[Samsung Galaxy Note 8 Questions and Answers] Byte_76:
I have the N950F imported. (Probably from Dubai)

The OEM unlock option was missing.

I used my local SIM in the phone for about 4 days and then I removed it and put the phone away for a while. Charged but unused. (OEM unlock still hidden)

After approximately 7 days from first power-on, the OEM unlock option appeared. (The phone still had no SIM card installed at the time)
[Samsung Galaxy Note 8 Questions and Answers] ucevik:
Are the 4 days with sim card in included in 7 days from first power-on?
[Samsung Galaxy Note 8 Questions and Answers] Byte_76:
Yes
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
Am sure the 4 days were included.

Same as my case, I bought in Dubai, setup with my roaming sim, then travel back home. Within the travel time the phone was off for 2 days, but on the 7th day OEM unlock toggle appeared.

Does anyone know for SURE that which model of note 8 could have oem out of the box(in USA) and support CDMA and GSM??
[Samsung Galaxy Note 8 Questions and Answers] Maxito1983:
I'm in jail again! ? ?

This is what I did!

1.- Restart in Download

2.-I installed TWRP with ODIN

3.- Then format "yes" and wipe

4.- I installed Ketam Rom with OEM patch marked

5.-Restart Recovery

6.-Finally I installed s8_csc_for_oem_issue_OXM.zip and rebooted system. Oem was there in Development Options and to make sure, I rebooted the system and until then I arrived ... Jail again ... ???

What did I do wrong?
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Did you enable the button ?
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
Yeah, am sure he didn't switch OEM toggle on.

So he will get FAP Lock.
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Yeah.

---------- Post added at 12:20 AM ---------- Previous post was at 12:20 AM ----------

Did you play with the button? Like enabling disabling etc?
[Samsung Galaxy Note 8 Questions and Answers] Maxito1983:
OEM was already activated when I started the system, but I did not play with it, turn it on and off, I just looked if it was there and nothing else
[Samsung Galaxy Note 8 Questions and Answers] white7561:
Weird.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
First of all, I said don't flash any csc after oem patch in installation guide unless serious network issue, you wouldn't have flashed csc if N6 was working fine.

Other than this there are multiple report saying flashing S8 oxm csc causing issue. I am thinking to remove it.
[Samsung Galaxy Note 8 Questions and Answers] Maxito1983:
So for the next one I would just have to install your rom activating the OEM patch and nothing else ?? :confused::rolleyes:
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
Exactly, if you have any network related issue, just post on thread otherwise just continue using rom with default csc of oem patch.
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Hi doc.

So for the first time the option of unlocking oem appeared on my note 8.

And this for the first time in more than a month.

What have I done?

07 days ago reset and I installed a ROM xef (I am in France).

And I've changed one thing compared to my previous reset... I inserted a SIM UK.

My phone has a bri carrier_id but was purchased in UK.

In short I read all pages of this topic.

However I don't never found myself in this situation.

What would you advise me as a solution to install twrp and root my note 8.

I read a little of everything and I'm lost.

Must it flash the csc of the s8? The csc multi Flash.?

Install your ROM?

Actually the solution to maintain visible oem option

[Samsung Galaxy Note 8 Questions and Answers] kanamor:
I have in the same situation, phe/phe/bri impossible activate oem unlock ???

I tried to do what dr ketam commented a little more back, but without result, I gave error in the installation by odin.
[Samsung Galaxy Note 8 Questions and Answers] Maxito1983:
Thanks doc!

Now I just have to wait for the six days that I have left!
[Samsung Galaxy Note 8 Questions and Answers] WizP:
7 days have gone past and no oem unlock.

Changed my csc to BTU through the Renovate app. This gave me BTU/BTU/XSP.. Then flashed Ironman which sent me to jail.

It was previously XSP/XSP/XSP when I got the phone and the OEM unlock appeared after 7 days.

This is certainly making for an interesting issue.

Any idea how to get back to XSP/XSP/XSP without the OEM unlock. Do I just flash the associated oem firmware? Anyone get out of jail with miss-match of csc?
[Samsung Galaxy Note 8 Questions and Answers] btyeh:
No issues so far from installing Dr.Ketan N6 ROM. I have installed Xposed 89 and a couple of modules, flashed files in TWRP and back (an issue I had before), and OEM still sticks.

The only "issue" is that upon bootup, I get a "Kernel is not seandroid enforcing" error on the top left, but it continues booting normally. No idea what it means as usually people who get this error get bootloops. Mine? Not so much it just continues on as normal.

And I did not have to install Magisk at all, it is included in Dr.Ketan's ROM.

p.s. The only problem now is making XPrivacy work on Xposed 89 and Nougat. It's the last app that I absolutely need on my phone before I formally switch over as my daily driver!

