Bootloader Unlock (Developer Option Bug) - Nokia 5 Guides, News, & Discussion

Hi. Today I found a bug in my Nokia 5 allowing me to enable OEM Unlock in the Developer Option Settings. Please note that I am on the new Android Pie with the latest April security patch. So here is what I did:
1. Please enable Developer Option on the Settings menu. If you already did so, skip this.
2. Now, on the Developer Option, you can see the OEM Unlock is greyed out. To toggle the switch on, "you need to disable and re-enable the Developer Option toggle switch at the top of the menu".
3. After then, you can now freely toggle the OEM Unlock switch. You will be prompted then to enter your device password and voila! OEM Unlock is now enable.
4. To switch it off, you just need to do the steps over again.
That's all. I hope this helps. Sorry, I might have posted this in the wrong section cause I am a new member and just wanted to fill my share to you.

Hey there! been lurking xda for ages but your post just made me register! Thanks a lot for sharing mate.
I just downloaded the update and tried this method, worked fine. Btw there's a new security patch as latest update (5/19), didnt bother doing it as they could have patched it probably.
So, i tried flashing twrp and noticed it still wouldn't let me and flashing get_unlock_ability returns 0. Did you manage to get past this?

This actually works. Havent flashed anything yet, as I'm scared of bricking it.
I just love the good old days when I had the Tmobile G2x with the Nvidia chip, flashed the darn thing so many times, even bricked it numerous times, but I was able to go into recovery and reflash it again. That phone was "Flash and Brick Proof"

thanks for sharing, spent countless hours trying to fix with usb driver setups and cmd lines from other tutorials.
question is what's next?

That's a dummy command,
You still need to properly Unlock it, I'm afraid all the options are paid service

This thing still works as now it's may 11th 2020.
I'm I ready to unlock bootloader now?

OEM Unlock is on... but returns as "disabled"

I had to get a new Nexus because I lost my previous one. Now I'm trying to root this one but I can't seem to get the OEM Unlock setting to work. I've rebooted it, factory reset it, enabled/disabled the option countless times, enabled/disabled USB debugging... nothing. Google doesn't seem to have an answer either. Anyone has any idea what's going on? Or if there's another way to unlock this setting?
Thanks for your time!
Just to clarify, are you actually attemping to unlock it? You have to first enable that option in developer settings, but you still have to put the phone in bootloader mode and run the command "fastboot oem unlock", then use the buttons on the phone to confirm it. I think all your data wipes first time you unlock your bootloader too so just be careful.

Depending the Android build installed, sometimes the option has been greyed out. Don't know why...
You said you tried to get the "OEM unlock" slider working... But did you try issuing the unlock command in bootloader?
Good luck...
Yeah, I'm aware it wipes your device. Also, don't burn me but I was using a Toolkit to start the process but I just gave up and did it the old fashioned way. After restarting into bootloader and sending the fastboot command it prompted the question to unlock it, so everything went smoothly.
Somewhere I had read that Android purposely locks OEM unlocking after n reboots, and I thought I was completely out of luck, but everything went smoothly. Thanks for your time!

[Exynos] Questions concering OEM Unlock

-This is probably going to be confusing and a bit all over the place, bear with me.-
So, I bought my N8 back in November and directly went in to the dev options and saw OEM Unlock was available.
Now I didn't bother with it and now recently I've been thinking about rooting it, the catch is I've seen countless threads claiming a notorious "RMM"-lock taking place and putting devices in to "Jail".
Here's the sketchy bit:
- I rebooted and checked in DL-Mode and saw no particular line referencing RMM. Then after some reading got buildprop editor and checked what the "ro.security.vaultkeeper.feature" status was; It's 1.
- Rebooted again, double checked and no RMM entry.
- Enabled OEM Unlock and rebooted about 3-6 times (no flashing done) and it booted up fine with the OEM Unlock setting still enabled and present.
- DL Mode still does NOT show any RMM message or line, just "OEM lock" and "FRP lock" are off.
Am I missing some information as to how the "Jail" is triggered or does flashing only trigger the "Jail"?
BTW, here's info on my device:
- N950F, unlocked, Germany
- On latest January Patch, N950FXXU3BRA2
- Non-branded, but marked as DBT

