Hi. I am using Samsung A5 2017 (Android 8.0) and have reset it and set up as new device. I then do the date trick hoping to show the OEM unlock option but it doesn't work. I am not sure I am do it correctly.
- Change date to previous month, turn off auto update in Developer option.
- Manual check for update so that it shows the checked date as the date I set, Restart device
- Check the OEM unlock
Someone says after reboot, i should turn on auto update. I follow this advice and check for update with automatic update setting. My phone then show available update. But still I can't see OEM option.
What can I do now if I don't want to wait for 7 days?
Does anyone have solution?
I've been in this kind of situation before
I tried to factory reset via recovery, boot the phone as normal but don't log in to the Samsung account. Then I wait for about 1 week (I'm not sure this thing is important because I only try it once) and viola the OEM unlock appear
good luck

So far the confirmed solution is this, as someone wrote in another post which I forgot and found it by trial and accidentally also. Just flashed the Australian version of the stock SM-A520F ROM (country code is XSA) via Odin. Yesterday morning I tried to flash this stock ROM after waiting for more than 2 weeks in desperation... :silly:, and voilà, suddenly the OEM unlock option shown up directly in the Developer Option setting without have to waiting for days... But I reset all settings to the factory settings since I want to flash a new custom ROM after that, I don't know if you can do it without the need of factory settings reset, you can try then... :good:
From the time I wait for OEM to be unlocked, I can tell there's no way without waiting. Be sure you guys have factory reset, log in google account (no need samsung account), check for update (to have device registered), then wait. Af thẻ 168 hrs waiting, you should close settings and re-open settings again, go checking for OEM toggle.

If you still haven't gotten the OEM toggle, try these steps. These have worked for me plenty of times:

tried that solution, didn't work
The same thing happens to me with my a520f adroid 8. wait 3 times 7 days and nothing I did factory reset wait again 7 days and nothing now flashed and I'm waiting. The trick of the date never worked for me; (
I hope someone knows the solution..

Finally, after 7 days the OEM option became available, but when I enable it forces me to reset to factory
"If OEM unlock is turned on, your phone will be reset to its factory default setting after you restart it...."
So I enable it and it reset the phone to factory setting and now again the OEM unlock is not there...
Any idea what should I do? to enable the OEM without factory reset?
you need to factory reset though as it reboots go to download mode and install TWRP and custom rom. otherwise you have to wait another 168 hours
same issue

What? Seriously? This is f*cking insane...
So, as it restarts I have to quickly force it into download mode to complete the process?
This is bananas.
Yup that's right. I went through 2 lots of 168 hours. Though now all good
Check out the twrp thread and it lists all the steps

Haven't read twrp docs, thanks for that.
Just wanted to share:
Overnight I hit my second 168 hours. I work day hours, so haven't had time to try anything yet. However, I popped into Dev Settings and OEM Unlock is not only available, but also checked with the message "Bootloader is already unlocked."
Okay, so when the automatic reset happened, it kept OEM unlock; however, RMM was still "Prenormal" so didn't show in Dev Settings. I am confused by the bootloader being unlocked message, because the Heimdall commands didn't work when I tried them last week to install TWRP (I was using the instruction on LineageOS's website).
Very interesting. I'll report the full outcome back after I get some work done this weekend.
No issues really. Followed LineageOS instructions on their site. I just had to add the BRE5 file and the fix by BlackMesa123.

SM-G965F/DS - European Exynos model.
Sorry about post a new thread about this again, but my situation seems a little weird.
I got an S9+, from Australia Optus (but I'm in China), with the latest firmware, trying to get the missing "oem unlocking" option back but failed.
In download mode, both OEM and frp is off , RMM state: prenormal.
My procedure is:
1. Reset the phone without SIM card.
2. After finishing the whole setup and get into the destop, I plug in the sim card. (but didn't login google or samsung account, because I can't connect to google service. So if I want to get through the setup, I can't plug in the sim card or connect to Wifi.)
3. Then I connect wifi and login in samsung account to restore my backup.
4. Open Developer Options.
5. Wait 7 days. (the uptime is over 168 hrs, even over 300 hrs)
6. the "oem unlocking" is still missing .
Or the phone must online "the whole" 7 days?
Because sometimes the phone will lose the network in subway.
And the swiching between network and wifi won't make a difference, right?
I've already consult the Australia samsung customer-service, can't help me online. And the Samsung Centre in China didn't have the access to fix an S9+ sold in Australia.
Hope somebody can help me to fix this, I want to install a third party ROM.
You have to reset your device while the sim card is in the device , then in the setup you have to log in to your both google and samsung accounts , then wait 7 days , and it should appear , if it doesnt appearing simply use google to check how to fix the missing OEM Unlock option

thanks! I'll try in this way.
so to clarify, whats the problem when you just leave the sim in, restore/wipe phone, login to google account, then wait 7 days and check dev options ?

The problem is Nothing Changed. OEM unlocking still missing. RMM state still prenormal. Can't do anything.

You should flash the original fw (mine is optus) and leave the phone without a sim inside, connected to wifi, on all the time. Plugging the chinese sim might not unlock it.
Hello,
I have unlocked the bootloader of my A10 and it says so when booting up. However, the OEM unlocking option in developer settings has dissapeared completely, not even appearing greyed out.
The problem is that I cannot flash TWRP because the phone says it supports only official binaries. What should I do.

