I flashed DX4.0 Infinity ROM and the OEM Unlock option appears immediately after System starts.

I tried reflashing 3 times and the OEM Unlock is there.

Can i flash it without rooting device?? Im in jail at the first place?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Gonna see if this uses s8 csc. I'll check later at home. I bet it is using it. That's why you got it after the system boots.
[Samsung Galaxy Note 8 Questions and Answers] Techvir:
Nope. You cannot flash this without root
[Samsung Galaxy Note 8 Questions and Answers] krabman:
Just to be clear, I have flashed every rom down below with Knox removed as well as several not on this forum and they all have OEM unlock available immediately after flash except for the two that have it hidden by their developer. In some of those cases I flashed them in their early versions before they ever did anything to the CSC and it was just the stock Note 8 CSC. One of them even changed the installed Note 8 CSC to a different (UK) stock Note 8 CSC and guess what, OEM unlock was immediately available after flash. This is not just my result, it's the result of many people who did exactly the same thing with exactly the same result.
[Samsung Galaxy Note 8 Questions and Answers] giusemc:
Could u please show me how to do it exactly please? Thank in advance :)
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Did you read Dr Ketan message? It might be because you installed some country note 8 csc that doesn't hide the oem unlock ! ... If you accidentally installed note8 csc for a country that hides it. It MIGHT remove the button like usual... That's why we asked them to try use s8 csc . As s8 csc doesn't have the oem button restrictions.. it's far more safe flashing s8 csc as the button will ALWAYS be there. (This is the theory. That we're testing) as for example. I have XID csc. The note 8 csc of XID have those oem button issues. While the S8 one doesn't. So I'll choose to install the S8 csc to be safe so I don't have to deal with those problems.... If you want to use note 8 csc, just make sure that it is coming from a country that DOESNT HAVE PROBLEMS WITH OEM BUTTON. But it's safer to use the S8 csc as it doesn't have any problems on the note
[Samsung Galaxy Note 8 Questions and Answers] vivi:
FYI

I did not have OEM Unlock option in first use.

After 7 days of using my Note8 it appeared.

I flashed Dr.Ketan ROM and Installed Dr.Ketan ROM Mode utility. It rebooted to dead lock.

I flashed official ROM and waited for another 7 days after that I flashed DX3.0 Infinity. No OEM Unlock option seen.

I waited for 7 days without rebooting it until it appeared again.

This time I falshed DX4.0 Infinity and after booting to system OEM Unlock option appeared immediately.

I reflashed DX4.0 Infinity ROM 4 times till now and every time OEM Unlock option is there.
[Samsung Galaxy Note 8 Questions and Answers] Tropo850:
Just wait the 7 days, get ur toggle. I flashed nemesis rom, xposed and running perfect no problems at all. I prefer to get a stock or close to stock custom rom.

Has anyone rooted there stock untouched firmware successfully yet?
[Samsung Galaxy Note 8 Questions and Answers] krabman:
After you get OEM unlock and install a rom you're going to have OEM unlock immediately on every rom. It's always been that way for everyone. I installed my first rom on a malasian Note 8 CSC, it was not changed in the flash because the rom had no CSC modifications and I had OEM unlock immediately after boot. I've also got it immediately when using the Singapore CSC, both hide the OEM unlock. In fact the Singapore CSC was my devices native CSC and I was on it for a few weeks while I installed most of the early roms available here back when they were in their first iterations and in some cases (as I already said) they did not have any CSC modifications at all. I later moved to the UK firmware because it has less bloat to deal with than most of the rest. Lots of guys installed roms without CSC mods in the early days on their stock Note 8 CSCs from regions hiding OEM unlock and they all had OEM unlock available immediately after the rom flash.

It isn't that I don't get what you're saying, I get it. The evidence doesn't support your conclusions very well and if that was the end of the story a whole bunch of rom installs would have never happened.

Thanks for zip will add my own csc files to it taken from system folder after flashing [MENTION=5899304]Tkkg1994[/MENTION] s8 csc selection zip. It actually changed the csc folder to something other the the system/OMC file structure but worked normally from what I can gather i had all the features I expected from my CSC plus the added options from aroma that developer added. So ill stay stock and flash your zip with my contents to system folder of your zip.

I'm in Jail till Sunday so can't report for a few days but will update when I can ?

