Stuck on 7 day waiting on OEM Unlock. How to rollback rom with option? - Samsung Galaxy S8+ Questions & Answers

I came from android nougat on my galaxy s8+, however, I wanted to update to oreo, so I flashed it through odin with all the necessary firmware files. I configured it all once after. However, OEM Unlock is missing from the developer options. I've read that you have to wait 7 days for it to appear but I don't have the time to wait as I have some projects to deal with. I'm wondering if I can dirty flash an old rom over stock rom to enable oem unlock through odin since I can't flash through twrp . Once I get the regular rom loaded, I'm going to flash twrp and find a custom rom based off oreo instead. Would be great if someone knows any work around for this.

New in MI4C

Hello everyone.
I live in Brazil and I bought at the Aliexpress MI4C Xiaomi. I haven't received it yet, but I've already started researching ways to use it with another ROM than the original. The seller sends the device with google apps and multilanguage option. So, he makes some modification in the ROM, and says to not update the ROM officially on Xiaomi servers.
I see a lot of complaints about the Chinese bloatwares in ROM and so I wanted to install one that was good, but nothing with applications in Chinese or unnecessary ones.
My question is: in this case the bootloader is already unlocked?
In the meantime, I sent my request for unlocking bootloader to Xiaomi and received the SMS containing a link. As soon as I get the cellphone I intend to do the procedure. There is a risk of bricking the phone?
I’ll do appreciate good links with how-to and good ROM to daily use.
Thank you.
The seller shipping a modified ROM and telling you not to update the official would suggest your bootloader will not be locked. For now only flashing the latest official China dev builds will lock your bootloader.
Getting pre-approved for unlocking couldn't hurt though I guess.. just in case. You might need to have a working Xiaomi framework in your ROM to register your phone once though. If your ROM does not have the xiaomi services, I would suggest either Xiaomi.eu or sMiUI as a ROM, both are pretty much stock MIUI with some chinese bloat trimmed.
But most likely you will not need to unlock your bootloader anyway. You will need to check your bootloader through adb anyway before doing the steps to flashing a new ROM. You will best be flashing your recovery through adb, the instructions can be found through most ROM pages or simply searching TWRP Mi 4C. The command to check if it's unlocked is
Code:
fastboot oem device-info
A very extensive directory can be found in the INDEX thread, first in this forum.

you cannot check the bootloader locked or not by that way. My phone when checking this, gets the input "bootloader unlocked: false" but I can flash other recovery freely.
in his case, he is using a modified rom, it means his bootloader is not yet unlocked. Right now, if he wants to come back to chinese rom, he should use Mi flash to flash his phone. If he wants other rom like CM13, he should download the latest TWRP and the rom, put the rom into his phone storage. Then try to go to fastboot to flash the recovery, then go to the recovery and flash the rom.

Ah, that might be incorrectly reporting indeed. In any case when trying to flash recovery, if you're locked it'll simply fail and won't be harmful.
But why would you think his bootloader is not unlocked? If he's using a modified rom, it was probably flashed through fastboot or a custom recovery, both require the bootloader to be unlocked.
But even if he was not on a modified rom, stock Mi 4c have always come bootloader unlocked. Someone would have to have gone out of their way to lock the bootloader and I doubt any reseller would do that, they would risk a lot of refunds from angry customers.
I strongly advise against using miflash to flash any official rom unless you have no choice, since then there's a chance you WILL lock your bootloader. For now only dev builds are locking it, but the next stable release might very well too.
The first step should be to flash TWRP
The second step to stay away from Official China build
The third step to keep away from Official China build
The fourth st...
^ sorry my bad.... I was not focused. Actually I mean his bootloader is unlocked .
The safest way is flashing via computer, using mi flash or flash twrp image. You are right
1. Ur phone not lock bootloader
2. U can flash custom recovery...(TWRP)
3. "MUST" Stay away from official MIUI ROM
4. Flash whatever u want...sMiui, CM13, etc,etc
5. Remember Point No.3
***Btw, download official Fastboot ROM and keep it to ur drive, for just in case if u want to sell it again
Hello. Thank you all. I just received my phone. Great, btw. I'll read again and again all instructions and try. Thanks again!

