Solution: Stuck at 50% when unlocking bootloader of xiaomi Redmi Note 3 SD.

I must be very lucky to have unlocked my phone after only one week after I got permission. I tried so many methods but always stuck on 50%. Before giving up and trying unofficial way, I give it last try and Woilaa I succeed. I did lot of research and I believe all information located in phone should be perfectly match to your MIUI ID/Forum settings in order to unlock your phone. So you will need below prerequisite.
PREREQUISITE (Exact what I have done to unlock my phone)
1) Go to your phone setting>My Account>Personal Info> and fill personal Information and Phone/Email. Now go to MIUI forum settings and fill exact data that you have fill up in your phone. (Including your forum username should be same as the name under personal info into phone setting).
2) Also check “Your device and MIUI version” under basic information tab. That should match with your Phone/MIUI version (when it perfectly matches stop upgrading your phone and try to hold MIUI version shows on forum setting, I unlocked my phone on Global MIUI8 stable V8.0.2.0.LHOMIDG).
2) Go to password tab (MIUI forum) and setup security check-up bar to 100% (by setting up 3 secret questions).
3) Add recovery email and recovery phone here (should same as Phone setting).
Now wait at least week after you got permission (I got it one 28-Sep and succeed on 6-Oct, exact after a week)
After week try this method to unlock:-
1) Disable Driver signature enforcement.
2) Remove all locks/patterns fingerprint. Also remove app lock and disable it.
3) Go to developer option and check USB-debug and OEM unlock (if already check then uncheck and re-check it).
4) Go to i.mi.com login with your id (same procedure mentioned all over internet) and check device shows online or not.
5) Check your device is online (should be "Online located just now") IMPORTANT WHEN YOU REFRESH FIND DEVICE BUTTON, YOU SHOULD NOTICE YOUR PHONE SCREEN FLASH or BLUE ICON OF "LOCATION SET BY GPS/SEARCHING FOR GPS" ON NOTIFICATION BAR. (I believe if this happen means your phone is successfully connected to MIUI servers, I failed before many times when I was online but never notice flash/blue icon until last time I succeed)
6) Run unlocks app with “run as administrator” and login with YOUR MI ACCOUNT ID not with your phone number or email.
7) Unlock the phone.
Hope this help anyone

Every time I brick my phone by messing up partitions and I will fire up miflash and flash through edl. I will reboot the phone and will go to fastboot mode directly after flashing. I will launch miunlock tool and clock unlock, even though I didn't even boot up the phone, it will unlock the bootloader. I did this more than 10 times and worked fine. No need to remove app lock, fingerprint, etc. The OEM unlock option in developer options should be enabled to unlock. I think the mi credentials are stored permanently in some place. I am trying to figure out that place where it stored the credentials.

You are right, MI must have stored the credentials somewhere. I think most of people stuck for the first time. Once you unlocked bootloader, it's easy to unlock again. So may be you were lucky to not faced problem at first try and now you are able to unlock it 10 times.

I think, Mi utilises a digital key similar to those used by Microsoft to activate Windows 10 licences. Once you sign in on a device with a certain Mi account, the server on Mi end ties the IMEI and Device serial number to that account. And, this is the information the MiFlashUnlock searches for when you log on to it. Of course, once you have unlocked your phone, that information too is stored on the server-end, enabling you to unlock your phone multiple times, if it ever gets relocked.
This is my hypothesis anyway. I may very well be wrong.
And, I think the key to unlocking is to remain on the same MIUI version for more than 7 days on a stretch. I did just that and voila, the unlock worked.

Yes, but mine finally unlocked immediately after installing the global dev ROM. It would never get past 50% on 8.0.1, 8.0.2, or 8.0.5. I think there are several factors ( bugs) that cause it to fail, and that those factors interact in various ways that no one here fully understands. So we get all of these elaborate processes that work for a couple of people, but then fail for many others. Oh well.

Yeah, I understand your frustration. I gave up waiting and used the procedure to flash ZXC TWRP with a locked bootloader. It worked perfectly and I was able to install SuperSU and Xposed on MIUI. I tried officially unlocking one last time after that, and it worked. Go figure.
Good luck.

Current account is different from the account on device.
It's been a month after getting official permission.

Yes, it happens. I got unlock permission on 13-August-2016 but was able to unlock only on 07-October-2016. So, I don't really know how long it will take for you to be able to unlock your device.
One thing you can try is to not update MIUI for about 15 or so days and then try to unlock it.

Will wait and keep checking every few days.

Have you check MIUI version mentioned on your forum setting is same as your device or not. I believe verification of device fails because information stored on Mi servers not matches to your device. So better option is maintain MIUI version shows on forum with your device at least 5 days and stop upgrading your phone once it matches (keep phone connected with Internet during these days so server can interchange data with your device). Good luck.

Well, we build many hypothesis how Xiaomi unlock phones. But it is fact that Xiaomi software sucks at unlocking, rather they should have mail us unlock code like motorola does.

He mentioned he had to add phone number in forum same as in phone setting. Also match device model on forum settings. That is true, what I try to point out in this post is you need all information perfectly matches between miui server and your device (some unmatched information like miui version, phone no etc works for some people and some not work). In a nutshell, try to match all information saved on device to miui forum settings. It should works.

I think we should try at max. those steps which we have control like flashing global dev, having only one sim also in the 1st slot for which we've got permission etc. just to maximize your chances of identifying yourself in the server.

