e975 hard or soft brick.

Hi,

i followed a guide how to move back to the stock ROM on my E975, but the flashing process did not move further from 4%. If I now switch on my phone, it is always stuck in the download mode . I tried to repeat the flashing process with the original LG software upgrade tool, but encountered the same problem. After the third attempt, the tool was not able to flash anymore because the battery of the phone is too low.
If I switch it off and on and connect it to the USB charger, it does not charge but is still stuck in download mode.

Is my phone hard or soft bricked , and is there a way to fix it?

Thanks for your comments!