You unlock the toggle and flash twrp, etc., then when you boot back up you must ensure the i.e. unlock is toggled on (or else toggle it). Otherwise you'll end up in jail when you reboot again, since you flashed custom and didn't unlock OEM before the new reboot.
This question could have been asked in the oem unlock thread too

Alright, I'll check that and see if i'm also in the boat.
Odd enough that it toggles itself off automaticallly, that is wondering me.
Weird.

Yep, just as I suspected; Your idea didn't apply @sefrcoko .
I installed TWRP, Magisk, the no-dmverity (in that order) and booted perfectly fine with the following result:
- Dev options were hidden since DATA was formatted
- After opening Dev options the OEM Unlock was still switched on.
That has me thinking if it is either sw or hw related, that some devices lock-up.

You asked what jail was, and I explained it... You're just not in jail. Not every device is affected, and fixes to prevent the issue are being baked into custom roms and .zips now too. Lots of factors at play, hence the monster OEM Unlock thread . RMM seems to be the culprit.

General What not to do with China ROM

I recently got the phone and i have the China version 12/256. Here are few things to take care:
1) Install Google Keyboard first before debloating system apps using adb.
2) Very Important: First update the phone to latest firmware (12.0.13) before you toggle the OEM Unlocking option in developer settings. If you dont update first and have the option toggled and try to install an OTA update the phone will just bootloop unless you clear the data and sign in with mi account again. This will reset the 168 hours time in the software. So always update the phone to latest update.
3) If you are using google pay, go to nfc settings and change the wallet from Mi Wallet to HCE Wallet.
4) The stock TPU cover is loose on the sides. I dont know if its just mine. But better buy another case from aliexpress.
5) DO NOT install global stock rom through fastboot or mi flash tool. It just wont work because of the different versions(regional) of phone. Only install xiaomi.eu ROM using the guide from a post on xda because the install script knows which version your phone is and installs the appropriate system files.
@ingbrzy can you confirm that? :

It is safe to install. haven't installed it yet but read on forums that it is working.
so I guess
1) unbox your phone
2)update to latest software via settings.
3)factory reset device after that.
3)request bootloader unlock.
4) after 7 days, unlock your bootloader and tooggle that OEM unlock
5)follow instructions on xiaomiEU rom.
is that safe enough? Lmao

6) Find EDL support near you

1) Update to 12.0.13
2) Sign in to MI Account on device if haven't done yet.
3) Enable Developer settings, Developer Settings> Toggle OEM Unlocking
4) Turn off Wifi, Turn on Mobile Data, Settings> Additional Setting>Developer Settings> Mi Unlock Status> Click Add Account and Device.
5) Download Mi Unlock Tool, Login to same mi account > Turn off device, Hold Volume Down and Power Button ( you will see fastboot screen)> connect the device using USB, You will see the device, Click on Unlock button.
6) It will show wait for 168 hours to unlock.
7)Do not sign out/ change mi account on device or toggle the OEM Unlocking option. If you do you have to start from the beginning.
If you dont see your device in Mi Unlock tool install adb and fastboot drivers.

My friend doesn’t matter how long it takes to boot up.....as long as you not in fastboot after restart
It seems to be working fine but I need to go outside and test the 5G and 4G signals are still as good as before
It's definitely feels much lighter and smoother
WhatsApp notifications are working properly
There's much less apps in the drawer, Chinese was very bloated , now there's not a Chinese app or character to be found!
Also banking apps are working fine!

Please post the instruction how u did it. With full info
Just downloaded and install it from a Windows laptop
You have to wait 168 hours to unlock it and then open the phone in Chinese language to get to the developer options again before you flash , you need to enable usb debugging again!!!
You will need wi-fi to get back in because there's a security check after unlock, it maybe in Chinese but you will figure it out
I had never used a Xiaomi phone before this one , there are literally no downsides anymore....
I'll update if I can find something that doesn't work

Can you explain the technical reason and the source of the information when you claim that you must update to 12.0.13 before toggling OEM unlock.
I started my unlock last week and I have 12 hours left. 12.0.13 was not out last week. So, obviously I toggled it before that.
Can you explain why 12.0.13 specifically is required before toggling OEM unlock?

