Can't confirm on other Roms, but with Infinity and Renovate Rom i can testify and been confirmed by about 3 other friends that using Luca's S7/S8 CSC changer with amended script works well and OEM unlock always sticks.

Note that Infinity Rom comes with only one CSC, so to get your country's own, you need to change.

You can ask Luca.

Again am not comfortable with your stance sometimes when it comes to OEM unlock issues,

eg: someone advice N8 user to login to his Samsung / Google account and wait for 7 days. You have severally come out quickly to say, it's not necessary, that some haven't done so but OEM has appear. My beef in that is at this stage because we don't know what is the cause and to be sure all precautions are taken, that should be the best advice. Nothing wrong with that advice.

I hope you know that with the steps you initially posted, some of them are also not necessary, but better than not trying.

( African Proverb - Too much meat doesn't spoil the soup)?

On the current banter with regards to csc changing, why don't we encourage him and keep fingers crossed, than to openly debunk whatever he says, am just not comfortable with your stance.

A big thanks to Dr. Ketan for showing keen interest in finding solution to our problem.

Shalom.

CSC changer on infinity rom

I can confirmed that csc changer works on infinity and Reno rooms without oem problem.

Been use it since I was jailed after flashing iron rom.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
To work on CSC theory I have asked some users to check it on different ROM and confirm that ROMs which are reported no issue with OEM are all using S8 csc. For Infinity, I have got info that it does have very limited csc like India,Italy, malaysia,VN etc which doesn't have OEM issue

Consistently My and Luca's reported for disappearing OEM as we both have Note8 and multi CSC. So at presently more and more circumstances lead to say root cause of this issue in CSC only. Also my experience with Indian Note 8 on other country support this.

So let's we hope soon we may reach to a conclusion to end this OEM disappearing stuff, though first jail may not have solution.

I am keen to hear result of zip I have provided y'day with S8 csc.
[Samsung Galaxy Note 8 Questions and Answers] white7561:
1. Probably yeah

2. It could work. But it's gonna be either the button show immediately or you still need to wait a week

---------- Post added at 05:00 PM ---------- Previous post was at 04:59 PM ----------

Or. You could just do this. Only put ins csc on /system/csc . It should just use the ins without any hesitation since it's the only one available
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
thank you for your reply

If I put a SIM CARD UK for activation after reseting, should I leave the English card for a week? or just the time of activation?

I just have to get a SIM Card UK to test. :D
[Samsung Galaxy Note 8 Questions and Answers] white7561:
If you can just wait until the oem button appears. Tbh we don't really know why it happens. But I'm guessing if the csc is not a match with another kind of csc inside the phone, it'll not start the timer thingy
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
We were talking about odin flash and when someone in jail we have no such option otherwise I may have provide d already. Any things modified will fail in Odin if you don't have oem unlock
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Ah. I thought you guys were talking about on twrp etc
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Thank you for this information. So the way to go according to you is:

1 / I reset my phone

2 / I insert the SIM card UK for activation

3 / I leave the SIM Card UK inserted for 07 days if OEM is not visible during the first activation.

This is correct?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
If you can. You could try putting the sim first. And then flashing stock BRI ROM. And then go reset. If phone info shows all BRI . Then fingerscrossed it'll show the button in a week
[Samsung Galaxy Note 8 Questions and Answers] krabman:
As to logging in to Samsung, lots and lots of people have not done it and got OEM unlock. It's come up over and over and over and over and been tested over and over and over by people from everywhere and shown not to matter over and over and over. At no point did I say not to, I said it doesn't matter which is fully supported by the data we have. Not something I said to start with because we didn't have the benefit of time passing and people trying various things. In fact when it was first mentioned I logged into Samsung the next time I picked up my phone because I hadn't been but anything is worth trying when you have no information. Course that was in the beginning. Now with the benefit of time and the experience of many we know we don't have to and I took my own advice when I finally went back to jail a bit over a week ago and didn't log in to Samsung but still got my OEM unlock just like everyone else that has already done the same. This is different than when we first came up with flashing procedures because we had no data. There was absolutely nothing we could look at and know whether something mattered or not because no one had tested anything.

The former part of your post, I never disagreed with trying I disagreed with a conclusion that was drawn that doesn't hold up to the factual evidence in hand. Trying on the other hand, different story. Anything is worth a try until it's proved out for better or worse and I have already encouraged a guy to do just what he said not too long ago on this same thread. They are two separate things. I'm sorry if I'm not making myself clear on it. Coming up with an idea and trying=good. Drawing conclusions without consistent data that contradicts known data= not good. We've been stubbing our toes on the latter over and over here. It may be I'm getting too damn wound up trying not to let that happen?

[MENTION=3931450]dr.ketan[/MENTION] Totally agree, everything points to the CSC as being an integral part of this mess. Something I keep meaning to tell you and the commentary here recently reminded me... I still have as a system app the config.apk you first sent me back at the start. The thing has survived through a ton of rom flashes and a number of CSC changes. I never restore google data and cant restore my Ti backup but it's there right now just as it's always been. Don't know if that means anything or not in the grand scheme but it seemed odd enough to bring up.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
What??

