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.

PPR1.180610.011.hadesRom_OneUI_v4.0. Is this what you need?

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. )

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.

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

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).

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.

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.

What model do you have? And what firmware version were you on before trying to downgrade? Some firmwares include bootloader updates which cannot be rolled back.
I have a N950F and this is the Oreo image I succesfully flashed "BL_N950FXXU3CRC1_CL13094739_QB17155977_REV00_user_low_ship.tar"
I can flash "COMBINATION_FA71_N950FXXU3ARA5" without a problem which is 7.1.1 But I think it's the bootloader that is giving me issues and since the combination file doesn't include a bootloader (AFAIK) it goes through, but when I try to put in any bootloader from Nougat, the flash fails.
I tried flashing:
-BL_N950FXXU1AQI1_CL12007350_QB14830234_REV00_user_low_ship.tar
-BL_N950FXXU1AQHB_CL12007350_QB14652984_REV00_user_low_ship.tar
and both failed. It's important to note that I'm trying to flash the whole thing, not just the "BL" file. I just pasted the BL file name because I think it holds the information you need.
Ok thanks for providing the info. One more question, what Odin version are you using?

I got Odin 3.13.1 and the ROM N950FXXU3CRDF_N950FOXM3CRE4_ZTO (latest 8.0.0) from SamMobile. When I try to flash I get the "Check Fail BOOTLOADER" message. Trying to uncheck the BL, I get another error but also not able to flash. Maybe my phone has a newer version that doesn't allow it to in theory "downgrade"?
Any solution?

Yes some bootloaders can't be downgraded to earlier ones. What firmware version are you coming from?

@sefrcoko, I'm currently on Android 8.0.0, Baseband N950FXXU4CRG8, Build number R16NW.N950FXXU4CRGA.
I don't know if this is older or newer than the one I'm trying to flash. Is there a way to do it?
Thanks!

Hi, yes you are on the "U4" bootloader and trying to downgrade to the "U3" bootloader (look at those characters in the build numbers, that's the bootloader version). Can't downgrade from u4 to u3 though.

The Exynos models are all bootloader unlocked as far as I know.

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?
Hi.
I just received the Pie update to my Not8 256GB.
First I would like to check the actual version of my phone. I assume it's simple a N9500, but I guess I need to double confirm. How can I be 100% sure ?
Second, current my version shows N9500ZHU4DSE7. From what I have read, it should be bootloader 3. And normally I should be able to downgrade back to Oreo. I am just unsure how, and which firmware I should use.
Also if I downgrade, will I lose the phone internal data ?
Only reason why I NEED to downgrade : the software block to prevent using 2 sims and one sd card !

"N9500"ZHU4DSE7 is SM-N9500
N9500ZHU"4"DSE7 is the bootloader version. You are on ver. 4
You can't go back to bootloader version 3 or below! Bootloader won't allow it!
Fine the last oreo bootloader ver. That has bl. Ver 4 in the firmware.
Yes you would lose your data going from pie to oreo!
The last oreo firmware is N9500ZCU4CSA1 look on sammobile.com for your model and firmware.
Thank you for confirming what I also managed (in the meantime) to confirm.
Losing all data is a NO go for me
I could back up everything with Smart Switch, but not the entire Secure Folder

Which firmware are you on?
If you are on the latest firmware with N9500ZU"5".... you can NOT go back to Oreo!
Or if on N9500ZU"4".... try this below....
Did you try factory resetting your device before flashing that firmware.
Use all 4 files, AP, CP, BL, and with the CSC file (not the home-CSC file).
