[Q] Sprint Lg G2 No pwr, no download mdoe, no recovery, no LG logo topic

Please forgive the noobness...lol I have a Lg G2 from Sprint ls980. I rooted, no problem...went to flash CM11 and bricked it real bad. I can tell the phone comes on, but its a black screen. I am using Ubuntu 14.4 trying to get fast boot,or download back.
If, there is an other way to use Ubuntu to recover, or flash download mode to my device, would be EPIC...Will donate for the proper fix.....
Thank you in advance,
