Downgrade from Pie to Oreo - Samsung Galaxy S8 Questions and Answers

I've been trying to downgrade from the latest pie release but I always get the same error due to how Samsung has blocked bootloader downgrades. Is there anyway around this or am I stuck on Pie?

You are probably stucked because you upgraded to the latest bootloader:
After updating bootloader to U5/S5 (as in case of G95xFXXU5DSFB) it will not be possible to downgrade it again to any U2/S2/U3/S3/U4/S4 version

Here's a workaround:
Backup your present baseband on TWRP, flash ALEXNDR Oreo's ROM then restore your baseband, otherwise you won't have mobile signal and your IMEI will be unknown.

So in theory the only way to downgrade to Oreo or less, is having the bootloader unlocked with TWRP right? if not, you're stuck

No Bootloader downgrade. Not possible.

Why would you want to downgrade anyways?

I can't speak for the OP but for me it is more battery friendly, has better perfomance, allow me to debloat more apps than PIE and has better mod/theme support and looks better (didn't like Pie UI).

Quick question for you @nemesisexsp as you seem to know what you're talking about.
I'm in the same boat as OP. attached is my SOFTWARE INFORMATION section with my baseband and whatever. Slightly different to what you've posted on your screenshot.
Can you suggest which files I should use from the ALEXANDR Oreo Mod selection? also, just the ROM, or do i need to do something with the BL files also?
I'm rooted (with TWRP), so that shouldn't be any issue.

I suggest you flash the last Oreo ROM available for the S8 model (SM-G950F/FD). After you flash it you can boot normally in the ROM and see if your mobile signal is fine, if it isn't just restore your PIE baseband on TWRP.
Here's the original post in _alexndr thread where you can find the ROM link:

Thanks for the quick response.
I made backups via TWRP just incase, but it looks like everything worked. [see image]
Thank you
It's also got me thinking...
-could you install other custom roms that are Oreo-based?
-What makes Alexndr's rom special?
-Is it technically possible to install stock oreo?

I think you can install other ROMs. I just suggested _alexndr because it's as close to stock as possible as the OP was trying to flash via Odin. But i believe that we can't install older firmware via Odin due to the updated bootloader.

Yes, many thanks.
I was trying to get as stock as possible but only found a NOTE8-to-S8 rom and nothing else stock-y. This seems perfect.

Because Pie is absolute trash on the S8 Active. Battery life went way down hill, constantly stutters like the CPU is loaded or it is thermal throttling, notification screen blanks preventing you from see any in the bar. Tapping notification doesn't always open. They ruined the camera UI. Control via bluetooth doesn't work anymore(forget the name but used to when I started my car it would automatically open Pandora and play. Instead now I have to unlock the phone and open Pandora manually".
I only wouldn't be surprised if it come out later that Samsung pulled and able and deliberately crippled devices to encourage upgrades. Joke's on them because my upgrade will be a different brand.

Unfortunately the S8 Active did not come in an exynos version AFAIK.

@nemesisexsp wondering, have you noticed much battery diff between Oreo and Pie?

[Early Warning] DO NOT TAKE OTAs after upgrading to Lollipop

If you've upgraded to the new Lollipop 5.0.1 update (N910VVRU1BOAF) for Verizon Samsung Galaxy Note 4 (N910V):
MAKE SURE YOU NEVER TAKE ANY OTA
unless/until
IT IS CONFIRMED THAT IT IS SAFE TO UPGRADE/DOWNGRADE
or
A dev has made a SAFE UPGRADE via Odin or recovery-flashable .ZIP​
One of the main advantages of this update is that you can use ODIN to go back to KK 4.4.4 at anytime, since the bootloader isn't incremented.
For Retail Edition: This is very important if you want to gain ROOT access when available & keep it over OTAs then.
For Developer Edition: Some of you have taken the OTA & restored his aboot backup via Odin. This was fine ONLY for this update. However, if the bootloader is incremented with any coming OTA, it'll block your unlocked bootloader for good & you'll end up with a Retail Edition. Moreover, if you were able to restore your aboot over an incremented bootloader using ADB/dd/etc utilizing ROOT access, you'll most likely HARD BRICK your device since the other critical partitions (TZ, SBL, ... etc) can break boot sequence due to failure in signature verification or version check.
Do we know if the updates will automatically install after a period of time?
I'm still on 4.4.4 NJ5, and the dialog pops up periodically. I am running without using the "no OTA" script at the moment. Has anyone experienced the phone update by itself after a while?
^^^I'm not sure, but I've been postponing mine since the Ota was pushed.