Really interesting..

That app is showing as system app or data app? And can you confirm the location of that app?

And have you not restored with Samsung acc too?

Really weird that why app doesn't get wiped. Have you ever tried to uninstall manually? If possible please inbox me that app
[Samsung Galaxy Note 8 Questions and Answers] krabman:
System. I've never been able to find it, doesn't show up in a search with root explorer or at least it didn't when I last decided to go look for it. I've never used anything but my Ti backups which doesn't (shouldn't?) pick it up because I only back up user apps I have looked in the archive before I reinstall apps and it dosn't show. Still, it's been here all along. If you recall directly after I tried flashing those apk's I must have done a half dozen stock firmware installations while trying the different reset strategies. A couple of those were full, AP, CP, BL, and both home CSC and CSC. Did the same just now with the UK firmware which I installed for this round. Between here and there most of my rom installations were formats rather than wipes. Once we figured out you don't have to format every time I started skipping it but there were probably somewhere towards 20 formats between now and when I installed that APK. Somehow the thing is surviving.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Didn't get it. Where exactly it showing? app drawer? or in Titanium? any screenshot will be helpful
[Samsung Galaxy Note 8 Questions and Answers] krabman:
It is not in the app drawer, its a system app and can be seen in the main settings/apps. It can be disabled but not uninstalled. If I go to look for it in Ti backup it shows as system as well but can be neither frozen nor uninstalled.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
If you are talking about this app shown in ss then forget it, it's Samsung stock app and remain there in every rom, has nothing to do with app I provided.
[Samsung Galaxy Note 8 Questions and Answers] puddingoz:
Achieved nothing,looks like the default csc is in the flash memory,factory reset applys the default but no problem getting to homescreen without data.
[Samsung Galaxy Note 8 Questions and Answers] krabman:
Thats probably it then, would explain how it stayed alive through all that. It shows 1013 in my settings, I'm in jail so I cant look at it in Ti.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
yes, without SIM it will apply stock. May be you have XEF as this is default even on INS ROM.

it's just version of app, so nothing more to research. I was surprised as not possible to survive after a simple wipe + flashing a ROM.
[Samsung Galaxy Note 8 Questions and Answers] kenpaci:
For me its showing 1004 version
[Samsung Galaxy Note 8 Questions and Answers] Tropo850:
Hey. I'm using Nemesis ROM. If i flash the lastest firmware update with flashfire. Will it be alright and boot back up with oem toggle unlocked. Or will i lose oem unlock toggle and be back in jail.
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
1 / So according to you in addition to inserting a UK SIM card it is necessary in addition that I flash a ROM stock BRI (Taiwan)?

2 / I can not stay with the current csc XEF stock ROM (France) and just insert the UK sim card?

3 / Bri being a Taiwanese CSC should not we instead insert a SIM card from this country rather than a UK SIM card (from where was sent note 8)?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Omg my bad. I thought BRI was UK .. wait. How did you get BRI when you bought your phone on UK? That means try installing the stock ROM BRI . Then reset your phone. See if on phone info all of em will change to BRI .

---------- Post added at 09:40 PM ---------- Previous post was at 09:39 PM ----------

@Zayatoshi no need UK sim or anything else for now. After you installed it. Give me phone info csc screenshot
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Ok I just hope I do not have a compatibility problem on French networks by switching to a BRI ROM.
[Samsung Galaxy Note 8 Questions and Answers] white7561:
You shouldn't be. If you really want to make sure you got all the compability you need. After you install twrp. And ROM. Flash S8 XEF csc from recovery after installing ROM. It'll have the same compability thing as XEF from note 8.

That's what I do with mine too. I install XID S8+ CSC to get all the compability I need
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
OK. I could flash the CSC Xef of S8 anyway via TWRP if the flash of ROM STOCK BRI made it possible to make appear my OEM
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Yep. This is just to get the button. If you have root u can install whatever csc you want .. remember use the S8 one to make sure you don't have those button problems again. We're still waiting on peeps to answer if the S8 csc thing helps. But on my case. It sure does ... Well. I'm on jail 1 right now because I flashed note 8 csc lol. Before this I was using S8 csc without any problems. I have reset my /data etc and first boot I have the button always. So ye that's why I conclude that the note 8 csc is the one causing it
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Okay I understand better.

2 questions before the flash:

1 / Currently I am with the latest stock version N950FXXSAAQK9.

Can I take the latest BRI version of 28/11/2017 N950FXXU1BQK6? No problem of compatibility according to you?

2 / What is the best handling? A mandatory reset before flashing the BRI stock ROM? or just a flash over the Xef?

I seem to have read that it was necessary to perform a reset, and an activation to start the counter of 07 days. Am I in the right?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Should be fine AFAIK to downgrade on Exynos .. and for reset. U can reset after the flash procedure.. AFAIK you don't need to login etc to make it start the counter. I think u only need to be connected to a WiFi or mobile data for internet. Let me know the csc screenshot after you've done all of em
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Ok so the reset is mandatory to start the counter procedure.

