Hey,
I have a Note 9. When I updated the firmware (from custom rom, so there is no warranty), I've got the green screen problem, so I want to downgrade it.
I'm not intrested about "it's impossible" comments, because it's a software, everything has to be possible.
So, I have binary version 9, I wanted to flash BL binary 4 and dr.ketan's ROM (Pie version).
I just want to downgrade the Bootloader version to 4, but I couldn't do it.
On S4 and S6edge, I could do it without any problem. On note 9, I can't do it.
Thanks

Hello,
I have Samsung Galaxy Note 8 SM-N9500 HK variant with the latest Firmware and security patch
I bought it since 1 month. eagerly waiting for installing TWRRP and rooting it using Supersu
I tried the following TWRPs through Odin
1-Galaxy Note 8 N9500 Unofficial TWRP Android Nougat 7.1.1.tar
2-Galaxy_note_8_twrp-3.1.1-0-greatlte.img.tar
3-N9500%20Nougat%207%201%201%20Unofficial%20TWRP.tar
4-N9500_TWRP_3.1.1-0.tar
5-N9500+Nougat+7+1+1+Unofficial+TWRP.tar
All these when installed through ODIN showed "PASSED" in Odin. but failed to install in the phone, I can not reboot into recovery.
Then I got the following 2 TWRPs
6-N8-TWRP-835-3.1.1-1-greatqltechn.img.tar
7-N9500_TWRP_3.1.1-0.tar
Both installed , I swiped for system modification, then wiped to factory reset, installed SuperSU, but failed to reboot into system. it is bootlooped in recovery , I have to flash my stockrom to recover the phone.
So if anybody have the knowledge how to install the correct TWRP and root this variant , kindly help me and others who are in the same situation. It will be great help if they can provide the links for downloading the necessary files
Thanking You all very much

I'm currently on 8.0.0 version and I want to downgrade to 7.1.1. I need help with the downgrade version
I've tried N950USQU2BQLA and N950USQU3BRA9 and both failed.
My carrier is TMOBILE
Your 8.0 bootloader version is 4. You are trying to downgrade to a lower version. You can't.
And next time please read and search. The phone is now 8 months old, plenty of info out there !

If you don't mind me asking, why would it be impossible to downgrade if he's on U4? What would cause the process to be impossible?

What he wants is to downgrade to 7.1.1 which is possible if he is on u3(keep in mind i am referring to the bootloader version). On U4 there is ONLY 8.0. They did not release a 7.1.1 on U4 bootloader. Any time there is a major bootloader revision(such as u3 to u4 bootloader) Samsung blows a qfuse preventing older firmware from being installed(you can only flash firmware that is on the same incriment or newer) meaning if you are V1 bootlaoder you can flash either v1- v4 HOWEVER the moment you flash a higher version(if you go from v1 to v2) you are now stuck on v2 and higher and can no longer flash v1.
Based on the OPs provided information I assume he is on v4 bootloader because he is unable to flash v2 and v3 firmware. Because he is on the v4 bootloader he cannot flash 7.1.1 firmware which was last on U3. At this point his only option is to stick with U4 firmware(8.0 only).

Thank you for explaining this to me. It makes sense.
EDIT: I Google'd how to check which bootloader you' re on, and actually found a bunch of articles that seems to explain what you just did, along with being unable to flash custom ROMs.
I need to go from 8.0 to 7.1.1 too
Hi guys I upgraded this evening from 7.1.1 bqk2 to 8.0 2cql1
It doesn't work correctly I keep getting a black screen and the phone vibrates.
The only way I've been able to fix is holding power volume up and bixby and wiping data/factory reset
Is there a link to a download for my software and a guide at all?
Forgive me for the stupid question I can't find any info out there online or a YouTube video
Thanks in advance
Joe

Just to add the reason I'm uninstalling is every time I update the always on display app it is then that I get the black screen and vibrations. Until then it is fine.

Maybe try a factory reset (backup first!), or install a fresh copy of the firmware using Odin. You can find the files for your device/model on Sammobile, and then download from there or through SamFirm.
hello everyone I'm the only one to this discussion to try to understand and maybe solve my problem, currently on the 8th note I android 8 (R16NW.N950FXXS5CSA1) updated by mistake with software sam firm
I wanted to go back to Android 7.1.1 I tried to insert firmware (N950FXXU3BRA8 base) but odin gives me a failed installation, reading here in the forum seems to be the fault of oreo samsung changed BL / CP making it impossible to go back, I tried but I did not found files needed for downgrade thanks to everyone for the answers

Sorry You can't downgrade to nougat because you are on bootloader version "5"! (From your firmware version you are on N950FXXUS"5"CSA1, the number in "" is your bootloader version). Nougat only went upto bootloader version 3.
The current bootloader won't allow it to be downgraded only upgraded to v6 and higher.
There is no files (that I know of) that will downgrade the bootloader. You'll might have better chance on talking to Samsung and see if they can downgrade your phone.

