Well we don't want other countries csc since our network settings are usually different. Like the carrier aggregation combination list
[Samsung Galaxy Note 8 Questions and Answers] wow1996:
My Korean Note FE can use ATT's 4G perfectly. Even better than my N950F. I don't think there's too much difference in network. Because of N950f's f***** OEM lock, I am using N950U1, I think if Exynos model cannot flash other developers' rom. Snapdragon is better in daily life. (Especially in game play). I have OEM button when I open the box. Then, it never appear again after I flash other country's official rom
[Samsung Galaxy Note 8 Questions and Answers] white7561:
No. Carrier aggregation configurations are different between countries. That's why we need our own CSC.. say here they CA band 1,3,5 . But I use Australia csc that only use band 5,8,40 as a CA.. that means I won't be able to use the carrier aggregation here because of the Australia csc.. fyi : carrier aggregation is the thing for 4g+. Normal 4g is fine
[Samsung Galaxy Note 8 Questions and Answers] wow1996:
I got it.:good:
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Yeah :) that's why I rather use s8 csc for my country. I got oem unlock button with my 4g+[emoji28][emoji3][emoji16]
[Samsung Galaxy Note 8 Questions and Answers] wow1996:
How about using Korean's csc on N950F for opening OEM lock. Then flash developers' roms. In the end, flash our own csc. I am just a user, I know less about system~. I really want to open my OEM lock for unleashing my N950F. Especially its camera. Well, the experiment failed. I have tried it. so sad.
[Samsung Galaxy Note 8 Questions and Answers] sco00262:
can u add BRI csc pls, maybe it's my only hope to save me from my 7 days jail loop since i've bought Note8 for more than one month ago....
[Samsung Galaxy Note 8 Questions and Answers] xDreDz:
Thats it...

Tuesday night I got the OEM unlock so I toggled it and proceeded to flash TWRP and I got the " official binaries " thing. I lost hope. When I was about to sleep, I had this notification to update my phone, the security thing from sasmung and so I updated it. Wednesday morning,checked my phone and the OEM unlock is gone in dev options but OEM and FRP is turned off in download mode so I told my self to give it one more try. Plugged in my phone and I didnt expect anything till odin indicated that it was a PASS! And my phone turned off. I stood up, accidentallt hit my head and stub my toe then reached for the buttons to get to twrp. Aaaaand thats about it
[Samsung Galaxy Note 8 Questions and Answers] white7561:
No go. Because. I was using an s8 csc without any problems. But I stupidly flashed my country note 8 csc. And now I'm in jail. The first time in jail. An I've my phone for months...
[Samsung Galaxy Note 8 Questions and Answers] iigrs:
I got my phone with CSC code of MYM so I couldn’t get 4 G in my country. I haven’t been aware at that time on the OEM unlock issue so I flashed with Odin ILO firmware including that CSC. All went well but obviously I lost my OEM unlock. All that happened on November 27, today it’s December 10 and I still don’t have my OEM unlock back. In download mode I have both FRP and OEM unlock ON. Are there different jail times for different CSC ? Should I flash back MYM SCS and waiting another 7 days will give my OEM unlock back ?
[Samsung Galaxy Note 8 Questions and Answers] mahdibassam:
Ok just to recapt my story so far:

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.

SO, what confuses me and makes me scratch my head (among st other body parts) is the fact that when i flashed Renovate way back in September when i got my phone, i rebooted the phone like 10 times straight away to flash viper audio and dual speaker and etc, and it worked flawlessly, even when i restarted on the first day. But as soon as i flashed IronMan rom, the first restart got me into a boot loop and the binaries error.

1) Why didnt renovate have this issue?

2) When I get the OEM lunlock option back in 7 days, and flash IronMan again, would i get the same issue if i reboot?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
I already explained this like way back. I think it's because renovate uses s8 csc instead of ironman ROM which uses note 8 csc
[Samsung Galaxy Note 8 Questions and Answers] Techvir:
Wht Odin and what TWRP did u flash?
[Samsung Galaxy Note 8 Questions and Answers] mahdibassam:
So what's the solution to that? Would I just have to flash ironman and never ever restart? Lol
[Samsung Galaxy Note 8 Questions and Answers] white7561:
No lol. I've explained this like way way back lol. You should read first lol. I said you can install whatever ROM you want. But after that u need to flash tkkg s8 flashable csc mod on twrp. But since it's for the S8. U need to mod it to work on the note 8. He explained how in his thread. Then just flash and done lol
[Samsung Galaxy Note 8 Questions and Answers] Techvir:
Dont reboot for 7 days till oem unlock reappears
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Either you do that (and hope after 7 days it'll appear) or do my way. [emoji23]
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
Aside Renovate and Infinity Rom, have you tried your method on lightRom, Iron Rom and especially Ketan Rom?
[Samsung Galaxy Note 8 Questions and Answers] :
Last time flash the renovate rom,reboot no jail i tot already fixed the oem issue. After change to Ironman rom reboot straight go to jail damn angry. For now b4 update rom scary go to jail and make a backup.Very tired to repeat wait 7day oem appear. we pay the money but we still restricted by (them).No More samsung
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Ummm I'm using entirely another ROM. But it should work fine with every other rom out there. (Touchwiz/Samsung experience)

