[Q] bricked my lg g2 d802,not going into download mode + my screen has white lines topic

hello guys,im new here i need your help..
I bricked my d802 today,i was on stock kitkat rom,what i did was rooted my device with towel root and used Autorec to install recovery,it installed successfully,then i clicked ''go to recovery'' then all i get were white lines on one side of screen and rest of screen is black(cant see anything).. after digging for hours i came to know that it is because of different Kernel version,but now i want to know how can i flash patched Kernel? as my device is bricked.. It is also not going into download mode so i cant also flash a stock rom.. tried Adb but it is not detecting my device... im completely lost :(
A tutorial or help will be appreciated.Thanks im waiting for your replies

New lg g2 out of the box faint white lines all over the screen, normal or not ??? topic

I have a lg g2 out of the box faint white lines all over the screen, and i'm wondering is it normal or not ? I read a little today that there a 2 kind of screens out there. One screen is ok and the other has these white lines on it. I'm not sure if this is a defect or not. Some say these white faint lines are actually the digitizer visible on screen befause of the fabrication process. Other say that its kind of a defect and should return the product . My question is what is the truth ? is this a defect ? can it get even bad than faint lines in time ? or they will remain just faint lines ? Its not a deal breaker for me just yet , but if someone tells me that this will get bad bad :) I will return the phone . So please I need some imput
