Wow, they really do have nerves at Samsung to do this..

Looks like it is not possible to flash an older Bootloader.

I dont want to write dirty, but imagine all words I do have in mind right now.

Looks that I do have the first un-rootable S9+ Exynos in the world...

The Bootloader to be flashed is

BL_G965FXXU1ARC5_CL13138380_QB17212853_REV01_user_low_ship.tar

No words.....:mad:
[Samsung Galaxy S9+ Questions & Answers] maik005:
That is since years. You can't flash an older binary version.

Flash the newest one with AP. BL, CP and CSC to to a factory reset as I told you.

Then there must be OEM unlock option after 7 days.
[Samsung Galaxy S9+ Questions & Answers] joe535:
Ok. Will try. But as far as I know there is not yet a newer version. Can I flash the same as already is in the phone?
[Samsung Galaxy S9+ Questions & Answers] maik005:
yes. The thing is to flash AP, BL, CP and CSC so all data is erased and hopfully OEM Unlock comes back
[Samsung Galaxy S9+ Questions & Answers] joe535:
Verified, I already running the most recent firmware. So I will just do a factory reset from the bootloader..

By the way, I didn't find anything here if after factory reset I directly have to enable developer options or even wait 7 days to do this..
[Samsung Galaxy S9+ Questions & Answers] gaww:
You are back to square 1 - 7 days. If you can unlock after then, it must likely tell you to do a factory reset - which will result in another 7 days - UNLESS when it tells it to, don't let it complete. Get into download mode (like pic above) and ODIN TWRP. Follow the guides from there and you should be home free.
[Samsung Galaxy S9+ Questions & Answers] joe535:
Yes. I have read that immediately boot into download mode :)

Now waiting 2nd time to 7 days..

Keep fingers crossed that it will appear oem...
[Samsung Galaxy S9+ Questions & Answers] gaww:
Good luck.
[Samsung Galaxy S9+ Questions & Answers] joe535:
Hi again. Now the 2nd waiting period is over. I still don't see the oem unlock option.

What I did :

New phone. Enable developer options. Wait 7 days. Full wipe factory reset from the boot menu. Enable developer options and wait 7 more days.

So there are definitely exynos variants in the market without oem unlock.

I was not lucky.. Samsung for me is dead and I will advise everyone no longer to support this brand...
[Samsung Galaxy S9+ Questions & Answers] maik005:
have you asked Samsung about that?
[Samsung Galaxy S9+ Questions & Answers] gaww:
If you go into Download Mode, what do the 2 lock items say ? Also, do you see prenormal?
[Samsung Galaxy S9+ Questions & Answers] joe535:
I did not contact to Samsung as I doubt they are willing to support me in this case. Since they dont want their phones to be rooted, why should they support me??

I attached a screenshot, as you can see it is still in Prenormal-state...

By the way, my model exactly is SM-G965FZBHXSP...

And I bought it from the UK. The vendor confirmed that this phone was from Hong Kong. So actually I would expect Snapdragon but he also confirmed (I asked before purchasing) that there is exynos inside. And in fact it seems to be, because "CPU-Z" shows exynos (9810) as well...
[Samsung Galaxy S9+ Questions & Answers] gaww:
Your locks are on also, so you are on square 1. Did you ever see OEM unlock in developer options at the very beginning?
[Samsung Galaxy S9+ Questions & Answers] rypz79:
It has to be registererd with Samsung's servers i.e

request an update (if you have the August patch already installed it won't update anything) and then the timer begins. Wait 168h, connect to internet (i'm not sure if you need again to ask again for an update) and only then you will have the OEM unlock option. Sadly I learned it the hard way.

The thing is I couldn't see any indicator of that timer/counter on my device I've looked for a sign of it in the bootlog inside the recovery mode and couldn't find anything that might suggest a counter. I think it's registered only on Samsung's servers.
[Samsung Galaxy S9+ Questions & Answers] joe535:
what do you mean by "It has to be registererd with Samsung's servers i.e" ??

Do I need a registration of the phone at Samsungs homepage? Doesn´t it work without?

So my phone transfers data to Samsung without my knowledge and permission, this is illegal.

since 3 days I can see that there is another update available. I am running the August-update because my phone

has been in repair, thanks to google, they locked my phone as I did a reset...

Should I run the October-patch update?
[Samsung Galaxy S9+ Questions & Answers] rypz79:
There is no October patch as far as I know and if there will be and you'll install it you'll be forced to do a factory reset which means re-registering with the RMM server which means waiting another 168h before OEM unlock is available.

There is no connection between registering your device at Samsung support/product/customer DB and registering it with Samsung's RMM (Remote Monitoring and Management) server(s).