How to get OEM Unlock option back?
1. Open the Settings app. Tap on General Management → Date and time.
2. Use the toggle button to disable Automatic date and time.
3. Set date option will be enabled now. Tap on it, and set the date to about 10-20 days earlier.
4. Enable developer options.
4.a Go to your device Settings.
4.b Select ‘About phone’ » tap seven times on ‘Build number’.
└ This will enable Developer options under Settings.
4.c Go back to Settings » scroll down to the bottom and you’ll see Developer options menu.
5. Open developer options (in the Settings app itself), and find the option called ‘Auto update system‘. Use the toggle button to disable it.
6. Now, go back to the main screen of Setting, and then tap on Software update.
7. Disable the option ‘Download updates automatically‘.
8. Tap on ‘Download updates manually‘ option, but it will give you an error because of the wrong date, so it’s fine.
9. Restart the device.
10. Go to Settings > Developer options. The OEM unlock option should be enabled now.

Is what you did?
Otherwise you can try like this:
1. Disable Automatic date and time and set the date back 10 days
2. Restart the phone
3. Set the automatic date, if you are connected to a network, or manually reset it to the correct date
4. Restart the phone
Or you can wait a week and the OEM Unlocking options reappears

You have no problem bro, OEM might be hidden but it's stiched on. Even if you factory reset it it will remain the same. If you insist in finding it, Download a software update or press check for updates then quickly toggle your OEM
I got the device today, but OEM Unlock is missing from Developer Settings. I tried the date and time hack, but it didn't work. I put it 15 days back. Then a month back. Then I put it to the earliest possible date, January of 2004. When I reboot the device, OEM Unlock still does not show up.
How do I get past this? I can't even proceed to anything without activating OEM Unlock.
T220, OEM Unlock won't show up even after date trick.
Ok I got OEM Unlock to show up. Follow these instructions EXACTLY.
Factory Reset Device (Sorry but this will happen when you unlock anyway, and has to be done first.)
Skip everything on the first boot setup including WiFi settings (you'll connect to the Internet later).
I did nothing else, didn't even enable dark theme.
Enable developer options and disable automatic system updates from there.
Connect to a WiFi network.
DISCONNECT from internet after a few seconds. You'll see it trying to update things in the pull down menu, disconnect from internet, you don't want it to update anything. It just needs to be connected long enough to update the day and time to the correct day and time, and register your device. If it didn't work, it didn't register your device yet.
For me, it did get to the point where there was a notification that said, "Finish setting up your Tab A7 Lite." DO NOT finish setting anything up, but do make sure internet is disconnected. Ignore notification, but you should see that.
Disable automatic software update. Settings > Software Update > turn off.
Go to General > Date and Time settings and select for the time to be set manually (don't touch time zone). Set the date to be EXACTLY 10 days BEHIND from your current date.
Go to Developer Options, and OEM Unlock should be there!
If it still doesn't work, you may have to go to extreme measures, but I didn't have to. But first just make sure you did the above steps EXACTLY.
Go here for extreme measures if you did EXACTLY like above and still didn't work (my instructions above were a bit different) https://forum.xda-developers.com/t/a7-2017-w-binary-9-rmm-state-unlock.4057831/post-82049513

Does this technique work for any T220 in any region? I'm thinking about getting the T220, but I read in another post by @tom.android that Samsung doesn't allow OEM Unlock in North America.
Update - Can confirm that this works! Thanks xbt-!
Hello recently I tried to root my phone, wanting to fix ghost touch, I did something wrong and the phone stopped working, "Only official binary blah blah blah ..." popped up during startup, I decided to reinstall the official stock, the phone started working normally, even ghost touch repaired, I looked at the Root Checker application if I have root, it turned out not, which is all right, but when I want to add the card to google pay or open McDonald's applications, I get a message that the phone is rooted or was somehow rooted modified, what can I do in such a situation, please help me, I tried to install other stocks from other operators and restore the phone to factory settings: _ (
I saw one solution, probably in this forum where someone wrote to enable OEM Unlock and USB Debugging then disable and enable again, something like this, but I don't see OEM Unlock in the developer option, I know that with a failed root attempt, I somehow unlocked this option, but I don't remember how and I prefer someone to help me as best as he can, because I don't want to break anything anymore, I just want Google Pay to start working for me
OEM is probably hidden cause your device isnt older than 7 days. Connect to wifi and enable automatic time and date, than disable once done set the date atleast 7 day forward and oem should appear but you will have to lock ur bootloader before you disable oem and if you are running a custom firmawre make sure to backup data if you wanna go to normal firmware
But I use official firmware from some Samsung firmware site, i think my bootloader is locked, anyway do you have any solves to make work google pay?
I tried to unlock OEM but this solution with data & time doesn't work for me.
Hey, when I go to Google Play Shop there is an information that my device isn't certified, I tried to register my ID Device and still doesn't work can It be a problem, because of that Google Pay doesn't work?

If i wait 7 days OEM option should unlock automatically?
Is it good idea to root this device correctly and use magisk to make google pay work good or for example root this device and then unroot to make work google pay?

before you do this if odin says you are in custom mode backup all your data before doing this. no it wont automatically, first you have to go to odin mode and hold up for a bit until the screen shuts and shows the question (do you wanna lock your bootloader) you select yes once done if you are on custom it will bring up only odin mode before anything thats where u flash firmware, now that should get rid of the root, and then if u wanna disable oem connect to wifi disconnect date and time unselect automatically and go 7 days ahead and the option will appear.
How to check if i have custom mode and what i have to hold up?? please explain better because i don't know what i have to do
