after clicking build date 5 times go and press back cutton twice to get to normall settings and dev options should be the bottom one:highfive:

If it's still not there you need to wait 7days for it to appear.

Correct

Got it to show without waiting 7 days.
I'm on CRED firmware and OEM Unlock was not listed.
I read somewhere that invoking the Oreo Easter Egg might make OEM Unlock available again.
This is what I did:
* After flashing CRED via ODIN and gone through initial setup, OEM Unlock was unavailable
* I only have a gmail account setup on the phone, no SIM
* I followed the guide here for the Easter Egg in Oreo: https://www.pocket-lint.com/apps/news/google/138312-how-to-access-android-easter-egg
* Once the octopus showed on the screen I moved it around a little
* After 3 tries OEM Unlock option was still missing
* Rebooted the phone
* Waited a few minutes after the reboot
* OEM Unlock appeared!
I can't give exact steps but after playing with Easter Egg several times and a single reboot, option is available.
I got this phone yestreday.
Hope this helps someone.

I try it but not work.

Yeah, I tried it again after my phone got re-locked and I can't get it to show either. Like I said, I'm not sure what I did and what caused it to unlock. It did happen once but I can't go it again.
I'm waiting the 7 days since I'm already on U2 bootloader and can't go back to U1 bootloader.

This trick works for me:
1)- change phone date back 8 days
2) go to software update and check for update. You should receive errors info
3)- restart phone and go to Developer Options and you should see OEM Unlock appear back.
You may try checking software update few times to get it work.

So change date back 8 days, did you disable automatic network date/time setting?
All i get is errors when checking for updates, is that ok?
When you did it, did your update check ever succeeded or did it fail every time?

Bro, I guess you applied this truck to Oreo, right?
other thing, when I check the update manually, do I have to be connected to the internet? or with the data and wifi turned off?

Good question Aspiranteh, was this used with a U2 bootloader (CRED in my case) or a U1?

SUCCESS!, I don't know specifically how but I just reviewed "developer options" after several failed attempts and to my surprise now if "OEM unlock" appears. Thank you very much @vichet007 it's most likely thanks to your trick.

Which bootloader are you on? U2?
can you describe what you did in steps?

*Excuse me, but how do I know if I'm U2 or U1?.
And as for the steps, I did exactly what vichet007 says.
On the date go ahead to 16/06 and test with "Automatic date and time" activated and also try it with that option disabled.
In the "Manual Download" test update with data and wifi enabled and also try with data and wifi disabled.
I tried it 10 times on the quiet and it didn't work out. But after a while. Check and this OEM unlock is activated.

**FIX** BL Flashed through RMM State Prenormal (OEM Locked) - IMEI/BASEBAND RESTORE

Excellent news and a solution i havent found anywhere else yet!
Follow up from - https://forum.xda-developers.com/galaxy-s8/help/restore-imei-attempt-stock-rom-flash-t3802527
TL;DR attempted to re-root as soon as the bootloader unlocked. It all seemed to stick again, and got the big red message of doom again.
"Official Binaries Only" - Last time i was able to restore to at least switch on the phone to run down the rmm state timer to zero to flash again.
Tried the several methods of flashing through a locked bootloader (old BL file, quickly restart download mode and spam start on odin, etc) - literally nothing would allow me to flash anything that included the BL file. IMEI and baseband remained unknown. Phone went in drawer for a few days.
Just went and downloaded the latest XSA (Australia, Unbranded) build - https://www.sammobile.com/firmwares/galaxy-s8/SM-G950F/XSA/ and guess what boys and girls?
This sucker flashes straight away with Odin 3.13.1
It has completely restored my IMEI and baseband, i now have full Cell connectivity again, and its all back and working again. OEM unlock is still disabled, Samsung Pay still locked out which is fine, but otherwise, i have gone from brick to fully working Exynos S8 again.
TL;DR IF YOU HAVE ISSUES WITH A BRICKED PHONE BECAUSE IT WONT LET YOU FLASH ANY STOCK ROMS TRY THAT ONE.
Thanks for the replies to my other threads trying to help out with this. Much appreciated.
Peace out.

