Downgrade S9+ to Oreo - Samsung Galaxy S9 Questions & Answers

Hi,
I just got an S9+ and I really don't like One UI, and I've seen lots of tutorials on how to downgrade to Oreo, though for me I keep getting stuck at recovery.img in Odin and I don't know why. I have tried both BTU and VOD firmware (not sure if my phone was locked or not and I'm in the UK) and nothing works. Please help.
Thanks,
Marco

what error is Odin kicking up when you do this? something about the binary? what firmware are youstarting with and what are you trying to flash exactly?

So Odin isn't kicking up an error, it just gets stuck on recovery.img every time no matter what I firmware file I try. I am starting with the latest Android Pie One UI firmware and downgrading to Android 8.0 Oreo using firmware from samfrew.

thats why i was asking for the firmware version youre on because it would have told me if it was a U or an F LoL. which is totally different from a F and a U (get it? F U?) bad joke... anyways, the F might be able to roll back, but the U for sure is not. Im not well enough versed to go much past this point as i am of the belief that you cannot downgrade, but i could be wrong and dont want to discourage you. Anyways, the entire firmware version youre on and the one youre trying to go to would be helpful. You cant just say "the most recent" because there are many versions of "the most recent" version. Absolutely not trying to mock you or anything, but trust me when i say to post up entire firmware versions, its helpful to those who come to this thread and would like to help out, but dont have the info they need in order to do so

Ok just did a quick bit of Googling and I'm on the September 2019 Security Update (Android Pie) and I'm trying to downgrade to the November 2018 Update (Android Oreo). Thank you for your patience I'm a complete novice here!
Edit: I've also tried using a patched version of Odin and unfortunately that also hasn't worked

no worries man. grab your phone, go to settings/about phone/software information/baseband version
what is the baseband your phone is currently on and what is the entire alphanumeric of the firmware youre trying to flash?

not a problem
the bootloader you have on your phone is version U6 and the one youre trying to flash is S2, thats 4 revisions back and im sure thats part of the trouble youre having. Im going to have to look at downgrade procedures in order to find out if its even possible. Kinda surprised that someone else hasnt popped in here such as @The Mad Scientist
---------- Post added at 01:35 PM ---------- Previous post was at 01:29 PM ----------
here is the thread discussing how to do it, but the examples in the guide show far older bootloaders than what youre running. you said that youve seen tutorials on this, do you have any links?
also, the baseband of your phone is from Germany, have you tried a German 8.0?

Two things, 1 that link is the exact one I used first and second wow I never knew I will try a German Android 8.0 thank you do you know what code those ade? (E.g. BTU or XEU idk what these codes are called)

here is the most recent German 8.0
https://www.sammobile.com/samsung/g...e/SM-G965F/DBT/download/G965FXXS2BRL3/249034/
also, if Odin stalls at initializing, then its probably not interfacing with your phone properly. Does it show a device listed as "COM:#"? that pound sign is going to be a number, doesnt matter what that number is, just as long as Odin says "COM:3" or "COM:733" in that little box below the big one in the upper left hand corner

these phones are a major learning curve, thats for sure. Ive been rooting and modding phones since the Droid Incredible and HTC Evo (the original evo) days and its just a different world, which makes sense because these phones are asked to do sooooo much more than the old school smartphones ever did. Anyways, those 3 letter codes are called CSC's. "Consumer software Customization" is what they technically call it, but ive ever only heard them referred to as "country specific codes" which makes more sense as theyre bespoke to a country.

Ok so Odin recognises my device correctly, however the issue then is still it getting stuck at recovery.img, even with the German DBT firmware. Really weird

Damn is there any way to downgrade the bootloader or trick it into running Oreo? How else would other people have downgraded as I'm assuming the bootloader version changed between Oreo and Pie.

nope sorry, only way is oreo custom rom. try tgp oero

I think you flash PIT file with it? If you did just go to recovery and factory reset and your memory should be back.

