Downgrade firmware? - Samsung Galaxy S21 Questions

Hi guys, I have one odd question.
Is it possible to downgrade android and OneUI version to android 11 oneui 3.1?
I'm on the latest version od Android with August security patch.

Yes its possible. YOu have to use ODIN and correct firmware files.

but the aug patch put us at
G991USQS5CVHC
i thought with the '5' baseband, we couldnt go back, plus it wont boot into bootloader any longer even thou the option is still there in the recovery menu, just a full reboot.... id love to read up on where these steps are... from what i read, im hosed after being upgraded from 4 to 5? plz tell me im wrong, and there is light at the end of the tunnel... ID kill to go from U to U1

Problems updating stock 4.4.4 to 5.1

Hi there,
sorry for bothering you with my problem but I really cannot figure out what I am doing wrong. I am running a pure stock version of 4.4.4 on my international version of the moto E, with no root and no unlocked bootloader. I am willing to update to the latest 5.1 build but whitout unlocking the bootloader and stuff.
From what I understand the first step to do so in the easiest way possible would be to download the first 5.0.2 soak (22.21.32 341MB) update and put it into the main SD card. From then the phone should detect the update from the settings, but mine isn't.
I have already tried sideloading the update by going to the recovery and choosing update from adb. Also I have developer options enabled.
Thanks for your help.

Well, 1st of all let me tell you, that you are completely going the wrong way.... You DO NOT need to flash 5.0.2.... From what I know, factory images of XT1021 for official Android 5.1 lollipop are available...
Check this LINK
There are three versions, choose the appropriate one. Download it, and use mfastboot to flash the latest FW (Don't worry, because these are signed images and will work on devices with locked bootloader)
If u think that these are quite complicated, just hit the play store, make sure that Motorola Update Services app is updated.... and wait for the OTA.
If you are 100% sure that you have not unlocked the bootloader, then pm me, I will give the instructions to flash the fw.
Cheers

I am sorry, but I think I made a mistake
The official image is not available for your model at the moment. What u can try is wait for the update to be pushed.
Sorry for the inconvenience.

Hi good people of XDA, i'm currently running a samsung j500h with a 6.0.1 update.
I really want to root it. I tried every possible way and followed every instruction on every sites that i went through (including here). But it doesn't seem to work on my phone. So i asked a developer form facebook and he suggested that i try downgrading to lollipop, from there root my phone and install a pre rooted 6.0.1 rom. But i cant do that as well.
Here are the errors that i'm getting:
CF-autoroot,twrp and su update flash: phone cant boot into recovery, it shows the samsung logo but with a black line that ramdomly pops on any part of the screen and slowly making it blur.
Cf auto root on the other hand, makes my phone stuck on the logo. it never boots now matter how long i wait.
Downgrading:
Error on phone says like these: aboot write fail: Fused 2>binary 1 (something like that)
it still boots and still on 6.0.1.
Does someone here has the same problem?

Unfortunately, i couldn't find any fix/tips about this after a Google search.
I'm not sure, but I think that if Samsung release new 5.1.1 updates, maybe it will have a new bootloader too and maybe then we can downgrade from 6.0.1 to 5.1.1.

Samsung has indeed become a huge crap. Android is an open source but these dudes always tend to make it a closed source. Really upset with this but we have no choice. Whether u update manually or via kies it will be the same.
And thanks henkate for making this thread. This will be proved useful to many. :good:
I got reply from moderator regarding sticky thread and he told me that sticky thread is not necessary because there are too low discussions on our J5 forum (it's not so popular) and that when our J5 forum will be more "developed"/popular, we could have a sticky thread which would contain all those important threads.
So, this thread will not be on top of this section ( Guides, News & Discussions) when there will be new threads or new posts in other threads.
thank u so much big bro

Even If u cant downgrade Bootloader, you can always just repack the system boot and recovery from 5.1.1 and flash and TADA you are back on Lollipop

I dont know if its easy like that since other people with other Samsung phone couldnt solve this.
Another guy got same problem with downgrading:
http://forum.xda-developers.com/galaxy-j5/help/flashing-twrp-error-samsung-j500h-t3501187 (read at "Downgrading").
PS: Please dont quote the OP. Thank you!
I know that you have asked and been told no but we have got to keep this at the top of this thread.
This is so important for people to know.
What's are best option to keep this at the top ?

