It sure worked, but... I am still on android 10... I was going to downgrade to android 8.
I got my firmware from SamMobile, but apparently it is binary 2? Where can I find the firmware for android 8? (Did not understand how to find android versions in androidfilehost)
Edit: I followed this tutorial on YouTube: "Downgrade Android 10 Roll Back To Android 9 On All Samsung Galaxy Phones S9+/S9/S10+/S10e/Note10" by Android Doctor
you can not downgrade to oreo officially now. you can flash lite rom oreo a custom rom by lite team.
I'm pretty sure Samsung prevents downgrading by blowing an e-fuse which prevents downgrading. I think they did this so that people cannot use special firmwares (without tripping knox) to remove FRP locks.Why can't one downgrade when you have the firmware? (I am a total noob when it comes to this side of android)

Has anyone figured out how to downgrade from 10 to 9 yet? I've tried a couple of tutorials, but they either not using and S10e but an older model WITHOUT Samsung bootloader locking, or they've been rooted - which I'd prefer to avoid.
I run into the error: "CHECK FAIL(BOOTLOADER) DEVICE: 7 BINARY: 3"
Then beneath this: "Pit_flash_binary - UNSUPPORTED VERSION".
Surely there MUST be a way to do this...?

That means you are trying to flash older binary into your phone which is already in newer binary (bootloader). Meaning that no, you can't flash older firmware into a newer one.
... Which means the e-fuse is something new since Android 8 or 9, as I've downgraded previously without this problem.
Would my only option now be to root, then or is there some way to downgrade the bootloader...?
I mean you can technically downgrade as long as the bootloader versions are the same.
Just as an example, if you are on Pie U3 bootloader, you can downgrade to Oreo U3 bootloader as well. You wouldn't be able to downgrade if you were already on Pie U4 bootloader and wanted to downgrande to Oreo U3 bootloader.
Well, it's the bootloader for this accursed Android 10, so I assume this will make downgrading impossible, dammit.
Ok. Next Q; can I assume the only way I can downgrade the bootloader is by rooting the phone...?
(It's just rebooted by the way. I don't *think* Knox has been tripped, as the version info is all there and nothing indicating otherwise.)
I'm not sure if there's a way to do it with or without root to be honest, I've never had the need to research anything regarding downgrading the bootloader. Hope you find what you're looking for.