Even as a last resort to getting your phone working if you did something wrong, please don't install the newer official roms, it's the mistake I did this weekend now I have a locked phone with a rom that has force-closes everywhere and absolutely no way back.

Don't flash the latest chinese rom.
No.
The only scenario where you would want to use miflash to flash a chinese rom would be as a last resort to flash the fastboot version of V7.1.6.0.LXKCNCK to restore your phone. Any later version will lock your bootloader.
If you don't care about locking your bootloader and the arduous process of unlocking it, you're easier off just taking all the latest updates OTA via the updater.
Hello everyone. Thanks for the help. In fact my bootloader was unlocked. I flashed twrp 3.0.0.3 and flashed the CM13 teamluminial, Android 6.0.1. Excellent. Thank you.
Hi!
Same scenario here..
I will receive Mi 4c with the Bootloader Unlocked, Rooted and the Multilanguage ROM.
But I have already received from Xiaomi after my request also the number for the official unlock procedure but now I'm a bit confused..
Do I have to unlock the bootloader once and for good with the official way?
Because I've read that the unofficial way isn't so secure in long term.
Do I have to install from the Updater the latest Cina Dev ROM and after that to proceed with the official unlock? Or it is better to use the Fastboot ROM?
Please could some one tell me in any case what to do ?
Thanks !
If you don't flash something that will lock your BL, no need to Unlock.
Ok first I must check the status of the bootloader to be sure that it is unlocked (via cmd control or cpu-z)
And after that can I choose an unofficial weekly miui.eu international ROM and install it?
Can I download and also update every week via Updater this ROM without issues?
At the moment my problem with flashing is that I don't have my pc (the one I have now runs win xp) and I don't want to stuck with the eventually malware or fully spammed modified rom of the reseller..
Which options do I have?

Back to Miui official ROM

Hi.
I'm right now on TS CM 13.1 and I want to try the RR. But I didn't unlock the bootloader officially, so I need to do it properly now so I won't end with an locked bootloader.
While I'm waiting for the approval... can I just flash the latest China dev ROM with my current recovery? Or should I flash it from fastboot?
Thank you.
Since you have a custom recovery, try Xiaomi.eu or miGlobe, though be careful as I think latest versions (Android 7) will lock the bootloader. To be safe, I'd flash an older version with Android 5.1 for now.
You can't try RR 5.8.1 based on Android 7.1 as it requires lollipop bootloader.
Or you can flash 6.12.22 and then update to any Nougat Miui Rom available on Xiaomi.eu. This is done via Updater app.
Sent from my Mi-4c using Tapatalk
I didn't realise there was a previous RR version with lollipop bootloader.
I already got the SMS with the approval from Xiaomi. I though it would take long. So, if get that right, I should first flash an older Android 5.1.1 Dev ROM and than update it with the Updater app to the latest version with 7.1 . This will lock the bootloader and than I can unlock it officially.
If I do it from from fastboot I can flash directly the latest 7.1 dev ROM, right?
Thank you guys. I always messed around with ROM's with my old GNex, but this Miui stuff confuses me a bit.
No need. Just go in TWRP and see the RR N thread there is a link to nougat blobs. Install that and then install newer TWRP that works with nougat (see android development). I think at this point you'd have to unlock bootloader. Then install room normally
But, as I read in the RR N thread, after I flash those blobs I'll end up with a locked bootloader if I previously unlocked it unofficially. As I did.
And, at least I think, I can only unlock it again from an official ROM. That's why I want to flash Miui.

