Means now we can't use base from any region which have oem issue? Though need to interpret more with multiple report, what was there in OTA that caused this.

When available to download then I will check and compare with previous k6 of BRI so we may get some idea if find some different code

[Samsung Galaxy Note 8 Questions and Answers] sefrcoko:
If I'm using an Exynos N950FD (Singtel CSC), should I use my carrier's S8 CSC here in Canada (BMC / Bell Mobility) even though that's a Snapdragon device, or instead flash Singtel's S8 CSC? Just received my new Note 8 and thought I had figured everything out before taking the plunge, but this seems to be the last point I'm not quite clear on yet.
[Samsung Galaxy Note 8 Questions and Answers] statikk1:
Hi all

Some feedback regarding this oem crap

Australian XSA non-carrier (bought outright) Exynos Note8 here

Been to Jail once and have had OEM come back weeks ago but did nothing until the S8 csc idea started coming in.

Just updated to Qk9 firmware first.

Flashed TWRP and upon entering TWRP swiped to allow changes.

Formatted Data "yes" and immediately rebooted to recovery

flashed magisk 14.5 (latest build) and s8_csc_for_oem_issue_XSA.zip one right after the other.

Rebooted and hoped for the best.

Phone booted up. Upon going to settings the "Developer Options" quickly disappeared off screen.

Upon activating Developer mode again, it was a big relief to see the OEM toggle there and still ON!

I've since rebooted and gone in and out of recovery multiple times, restoring crap using titanium-backup etc. and everything is fine.

Result is pure stock rom that is rooted and OEM sticks.

Once small issue that I've so far noticed and it's probably because of the S8 csc, is that I'm missing a toggle for "Wifi Calling" but within Wifi settings it can still be enabled.

Hope this helps those who want to have stock rom and root ;)
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Thanks for reporting, now at least we have relief that we have at least one method to keep oem option enabled. Also to note that, flashing csc file I have posted also deknox your device so you won't have security alert post root. I will add some stuff later so stock rooted user can use Samsung health and some other minor patch.

Once device have oem unlock option available and enabled in dev settings, you can reboot any times you want, just refrain from flashing any csc stuff.
[Samsung Galaxy Note 8 Questions and Answers] Androidwizzard:
[MENTION=3931450]dr.ketan[/MENTION] oem toggle appeared again after around 6 hours on that BRI I've reported so that's definitely a relief :cool: but strange anyway

Thanks for the zip Doc, ?

In jail again until tomorrow night I think or early hours following morning and need XSA CSC too which I already grabbed from your link will report mine soon as a can. ?

I knew it deknoxed I read the updater script ?
[Samsung Galaxy Note 8 Questions and Answers] ShanerZa:
I just want to confirm, if I flash your CSC zip, does it just run the script or does it open a windows to select a CSC?

Hi [MENTION=3931450]dr.ketan[/MENTION] could you please add XFV to the current flashable CSC?

Thank you in advance.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
You have to flash a file that includes your CSC, it won't give any option while flashing. I will add XFV tomorrow.

Anyone tried Dr Ketans s8 csc on ironMan Rom?
[Samsung Galaxy Note 8 Questions and Answers] BasketCase7:
no unlocking oem after the flash of Minotaurus Rom v8 and s8_csc_for_oem_issue _ OXM. zip

my n950f itv purchased with oem unlock present in the developer options, after a flash of a firmware via odin, I had to wait 168 hours to make the button appear again, flash twrp, custom rom and csc s8, no unlocking oem present at the first start.

[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Csc is S8 (G955*) in screenshot

Ironman mod setting have oem hidden may be user have choose moded

Or may be flashed rom without sim may retain older csc

No. I meant. Look at the product code. There should be a csc code like on the last line.

I have downloaded QKG and have noticed a new line in build.prop

ro.build.version.security_index=1

I instinctively set it to "0" before I tested it as a rom. And I still have my oem switch

[Samsung Galaxy Note 8 Questions and Answers] Negroid:
So it's been 7 days and oem unlock toggle has finally appeared.. The only issue is it is greyed out and unselectable (screenshot attached). Ideas?

