Update to oreo or root first? - Samsung Galaxy S8 Questions and Answers

950FD is coming tomw!
Eventually want Oreo and to root the phone.
Can't find any advice about which to do first.
I thought to get Oreo first but I've read there is an issue with 7 day OEM lock that Samsung added since the note 8.
Any pros and cons that you can share?
Many thx

The UK 950FD that arrived yesterday for me has OEM unlock available. With the usual dire warnings if you enable it, knox and security issues etc.

Update to oreo then root. If you root first you will lose root when you update

Upgrading to oreo O when it's released while rooted

Will I have to wait for a developer to build an oreo room and get the bugs ironed out? (No, I cannot build it myself) or is there any chance that there will be an easy way to upgrade to oreo and keep root access intact?
It will take a Dev to port it. Taking the upgrade, if available, will erase root and custom recovery.
That said, a Dev can take the system.img and other partitions and and edit them to port it to this phone.
When I had a note 4 there were ports to the note 5, S6, S7 and note 7, Lollipop, Marshmallow, Nougat . There may even be one now for the S8.
Don't hold your breath.
Bottom line: You need to be rooted and someone needs to build a custom rom based on Oreo.
V20 is expected to get Oreo in the first quarter of 2018:

Hopefully some devs will be around to root it, or provide a path from rooted machines to update without losing root.

YES!! (Hopefully) I have an unlocked AT&T version (not on AT&T) and I haven't got ANY updates, I ordered a AT&T GoPhone SIM, hopefully when I pop it in, I will get the updates

UK Fingerprint rom question

If i install the UK fingerprint version here . Will the update still come to my phone? I see they have new updates now and oreo 8 is coming. Will i be able to install those from within the device or will i run into issues?
Also are there any issues using the UK rom over the US rom?
Also are there any better ways to enable the fingerprint sensor without install the UK version?
Does it also void warranty?
Thanks!
I'm in the US & I installed the UK ROM you link to above. It works as advertised. I wondered about receiving the update as well and read through the entire thread. It says you will be able to receive updates and you won't void your warranty since you are flashing official firmware. Of course that is just a post on an internet forum and carries no weight. Other than the warranty does it really matter? You can always update using Flashtool.
Yesterday I updated to 8.0 following this thread https://forum.xda-developers.com/x-compact/how-to/stock-8-0-root-recovery-t3747479 and now I have 8.0, my bootloader is unlocked, I have root, adaway, my phone passes safetynet, and most importantly it still works..
There are some subtle differences between N & O that have made it worthwhile. Sorry I can't be of more help, I can only share my positive experience.

if you unlocked your bootloader, while you might be if there is an update, you can't just download and apply it from phone. If you're only interested in major android upgrade, this won't be a problem as at most we probably will only got one more android major version update (or none, it will be close to two years after device release).
If you are interested on monthly security update though, this could be a pain to flash manually each month
So if i just install the UK via the xperia flash tool method here (https://forum.xda-developers.com/x-compact/how-to/fingerprint-reader-version-flash-t3470154) , will i get OTA updates for security patches? Or do i have to manually do it every time?

Yes, you will receive updates as long as you do not tamper with the bootloader or recovery. If for some reason it doesn't work you can always use flashtool to apply an update. The convenience of the fingerprint reader working far outweighs the inconvenience of having to update a phone with a computer.

Galaxy S8 950U downgrade from oreo 8.0 to nougat 7.0

I would like to downgrade my galaxy s8 (G950U) sprint version from Oreo 8.0 back to Nougat 7.0 but I’ve been having a hard time figuring out if it’s possible.
Looking around I’ve seen people saying that’s it’s not possible due to the bootloader which doesn’t allow you to go down from v2 back to v1.
It’s also my understanding that the fifth number from the right is the bootloader version, in this case I have version two (G950USQU2CRC5). Now, looking at the Nougat releases for the phone, the last three that were released before Oreo show that they have the version two bootloader (G950USQS2BRB1, G950USQS2BQL1, G950USQU2BQK5).
So, would it be possible to downgrade if I used one of these three versions or are there other things preventing this that don’t involve the bootloader?
Thanks.
Yes. As long as the bootloader version of the package and the bootloader version on your phone are the same, you're fine.
Also, don't flash a bootloader 3 package unless you want to completely ditch Nougat or don't want root for a long time.

