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,

Correct.
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

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.

Wifi models don't have locked bootloader but LTE models do.
Downgrade firmware to Android 6, you need a version closed to the release of Android 7. It will fail if you're flashing older firmwares.
I have no problem of downgrade from QF1, Android 7 to PL4, Android 6 ( US firmware ).
You can try this one, region doesn't matter.

It seems you have the latest United Kingdom firmware, unfortunately this one blocks any downgrade attempt, even to the older Nougat versions

i am new here and bought a t585 lte with oreo. as far as i read the threads there are problems with lineageos 14. but right now it works besides the screenlock problem. is there any known and working solution?
Hi,
I was wondering if there is a way to go from the P Sprint firmware to U firmware. I want to be able to root my device on QL1. The guide on the forum is for U firmware, but I attempted with my stock Sprint firmware and the only thing I couldn't get to work was mobile data, as APN settings are not adjustable on stock firmware. Is there a way to flash U firmware if I am on stock P?
Thanks,
csmyka

It is possible if your bootloader version is lower than 5, firmware for unlocked version have latest bootloader revision 4. Sprint updates bootloader just to remove this possibility of crossflashing. You are on QL1 version so is not possible at the moment

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.

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

Hello everyone. Long time since i post.
I have serious problem. For some reason im not satisfied with a video performance and batterylife on Pie, and i wanna move back to Nougat (not Oreo). Yet Odin seems dosent alow me to do that. Please i wanna know if its possible, wich i presume it is, and what version of Odin should i use ? I do have downloaded 5 files official rom wich i already flashed last year from Oreo to Nougat, but i have problem flashing it from PIE to Nougat. What version of Odin do i need and what setting?

I have bootloader version 4 right now . Is it possible to use Oreo Rom with the same version 4 of bootloader and then i can flash from that too bootloader 1 oreo, and then to bootloader 1 Nougat? ? ?

You can not downgrade bootloader versions. So if your on pie with version 4 bootloader the lowest you can go is the earliest version of Oreo with bootloader version 4. Anything with 3,2 or 1 bootloader can't be flashed.
My god. So there is no Odin way or any other way to bypass bootloader restriction?

As far as I know no you can't downgrade bootloader versions.
Thanks for the reply. I just flashed the earliest Oreo firmware with bootloader binary 4 wich is actually last big change in stable releases of Oreo. NExt 3 releases were only security updates. I cant get lower then that since two more Oreo firmwares before that had BL number 3 and 2 - Nougat starts with 1 unfortunately. I really hoped maybe guys on XDa figured this thing out too downgrade to lower BL numbers, but i guess its not possible. .If i knew that before, i would never upgrade this shi..t to PIe. Hopefully Oreo will do fine now.
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

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?
