Question Can we downgrade from one ui 4.1 to 3.1 on a52s 5g ? - Samsung Galaxy A52s 5G

Can we revert back from oneui 4.1 to 3.1 on a52s 5g using odin safely without any issue ?

Yes

I confirm this is possible as I did it at least twice when I was creating my rooting guide.
But I still don't understand why you want to do this as you will remain with a very old security patch and as One UI 4.1 is very good....

plsss tell us how i have sm-a515f on one ui 4.1 and wanna go back to one ui 2.. download mode give error of unsupported rom and unofficial type of thing\

See: https://samfw.com/blog/what-is-bit-binary-value
The value of the new rom has to be the same or higher than the current one, else flashing will fail.

Arobase40 said:
In fact, there is a misunderstanding in your explanation or partial explanation as if the bit value is higher than the current one then this is an upgrade and not a downgrade...

Yeah I know, figured its a small topic anyways, doesnt hurt to know the general principle..

I was able to downgrade from Android 12 to Android 11 with no trouble. I used the non home csc. First thing though make sure your boot loader is locked for the initial installation of 11 just be safe.

very simple. download the latest android 11 firmware. use odin and load the ap bl and cp files, and also load the NONhome csc (you'll have to start from scratch). go to download mode on phone and run odin.

Is it possible to do that? I'm in the same boat.

Yes it's possible but we need to flash on top our (tmobile) kernel.
I also can't find our tmobile frimeware tar (for odin in case of bootloop)
Damn....booooooring
Hmm I'm downloading the TMO firmware from SamsungUpdate to start, but it's gonna take another 6 hours because of their metered connection -_-.
We'll see how that works out, but ideally I'd be 100% debloated and rooted with Samsung Pay working.
Don't think that'll be possible, but at least we're dealing with unlocked bootloader devices haha

My edge plus is already on 5.1.1 - why the desire to download the same version of firmware from another country? Maybe I'm missing something...
That's not new
Guys, the phone is running great!
Updating for the sake of updating isn't always a good thing when out of the box it's actually working well!
When a device has problems there are threads everywhere of complaints. When a device works things are quiet usually with just the usual how to question. Of course everyone wants root, when it comes it comes. Be patient!

I do not believe you have to do anything.
While yes, both are version 5.1.1, if you look at the last 4 digits of your firmware build number you should see AOGD. The new firmware build number ends in AOH2, showing this is a newer build date. Nothing major, probably just a few under the hood changes, which usually means a liitle better performance.

what about the root-ability?
If you are rooted on an older firmware, and you flash a stock rom via Odin you will lose your root access. So long as your phone model can be/is rooted on your current firmware, after you flash the newer firmware just follow the same steps to root your phone again.

Sorry but what are you on about? Android 7.0 hasn't even been released for this device yet....
This is all well and good but as stated by Alex Android 7 isn't out for S6 edge + yet. And I'm pretty sure when it does come out it will change the boot loader and reverting back to 6.0.1 will cause imei and baseband loss.

I was on Nougat multiple times (Khongloi S7 port ROM and DevBase 7.0 ROM modifications), returning to MM was as easy as going to TWRP and flashing a MM ROM, without any bootloader business involved... In my case I simply flashed the V15 Note 7 port by Khongloi, and I was back on MM without any bugs or problems. And if you didn't notice, the firmware in this guide includes a bootloader, so even in the case of the bootloader changing with Nougat, there would be no issue reverting back. I've downgraded my Note 4 from Marshmallow to Kitkat multiple times (for testing purposes), and it's as easy as doing the same steps that are provided in this guide
Go down to the development section, you can see that there are multiple Nougat ROMs that exist for this device already, all based on a leaked base ROM that was meant for app developers. The ROM is nowhere near to finished, it drains battery and the performance is poor, and for that reason many users will consider downgrading, and this thread works for that purpose

No, the performance and battery life ratio really is worse in the ROM, it doesn't benchmark even close to stock MM and battery drains fast on some occasions

This might be due to the fact that they are ports of 7.0.
Im just warning people that update to official when it comes out that it has been known that it updates files that once done cannot be reverted back or it will cause problems, one being the null baseband/imei.
But yes, reverting back at the moment is as easy as flashing a 6.0.1 rom or stock firmware.
Either way hopefully people back up their efs!
i updated to an official 7.0 firmware and now i can't flash 6.0.1 bootloader. Any ideas or am i stuck at 7.0?

Well hopefully people will back up their EFS which is a MUST do before starting to flash roms etc.
If you have I think you can use odin to go back to 6.0.1 and then restore the backed up EFS from that version of Android.
Other than that you're stuck on nougat roms.
If you have reverted back to older and you lose imei and/or baseband then you'll need to reinstall nougat rom to get the imei/baseband back.
But as I haven't flashed an official nougat rom I can't say if this will all work or not. I'm going by past experience when I did this with jellybean - kitkat on my old phone.

