Question Can't unlock bootloader and flash TWRP on Samsung Galaxy A12. - Samsung Galaxy A12

Hello, everyone.
Today I'm trying to root my phone, but I am not succeeding to do it because I can't unlock the bootloader and flash TWRP.
Currently, on the developer options, I've activated and grayed out OEM unlocking, and also I have unlocked the bootloader on the download mode.
Is there any reason why can't I unlock the bootloader, and why is this happening?

Hello. I recently got a Pixel 4a and have been trying to unlock bootloader and install Magisk to no avail. I can't even toggle the OEM unlocking option. As far as i know the Verizon version might be impossible to unlock bootloader. But i have no idea if my device is Verizon or not. After checking the device's cid adb return 000000. Am i out of luck here or is there something can be done? Thanks

OEM unlocking of Pixel phones requires internet access.
In my case trying to do OEM unlocking without internet access was the reason for the same greyed out button.
Did you setup internet access and restart the phone afterwards?
If yes, then I am out of ideas.

Flash Fastboot without unlocking Bootloader?

Hey, I am using Redmi 4 prime. I wanted to unlock my Bootloader. But Mi unlocker and adb says it's locked. So I want to flash the fastboot rom to fix it. Any suggestion?

Screenshot provided shows phone's bootloader is unlocked.
FYI: Fastboot is integral part of phone's bootloader, hence you must flash nothing to have it working.

It's actually not unlocked. It only shows it's unlocked. It's like a fake rom problem

Trouble unlocking the bootloader of a Samsung galaxy a30s

The problem here is that I can't access the download "menu". The phone has volume buttons and power button, nothing else. I can access the bootloader using recovery mode, but it throws me to the "download" section of the download mode, instead of the "menu" section of the download mode. The download "menu" can unlock the bootloader by long volume up. The download menu "download" can't do that. I have OEM unlock enabled.
Samsung allows unlocking the bootloader on the international versions of their phones.
Have you successfully enabled OEM Unlock option?

Baseband M215GDDS3CWD1-20230522142126 bootloader unlock

Hi Friends,
Does anyone know a solution to fully unlock the bootloader of latest Andoid13 1Ui5.1 Factory ROM which has May 1 Security update for shamshung phone? I cant flash any GSIs on it like before I updated from A11 to A13. When the same phone was A11 a few days ago the oem-unlock button was fully greyed out & all GSIs booted but not so after I upgraded to A13. Only one zip rom booted which was based on stock 1Ui5.1. I believe I tried everything I could. I cant use 3rd party softwares like Unlocktool, Z3X & BMB Unlock Tool as the zips are full of trojans as usual. Fastboot dowsnt work on shamshung devices & I couldnt find any adb commands to unlock the device. Please help. TIA.
