Need solution for 'DBI err fatal! blabla" for LG L80 D380

Dear master, I have problem with my LG L80 D380, it says "DBI err fatal! Demigod crash handler blabla".. I know there are some forum about it, but it's for LG L70 or G2/3, and mine is L80, yet still I can't understand what they say, no step by step tutorial and it's so complicated master... :crying: I'm newbie, I can only rooting, and do some firmware upgrade things.. my life is over..
It was the purple-screen error when I entered firmware upgrade mode (S/W upgrade, hold vol+ then connect usb), it means that there is no "firmware upgrade mode" for this condition....
here is the problem:
