Problem with downgrading S8 - Samsung Galaxy S8 Questions and Answers

Hello,
Recently I've updated my Galaxy S8 g950fd from Android 8.0 to 9.0, however i found it terrible and I would love to go back to 8.0. I've read many topics and all of them states that I have to downgrade it through the Odin. I've downloaded a few softs from websites:
SM-G950F_1_20181227130827_c3nriwjmas_fac
G950FXXS4CRLB
G950FXXS4CRLB_G950FOXM4CRL1_LYS
G950FXXU3CRGH_CL14023573_QB19093103
G950FXXS4CRLB_G950FOXM4CRL1_LYS
G950FXXU1AQG5_G950FOXM1AQG5_ZTO_4file
And non of them works. Odin keep showing FAIL message, phone stuck on bootloop and the only software I can use is 9.0 ( G950FXXS5DSF1_OXM5DSF1_(SM-G950FD))
At this moment I'm downloading 2 firmwares from sammobile.com website: XSG-G950FXXU4CRL3-20181218135110 and XSG-G950FXXS4CRLB-20190128142840 and I hope they will resolve the issue I'm facing.
What am I doing wrong? Is there any other way to downgrade my phone?
Thanks a lot for replies!

Your bootloader version is v5 and all other firmware including previous pie and all Oreo firmware are at v4 . If u installed June or July update on your phone then u can't go back anymore and thus Odin keep faling for your

What about going back to 8.0 through TRWP? Impossible?
I've found this thread: https://forum.xda-developers.com/galaxy-s8/help/s8-downgrade-version-9-t3922577 and I've downloaded G955USQU5CSA4_G955UOYN5CSA4_CCT.zip

G955USQU5CSA4_G955UOYN5CSA4_LRA.zip
G955USQU5CRK1_G955UOYN5CRK1_TMB.zip , however when I try to install s8+ firmware through Odin it keeps showing FAIL. Damn.. No other way to go back to 8.0 than new phone?

I've found Lineage 15.1 OS with bootloader v5 on android 8.0 however I am struggling now with installing TWRP. Keep getting FAIL in ODIN and note in phone: Only official relased binaries are allowed to be flashed (RECOVERY). I've tried to reset cache, perform factory data, OEM is enabled and usb debugging as well. I don't know what's going on to be honest and after reviewing thousands of posts - I can't fix that issue.. My current software on my g950fd is G950FXXU5DSFB Android 9.0.
Is here anyone who can advice me what should I do? I would really appreciate that. Thanks!

Anyone?

Sorry can't help you with that much, it seems u did all correct steps for rooting the phone. dunno why u get only official binary message.
Edit:
Post your issue here, maybe someone here can help you more

Good News Guys >>>>Official T-Mobile Galaxy J7 Android 7.1.1 Nougat update released
We reported recently that the Galaxy J7 might soon receive the Nougat update. The handset was spotted at the Wi-Fi Alliance running a Nougat build. It was a big indication that the company was planning on rolling out the update soon.
T-Mobile has now started rolling out the Android 7.1.1 Nougat update for the Galaxy J7. It’s one of the few devices that Samsung has updated straight to version 7.1.1 from Marshmallow.
T-Mobile Galaxy J7 Android 7.1.1 Nougat Update
T-Mobile has started rolling out the Nougat update for the Galaxy J7 over-the-air. However, the company’s support document for this handset is all over the place. It assigns version number Android 6.0.1, Android 7.0 and Android 7.1.1 to one single firmware version, J700TUVU3BQI5.
This is obviously not possible. Clearly, there are clerical issues with the document. That doesn’t mean the T-Mobile Galaxy J7 Android 7.1.1 Nougat update isn’t rolling out. Those who own this handset on T-Mobile will soon receive an update notification if they haven’t already.
This firmware is also available for download from our firmware section where the Android version is accurately mentioned as Android 7.1.1 Nougat. Despite the fact that this update has been released in October, it comes with the August security patch.
Galaxy J7 owners on T-Mobile can either wait for the update to go live in their region or simply download the firmware from our website.
Download 7.1.1 here and happy flashing J700TUVU3BQI5 - Galaxy J7 SM-J700T TMB USA (T-Mobile)

Source :- SamMobile
Tmobile received the update from samsung on 8/28. They filled it with their garbage and sent it last thursday, most of us flashed aqf1 stock and got it ota friday morning.i dont see any clerical errors or anything like that at all. And ive been digging through the build for a week. Im running it now. All internation j7 roms flash with this builds kernel, but reboot in the setup wiz, so once we get a good base there will be a ton of ports in this community. Also, we have found, edge screen, blf, high performance mode, and aod hidden but inactive in the phone. This build is something amazing folks.
Btw, sammobile is a useless, slow dinosaur. Updato via playstore is the best source for firmware.

Safe to flash through TWRP while rooted with xposed? Or should I disable xposed and uninstall root? Also, should I wipe when flashing or does it matter

U cannot in any capacity flash a stock firmware with twrp.u have to wipe your whole phone and go to download mode and flash the firmware via odin. Dont forget to unzip the file first so u have the unzipped form of it loaded in the ap slot
Aight I'm chill (no way at all to update without wiping my phone?) Like what if I don't wipe and flash in odin; will that lead to problems?

U could if u werent rooted or had twrp installed..if u dont wipe before odin, it will prob fail until u wipe it honestly.

how to downgrade from official 8.0 to 6.0

I try with Odin but it is not...please.
Try to download latest 6.0 frimware but I think bootloader is locked and it's impossible.
Have you tried with ticking bootloader option i Odin ?

I believe i read somewhere on here that you can only flash the same bootloader version as 8.0 is version 2 so the only one you can downgrade to is one with bootloader version 2 and that is 7.0 i understand. Correct me if i am wrong though,

Find 7.0 Firmware that is at least March 2018 or newer (Binary 2 Rom) to downgrade from 8.0 Oreo

Just download the firmware for 6.0.1 and flash it in odin, I've done it several times and it works very nicely.
I'm surprised they would allow 6.0.1 firmware to flash what model is your phone sm-g935f and was it on 8.0?
BL code drops to 6.0 without code but network goes

yes only the latest 7.0 firmware
Hello,
I downgraded to 6.0 but phone is now stuck in boot loop and i'm unable to access recovery mode.
I'm only able to access download mode.
Please how can i resolve this problem?
Hey guys, who knows do we have option like — flash fw with older bootloaders and then do isolated new bootloader flash to make older fw work?
Something like that, because i "heard" similar tricks in internet, like people are flashing modem and bootloader bins separately after downgrade flashing like from android 8 to 6. But didn't find proper instructions on that.
Is it possible? Is there instruction out there?
Yeah, oreo is better than nougat and yeah yeah new features, new updates blablabla. I just believe that every device is always better with its first software - we all saw and know how Apple does, i dont think that other companies dont do something like this...after masscopy of notches personally i dont have any doubts...why you think samsung "upgrades" this bootloader sh*t? It's the same thing like it was with iphone 4s - no downgrade option, and "upgraded" version of fw forcedly reduced the work of processor and other performances - you forced to BUY new one. Same politics in Samsung.
Well, for me marshmallow is better than all others in using S7 - it's faster and bugfree than nougat or oreo, yes it's oldy and even some basic performance features not exist, but still android 6 is the best for S7. I used custom roms but they are really buggy, badly buggy, definitely not a choice for everyday using. Oh i missed the days with nexus phones...not pixels.

Yes. It's just not officially released yet. I've been scouring the web for a leak. This means Oreo has been built for our device already and the official release coming. If you're curious about WiFi Alliance, wikipedia has good information about them.

I'm already running Oreo. TWRP has problems with it. I can't make a backup of the OS. You can restore a back up, but you have to flash the BL file from ARG2 then wipe everything in TWRP first. SuperSU 2.82-SR5 will cause a boot loop. I'm going to try magisk 17.1. Honestly, I'm very disappointed with Samsung's Oreo... It's almost the exact same as Nougat, and the new camera sucks, very bad. They gave us Nougat, with Oreo 8.1 as the base firmware. That's my literal take on it. I'm definitely getting a Moto G6 after seeing this, and I'm going back to my stock build.

I have, and flashing back to nougat works fine. You have to flash ARG2 for it to work, and you can't downgrade the Modem. I'll put together instructions and probably a debloated ROM later this evening, and I'll get the firmware uploaded ASAP. Some notes, clearing the camera data fixes the blurry image problem, and it can be rooted. You need the latest TWRP, and Magisk 17.1 stable. You must flash TWRP, swipe to allow modifications, then format data with the option that makes you type "yes", then flash magisk. Root works perfectly. No issues. I'm debloating the OS right now. I'm about to test Viper too. Its actually much faster than Nougat once the junk is out and yes, it can be fully deknoxed. This might not be so bad. I'm still disappointed with their lack of Oreo-esq cosmetics though.

