S8 Active Downgrade - T-Mobile Samsung Galaxy S8 Questions & Answers

Hello,
If this is in the wrong area, please forgive me. I tried my best to make sure it is in the right area, and I'm not super familiar with this site (though I've read here from time to time!)
A long time ago, my S8 Active upgraded to Pie, and I downgraded because I didn't like it at all. Well, I hard-reset my phone last week and I forgot to disable the update feature, and I have Pie again. So I want to downgrade again. However, using the firmware from sammobile.com and the latest Oreo firmware, Odin3 gives me a generic "failed" error. I suspect it's a bootloader version issue, but I really don't know enough about this to know for sure. My current firmware is G892USQU7CTG2 (T-Mobile). Is that bootloader version 7? If so, I think I'm screwed because, as I understand, you can't downgrade to a firmware with an older bootloader version... is that correct? The newest version of Oreo is G892USQS5BSG4, which I think is bootloader 5. If my understanding is correct, then... is there any way to downgrade the bootloader on my phone? I really really don't want Pie.
Thanks for your time and (hopefully) good news!

Downgrade Options? SM-T710 Nougat

I have a tab s2 sm-t710 on nougat T710XXU2DQCL that was installed OTA and would like to know if i am able to downgrade to 6.0.1. The device is 100% stock and was wondering if ODIN would give me any grief about downgrading. The PDA number of the 6.0.1 file is T710XXU2CPK1 (Cellular South).
Thanks
On paper, I think you should be fine. :angel:
I'd also like to know this as battery life seemed much better on 6.0.1 for me.
i did downgrade my T 815 from 7.0m to 6.01 using odin. didnt face any difficulties. i did a complete wipe/format after i downgraded .
Can you not downgrade with TWRP as well?

I used Odin and firmware downloaded from sammobile and it worked flawlessly. I've performed downgrades on over 100 tablets so far and they have all worked good.
Downgrded my t713 long time ago and didn't have a single problem, you just need to download a compaitable firmware from sammobile!

You're safe to downgrade as long as it's allowed. Older builds will fail immediately so there is no harm to downgrade.
I've seen a few people asking about downgrading. Whats the reason behind this? Is N glitchy?

N does not work at all well with DJI drone remote controllers. I foolishly updated my brand new SM-T719Y 8" and Now I cannot connect to my drone at all. I have an pre 2016 Tab S2 on Android 6.01 and bingo works.
This size pad is the preferred size for drones and has enough grunt to provide stutter free vision. Cannot comment on anything else about N as this pad will only be used for my drone...

Hi Beut,
I have been trying yo downgrade my Tab S2 SM-T719Y LTE from Nougat to 6.01 and have correct downgrade and Odin. Every time I try to downgrade it fails straight away, so I was wondering what you ment by "as long as it is allowed" & "older builds" will fail immediately.
I need to get this happening as I cant fly my drone.
Cheers Yts...
I don't have your model so it cannot verify. However, other models I can downgrade to older builds close to the Nougat.
Like SM-T580 or SM-P580, both are Android 7, QF1 and QE4 respectively. I can downgrade them to PL4 or PL2, Android 6 but not the PG1.
Q: 17 or 2017
P: 16 or 2016.
The second letter is the month it's released.
You also need the right bootloader, different OS has different bootloader. Many just flash the AP file only without bootloader, it'll failed when downgrade.
Is it possible that you cannot downgrade Nougat to 6.01 as every time I try on my SM-T719Y Tab S2 LTE, it fails straight away. I have tried 3 different downloads and all failed, but Odin will let me overwrite my Nougat with a downloaded version of Nougat from the same web location as I got one of the 6.01 firmwares from.
Here are my fail messages.

Is it me or is it this model of the Tab S2 SM-T719Y????
When downgrade to MM you need the BL ( Bootloader ) goes with the AP . Boot loader of Nougat is not the same as MM , however bootloader of LTE version is locked
Sammy doesn't want you to downgrade.. nougat is planned obsolescence, I'd say.