---------- Post added at 08:43 PM ---------- Previous post was at 08:41 PM ----------

That's why we need a workaround. I've already said this before to not use note 8 csc. If ROM doesn't give s8 csc. Install it yourself. This is my first time in jail because of my stupidity installing note 8 csc . And I've had this phone for months now
[Samsung Galaxy Note 8 Questions and Answers] xDreDz:
What else could I have used?

Mine appeared i think after 8 days.

n950f/ds from Singapore. And im using it in Philippines so no need for singapore sim.
[Samsung Galaxy Note 8 Questions and Answers] :
Today Follow ur method Flash s8 csc but at the s8 csc selection no my country code.
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Ye its fine. Use another csc for now. Like XSA or something. Just for now. just so you can use your phone with no problems

Am Still in Stock

I WAITED 7 DAYS STILL IN JAIL AND STILL OEM UNLOCKED IS MISSING

IS THIS BECAUSE OF THIS NEW UPDATE SAMSUNG RELEASED IN THE MONTH OF NOVEMBER

OEM UNLOCKED SHOULD Appear already this is strange

Has Anyone Had this Issue With the Update with OEM Not Coming Back After the Installation of this Firmware
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
Check CSC well, I also couldn't find mine initially, but saw it under DBT( that has many csc under it)

Am in jail for now for another reason, and would be trying Dr. Ketan method first and possibly the CSC approach too.

---------- Post added at 03:04 PM ---------- Previous post was at 03:00 PM ----------

You can reflash older stock firmware(one that came with phone), to see you would be lucky this time.
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
The S8 csc topic is interesting, since day one, i haven't had my device go into oem jail. Here's the kicker, i have only flashed things i have built myself, and ive only been using S8 features.xml in my csc.

My rom only has two csc options, which are DBT and TMO usa. Both have S8 features.xml so they can be modded. I had one user state he went into jail after flashing WETA, though somehow he had XEF as a csc, which isnt an option on my rom.

In my TMO usa csc, these files in the efs partition get changed to reflect TMO...

/efs/imei/mps_code.dat

/efs/imei/omcnw_code.dat

/efs/imei/replace_code.dat

Im wondering if the devices that have problems with jail, shoould be changing these files to a csc that should be totally open and not one of these countries that seem to be locking things up.

Just spitballing here... im not really that clued up on the whole situation as ive never been in oem jail to try and back out of it.

--->
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Could work. But here's the thing. The network configuration (volte , CA configuration,etc) will ONLY be applied. If all of em are having the same csc. Since if it isn't it'll not apply the configuration.. trust me. I've tried it before by accident [emoji28]
[Samsung Galaxy Note 8 Questions and Answers] kenpaci:
Awesome info..thats is logic
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
I have once modified these files multiple time for my own reason (Same like you we in India don't have this OEM mess so never experienced this)

but this shouldn't going to work bcoz I have remarked that these files get auto configured with detection of SIM and not according to files present in ROM.(yeah, earlier it was like that) So whatever you do, once you insert your SIM, it will change it to 1. Matching CSC of SIM if available in ROM otherwise 2.According system/omc/salescode.dat as default CSC Also modifying efs partition is not safe in hand of newbies.

Here is my experience with OEM, how it get affected with CSC and SIM card

so only I believe is current workaround is to use S8 csc to come out of this mess, though users are not much keen to report and share their experience, which makes more difficult
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Well tomorrow I should be able to get out of jail.. then I'll install s8 csc once again and proof all of em that s8 csc is the workaround
[Samsung Galaxy Note 8 Questions and Answers] wow1996:
Flash S8' s CSC with odin?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Nope. TWRP. I use [MENTION=5899304]Tkkg1994[/MENTION] s8 flashable csc .. modded with my newest country csc from an s8+ .. and I got my newest country csc for s8+ by downloading the multipart ROM and extracting the csc myself
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
Cool. Well, I'm going to stick with the s8 csc then. For the meantime I'm not seeing any particular drawback for using them.

