Hey, my LG E440 shows a security error everytime I want to start it. I already tried to flash the stock firmware with LG Mobile Tool, LG Flash Tool and KDZ Updater. Mobile Tool and Flash Tool are showing me an error at 5%. KDZ updater fails with "Phone not found" error.
Im able to boot into download mode while connecting it to the USB cable. Without I cant get into download or recovery mode.
Can anyone help me? Im running out of ideas what to do.

S/W update mode is enough to do offline flash your kdz or recovery your phone via LG mobile support tools. Please select one of those 2 methods to recover your phone.
You need to unlock bootloader before install custom rom or recovery.
Take the kdz files from cmahendra's thread and use S/W mode to flash it.
Please don't forget to unlock your boot loader next time.

You could probably use LGNPST, I used it for my bricked E970. Google it and download it, then boot into download mode and flash stock firmware. Let me know if this helps. I can provide a detailed procedure if you'd like
i tried many methods for unbricking it...even in the lg flash tool it started but after 6% it shows error partition system change and on my phone it show D855v10i and on the next line it shows D855v10e.......and i cannot see any tot file for the version d855v10i....when recovery working ...i have tried adb sideload but it also shows error and now nothing works...no recovery no fastboot......i know there must be some way .....
Have you had any backups of stock or previous rom(working rom) ?
Try to restore that or download one at www.needrom.com