Hey I've been trying to downgrade my T719Y for days now. Constantly failing and googling everything I can to find where I'm going wrong.
How would I know if I have the LTE version? And if I do and the bootloader is locked, does that mean I can't downgrade?
If I don't have the LTE version, you're saying I need the bootloader and AP to downgrade? Where can I find the bootloader?
I'll keep searching and trying but this is wearing me down. Any assistance would be greatly appreciated. My surveyors can't do a damn thing with our giant UAV until I fix this
LTE version is the one that has SIM, usually it's next to SD slot. Most LTE versions have locked bootloader, that's why you cannot downgrade firmware.
I just kept an older phone for apps available only for 6.0. Like scr recorder. Otherwise there are no reasons to downgrade

Downgrade from Pie back to Oreo because of the camera app

Hi,
I've wanted to try a One UI Pie rom, which I did, I like the new user interface, hate the new camera. I put my feedback on One UI as a PS at the end.
I believe one of the ROMs i tried required me to update bootloader to Pie. Is there a way to downgrade to Oreo, so i can install Oreo ROMS? I tried 2 ROMs and i get a boot loop on both.
Thanks,
Daniel
PS: One UI feedback: Used to be able to take either video or picture one click away, now it's 2. You used to be able to bind the Bixby button to Camera+Take picture with BxButtons, and volume keys to video. No longer possible with Pie. You don't know how important that is untill you went to the mountains, and you need some phisical buttons to use with your gloves. And most important, adding the Dual Shot mod is no longer possible, which was taking the same picture or video with both front and back cameras, which is again verry important for me.

We need to know what your current "Build Number" is on the phone. You also can't downgrade to other bootloaders that are lower then your current one, so if you're on bootloader 5 you need to use the Oreo bootloader 5 version firmware or it will not work.

That's not a normal Samsung firmware.. Where are you from? Was that phone rooted or something? Considering that you have a different rom on the phone it looks like it's bootloader unlocked.. I'm assuming you're not from the USA and that your phone is a N950F correct?

He is asking for the "N950FXXS5CSA2" firmware to see what bootloader you are on. (Bootloader # is the 5th spot from the right. This case the "5" from "5CSA2" IS THE BL. Version)
Usually it's in about phone/software/ baseband if not there it should say in download mode (look for B: # (# could be 1 to 5)) few lines down I think.
If your on bl. Version 5 you can be able to flash any N950FXXS5..... firmware but not lower like N950FXXU4......

Hi, yes the bootloader is unlocked, I have a custom ROM, and my device is Rooted.
Baseband version N950FXXU5DSB1. So N950F, bootloader 5 I guess from what @BluePhnx said. Is there a direct connection between Bootloader 5 and android PIE? Or can Oreo ROMs be compatible with this bootloader?
Thank you for helping me clarify!

The only connection the bootloader plays is when you go from pie to oreo.
For eg. Oreo is N950FXXS5CSA2
Pie is N950FXXS5DSB2
As long as the bootloader is the same "5" you can go back and forth between pie and oreo.
BUT once you go to a, for eg. let say August security patch for pie, firmware with N950FXXU"6"DSB4 (this has bootloader version 6) then you can NOT go back to oreo. Because the bootloader won't downgrade itself, it will only stay at version 6 or go higher to version 7 and so on.
So if you want to go back make sure the bootloader stays at version 5....

See what @BluePhnx said? That's what I was trying to explain but he explained it better.. If you want to know what bootloader version you're on you do this see N950FXXU5DSB1 what you do is start at the very END and count backwards 5 letters/numbers and you end up on the number 5 like N950FXXU((5))DSB1 that equals bootloader version 5 but if you see something like this N950FXXU((6))DSB1 then it's bootloader 6 and if you were to flash that one you can never go back to bootloader 5 again it only goes forward but @BluePhnx explained it much better!