Whether you have unlocked your device officially or not, it will still lock your bootloader. The key here is if you have the permission to unlock it. If not, then don't proceed. You can officially unlock your bootloader after 5 business days upon receiving the SMS.
Ok. I do have the permission. And can I unlock the bootloader right away with mi flash unlock on a custom ROM or do I need the official miui ROM?
Worked for me with no OS, so I assume you do not need miui.

After you flash the blobs, the bootloader will be locked. Unlock it via Mi Flash. Then flash a Nougat compatible TWRP and you're good to go in flashing Nougat RR.

Can Oreo android 8 firmware be rooted on s8 exynos? G955FXXU1CRAP

HI Guys, I have installed the G955FXXU1CRAP at my s8+ but when I try to flash twrp with odin it get status fail and the phone says that installation of custom binaries are not allow (OEM LOCK and RMM STATE: PRENORMAL).
Did you tryed to install Twrp and root G955FXXU1CRAP? How you solve this bootloader lock?.
thanks in advance.
Alex.
In order to root you have to flash TWRP and for that OEM must be unlocked. You have to wait 7 days with the phone on (without reseting) to get capable of unlock OEM in developer options, due to a new security issue with Samsung.
I'm in the same situation. 4 days and 10 hours left.
This has been said a bunch of times throughout the S8 Plus threads - but I will give it to you again.
your phone is locked - y ou will not be able to flash anything until you pass the 168 hour (7 day) period. When you do get to that point, you can flash twrp, root and or flash a custom rom. Whatver you do, before you reboot your phone, flash the file you find at this thread: https://forum.xda-developers.com/showpost.php?p=75360965&postcount=22 It will make it so you don't have to do that again. Your phone will not get locked again and the RMM State will be NORMAL - instead of Pre-normal.
That is the only thing you can do. And it is important to remmeber to flash the RMM Fix before you reboot (after flashing twrp, SuperSU/Magisk and or a Custom Rom. If you don't flash that file yoiu will be very likely locked again for another 7 days as soon as you reboot.
The link above has a much better explanation but I hope this helps you and anyone else reading this that has the same problem.
Good Luck. (I have been waiting for 4 days so far - I have three days to go -
Well, thank you so much for that information guys. I did not know it.

Could you please be more detailed on the steps I should take for not being locked again?
I'm about to flash Oreo and I want to flash TWRP and Magisk manager after those 7 days but I don't know in what order I should do it all, when I have to flash that RMM aswell.

Take a look at this screenshot though. I installed the CRAP build less than a day ago and when I first went into developer options, OEM unlock was already enabled. I'm REALLY confused right now..

Not sure if you know the answer to this but do we have to flash this every time we reboot on a custom ROM or flash this every time we flash a custom ROM?

Go into download mode (Power, Bixby and Vol Down) when you are in download mode, you can see what the RMM State is - it will either say NORMAL or PRE-NORMAL.
If yours says NORMAL - then you go can go ahead and flash TWRP via ODIN. If you are having flash issues at this point, ask in the TWRP Thread and you should be able to get some help.
However, if you are PRE-NORMAL in download mode, then you are locked and won't be able to flash anything until you pass the 7 day period.I think the 7 days begins on the date you flashed your current firmware.
YOu can be in PRE-NORMAL and still see OEM UNLOCK. BUT if you are pre-normal and you see OEM UNLOCK you cannot flash until your RMM State changes to NORMAL.
I hope that helps.

Yes, the RMM Fix must be flashed after you flash TWRP or after you flash a custom rom, everytime. UNLESS the rom has the RMM Fix baked into the rom - some do - some may not. Won't hurt to fllash it just in case, everytime.
Thanks again for the rapid response but, I'm identifying an issue with the storage on this firmware g955fxxu1crap. My phone exynos g955f has 64 gb of internal storage, but after this upgrade it shows only 16 gb of internal storage.
Did get this same error , how you solve it?
thanks in advance.

What happened after your seven days were you able to flash twrp and stay rooted in Oreo with Oreo bootloader and modem? Have you tried flashing the new Oreo Bl & Modem? Curious if the seven days is going to be mandatory for people with new phones that want to root them on Oreo.