(When I got this device I wasn't able to see developer options by pressing build number, I was only able to access the setting by downloading an app short cut for it via the play store [screenshot attached] and on initial launch it said developer options are disabled. But then second launch it worked. Providing this info in hopes that it will help diagnose the issue).

Sim card is currently not in so I'll put it in and try again.
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Can you try changing it to 1 and test it while using S8 csc? It might help us to see if it's for the thing or not

---------- Post added at 02:40 PM ---------- Previous post was at 02:39 PM ----------

No. U can flash ANY ROM you want with the button still available (if they didn't hide it intentionally) . U just need to flash the S8 csc after flashing ROM. And when you reboot it should be there like magic
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
If I remember correctly People have reported recently here are Infinity,reno and my latest N6 In case of my ROM N6, you need to select 'OEM Patch' option while flashing ROM, no any extra csc you required

Though with csc patch other ROM should work too

Reno and Iron ROM with modded setting have hidden OEM
[Samsung Galaxy Note 8 Questions and Answers] ShanerZa:
Thanks a mill! Silly question, I like the normal Samsung Touchwiz and UI. Is that possible in your rom or is it all themed?
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
I prefer stock UI only, TW is not modded at all, SystemUI is completely stock UI unless you change with Rom control, that also won't change UI but some extra option like hidden button,speed meter etc. I gave up themming stuff since samsung added own theme store

[Samsung Galaxy Note 8 Questions and Answers] ucevik:
OEM switch is still missing although many 7 days passed. When I checked the software information the csc is now TUR/TUR/CAC. As the reason has appeared to be csc related, I wonder if anybody has OEM switch available with a csc that has not the same triplets (for example insead of TUR/TUR/TUR etc.)?

[MENTION=3931450]dr.ketan[/MENTION] So i just flashed twrp and ironman rom, and straight away flashed your CSC for S8 (XSA) , however oem unlock has now disappeared from settings, and i am scared to reboot :D
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
XSA was reproted working. Have you selected stock Settings while flashing ROM? Bcoz Iron rom moded setting have it hidden
[Samsung Galaxy Note 8 Questions and Answers] white7561:
I can confirm before using XID, I was using XSA and it works just fine
[Samsung Galaxy Note 8 Questions and Answers] mahdibassam:
Well ****, I might have chosen modded lol. So now i cant reboot for 7 days right?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
No. You should be able to do it afaik
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
When OEM lock is invisible we can just guess only, theoretical there shouldn't be issue as you have flashed safe CSC

But remember, you have choose moded settings so your OEM will never going to appear, even after 7 days. Only you have to take chance anytime, now or after 7 days.
[Samsung Galaxy Note 8 Questions and Answers] chloeleedow:

[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
I will yes.

Edit.. I've set it back to "1" and rebooted, nothing prevented my boot and oem switch is still present. I'll do some more testing today to see if I can figure out what it does but may not be related
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Edit to my previous msg above :

If you dare to reboot, let me know once. I can give kind of try which may make OEM visible if it is there without reboot but no guarantee it will work, if that fail then you have to reboot.
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
Another observation of mine, I mentioned editing some files in efs to match csc version being used. It was stated that these files get changed back or changed to the sim being used when booted? I have edited between DBT and TMB a few times now and it sticks, doesn't change on boot. But possibly this does depend on what carrier sim you are inserting, my TMobile sim may be expecting something else in a snapdragon efs, and simply fails to do anything to efs. This may also explain why I have never been in oem jail. Has there been any reports of TMobile USA users being in oem jail?

---------- Post added at 07:46 AM ---------- Previous post was at 07:40 AM ----------

I don't know what I've done right, or not done to allow me to constantly flash 3-4 times a day, kernel and rom, for 3 months but if I can help by providing any files or info let me know.

Here is my basic info, I have not updated bootloader or modem since owning the device. This is a habit of mine since having the LG V20. They surprised everyone with anti rollback, and updating modem of all things could trigger it.