I flash tonight and I come back to you with my phoneinfo screens.

:)
[Samsung Galaxy Note 8 Questions and Answers] white7561:
I don't think the reset is mandatory to start the counter. I asked you to do reset to try change the csc :)
[Samsung Galaxy Note 8 Questions and Answers] chloeleedow:
I actually hate Samsung for this crud alone mate and I've

been loyal since 2011. I'm just a root and flash junkie I think that's why we're are all here hey. On the bright side I've met some great folks banding together to share knowledge here on this forum alone, just so frustrating as Rom support is growing and I'd flash weekly if updates were coming that fast i cant help myself but sammy has rained on my parade with this garbage haha.

[Samsung Galaxy Note 8 Questions and Answers] Tropo850:
If anyone is wanting to have a official stock rom with root. This method worked perfectly for me.

Flashed nemesis rom with notorious kernel. Installed all my apps that i needed. Installed flashfire. Selected to flash system, csc home and param. if csc fails. Flash in odin. Preserve recovery. Set to reboot in to recovery when finished. Flash csc changer, supersu. Then boot into download mode. Flash bootloader and modem. I had a few random bootloops when booting for first time. But was normal i guess. And done. Booted up. No loss of data. Fresh stock rom AQK9 with root and oem toggle still in dev options. Remove knox manually. No force closes, errors, running perfect.

[MENTION=6004670]Zayatoshi[/MENTION] I am in the same situtation as you.

Purchased Uk version of N950F. Had OEM out of box. Installed custom roms and other stuff and ran great for a few weeks.

I am using it with rogers in Canada. My csc changed to RWC/RWC/BTU as expected with rogers sim.

Then I was concerned about some signal issues ( it was my mistake..I only realized later that there were no signal issues ) and decided to flash stock UK rom to get default csc ( BTU/BTU/BTU ). When I did this I lost OEM unlock option.

Since then I have done a lot of testing.

1- Flash stock rom and insert local sim and wait for 7 days.. Used phone as usual including some reboots.. OEMdid not show up

2- Reflash UK Version of rom and inserted UK sim ( but it was in roaming mode as I am in canada) and wait for 7 days... No reboot till I was more than 8 days...... No OEM unlock

3- Currently I have factory reset , then on boot put phone in airplane mode, GPS off and then connected to wifi ( router is on VPN to UK ) . Then inserted UK sim but not connected to network.. I am trying to replicate as if I am in UK ..... I even created an UK samsung account via uk VPN ... Used this account to login to samsung.. .It only day 3... Will wait for 4 more days...

4-- if 3 does not work, then will use combination firmware to go back to pure UK factory rom and wait for 7 days ( I already did with but connected to network ) THis time I will just boot the phone after flashing and not connect to network.. IF this too does not work , then I have no idea what to do.. May be sell the phone and get another device..

PS: I have always logged into google and samsung account.

The issue we are facing seems to be unique to those devices that had OEM unlock out of box and then lost OEM.. There are quite a few users with this problem.

However, Most of the users in this thread did not have OEM unlock out of box but able to get it after 7 days..

I strongly belive that OEM unlock issue has something to do with CSC and also has a geographical significance .. ie why users in UK or India or some other countries with OEM unlock out of box not facing issues but when these devices are moved to a different country facing issues.. Someone please correct me if I am wrong in this assumption..

[Samsung Galaxy Note 8 Questions and Answers] PlutoDelic:
This thread is being shifted to the options of already having the advantages after one passes the OEM Unlocking procedures.

There are a lot of us who never have seen the OEM unlock show up, or somehow reverted to the Stock option of not showing back.

I hope i am not asking too much to create another thread that deals with the resistance of maintaining Custom recovery/Root and leave this thread what it is supposed to be. The OEM fiasco is still there.

I got my N950F (New Zealand Unbranded) Note 8 and waited the 7 days for OEM Unlock to show. I then immediately Flashed TWRP & Renovate Rom and it was going great with no Binary issues for over 2 months. I then decided to flash IronMan Rom. phone booted successfully after installation. Went through the whole phone setup etc. Installed all my apps back. I then rebooted the phone to flash Viper audio. Then the dreaded 'Only official released binaries are allowed to be flashed' message. I then had no other choice but to flash back to stock Rom with Odin and am now in the 7-day jail period.

I don't want to rely on the 7 day crap. I bought my phone in Canada but its region is Malaysia-csc is cho. At first i did my set up as usual and didn't see oem toggle. I check and i had frp and oem lock on-long story short i did a whole bunch of reboots etc. I odin uk firmware thinking that would give oem toggle-nope. At first i couldnt activate dev-options without setting up and putting my info in.. So i tried a new method try to get frp lock off- and i did this with frp tool. then putting in my stock firmware and creating a development enable tar file to flash in odin. odin the file the phone took it and rebooted. Factory reset and now i activate dev options without singing in or setting up. so the phone shouldnt know where i am. but still no oem toggle. So what if there is a method to enable development from odin and odin a way to activate the toggle.