I'm inclined to think csc flashing to get back to own country csc will screw with oem because I flashed lasted version of ironman Rom and it didn't include my country csc at all then flashed a note 8 csc twrp zip and it was gone yet every other time I had flashed s8 csc zip by same dev it worked fine. Anyway I'm going to wing it and hope for the best. I have nothing to lose and anything I learn from it can only prove useful. I also just remembered flashing my own home csc tar file through flashfire when using another custom domain Rom at the beginning of this whole nonsense and it broke oem unlock too so changing csc definitely breaks oem unlock when your using note 8 variant. I could understand if it was an Odin flash why it could be almost guaranteed but through flash fire I think that says it's not just the phone talking to Odin? Just my thoughts anyway lol
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Yeah say whatever you want. The only way to solve this is by trying it. We'll see who's right or wrong after peeps have tried our way and reported back.
[Samsung Galaxy Note 8 Questions and Answers] krabman:
Yeah, most def, flashing any csc after the rom install is bad juju, lots of guys have gone down in flames doing it. Just flashing a stock CSC alone will of course reset the timer, doesn't matter how, odin, mediafire, whatever. First reported way back. We have a couple UK F owners that have reported in as loosing their OEM unlock after installing their own stock CSC. That one is a real brain buster but it isn't just one, it's several reports. I flashed iron rom with the s8 csc and went into my first binaries since this thing started more than a month. That doesn't really mean anything because people have gotten away with flashing things others failed at simply by changing flashing procedures. As am exa,[;e when I reported that result another fellow said he had done the exact same thing but it worked out fine. Most likely however we didn't do the exact same thing, the difference may be my procedure versus his, possibly some combination of other things flashed in aroma and so on. There is more where that came from, I installed WETA 2.1 successfully after my experiment on Ironman and then decided I'd try and install it with a modded s8 tmo csc and guess what, binaries. Then again I've installed several of the roms with their modded CSCs without issue. Each one of those things is simply one result though and there are a whole bunch of variables.

@ white7561 I'm reporting actual results from across many flashers, known stuff, got nothing to do with being right or wrong. I'm too old to actually care about being right anyways and like everyone else would love to see an end to this BS. I would love for it to be right here and now. Whatever my opinions part of your idea doesn't hold water when compared with real world data but that doesn't mean that the concept doesn't have merit. This was why I encouraged another poster to try it out not too many posts ago. I'm all for trying things out and reporting the results, been saying as much on this thead over and over. More, I've put my money where my mouth is and been the first to try a number of ideas. An example, the first time ketan had a file to flash I was the one flashing it and I reported my results. I was there the second time too, this is the third time, cred to him for keeping at it. This time I'm not in a position to flash it but if I could, I would. Make more sense to you?

It's been a long journey and there have been a whole bunch of moments where everyone thought we had a contender just to watch it go down in flames. One of these times someone is going to get it right, maybe this time. Maybe not.
[Samsung Galaxy Note 8 Questions and Answers] Geekser:
can anyone verify if this is happening on the Single Sim Devices - N950F ? Or is it only happening on the Dual Sim Devices for those of us that don't have the right "sim" card possibly?
[Samsung Galaxy Note 8 Questions and Answers] Brava27:
Only F/DS devices from Singapore apparently.

---------- Post added at 05:30 PM ---------- Previous post was at 05:25 PM ----------

No OEM unlock for me. N950F/DS from Singapore
[Samsung Galaxy Note 8 Questions and Answers] Geekser:
Is that for sure ? No one with a - N950F has this issue?

Better question - does anyone with a N950F in the US have the ability to see OEM Unlock????

Up to this point - EBAY has only been selling the N950F/SD phone - but starting tomorrow - some sellers will ahve the single Sim N950F - I am thinking about buying one - but I wanted to find out if anyone using the single sim model has had this problem too?????
[Samsung Galaxy Note 8 Questions and Answers] $-MONARCH-$:
To make OEM Unlock available, It seems you need a Singaporean sim card, The XSP in the third section means they're carrier-bound specifically made for Singaporean mobile carriers. Once it's triggered by Singaporean Sim, you can see OEM unlock option under Developer Options.

---------- Post added at 05:52 PM ---------- Previous post was at 05:49 PM ----------

Have you flashed with Portuguese ROM, CSC XEF is a Portuguese ROM?
[Samsung Galaxy Note 8 Questions and Answers] Geekser:
I just checked Phone INFO and I can see that the CSC country listed on my device is Singapore. Does this mean that I buy a different device from a different country I will not have this problem?
[Samsung Galaxy Note 8 Questions and Answers] $-MONARCH-$:
Flashing ROMs from different regions wouldn't actually make a difference. Obviously, you will need to fly to Singapore and buy a Sim if you insist to use Singaporean set. As far I do not have an answer to your question why Samsung would do this. As your phone is bounded to the carrier, My best guess the Singaporean sets are quite cheap due to rebates offered by Samsung, more people buy from Singapore and sell them overseas which could result in restriction of using certain features.