For heads up for other after this, how to get OEM unlock to pop up again.
Go-to date and time, change the date to 8 days prior, disable automatic update of time.
Reboot phone and it may take a few tries, but OEM unlock should pop up again in developer settings.
Just went through all this without any help and it sucked lol. Thanks for making this thread for everyone.

Ive had a few cracks at this now but the date keeps resetting itself when you reset the phone despite having the automatic update option switched off.
Thanks for the info tho ill keep trying.

I havent been inside since i replied to you before. Gave up trying to fix that and was doing other things. Just reset both the s8 and s8+ to look at download mode... noticed the rmm flag was GONE rebooted and sure enough OEM Unlock is done.
You genius.
So - Anyone actuallly reading this -
Lost root, reflashed and cant install TWRP etc, "OFFICIAL BINARIES ONLY" crash, cant replace bootloader, missing IMEI/Unknown baseband -
TRY FLASHING XXU2CRED stock rom from 18/6/18 or later. This will flash despite a locked bootloader.
Once up and running set up the phone for use. Reboot as normal. Then turn off automatic time and date set date to 8 days prior, reset phone a couple of times. Get annoyed because you keep having to reset the date backwards. Reboot phone again and set automatic tin me and date again. Reboot. Bamf unlocked and completely restored SN-G950F.

Ah I should have also mentioned I also did the same, flashed the same firmware when I was desperate and after some bit I also noticed prenormal change to official in download mode (the tell tale). I had OEM unlock on always, just was stuck in prenormal mode and couldn't flash anything.
To speed up the OEM unlock trial and error process do this as well:
1. After setting time/date back 8 days (and auto update time off). Go-to updates in settings, select manual update and check the server (it will error probably but that sets a check on their server to allow the RMM state to change next time it's connected properly).
2. Do this quite a few times, with reboot and constantly fighting the date auto update.
3. Flash the CRED firmware mentioned, boot it and setup once. Then reboot and go-to download mode.
4. You should see official as the RMM state now and you can happily OEM and flash away!

Have just flashed TWRP, used the Comsy version to be safe (3.13.1 fine for the stock rom flash) - I used comsy as it is mentioned in hte post OREO S8 update. It allows TWRP to be flashed but maybe thats whats breaking everything else. Ill try magisk next.
Fire up TWRP and enable system changes. FIRST - Advanced wipe and format system (Im 99% sure this is what screwed my last couple of roots), hit yes and do it. Reboot into recovery again.
Flash no-verity, then SuperSU (or your preferred root, i use Aroma installer first, THEN you have to flash the SuperSU binary with that)
Wipe dalvik etc. Reboot into system. As i type this its now in the 'Welcome' screen. Gimme a minute and ill check all is good.
UPDATE - Everything restored installed titanium backup root held. Rebooted phone aaaaaaaaand - "Only official released binaries are allowed to be flashed" - Back to square one. Will attempt same reflash now, but the root procedure kills everything. Back in download mode again. RMM State: Prenormal returned.
It is now succesfully flashing the stock rom in Odin 3.13.1 - Accidentally started it with Comsy and it DID NOT WORK. You MUST use the normal version to flash the rom im using.
Looks like we def have a stable way to refire up the phone again, and get around RMM state prenormal nice and quickly, so ill go ahead now and try and find whats going on with things breaking afterwards!
Thanks again guys.

Did nearly the same as you, dejavu.
I use magisk though. Be sure to flash a rom or kernel with RMM state fixed lol, or you'll be back here soon.

Someone should clean this up and get it stickied.
I imagine there are alot of users here with this same issue, after the CRED update we can't downgrade our bootloader, and in a panic you can get stuck here.