So cac is the region that's locked in at. I'm in the same boat. Need a sim from that region. I think I'll give up. Sell my note 8 and buy one from a seller that opened it and activate oem already then when i get it. I won't even turn it on. Just straight to download mode and root

[Samsung Galaxy Note 8 Questions and Answers] ucevik:
I don't think CAC has OEM issue. I bought my telephone from Uzbekistan. It had a sticker on the box saying that it should be initialized with a native sim card before using it with another country's sim. I used a sim from that country first. Then, came to Turkey and used a Turkish sim. After 7 days later OEM switch appeared and I flashed Dr. Ketan's Rom. 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. Now, It is still missing although 7 days well expired.

Just got out of jail about an hour ago, flashed twrp in odin then flashed ironman rom with modded settings and immediately after [MENTION=3931450]dr.ketan[/MENTION] s8_csc_for_oem_issue_***.zip OXM csc. Everything fine, booted up and rebooted just to see if it worked and nope... back to jail :(

So just a warning for everyone who wants to do the same as me.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
This is the third report that oxm csc still causing issue even if you use s8 csc, so probably issue could be specific csc rather than s8/N8 csc

We need to work more on it.

So don't use oxm csc even if it is S8 csc

Just one more thing do you have flashed rom with sim inside or without sim?

Also can you tell which csc was applied after rom installation?
[Samsung Galaxy Note 8 Questions and Answers] bigpapa007:
I did flash with sim inside, after reboot it asked me to change to the correct csc I think, since mine is PGU from claro Guatemala, I said no.

The CSC installed was the German one.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
My suggestion to all oem issue device owner, better flash a s8 csc which are reported safe. If you don't have any network issue then keep using it else take chance to replace only cscnetwork xml only from your original csc (S8 csc) if any network issue there.

I will try to look if we find any line which may causing issue in oxm csc
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Wait need some info

You have flashed iron rom immediately after flashing twrp or you have reboot in between?

I still don't get, if you have clean installed then how come it ask to change csc after clean installing rom.

I believe, there was left over of your old csc that might created issue
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Also one possibility, installing foreign csc, Samsung consider it modified and may have blocked it

Better you have requested your own csc if one not available on my post. PGU is not available on oxm
[Samsung Galaxy Note 8 Questions and Answers] bigpapa007:
Which csc's are reported safe? Just to know or maybe post a list of safe csc so far.

Yup, flashed it immediately after flashing rom and before flashing rom I did a format data and advanced wipe of everything 5 times.

I think Ive read that n8 reads the sim csc and if it detects it is from another region it asks you if you want the correct one.

I did asked you to add the PGU csc a couple of days before but maybe you didn't see it, so since it wasn't added I just used the oxm.

2. format the device with twrp

2. immediately install [MENTION=3931450]dr.ketan[/MENTION] s8_csc_for_oem_issue_XID.zip

Mine its exactly the same. I preorder it from Samsung Australia. It is supposed to be unbranded and unlocked. Also no OEM unlock option in developer settings?
[Samsung Galaxy Note 8 Questions and Answers] $-MONARCH-$:
Ridiculous, It's getting out of hand. Are you sure you bought it from Australian Samsung? I have never seen Samsung Store shipping out their units outside Australia. It's most likely you've purchased from third-party sellers and locked to region/carrier which might need Australian sim card activate all features including OEM Unlock.

I purchased an unbranded N950F from Clover (UK) and had them remove the region lock. I have the OEM unlock option.
[Samsung Galaxy Note 8 Questions and Answers] bober10113:
so this seems to confirm that the region lock = no oem unlock.

within 5 minutes of using a phone(phone calls?or data?) in the right region the unlock should dissipate as other users here have inadvertently confirmed by telling us the option just suddenly appeared.

although phones might not be locked to carriers the region lock might be in effect as other xda members have stated.

question is: is it possible to get the region unlock while not physically there? is there anyway to circumvent?

edit:

www.androidcentral.com/region-locking-galaxy-note-8-explained

my note 8 was sealed with a tamper proof sticker. im curious to know if by default People who received sealed boxes have this oem unlock issue as the phone never accumulated enought "air time" to get region unlocked.

also would simply placing a call to signapore for 5 minutes unlock it? i would doubt it but almost worth a try as described here:

www.techadvisor.co.uk/how-to/mobile-phone/how-remove-samsung-region-locking-3590401

"you can deactivate the region lock by first placing (or receiving) a five-minute call within one of the approved countries"
