Question Downgrade with custom firmwares - Samsung Galaxy A53 5G

Hello hope you're having a good day, I'm looking for way to downgrade a53 5g from Android 13 to Android 12 ??? I found some firmwares for Android 12 but the binary number is 4 and Android 13 is actually on binary number 5 , no way to do the downgrade with Odin?
I read somewhere that is not possible to flash a firmware with different binary number is it true ??
I would like to comeback to android 12 it's better if someone has a solution it would be so helpful

Impossible to flash lower binary versions with Odin

you can try grab a a51 4g firmware, then extract system.img from it and then flash it with twrp as a system image (yes) (yes) (yes) (yes again)

[Resolved] #Solved# Any Possible Solution to Downgrade Back to Nougat?

Hello all
Been a member here for some time now and have a perplexing issue.
I upgraded a Samsung Device SM T395 to OS Pie 9 and decided I didn't like it. (There are no other posts with help on this matter)
I kept the STOCK roms Nougat 7.1 and Oreo 8 and want to put Nougat 7.1 back on my device , but is proving difficult using ODIN 13.3.1 or any other version of Odin. The result is FAIL, that's using a combination of AP, CSC, CP and BL.
I managed to get Oreo 8 back on it, but want Nougat 7.1 original installed instead.
Can anyone tell me can ADB Fastboot be used to Flash a Stock Rom back on a Samsung Device or is Odin the only method?
I know there are other similar programs like QFIL and Qualcomm that I have used for the Mi Max brand devices.
The device was rooted with Nougat 7.1 originally and I have USB debug set and FRP / OEM lock off also. So there's no problem there.
The last resort (stupidly expensive idea :crying is for me to buy another exact device that has Nougat 7 installed when boxed up!
I don't see how upgrading to Pie 9 and then wanting to go back to the original factory installed rom is a big problem, can anyone explain?
Would a CUSTOM Nougat 7.1 rom work if installed via TWRP ?
I have also come across this COMBINATION Software https://samsungcombinationfile.com/samsung-sm-t395 that is supposed to allow the downgrading of Android software, but hasn't worked as I had been lead to believe.

Samsung firmwares can not be downgraded. This is due to your bootloader version number. The bootloader version is the 5th number from the right of the firmware being downloaded. You can also check in setting - about phone - software info - baseband version ( 5th number from right). You can also tell bootloader number in download (Odin) mode with a line saying AP SWREV B:? : K? : S?. The B is your bootloader number.
Combination firmware works on the same principle in regards to bootloader numbers.
You can only flash the same or higher bootloaders version numbers.
Custom roms will work as long as the bootloader version number is the same ( or higher ) than what is on you phone.

RE: spawnlives. Many thanks for clearing that up, I now understand. Like many other people I have been trying to mix and match BL files from different OS variants to try and trick the device into accepting the main Nougat AP file via Odin, but nothing works.
These NEW combination files suggest that it is possible to downgrade the BOOTLOADER files on certain devices. However I downloaded all that was available for my device and tried the lot and found the only ROM that would flash correctly and properly was the latest one with the Binary 4 Bootloader. The rest would not register in Odin due to MD5 binary error messages.
In download mode my device AP SWREV B:4 K:2 S:2. ( So I have binary 4 which was released in January 2019, I believe). and this must have been updated when I updated to OS 9 Pie , using all the AP, CSC , BL and CP files.
So as you say, the answer is either , look for a Nougat 7.1 rom with a BL file that has a BINARY 4 code. Or buy another device that has the original Nougat 7.1 installed, which is silly really. :laugh:

The best you can do is roll back to Oreo. A new phone running nougat would be the best choice. I don't use custom roms but they all seem to keep up to the latest version. I have not seen one that ( latest version ) that is nougat favoured.

RE:spawnlives
Yes having researched the total list of softwares for the SM-T395 device, it seems the BL was updated to 4 on the 2nd roll out of Oreo 8.1. And having checked ALL stock Nougat variants, there was never any release of 7.1 with a bootloader binary 4!
I presume the BL Binary version is the 5 character from the right on the picture. (underlined red) :good:
It would make sense for Samsung to give the end user a choice what software they want, by keeping the BL version the same or giving a choice of BL selections to allow upgrade or downgrade.
Anyway, I rolled back to Oreo 8.1 with the binary 4 BL. And unfortunately there aren't many CUSTOM roms , nor a working TWRP for the Samsung Galaxy Active Tab2.
Thanks again :good:

Yes the bootloader is 5th from the right.
I don't own a tab2. If no work twrp can be found and you want to at least have root try using magisk and used the patch root method.
Also to avoid possible upgrade turn off automatic updates in setting - software update as well as in developer option - auto update system.