Looks like that wont be an issue any more to be honest this phone is now a backup thankfully so i can play around with it to my little hearts desire.
Im about to try the magisk install. SuperSU/Aroma definately breaking something somewhere. Or verity. I dont know but rooting the phone at the moment is killing it again.
Also, i have NOT lost IMEI or baseband this time. At the very least for Australian SN-G950F phones, this is a 100% flashable stock rom regardless of your RMM or phone status. I cannot say this for any other model in any other country on any other carrier, but this is all working for a carrier free Exynos S8.
Maybe y'all better archive the actual stock somewhere before someone realises theyve made a mistake somewhere and it gets pulled. Im definantly backing it up.
I just got that oem unlock trick to happen in 2 shutdown/restarts NOT reboots. BUT. I did NOT enable developer mode until i had disabled automatic time updates and turned the date back 8 days. The option came up instantly. Is something comparing a hardware clock deep in the system to a software clock in the os to and developer mode comparing something in between? Either way, on to reflash TWRP again now. This is a good day.

Hokay so - From a factory refresh, to the OEM unlock trick -
Flashing TWRP with 3.13.1 and allowing the phone to reboot - Phone will reboot as normal, TWRP doesnt stick. Shutdown and reboot into recovery gives you stock recovery.
Flashing but ensuring phone reboots directly into recovery gives you TWRP. A format data and reboot directly into twrp again lets me install no-verity.
- AFTER DOING THIS I AM GETTING THE RED LINE OF DEATH - Something in the system isnt letting the modifications stick.
Reflashing with the Home_CSC still seems to work as normal and i havent had to go through the welcome stuff this time...

Have you found and used this after getting your phone setup right (w/twrp)?
I think you should flash magisk, then this after.
After I had this "panic" I flashed the custom rom I was aiming for (once RMM: Official). That rom has a kernel with the RMM state fixed/locked.
Maybe look for a custom kernel if you want root, I believe this is the fight we have to put up even on stock w/root.

Download the Australian stock rom and install it but do not recover IMEI or coverage. I think it's because my G950F (singlesim) cell phone thinks it's G950FD (double sim). This causes the cell phone to get confused and not recognize any imei or sim. Does anyone know how to fix it?

I was stuck here too, flash the latest CRED firmware he linked.
Then boot it one time (setup til you see launcher).
Do the OEM unlock method.
You can follow the steps after if you want root.
I suggest magisk and a custom ROM, that had RMM state fixed (so you won't get locked again).
Good luck!

Sorry i missed your reply i hope you got it fixed if not post again and ill see if i can help. Ive definantly gotten that oem unlock trick working which is awesome but its fiddly. I dont think it works if you turn on flight mode and you have to let the phone fight you between 'no automatic date and time' and the network forcing the time.

Of course now i cant get the oem unlock trick working...
RE the dual sim issue... i think you would need the stock rom specific to your model try sammobile, see if there is a CRED release for your model. I cant guarantee it will work tho.

Thank you for your help, I am on the latest firmware now and into my Google and Samsung accounts. I am a little confused on the wording in the oem steps. I have tried it a bunch of times. Prenormal is still there, I already have the OEM unblocked, I can toggle OEM on and off but it doesn't change my rmm status. I am not sure what I am doing wrong.

Thats exactly what im now struggling with. It absolutely did work twice but i cant get it to go now.
Heres the thing - both times i did it before, i would turn off automatic time and date and set the date backwards, then reboot the phone, when it reboots, automatic time and date were rechecked, and the date reset to now (hence the 'fighting with the date' comments) ... i think thats important, because now when i try it, automatic time and date stay OFF, the date does not reset, and i cant get the trick to work anymore. No amount of wifi/airplane/mobile data on/off seems to change owt.
If anyone reading has any ideas it would help.