Yes, it works. I have just updated my N920A from C6 to D1. Don't forget to backup your data first.

thanks!, last time i did adb sideload (C6 to D1) and i got problems wich home and power button, auto press / autoclick it Without having pressed, i think can be google screenseach new function which hijacks the home button and when it is not turned on it does not return to the normal state of the phone
*i solved temporaly doing restore device form options menu, but it reappears from time to time without having pressed, Fixed if you do not configure or start googleseachapp (temporaly)
*Now downloading file and coming soon installing from odin an odin fresh installation from last version is better than doing adb sideload from B2 or older

Downloading this through Odin - would that be considered tampering? - I have had 7.0 on a sprint note 5 and I loved it. I now have an AT&T note 5 on cricket and I have to wait for cricket to come out with the update ... zzz .... does samsung s health and pay still work after flashing through Odin? I'm only using this phone until the new note phones come out, so I don't want to mess up selling this phone by downloading through Odin. - thanks in advance.

OK just to be clear - making sure before I download this since with 7.0 there's no going back - This doesn't trip Knox or Samsung? I don't want to mess anything up just want 7.0 now instead of waiting months or so for the update through cricket. Thanks in advance. Also, I seen a post say this is just a partial/half of 7.0 is that fixed or us this still just half of the 7.0 upgrade?
can someone make a google drive mirror? because I have 1gb limit in mega

No. This is an official ROM with matching modem bootloader, and recovery. It will not trip Knox.
ok last question - is this the full 7.0 now? I see the title says full but there was a post saying this was just partial of the update.
Yes, this is the FULL 7.0
hello.
im a newbie to samsung and odin although i have had success with other samsung phones and odin a while back and after reading tons of info this is where i am at :: (i know the nougat file isnt the same but im guess the procedure is the same) . i read that updating via odin you can jump basebands, however im guessing that is not true. my baseband ends en 3BPH4
i downloaded >> Nougat_N920AUCU4EQC6_Odin_Files.zip (2.0G) <<
from here https://www.androidsage.com/2017/03...ndroid-7-0-nougat-ota-n920aucu4eqc6-download/
fyi >> im using virutalbox windows 7 and odin to try to do this <<
after i unzip the files i get four tar files
AP_N920AUCU4EQC6_CL10809541_QB12921033_REV00_user_ lo w_ship_meta.tar
CSC_ATT_N920AATT4EQC6_CL10809541_QB12921033_REV00_ use r_low_ship.tar
CP_N920AUCU4EQC6_CP6021124_CL10809541_QB12921033_R EV 00_user_low_ship.tar
BL_N920AUCU4EQC6_CL10809541_QB12921033_REV00_user_ lo w_ship.tar
i select each one as per requested slot in odin and then hit start and then odin crashes.
since that didnt work i opend the ap.xxx.tar.rar for the ap slot and hit start. there was some activity int he odin message box. firmware update start. single download..... and left it like that for over 30 minutes and there was no change. so i shut the phone off and restarted and nochange on the phone.
THEN i opened that ap.xxx.tar.rar file and saw that there was tar.md5 file inside. extracted and repeated the process and since i dont have a pda slot i choose to open under the ap slot.
so far same deal. odin message says NAND Write Start.
(im starting to believe that headers are not correct and doesnt want to follow through withe update)
if someone can guide me in the right direction or help where i went wrong. do i really have download 20gb of 10 updates for each step by step update to get to nougat and adb sideload?? cuz that is crazy. any help to get my note 5 lolipop to nougat is much appreciated.
also, if there is any knowledgeable buddy out there, since im on the 3BPH4 endind baseband is it rootable? (without loosing root when you reboot)
either way i dont care much about root but would definitely like tobe flashin roms etc, but as for now i just want to get to nougat

root info?

Hey all!
I'm new to Samsung completely, I have experience rooting, as I've had multiple Nexus devices, and other rootable phones. Just never had a Samsung. I recently took the Oreo OTA update, and was wondering about the best rooting method? Ive read that you lose secret folder. Is there a way to keep that?
Basically I just want to debloat more and theme without having to use Andromeda, as that is annoying.

