Question I need help downgrading - Samsung Galaxy A53 5G

I want to downgrade from one ui 5.1 to one ui 4.1, has anyone done this? How do i do it? I got twrp installe.

Use Odin to flash the older firmware. Keep in mind that the bootloader may have an anti-rollback to prevent this.

Then you won't be able to flash older firmware unless you flash a custom ROM zip in TWRP.

Hi
Well is a good question , Chainfire said:
http://forum.xda-developers.com/general/paid-software/flashfire-t3075433
FlashFire is the most advanced on-device firmware flasher available for rooted Android devices. It can flash full firmware packages from various manufacturers, as well as apply over-the-air (OTA) and ZIP updates - all while maintaining root, and without using a custom recovery.
So in theory you can, but he also said:

Unlocked bootloader
While an unlocked bootloader is not strictly necessary for many of FlashFire's functionalities, we strongly recommend all root users to run unlocked if possible. With locked bootloaders, there is a much higher chance of a device being unrecoverable if something goes wrong. This is not just true for FlashFire, but for many root apps. The specifics are device dependent.
nevertheless , here in this thread they seem to have used and work

There's a difference between lock and relock.
Relock will say 're-locked' in the bootloader, and that's probably voiding warranty.
You can get it to say 'locked' by flashing official firmware, you have a few options here...
1. Firmware Finder
2. Flash update guide
3. Dload method (only for C636B136 and AL00C00B115)
4. FunkyHuawei (paid)
5. Dc unlocked (i think anyway, and paid)

No. When you flash stock firmware everything is back to stock. If there was a way to flash a modified update.zip with Twrp as recovery instead of stock recovery it would be possible. But as far as I know we can't yet. I've tried to repack using Huawei Update extractor but it doesn't want to, header mismatch. (this is on all extracted files, not just twrp)
The only reason to get locked bootloader would be if you needed to return the phone because of a software error. If it's hardware it should be replaced anyway.

Yep. Flashing stock firmware will do that.
You won't get rid of emui though. We don't have AOSP so emui is always there...

sorry for my bad thing. But can i ask you help me this case:
i have Mate 9 Pro LON-L29C636C361 (lastest Oreo ) , but my bootloader is unlocked, and maybe not have stock recovery .
So, which method can flash again full rom C361 (3 file : update.zip, data full, hw...etc) and complete back to stock with locked bootloader???
I read somewhere about method LON-HWOTA, but it fail when flash TWRP step, because i am on Oero, so this method can not use in this my case . Can you show me another way ?
to relock bootloader on Android 8 (MUI8), only works if you have your CORRECT oeminfo.bin. make sure you backup yours before rebranding
1. just flash TWRP
2. make folder folder HWOTA8 on SD card
3. Download HWOTA8 and copy "hwota8_rebrand" to SDcard
4. Copy your oeminfo.bin file to HWOTA8 folder.. Make sure to rename your file to oeminfo.bin
5. Boot into TWRP and install from SDcard hwota8_rebrand
Done bootloader relocked

Good.
What version Android was your phone on before the problem?
Were you on stock (factory) or on custom ROM?
Surely you weren't on Kitkat for almost 3 years?

When you downgrade back to lower stock, you have to omit gpt.bin command. Because you have a newer bootloader.
This is also why you can't take OTA. Because it tries to install a different bootloader (which is probably still older than what you had with custom ROM). If you wanted stock 5.0.2 again, you have to flash full stock image and omit the gpt.bin command.
Are you able to use volume and power button to the bootloader screen?

Before this trouble, were you ever on stock Marshmallow 6.0.1? If so, you can flash back to full firmware of that, but needs to be the very latest. I'll find a link for you.
Also, do you have TWRP installed and did you have a backup you can restore?

OK, then that's the bootloader you were on and will always be on. You need to reflash that latest version (with the security update) to repair. Just reflash the entire full firmware.
There's a link to it here in this forum. I'll find it when I get home, if you don't have it.
Then in the future, if you try to downgrade, you always have to flash full stock version EXCEPT you omit the gpt.bin file. Whether 4.4.4 Kitkat or 5.0.2 Lollipop.
And you can never take OTA.
Because you really have 6.0.1 bootloader.

This is the most likely because all the methods say so old and not one was and when I try to pass any old stock also will not always get that error in the bootloader in the gptbin downgrade logs

You can not flash any older gpt.bin files. You have to omit (leave out) that flash command.
Your gpt.bin file is 6.0.1, and you cannot downgrade. Even on 4.4.4, trying to accept the 5.0.2 OTA update is still older gpt.bin file in that OTA than your 6.0.1.

Question About the Beta P Program on Verizon

So I have a few questions about the android P beta program. I was wondering if anyone could answer before I opt into it
1) if I opt into I get ota updates which won't be Verizon variants so would I be able to jump back to Oreo?
2)would this allow me to unlock my bootloader possibly?
1) You should be able to go back to oreo by opting out of the beta and taking the subsequent ota from Google. Or you can manually flash a newer ota you downloaded from your computer. Must be a newer build than the the one you are on.
2) Almost certainly not. Unless there is some error, your bootloader will not be unlockable. You are not currently receiving "Verizon" builds. No such thing. Your device info is on a server side whitelist / blacklist. It has nothing to do with the build you have installed. That is my understanding.

If you unlocked the bootloader already, it will stay unlocked until you lock it via fastboot from your computer. Flashing firmware will not relock it. Don't worry, updating to Android p won't mess with that.
I'm really enjoying this beta so far. The new navigation gestures are cool. Nothing so far that makes me want to go back to 8.1.

That's correct. Just checking. You need to boot to twrp to flash magisk. There isn't another way that I know of. Maybe download twrp img again? I doubt its a corrupt download since you get the twrp splash screen, but its worth a try.

You can boot into the OS right? Are you're platform tools the latest version?
Reverting back to oreo, rooting, and updating to p beta will either fail or wipe out root. You won't end up with p beta and root. Don't do that.

It is very difficult to downgrade the bootloader and methods which worked in the past have been patched. If you don't know what you're doing leave it alone.
And to answer your question no, you can't just flash an old bl in TWRP and expect a rom to just "work". Your better off installing a custom rom with the version of android you want. Then you don't have to mess about with bootloaders.