I see, so you suppose to set date back 8 days and turn off auto time and date and restart phone? When it comes back on to and set the date back to 8 days again? I thought you have to check the software? And then do those steps? So after I change the date back after that first restart, then what? Do I just turn OEM lock on and check download mode to see what the status is? I am not trying to be a pain o am just confused a little on the steps. Thank you for all your help

I think we might be looking at different issues.
This is to fix a semi bricked phone that has locked up its bootloader. In the past to resurrect a samsung all you had to do was flash twrp and your new rom but since Oreo some funkiness has been added to the system which only lets you flash a stock rom, (i.e. restoring a phone to factory settings and software) via ODIN/HEIMDALL then it locks up the bootloader for a week so you CANNOT flash anything into the phone that modifies the bootloader (i.e. TWRP OR *any* rom) until its timer runs out. This is most likely an anti theft feature esp with samsung and google pay use as it means there is no way to easily break into a stolen phone and use it as normal, and reflashing breaks all of the security features of the phone (e-fuse) - no knox no samsung or google pay no samsung pass as your device is insecure and could spoof false banking details etc.
The rom i linked to is important as it is a new AUSTRALIAN unbranded STOCK rom, that for some reason you can flash OVER a locked bootloader, meaning you can resurrect (australian at the very least) SN-G950F phones (exynos)
If you already have a working phone and can get to your developer settings then most of this thread is irrelevant to you.
Now - OEM unlock - You just bought a brand new galaxy from samsung (or youre me and you bought a MINT second hand one from cash converters for $700 less) - your phone is factory standard and schmicky. THE BOOTLOADER IS LOCKED. THE RMM STATE SHOULD NOT be triggered. If right now you went to flash something it would fail.
So you go to about phone - software information and you tap 'build number' seven times to unlock developer mode. Hit back twice and developer mode will be at the bottom of settings.
Click into this and you should see without swiping down 'OEM UNLOCK' - If you enable this, you can then reboot straight into download mode (power vol down and bixby) and flash twrp or whatever rom.
If you dont see this option, you either have a snapdragon model (youre **** outta luck permanently) or RMM is PRENORMAL and you either have to try the unlock trick(s) or leave your phone SWITCHED ON for 1 week and it will unlock itself.
The biggest issue at the moment is that i keep breaking something after i attempt to root so not sure whats happening there so use major caution.
Now as i said the trick posted above to unlock without having to wait a week (which i think youre asking about) im now not sure how it works because i cant get it to work any more.
Automatic time and date off, set date back 8 days, reset the phone. Do this a couple of times, then turn on automatic date and time again. HERE THERE BE ISSUES. When i first did it - i switch off time and date and change then reset, when the phone came on, auto date and time was on again. Turn off, change date, reset. Again, its back on. Turn off, change date, reset. Its back on. I give up and leave it, and notice later the option was available, so it worked. I broke the phone, reflashed again, did the trick in ONE reboot. Fcked something again, reflashed, now auto time and date stays off and the trick wont work so i cant help you with that until someone comes up with more info im sorry! Its a bit zarbis.
Im not going too nuts trying to fix it as i now have a fully working stock backup phone that sits on DeX plugged into my bedroom tv full time and im not into custom roms, root keeps breaking the phone, and ive sonce replaced it with a mint S8+ that im not even THINKING about considering rooting until its replaced maybe next year. Its not as easy to get around anymore and thankfully a) picasa and hangouts are no longer stock apps and can be banished and b) you can now disable all the other built in apps natively so its now a lot more bearable with a totally stock phone.

CRG1 OEM Unlock?

Hi all, I have a G955F and upgraded it to CRG1. The problem is that there is no OEM unlock toggle to be found in the Developer Options section. I've tried to bypass the 7 day wait by changing dates and that didn't work. Is there any other process I could try besides waiting 7 days? All help is appreciated, apologize if this has been posted before.

It should be there.... I say u should wait for 7 days.

Mental fireballs in your direction.

Sorry guys, I didn't get a notification for your replies. All I did was reflash my phone's firmware and then performed the calendar date trick.

I didn't get the OEM unlock option even after the 7 days wait, I am on latest firmware CRGH, can anyone help me out here??