After 7 days I could perfectly flash TWRP and root, no big deal. If you go into download mode and see RMM STATE: PRENORMAL then you can't flash. I guess all new phones with 8.0 since January are pre-normal, but I'm not sure.
Ive seen in the other thread that you could flash the entire nougat stock rom (nov 2017 perhaps) which will allow you to bypass the rmm and then flash TWRP and custom ROM? Could anyone confirm this workaround?

How to install Oreo ROM?

Hi! I'm really humbly sorry, I'm new to this stuff, so I have to ask you...
I have a Galaxy S8+ Duos (SM-GD955FD). I bricked it once or twice trying to root it. So I had to flash a sammobile.com ROM...
Now this is done, I have a successfully rooted phone with with the Baseband version G955FXU1AQH3 and the irritating "security notice" (since I was not able to install Magisk, and the NotifyClean app doesn't work either).
I would like to flash the latest Oreo and root it. I also heard good things about the Oreo ROM by alexega.
So: I'm on AQH3 rooted. What can I do?
Thank you for your patience.
If wou want to install stock ROM you must follow this instructions: https://forum.xda-developers.com/galaxy-s8+/how-to/guide-how-to-flash-crap-using-odin-t3748555. Bear in mind that if you install stock due to security issues you can't unlock OEM for 7 days after flashing (you must not reboot your phone for 170 hours).
If wou want to flash a custom rom you must have TWRP installed, move the zip rom to your SD card and just flash it from recovery. Make sure to format data before flashing.

Nice, thank you. So I have just flashed the thing with the sammobile.com ROM again (so, no root) and updated to the oroginal firmware Oreo following your link (I worked parallel).
I was just about to root Oreo and was googling for a way... But did I get you right? I should not reboot my phone for 170 hours now?!? So, no rooting until next week?!
Edit: I have developer options enabled and the "OEM unlock" switch is on (it says: "Bootloader is already unlocked.""). So... confusion...

Excuse me, are you currently on Nougat 7.0? If so, you obviously have OEM unlock option available. The problem is in the new 8.0 stock rom, wich sets RMM state to pre-normal preventing you to flash TWRP and to get root in OREO. To skip that you can directly flash a custom rom with 8.0.- Otherwise (stock rom) you must wait 7 days with no phone reboot to get ridd of that pre-normal issue and then flash TWRP and flash Magisk.
Just rooted the new Oreo ROM with TWRP. Works just fine, thank you.
So, what are the advantages of the Oreo ROM by alexega compared to XXU1CRAP?

There's no need to have a custom rom, if you flash the fix in stock RMM lock gets killed everytime.

First you have to install OREO and wait 7 days without reseting your phone. After 170 hours, you get OEM unlock in developer options and you will be able to flasf TWRP. After flashing TWRP you flash RMM-State_Bypass_Mesa and that´s all.

Can only install official binaries message when flashing TWRP with Odin3 on A750FN U4

Hi, I'm having a lot of trouble trying to install a custom recovery. I had it working a couple months back but wanted to go with official again for dumb reasons and now i want to go back but it won't let me flash TWRP, i can't find a TWRP specifically for this version either. It's Android 10 with March security patch.
I hope someone can help me.
Thanks.
Please only create one thread per topic. I've removed the duplicate thread you started on this topic.
As far as your issue goes, I don't actually know much about Samsung specifics, but I believe that particular message means you haven't unlocked your bootloader. You'll need to do that before you can flash custom stuff.

Like I said, I'm not 100% on Samsung shenannigans, but have you checked to verify that you didn't lock the bootloader as a part of flashing the stock firmware?
OEM unlock toggle in Developer's Options
Hi ¡...
1. You have to reinstall via odin the latest version 9 (AP, BL...etc)
2. On reboot do the entire TWPR flashing process for android 9
The current problem is that there is no TWPR for android 10.
Cheers