Maybe in the furture, there will be some light shed on the subject if the Note 8 csc files ever get decrypted. I bet the answer is sitting in those encrypted files as a simple xml entry.

Edit.. and I suppose it's in the users best interest to have a flash no csc/omc option in rom huh.
[Samsung Galaxy Note 8 Questions and Answers] wow1996:
You already have OEM LOCK button?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Oh yeah. Regarding the encrypted note 8 csc. To be clear. The reason I got myself in this tricky situation is because. My country note 8 csc. ISNT encrypted. So I can just mod it all I want. That's the whole reason I try flashing it. Which made me stuck in jail. Also. I've heard from [MENTION=5899304]Tkkg1994[/MENTION] that only some csc on the note 8 are encrypted. But my other friends. Told me that it WAS encrypted when it was leaked. But it's unencrypted now .

---------- Post added at 11:11 PM ---------- Previous post was at 11:10 PM ----------

I've had it for months. From the first time I got my phone (after the first 7 days countdown thinggy) this is the first time I got into jail.. because I flashed note8 csc lol
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
Can you link me to that note 8 csc?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Which? My country csc?
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
Yeah anything that has the unencrypted csc files for note8
[Samsung Galaxy Note 8 Questions and Answers] wow1996:
So, there's still no way to let the oem lock appear immediately, right? I still have to wait for 7 days, even more?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Hmm. I've deleted the file.. since I don't use it anymore. Can't extract it since I don't have my computer nearby.. anyway. Why on earth would you want to try to use it? It has the oem unlock problem lol
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Full bunch of csc(78 countries) in OXM are all encrypted, not only in leak but in official firmware like QI9/Qk6 and now tested QK9 too. On the contrary, only few csc are un-encrypted
[Samsung Galaxy Note 8 Questions and Answers] white7561:
There's no way until you got yourself a recovery AFAIK
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Device won't get OEM issue if one using device from a country where no OEM issue exit and using SIM from same country. I tried plenty of CSC erlier on my device for some test purpose, even modified efs partition files too but never got this OEM issue
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Ah so [MENTION=5899304]Tkkg1994[/MENTION] is right .... Well . There's no use of it anyway. Since we will use s8 csc instead of the note 8 one.. also I've been comparing both files. Like the csc features XML etc. And I can't notice anything suspicious.. prob it's on some encrypted file somewhere inside the csc files
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
And what I'm about to say, is totally reckless and I don't recommend it,

But has anyone, who has found themselves jailed. Before flashing back to stock.. wiped out their omc/csc and dare I say it EFS partition? Removed sim card and tried rebooting with the modified system still in place? Maybe wiping all data also?

Again, this is reckless, and you are obviously relying on twrp to restore EFS correctly to not brick your device. But this is more to try and narrow down another direction to look other than s8 files.
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Yeh. Tho. Didn't you said someone who bought the device from your country has the problem when he was using a note 8 csc from problematic country?
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
I just want to get up to speed and maybe look through those files.

Maybe even purposely try to get into jail. For my own research.
[Samsung Galaxy Note 8 Questions and Answers] white7561:
You couldn't do anything if you're jailed. Since you can't even boot to twrp lol. And even if you successfully wiped efs. If it doesn't work. Then what? The device MIGHT not start the timer and the end results are the device can't connect using sim and you can't fix it since no root

---------- Post added at 11:23 PM ---------- Previous post was at 11:22 PM ----------

Hmm. It's up to you but. I recommend not doing it. Unless you are up for having a brick if something went wrong [emoji16]
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
Here's another thought. Has anyone tried slipping in another sim card from a different network while stuck in jail. Or is that what the jail seems to be there for?

---------- Post added at 10:24 AM ---------- Previous post was at 10:23 AM ----------

Ok, I just assumed you could boot into twrp but not system. I'm cheating and asking questions instead of searching, while rocking a baby to sleep
[Samsung Galaxy Note 8 Questions and Answers] white7561:
[emoji28][emoji3][emoji16].. anyway AFAIK we need to have the same csc for all of em (sim , csc , etc) to start the timer
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
All my questions may seem dumb and obvious, but thanks, I think I'm up to speed now.
[Samsung Galaxy Note 8 Questions and Answers] white7561:

[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Only after he inserted his country SIM where OEM issue is there and also it was not just after inserting SIM but when he got message, RESET device to applt new CSC - He opted to reset - that caused Factory reset - and OEM gone!!
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Hmm. Still tho. You could lose your oem unlock button if you try flashing the note 8 csc like for example for my country
[Samsung Galaxy Note 8 Questions and Answers] kilayo:
Aside from data. Will flashing 950n brick . It might be worth it just to get root and then flash custom Rom. And flash csc after. What you guys think
[Samsung Galaxy Note 8 Questions and Answers] white7561:
It could brick your phone. It could. We don't know tbh
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
Dr. Ketan, what if for now developers build Rom with limited CSC options from only country's without OEM unlock problem,

so that users later flash csc of choice if they can't use what Rom has (using CSC changer).