You can't downgrade the bootloader. Period. That actually why they change the bootloader version...to prevent you from downgrading.
I realized that my galaxy note 8 is not Italian but Europe on download mode me other carrier id
when I arrived for fear that it would not work in Italy I updated it with odin definitely wrong to bring it to android 8
Hi,
I have updated my unrooted note 8 to the android Pie but unfortunately I didn't like the new awful UI also I missed some good features in android Oreo. So, is it possible to use Odin to downgrade unrooted note 8. I'm not interested to root it, just want to downgrade it to official Oreo.
One more question, I even liked Android Nougat than Oreo. So is it possible to downgrade from Pie to Nougat using Odin without rooting?
thanks

You can go back to oreo as long as the bootloader is the same.
You'll have to do a factory reset though.
eg.
Oreo firmware: N950FXXS5CSA2
PIE firmware: N950FXXU5DSA2
Notice the 5 before "DSA2" and the "CSA2" that's the bootloader version. So since the pie and oreo firmware has the same bootloader version you can go back to oreo.
You can NOT go back to Nougat different bootloaders.
eg.
Nougat firmware: N950FXXU3BRA8
PIE firmware : N950FXXS5DSB2
Notice the 3 before "BRA8" and 5 before "DSB2" they don't match!
So the bootloader version 5 will NOT downgrade itself to version 3 therefore Odin will give you a failed error message.
To be is a different question . I have a problem, I want flash the rom with pie generic Spain, now I am in Vodafone pie and Odin always say fail, what can I do?, thanks.

What is your csc?
Spain is PHE in multi-CSC OXM
Vodafone is ATL in OVF Csc firmware.
If you used home-CSC and it fails only option is to use the CSC file (this will delete data so backup first.)
The multi-CSC oxm doesn't have ATL csc inside so you'll lose any carrier specific features (maybe???) So do some research first.
CSC Questions
Hello everybody, I've found myself in the position of needing to downgrade from Pie back to Oreo also.
My question revolves around this "MYSTERIOUS" Samsung "CSC" designation, and the difficulties in verifying what I have vs what I NEED
I have an unlocked SM-N950U1 which is currently running on the Verizon network in the United States
I do NOT have any of the Verizion specific features, ie.... "My Verizon" or even "Verizon Visual VoiceMail"
the phone has also been on the AT&T network previously again with no carrier specific features there either.
Since the "secret code" for the dialer didn't work to reveal my CSC, and there is no carrier software version entry in my about phone software information to reveal the CSC either, I downloaded one of the generic "phone info" apps and it reports VZW as currently active CSC on the CSC tab, but then on the firmware tab in the CSC version location its reporting "N950U1OYM5DSC1" and I have found zero reference to an "OYM" CSC anywhere.
I have downloaded both the PIE and OREO variants of the "XAA" firmware for my Note 8
Does anybody have any idea if this is going to be the correct firmware to accomplish this downgrade without bricking this darn thing, I have no interest in root nowadays because the minuses out weigh the pluses and I really don't want to trigger knox and loose google pay or any of my banking apps, but I really do use and need to use the call recording capabilities that still worked in Oreo, and not anymore in Pie
Thanks in advance

Hi, i just came to this conclusion! i am currently running N950FXXU7DSJ1 and odin always gives me error when i try to downgrade. no matter newest or older version. so there is no possible way to downgrade?
What if i unlock bootloader(if its possible for currently last version), change to custom recovery and install any custom rom(nougat?) and maybe flash bootloader via custom rom also? will this option be possible at all?
Hello, I have my note 9 exynos version (country:XSG) Running one Ui (CSFA) Which have bootloader version 3. Now i want to downgrade to oreo (ARL4) which has bootloader version 2. While flashing via odin i had the error “sw rev check fail bootloader device 3 binary 2”.
Any guide/tips will be greatly appreciated. Please ask me for any further information required.

search and read. especially about downgrading the bootloader
I believe, if you have bootloader version 3 it's not possible to downgrade. I have downgraded international unlocked Note 9 back to ARL4 version back in January. There is a huge discussion here on xda how to do it, but unfortunately I think it can't be done in your case.
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.
