Root I Need Help! Please! I'm begging!

Hey Guys, i have an LG L70 D325 I can not just do nothing, if I try to connect in the download mode, appears the following message:

Secure booting Error! Cause: boot certification verify
[1450]-----------------------------------------
[1450]
[1450]Secure booting Error !
[1450]Cause: boot certification verify
[1450]
[1450]-----------------------------------------

And two seconds after the message above, appears a pink screen exactly like the image:

I can not access the download mode, I can not use the LG Flash Tool because when get 15% appears the message communication error between the computer and the device, I tried to unlock Bootloader, i used a tool called Recovery LAF, which says retrieve the phone boot, but without success because the device is not detected by program, the only ones who detects the device's own computer and the LG Flash Tool, but the computer show only two folders, one called "Verinfo" and another called "image" and the LG Flash Tool as i said, informs communication error between the computer and the device when i try to install the original factory ROM... nothing works, all because of this pink screen, this error DBI, it blocks and does not allow anything to be done, he tells instructions, but i do not have the rdcookie.txt files and rtcookie.txt ...
Please, I do not know what to do, I've tried everything I know and even I did not know to do work...
And sorry for my English is not very good.
 
Only LG Flash Tool, try with another usb cable....
The problem is in the device, not the cable, i tried two new cables and not work for all steps

With no download mode, it's dead. Theirs nothing we can do.

Unless.

Can you access Fastboot Mode?

Was WHAT thought, but I found a video that shows how to fix this error cursed, but is only operable on Linux and I do not have this system and for some reason my computer does not accept virtual machine, there is no way to clean it up and install from scratch ? Without being in download mode?
#Edit: And no, i can't acess the Fastboot, the pink screen appears before i make anything

What do you do to access fastboot?

Remember to access fastboot/dL mode you:

1. Take out the battery, make sure everything is OFF.

2. Plug in a USB, DO NOT PLUG IT INTO THE PHONE YET,

3. Hold Up Vol on the phone (while off) and then plug in the USB. It should avoid the Purple screen and redirect straight into Download Mode/Fastboot mode.

No, Purple screen again, and again, and again, oh gosh... I hate that error... Please, you have another tip? :(
 
You don't have to install linux, you can boot it from USB/LiveCD.
 
hmk, I'm outta luck. I've never seen this bad of a purple screen. Most can just access Fastboot and flash a LAF file.

Yeah, and the Internet, in my research I have found many people with these problems, and apparently, haven't a solution, all with LG phone...

How did you get this error? Flashed wrong boot, recovery, etc.

I do not know exactly what happened, five times different roms were installed to this device, but he spent a long time standing without being used, but i believe that purple screen is not hardware problem, is software problem, you understand? I think there was an error in the whole system, just can't understand where it happened! Need to fix this without technical assistance, here in my country these things are very, very expensive...

You don't have to install linux, you can boot it from USB/LiveCD.

I was so worried I forgot that detail! I'm already downloading a version to be boot on USB flash drive and will soon know if Linux can solve my problems! Hope so! Hard Reset tried today and didn't work, the purple screen appears even before the process begins...Today I tried all processes again on another computer with two new cables and even then it didn't work...
 
Hey Guys, I tried the Linux method, i used Ubuntu to do the procedure, but when connected the device to the computer, appeared the purple screen, which so far seemed indestructible, began to "blink", with a distance of three seconds between each blink, and Ubuntu simply stopped, with several messages stating "Unable to mount a 8MB drive" or something like that, every time the mobile screen blinked appeared a different warning, i left a few hours and even after all this time this damn error did not stop...
here's the link guide that teaches fix the error: http://androidforums.com/threads/gu...oad-mode-no-recovery-mode-no-fastboot.893311/
Yeah I know, do not speak exactly the DBI Fatal Err, but the symptoms are almost the same, no download mode, no recovery mode, no fastboot, no emergency mode, and when I connect the device on computer I see only the folders "Verinfo" and "image"...
