Keep the device powered on for at least 7 days, with the device connected to a data network the whole time. After that, the OEM unlock option should appear in developer options.

There is a trick where you change the date to a month behind or a month ahead then reboot the device.
Another method involves using TWRP to flash a file that bypasses it.

Refurbished device with unlocked bootloader, safe ? help please

Hello,
I've just bought a refurbished device on amazon, but when i started it, it shows me the screen with "The bootloader is unlocked and software integrity cannot be guaranteed"

The warranty is gone, but it's ok.
I have relock the device with fastboot, the name of the rom seems legit.
My question : is there still any security risk ?
Thanks

Unless it was specifically advertised as unlocked and you specifically bought it for that reason, I'd reset the phone with an MSM tool or similar.
Maybe I'm just OCD. I factory reset every electronic device I buy before setting it up.

I can't find a copy of the device reset tool on the forums or the manufacturer website.
I would research the issue further on the following sites:
How to Reset the Motorola one vision
Motorola One Vision Questions and Answers (XDA)

Having a device's bootloader locked simply means that device only will boot into / run Stock ROM: This has nothing to do with whether Android is safe or not.

thanks, yes i have relock the device myself.
But is it sure that it’s now using the original stock rom ? And not a hacked one ?

YES, because original Stock ROM is signed by manufacturer: the bootloader verifies this signature.

Thanks a lot.

I can confirm twrp, but i cant use it since bootloader is locked, and there are no instructions really to unlock bootloader.

I dont know. Its not like another xiaomi phone.

I can confirm that this message is true on BS4
Only the parts from BL to TWRP are paid
And some people in China master these technologies, I also spent some money to get BL Unlock
But now there is no third-party ROM to install
So I regret paying to unlock BL
Because I want to change to a system that is more compatible with apps that require google services and has no ads in System
But now I can't do what I want

Yes, a guide to unlock the bootloader would be much appreciated. I have found the TWRP and would like to try and share once it works.

Question Bootloader Unlock?

It's still the early days before many people get these phones. I figure I'd ask the question: Which models, if any, will be able to unlock the bootloader?
Previously, I was told the USA models (even if carrier unlocked) could not unlock the bootloader, while the S. Korean models actually *could*.

Typically, Samsung devices with Qualcomm chipsets marketed in the United States are not bootloader unlockable. Exynos on the other hand usually are. No idea if this has changed in regards to the S23.

No changes at all. The ability to unlock the device doesn't depends on the SoC but rather to the region of the device. The international variant of the phone can be unlocked without any issue

77% of us in the UK in the S23U poll are unable to unlock

just in case none of you guys haven't figured it out the S23s are all unlocked, but are temporarily networked lock depending on how you got your phone. I know this because Samsung told me both the american samsung and the Korean Samsung also my program are it has roots for the devices.. It just don't have a way to network unlock them

To clarify: you mean all s23s are bootloader unlockable and able to be rooted, install custom recoveries/ROMs, etc?

Yes, they can all be rooted and more. You just have to be the one to download the firmware you want and use the method that you want this program supports Magisk root. you can also technically flash firmware as if you are using Odin

Just to clarify - approx 50% of us in the UK are unable to unlock the bootloader as Samsung chose to enable Knox Guard active (01) meaning OEM unlock does not show
Samsung is ambivalent about the issue
UK ONLY - do you have oem unlock available?
As the titles states, it'd be good to understand how many people have the normal oem unlock available in developer options. A couple of us have received various s23 models with kg status active and no oem unlock available in developer settings...

SUCCESS! [BOOTLOADER UNLOCK] Nokia C2 Tava TA-1218.

[BOOTLOADER UNLOCK] Nokia C2 Tava TA-1218.
Requirements:
Windows PC
USB Cable
MTK Drivers and LIB USB
I was actually approached by a person from XDA named @Soadeathdealer who gave me remote access
to unlock his phone's bootloader. I'm thankful that he let me use his device for this experiment.
This phone bootloader was successfully unlocked using Unlock Tool which is paid software
but you should be able to unlock it using mtk client as well.
Please PM me if you need any help.

Hi!
I downloaded Unlock Tool but it needs to be activated (paid for). How did you pay for it? I clicked the "activate" button and it went to an obscure reseller page with no info on how to pay.
Thanks in advance!

What do you need from me? The bootloader codes? I found it odd they only wanted the IMEI number.
I already tried 'fastboot oem unlock' that did not work. Just let me know what you need! Thanks!

No you just need to setup MTK drivers and I'll do the rest.
But I'm away from my computer today. I would be able to help you tomorrow.
