Revert from Android Pie to Android Oreo using Odin? - Samsung Galaxy S8 Questions and Answers

I need to go back to Android 8, but I did the OTA update to Android Pie last weekend on my SM-G950FD.
Can I still flash the Android 8 ROM with Odin, without running into issues with the bootloader?
My current Baseband version is G950FXXU4DSBA and I want to go back to G950FXXS4CSB1.
Thanks in advance!

Yes you should be able to downgrade with the firmware you mentioned. As long as the bootloader version is the same or higher.( in your case 4 ).
You may have to do a clean install (CSC) or if using Home CSC then a factory reset from recovery.
Backup before doing anything first

... and is it possible to downgrade from DSBA to CRL3?
Thank you

I'm gonna try using CSC. Yesterday I tried it with Home_CSC, and the phone got stuck in a bootloop. I had to re-flash back to Android Pie to make it work again.
I'll update the thread to report how it went. Thanks!

According to this: https://www.sammobile.com/firmwares/galaxy-s8/SM-G950F/PHE/download/G950FXXU4CRL3, the bootloader is also level 4, so it should work.

It seems to me, though, that you were told to do a hard reset from recovery.
There should be no problem if Odin told you PASS.
link don't work.

I went back to Oreo CRL3 using CSC, the phone has reset to factory data ... everything is ok.

If you don't like pie I would turn off automatic system updates just in case it wants to update itself again.

Everything worked fine :good: Had to use CSC, because HOME_CSC got my phone stuck in a bootloop. I'd rather not have to re-install everything, but at least the phone's back to working well under Oreo
Thanks again for the pointers!

Just got n910t november n910tuvs2epk2 ota update in 60mb

Just got November ota update in 60mb i am just curious to know if it is gonna lock the bootloader.
UPDATE-/ BOOTLOADER STILL UNLOCKED I TESTED & DOWNGRADED TO 5.1.1 OK1 .
I just received it as well. I use my phone for work so it's encrypted but could you try to downgrade and let's us know what happened
Yes, you can still downgrade to 4.4.4 with the new update
This update should give me enough time to read the details of the update before it reboots my phone in the 25 seconds. At that point, we don't have the ability to "abort" or decline the agreement anyway.
Note 4 tmo, downloads the 60mb update, phone enters recovery mode then i get "update failed phone will recover the original configuration" .
I'm full stock, no root, no custom recovery no nothing. Anyone could help me?
I'd recommend you use the desktop version of ODIN with the latest FULL ROM to restore your device (without wiping) to the version before the OTA update. You can then try the update process again.

I encountered the same error last night. I held POWER + VOLUME DOWN to boot into Recovery mode, then I rebooted to System. My phone went through the app optimization process (you know, the screen that you'd see after wiping the Cache/Dalvik Cache).
I assumed that the update failed, but when I checked "About Device," I noticed that it now has the November 1, 2016 security patch (Baseband Version N910TUVS2EPK2).

Sadly mine didn't, as it gave the update failed it reboot normally without app optimization, checked about phone, no changes.
I gave up and updated through Smart Switch... althought the "dm-verification " error still present.

Well, I also used odin until now. The fact that you tell me there's no "working method " assures me that you made your searches like I did and found nothing.

Stock Android N

So I see a few threads about this being released already and on the dev section for N ROMs, I see that you need to have already flashed the stock Android N ROM before flashing the dev ROMs through TWRP.
I've checked Sam Firmware and cannot see an N based ROM for the S7 Edge on there.... Am I missing something?
Also, if I manage to find a download for an N based stock ROM, what are the options to use in Odin?
I've flashed many ROMs in Odin, so should know this, but I always like to be 100% clear, so as to save myself a headache!
you could... download the last BTU mm firmware. then update via ota will pop out directly after you finish setting up your device.

I'm not registered on beta program but I go back on latest MM firmware and my phone is updating now to Nougat
No update for US and I was on the Beta Program with Sprint. So it's not true that all beta testers got it first.
I am from italy when should I expect
In Spain, PHE, we don't have it.
I can confirm flashing BTU will give you Nougat OTA straight away
Can I flash 6.0.1 BTU without any issues if I am on the first 7.0 beta firmware?

If you flash BTU that changes your CSC so yes you'll lose your data. There was a trick to export, alter and re-import your CSC which is covered elsewhere in this forum but I don't know ify it still works

Stock Firmware for L29C567? Phone soft bricked!

I was installing TWRP and superuser and something failed. Now the phone soft resets and bounces between TWRP and Huawei eRecovery. Does anyone have a L29C567 firmware I can flash? I've done some searching and there doesn't seem to be any sources for the firmware yet. Just trying to get the phone working again.
I think I could use FunkyHuawei if they had the firmware but I don't believe they do yet.
Edit: Looks like I put this in the wrong sub forum, sorry
Please be patient. Soon enough it will be available.

When that happened to me I flashed the update_full_hw_spcseas.zip folder through dload (vol up + down + power) to get the phone booting again.
Try this guide,it will change ur region to Asia C636 but the phone will work 100%
You can rebrand later when official USA version is available.

Yes I did this last night but now I'm stuck on B110. When I tried to flash update_full_hw_spcseas.zip my update restore failed and I got stuck in the bootloop again. I was able to dload B110 again so the phone is running but not sure how to get to B136 or B138 or even B158.

Do you have all apps and themes installed or they are missing?
To update use system update,try with wifi and 4g, there is 3 dots in the upper right click download latest package.

I lost all the google apps and the keyboard when I tried to updated from B110 to B136 using step 7 "flash hw_data" but got it all back when with dloading back to B110.
I'm trying the updater now and it seems to be updating to B158! will update.
Update worked and I'm now on B158 which is awesome! The only thing that's odd now is that my MEID is 000000000000. I'm not sure if that's a big deal.