I think the process is still:

Stock firmware, wait 7 days for OEM Unlock to appear.

Then flash TWRP > Dr.Ketan ROM etc. back-to-back.

Ignore step 6 as Dr.Ketan stated. Just double-checking you did not flash TWRP without OEM Unlock? :rolleyes:
[Samsung Galaxy Note 8 Questions and Answers] Techvir:
TO go back to XSP/XSP/XSP you can use a combination firmware. There are a few posts earlier in this thread. You might have to search for it.

Also people have got OEM unlock with and without miss-match csc
[Samsung Galaxy Note 8 Questions and Answers] Elin28:
Silly question : I used to have OEM button when I flashed infinity Rom 4.0 and past weekend I flashed infinity 5.0 but surprisingly the OEM disappeared. I didn't do the full reboot but did a hot reboot... It doesn't send me to jail. My question is does that mean I am safe to do a full reboot!? Or hot reboot is something different..
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
Hot reboot only restarts Android system. I wouldn't do a full reboot if I was you. A full reboot would reboot to kernel
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
Don't reboot, developer says there was an error in dx5.0 which sents people to jail on reboot.

He has released an updated version which you can download but you have to wait until the OEM unlock toggle appear.
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Hi

To have OEM displayed, I made a complete reset, and I put a foreign SIM card (UK at home), to show the OEM options a week later.

Now, it is true that I have not yet installed TWRP or other for fear of losing OEM visibility, because I am a little lost with all the options and possibility of flash:

- Multi Flash CSC S8

- CSC S8 OXM can cause the disappearance of the OEM

- Install the Ketan ROM version.

I am a little lost...
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
If you already have OEM unlock available then - Enable it first

Flash TWRP - Full wipe with 'yes' option - If you planning Dr.Ketan ROM then straightway flash Dr.Ketan N6 or Up if available (Don't use previous version) after wipe - Must select 'OEM Patch' in aroma - Done.

Reboot and check OEM available, If available, enable and enjoy, flash whatever except any thing that contains csc.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
B'coz I am using stock enforcing kernel (and probably only ROM around xda if i am not wrong) and that is normal with stock kernel once you 'Root' device.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
I have removed S8 csc OXM after multiple reports, will look into it if we can find something. Anyone here who can say what CSC was applied after flashing S8 OXM csc and OEM disappeared?
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Thank you doc for these clarifications.

So if I understand correctly I have to choose in the installation patch aroma OEM?

So will I keep my current CSC? (Xef currently)?

So if I understood the manipulation. Tell me if I'm good:

1 / I activate the OEM in the options developers

2 / Restart in download mode and I flash TWRP

3 / I go directly into recovery mode after flashing TWRP without turning off my phone.

4 / Complete Wipe / factory reset

5 / I turn off my note 8

6 / I restart in recovery mode and I flash Ketam Rom

7 / In the AROMA I choose OEM patch

8/ No need to root or flash magisk because Ketan Rom is already pre-rooted

9 / My note 8 restart after installation. I look if the OEM visible and I activate it.

Is I good in the steps? There is not too much?
[Samsung Galaxy Note 8 Questions and Answers] rocketmail.com:
Be careful with your step 2&3, putting phone off before going to recovery is not safe. it's a bit tricky, wrong move would send you back to jail.

After loading twrp in Odin and choosing auto reboot, it's better to put your fingers on recovery keys before start flashing and your fingers should be on keys till you get to twrp.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
You should keep ROM file on Ext SD

In step 4, it must be complete wipe, where you need to type 'yes' to confirm wipe.

Step 5 &6 not required, after full wipe, straightway you can flash ROM from ExtSD

and don't flash anything after ROM or later on which is related to csc
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Ok thanks for the information.

I go directly into recovery mode after flashing TWRP without turning off my phone.
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
I don't know why not to disable 'Auto Reboot' option in aroma so you get enough time to prepare your self

I prefer

- 1. 'Disable 'Auto Reboot' in aroma

- 2. When TWRP get flashed and 'Pass' msg display - Disconnect the device from PC and relax (Here this step give you some time to prepare yourself)

- 3. Keep Pressing Vol Down + Power

- 4. As soon as Screen went Off - Press three button combo to entr to recovery (Vol Up + Bixby + Power) - Done!

PS : In case in step 4 said above, you find that you were slight missed to press correct button to enter to recovery and in case you see a Samsung Logo - Immediately go back to step 3 above as early as possible. If device doesn't remain enough long on samsung logo, still you can escape from jail.
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Ok thanks for these explanations.