Should I flash HOME_CSC or CSC ??

Hi all, I have a G955F and upgraded it to CRG1. The problem is that there is no OEM unlock toggle to be found in the Developer Options section. I've tried to bypass the 7 day wait by changing dates and that didn't work. Is there any other process I could try besides waiting 7 days? All help is appreciated, apologize if this has been posted before.

I tried flashing CRG1 and CRGB as well as CRGH, I am not able to get the oem unlock option after the date trick. Any help??
So I am thinking to stick to the old firmware with bootloader version 3, can you tell me which one is older CRG1 or CRGB??

New Update
I again refalshed CRG1 which is the older one with bootloader version 3, then I tried this date trick, first it actually did not work. So I tried and monitored my procedure every time. It worked finally. Here is the step by step guide,
1. Reflash the firmware and skip all account setups
2. Now change the date 20 days back
3. Now go and enable developer options
4. Check for OEM unlock(probably won't be there), now disable Auto update system
5. Software update option, disable automatic updates
6. Click on update manually(now you will see registering device toast message and a persistent device configuration notification), it will show you there is an update based on your region(I downloaded Poland region firmware). Most of the post about OEM unlock says you will get an error here due to date issue, but you won't get any errors.
7. Now do this step as fast as you can, again check for OEM option in developer settings((probably won't be there)), and reboot.
8. You should again see the persistent device configuration notification, Turn off wifi/data immediately. Now your date must have probably changed to current date even though you changed it earlier, change the date again, now when the notification goes off, go to software updates, turn the data/wifi on. check for software updates.
9. Now go to developer options you should see OEM unlock option.
If it doesn't work, shuffle up the step 8 instructions, like check for software updates first, then change the date and vice versa.
Samsung got a ****ty logic written under the code over there, but its messy. So I tried this multiple times just to make sure no one else end up with this issue. It worked for me probably it should work for others.
Better download the Poland firmware CRG1 and try it.
Thanks.

U dont need trial and error for this.
1. Enable developer options and check if OEM Unlock is already visible, if not proceed below.
2. Disable auto software update and mobile data to prevent auto date correction.(Leave wifi on)
3. Adjust your datetime to previous dates, let's say Month of May 15th, 2018.
4. Do Software Update manually, do multiple taps so that Software Update process will appear.
5. It should display an error in software update.(Let if fail)
6. Reboot
7. Once rebooted, change the datetime to older dates.(since date will revert back to present)
8. OEM Option should be in the developer options.
Im using the CRGH build, and it never fails me. never waited for 7+days idle phone,no trial and error, I just follow the simple steps above and OEM Unlock never disappears in my end , it was never "patched" as others have told.
Using XTC/SMA/GLB region firmware CRGH build, SM-G950FD..
Note:
I reverted back to stock due to NETFLIX and other related streaming premium apps not playing HD+ content. No workaround or permanent solution on this yet. I'm paying premium 4K hd content so it would be a waste of money playing netflix content on rooted device with just SD video.

OEM doesnt ever show up

Hello, I could really use your guys' help. I am aware of the 7 days wait for OEM unlock to appear on the s8 exynos because of RMM: Pre-Normal. I have waited for 7 days for about 3 weeks and have not turned off my phone during these times. I have never seen OEM unlock appear once. I have also noticed today that, my RMM is never pre-normal and is only ever Normal. No matter which firmware I flash. What else can I do? Is phone somehow broke? I have Flashed BTU, XEU, and XSA. All nothing even after 7 days.

