Hi mate, I have set up the tcpdump via entware on an Asus Router to do the traffic analysis (RT-AC68U, running 3rd party merlin firmware).

Then I used tcpdump to capture all packets sent from/to my Galaxy Note 8 from when the phone rebooted to system until the OEM unlock toggle showed up after a short vibration.

The connection is encrypted as I could not find out any string that contained "OEM" or "Unlock". Maybe I should try the MITM attack to decrypt the communication between my device and Sammy's server.

But I did find out something that might be somewhat related to this "OEM unlock".

As the phone was connected to rmm.samsung.com during that period.

Any suggestions? buddy, as I am not quite familiar with using the analysis tool.

I wouldn't say it's a waste of time but I tried it several times and failed. Not just Indian firmware, also Korean, UK, Malaysian, and I cant remember which Nordic firmware I tried, someone had reporting having OEM out of the box though so I tried whatever it was. However if you hit pay dirt I would say you're going to be pretty darn popular around here... :)
[Samsung Galaxy Note 8 Questions and Answers] fragtion:
If you are not getting OEM after 7 days, it's possibly a network issue. You should try to ping "rmm.samsung.com" from same data network that your phone is using. If ping times out constantly, this is likely your problem.

Or you could also try this -

Open your browser (on phone) to https://rmm.samsung.com/. After a few seconds, it should load a page "Welcome to Remote Mobile Manager. Please sign in to your account". (Do not actually sign in, as that has nothing to do with it and won't work anyway)

If the address is unresponsive, then maybe your network is blocking communications to this Samsung server, which we now believe could be the one which your phone communicates with in order to determine its OEM Unlock status.

It is not a confirmed technique, but worth trying if all else is failing

Just a quick update/info :

Yesterday the timer for my 3rd time in jail was up. OEM Unlock switch popped back up like clockwork.

It popped up already enabled with the description "Bootloader is already unlocked" (But we know that cake was a lie)

I flashed TWRP using Odin PC, then rebooted straight to TWRP.

From there I format (yes) the data, flashed no-verity

Then went straight to restore my NANDroid backup for Boot, System, Data. (My NANDroid contained Renovate ICE 2.1 and Magisk 14.0)

Then updated my Magisk to 14.3

Reboot again to recovery, the unlock still stick

Reboot again to system, the unlock still stick

No problem with multiple reboots after that, even after I update my ROM to Renovate ICE 2.2
[Samsung Galaxy Note 8 Questions and Answers] chloeleedow:
Can confirm Pre normal is gone when OEM unlock is there. Unfortunately not why but totally agree with you that this is related to the device being locked

Hi there. Does it still work if you shutdown your phone, then turn it back on?

I have 950F dual sim Taiwan version from never-msrp and after about 8 days, OEM Unlock showed up!.

I was using it without simcard, rebooted once a day and sometimes shut off. I inserted a simcard two days before OEM-Unlock appeared.
[Samsung Galaxy Note 8 Questions and Answers] Shreyu:
I believe we have the same phone. I got the 950 F/DS from the same guys. You got the OEM unlock switch after 8 days..!! Thats encouraging. I was about to return the phone to them..

Did you try flashing TWRP/ rooting the phone already? Really appreciate your inputs and your efforts.
[Samsung Galaxy Note 8 Questions and Answers] FX-32:
I wanted to return it too, but restocking fees and shipping times made me think it twice... I resigned to use it without root privileges and then after i gave up and finally started to use the phone, OEM-Unlock showed up.... Now I do not want to loose time doing backups and experiments... I'm giving it a try using it stock, with BK-Disabler debloating app and bxActions to remap bixby button... So far it works OK, i want to wait more time this way because I do not want to install a new rom or something and have to wait again for oem unlock to show up if something goes wrong...
[Samsung Galaxy Note 8 Questions and Answers] david744:
Same here I imported xml file by BAYmustafa96 credit to him and its all working great, now just waiting again
[Samsung Galaxy Note 8 Questions and Answers] Andysmith71:
Second that as I'm on Telstra as well and I've had the timer success twice now, so no reason it should not work for you. Just do the full stock restore and make sure your connected to network / wifi when setting up, you should then be good to go after a week. Kies is a good option as you know it will return it to stock guaranteed and your count down timer will happen for sure. :good:

Good luck!

Also hit me up after you are out of jail and you have set up custom rom, I've modified the CSC utility to work with Note8 so you can change your CSC to work for Telstra and get Volte / WiFi calling. Tested and working on Renovate :good:
[Samsung Galaxy Note 8 Questions and Answers] evangelionpunk:
Would inserting a US sim card into a brand new unopened sm-n950f/ds set its CSC as US or will it still be Taiwan?

Seems it installs Samsung Pay Taiwan even though this was done? Would Samsung Pay still work though the offers are in Taiwanese?

They do not have a fix for this either sorry.

[Samsung Galaxy Note 8 Questions and Answers] evangelionpunk:
Are you certain? I read on here that the CSC for unlocked devices automatically changes on first boot or factory reset depending on the sim card inserted.

The SM-N950F/DS isnt a US model anyway. This one came from Taiwan unlocked and region free. No OEM UNLOCK yet.

What to do?
[Samsung Galaxy Note 8 Questions and Answers] krabman:
Lots of people have been there before you, your options are waiting or waiting. If you don't want to do either of those you can alternatively opt to wait instead.

