Default How to: Enable fastboot and unlock bootloader, No flashing needed. WORKING.

Proof:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem device-info
...
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Charger screen enabled: false
OKAY [ 0.012s]
finished. total time: 0.013s



^C
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock
...
OKAY [ 0.004s]
finished. total time: 0.005s

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem device-info
...
(bootloader) Device tampered: false
(bootloader) Device unlocked: true
(bootloader) Charger screen enabled: false
OKAY [ 0.013s]
finished. total time: 0.014s

C:\Program Files (x86)\Minimal ADB and Fastboot>

This is all that differs after running fastboot oem unlock



How it works:

Follow this exactly. WHEN YOU ARE DONE IN FAST BOOT MAKE SURE TO RESTORE THE LAF.IMG
fastboot flash laf laf.img

I made sure to do this so there were no unintended consequences. You delete the laf partition, which forces fastboot mode and takes the place of download mode. I dont know what would happen if you didnt restore the laf partition before exiting fastboot.

So this method will unlock bootloader?

It returns device unlocked true when queried so I'd have to say so. There's no real reason to unlock it yet as we don't have a recovery or rom and there's always a chance of bricking your device.

Angry this si how i unlocked my boot loader

1st comes 1st lg ls740 this is to backup the laf partition, i recomend yall bakup,recovery an boot as well just in case

Note: This assumes you've already rooted manually or with Towelroot and know what adb/fastboot is.

First, backup your LG Download mode (laf) with this code, so you can use LG Flash if necessary.

adb shell
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/laf of=/sdcard/laf.img.

Run the following code to zero out laf:

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
(i did this and my volt told me the memory was full but this still got me into fastboot

adb reboot

For whatever reason, you won't be able to access fastboot via "reboot to bootloader" like most phones, so you've got to do a key combo:

Power Off
Unplug USB
Hold Volume Up
Plug in USB



step 2


fastboot oem device-info

should look something like this ...
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Charger screen enabled: false
OKAY [ 0.012s]
finished. total time: 0.013s

step 3, fastboot oem unlock


should look like this,
...
OKAY [ 0.004s]
finished. total time: 0.005s

DO NOT skip this step before shutting off or rebooting the phone

WHEN YOU ARE DONE IN FAST BOOT MAKE SURE TO RESTORE THE LAF.IMG

fastboot flash laf laf.img

p.s if you backup your laf.img make sure to move it off of the internal storage to the sd card or computer or you will not be able to acsess it



p.s my lg olt ls740 is unlocked, woooot maby busybox will work right and afwall

So correct me if I'm wrong but when I press volume up + plug in the usb, I'm in update mode, and fastboot is hidden behind the update mode, if I do the command to backup my laf img it's backing up the update mode, and deletes the I'm on the phone? That's to have to re-flash the laf partition, my question is can I just remove the laf partition, forever?, so I can have access to fastboot?, add long as I don't touch the boot, it should start fine?

You could leave fastboot, but if you somehow brick your phone you might not be able to recover from it without download mode.

Cool that's what I thought, and you can recover, just do fastboot flash laf laf.img, if I'm correct? Add long as I have fastboot I'll be able to flash the download mode?.......Sorry correct me if I'm wrong but isn't the laf file a copy of download mode?