Flash the latest multi csc firmware with odin:
https://fws02.updato.com/GALAXYS8/SM-G950F/DBT/SM-G950F_1_20181012085940_qn0samjn69_fac.zip
Set it all up and then do this:
Go to Settings and activate dev options.
Disable automatic updates and "Never disconnect network".
Go to date, disable automatic time and date and set it back 7 days ago.
Go to update, disable automatic update and check manually for update.
Disable all networks, wifi and data.
Restart your device into original recovery and clear cache.
Restart it.
Have a look if OEM Unlock appears.
If not -> Set it back again 7 days (14 days at all) or more and restart your device.
Dont clear cache or so.
It will show the date 7 days ago but thats okay.
Again set it back and restart.
Don't forget to check for updates while changing date, unless there is already "last checked *date of past*.
If it now doesn't show up, set the date back to automatic and restart your device.
Play a little bit with settings the way I described.
That worked for me sometime.

I have read that this workaround was patched after the August update. I cannot downgrade as im on U4. Any other workarounds?

Does anyone have OEM Unlock on the SM-J530G?

I've been trying for a long time to get OEM unlock with the Samsung Galaxy J5 Pro SM-J530 G variant. I've seen people unlocking the BL in the J730G, same exynos chip.
Here is what I have tried so far:
All date/time tricks
Factory reset
Flash Stock ROM
Waited 7 days
My last attempt made me give up and ask for help here... I completely flashed the most recent stock rom, wiped everything using the CSC file not the CSC-HOME, I did the start setup logging into samsung account and google account, after completing the start setup I inserted the SIM card otherwise that stupid start setup would consume 4G costing me $$$.
Waited for 168 hours with the device always on, and still no OEM UNLOCK, I mean what else can I do... there's almost nothing about this problem with this device here on XDA... I'm hoping someone with a SM-J530G and that had OEM Unlock could tell me what was the process to enable this option. Or what are my options here? Thx
And by the way, I've seen something called Miracle Box, but I dont want to use it since it does not look very legal, I think its meant for FRP bypass. I'm just an android user trying to root my personal device e.e

I'm having the same problem, I'm tired of this, never buying Samsung again. I tried all the things I searched on the internet for hours and nothing works, I do not want to wait 7 days, if you find a method of bypassing that actually works, please do tell me, I will do the same if I find one.
I'm so pissed.

I have good news for you my friend, and for everyone that is reading this. I tried many and more times the same procedure changing small things. I will try to write it out as best as I can so I can help some fellow buddies who've got the same problem.
1 - (As I had already everything backed up and got nothing to lose) Factory Format the device (I did it from the bootloader), hell, I even also cleared cache just for god's sake.
2 - Proceed to initiate Android, DON'T sign-in to any account (nor Samsung nor Google), don't change the date during installation, finish set-up.
3 - DON'T enable Developer's Mode yet. Change the date, I've set it for a month back just to be damn sure (disable automatic date-set). Now go to the Software Updates tab and disable auto-updates and manually check for updates, once done, re-boot.
4 - Once rebooted enable auto-date (that should correct the old date and replace it with the actual one) and re-do the manual check.
5 - Re-boot and enable Developer's Mode and hopefully, for the love of Ragnar Lothbrok, OEM Unlock should be there. I hope it is for all of you.
Hope it helped, good luck buddy/buddies!

That is awesome! I'm going to try it tomorrow, I've been using the device doing my third 168 hours. If it fails again I will repeat everything like you did.
Thank you!!
Sent from my SM-J530G using XDA Labs

Another 168 hours wasted and I followed the trick above, it does not work it was patched with the august 2018 security patch, my device is running with the november 2018 security patch.
My frustration is beyond what I expected to experience with this device... I guess most people were able to activate this thing except me >.<

Enlighten me
When you keep it for 168 hours does the WiFi have to be on or is that not necessary

I tested with wifi always on and logged to google and samsung account so it could sync whatever it had to sync, still no success. I have no idea on how to meet the requirements to unlock the BL on this phone

Is their any other method for 2019.am at my wits end

OK I tried something and it worked to unlock the oem.
Have a Samsung account,then go to find my mobile website and press unlock.it did the trick for me.hipw it helps you as well

Firstly, i use miracle box and then i use samsung tools pro to "reboot" my device because when you unlock the bootloader there is a fail on the room.
here you have a video which could help you.