It's recommended to disable the OTA & manually update whenever you wish, if it's safe.
When blocking/disabling packages, which is the one that stops OTA. I've used the debloat tool for lollipop but just want to ensure that I've blocked it since I don't see any packages titled specifically as "OTA"

Know where I can grab the 5.01 firmware? I've already debloated / disabled OTA's, etc.
Also, I'm going to want to flash it through Odin, right? I'm on the retail edition (N910V)
Much Appreciated

For Retail Edition, follow instructions here to flash N910VVRU1BOAF_FullFirmware.tar.md5.7z!
So if if I upgraded to Lollipop can I still downgrade back to Kit Kat?

I did last night, just use Odin to flash the NJ5 firmware, when it tries to boot the first time it will bootloop. Pull the battery, replace the battery and boot to recovery (vol up+home+power) then wipe data. The phone will boot to the setup wizard for KK.
I'm a bit confused about this thread. What would the next update lock that isn't already locked? As I understand, the hope of rooting now is looking quite dim.
Not sure I care much since the SD card limitation has been addressed. That was the only reason I rooted my last phone.

From what I understand, its been confirmed that you can downgrade back to KK from 5.01. However, any updates thereafter (esp. OTA's through your carrier) have the potential to take away that ability to downgrade. A good example of this is the situation that happend with Verizon's Galaxy S4. The Update after MDK locked both the bootloader and the ability to downgrade back to MDK. No one was able to figure out how to downgrade back to MDK and only those fortunate enough not to have taken the update after mdk could flash custom roms that weren't touchwiz based (ie aosp). Since we don't know what the future holds for root on this device, its wise to keep all of your avenues open.

Another example, some Note 3 users fall into the trap of 4.4.4 OTA update & with no option to downgrade, they lost root, custom TW ROMs, and almost everything. Now, they're waiting with Note 4 users for a root method to rejoin the party while Note 3 on 4.4.2 can be rooted using TowelRoot.
Which tool?

All of the debloat tools that I find require root, which are you using?
There's a script that someone wrote to disable Ota and debloat. It doesn't need root. Sacher around on here for it
So would it be a bad idea to update just using the software update in the phones settings menu? Or should I do it by running odin? What actual difference does this make? Will this cause me issues once we do have a root method for this device?
As of now it makes no difference.
Stupid question, but how do you turn off automatic OTA on lollipop?

You could make a full backup of 6.0 then update to 6.0.1 and see how it goes. I for one am still on 6.0 because I am affected by the LTE issue.
Go for the update. If you notice any of the problems downgrade. Its quite strange but not all users are effected.

I'm having no issues with 6.0.1 at all. It depends on your personal usage and you should try it yourself. With a backup there is no problem to return to 6.0 if you should spot issues. Personally I would definitely update, just because of the security updates...

You don't need to be rooted, unlock the bootloader and create a backup using TWRP. The tutorial for this can be found in the general section of the Nexus6P forum .

Android Pay is not affected by unlocking the bootloader (or using systemless root). But unlocking will cause your phone to be wiped, so you should save important data manually.
The QFuse is not affected by unlocking the bootloader either, but it is popped by default during the fabrication process. There once was a thread about this somewhere here.

TWRP Lolipop Backup Recovery File to a Marshmallow Updated SATV

Can I flash my lolipop twrp backup recovery file to my updated Marshmallow SATV via twrp to bring back may previous setup before I upgrade may SATV to marshmallow without any problem?

Did you try to flash back a backup recovery file? For what I've read from here and other forums you can't turn back to previous fw(lolipop) from a marshmallow update... For that I hesitate to upgrade my SATV to the marshmallow
No you can't is the short answer, I tried and failed
I believe the Marshmallow update re-sizes the partitions and that's causing the problems.

The main difference for me is the adaptive storage but I've just bought a USB 3.0 HDD and I'm fairly happy with it, lots of storage and it's not really causing any lag like my SD card did. I have noticed a couple of crashes in the last few weeks which never happened on lollipop but it's nothing that a reboot didn't solve and they're not constant.
If an app doesn't work then that's the biggest issue. If the developer is good then it'll get updated (hopefully) but it's a real pain if you use an app and all of a sudden you can't use it. Only you can make that call if you know an app won't work yet.
The other thing I'd say is if you're happy with the device as it is and don't need any of the features marshmallow brings (let's be honest, doze etc is pointless as the shield is plugged in) then leave it. If it isn't broke don't fix it
I was able to downgrade back to the 2.1 firmware from 3.2. I posted my steps in the 2.1 firmware thread.

