Unable to unlock bootloader (OEM unlocking disabled)

Hello,
I couldn't unlock the bootloader as the OEM unlocking's disabled and i can't access system! Everything's erased!
Any help????

A bit more info might be helpful mate.
What did you do to arrive at the situation you are in?
Can your pc see your device via ADB and if so what are you using: latest platform tools or toolkit?
Can you boot to stock recovery or bootloader?
Without any of the above info its going to be extremely difficult for anyone to give any kind of answer.

The device isn't recognized via ADB.
I can boot to Bootloader
The phone was working fine with the latest google stock android 10, i decided to lock the bootloader cuz the phone was getting overheated so i thought it'd be a good idea to lock the bootloader. Prior to do that, it asked me to erase everything! I erased everything and when i tried to reinstall the stock image it asked me to unlock the bootloader!!
The problem is that USB debugging isn't enabled and the phone is empty with no system!

Ouch! That's a right old situation you have there mate, with no OS installed a locked bootloader and no ADB function I'd have to say your phone is non recoverable!
Sorry mate but I can't see anyway out of that lot.
Maybe someone else a bit more knowledgeable might chip in but I'm deffo out of ideas.

Thanks for help anyway,
But there must a solution to this! I mean my phone isn't under warranty and I'm willing to go for paid services to unlock the bootloader!

Try switching slots, assuming the pixel is an A/B device. Maybe you still have a bootable system in your other slot and I don't think you need an unlocked bootloader to switch slots

Make sure you have the latest fastboot. On the bootloader your phone will either say "slot a" or "slot b" and you should type "fastboot --set-active=b" if you are on slot a or "fastboot --set-active=a" if you are on slot b

still didn't fix the problem... any probable solutions please?

Oneplus 7 pro bricked bootloader lock

Hi guys I have a OP 7 pro bricked (boot loop), I try everything to un bricked, that is why I ask for any help. I use msm tool and install several zips but when the tool finish it still have the same problem, I can access to the fastboot mode but my bootloader is locked, so I cannot try the fastboot method cause my pc won't recognize when I connect my phone in this mode (I think that's because I need to have enable usb debugging).

I've got bad news, if your bootloader is locked and MSM tool fails you will most likely have to send it in as it will no longer be easily fixable, I unfortunately had this same issue on my OnePlus 8 and learnt the hard way.

You said that you "cannot try the fastboot method" because your PC won't recognize your phone... did you install Oneplus fastboot drivers correctly? You should be able to access your phone in fastboot, even with bootloader locked.
Try with another PC too. Just my 2 cents, sorry if this doesn't help you...

First thank you for your time.
I though that too, but i didn't do it , maybe is because I read that in order to use this method (fastboot), oem unlock and usb debugging have to be enable on my OP 7 PRO
Ps: today I'll try again whit another pc, maybe it works, I think the Qualcomm drivers, adb drivers and OP drivers are a nightmare, who knows how many I've been downloaded those in order to make everything right
Sorry for my English I'm from Costa Rica

Sounds like he is stuck o. The older firmware that don't recognize oem unlock command. Not doing the developer preview upgrade then Ota out to regular firmware. Kinda sounds like what I started out on this t mobile one

Hi MadScientist do you hav the same prob? Didi you solved?. Like I said I think the fastboot method to unbrick doesn't work for me because we need to have oem unlock and usb debugging enable on the OP. I will use another pc to discard
Ps: don't know what you mean with "older firmware"
Since I don't remember what version of firmware I have I try the older 9.5.3 to 10... On oxigen. Even i read that someone resolve his problem installing the Chinese version (hidrogenOs) I don't remember the exact name

How did you unlock the bootloader?

simple , go to about phone and try to find build number,
after you find build number tap on it until it says you are in developer mode
after that head on to developer option (it may be inside about phone section or above about phone section) turn on the option which says allow oem unlock. then,
just reboot to recovery mode either by pressing volume up or volume down key with power button.
after you enter recovery connect usb cable and open command prompt in pc and make sure that lg device drivers are installed on your pc also make sure you have adb and fastboot installed.
ok, after all this type command
adb devices
if any thing shows us then you have successfully connected your device.
after it type
adb reboot bootloader
then your mobile should restart and show fastboot mode in screen
type command
fastboot oem unlock
and done your bootloader is unlocked.

I meant TWRP recovery . After you've unlocked the bootloader where did you get a custom recovery to flash for the LG k51. From what I saw on Team Wins website, there isn't one.

I doubt that's going to work, but let me know if it does. Carriers and manufacturers use a variety of sophisticated security schemes like requiring lengthy codes that only they can provide, etc to purposely make it very difficult to unlock bootloaders. Tmobile gave me a K51 for free. They apparently feel the have to pay for it by spying on me. I bought a moto g7 plus unlocked for $117 directly from Moto and put Lineage on it, no gapps Would love to use thie k51 though if anyone figures it out because it's more waterproof and bigger battery.

Whether device's bootloader is unlockable / device's Android is root-able or not you easily can find out by means of ABB:
Code:
adb shell "getprop ro.oem_unlock_supported"
If returned value is 1, then it's supported otherwise it's not.

and let me guess my doofus luck im guessing no way to unlock it with out a P.C. like nuttin at all?