So for the CSC I will stay with the current (XEF), or in the aroma for the installation of KETAN ROM, it will be necessary to choose the CSC?
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
There is no such option on my ROM to choose csc

Simply select 'OEM Patch' that's it. and forget about which is your csc and which one is applied, if network have no issue then ignore and don't look to csc part ever.
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
OK, thanks.

I made a small mistake.

I activated the OEM unlock and restarted my phone.

on restart the OEM unlock option was obviously no longer visible.

However in download mode there is the mention

OEM LOCK: OFF

So I think my OEM is unlocking but the option is no longer visible.

My question: Can I launch the TWRP flash and start the installation procedure?

Or should we wait until OEM is visible again?

If I start the installation procedure of KETAM ROM, with this small error the option OEM lock / unlock will be visible according to you?
[Samsung Galaxy Note 8 Questions and Answers] dr.ketan:
You can try flashing TWRP, if OEM disappeared then it will through error. If it allow to flash TWRP then finish procedure as said. After flashing ROM If OEM not visible then don't reboot.

Personally I believe if OEM not avalable then it might throw error and won't allow you to flash TWRP.
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
Ok I will try.

After the disappearance of the unlocking of the OEM.

Edit :

Good doc small update.

My OEM was unlocking well. I restarted in download mode. I then restarted my note 8, and the OEM option was visible but unlocked.

I haveI re-lock OEM and restarted again my note 8 and it is still visible.

I start the procedure tonight and I install your rom. I will make you a return.
[Samsung Galaxy Note 8 Questions and Answers] zidane02:
Noob Question: When you say sent to jail, what exactly does it mean? You cannot use your phone? Brick? Or what? Please enlighten me. Thank you.
[Samsung Galaxy Note 8 Questions and Answers] Elin28:
Thanks dude. I am checking their website but even google translate doesn't do the proper job on the translation. I believe I will try other Rom once I got the OEM back
[Samsung Galaxy Note 8 Questions and Answers] Zayatoshi:
This means that the ability to unlock the OEM in the developer options is missing / Invisible.

So no possibility to flash TWRP and root his note 8.

Most of the time this option appears 07 days later.

[Samsung Galaxy Note 8 Questions and Answers] JeremySS:
I have a Vietnam version that I was originally in jail with for 7 days. After I was free I had flashed several different ROMS over the last month or so and greatly enjoyed living life as a free man. But a little over a week ago I broke the law and unknowingly had a blacklisted csc after updating my bootloader and modem, back to jail I went. So I Odin flashed the stock British BTU files and got up and running again.

Problem is that I am now on day 8 and OEM Unlock has not reappeared. Any ideas on why I am still in jail or suggestions on how to get a pardon?

Edit: Figured it out. Mine is a Taiwan model so I will Odin the BRI files and then wait another 7 days. For those taking notes, don't flash a Odin file that is not from your original region or OEM Unlock will never appear.

[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
ive been using this thread to try and help people on my rom, as i have never been in oem jail, its hard for me to have any worthy insight except for what you guys are going through. i see oxm is now not recommended, and being that i have DBT as one of my two csc options, i am looking to swap it out for another. What csc would people recommend that seems pretty universal? Thanks

[MENTION=3931450]dr.ketan[/MENTION] regarding the country code you see in download mode, i remember you saying you havent been in oem jail either. Is yours PAK? Because thats what mine is.

[Samsung Galaxy Note 8 Questions and Answers] 1em:
What happens when:

SCENARIO:

-For 1 reason or another, after having my note 8 rooted with custom ROM for over a month. Device rebooted and on splash screen with red writing an error came up along the lines of "only legit firmware can be flashed"

-As soon as that happened, I kind of just went ahead and flashed the stock firmware via Odin.

-All seemed okay I thought, but then, OEM unlock did not appear after 7 days, also getting error message when trying to open Samsung Health "can not be opened on rooted devices for sec. purposes"

= Now, Im not sure how to even explain it but here I go: Device status shows Official, can not flash anything via Odin. Only thing I have is the SD card full of my old stuff and TWPR backup.

Please someone explain what have I got myself into with this Galaxy Note 8 thingy with its OEM trickery.. Good one Sami

Thanking you very much beforehand kind sir/madam

Pak is for Pakistan, may be your device/sim from Pakistan?
[Samsung Galaxy Note 8 Questions and Answers] Mentalmuso:
Well it was purchased off eBay from a seller here in Texas USA. The seller is a dealer and sells 100s of phones.

That being said, yeah it probably was originally PAK, I have never flashed anything via Odin to this phone. Never upgraded bootloader or modem. Simply flashed my system and kernel.

Phone was activated with my USA TMobile sim card. Though who knows, maybe the phone gets activated somewhere else in the world then wiped before being shipped here for sale