Greetings @roberto_1986,
Your choice between A9 and A10 will summarize easily. Do you need one of the new features provided on A10 which was not present on A9 version? If you do not know or if you are not sure, then you dont need A10, stick to A9 for now. Less bugs, better performance and battery life. OS is more mature.
Now regarding rooting, on A9 Rom nothing as easy as pressing the root button under the LR TWRP (1104 version for A9 1210 for A10), then pressing the Closing AVB 2.0 button and you are done. From there you can update to latest stable version within the OS (do not use the beta ones, no point using those and it did not work for me). Works like a charm. I am on MIUI 11.0.2.0 (A9) EEA and never had any kind of issues using this method a few times. I never tried the A10 version of the LR TWRP so I have no idea if they offer the same option for rooting on A10 or not.
You can also unroot from that same LR TWRP in case that would be required at some point.
Hope this helps.

I am unsure if OFFICIAL TWRP 3.4.0 is meant for A10, I suggest you to read their its thread to see if people are using it on A10 or not. Personally I installed it yesterday on A9 and it saved my day restoring a backup made with some other UNOFFICIAL TWRP.
The UNOFFICIAL LR TWRP (chinese/english) which was released last year is the version which includes the rooting ability for A9 (and maybe for A10 too). OFFICIAL TWRP does not have such additional goodies since it is the OFFICIAL branch of TWRP.
You can check this guide using the UNOFFICIAL LR TWRP to root device, ALL steps you need to take to root your device properly are explained here. That's for A9, not A10.
[GUIDE][BEGONIA]Unlock Bootloader, Flash TWRP and Root[PROPER]
Note a quick search within forums would have probably leaded you there, try it next time, that's helpful feature of forums
As for the UNOFFICIAL LR TWRP (by wzsx150) thread for P and Q you can find it there:
[RECOVERY][begonia][UNOFFICIAL by wzsx150][P/Q]TWRP recovery for Redmi Note 8 Pro
Rooting A9 from the LR TWRP 1104 is guaranteed to work. That's what I used myself. As for A10 (Q) I have no idea, check/ask the thread.
Let us know how it turns out and you did to make it work.
Good Luck!

That's very wise not to install stuff you find from internet from unknown sources.
Not sure how you found that website, but I never heard of it or even seen it for the matter. I would not consider it safe myself.
I used to be able to download stuff from MiFirm which *looked* more legit but who knows.
You can find the required files from the xda threads I posted above, it may come from individuals, but I do consider it safer somehow because we have feedback from xda users. Back then when we installed those unofficial version there were not official support of any kind anyway so we kind of had to be 'advanturous'. I dont even remember from where I got mine myself.
Best I can do for you is to provide you with the checksums of the file I did use to root my A9 and reflashed not so long ago.
Code:
$ md5sum recovery-TWRP-3.3.1-1104-REDMI_NOTE8PRO-CN-wzsx150.img
e41bba28984f14ea56da98448cd2c17d *recovery-TWRP-3.3.1-1104-REDMI_NOTE8PRO-CN-wzsx150.img
$ sha256sum recovery-TWRP-3.3.1-1104-REDMI_NOTE8PRO-CN-wzsx150.img
8f203aec69f1ed021badac0f94d1906fcf0530f0e41beddcbc49652705c8731b *recovery-TWRP-3.3.1-1104-REDMI_NOTE8PRO-CN-wzsx150.img
This way whatever source you are getting the file from you'll be able to check it against my sums which will guarantee you got the same version I did use. However I cannot guarantee they are 'legit'.
Before you proceed any further, I want to stress you never told me the flavor of the phone you own. Mine is Global EU phone flavor running an original stock MIUI.11.0.2.0_A9_PGGEUXM. If own a Chinese flavor (ordered on Alibaba, Aliexpress etc etc) you need to be extra cautious for example as they tend to brick more from what I read.
I also remind you need an unlocked bootloader and I strongly recommend you to apply the Anti-Brick solution as described in my previous post. If you restored to stock image using MiFlash or SP Flash Tools it is very likely you need to reapply those even if you did it before. Best to apply them twice than none.
Hope this helps.

The Megathread is pretty much self explanatory for the Anti-Brick method, I cannot explain it any better than how it is explain there. Please refer to the link given in one of my previous posts and just apply the first part with flashing preloader.bin and lk.img as explained.
It will basically provide you with a safety belt in case you do anything wrong with your phone on A9 resulting in bricking the device, bootloop or whatever, so you can Flash stock back on using MiFlash / SP Flash Tool without having to need an authorized account.

This file might not be there, it is a file you have to delete to prevent OS to restore Mi Recovery 3 over your TWRP at reboot (making impossible to have TWRP stick on the phone).
In order to see that file you first need to mount 'system' in the options but as I said it is not always there.

A10 benefits is not worth the risks to me. The Anti-brick method is well explained in the Megathread I posted the link few posts earlier, however, it's for A9 only not A10.
Looking at the lists of bugs still present on A10, I really see no point running A10 atm. But well anyone does what pleases him/her he he
Good Luck!