Step 5 to 9 is to restore the Missing application and data i recommend do this steps again.
If you have boot loop boot to stock recovery and do factory reset.

1- restore oeminfo for C636 http://www.mediafire.com/?szws87sk7rrkqr6
2- download c636 offline firmware,and flash it from an sd card using 3 buttons method by dload folder. https://forum.xda-developers.com/mat...4/post70465883
3- factory reset from settings.
4-use system update to get the latest firmware.
Basically gm007's but skipping a few steps

The update you got via system update is a small update or full firmware?

Yes, you can use this and flash back to Nougat.
Yes, this is bootloader version 3, so you won't be able to flash back to any previous build in bootloader version 2.
No, it won't break any future OTA updates. If you do experience any problems with OTA updates, I do have them available to flash manually, if needed.

Make sure your phone is in download mode. I'm about to give this a go when I get home tonight. There are lots of little things about Oreo that I don't like.
Should be flashing all files that match up with the slots in Odin. I don't think the HomeCSC is absolutely needed (I believe it preserves your data, not sure). I've never used it before. Just know this will erase everything on your device.
My phone is currently bricked, or at least I believe so. It was bricked before and I flashed a different firmware, and after I had it working I upgraded all the updates through the phone to Oreo, from Nougat 7.1.1, and then tried to root it which was stupid on my part, now the firmware that un-bricked my phone won't flash again and it stops after it says xbl.elf. Also on my phone after it fails it says something about SW Rew 3 > binary 2 or something along those lines. I believe this is happening because the firmware I am trying to flash that worked before is now older or something, and right now I am downloading this firmware to try it out.
I have tried flashing this onto the phone, the first time everything went fine, but then when the android came up it said Error..., then it just goes to the charging circle but it doesn't show what my battery is at, and also what I have noticed is my phone will not go into download mode or do anything unless it's plugged in, I have no idea what to do as of right now.

Make sure your phone is in download mode. I'm about to give this a go when I get home tonight. There are lots of little things about Oreo that I don't like.
Should be flashing all files that match up with the slots in Odin. I don't think the HomeCSC is absolutely needed (I believe it preserves your data, not sure). I've never used it before. Just know this will erase everything on your device.

Had a couple of scares but it worked fine.
1. After selecting the files in Odin, it took a while for a couple of the files to populate into the slot. Wasn't expecting it to take so long to analyze the files.
2. After it finished, there was a pause at 32% on the phone saying there was an error. After a minute or so it rebooted.
3. When it rebooted it went to a screen saying the phone was encrypted and to enter my password. I had never encrypted the phone, plus, I had done a complete factory reset before flashing in Odin.
The solution to fix this was to power off, boot to recovery, factory reset and clear cache. It booted up fine after that.
Now I'm back to what I wanted. I had purchased Package Disabler a while back so I first installed that and disabled software update so it won't upgrade to Oreo.

No. Read my last sentence in my last post. I did all this so I could go back to Nougat and stay there by disabling the software update. I did not like Oreo. I didn't like the way notifications were changed for Oreo. Badges were tied to status bar notifications, unlike Nougat.
Plus, my phone didn't feel as smooth in Oreo and my battery life was worse.
I'm staying on Nougat for a while.

My phone is not unlocked. The UI in Nougat and Oreo are very much the same. There are some features that are different to each one.
I don't see how you can upgrade to Android P. Oreo for Samsung was just released back in March. Unless there's something I don't know, P won't be released for this phone for quite a while. But I hope I'm wrong about that.

If you downgrade to android 6 you need to factory reset which you obviously cannot do because you have an MDM lock.
Why does this tablet have MDM software installed is the question?
Also I can't see how you have managed to get FRP locked when you have MDM as this prevents factory reset unless you have installed a custom recovery or something?
In that case all that is required is to flash the stock firmware.

I have no idea. I bought it like that from some guy in Danmark. Don't think it was stole though as I know the guy, and I don't think he would do that. Do you have any suggestions of how I can unlock it?

I need to know the current situation. Have you flashed the stock firmware successfully and managed to boot with FRP Lock off?

I can boot into the starting/introduction screen (only on android 7 versions) but after I connect to the Internet and agree with the terms of usage, it wants me to enter the email and password used earlier for the device.

So this means someone has somehow managed to factory reset via recovery triggering the FRP lock.
How considering it is already mdm locked is a mystery?
There are ways to get by FRP using accessibility mode, but the firmware would need to be downgraded to the earliest possible.

The earliest I could downgrade to was PL4 but it just straight it gave me a black screen asking for a password. Though I can flash any Android 7 Rom for the tab.

The problem is if you try to downgrade the os version you need to wipe the data partition.
You cannot do that because of mdm.
What's the full firmware build number?

OK you will need the 5 part repair firmware. I'll post a link to this later.

OK just re-read your post, you already have the correct firmware.
When flashing the firmware flash CSC instead of HOME_CSC.
This should wipe your DATA partition and remove the MDM software.
Check repartition in ODIN when flashing. It should find the PIT file in the CSC file.

Yes, also check repartition. Note you will lose any data stored on internal storage.

I flashed it successfully with the CSC and repartition checked. It sent my straight to recovery then I tried to factory reset and it still said MDM does not allow factory reset

It should have auto booted to recovery and then you should have seen 'Erasing'
Did you flash the whole firmware including CSC?
Can you upload the CSC so I can take a look at it?

I'm not home right now. From what I remember, it was just a normal recovery with the ADB option, factory reset and Cache reset. I'm not home right now.