What is your CSC?
Warning I haven't done this yet since I'm staying on pie. So do it on your own risk! I'm just saying what other people done.. Also I would've done it myself too.
Download the last oreo firmware for your CSC. (The one before Pie.)
Download Odin 3.13.1 or the latest version on computer.
Flash Oreo and home-CSC
But if it doesn't work or you get lots of force closures messages then do this steps.
WARNING!!!! this will erase all data off phone so backup FIRST!
Factory reset phone
Flash OREO with CSC file (NOT the home-CSC)
(What I've read people are saying to do the factory reset option for it to work. I haven't tried it myself since I'm staying in pie. That's why I included the first option.)

The problem is most custom ROMs don't actually tell you the firmware code or bootloader version. And I only saw 1 ROM that actually told me that it will update the bootloader to PIE (without specifying the actual version). Do you have any pointers on what should I look for when installing a custom ROM to prevent upgrading bootloader (besides when the ROM actually specifies the Bootloader version of firmware code?

The rom should say what firmware it is based on. Like N950FXXU5DBS2. If not you can ask.
Eg. N950FXXU5DBSA2 - the "5" in ....5DBSA2 is the bootloader version.
You'll can check for your bootloader version in download mode.
Here is a screenshot: (not mine just an eg.)
But you should be able to flash back to an oreo bootloader as long as the bootloader version is the same.
Cannot open PIE after OTA upgrade last Friday.
After upgrade with previous release and security patch of 1st of January I checked somewhere last week and there was n upgrade then.
Last Friday I did see a new OTA update from Samsung and installed it, upgrading to PIE.
After restart I get an error with the SIM card slot. I have a dual SIM version in Spain PHE.
I am unable to use phone now.
Everything original. Only did the dual SIM + memory card. Which has been working perfect for me with OREO.
Which version would I need?
Did the official PIE update change the bootloader version as well?
I just need the double SIM and the memory.
Any help would be greatly appreciated.

Is there a way to upgrade to Pie without chaning the Oreo bootloader so you can downgrade if you absolutely can't stand Pie?

No there isn't. That I know of.
Pie needs the pie bootloader.
I think the only way is to root your phone and have a dev port the pie firmware to work with the oreo bootloader. If possible!
But you "should" be able to flash the 1rst pie release firmware and then go back to the last oreo firmware with a factory reset. (Not certain though so. )

Trouble updating Galaxy Note 9

Hi i am new here and need help with updating my Samsung note 9 i still have a baseband N960USQS1ARI5 but will like to update to the latest firmware. i'm using an unlocked AT&T phone. can anyone guide me? I'm not sure if updating the firmware will lock the phone and the process to update, do I just update the firmware in stages as the updates were released till i get to the latest update or can i update straight up to the latest? I am thinking of using Odin, is that a safe way to do this? any help will be appreciated. Lastly, can I change from the AT&T firmware to lets say a none carrier based firmware so as to stop seeing the AT&T logo on boot up? Maybe switch to a firmware that supports global or international? Does anyone have links to an unlocked firmware update i can use, as well? Please help!
I must state that the phone never updates automatically as it always says the software is up to date.

to your last point, at&t phones are notoriously bad at updating
factory unlocked phones will remain forever unlocked and phones unlocked that are bespoke to a specific carrier will also remain unlocked even with Odin flashes providing that the method employed to unlock it was legitimate. Some unlock methods employ root and only trick the phone into thinking its unlocked. Well, once you remove root, and thusly the trick, the unlock is gone. I have ran across rare examples where the person swore up and down that they unlocked their phone with a legit unlock code and that it relocked to a carrier once the sim was inserted and initial programming completed, but i dunno. Sounds weird to me, but every person who said this also said that the phone locked to a carrier other than the one it came from originally. Take that for what its worth, but i still mostly stand by the first couple lines of this section of my diatribe
If you want the at&t crap gone, get the N960U1 firmware and flash it in Odin. You will need the modified version of Odin to flash it so it can ignore the 255 errors the phone throws up from flashing firmware for a carrier (or, in this case, no carrier) on to a phone that it wasnt originally designated (not designed) for
go to sammobile.com/firmwares, get the info for the firmware you want to d/l, get the Frija tool or Samfirm and download the firmware thru one of those as theyre literally 5x faster and flash it

Downgrading to Android 8 without compromising Knox/ Samsung Pay?