This action is leagal because you accept all Samsung's EULA (you have to to use it's devices).
[Samsung Galaxy S9+ Questions & Answers] maik005:
October patch for the S9+ is out since yesterday (DBT)

S9 got the same patch today (also DBT)
[Samsung Galaxy S9+ Questions & Answers] rypz79:
I've now checked my SM-G965F/DS and I don't get it.

Maybe it's for some CSCs.

Anyhow I won't install it untill I'll root my device hopefully this Thursday.
[Samsung Galaxy S9+ Questions & Answers] maik005:
Do you have the SM-N960F (Note9) or the SM-G965F (S9+)

also atm it is only for the DBT CSC.
[Samsung Galaxy S9+ Questions & Answers] rypz79:
I wrote SM-G965F/DS i.e S9+ Exynos with dual-sim

I have a different CSC (ILO).
[Samsung Galaxy S9+ Questions & Answers] maik005:
yeah I saw what you wrote... but

SM-Nxxxx is the Note series...

SM-Gxxx is the Galaxy S series.

thats why I asked again.

Yes, ILO it is not out yet. ILO is still on BRGA Firmware.

But you can flash the BRJ3 OXM firmware manuelly with Odin if you want to
[Samsung Galaxy S9+ Questions & Answers] rypz79:
Yes my fault G not N of course. I using the SM-N9005 (Note 3) for now so it's creeped into my head I guess :silly:

I just want to get this root thing over with. other things don't matter at this moment. As you can see I'm not even going to use the device without rooting it.

Anyway I wish someone could address my question above about the bootlog and the RMM timer though I'm almost sure it's not written anywhere in the device to prevent obfuscation.
[Samsung Galaxy S9+ Questions & Answers] joe535:
Well, if it was legal, imagine: I do not accept the EULA. I cannot use the phone without. So every official sellers MUST accept if someone returns the phone because he is not willing to accept the EULA. The full price of purchase has to be refunded...

Now then, Registering with RMM is an automatic process that is triggered if I accept an official update, is this correct? So I would expect that, if I do NOW an update, that 7 days later I will see the OEM unlock ?!?!?!
[Samsung Galaxy S9+ Questions & Answers] rypz79:
Yap basically that's how things work.

As far as I understand you only need to ask for an update to get registered with the RMM server not accept or install it it's an automatic process.
[Samsung Galaxy S9+ Questions & Answers] joe535:
I found something in a thread of another page. Can THIS be true ??

"RMM State lock is enabled anytime you format or reboot your device. It also activates if you insert a SIM card that

doesn’t belong to the country

your device firmware is optimized for."

My phone is from China, using it in Germany...
[Samsung Galaxy S9+ Questions & Answers] rypz79:
Cut "format and reboot" paste "factory reset" ,now it's true.

However after you flash TWRP you can install a patch that blocks the RMM service in your device so that you won't have to deal with these issues anymore. It probably will also deny you from getting OTA updates but I guess that's a fair tradeoff.
[Samsung Galaxy S9+ Questions & Answers] joe535:
Not sure, I even cannot flash twrp if OEM unlock is not visible...

I chatted with the samsung support in Singapore (sorry - my phone is not from china)...

They confirmed that OEM unlock can only be activated in the country of device-orign with a SIM-card of same country..

I would have to spend 7 days in Singapore and will need a SIM card (hopefully prepaid will do)...

But what I dont understand, yesterday I was asked to update to G965FXXU2BRJ3 ..

I did with no problems, so how can it be a problem to be in a different country if updates do work??

So Samsung actually declares it to be illegal to buy a phone from a different country.. Very interesting strategy...
[Samsung Galaxy S9+ Questions & Answers] rypz79:
Of course you cannot flash TWRP because your bootloader is locked because you're RMM state is prenormal (OEM unlock state is off) TWRP~ROOT ?

About the CSC of origin I bought my device in the states and currently I'm in Israel as soon as I entered an Israeli carrier SIM it asked for factory reset 168h after that I got the OEM unlock without even the SIM being in the device.

What happened next (twice) is written in my previous posts in this thread I suggest you'd read if you don't want to fall on these pitfalls again.

Tomorrow I'll be smarter i.e I should get the OEM unlock switch.
[Samsung Galaxy S9+ Questions & Answers] joe535:
See, my phone did not ask for reset when I inserted the German sim card..

I just installed the newest firmware ota..

By the way, did you leave the phone connected to the provider network during these 168 hours?

I did not...
[Samsung Galaxy S9+ Questions & Answers] rypz79:
You don't need to, just "touch" Samsung update (Wi-Fi) get confirmed turn off the device and wait 168 hours.