No, nothing happens. The bootloader just remains locked, that's it. The phone continues to function as before.

oreo oem unlock

I have a Samsung g950fd , just updated to official oreo on air.
I used to flash roms earlier but now after the update I can't seem to find the oem unlock in my developer options?

delete.

The Rmm states shows prenormal
I'm guessing I'll have to wait for like 7 days for the oem lock option to pop up.
No way to get it before hand?

Alright mate.

Hello! If it is before doing root, you have to delay the date setting of your smartphone for 7 days. After that, restart your phone with Wi-Fi enabled and if the date does not update automatically, go to date settings and return to automatic date and time, and that's it. Then unlock the developer mode and the oem unlock will be available. However, after root, the oem is locked again, so you have to wait not to block by frp.

Have you even tried for yourself ,lol.
It does not work

I tested the G955FD that way and it worked.

I tested too and it works with the phone in airplane mode... I was locked again and now i can't delay the date anymore, everytime i restart the phone it sets automatically the current day...

Hello. I Also have the s8 SMG950FD, oreo, had my phone for almost a year and do NOT see de OEM unlock option. Whats going on?
Please Help!!!

Missing OEM Unlock Option.

Alright so im dead set on rooting my phone once i realised why the **** not. Im used to jailbreaking iphones and i used to do that alot. (man its so much more complicated on android).
and im god damn stuck on the first step already.
the freaking OEM unlock option is missing??? Im into the developer mode. its not there. Now i know you have to wait 7 Days, but ive had the phone for 2 months. Is it because Ive just updated it to oreo and it reset that timer so now i have to wait seven days... (im sadly a pretty impatient person, im trying to do this at 2am instead of sleeping)
I have an international version and i know its possible. Ive got the SM-G950F Model
Please help. theres so many different guides for so many separate things and old posts and different phones and models and situations.. :c

Same problem here. BUMP!!!

I have also the same problem. my model is G955f Exynos. after flashing official Oreo Rom, CRB7, then updating that to CRE3, I can flash nothing again, not TWRP, not Cf-root, not even nougat Rom. I have tried different versions of Odin, TWRP, and Cf-root but no result. And there is also no damn OEM unlock in Developers options. Does anyone have any solution?
someone has posted here a software named "Cygwin". Its Linux tool, so hard and complicated to use for me.
If anyone can find how to use "Cygwin" to erase Nand and flash again, please reply.

Go into the settings and turn off auto-detect time. And time to transfer a month ago. Next, the developer options disable auto-update. Then go into the firmware update to disable the automatic download and click on download updates. Reboot the device and it will appear. I always do that !!!

I don't have Note 8 so I can't be sure but there's no harm with the steps I mentioned.
I actually tried to re flash it clean again(for the 2nd time) with Odin, and @altai1963's trick work again.
Why need 7 or more days when you can do this?
Just try it and let others know if it works for Note 8
Goodluck!

I don't own Note 8. I needed it for the article, it will be published on the XDA portal in a couple of minutes.

Does not work for me. Every time I reboot it shows todays date and no OEM unlock.
I go to "date and time" and set to 6 weeks ago, press done.
Disable auto update time.
Disable Auto update system
Disable download updates automatically
press download manually, get error "couldn`t download update"
reboot, and time goes back to today.
What am I doing wrong.

You just need to make sure your date doesnt revert to current date time after you reboot.
Can you try turning off the sim slot? or airplane mode(then turn wifi on)so that wifi is the only wireless connection u have.
I believe mobile data/sim network auto. adjusts ur time. Let me know if this works

Nope, same issue. Airplane mode, no sim,
could be that i have june update installed ???
I can set time forward and it stays set but going back always reverts to 26th june for some reason. not even todays date.
edit: ok, think i`ve solved it. I re-flashed stock firmware on Monday as I had "only official binaries" error, could that be why I cant go back further than a couple of days? It`s the only thing i can think of why I have this problem.

Same thing happenig to me...doesn't matter if i even turn the wifi off and take out the sim card, after reboot it shows the current date.

Any confirmation whatsoever on the Note 8? Have people seriously been so scared off by the OEM Unlock issue that no-one has bought a new one recently, lol???

Sorry I cant help u with that where DATE & TIME is not sticking after reboot.
Im not sure whats the real cause but for me, the steps / bypass for OEM Unlock option is still working to me until now.
My device is SM-G950FD Dual XTC CRED build

sign into your google account (Must do)
and sign into your Samsung account
1)- change phone date manually back 10 days
2) go to settings - software update and check for update. You should receive errors messages sometime. Don't worry. Just ignore it.
3)- restart phone. After that go to settings -checking software update (when it says your phone is up to date) immediately go to Developer Options and you should see OEM Unlock appear back. You may need to try checking software update few times to get it work.
I tried that 2 days ago and it worked

So updated to latest CRG1 firmware hoping that would bring back OEM unlock function. Well it`s been over 3 weeks since update and still no OEM unlock option available.
Has this feature gone ???? It`s bootloader 3.

proven way 4 the oem unlock to reappear:
1. remove the sim card, factory reset
2. on setup screen, log in wifi, skip gmail, skip samsung account, skip the additional apps, set the time back 1 month (twice, because s8 will try to correct the time immediately)
3. untick automatically update, then check for update manually. then restart
4. sim card still out, phone self correct time, check for update manually again, then restart.
5. sim card still out, turn on developer mode, go on developer mode, wait 5 seconds n oem unlock is there.

**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.

Sunuva....
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 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.

Do we need to factory rest or just reboot phone after we change date?

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??

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.
