that means you don't have a download mode image installed.
How did you go to 5.0? Via TWRP or a KDZ? (the answer to this question changes the answer I will give you on how to fix)

Twrp.. Androidnow 3.2

The only way to get out of fastboot mode is to use fastboot.exe and push the laf.img and boot.img to your phone to boot up. However there is no laf and boot images for your phone yet(I think) so there isn't any way to boot your phone up yet.

some one can help me please ?? the LL 5.0 is sucks

Please help me ! Up

I had the sam problem.Now it is working .So you need to download latest firmware for you lg model(kdz file)
Then use this guide: http://forum.xda-developers.com/showthread.php?t=2600575 (extract kdz file)
Now when you extract it find laf and boot there will be some numbers just change it to laf and boot.
In fast boot erase and flash it again.If you have d855 international i can send you these files.

You need to find a rom unpack it and do
fastboot erase laf
fastboot flash laf laf.img
Where laf.img is the laf partition fomr that stock rom you unpacked.
EDIT: VERY IMPORTANT I FORGOT:
You need to download an image that is the same as the version of firmware you are running now. Or if you can enter download mode and flash to stock.

One of these will work for you. I can't say which one because I don't know what your PC is seeing your phone as...
Test point(if your phone shows up as Qualcomm 9008 or your are stuck and have no download mode because your partitions are screwed up): https://forum.xda-developers.com/verizon-lg-g3/general/how-to-hardbrick-guide-using-test-t3276928

Once you get a functional phone again: tot back to 10b, root using the stump root apk, install rashr or flashify app to install recovery, download a bumped twrp IMG file from the twrp.me site, and use one of those apps to install it as a recovery image. No need to do fastboot and all of that, just be lazy and use the apps instead.
