1) Which way are you trying to flash back to stock - kdz or tot? If tot is failing then try to kdz, if kdz is failing then try the tot restore...here's a guide with all you'll need for either flash method: https://forum.xda-developers.com/showthread.php?t=2785089
2) Try using the original LG usb cable if you have it and use a usb 2.0 port while flashing.
If you have download mode one of those flashing methods should work for you as long as you have all the drivers installed and the correct files to flash.
Good luck :good:

Bricked Phone

My lg e980 has vanir 4.3 and will not boot to recovery, and will not flash in download mode with lgflashtool. I cant use the kdz method because the e980 uses .tot files. Can someone explain how to convert them? Ive gotten the tot file extracted but cant turn it into a cab file to encrypt to a kdz. HELP!!!

[Q] Can't access recovery mode via hardware, only via software

Hi guys,
I have a F400L which has been giving me all kinds of havoc. Not sure what the main problem is but it constantly reboots, wifi and bluetooth don't work and I can only access recovery mode via using an app like Flashify (hardware buttons do not work).
Might have something to do with using a modified dll file from this thread http://forum.xda-developers.com/showthread.php?t=2799703 (my f400L thought it was an f400k and i couldn't flash the normal f400l dll file)
Please I need HELP

I think the only thing you can do is flash the KDZ for it. If you can still get into download mode flash the KDZ using CSE Mode which will wipe all partitions and rewrite the correct ones
Why didnt you flash the KDZ instead of using the DLL+TOT Method?

Just tried that. Unfortunately still having issues. Doing a bit of searching and it appears similarly to what is happening in this thread https://productforums.google.com/forum/#!topic/nexus/X6ZjAAauATc[1-25]

So just to be clear
You flashed the latest KDZ for F400L using CSE Flash Mode in LG Flash Tool? Is wifi and bluetooth fixed?

How did you try to get into download mode? Twrp can boot into download mode and also did you try the manual method to get into download mode?
Also how did you you flash the kdz because technically when you flash a kdz it should wipe twrp recovery and return you to stock recovery.

Internal storage is empty and the download mode don't go, I flashed the same firmware for unroot the phone but don't go. I've tried doing this http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359 and the phone goes.

Hi, I have nearly the same Problem. How you wrote I am in the download mode. but I can't get an usb-connection to the PC. I stored even the kdz file in the intern Memory, but I have no Chance to get it wether in download Modus nor in twrp Modus. What do you mean with "now flash your rom with lg up" . What is lg up??

Hi, I solved my Problem bei using Google Universal USB Drive. There it's possible to specify your item and edit the right ID's. There is a description in the net. After the USB ist connected now, you can normally Flash your Gadget.