I now got the OEM unlock switch I'll later flash TWRP , Magisk and the RMM patch.
[Samsung Galaxy S9+ Questions & Answers] joe535:
okay, additionally I did the Device-reset yesterday from the settings menu. Still in pronormal-state. As you said, I may switch off the phone

but I dont necessarily have to.

Last try... :)
[Samsung Galaxy S9+ Questions & Answers] rypz79:
Insert your current country SIM and it automatically should request for a factory reset otherwise you don't have an carrier/factory unlocked device i.e you can use any carrier SIM in any country which have a compatible cellular network https://www.gsmarena.com/samsung_galaxy_s9+-8967.php

[Samsung Galaxy S9+ Questions & Answers] joe535:
I bought it as carrier unlocked and in fact I am using it in 3 different countries. But I was not asked for a factory reset when I inserted my sim card... I did the reset manually and now am waiting for the 3rd time to 168h...

By the way, who does the unlock? Network provider or Samsung?
[Samsung Galaxy S9+ Questions & Answers] joe535:
I have bad news, just as expected..... I did the reset as you said. The 168h are just elapsed.

Now guess what...

Off course I don't see OEM unlock.

Great, I don't want to say that anybody here doesn't tell the truth, but I just got the proof that there is a lot more than just inserting a sim card, reset the phone and wait 168h...

Seems that Samsung support gave me a correct information. You must be in the country of origin with a sim of the same origin for at least 168h to get OEM unlock..
[Samsung Galaxy S9+ Questions & Answers] gaww:
I have a European origin S9+ in the US and had no issues starting from scratch.
[Samsung Galaxy S9+ Questions & Answers] joe535:
So my phone seems to have its own mind... :crying:

Did you wait 2x 7 days with a reset after 7 days?
[Samsung Galaxy S9+ Questions & Answers] gaww:
I did because when I selected OEM lock off I didn't go straight to download mode when the reset started. Had to wait another 7 for paranormal to go away.
[Samsung Galaxy S9+ Questions & Answers] joe535:
Okay, so it has been your own little "mistake" :)

At the end you were lucky.. I cannot - no matter what I try..
[Samsung Galaxy S9+ Questions & Answers] gaww:
That was at the very beginning and had not been tried, but can't figure out your situation.
[Samsung Galaxy S9+ Questions & Answers] joe535:
By the way, did you leave the phone connected to the network all the time? I don't. When I am at home, I deactivate network and use WiFi only..

OEM unlock problem after reset factory

Hi guys

A strange insider has come to me!

Before the full reset, the option OEM UNLOCK was active and then the complete restoration of this option, my fare disappeared completely!

I waited for 7 days and used all methods but it is not worth it ...

I've even flashed a few official rumors but it's useless.

It's been around for about two weeks, and this problem persists.

Thanks for helping friends if you have a solution:svetius::svetius:

I have never encountered such a problem in any of Samsung's models so far:rolleyes:
[Samsung Galaxy S9+ Questions & Answers] gaww:
Mine was on network most if the time. Doesn't matter either way.

---------- Post added at 02:24 PM ---------- Previous post was at 02:17 PM ----------

Got to download and see if the 2 licks are on or off. If off, don't worry about it. Then, is prenormal there? If so, and locks are off, stop messing with it and wait until prenormal goes away, and then Odin TWRP and go on from there after doing a lot of reading.
[Samsung Galaxy S9+ Questions & Answers] alex00006:
I can see FRP off in downloading mod

But in developer option miss OEM ?

After flash ROM Europe or Asian...

No change this Condition

If both locks are off, no problem. Is prenormal visable ?

Now Example I want install TWRP or I want normaly on OEM for security phone .....

what i do for fix problem and show option

Oem unlock in developer options??
[Samsung Galaxy S9+ Questions & Answers] jujubeans:
I thought flashing would trip again and you would have to wait another 168 hours.

if you get past 168 hours and OEM unlock still not there, try turning dev options off, then turn it on again.

I couldn't see OEM unlock after 168 hours, waited till about 170 hours, still couldn't see it - so i turned dev options off, then turned on again and OEM unlock appeared.
[Samsung Galaxy S9+ Questions & Answers] alex00006:
1 hour ago flash again stock Rom but I haven't again option OEM UNLOCK in Developer options:((((

what you mean change in developer options?
[Samsung Galaxy S9+ Questions & Answers] gaww:
Do you mean you ODIN'd stock ? If so you reset it and will have started the clock all over again.

You really need to do more reading and find a guide and not just floundering around.
[Samsung Galaxy S9+ Questions & Answers] jujubeans:
My understanding is that everytime you flash stock rom - you WILL reset clock and have to wait 7 days (168 hours) again.

Secondly, when you finally do get past those 7 days (168 hours) and don't see OEM unlock - Go to developer options, up the top it will have a toggle to turn developer options off. TURN DEVELOPER OPTIONS OFF, then go back into settings and press build number 7 times again (enabling developer options again) then look for OEM unlock.