As to the CSC it's multi and will choose among them if your SIM is native to one of those CSCs, yours is not. You will get basic APN support and that's about it.
[Samsung Galaxy Note 8 Questions and Answers] evangelionpunk:
Waiting it is then :)

Does this Taiwan sourced SM-N950F/DS normally ship with the global XSM csc since its sold almost everywhere or is it Taiwan specific CSC and needs flashing?
[Samsung Galaxy Note 8 Questions and Answers] krabman:
I haven't flashed the CSC on mine as I don't use any T-Mobile features that require TMB. Perhaps someone else can come in on that one that has real device specific experience. Global or world CSC is a bit of a misnomer, the US and others are not in there. Your phone or any other FD are grey market n the US and Samsung does not make a world phone per se, all are regionally localized to some extent in hardware, firmware or both.
[Samsung Galaxy Note 8 Questions and Answers] SimplyCity:
Guys, I can tell you that we are trying here at Echoe to figure out a fix for all without OEM. But I am not sure if that can be achieved just by flashing modded "official" stock rom (only one can be flashed with Odin since OEM reappears or was absent from beginning). What concerns me most is that "AAM state: prenormal" thing. No one knows why it is shown at all. Is it connected with wireless lock they seems to implemented and even we find software way to unlock OEM, will it work till they put device ID (or something) on to approved list? Or is it some kind of knox fuse, but kind of software one, and can be changed by properly modded stock rom?

...

There is a lot of unknown. I personally own N8 which has OEM out of the box, but it is gone and don't want to show up again. I don't know why I suffer this, it looks like we have only few users with such surprise, every other Echoeneans with N8 they used OEM unlock once, flashed our rom normal way (format data - yes, dmverity, rom + Magisk, with recovery reboots when needed, nothing more) and since there no one went to 7-days prison even they reflashed rom or new kernel a lot of times...

**** happens...

But we got a law here where I live. And it says, that if goods you've bought changed the state it has at the day of buying, seller has to reset that state it was at the very first day. I am not sure if I wrote it properly, but I hope you understand. I personally put a claim and demand (from seller) to bring OEM unlock back, like it was there when I opened device for the very first time, in other words: incompatibility of the goods with the contract.

I don't know if my provider can help me with that. I hope they will, bc now device is just unusable (additionally, in current state no android pay nor secure folder nor Sammy pay work) and I am covered by local law.

If we, at Echoe will figure something out, you will know.

For my N950FD from the Philippines. My OEM unlock appeared exactly after 7 days from when i inserted my sim. Flashed Lightrom and other stuff since then and was fine. Flashed another rom that overwritten CSC and boom, OEM unlock gone. Switched CSC to BTU thru *#272*IMEI# since alot of people say thats unbranded and OEM unlock never went away and still no OEM unlock. Bootloader says FRP Unlock is off and OEM Unlock is off too. But Prenormal is there.

After 168 hours (7 days) of having my phone on, OEM Unlock became available. I purchased it from Never-MSRP eBay store (Which mine was the Taiwan variant N950F/D , waiting the allotted 7 days and the OEM Unlock option came available, and now I am running Renovate ICE rom.

I'am from Germany and my Note8 (SM-N950F) comes from mobilcom-debitel(vodafone) [DBT] and when I open my box (which was not shrink-wrapped) the developer options was also allready activated on my Note8

I have that OEM Switch frm the beginning and i switch it to off, but didn't root or custom recovery so far.

OEM after 7 days / must be signed in to Samsung acc!

As I mentioned before, the OEM option became available initially when I bought the device after the 7 day being On.

Then when I got the ROM I wanted, I factory reset my device (to start fresh I though) but to my shocking discovery OEM was gone..

Just then, and I did restart the device again after that and again the time up - gone to 0. But I realized that all this time after factory reset and waiting for additional 7 days - I skipped on Samsung account and google account sign ins. So I smashed them in just 5 min ago and booooom we are in business !! OEM appeared immediately !

Conclusion: Login to Sam / google acc's and the 7 day thing is without guesses!

Thanks for your time everyone, hope this helps and happy rooting for me now :D

If you want a Note 8 and do not need the dual sim do yourself a favor and get a UK F version from Handtec, Clove, etc. You'll have OEM immediately and can skip this nonsense.

hi.

you're right man i had ordered a note 8 F model O2 model unlocked

it has oem unlocked out of the box shopkeeper told me

i think they unlocked it in uk so they power on it there after 7 days it must be oem unlock in developers option.

it will be delivered to me in half n hour.

so now please tell me what shoud i do now

i m downloading RENOVATE ICE N950 2.2

please mention some authentic procedure for flashing it once.

thanks.
[Samsung Galaxy Note 8 Questions and Answers] krabman:
No, I asked one of the outfits how they do the region unlock and the process for them was pretty simple. They open multiple devices and use one to call the others via conference call. They let them all sit for 6 minutes on call, end the call, pull the SIMs, do a factory reset, shut them down and carefully rebox, ship them. Some versions of the phone come with OEM lock available, Samsung has not published any information regarding this and no one outside of Samsung has figured out exactly why some international versions have the OEM unlock timer and some don't.

As to installation, you need do nothing special. Enable OEM unlock and then simply follow the instructions on the TWRP thread to get recovery and root and you can install renovate in the same flashing session. Good luck and enjoy.

Is this the basis of the OEM unlock timer? It shows the first login date/time of the Samsung account on the Note 8. It recently got reset after my csc got overwritten. Previously when data and/or system were overwritten, it would still stay at the original date I got the phone. It is under Settings, Cloud and Accounts, My Profile, Manage Samsung Account.

So far I've been good since my first OEM unlock appearance.

Followed [MENTION=1230317]krabman[/MENTION] original post on what he did and been over a month Now flashing and rebooting without an issue.

I do tho perform a data wipe (yes) before every Rom installation which may help.

I also originally had OEM unlock enabled for 2 days before I originally rooted etc.

Fingers crossed still of course.

So far so good and loving the note 8 with custom recovery on the N950F/DS
