Unfortunately, you're on v3 bootloader and cannot go back to Android 9 as that is on v2 and older.

Is it possible to perform this downgrade if I unlocked the bootloader/rooted the device?

If you have a G973U like the OP, then a million posts would let you know it's not rootable.
Can it be downgraded from 11 to 10?
only if your on the same bootloader version "whitch I think is V4"
its likely your phone is on a later version

Since this thread comes up in searches, I thought it would be good to add that as of now, the Snapdragon 973U can be rooted. The bootloader can be unlocked if it is version 4 or less. There are threads on XDA that tell how.

I am also looking for this option to try Resurrection Remix ROM. Anyone knows what is the last version of bootloader for Android 10?

For the beyond1qlte (Galaxy S10 SM-G973U Qualcomm) the latest bootloader version is 6 afaik.
To check your bootloader version look at 5th character from the right of your Android build number.
Examples:
bootloader version 5: N970USQS5EUA1
bootloader version 6: N970USQU6FUB7
Neither of those can be unlocked. As I said above, you need to be on 4 or earlier to unlock the bootloader on this device. @afaneh92 can give you more info.
EDIT: Oh, sorry. I misread your question. I don't know the last BL version for 10.

According to https://www.sammobile.com/samsung/galaxy-s10/firmware/#SM-G973U latest USA Android 10 firmware had bootloader 4 (per the check MtnX2 mentioned). You can look at other countries if you are not in the USA.
On Snapdragon phones, you cannot downgrade the bootloader, so if you're already on Android 11 or a newer bootloader, you're stuck there and cannot go to an older version.

I recently purchased (from ebay) a Galaxy S10 with Android 11 and bootloader version 4, and I was able to unlock the bootloader and install a custom ROM. It wasn't easy to find the device because now most S10s are updated.
Image attached showing Android 11 and BL v4.

I have an Exynos from Europe, already at Android 11 with bit v14... the latest one. I have found some older bootloader, but flashing with Odin was refused, with TWRP flasing process was successful, but it did not change the bit... so I guess I stuck with Android 11.

I believe Exynos can still be downgraded. The process is different for Exynos vs Snapdragon, so you may want to look into it more deeply... you just have to find Exynos-specific threads for the matter.

Its not exynos thread, but will answer you.
You can flash firmware has same bootloader rev, I assume 14=E
So only firmware with E on 5th character from the right on build number.

Update got May 1st update on att sm-g960u
The files are no longer available. Can you repost them.
I cannot for the life of me figure out whats going wrong. I bought SM-G960UZKAXAA (US unlocked s9). I wanted VZW's advanced calling features so I put SM-G960U on the device (instead of the SM-G960UI, as it should be). I've used the special Odin and stock firmware to revert, and it seems to be successful, according to Odin, but nothing ever changes. Still get the VZW splash screen and other VZW stuff. HELP!?

Your stuck on v2 bootloader as carrier bound devices released them first
Ypu will have to wait til u1 firmware releases a update to the v2 bootloader then everything should go back as normal
can you update the links?
also, how come one person said FED 1 2018 and another person said May 1st security patch?
if this is the same U1 firmware available in other posts, why flood xda dev with so much duplicate posts?

How do I unlock the bootloader of my Huawei mate 9 ?
Did you get the key before July 24? If not.... you can't. Not without paying some third party that might or might not work. (eg. Funky Huawei )
This worked for me. But you have to pay 4€.

It does work but first you need to downgrade your phone to nougat (Android 7.x) first and then it will work.

No, but there's a chance that the tools you buy access to might be able to extract that unlock code...no guarantee...no refunds...
EDIT seller says its 4.4.23+ EMUI/Android Version: 8.0 is that the unlockable one or is there more to the version that says it?

You need the build number and security patch date.
Pretty much all EMUI 8 builds on the Mate 9 run a 4.4.23+ kernel, even up through the latest security patches.
Once you know the build number, find it in Firmware Finder, and find the build for that region that enables GPU Turbo. If it's an older build, then it's likely that you could use the official rollback firmware to get the bootloader unlocked.

Yup, .375 is the latest one that's good, after that .377 had GPU Turbo and issues with downgrading.
so im good to downgrade? i will message you when i get the phone in a few days thanks

You won't get into the trouble that others did with .377 or later, yes.
But there's no guarantee everything works nicely.
Do read as much as possible before doing anything.
Also keep in mind that Android 9 is coming soon so maybe you don't need to unlock and whatnot.

I have N950UZKAXAA (USA Unlocked, carrier free) but about 8 months ago, i flashed the carrier version of Oreo with the hope that it supports AT&T wifi calling, but it was still blocklisted, so i moved on to Sprint. It gets monthly security patches up until February 1 (currently on N950USQS5CSA1).
I want to flash back the carrier free firmware, as i think it got Android Pie. Is it possible to flash Android Pie or Oreo again? If so, what version is good to flash?
Thanks
I think I can follow this below firmware ?
https://forum.xda-developers.com/galaxy-note-8/how-to/guide-sm-n950u-u1-t3685884
Oreo
N950U1UEU3CRC1
with "Odin3_v3.13.1_3B_PatcheD" ??
The guide says : Note - If you are flashing Unlocked Firmware from Carrier Firmware you must use Prince Comsy Odin otherwise, use regular Odin.
But no prince comsy for Oreo !!!

The Z builds are all bets builds. If you're still on a beta build of Pie, you'll need to flash to an official release. I sold my Note 8, so I'm not sure what the current build number is.
Hi,
Have heard of reports of people getting Android 10 via crossflashing to the Korean unlocked rom, but heard of possible caveats. Are there special steps to take? Besides loss of possible LTE USA bands in the firmware, anything dangerous about crossflashing to this
V409NO30b_00_OPEN_KR_OP_0515
firmware?
Thanks so much
Hello,
I have the same question. I'm tired of waiting Sprint for Android 10. Does it work with this Korean rom ? There is any step to be careful ? Thank you !
EDIT : if there is a Verizon Rom that work with Android 10, please let me know were to download it, i don't find it on lg-firmwares.com
Hello Phantafun/fireblade20, i have the sprint model. And i download the V405UA20A Verizon firmware from lg fan club and as soon as i booted the phone it requested me to update to Android 10, note i do not have a Verizon sim. I did not like the bloatware so i went for the Korean version V409NUA30d BEST DECISION EVER, nothing wrong, did not loose the network bands, plus the Korean version gets monthly updates.
Thanks a lot for the feedback ! I try it if as soon as I can get rid of the error 0x6004 CrossDl :/

sure ... because the korean version is 128 gb, memory, rom?
So, can anyone confirm that v405ua can be crossflashed with korean firmware?
I cannot flash the Korean rom (a new error code), but I finally get rid of the error code 0x6004 : i change the LGUP_Common.dll for another one found on another topic.
I'm on Verizon rom, it's really great : I can now desactivate the bloatware unlike the sprint Roms that lock this option.
I'm not clear on this. Is there a an android 10 ROM I can safely flash on a Sprint version?