So far I know Samsung restricted the use of OEM unlock outside the territory. Meaning it can only be triggered by Singaporean sim card and then you can switch back to your country sim.
[Samsung Galaxy Note 8 Questions and Answers] krabman:
Can you list the sources of this information? Exactly how many people can you reference that had the phone somewhere else with no OEM unlock option that fixed it by inserting one of the in country carrier sims? This isn't a call out but it I'm not seeing where you are deriving this from, I can find no corroborating data.
[Samsung Galaxy Note 8 Questions and Answers] mlkemac:
So who want to sell a Singapore SIM card? Lol
[Samsung Galaxy Note 8 Questions and Answers] $-MONARCH-$:
This is from a chat with the seller who sold me the device, the seller tells me that OEM unlock option is available for him since he is using Singapore sim card. I'm certain this carrier restriction. I went to Samsung's Service Center today, Which I told earlier in this forum that I'll provide with an update, Samsung is unable to help me unless I return the phone back to seller and get a refund to buy Note 8 from my origin country (It's not available yet in origin country).
[Samsung Galaxy Note 8 Questions and Answers] xxx42069:
I can't give you proof but I can concur that I have seen a similar trend. I know a guy a guy that bought from a different country. As a part of the purchase, his seller opens the phone, puts in a sim for that country to activate it, then sends it out. He got his and has oem unlock.
[Samsung Galaxy Note 8 Questions and Answers] $-MONARCH-$:
It depends if you buy Netherlands set, you get the option OEM unlocked, But it seems Singapore set was made only work with Singaporean carriers that's why you get the XSP code in the third section of CSC. Obviously, Samsung made a certain change to restrict the carrier-bounded device to be sold outside the Singapore, meaning you won't able to use all features unless it's used by Singaporean sim card. But I think the whole issue is only affected with Singapore set, while other sets such as from UK, India and The Netherlands appears to work fine with other sims cards.

Yes, You will not have this problem if you bought it from Samsung retailer, not through the mobile carrier.
[Samsung Galaxy Note 8 Questions and Answers] xxx42069:
Same here. Don't worry it's actually a huge relief. My old one is on its way back for a refund, new one with confirmed oem unlock is on its way to me. Now I can not check this thread every ten minutes.
[Samsung Galaxy Note 8 Questions and Answers] $-MONARCH-$:
Exactly, This what I have been told by my seller. At the moment I do not have any option, Only to get a refund from the seller or get the phone activated with Singaporean sim card.

---------- Post added at 07:12 PM ---------- Previous post was at 07:08 PM ----------

You actually can't just get Singaporean sim and activate it, You will need an actual working sim card and you have to be within Singapore or have your Singaporean sim card with international Roaming activated.

---------- Post added at 07:41 PM ---------- Previous post was at 07:12 PM ----------

To those who are asking me how it works only for Singapore, Read this kid from Singapore and apparently, he has Singaporean sim card and that's said being used to activate the phone which will trigger CSC XSP to unlock all available options to the user which lifts all restrictions imposed by Samsung for Singaporean set.

Obviously, y'all have an option, either return to seller and ask for a refund or ask the seller to activate the phone using Singaporean sim card and send it back to you.

This is only the option you can have OEM unlock, Flashing ROMs aren't gonna to help you anymore sorry.
[Samsung Galaxy Note 8 Questions and Answers] Geekser:
Thank you very much. I am pissed - but at the same time, relieved. At least I have an option - something I wasn't convinced of when I first discovered my problem. I can return (will return) the phone and buy a new one. I beleive I can get the Seller to work with me on this because he advertised the phone at a N950F and never told me it was dual sim. I would not have bought it had I known it was dual sim honestly - not that there is any real difference - I just wouldn't have.

so - hopefully he will work with me - if not he will accept the return and I will buy a new one from some one else.

The only think I have wasted is my time and sanity - I hate not having control - not being able to flash - well, it sucks. so moving forward - big lesson learned.
[Samsung Galaxy Note 8 Questions and Answers] xxx42069:
Did you buy from eBay? If so, you could be in luck. If the item was listed as just f but you received an f/ds, eBay money back guarantee has you covered. You can mark the item as not what was listed. You technically received a different item than what was in the listing. When this is done, the return and refund are guaranteed, all restocking fees are waived, and eBay will even force the seller to pay your return shipping costs!