Because my phone went into bootloop. I updated to 12.0.10 and then toggled the OEM Unlocking. While i was waiting for 168 hours, i got 12.0.13 OTA update and i tried installing it. Phone restarted 3-4 times and took me to recovery. I then wiped data and it started again with a factory reset. So iam just warning people to get the latest update before doing this. Also, i do own a POCO F2 Pro and i am quite experienced with flashing ROMS. Developers always ask you to update to latest firmware before flashing as the new ROMs are based on latest firmware.
Xiaomi.eu is not a custom AOSP ROM but just a word of caution.
Sounds like after OTA 12.0.13 phone should be a factory reset it

The toggle is nonsense
I toggled mine on and off a few times yesterday waiting for update 12.0.13 when I was on 12.0.10
It still unlocked like a charm today

Question Boot loader unlock help

Good day to you all
I have recently bought myself this lovely device, unfortunately mine came as a single sim model from my network provider.
I have tried following the guide for unlocking in the "How to" section, but I fail to get passed the point where one must check the Mi-Unlock status of the device.
If anybody can help me with this I would be grateful.
Thanks in advance
This Is the result i get from the unlock tool
Ok so I have found my problem.
I worked out that Find Device setting was enabled and was blocking the Unlock procedure.
I disabled it and tried unlocking again. This time I got the wait 168 hours to try again message.
Progress!!!
I hope this can help somebody else that is having the same issue
Can you tell me the steps you used in unlocking your note 10 pro bootloader ,I still don't understand how to do it well
Disable Find my Phone, Enable developer options, enable OEM unlock and Check MiUnlock status in developer options.
Download MiUnlock tool from Xiaomi website, do not use 3rd part website. Install it onto any pc and check for updates. You will need a Mi Account for this. Use these same credentials to log into the Mi Account on the device before the next step.
Enable USB debugging in developer options and reboot to bootloader. Connect the phone to the pc and start MiUnlock tool. Follow the prompts till the unlock process fails. The tool will give you a message to wait 168 hours before trying again. Do not reboot your phone during this time. This is 7 days wait. Use this time to back up your phone and save any data you need from the phone.
This is where I have got up to so far. Another 6 days to go.

You're using older unlock tool. Get new one from official website.
Update check was done inside the app and official latest release downloaded.
I will recheck this weekend for newer version.
Thank you
Sorry for late reply.

Hello, I recently got this amazing phone and was thinking about unlocking the bootloader and flashing Magisk.
How do I find out my remaining time left for unlocking the bootloader? I feel like I could unlock right now because I could bind my account to my phone straight away, although I might be just dumb and it gets binded immediately. Thanks.
Xiaomi tool.
USB debugging enabled
Accounts: add a MiAccount.
Disable Find My device * very important* otherwise bootloader unlock is blocked.
It takes 7 days. Do not reboot or power down the device for this time. Unlocking is done twice. 1 to start the countdown and 2nd to complete the unlock.
Search the forum for instructions on unlock process.
You can check your unlock status in developer options. If prompted use your MiAccount credentials.

normally I'd say you have zero chance to unlock, however I recently saw this on telegram and I'm curious if it works...
"US/Canada devices has no oem unlock toggle!
How to get OEM Unlock option back for Non US/Canada device?
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."

Returned SM-G781W (Canada) model today back to the **** hole factory it came from.
I tried the above steps and DO NOT work, they also come shipped with BL 3 or something and 0 chance of rooting, if they DO happen to come with BL 1/2 then you root I think.

Thank's 3Mel .. your align my research
Ok for Canadian model is the chipset on the motherboard of the phone are not the shame as anywhere because it's sale whit sim unlock by default for XAC version ... the difference is physical