Yes it will work fine on oreo, as long as the 2nd to last number of the version you are on isn't a 3. Example:
Good: G950USQU2CRB7
Not Good: G950USQU3CRC6
^-- That right there is a no no for now
But afaik there is so rom in existence for 950u with a 3 there. Just something to watch for in the future.
You don't need to flash back to nougat stock first either. Your should be able to go straight to pcr. If you have trouble with the first step you can try flashing part 2 first, followed by 1 then 2 again, but i fine expect you will have any issues.

So basically what I'm gathering is, it downgrades the bootloader or kernal to a rootable state, then with wizardry I can flash a Oreo rom?

Not exactly, this is a root/rom combo. So it will downgrade you back to Nougat version 2 bootloader firmware, root your device, and flash a ROM all at the same time. So there is no way to flash a different ROM since the rooting process and ROM flashing is built into one step.

True, but if anyone is still lucky enough to be on version 2 bootloader on Oreo they still can downgrade to Nougat version 2 bootloader and use that Root/ROM combo to root their device since it works on ver. 2 bootloader but not 3. And yeah, screw Verizon!

Yeah its flashing an engineered firmware, and it trips knox which is needed for secure folder I think. I looked on my S8+ and couldn't find secure folder anywhere, so I'm guessing the ROM removes it.

Whatever happened to those days. S**t, the last few ROMs I was flashing on the N6 were all pretty much the same. I miss being pissed off that one rom had all the things I wanted but looked hideous. Then everything got CM based and themes were everywhere. Then it all just got the same. Then it all got locked down. Almost like Android and Google were playing the devs getting them to make the mods, then them steal them, and incorporate them, then lock it down.

I'm sorry for this basic question, but does the phone being carrier unlocked make any difference? I know that has nothing to do with the bootloader; I'm simply asking if the phone not being Verizon-specific has any effect on rootability ... I was just about to purchase an unlocked S8+ when I saw this thread and almost spewed Mountain Dew all over my monitor. I had no idea Verizon had squelched root, although no surprise there, right?

if its unlocked and international version, and you use it on verizon, you can still root without any problems from verizon. only verizon variant there is that crappy problem

Yeah there is root for all carrieres (verizon, tmobil, sprint, att) but its limited and the bootloader is still locked. I would still get a the international version, better root, more Roms, etc...

When you say international version, is that simply the carrier unlocked version? And do you know if there is a certain model number or letter designation after the model number I should be looking for? I'm shopping on Swappa and eBay and need to be really careful. Thank you for the help, by the way.

Need help finding the latest rom

I may have bricked the chooch out of my s7 active was wondering if someone can give me the latest version or a backup of the latest version haha (tried to install oreo) NRD90M.G891AUCS2BRC1 is the build number
For bootloader 2, I think the latest full ROM available is BQD4:
https://cloud.mail.ru/public/BGy7/gKs4xzhRE/firmwares/Nougat/G891AUCS2BQD4_7.0_all.7z
Warning, this only applies if you are still on bootloader 2 and haven't gone up to the latest version 3.
YO thanks for the quick reply the room my phone wants
G891AUCS2BRC1 that'd be the latest official update
I guess you need to install BQD4 above, and then work your way up with the OTA files on that cloud page to reach BRC1.
Only issue is the bootloader Is locked so I can't downgrade it to brc1 lol the bra update just came out a couple days ago ,thanks man for helping me out by the way very cool of you

No problem man, I hope it works out for you.
The thing with the bootloader is that it has been on version 2 for quite a while, but in the most recent updates it became upgraded to version 3. You can see it in the file names. For example G891AUCS2BRC1 is still on version 2 while the most recent full Nougat ROM G891AUCS3BRD1 upgrades bootloader to version 3 with no turning back after that, as far as I know.