I think with that inserting SIM cards won't change anything.

Your view, please?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
I'll probably recommend developers to include some note 8 csc that has been confirmed working without any problems.. and the rest is s8 CSCs
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
That is how I made root for OEM issue and posted few pages back but no one confirmed it is working or not working.

If that works then strategy for developer should be - Give a 'OEM Patch' option in aroma, which install only S8 csc to keep OEM intact. with this users who don't have OEM issue can keep device up to date with N8 csc while OEM affected device will use only s8 csc, other than this, one more kind of patch I have included in my upcoming N6, but no tester, we can't do much.
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
Thanks for reply.

Am sure those of us who will give a try to what you posted are in jail.

Hopefully we will come back sooner to give it a try.
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
Here's another thought, probably already been addressed here, but wouldn't it be safer to flash roms and boot etc without the sim card inserted? Then once booted go in and check the oem unlock switch, then install sim?

---------- Post added at 11:10 AM ---------- Previous post was at 11:08 AM ----------

Fyi, I have a user, that has stated he has lost his oem unlock switch, though he is still rooted etc because he is scared to reboot. He is on about day 4-5 I think. Waiting for it to reappear. Would he help? He just posted in the WETA thread
[Samsung Galaxy Note 8 Questions and Answers] white7561:
1. Dunno if the timer would start without sin

2. If you put the sim after the button appears. It can get hidden again. I think it's better to put it after you flashed the S8 csc. Well if you can start timer without any sim

---------- Post added at 12:11 AM ---------- Previous post was at 12:10 AM ----------

I would suggest him not to reboot lol.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
If you want to help confirming our S8 csc, kindly ask your ROM users to flash file attached here immediately after flashing ROM, who have OEM issue.

This file simply denox + Root with Magisk + remove existing csc and install S8 omc

if this works then it will be confirmed, we just need S8 csc. Though conclusion almost saying this but we need confirmation. Also this will help devloper to make strategy for these users
[Samsung Galaxy Note 8 Questions and Answers] white7561:
He must flash it. After. He got the button again AFAIK . Since he can't reboot rn
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
That's what I always do on my Note 8 when am coming from recovery, but there are Roms that OEM won't appear and sometimes too the OEM toggle will be there, but vanishes after a change in kernel.

Whichever it is i setup then slap sim card into phone and if toggle is there or not.

I will reboot if I have toggle, but will have to wait for 7 days without reboot if OEM unlock is not showing.

I am still in jail.. I will give it a shot once I get out.. Not sure when though

Cannot falsh s8 csc in odin for those of us in the jail...

I have a device from UK ( no oem issue) to use in Canada but got into jail after a stock rom flash.. Tired using sim from UK ( in roaming mode ) for a week and even then could not get OEM back.. The issue I think is not the sim or the csc alone but the actual location of the device being reported back to samsung ( guess they use gps, network location and wifi location) .

I am currently testing something - Full stock flash, airplane mode with UK sim and internet connection via UK vpn through wifi only. So no exposure to canada location at all. Another 3 more days to go.

I am happy to try this out, if you can direct me... I do not know how to erase in an unrooted device..

Here is the link https://www.dropbox.com/s/gu3p11jlr...2_REV00_user_low_ship_MULTI_CERT.tar.md5?dl=0

I tried different sim's including local and from the country of origin... No go...

That reset option that comes up is mandatory... It has no cancel option. It will automatically apply the csc if you reboot.. I had gone through this a few times.

Hopefully me too...
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
I agree user should wait till OEM unlock toggle appears.

For me , I only flash Roms which OEM unlock toggle is not hidden by developer.
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Yep
[Samsung Galaxy Note 8 Questions and Answers] kilayo:
Yes 100%

I agree with you 1000% no oem on first boot out of the box. It has nothing to do with sim. It's your gps location i believe this. Because I've tested this. I never put my sim in on boot at first and i didn't connect to the internet. But my damn gps and nfc on boot is automatically on . And by the time i can disable it, it already pics up my location. And i still didn't sign into any account or data.. But still they know my location. So it is gps. Gps is always on on first boot.

So long story short - wait for OEM unlock to appear , once it does install recovery and flash rom (e.g. IronMan), and then stay in recovery and flash an S8 CSC, and then boot up. This should resolve the issue as far as we know so far?

Im in the 7day lockdown, day 3 of 7. will try as soon as ome unlock reappears.
