Flashing ATT firmware with patched odin 3.14.4
- Flashing ATT firmware with normal odin
-Flashing ATT firmware with normal odin then perform a factory reset after the setup
I always flashed the full package, CSC, Userdata included.
Every time that the system booted up I ended up with standard unbranded firmware. No, ATT customization and obviously no 5G.
Can anyone tell me how to get back to stock ATT firmware ? I totally ran out of ideas...
Usually going between U and U1 requires a factory reset

The thing is, the phone was always factory resetted as I flashed CSC and useradata every time. Still I tried to flash ATT firmware with normal official odin, then skip setup and factory resetting. Didn't work.
Maybe I should try doing it with patched odin?
Did you try the AT&T U firmware or the U1 firmware with an AT&T CSC? As far as I know, you'd have to flash any U firmware for your model, such as T-Mobile, then upon inserting the AT&T SIM it will revert to AT&T firmware. Yes, cross flashing requires patched ODIN.
The U1 firmware is unbranded and will not fully activate on AT&T or Verizon UNLESS the SIM card is already activated provisioned for 5G. Do NOT use U1 if getting to AT&T stock firmware is your goal.

Question Help returning to stock ATT firmware for S22 Ultra

I have an ATT branded S22 Ultra (SM-S908U) where I flashed unlocked firmware using Odin (was trying to sign up for 5.0 beta...but even flashing unlocked firmware does not show me sign up option in Samsung Users).
I am now trying to return to stock ATT firmware, however, Odin fails at file analysis for both AVA6 and AVC8 firmware.
Is there anything I'm doing wrong?
Factory wipe. Make sure you are using patch Odin. If it fails and boots to emergency warning screen do not try to get back to stock recovery. Just flash firmware again without factory wipe. I usually have to flash in Odin twice.

If you were on Beta (thats Rev 2) and you're trying to flash back to firmwares on (Rev 1) .....that's why your failing. You can't go back but to AVDC. And no matter what patched Odin you try.....nothing will get you to those firmwares.
*EDIT* I misread your post. But either way those firmware are not able to be flashed. You can only flash firmware within your REV.