Agreed. Quite often Samsungs bootloaders are backwards compatible with previous firmware.
Boot.img and system.img should be all that is required to downgrade and possibly NON-HLOS.BIN if there are wifi issues.
Not only that there's a possibility the bootloader doesn't need to be flashed and the MM rom will boot with the lollipop bootloader.
However there are no guarantees either way.

It's not fake. The two users who reported has J500H. The latest firmware changelist of J500H is not same as J500FN one (also I don't see a firmware with "J" at FN). Maybe the new update didn't come on J500FN yet.
Whether you believe it or not, it's up to you. Keep updating if you want, but then don't complain here that you can't downgrade.
You've been warned about this.
Thread cleaned up of all Off Topic Posts.
Also bump again and again is really not needed. Please don't do that again.
Can we please stay on topic?

[Can I flash update firmware to a newer version in one go?]

What i mean is, my current phone is 5.1.1. Can I flash firmware it all the way up to 6.0.1? Or do i need to do it version by version?

If your device got a full firmware for 6.0.1 then flash it, nothing to worry about it.

The reason why it is failing is because you are on a high boot loader, you current on V3 while the U1 firmware that you was trying to flash is on V2.. You can only flash firmware that's on the same boot loader.
You would need to download G965U1UEU3ARG7 and flash it in order to be on the U1 firmware...

I don't believe the ARG7 for the U1 hasn't been released yet. I'm still on ARF4, I haven't gotten any updates for ARG7 yet.
But you can get the firmware using the link below when it becomes available. It's the same one I used.

To be honest it takes as long as it takes... Though for the U1 firmware it does appear to be the last one released after the carriers.
I would imagine that before they release a firmware that covers all the carriers they want to make sure it works for the individual carriers... But that's a theory/speculation I have.

First time I have ever heard of a Sprint Lease Lock.. Now I am curious over what that is, so off to google searching for it.
Think I found what your talking about... I am not sure if flashing the U1 firmware will work in this case given it's an S9+ and not an S8. Hopefully it does when the appropriate U1 firmware is released.
Depending on where you got the phones from maybe try doing a return and get a refund?

No biggie... Just for clarification (if it helps in the future) you can only flash files with the same bootloader version as what is currently installed. You can also flash bootloader versions that are higher then what is currently installed on the device.
What you can not do is flash bootloader versions lower then what is currently installed.
Finding the bootloader version is easy once you know how. Using the firmware version indicated:
G965USQU3ARG7
The bootloader version is the number before the last 4 characters of the firmware version... In this your looking for the number before ARG7... Since the number is 3 it means this firmware uses the version 3 bootloader.

Got it all flashed and back up and running... Just took a bit to restore everything and all my settings. Haven't seen anything amiss as of yet, sure I won't find out if there are any quirks until I let things settle for a day or two.
** Update 9/10 - So far so good, working like a charm. Even the wifi issue I had where it kept saying my internet might not be available (even though it was, and turning wifi off and back on would make it work) seems to be gone. Thanks for the link kevindevonwilliams

To carrier switch you would need to flash the U1 firmware, then insert the carrier of your choice [not Sprint] then set up device, after download the latest U firmware which is 3SARI4 and flash it.
Do not flash the USERDATA unless it is for the carrier you switching to

ok, first off... your alias is awesome!! the mental image is horrific, but thats what makes it awesome!! ok, done with that now, wont drag it any further lol
second, what firmware version does it show in the about phone section? its about a 10 or 12 character alphanumeric and it would help us advise correctly if we had it
S9+ (SM-G96U)

yep, thats what i needed. Well, kinda. The part i wanted was "G960FXXU1APFO".
If you want to update, here is the UK version of your firmware. I couldnt find what country your firmware originated in, but im sure its available at the link below as well

Thanks, was on SM last night.
wasn't sure which one, as this is G9601
(forgot 1 above) difference?
Odin, best route? also will this replace the
Chinese/Korean reset/recover language?
*Craziest thing, put sim in today, thinking
Maybe it'll update..nope still running 5.o says it's
Running 8.1 in about phone.... Marshmallow after
7 tap..You think it was a rebuild? But why 5.0
Hell ginger would have been better with flash.
Take care.
