[HELP] Cannot unlock bootloader! - Samsung Galaxy A50 Questions & Answers

Hiya, About a year ago, I got an a50. I instantly regret it as it was slow and janky. I would like to install stock android of lineages. When I try to enable OEM unlock, well, there is none. Is there any way I can unlock it from a PC, or download TWRP without it being unlocked?

(oem unlock )

Hey guys and gals, I enabled developer mode and noticed that this device has the OEM unlock option not sure if that is similar to the nexus 6 as far as unlocking the bootloader to root but pretty sure it may be..fingers crossed and I wouldn't take any rom updates until we know further about root.
Yeah notice the same thing on my phone. I enable but not sure what it does yet.

The OEM Unlock does not unlock the bootloader, it only "allows" the bootloader to be unlocked.
If you don't allow the bootloader to be unlocked then you can't flash roms, kernels and you can't
root the phone.
This is why the verizon and at&t Note 5 and S6 Edge+ phones cannot be rooted and they cannot
have custom roms and kernels. They lack the the option of OEM Unlock because they have locked
bootloaders which is unlike our phones. The bootloader in our phones are not locked.
Good luck,
Have a great day!
My Verizon Edge+ has OEM Unlock on it, but I have no idea what it does. I'm searching the internet to see if anyone knows.

The important thing is to always leave the OEM Unlock enabled.
But as I said before, doing that will NOT unlock the bootloader.
It only allows for unlocking the bootloader if the bootloader is
unlock-able. (which is not the case with Verizon's bootloader)
Good luck,
Have a great evening!

Try Depixel8?
Depixel 8 doesn't work because the bootloader won't unlock

Works fine
Not sure what you saw but unlocking the bootloader doesn't have any effect on regular fingerprint unlock for the phone. It will stop Android Pay from working and might do the same for MI Pay.

That's true but he didn't mention rooting his phone and it might not work the same way with MI PAY.

I think this is an misunderstanding because I just got my mi mix 2 as well and I thought the same, but it actually says that it just won't be as secure with the bootloader unlocked. I just read wrong.

About xiomi redmi note 5 ai fake rom and fake unlocking problem

I bought a xiomi redmi note 5 ai which contains a fake rom( 9.5.13.0.0 OEIMIFA). In developers option it shows me that my device is unlocked but in fastboot it is actually locked. I tried to unlock it but couldn't get succeed. I also tried xiaomitool, xiaomi flash, some adb and edl proccess but couldn't get any success. In forum I saw test point twice method for whyred but I couldn't active edl by doing this hardware functionality because my device is new and I am also a noob in those matter. My mi id also unauthorised. Is there any chance that I can flash Official China stable rom and get the official update??? I am so disappointed with this. Experts, please help me to flash official rom on note 5 ai. give e some solutions.
Yeah I wanna know about this topic too. Many sellers are sending unsealed products and bootloader saying unlocked.
I'm in this situation too! So sad
This is really weird....In dev options phone says "Unlocked" but when you reboot there is no "Unlocked" sign under Mi logo...WTF?????
You will need to give some more detailed information for people to help you. Go on the guides section, find one of the many bootloader unlock guides and follow it step by step: at which point does it not work, and what kind of error do you get?
You also mention your account not being authorized: if that is the case, then you absolutely need to get it authorized first, there's no way around that (short of finding someone with an authorized account to help you, I guess).
By the way, I would not focus too much on the fact that Developer options report the device as unlocked, if the ROM is unofficial, that is easy to fake. Whoever flashed the u unauthorized ROM must have then relocked the bootloader after flash.
this is why xiaomi has changed the way bootloader unlocks to prevent sellers from doing this.

To my knowledge, the new unlock policy just adds more time before unlock and makes it harder to use the same account for multiple unlocks. I would say it discourages sellers from doing this, but the more resourceful ones will keep doing what they always did, while us users have to endure the whole thing.
I got my redmi note 5 ai, it was already unlocked. can someone point out if it's good? In developer options says unlocked. I turned on usb debugging but OEM unlock is greyed out. Verity mode: true, device unlocked: true and device critical unlocked: true
My first R5+ came with an unlocked bootloader but the unlock process made it for the seller can corrupt eventually some partition or even unsuccesfull, they are not intend to unlock but change a chinese rom for a global and through the process device could get unlocked (time before, I guess not actually).
The most indisputable way without a doubt to know this is simply going to fastboot mode and typing
Code:
fastboot oem device-info
so fastboot reads at a low level directly in the right partition. There are some discussion on where is place this condition, some thinks that is in bootloader itself but others believe that it is in persist partition.
That's what I did. What do you think?

Thanks for the confirm. Still can't figure out how to turn on OEM unlock. Maybe cause I haven't done a mi account yet.

You mean unlock OEM in developer options? turn off USB debugging and then turn on again and now enable OEM unlock

If it is in a greyish, as unmarked so you can touch the toggle but is in positive OEM unlock? then don´t worry about that.
Just look at it before and after to do some update.

Question i heard something about bootloader un/relocking

is it true that relocking a unlocked bootloader erases everything, but you can re-unlock it ever again on xiaomi devices?

Just use xiaomi flash tool, as it can also re-lock your bootloader.
Hi,
I am new Poco F3 owner,
I got the Amazon black Friday deal £50 off,
my variant has 8gb of rom & 256gb of ram, all this for £269.00p,
what an Amazing price and also comes with 2 years warranty here in the UK.
I have been a LG users for many years, using the (G2, G4, and for now a G7) .
I have installed many custom roms on these devices over the last 8 years.
Unlocking/locking there bootloader have been relatively straight forward.
I asking the same question that I am sure has been asked many times before,
once my 7 days are up and i have unlocked my bootloader and i then lock it again,
but then further down the line i decide to unlock it again,
do i have to wait another 7 pointless days.
I'm loving the new poco F3, apart from the firmware is a bit restrictive,
hence why I'm unlocking the bootloader.
What a great community the F3 has , long may it continue,
regards,
Johnr64

No, you only have to wait the first time.
This waiting time is not so pointless as it seems however. It is there to discourage a.o. the many traders flashing (often fake) 'global' roms on Chinese phones and selling them as genuine global models for extra profit. So in the end it's only for your protection, because flashing roms invalidates warranty.
so just to clarify there is no limit on unlocking and relocking this phone right?

xiaomi unlock tool its infinite dont worry, but be extreme cautious when you are locking your bootloader make sure your are in your right stock rom and dont forget to unlock again when you are going to flash custom roms and recovery
To lock the bootloader you can simply use "fastboot oem lock" in fastboot mode. Note that doing so will (obviously) factory reset your phone.

ok, another question:
in the event where i lose my phone an unlocked bootloader can bypass any password protection if they have the knowledge right?
is there any way to protect the phone from this?

If you mean screen lock, yes they can bypass it. But they cannot get into your banking apps or others which have their own passwords.
If you are really keen on it, just lock the bootloader.
