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.

When I typed fastboot oem unlock I get a reply saying <waiting for any device>

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.

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

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.


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?