Have rooted the device no problem with magisk and patching the original boot img file. Then flashing patched boot img via odin. Causing device verification to need to reformat the device, resulting in correct root.
Once a device , this device is rooted, no official updates can be installed anyway. When you try to uodate software, a pop up shows as the device recognises the software has been modified.
As for TWRP there ISN'T any version of TWRP available for the Samsung Galaxy Active Tab2 (SM-T395). I have even emailed the makers , developers of TWRP why there isn't one in their device inventory list on their webpage.
So no TWRP, and NO custom roms either for this model.
My concern , was all about finding a valid , safe way to downgrade back to original Nougat 7.1. And until someone can produce a working image with a BL with binary 4. Then there's only one optiin and that is to buy another untampered device with Nougat 7.1 out of the box and leave it un updated. :good:

To answer your question of how is downgrading such a big problem, it is due to security reasons, to keep your device as secure as possible with the newest available software and the latest security updates.

sw rev. check fail(bootloader) device 8 binary 6

i cant flash stock rom (INS) pie version using oding 14.1, i did try using xtc firmware it says sw rev. check fail(bootloader) device 8 binary 6 too. how to fix this?? please help
Hello! sw rev. check fail(bootloader) device 8 binary 6 means that the ROM you have downloaded has a binary 6 while the device has a binary 8. In Android, or at least Samsung phones you cannot go to a lower binary than the one present in your device. Basically the only fix I believe is to download a ROM that has a binary of 8. If you do not know what binary it has I will leave a screenshot showing which number signifies a binary (Only mind the number in the binary, the U is a part of that but you just need to look at the number when you're downloading the correct ROM).
download latest stock
You have updated your device to Binary 8. Which means you have an updated bootloader. Samsung no longer allows the bootloader to be downgraded so you are stuck there. Anyways there's no worries. There are alot of ROMs and mods to use that you may enjoy.
Bootloop
Hi. Sorry for my bad English.
My problem is that despite uploading the rom, my phone is in a loop and uploading the rom does not help. Please help.

Hi. Thanks for the suggestion, but unfortunately after successfully uploading the latest software from my region (XEO) nothing changes. The phone is rebooting and it's still looped.

Firmware, CSC and Samsung

Hello, I wanted to ask a few questions
After a firmware flash with XPG CSC code for example is it possible to change the CSC code to THL and vice versa?
Is there really any way to lower firmware to a lower version?
If so, what file / path do I need to do this?
what is the differences between OXA and OXM?
Is there a place where you can read about the new changes that Samsung has made in recent years in terms of security that can not flash firmware to an older version and can not change CSC codes?
I know how to root a phone and use ADB (ADB in a very basic way)
Thanks!

Fail to flash with odin to downgrade from android 10

But since about the s8-s9 days Samsung implimented anti rollback , wich are not so clear , some phones cand downgrade to a previous version and some dont due the firmware setting the minimun version bar higher so to speak .

Question Downgrade A53 (A536B) from android 13 to 12

Hey guys all good?
I got my hands on an A53 already on Android 13 (U.I 5.1), then I unlocked the bootloader, rooted, magisk working but then I decided to downgrade from 13 to 12 because of a few things
I tried via Odin (13.14.4 and 13.12.7) and both didn't work the first odin it fails the flashing and the second pass but it didn't flash the whole thing just reset the phone
any idea? or I'm now stuck with Android 13?
Cheers
From what I can find, Odin supposedly won't allow a downgrade if the boot loader version is lower.
That's just what people seem to say about Samsung devices and downgrading. I've never tried it and never will. Would immediately use multiple OS versions however if Android actually supported dual booting. Its fantastically messed up that it doesn't.
Not sure if TWRP will. Didn't look that one up. You didn't bring that one up but it might be a way to do it.

Thanks for the reply. I was thinking something about that too. Not that the bootloader is lower but that it was modified (root) i guess
Unfortunately TWRP is not compatible yet with Android 13 UI 5.1 at least accordingly to this topic
So i guess I'm stuck for now