Absolutely no of the crap above works at all in any capacity especially sprint. Generic postings like hold volume down and power also doesn't work to go into fastboot so if you guys are following the advice of some of these guys don't because you'll drop more money on a new phone then you will unlocking it some variants verizon is one I think you have to call LG I know I spent 6 hrs on the phone with "tech support" aka "jokes with a screen to read from" to FINALLY get into touch with an engineer who told me the only way "NOW" to unlocked the bootloader is in his office which means it has to be depot to be unlocked which as of this moment lg is not doing that WILL change in the future that was 12/03/2020. Even running external adb with kali linux to hack it broke the bootloader and sends you into an infinite reboot loop

This returns no value on a locked bootloader because even with Dev. Opt. Enables its still read only until bootloader is unlocked this is verified on two carriers k51's sprint and att. However it is unlockable we haven't found it and/or LG has not added this service to their site which is where you will get the info needed for the unlocked.

Oh my. You know you need to do all this from a computer, right? Can't do it in an Android terminal because fastboot commands are only valid in a phone's bootloader environment. And if you didnt know that then rooting and all of the dangers that come with it just isnt for you. But yes, it's rootable. So here you go anyway.
Reboot the phone to download mode.
Install LG's K51 usb drivers, and install adb and fastboot, on your computer.
Open a command prompt and type: fastboot oem unlock
If it does anything other than pat you on the back and tell you it's proud of you and how well you follow instructions, then go back and follow the effing instructions.
Otherwise, type: fastboot reboot.
Download magisk manager.
Do the magisk manager.
Use the LG flash tool on your computer to flash what you just did when you did the magisk manager.
And presto, you're rooted. Or I successfully left out enough info and you dont know how to use Google, leaving your device still not rooted. And thank god for that.

Ive been learning from xda for some time now. Bricked a few phones in my learning curve and tonight i had my first success with my g7, and wrighting this on my new k51. This is my first post and I think that was pretty rude of you to say. This is supposed to be a place to learn, share knowledge, and help those who are less educated. Not look down on people and say crap like that. If he wants to learn even if it takes a couple bricked phones to do it, let him. Either give him the proper procedures or dont say nothing at all. How long did it take you? How many phones? Its taking me quit a while but i am finaly getting somewhere. Keep with it guy. Dont let this dude, or any one else for that matter, bring you down.

Yo Ken,
So your K51 rooted?
If so, maybe you could provide a step by step?

I haven't done this yet but is it verified working? I did a google search came across the method to do the unlocking but it showed it was a failed project?

That's one of the guides that I mentioned that I tried. After using both unlock commands the response was FAILED (remote: unknown cmd.) I tried to use the fastboot OEM device-info command and got the same response

Tablet's OS is Android 11 GO, it got released 2020.
Is "OEM Unlock" option provided in Developer Settings? if so have you turned it on and afterwards rebooted the tablet?
Have you installed the Fastboot driver that's suitable to tablet?
If Fastboot returns "FAILED: (remote: unknown cmd.) " then Fastboot is obviously not supported.

I realized i had my command line in the wrong place and i corrected it and now the commands are recognized but they are still failing. I do have the oem unlock option turned to unlock and im using the adb and fastboot quick setup from xda to use on my computer. I honestly cant figure out where im going wrong this time. Ive used adb and fastboot commands before. Im no expert but im not totally green either. Still thank you guys for attempting to help me out. It really is appreciated

Are you talking about the M8L 2022? I've unlocked the bootloader but can't get it back to recovery and its FRP locked so i can't use ADB. ugh.
Also, its a Unisoc chip I think.

You have to use a modified fastboot and get the identifier token.

Look up modified fastboot for spreadrum devices. There is also a guide on hovatek forum.

For anyone and everyone who has had any trouble locating the firmware files (.pac) for the 2022 BLU M8L tablet, I FINALLY, after more than a month of searching found them on needrom.
Link is: https://www.needrom.com/download/blu-m8l-2022-m0220w/
Since idk if the link will be redacted or edited out, you can also google needrom and M0220WW

Be carefull when downloading the fireware for the M8L and pay close attention to the version your needing. From all that I gathered, there are mutiple versions...M0170WW, M0171WW, M0173WW, M0174WW, and the one I have that I have yet to find anywhere on the net. Its the most recent ..the M0176UU. If anyone happens to have this version, please make a full backup image and post it here. Thank you

Question Locked Bootloader while rooted on the moto xt2215-4.

you guys knows what that means. I can't get it to do anything. Can't use any of the tools. Flash permission denied on everything. Even the Motorola rescue assistant tool doesn't support the device. Does anyone have any recommendations? All I can boot to is a locked Bootloader mode

Can you unlock the bootloader again?

Nope. OEM unlock is not turned on in settings. neither is USB debugging.

So you're saying you locked the bootloader on custom firmware, and while Android still runs, you can't unlock it again?
This is why you should NEVER lock the bootloader on custom firmware.

Sorry to hear that. If you're unable to unlock the bootloader with fastboot commands, I don't think there's anything you can do. I assume you don't have root?

you try and EDL cable yet? if you don't have one you can make one by stripping back a bit of insulation and shorting the black and green together with the device off, then at the same time click all three buttons 3-4 times until you see the 9008 port show up in device monitor (WINDOWS)

if that fails and you're feeling brave (or you have really good anti-virus software) you could always give something like this a shot