Nova Plus MLA.....

Is it possible, to open a thread for the Nova Plus MLA-LXX only?
Root, firmwareupdates , etc.
i think its a good idea...im in canada /rogers with mla-l03...and not much here for our version
Not rooted ( yet ) but got the unlock code, me too
have the code, yet not used, all my other mobiles ihave rooted
Like i said...our device is a one pretty young...birth in september so...theres no rush to "enter the dragon" :angel:
But very anxious to try nouEmui
i have tried the unlock code, and it works, but i have relocked it.....
I've the MLA-L11 too. would be awsome to have a working TWRP , no use in getting bt unlocked
unless there is a custom recovery. I'd say we find a dev and donate enough to persuade him to work
on a twrp !

You can try this to update to Nougat: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G79/g0/v73849/f1/full/update.zip Extract all the files and place them in a dload folder then place that on the root of your SD Card and install it using the three button method. If your Build Number is not showing up correctly after installing that install this: http://update.hicloud.com:8180/TDS/...-L11_hw_eu/update_data_full_MLA-L11_hw_eu.zip using the same method as before. If it does not work the first time you may need to flash the stock EMUI 5 Nougat recovery which will let you install Nougat updates, I had to do this for the CAN-L01C432 variant as the update kept stopping at around 40%. EMUI 5 Nougat Recovery: https://drive.google.com/open?id=0B4T1GJ6EZ3LvTWNpZ0p5YXVINGs It is up to you to try it and I am not trying to make you as I do not have a MLA variant so I do not know if it will work or not. I hope this this helps.

If it doesn`t work how to get back to notmal firmware?
I have all my devices rooted , but this one not, there are to less informations about my build, therefore i have no twrp installed.
Im careful, my last device was honor 7, and i have no problem with twrp and root, but more informations.
Download is very slow.
Do you have made the update to nougat, and does it run without bugs?

Lineage OS H815

Hello,
I recently noticed that the LG H815 build has been removed as a download because of an encryption issue, and I was wondering if, other than this, there were any other issues causing it to be taken down (I'm thinking of building it unofficially)
Thanks

Ok thanks. Is this the only major bug (I'm new to android development so I probably won't be able to fix many bugs)

There is an unofficial LOS build already. That's what I meant to say.
Yes encryption is the issue why we do not have official ones but encryption is fixed on aoscp by our genius kessaras. Ask in kobtuls LOS thread what the state in LOS is.

Thanks again. Just out of interest, how would AOSCP compare to LOS (it's one I have only just heard of)

I have just noticed it says you need v29a firmware. If I download it from cypheros.co, does it still need v29a (I'm on v20g and would rather keep it so I can roll back to stock using a TWRP backup if I need to)

You just need a V29a modem and bootloader package if you have a H815 handset, and you can actually flash that in TWRP as there is a flashable ZIP for that. I went straight from OEM Lollipop to AOSCP Oreo without issues.

Thanks. Just out of interest, why is this required (I thought the rom rewrote this anyway)

I assume this is mainly due to performance reasons and compatibility with newer custom firmware, but I do not know the full, technical story as to why that is the case. You're better off asking @kessaras and @steadfasterX for the answers

as far as i know if you have h815 that unlocks with .bin key from LG its bootloader its unlockable and it has antirollback 0 unless you have h815t or h815p thats locked bootloader and cant rollback i think
ask in thread and tell them if you have official unlocked boorloadre from LG. if you can roll back if you flash v29.

Thanks for the replies. Does Lineage OS also need this or is it only AOSCP

I assume any Nougat or Oreo, or PQRSTUVWXYZ ROM needs the latest available OEM bootloader/modem package, but don't act on this information unless you have asked around and those on this forum give the same answers.

Ok. Just out of interest, if I did flash a ROM that required a different bootloader and modem to the version I have, would it brick my phone or would it just not work properly

You CAN use an outdated modem partition. But you may encounter issues like camera crash, bad or no sound on voice calls, gps probs and / or sensor issues.
And depending on several things it's possible that it JUST WORKS FINE. I have tested even a LP modem partition with oreo (just a short test a while ago) and all was working here but issues can happen rarely.
A brick is possible but it will be a soft brick only which means the download mode is still there and you can flash a kdz to recover if needed. It either bootloops or a demigod bluescreen will happen on boot.

Thanks for confirming this. I want to keep as much of my phone stock as possible so it is easy to revert back to full stock if anything happens (this is my first proper venture into custom ROMs).
Also, is there any way to tell which version the rom requires by looking at the install files
