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.(make sure phone is on and pluged in and android debuging is enabled

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

Bootloader unlock sounds like.
