OEM Unlock doesn't work anymore? - Samsung Galaxy S8+ Questions & Answers

Hey Guys! I'm pretty new to all of this and im looking for an answer to a problem that occured to my s8+ 2 days ago.
I've never had any problems with my phone. I've flashed nearly everything and have always been able to fix it if there has been any problems but now i've got a questionmark on my head.. My phone i bought in denmark and i live in sweden and 2 days ago i went to denmark with my friends. After i came back to sweden i flashed the latest update of the custom rom i am using which is GoogleWiz and after that i enabled developer options and it turns out i cant turn on oem unlock anymore? This has never been a problem before, its always been on but now its greyed out and cant be turned on. Luckily i have TWRP installed and can still flash things but there seems to be a problem cause when i turn on developer option my phones settings change and the phone turns really slow... I tried reflashing rom without turning on developer options afterwards and then the phone works fine but i want to be able to turn of developer options on for options like usb debugging, oem and so on..
I haven't checked but i guess bootloader is locked cause i cant turn on Oem unlock?
Would appreciate help with this if anyone got a solution?
The phone is rooted with magisk and has TWRP 3.2.1.0 installed.

After factory reset and initial boot you have a minute before demo mode kicks in. Head into developer options, check the oem unlock option and USB debugging. Then you are good to go, unlock bootloader, root and run sunshine to gain s-off, change cid and flash ruu to be stock

OEM unlock on Galaxy S8+ Oreo question

Hello,
I've read quite a bit about rooting on the new Oreo firmware and having to wait a week before you can enable the OEM unlock, meaning you wont be able to flash anything yet.
However, when I went into developer options RIGHT after I flashed the CRAP build, OEM unlock was already enabled (as shown in the screenshot). Would this indicate that I can go ahead and flash TWRP/magisk to root already?
Thanks in advance,
Cyborg.

You should be fine. If you go into download mode and see RMM State Prenormal then you've been locked out from flashing anything.

Yeah I didn't see anything like that in download mode so I just went F it and I managed to flash TWRP and magisk. Just to be sure though, I did flash the RMM state fix.
I still don't quite get why my OEM was unlocked when all the other people's got theirs locked. Any ideas?

It doesn't appear you are in developer options but, rather, About Phone, Status.
I know I'm not in the developer option, the screenshot is so you can see that it's already 7 days (168 hours) and even in the developer option it does not show me the oem unlock option
I show you

Google repair shop re-locked my bootloader... wtf now?

OG Pixel from Verizon, had it for years, battery has been really ****ty lately. So I had to send my phone in to get a new battery, and the cost was similar to go thru google store, so I did. Wiped the phone, restored to stock android, but left bootloader unlocked. Got the phone back today and version of android was downgraded and bootloader was locked.
How ****ed am I and what are my recourses? Tried google support, they're nearly useless.
If you never booted the device yet you can try "fastboot flashing unlock" and it will just re-unlock. Other than that I don't think you will ever see a unlock status on that phone. This is why I do my repairs myself.
Fastboot flashing unlock was unsuccessful, but I suspect that was because the phone was booted up for "troubleshooting" with Google "support."
I assume then there's no way to return it to the post-flash pre-boot state without some closely guarded hardware and software?
Before updating in any way... Search Verizon unlock Pixel and see if that process will unlock. If you allow update past a certain level stuck with no options then if Verizon locked.
Oh, would never allow an update. I'm not crazy. Tried the unlock method with uninstalling the phone app before you get internet access the day I got it, still no dice. Thanks tho.
I just did a credit card chargeback as they sent me back my device in an unusable condition and refused to compensate for it. We'll see how it shakes out in a few weeks probably. Bought a refurb Pixel 3 in the meantime and it was already unlocked, so all is well.
Thanks for the replies though.

Can you tell me what security patch you are on? If you are somewhere around Android 9 patch (potentially Android 10 early patches) you can re-unlock. If you try ticking the OEM unlock option in Dev options or if i heard correctly the phone wont boot? If you know your exact version you can try flashing it through recovery, or trying "fastboot unlock" after ticking the oem unlock. Also remember those old workarounds of removing android.phone and such? Yeah try those. Good luck. We'll try and get you unlocked again.

How to get missing developer option for OEM Unlock (unlock bootloader)?

I have an old Samsung J3 Eclipse (SM-J327V) that has no OEM Unlock in Developer Options. The phone is approximately 5 years old. I would like to unlock the bootloader on it. I'v tried the suggestions listed on the forum, but they are for new phones to bypass the 7 day waiting period and enable the OEM unlock. I tried them anyway, and they don't work on my J3.
Seems to me that I read that Samsung started hiding the OEM Unlock with Android version 8.0
I was thinking of loading some old version of the official firmware that was Android 7.0 or earlier (if I can find it). Then, hopefully there would be an OEM Unlock that would enable me to unlock the boot loader. Once unlocked, I could flash back to Android 8.1 (newest version for this old device). Would that work? Can you use Odin to downgrade the version of Android?
Comments welcome from all. Thanks!
I've tried following every youtube video and posting on the internet for how to get the hidden OEM unlock back into developer options. None of them work. I swear I have done the process of date resetting dozens of times and it still doesn't work.
Can anybody help? Please! I'd really like to unlock the bootloader. Is there any other way to do this?

Network locked after android 12 update mototorola g pure xt2163-4

Hi guys. So i bought a motorola g pure, xt2163-4 pvt1 with universal software. About 1 year ago from facebook. Phone looked new and it was "factory unlocked" However last night i had an android 12 update, wich i did, but now after the update, my network is locked. And the built in unlock tool at about phone-device unlock, wont seem to work, i get (SERVER COMMUNICATION ERROR CODE=200 MSG=SERVER_NO_CONTENT).
Isaw a couple of fixes on google, however they are for diferent divices and old, i was wondering if anyone here has a solution for this problem. I really apreciate the help. Thanks for reading.
I have the same issue but I don't have an unlocking app or was unlocked via server. Worked fine for months until after the Android 12 update.
ok so ima post a soultion that worked for me. My phone was unlocked via global unlocked, is just a gues, why? well last night i was about to unlock it with global unlock, downloaded the software, hoocked my phone, place my phone in fassboot, conected my pphone to the app, just to chekit it, i did not had any credits to use that unlock option, after reboot, phone was unlocked againg. so you might wanna give it a try. i even wipe the phone to see if the unlocked was ok after factory reset, and it was. so hope this works for someone else.