No OEM Unlock button after latest Pie Update 10/01/2019

I have a Verizon Samsung S8 SM-G950U. I want to root it to get a Pixel-like rom. I am new to rooting and am trying to follow step by step directions. I cannot get the OEM Unlock button to show in Developer Options. I have seen the people that say to revert the date backwards, but this does not work. I also do not have the option for " Manually Update". What do I have to do to get past this step? Thank you.

The U/U1 models ( US Snapdragon ) don't have the ability to have the OEM ( bootloader ) unlocked. The ability to root is limited as well as custom ROMs.
Updates on pie in software update now has download and install ( tap to check for update ). If update is available you then have the option to install now or later.
I have a S8 T-mobile S892U using Pie and bootloader ver5. Do It have a abiliti to show OEM unlock or downgrade OS or root ?
I jusst want to root it. I'm trying for 4 days to root it but I coundn't
Sorry for my English.

Keep v2 bootloader or upgrade to v3?

Right now I am on AT&T firmware CTA2 which is the v2 bootloader. I know if I take the OTA (I have it frozen so it doesn't auto update) to the March security patch it will update my bootloader to v3 and block my ability to revert back to Android 9. I am asking is anyone else in the same boat here and if so what did you? Keep v2 or jump to v3?
Anyone? Guess I am alone here on this one.
I upgraded to 10 before rooting mine, luckily the Binary code was still v3 aka build number G975FXXS"3"ASJG, so reverted to pie and rooted it.
Reason,as samsung are making it harder to root and i wasn't risking upgrading it.
Also no reason too, as custom roms will be made which will be 10, so best of both worlds

So what I am getting here is that you were on v3 bootloader and went back to Pie?
Yes, Look at the binary code, you will see number 3 in my build number.
there is a few more updates in pie, and also i think the first two in 10 that have binary code 3 in build number.
As i did update to 10 BUT only to the last update which contained the number 3 as i show in build number.
Thererfore i was able to revert back.
If i went further to binary code 4, then i'd be screwed
the last v3 you can use which is on android 10 and you can revert back if you wish is:-
2020-01-06 10 G975FXXS3BSL4 G975FOXM3BSKO
the next android 10 update v4 is:- 2020-02-12 10 G975FXXU4BTA8 G975FOXM4BTB1 (Do not update this, if you want to revert back to pie)
these are updates for my BTU G975f

Hey sorry for the real late reply, I just now dug up this thread. I noticed you have G975F phone. Is it rooted? I have a G975U phone. Does this matter? If I update to bootloader v3 (which is the bootloader my carrier is on), I can go back to Pie as long as I don't update to bootloader v4?
Reports in the forum here are saying once you've updated to a newer bootloader version you can't go back for the G975U version of the phone.

I did have the G975f which i did root successfully, sold it on and replaced it with the A71. which is much cheaper, a cracking phone, and has snapdragon chip which are much faster than exynos.
Midrange phones are now coming up to the main flagship phones, and cameras are excellent on it, and its also rooted.
Anyhow.........
Anyway if your s10 has the Exynos chip, you can root, if it has Snapdragon, as far as i know its not possible, you'd need to search.
As i mentioned in post, if the binary code aka 3 remains and it does in the early 10 release, then you can of course go back to pie, as i did.
If you upgrade to binary code 4 aka BL 4, you can not downgrade back to v3.
I'm not sure if it is still rootable at v4, you'd have to check, as like i say, i don't have mine anymore and never got to that stage to investigate.
Hope that helps you bud

So v3 can go back to v2 bootloader? I have a snapdragon G975U phone running AT&T firmware so I can't root it. I just don't wanna brick my phone if I unfreeze the update and update to v3 then wanna go back to v2 bootloader later.