I was wondering if there where any tech savvy people on here that would know how to fix this problem. I know the Imei and if I fastboot getvar I can see the iemi. Plzz help thanks.

Just flash stock firmware. thats a pretty big mistake to make lol I'm pretty sure I made it quite clear in my guide to backup at least 2 or 3 times. But just flash stock firmware using the commands at the bottom of my guide. Even if the bootloader is locked the commands will work to reflash it still. The need links for stock firmware is also in the guide. And I will say this. If you took the newest update before rooting then you will have to wait for that firmware to be uploaded because its not uploaded yet.

The newest build is only a few days old so it will be nearly impossible to find online. And it has a different baseband and radio than the previous build. But the October update is OCP27.91-150
As long as the imei isn't zero you should be able to get service back. I had the same issue when I flashed an older firmware like a moron. But when I took the update again, I got service back. I don't recommend it because I may have just been lucky, but no matter what don't flash the gpt, asdspo(?) And bootloader with the older firmware. It'll mess your life up.
Ok i guess ill have to wait it out. Tried to flash stock and still unknown imei and no base band version so guessing it was updated. Thank guys!

Try taking the update again over WiFi if you can. You shouldn't have an issue as long as you're back to stock. But the update is only 3 days old so you may have a chance.

@ninjakira Would my modem.img backup be of any use here? Or anything else? I don't know what is stored where.

At this point no it's gonna need a full reflash of the firmware. I was having issues with my service and went and flashed the OEM file from the 2nd update through fastboot and did the erase carrier command and got my service fixed. Could try that.

If you have the xt1922-9 then that means you have the att version if I'm not mistaken. If so just go to the links in my guide for stock firmware in the att folder. It has both the firmware your on plus the updated firmware from September which is ocp27.91-62-3 plus my guide will help you achieve root. Just please read it all

I flashed bout those firmwares and still nothing i dont understand whats going on or if im messing something up somewhere in the process. It flashes an everything seems to be ok other than the Imei unknown which causes the phone not to read my sim card if im not mistaken. Thanks for taking the time to try and help.

Baseband is software. Radio is a piece of hardware. The piece of hardware that gets your carrier's signal. It can't be upgraded without physically altering the phone. Even then it would need to be the same exact radio because the stock drives probably wouldn't work, and the chances of a dev making a version for 1 person with a different hardware would be slim to none.

Try flashing stock firmware. If that doesn't work there are other options still.

You were flashing a gsi not a rom. Even then a rom and even less so a gsi, doesn't contain all the same data as what stock does.

Cricket S9

Im wanting to de-Cricket my S9
Its a G960U, so i assume that all i would really need to do is flash the U1 firmware, correct?
and if that is correct, it will give me a Sammy splash screen and boot animation too, yes? Perhaps some sophomoric questions, but im just making sure.

Yep that's right, it will remove all the carrier crap (I assume splash, definitely boot), just remember about the bootloader/baseband versions that cannot be downgraded so if you flash to version 4 you can only flash v4 or above after that
You will also receive updates direct from Samsung instead of the carrier

Yea, version number is here
G960USQ>>S5<<CSEA
So as the U1 firmwares are all stuck on version 4 you cannot flash them right now

damnit. thats just my luck too :/ thank you for affirming my understanding of how this works. I came to the S9 recently but i do recall the odin flash process for the t-mobile S2's that required the individual files to be placed in Odin before flashing, so this is all old hat as far as the process goes. Any idea on how long it might be before the U1 firmwares are going to be available for V5?

Only Samsung knows, but a lot of firmwares are now on v5 so if I had to guess I'd say the next update probably will bump it up to v5, they said the security updates included in the June update required it to be updated
When it receives the next update is anyone's guess though
And yes, all 4 parts of the firmware to be flashed together in the corresponding ODIN sections, HOME_CSC will not reset the phone, CSC will reset it, use one or the other in the CSC section

Creators of the tools would have to request that, they're easy enough to find with Google if you search "samsung firmware download tools xda" top results have both of the tools
