An LG L90 work also works for LG Volt LS740. The steps to access it are as follows.
Note: This assumes you’ve already rooted manually or with Towelroot and know what adb/fastboot is.
How to enable fastboot for LG Volt LS740:
First, backup your LG Download mode (laf) with this code, so you can use LG Flash if necessary.
Run the following code to zero out laf:
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:
You delete the laf partition, which forces fastboot mode and takes the place of download mode.
IF you want to return the phones download mode
You can skip flashing the laf.IMG back before exiting fastboot if you wanna leave fastboot mode enabled instead of download mode. But be careful as without download mode you might not be able to recover from a brick.
So think about what you feel is more useful. In fastboot you cannot flash /system/ back because it is too large.
Disclaimer: This is what i did and it worked. Try this at your own risk, always assume anything you do on your phone will result in a brick and it will be unrecoverable.

I was all good until I got to this command
“dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf”
Andit responded with:
“/dev/block/platform/msm_sdcc.1/by-name.laf: write error: No space left on device”
Can someone please tell me how to fix this? I’ve tried doing a reset but that didn’t solve the problem
laf.exe Google results say its a virus.