It worked for me when i was 170+ hours with no OEM unlock - I simply disabled and enabled developer options and it appeared.

Do you think I is worth to manually flash the latest firmware by Odin? And then wait 2x7 days?
[Samsung Galaxy S9+ Questions & Answers] gaww:
Yes and if lucky might be only 7 days.
[Samsung Galaxy S9+ Questions & Answers] Eagle:
Did you had your SIM card inserted while waiting for the 7-day period to end? I've waited twice without the SIM card inserted and to no avail, the OEM unlock option is not in the Developer Options. This time, third tries in total, I have inserted the SIM and hoping that the OEM unlock would appear again after the trial ends. (SM-G965F S9+) Reason for it not inserted was I had a secondary device as my main.
[Samsung Galaxy S9+ Questions & Answers] jujubeans:
Yeah my SIM is always inserted. Never tried any other way so not sure if you need to or not.

I would assume you would need your SIM in with the 168 hours.

Is it possible that I must install a branded version before I will be able to see OEM unlock?
[Samsung Galaxy S9+ Questions & Answers] ChaosOyster:
Sorry for the lack of knowledge. I got a few questions

Does OEM unlcok void warranty?

What does OEM unlock specifically do?

Does it use the stock Samsung boot animation or the mobile operators one? For example I have a 3 mobile boot animation on my current S9 and would enabling this bring back the stock Samsung one?

I bought mine second hand, for like 500 bucks. there was no rmm thingy and oem unlock was already there. I failed my first twrp flash, but quickly let it shut off before boot. now I got rooted s9plus, wonderful.

[Samsung Galaxy S9+ Questions & Answers] maik005:
OK. Which active CSC and which Firmware version do you have?
[Samsung Galaxy S9+ Questions & Answers] Geekser:
Active CSC is XEU - I think the firmware (Bootloader) is: G965FXXU1ARC5
[Samsung Galaxy S9+ Questions & Answers] maik005:
OK. So it is the newest official firmware.

Maybe it was only a bug in the first (factory delivered) firmware?
[MENTION=2543940]Savoury[/MENTION] would you be so nice and test it again on one of your devices after installing full ARC5 Firmware package?
[Samsung Galaxy S9+ Questions & Answers] Geekser:
I ran the update after I did the OEM Switch - now that I think about it - I am 90% sure I rebooted immediately after I flipped the OEM Switch - but I might not have. I have rebooted several times since (and before I got the firmware update) ??

So I am curious - why is it supposed to do a factory reset? And did you say that an Error message of some kind shows up too when you do this?
[Samsung Galaxy S9+ Questions & Answers] maik005:
I personally haven't done it. But. Yes there comes an error message then. See attached file (in German)

Integrity check on boot fails. The phone checks the firmware. There might (have been?) a bug(?) where that check fails after rebooting when enabling OEM Unlock.

I am sure Samsung did not want it that way, because then they would have a big warning before enabling OEM Unlock.

Hopefully it is fixed in the first update for S9/S9+!
[Samsung Galaxy S9+ Questions & Answers] Geekser:
It sounds weird to me - if you have just flipped the OEM switch and not flashed anything - what integrity was broken ? Maybe a warning to say you are in risk because OEM was unlocked? But like you said - why not just show that when you flip the switch? And why force a factory reset? That happens on Nexus phones when you unlock the bootloader but that is completely different from flipping the OEM Switch - LIke I said - didn't happen at all to me - so maybe this is a bug with the firmware in your area? Good luck - hope you enjoy your S9
[Samsung Galaxy S9+ Questions & Answers] maik005:
[MENTION=8285038]Geekser[/MENTION]

That error was on first (factory) firmware.

After your response I think it was a bug which hopefully was fixed now with the first (day one) firmware update.

Let's wait for other responses.

With Samsung you only enable OEM Unlock. Then you could flash twrp and after that format data partition.

No need to unlock bootloader via Fastboot.

So if my RMM state is "Prenormal" I have to wait 7 days before I can flash TWRP? In download mode, I can see "OEM Lock: Off", so does this mean that ive already got the OEM unlock setting enabled? (had the integrity issue after first reboot)
[Samsung Galaxy S9+ Questions & Answers] Geekser:
thanks for the clarification - I noticed today that my signal strength is not as good (mobile data) as before on my previous phones - in fact I dropped calls four times today while talking with my wife (which created a whole new set of issues) Not sure why I am having dropped calls - never happened on my Note 8 or S8 Plus - the LTE Speeds are good - getting around 26mb download and 7mb up - but only 1 bar on signal strength meter and like I said, dropped calls four times today.
