The prompt may not appear when your phone is locked (I mean unlocking a home screen only). Try unlocking your phone before putting in a USB cable. If the prompt is still not there, it may mean you've already accepted all ADB connections from this PC and something is wrong with your drivers or your USB cable. Check if your USB computer port is USB 3.0 or USB 2.0. Sometimes it helps to use USB 2.0 if available.
Try a few times to plug USB cable in and out. It should eventually appear ;)
 
"/sdcard/Download/laf.img" does*not exist
"/sdcard/Download" it is the same folder as "/storage/emulated/0/Download"
(Download folder in Internal Storage)

but
"/storage/externalSD/Download/laf.img" exist
(Download folder in External Storage)

and it is solved?

i will try
 
Remove Lg drivers.

Use "Google USB Drivers". Google it! Search for tutorial too!
Select the "Android Composite ADB Interface" driver option. Install by "driver update" in "devices manager".

@Mystery_Flasher

it is by drivers of lg?

or its the adb?

ClauvanPdST may be right - I'm not sure if you have properly installed your ADB drivers, too.
Do you follow the exact instructions provided in the thread? http://androidforums.com/threads/unlock-lg-l70-bootloader-unlock.862585/

I wonder if you also have your Busybox installed as instructed? <-- you didn't mention it.


Let me quote the thread:

What you need:

Windows users, you need fastboot and adb installed. All of which is included in the zip for part 1. Linux users, same for you, I have included the adb and fastboot binary but I had a problem with the adb not working in the package, might be something I edited in the shell script so install adb in your bin directory (I can help if needed).

NOTE: Must have busybox installed on your device, have USB debugging enabled, and the phone plugged in and set as charge only.
 
I hope you have also opened BusyBox app from the app drawer and used an option to install it ? Installing and app itself from GP is not enough. <just checking>

My last idea for now: please try to open CMD but use "run as Administrator" option in Windows. Then in CMD proceed with the whole procedure.
 
I once had the same problems. This is an attempt to help you!
But I avoid to use script. I just follow the steps tutorials and steps from within the scripts. And always proceed hand!

Disable all.
Activate the dev options;
Revoke the old USB debugging permissions in dev options and try again!
Enable USB debugging in dev options;
Recognition of the device via the appropriate driver installed properly, OK?

Remember to choose aboot.bin for your phone model!

Only this guide works for me (but with google drivers):
http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772

I took the LG_Root.zip, and updated both the busybox file to 1.24.1 as the version 2.46 of supersu to the 2.68 version, keeping the previous name. The tools are attached.

You need to find out what the serial COM port (COM3 or COM4, etc) on which your smartphone will be connected when you are in Download mode (device off, Vol Up and connect the USB cable).

Because aboot is patched? Or because aboot is not recognized as the original version? Or is a RAW image aboot partition? The developed aboot file has a size of 1 MB. A RAW image aboot partition, is about the size of 2MB. Because RAW image keeps the partition size. No, the size occupied in the file system.

I believe that the RAW image is unknown. Unless you provide your identification, and the tool has features for recognizing this ID.