[Samsung Galaxy Note 8 Questions and Answers] ARNOB:
Worst case scenario, do you think we might me able to achieve a temp root to toggle the OEM lock through adb and then unlock the bootloader?

I've ordered mine from Swiftronics N950FD Model and I suspect it might be a Singapore variant! :(
[Samsung Galaxy Note 8 Questions and Answers] Brava27:
I asked them this morning to turn on the device and see if it had oem unlock. Nope. Nothing there. I ordered a Taiwanese version and hopefully it has it.
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Well then. If we have the same goal. Which is to get a workaround. Then why does it feels like you're trying to prove me wrong about the theory?? You've said it yourself, a little different procedure can affect the result.. why can't you agree for me telling them to try my way? Well. I've already said this before... I'm letting you guys know my experience with it. And it seems like that it's fine on s8 csc , but when it's on note 8 csc. It just resets the timer etc... that's why I said to try it like I do. Well just to let you guys know. Before i post this theory. I was thinking of not telling you guys because I was lazy etc. But then I'm thinking. Well if this works on others this could be very good and helpful.. So then I post it..

Let's just wait for others to try flash S8 csc on their note phone. And see if the results are the same as mine. If it is the same. That means we've found ourselves a workaround
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
One more thing,

If you have OEM unlock option visible and you flash ROM dirty (without any wipe), OEM unlock should remain intact. This has been reported on my thread by two users and again this favors, something related to CSC. As dirty flash won't change CSC. [MENTION=1230317]krabman[/MENTION] N8 CSC also work for example after 7 days it gets appeared on N8 CSC too right? So it is possible that something in modus flashing ROM, CSC doesn't getting changed and OEM sticks. Also my experienced shared if you have read it, Indian version of device multiple time booted here as well in foreign country where OEM issue exist and no issue even on foreign SIM but get stuck as soon as factory reset option selected. So we need to collect more data and may soon we can reach to a definite conclusion so users have not to go to jail multiple times at least.

I don't have any issue related to OEM so unfortunately I can't test myself otherwise it may better help.
[Samsung Galaxy Note 8 Questions and Answers] vivi:

But I flashed DX4.0 Infinity with full wipe.

Wiped cache, data, system and internal storage and the OEM Unlock option appears with the uptime starts from 0 hour again.

Ok Doc,what Indian CSC you say works,my phone is XSA but I'm willing to download and try and see what happens.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
I don't know about csc used on this ROM. There are multiple ROMs reported having no issue and as far as i know some of them are having either S8 csc or included only CSC that doesn't have such OEM issue.

We need more reports if flashing any ROM + Flashing s8csc with root that I have provided y'day make OEM visible then we can conclude something positive.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
No there is no separate indian CSC available. If you flash multi CSC and that can mess, better try this

No it won't work that way

Indian firmware available is Multi CSC and on first boot it will apply CSC according your SIM and not stick to INS unless you are using Indian SIM in India

Thank you for all these explanations.

Two small questions:

1 / So I have my carrier_id which is BRI because my phone comes from UK England ?

2 / If I reset my phone and insert a SIM card from UK for the first activation, do you think it is possible for the Unlock OEM option to be visible?

[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Still I have doubt about this. Basically there are no difference in any country specific ROM which is multi CSC. Indian ROM is also multi CSC. Indeed it won't apply indian CSC unless you put an indian SIM, otherwise it may apply default csc which is probable XEF OR May be it get info from your EFS about existing CSC if it doesn't find active network connection.

My telephone was bought from Uzbekistan. After 7 days later OEM switch appeared and I flashed your Rom (N4). The ROM installed the original csc (CAC) by default. So, the phone started with cyril alphabet and by mistake I rebooted the phone. I was in bootloop. I flashed the stock rom to relieve. Naturally I lost the OEM switch. When I checked the software information the csc was TUR/TUR/CAC (as I used my Turkish sim).After 7 days, OEM switch did not appear. Then, I flashed the multi csc stock rom (OXM) and I used an Ukrainian sim to set up. After, I replaced it with my Turkish sim. Now I have TUR/SEK/CAC csc. The OEM switch is still missing. I will wait to see if it will appear or not (Although I don't have any idea if Ukrainian csc has any OEM problem). Next Wednesday 7 days expires. I will report the result.