I've got 3 of 4 firmware files uploaded. The AP file is giving me trouble cause my WiFi sucks, and it keeps failing before it finishes. I did put together a full stock Oreo ROM but its got problems. You can only flash it using TWRP if you have the ARG2 bootloader, but, the ARG2 bootloader, won't allow Oreo to boot up no matter what. We'd need a custom boot.img and I can't make one. The ROM can't be flashed with the Oreo bootloader installed either, because it prevents TWRP from copying/writing to the data or system partitions. If it tries to, it'll reboot half way through. Magisk 17.1 will also lose root after awhile. We need a custom boot, or we need a modified root method and an updated TWRP to have any fun with it. SMH at Samsung right now. They gave us Oreo, with no milk, and a slap in the face. Nougat everything, running on Oreo 8.1 firmware... I'll never get over that. I'm running an ARG2 build cause everything works, and largely looks the same. I swear, they didn't even try. They just reskinned some Nougat apps and put them in an Oreo system. I will never buy another Samsung product after seeing this half hearted Oreo they gave us.

Dear Sirs;
Having had to replace my originally bought (Nov 17, 2017) J7 Perx from Boost, then bricking it and replacing it with a Galaxy S6 refurb from Boost, which was then STOLEN by a "friend" of 6(six) years, has been replaced by a NEWER J7 Perx. This device received at lest 3, if not 4 OTA updates, one of which was a supplemental firmware/software update. About Phone (and Samsung INFO app) NOW reveal the following detail:
HARDWARE VERSION; J727P.02
Mfg date; 03/15/2018
Software Version; J727PVPU4BRH5
Android Version; 8.1.0
Samsung Experience; 9.5
Baseband Version; J7272PVPU4BRH5
Build Number; M1AJQ.J727PVPU4BRH5
Android Security Patch; August 1, 2018.
If given instruction and link to necessary utility to extract the firmware from my device to my PC, I would be more than pleased to provide the files(s) procured from that process.
I look forward to hearing more about possible deodexed firmware to ROOT my newest device.
A custom ROM would be nice, too.
---------- Post added at 15:23 ---------- Previous post was at 15:14 ----------
Guess I should have browsed a few more posts before posting.
I found the link to all the 8.x firmwares for the various models, and must say "Bravo!" for the Herculean effort expended to collect, upload and make all that available.
Thanks!

Super lag after unroot and bugs

Hi everyone,
I brought this phone from a phone store (not official), and it's second hand. The problems are common, LAG.
And sometimes, when i start phone data, my SIM signal suddenly stopped…
And I found that this phone had been rooted before and unroot for being selling.
I knew knox had broken.
It's common ROM same as others but it was LAAAAG.
[SM-G935FD], my phone model.
[Android 6.0], my android .
I've tried to reformat and recovery mode wiped before. And it's useless.

Hi everyone,
I brought this phone from a phone store (not official), and it's second hand. The problems are common, LAG.
And sometimes, when i start phone data, my SIM signal suddenly stopped…
And I found that this phone had been rooted before and unroot for being selling.
I knew knox had broken.
It's common ROM same as others but it was LAAAAG.
[SM-G935FD], my phone model.
[Android 6.0], my android .
I've tried to reformat and recovery mode wiped before. And it's useless.
Any suggestions everyone?

Update your phone dude it's on old android 6.0 .upgrade it to oreo 8.0 via Odin and that should fix your issue ,even tho it shouldn't lag like that on any android version.

Hi! Thanks for your reply!
But where should I get it? And does your "Oreo 8.0" belongs to official or Properties Oreo 8.0?

It's not my Oreo ,it's Samsung official firmware 8.0 Oreo . First learn how to flash something with Odin then download official firmware from sammobile or updato site. Put your phone model inside and start downloading

Wow! That's mean Oreo 8.0 are available for officially download?!
I'm clear on how to flashing ROM with Odin…but I'm not sure with how to get official ROM.

Downgrade Samsung Galaxy S7 EDGE

Hello guys! I would like to downgrade my Samsung Galaxy S7 Edge to a version where I have the outdated security patch, preferably in the May 2018 version for me to play Pokémon Go. However, I downloaded a ROM of that date but when it was installed, the security patch remained the same, February 2019. I am downloading another ROM, but with the android version 7.0, but if anyone can help me in knowing what the problem is, thank you!