Hi all,
My Note 8 is currently running Android 9 (official), with baseband N950FXXU6DSD3. Given the phone is turning sluggish day by I thought it would be a good idea to downgrade to Android 8. Well, I downloaded Odion and the official firmware for N950F but Odin gave me an error. Googled and found it is probably because the baseband / bootloader is l6 and the firmware I was installing was l5. However, I couldnt find any official android 8 version with bootloader l6.
Just wondering if there is an alternate was of downgrading without tripping Knox/ Samsung Pay?
Thanks!

Nope not possible you're stuck on bootloader version 6 and there's no going backwards now!
There is no Android 8 rom with v6 bootloader? Also, if I choose OEM unlock will it still trip my Knox even if I install official firmware?

No OEM unlocking will not trip your Knox flag. However, if you install twrp and root the phone that's when you'll trip knox. If you're thinking that toggling the OEM button will allow you to downgrade backwards it's not going to happen! I personally don't know of any Android 8 on bootloader version 6. This is why we preach not to accept updates or buy a phone that's already been updated because there's just no going back once you update! We haven't found a way to do that and I don't think anyone is actually spending their time to try to figure that out either.
Ah ok. Thanks. Guess I am stuck on a laggy OS.

Flashing firmware from a different region

Hi all, I'm new to modding in general so there's many things I don't quite understand, hoping somebody can help.
I bought an S10 from a site which was supposed to just send me a refurbed (italian) S10, instead they sent me the US version, (G973U) and I believe it is carrier locked since it's stuck with Android 9 and doesn't find any update.
I have tried searching to no avail what I should flash to simply unbrand it, and allow it to receive OTA updates without tripping Knox.
The build version is the following: PPR1.180610.011.G973USQU2ASGC and the CRC is XAA/XAA/ATT
Thanks in advance.
You shall call them.
Who and what for? I'm past the point of dealing with those sellers, I just want to flash the phone.
CSC (not CRC).
XAA is a multi-region USA ROM, so I don't think it will change over properly for you in Italy. There are threads here for how you reflash a different ROM. The one I used for my S10+ was this one: https://forum.xda-developers.com/t/...e-links-and-flashing-discussion-here.3905897/ but I am sure there is one like that for your S10 non-plus... find it, follow the instructions, and you should be all set.
Thanks! I'm a newbie, what does it mean it wouldn't change properly? No OTAs? Tripping KNOX?
I have found this which seems to be the equivalent of the link you posted.
So, I should flash the U1 version right? However I see only a file "SAU - 1 - ....", and my build number doesn't end in that, furthermore I don't know which bootloader version I'm at.

Oh ok. I couldn't understand first.
For that, You'll flash in EDL mode. But the problem is if your device is powered by a snapdragon chip, it'll not working seamlessly.

No problem. I'm aware of the mode I have to enter to flash, as above I'm trying to figure out which stock rom I should flash to avoid tripping knox, and to receive OTAs. What won't work seamlessly?
Well, mods can close the thread, found the way to do it. Leaving it in case somebody ever needs it.
First, found & checked the bootloader version (5th number from the right in the build version) since you can only flash older bootloader versions apparently.
Then downloaded through Frija the rom for the unlocked phone variant (SM-G973U1) and the unbranded CSC (XAA)
Then using odin 3.13.3b flashed the rom

Hello, I'm in more or less same situation. When you flashed, which files did you use? All of them or just the AP_*** file?
Never mind. Flashed it anyway, now I don't see the AT&T startup screen anymore which is promising. Firmware version is now Android 11 (SM-G973U1 and not SM-G973U) on XAA CSC. Will see if I get any firmware updates later.
