And the Problem That I Can not Put the phone into download mode que he ends up appearing this error.

Did you have a custom or a stock recovery in your phone? The way to put L7ii in emergency mode is this:
-Insert the usb cable into pc
-Hold Vol- button
-Insert the cable into your phone while you hold Vol- button and then release it.
Did you try to enter in emergency mode this way?

[Q] My LG optimus G E970 stuck at LG logo

LG optimus G E970 Download mode is working (No fastboot as stuck at LG logo), but error while flashing stock with LGNPST and LG Flash tool as phone is detecting as E960 instead of E970. I think I messed up while installing ROM earlier
Can anyone help me out and tell me what I can do next to unbrick my phone (get fastboot).
Any response would be appreciated.
Thank you and best regards,
Som
Hold POWER BUTTON for a long time until your 110% sure it's off.
Hold VOLUME DOWN and VOLUME UP and POWER until DOWNLOAD MODE SHOWS UP.
Download LGNPST and stock .bin and if you need help finding it, I can help.

I've been there and can tell you there is almost nothing on this phone that can't be recovered from. Understand that it will take some time and yes you need to open it up to short the pin but it does indeed work.