The Megathread is pretty much self explanatory for the Anti-Brick method, I cannot explain it any better than how it is explain there. Please refer to the link given in one of my previous posts and just apply the first part with flashing preloader.bin and lk.img as explained.
It will basically provide you with a safety belt in case you do anything wrong with your phone on A9 resulting in bricking the device, bootloop or whatever, so you can Flash stock back on using MiFlash / SP Flash Tool without having to need an authorized account.
This file might not be there, it is a file you have to delete to prevent OS to restore Mi Recovery 3 over your TWRP at reboot (making impossible to have TWRP stick on the phone).
In order to see that file you first need to mount 'system' in the options but as I said it is not always there.
Glad I could help! Sharing the bits of knowledge we have here and here is the best thing in the world, bits of knowledge are only worth something if shared with someone else yeah!
Now that you are rooted dont mess up with your phone eh!

It used to pass before, at least it was when I first installed it. Then google made some updates and it is not passing anymore. I am not an expert about that, but I know there are some threads where people are talking about this particular thing.
What is it useful for?

I see.
No actually it was the other way around. When I first rooted in Feb it was passing both tests (green true).
Then one day after google made its changes it stopped working. But I only retro-graming so it is not so important for me.
Have you tried MagiskHide for the games you want to play with?
I cannot really help you with this further because I never tried to fix these myself not really needing to.
Anyway if you search Redmi Note 8 Pro forums you will see some other people are having the issue, at first I thought it was a A10 problem but probably is with the device.
Also you may found help in the telegram group REDMI NOTE 8 PRO OFFICIAL many gamers there I think.
Good luck and please let us know of your findings.

Can anyone help I want to flash SM-G988B older official rom to go back to UI 2.1

As title suggests I'm not happy at all with UI 2.5 which has destroyed my battery and SoT and lost some other features I really liked for my SM-G988B S20 Ultra Exynos model .
Can anyone help with the latest official f/w for UI 2.1 built number code to download it and flash it from Sammobile?
Thanks in advance for any help

You can't downgrade bootloader (bl). It's a mission impossible.
So I think that it won't work.
Please let me know if you are able to downgrade to one ui 2.1

That firmware is bootloader v4 and I don't think there is any v5 yet is there? So it should work fine

It is v4 and it worked just fine without triggering the knox.. Did a smart switch & samsung account backup before I downgrade at the version I mentioned (latest before UI 2.5 that is) and everything works just fine. I already feel the difference in battery life.. /sigh
Will probably stay here until UI 3.0 if I don't see any other important feature added. Only some camera features I'll miss but battery is the most important thing and I'm not willing to sacrifice an hour or two of SoT for UI 2.5
Thanks all for your help

Noob Question about note 10+ version

Hi everyone hope you're doing excellent I bought a note 10 plus on november last year suddenly I stopped receiving OTA updates this have at&t logos but its unlocked already I work at an airline and I'm not using at&t sim card since I bought the phone and even with my country's sim card I received ota updates.
I was wondering if its possible to flash it to android 10 currently the phone is running android 9 but when I connect it to the pc smart switch says phone is up to date, same happens when I verify software updates from the phone.
Baseband version: N975USQU1ASGO
My questions are:
- Can I flash the phone using any of the android 10 firmwares in the forum? or do I have to make sure it will be compatible with some specific versions?
- If I flash the phone it will it still be unlocked?
thank you.
Don't know.
I would leave it on Pie; stable, fast and well behaved.
Scope storage and the trouble it may cause hasn't been dragged out into the sunlight yet... plus the older apks it probably will break that have no replacement.
If you do load Q let us know what you think.

From the lines above we know it's not locked but caution because it isn't rooted neither.

Possible, yes ... if it's desirable only you can determine after acknowledging de pros and cons of the upgrade. As @blackhawk pointed out, there are some caveats to be considered. Nevertheless please be advised that this is your decision and none here can be responsible for mistakes or misfortunes that may occur. It's all on you.

If these are real issues, I would suggest tackling them with the upgrade and if not solved, even downgrade back.

Your baseband version if circa 2019-08-18 so ... pretty ancient for any device freak terms (like last century)

The above question has more than an answer:
a) The firmwares available in the forum are for rooted devices so the answer is NO. None firmware available here is fitted for you present setup (the "but" comes later)
b) Yep ... you have to keep compatibility of your hardware with the firmware you flash. Your devide is a N975U so you shall restrict only for the respective family.
And now comes the "but" ...
The firmwares in the below list shall fit your hardware. They are official Samsung releases for the hardware you've mentioned.
https://www.sammobile.com/samsung/galaxy-note-10-plus/firmware/SM-N975U/USC/
The above list was filtered only with USA (No carrier) options because, as you've said, it's unlocked.
The complete list is @ https://www.sammobile.com/samsung/galaxy-note-10-plus/firmware/#SM-N975U and it contains the carrier locked ones too.
You will have to search and read about "flashing with odin". To speed up the download use Samfirm after reading some howtos about it too ... https://samfirmtool.com/
