OEM Unlock Doesn't show up on Samsung Galaxy a21 (SM-S215DL) - General Questions and Answers

It's an old phone, I wanna root it, but no matter what I do "OEM Unlock" never shows up in the settings. I've reset the thing multiple times, changed the date, messed with auto updates a lot, but nope never shows up.
Some info that's probably useful. I got this phone from straight talk (a Walmart carrier, don't ask why it's a long story yes I know it was a terrible idea, Walmart was lying to us saying we needed to buy a phone from them and I didn't want to fight), and when trying to root it a friend who knows a lot more than I do told me to enter odin mode, and instead of that, in big red text (slightly covered by the camera) it says "entering fastboot mode...", (shown below) and doing "fastboot devices" spits out "R9AN90BYY5J" as the fastboot device, so I don't know.
I tried doing it via pc but when I do "fastboot oem unlock" (because apparently its not a real samsung phone so i should use fastboot) it says "
FAILED <remote: 'unknown command'>
Fastboot: error: Command failed"
from what I've heard (from a source I don't remember, and the same friend) apparently you just can't root us model phones, I tried all of this on my Galaxy A50 as well (I got it from inland cellular and apparently it's a verizon model phone, might have something to do with me going through verizon I don't know, but it is a real samsung phone) and oem unlock still never shows up. So am I just screwed?

Fastboot oem unlock freezes phone

It's my first post on this forum, so I'm saying hello.
I've recently bought Nexus S which after turning on is stuck on Google logo, but I could enter fastboot and recovery. But it has locked bootloader. I tried unlocking it by "fastboot oem unlock" but it asks me if I'm sure and then i click yes it freezes (phone not fastboot). I tried it using different drivers, machines, operating systems, cables, but still nothing. Unbrick tool by AdamOutler says that "device not found". When trying to flash stock image by Odin on the phone there is message if I'm sure that I want to unlock bootloader but with nothing to choose, and after while it shows by red characters that system image was verified.
I don't know past of this phone. (I have no idea, which version of android was it running)
I'd be extremely helpful for any kind of advice.

[Completed] Moto G2 rooting issues

My phone stopped working all of a sudden, and when I restarted it entered the fast boot mode iteratively.
If I select recovery or normal boot, or whatever it says the same msg, "recovery image not valid".
The phone was unrooted, so I thought of rooting it.
I dont remember the status of usb debugging in my phone was on/off, now no chance to check it either.
But i could run the commands from the cmd to get the unlock data code, as well i received the code from Motorola to unlock.
When I tried the fastboot oem unlock (20 digit Unlock code)
I used to get a reply: Unlock data invalid!
Failed (failed remotely)
And some time info of time ~10s.
I also ran the getvar all command & noted the cid= 0x0007 (I dont remember count of 0's but ending was 7 which I found the device is unlockable)
I live in India & the device is not network restricted and I have bought it from flipkart.com which was sole retailer of Moto devices in India.
Can someone plz help....
Thanks,
Swapneel

OEM unlock Unknown command

I am about to lose my mind if I cant figure this out.
I have an LG Stylo 2 Plus model LG-K530F, and i have been trying to root it for several hours
I have certainly clicked the "Enable OEM Unlock" option, but no matter how many times I try the command on ABD, it will not work
I have made sure that my computer recognizes the device, and from the command prompt can successfully boot it into fast boot with "adb reboot bootloader"
I've poured through all sorts of threads and forum posts about other lg stylo 2's with different model numbers, I've factory reset the phone preemptively from suggestions, yet no matter what I try, I cannot get past "fastboot oem unlock"
And just to be sure, I have done a "fastboot flashing get_unlock_ability" just to make absolutely sure I allowed to unlock it.
It just *won't* for some reason
"fastboot getvar unlocked" tells me that it is not unlocked already
"fastboot oem lock" works and says its already locked
Does anyone have any help for me? Any suggestions? A thread or post I haven't seen yet?
The phone itself seems to imply that i need a code from LG to unlock it, there is a part on the fastboot menu that says "2) Write Unlock Key - fastboot flash unlock unlock.bin" but the LG developer website does not support this phone, so i wont be able to get one from them
lol yes you need the unlock bin from LG...
good luck

OEM unlocking greyed out on factory reset phone bought direct from Google

Hi,
Trying to install Lineage on my old pixel 2.
The phone was bought directly from Google. When in Fastboot mode, it says on the screen that the boot loader is locked. When I run "fastboot flashing unlock" in a shell from a connected Mac, is says:
FAILED (remote: 'Flashing Unlock is not allowed
')
fastboot: error: Command failed
So I went into the settings on the phone and the OEM unlocking option is greyed out and says "Connect to the internet or contact your carrier". It is connected to the internet, however.
Thanks for any help,
A
Same problem here. Does anyone have a solution?
Same problem too. Hard reset is supposed to solve this.... but not for me. oem unlocking option is ungreyed then , but unlocking bootloader is still impossible.
Have you connected to the Internet with the device?
Try dialing this: *#*#CHECKIN#*#* (*#*#2432546#*#*), you should get a notification that says "checkin successful" or something like that. If OEM unlocking is still greyed out, reboot the phone and check again.

I don't have any other suggestions, then.
When the device connects to the internet, it's supposed to check the IMEI against a whitelist to determine whether OEM unlocking is allowed. If it doesn't do this, it's possible that the device is either defective, or is actually a carrier branded device. The latter is more likely with older phones like the Pixel 2 that have been out of production for quite some time.

What Am I Doing Wrong? (Rooting/Bootloader Unlocking)

Hopefully someone here can help me through my problem,
Device Details: BLU G60/BLU VIVO X6
Android 9/Pie
OEM Unlocking: Allowed
USB Debugging: Enabled
Hey, I'm pretty new to this way of customizing my phone (adb, root, roms etc), and I'm trying to root my phone with Magisk. I have a patched boot.img, my bootloader is allowed to be unlocked and I'm doing exactly what the root guide says (https://www.mobilewithdrivers.com/magisk-root/blu-g60-64gb-3gb-ram) but it wont work, I keep getting different errors and I see all my fellow droid users so happy with their rooted devices, I want to root mine too. So what I'm asking is; Can someone with an actual brain (Mine wont work) to try and help me out or walk me through step-by-step?
Thanks for reading!
Some of the issues I have:
"adb reboot booter" and "fastboot reboot bootloader" both reboot the device but in the top left corner it says "fastboot mode" and just freezes, when I do any command it just says "device null" but when I reconnect the USB cable, it just powers off.
"fastboot flashing unlock" results in "FAILED (remote: Not implemet.)" Yes, spelt like that.
"fastboot oem unlock" says, unkown cmd...
Wrong driver in use. Use the one provided by BLU suitable to your phone.
i couldnt find any drivers for the exact device, only google ones...
any ideas?
If you have a mac, you could try that. They usually don't require drivers.
