Can downgrade? yes or no?

Hello is it possible to downgrade this new firmware release?
I have already tried all other stock ROMS and ODIN FAILED all time.
I just want to confirm if its possible to downgrade, if yes, then how to go back to 5 1 1.
Thank you for reading

I think it is better to prevent user to downgrade their Phones. As you know, since Android 5.1.1 released, Google replace the Samsung Reactivation Lock with their Factory Reset Protection. But in the lower versions of the android, there is many way to bypass this protection on Samsung Devices. Samsung fixed it on their security patches. Just imagine that if user can downgrade their phone to any version of android, when a thief steals the phone, they can easily to bypass it and make the phone become theirs.

Thank you for replying but I am still clueless if I can downgrade that specific android version I showed in screenshot above.

no one?

Have you tried TEKHD's stock-rooted 5.1.1?

You cannot downgrade... Once bootloader is upgraded there is no way back. You can try but highly you'll end with bricked device ... Also if you try custom roms they wont boot due to mismatch bootloader and recovery. Maybe if you search google you will find a way to do it but if i was you i would not take the risk

Can't install TWRP

Hey!
I am not being able to install TWRP since I returned to my Rom stock.
My device is xt1064 (bought in florida)
Does anyone know any solution?
Methods I tried:
1)by doing it via fastboot: This message appears when I do it

2)Via android: I tried to root my phone and later install it via the official application. unfortunately I don't know any application to root in marshmallow, so I installed stock android kit kat, I rooted my phone and later installed twrp on the application.
the problem was that I was unable to flash things, or basicly I wasn't able to do anything with it because everything failed.
I installed marshmallow again, because twrp failed after I deleted everything.
Does Anyone know a solution?
I apologize for my bad grammar. I am 15 years old and I am from Argentina.
Greetings.

I did it again on another pc and somehow worked.
I don't know why it worked, because I tried before on that one and didn't work.

<<<PLEASE>>> I need help. "Nand writer start" and does nothing else

<<<PLEASE>>> I need help. "Nand writer start" and does nothing else
Hello everyone, I have a problem, if you can help me, I want to put the rom stock of android 8 but when I put the 4 odin files it stays in "Nand writer start" and does nothing else. I have flashed many phones but never I had this problem. The mobile is not rooted or anything strange, it has the factory Android 9 ROM.
I have tried odin 3.09,3.10 and 3.10.7 and the problem persists.
What can happen?? :crying::crying:

I'm assuming you're trying to downgrade to a version with a lower bootloader version/number, which you can't do
You can only downgrade to the version with the same bootloader number.

So I can't downgrade to the android version 8?

did you tried with another tool?

Yes. I tried with odin 3.09,3.10 ,3.10.7, 3.13 and another ROMs the sammobile :crying:

The bootloader is locked in Pie after each OS update to prevent us from downgrading the OS on our devices.

Could this be the solution?

read up all about downgrading bootloaders( its not possible). check what your phone currently has then check what youre flashing. the 5th character (number) starting from the right when checking firmware build is the BL revision.
u can flash an equal or greater build. not a lower one.
also only 3.11.x and 3.13.x and future odin versions work on note 9 to flash firmware files.
in the picture u posted, your issue is the odin build.( ure using and old 3.09.x build)
while rooting might alow you to flash a custom rom(oem unlock is the 1 step to rooting) that is oreo based, not sure why one would want to do this. Q is just around the corner and keeping devices up to date now a days should be paramount.

Thank you very much.
I tried this to unlock the OEM and it forces you to format the smartphone completely, it doesn't work.

What firmware are you trying to downgrade from?
It would help if you could post more details to allow the community to figure out your problem and help you.
BTW, If your bootloader is higher than the firmware you're trying to downgrade to, then the process will fail. I'd start by double checking that.

First:
I flashed the latest Firmware available from SAMMOBILE.
this firmware
Now I want to downgrade to this firmware
Reason: some of my apps have incompatibility issues..
Thanks

What you are trying to do is not possible, as that would imply a downgrade of de bootloader.
Your firmware G998BXXU4BULF, cannot be replaced by G998BXXS3AUJ7.
Note the underlined/bold numbers above, which indicate bootloader version.
You cannot flash firmware with lower bootloader number, as already stated bij @enigmaamit.
Report your issues with apps to the app-makers, they should update their app to be compatible with Android 12.
